Description

Utilize the compression air-conditioning system of environment water and ground as cold, thermal source
Affiliated technical field
The present invention is a kind of novel air regulating system of energy savings significantly.Its maximum characteristics are; The huge temperature difference energy that variations in temperature by utilizing environment water and terrain and opposite this physics law of direction that atmospheric temperature changes are contained is as the energy of air-conditioning, with compressed air as working media, the suction of realization and water body and terrain, heat release exchange, after obtaining temperature change, compressed air with atmospheric temperature generation temperature difference, flow to the user, use as regulating air for the user.Realize the target of air conditioning with utmost point low energy expenditure.
The present invention only needs to consume seldom the energy and promptly can be fixed users such as City Building, extensive industrial and commercial enterprises the air conditioning task is provided, and comprises new wind adjusting and temperature, humidity regulation three big functions.
Task of the present invention be satisfy the user to the air conditioning demand in, energy savings significantly, thus significantly reduce user's operation of air conditioner cost.Save social energy resource consumption.And possessed simultaneously completely to the feature of people's health and health with to the free of contamination feature of atmospheric environment.Economic benefit and social benefit with highly significant.Belong to the air conditioner energy saving technical field.
Background technology
We know that the people is life, is operated in the atmospheric environment.And people's body temperature is 37 degree.The preference temperature that the people feels comfortably cool is at 12 degree--between-30 degree, except in the minority in spring, autumn beyond the date, this can not depend merely on nature temperature in overwhelming majority places, the whole world and satisfy, therefore need to adopt the mode of air conditioning to carry out the air conditioning of work and living environment, when satisfying people's work and living to the requirement of temperature.The technology of carrying out air conditioning is exactly our present widely used air conditioner technology.Air conditioner is divided into large-scale centralized (cooling or heat supply) formula central air-conditioning and unit air-conditioning two classes of using for subenvironment again.The maximum characteristics of existing air conditioner are; Its regulatory function to air must consume a large amount of energy and could realize, this makes air conditioner become the rich and influential family of energy resource consumption.In a city, the hottest or the coldest in, the energy of air conditioner consumption even may account for more than more than half that the city total energy consumes.
Existing central air conditioner system can't realize regulating as required accurately in use, normally no matter particular user has and do not have, and looks building user as a whole, completely air-supply.For example common central air-conditioning in use, can not be according to whether whether the someone decides this room to blow in certain room, send same big air quantity no matter client is 100 people or 3000 people in the market, so in use, just have very big wasting phenomenon.Sometimes, the energy waste that causes of this phenomenon will account for the quite big proportion of air conditioner total energy consumption.
People require except the suitable requirement to temperature, humidity the air conditioning of work with living environment, also have one more importantly to require be the air freshness, promptly to the requirement of new wind, this is because except suitable temperature and temperature, people's eupnea also has airborne oxygen content, and health that waste gas content, particulate pollutant, bacterium and viral level etc. are important and comfortableness require index.And existing air conditioner must adopt the circulated air mode in order not increase expending of the energy, promptly require to be conditioned zone or room must with outdoor atmospheric isolation, carry out closed cycle and regulate.This just causes the contradiction of healthy and comfortableness and energy consumption.And health is the air quality index that necessarily requires with comfortableness.Existing like this air-conditioning just can only be made balance by between, introduces the new wind of some in adjustment process, and this just causes the rapid increase of energy resource consumption.And even so, air conditioner surroundings still is considered to not meet the air ambient of health requirements.Particularly central air-conditioning is considered to serious pollution and disease public dissemination source (seeing the appendix data), in all health and healthy data, all requires people not stay in the air conditioner surroundings for a long time.Most typical example is: during SARS took place, central air-conditioning was forbidden to use.
In addition, existing air-conditioning technical must use chemical substances such as freon as thermodynamic medium, these chemical substances all are poisonous and hazardous to the people, also to environment particularly atmospheric environment substantial pollution is arranged, for example freon is the arch-criminal of damaging the ozone layer of generally acknowledging and global greenhouse effect.And these harmful chemicals also need consumes energy to produce earlier to come, could be for use.
Therefore, existing air conditioner technology exist energy consumption height, contaminated environment, to many defectives such as the people is unhealthy.For a long time, people are in the improvement of making great efforts to seek air-conditioning technical.But because old technology thinking restriction, air-conditioning technical has not had revolutionary progress since be born.Just produced the commercialization result of some modified forms.
The invention technology contents
Different with existing air-conditioning technical, the present invention has adopted brand-new principle and technology to realize the task that air is regulated;
The A principle
The operation principle of system of the present invention builds on the range of temperature and the amplitude of variation of environment water and terrain, than scope and much smaller this important physical rule of amplitude of atmospheric air temperature variation, and on the basis of the huge natural temperature differential energy that this rule contained.
B technical pattern
The technical pattern of system of the present invention builds on the forced-draft technology, and the natural energy resources that utilizes realization of forced-draft technology and natural water and terrain to inhale (putting) heat exchange utilizes on the technology.
Principle A introduces
We know that in the Nature, the variations in temperature of atmosphere is the most violent.The highest very big with the temperature difference lowest temperature.On the contrary, the variations in temperature of water body and terrain is little much smaller.The temperature difference is very little.According to meteorological data, the atmospheric temperature in inhabited city changes between-40 °--and between-50 °, and the variations in temperature of most environment waters is at 0 °--between-25.
According to relevant geologic information, terrain also is a very big thermal capacitance body, and its temperature is not subjected to the influence of temperature basically and tangible change takes place, in underground this scope of 10--50 rice, and temperature acute variation how no matter, the temperature of terrain is constant basically.In the underground 7M--20M degree of depth, be constant temperature basically 15 °-25 ° temperature.Except the minority time in spring, autumn, in the time of most of, they and atmospheric temperature constitute sizable temperature difference.Therefore, in the time of atmospheric temperature generation significant change, environment water and terrain just are opposite with the variations in temperature direction of atmosphere.That is to say that in summer, when atmospheric temperature was very high, the relative atmospheric environment with terrain of environment water was a kind of cold body.And when winter, atmospheric temperature was very low, the relative atmospheric environment with terrain of environment water then was a kind of hot body.This temperature difference between the two constitutes a kind of huge temperature difference energy.This just provides a kind of engineering feasibility that utilizes environment water and terrain that temperature is oppositely regulated.This possibility has just constituted the physical basis of the technology of the present invention.
Technical pattern B introduces
The forced-draft technology flows to the technology that the user uses by special pipeline after being meant and utilizing air compressor that air is compressed again.The forced-draft technology is an ancient ripe application technology, and in the city gas industry, fields such as urban heat supplying, chemical industry are widely used.Its feature is to carry out the air conveying of big flow by pipeline.And can regulate by valve simply and easily.
According to above-mentioned physical principle A, in compressed-air actuated course of conveying, we just can utilize metallic conduit to realize the hot and cold energy exchange of compressed air and environment water and terrain synchronously.By this novel concepts, just invented the basic technique principle of native system.
Why existing air conditioner will consume a large amount of energy, its reason be it refrigeration, heat and the function of blowing all realizes by consumes energy fully.If the natural temperature differential energy that we can use a kind of occurring in nature to exist is realized refrigeration and is heated, the energy consumption that is used in the air conditioner so freeze and heats just can save, and so just can obtain a kind of air-conditioning principle technology of very energy savings.According to this invention thinking, this invention that just has been born technology.
The basic principle of the technology of the present invention and the principle of existing air-conditioning technical are diverse, its refrigeration with heat the temperature difference of the required energy from environment water and terrain and atmosphere.It does not use special thermodynamic medium yet, and what be used to that the user provides air conditioning service is exactly compressed air itself.The compressed air of system uses as thermodynamic medium again both as fresh air, takes into account two kinds of functions all over the body;
Compressed air is as thermodynamic medium;
In native system, be used for carrying out heat exchange with environment water and terrain, make the compressed air that flows to the user have the temperature different with user's atmospheric environment, mode by this compressed air with different temperatures is mixed with original air of user environment just can realize the air conditioning task to user environment.
Compressed air is as fresh air,
In system of the present invention: be with by having carried out heat exchange with environment water and terrain, the compressed air delivery that has changed temperature is directly used for the user to end user environment.
In system of the present invention;
Environment water: be meant and be used to carry out the river, reservoir, pond etc. of heat exchange, also comprise geothermal water from underground extraction, the production cooling water of enterprise, the utilized water body of types such as municipal sewage before and after treatment for system with compressed air.Can lay the heat exchanger of native system in the environment water.
Terrain: be meant that then conveyance conduit just is embedded in this depth bounds at the subterranean zone of the underground 5---25 rice left and right sides degree of depth.If conditions permit can be buried underground deeplyer, effect can be better.
Environment water and terrain are to treat as the natural cold and heat source that need not to consume energy in native system.In the project of reality, according to designing requirement and local environment condition, both can use in conjunction, also can use wherein a kind of separately as cold and heat source.
Be described in detail the technology and the device structure of native system below in conjunction with accompanying drawing;
General structure:
Fig. 1 is the overall structure figure of native system; As seen from the figure; The overall frame for movement of native system is by air compression station 1, gas tank (air storage cavern) 2, heat exchanger 3, and trunk carrier pipe 5, terrain 6, region allocation pipe 7, pressure reduction control valve station 8, the terminal use of water body 4, band hot-swap feature control to adjust valve 9, air outlet 10, gas meter 11 etc. and partly form.These plant equipment constitute the overall technology structure of native system jointly with environment water 4 and terrain 6 as cold (heat) source.
1 air compression station 1:
Air compression station is the main equipment of native system.It is made up of air compressor unit, Large Storage Tanks gas tank 2 (air storage cavern), console, power supply, factory building etc.
2 heat exchangers 3
The function device that heat exchanger is welded by many small pipelines.Heat exchanger is to be placed in the environment water 3 when work, and environment water 4 is meant cistern, reservoir, river (on the river course), lake, municipal sewage treatment pond etc.They constitute the natural cooling source of native system.In northerly winter, when temperature significantly is lower than water temperature, also constitute primary heat source.
3 trunk carrier pipes 5 and region allocation pipe 7
Trunk carrier pipe 5 is the major function equipment of system with region allocation pipe 7, its task be reduce (rising) compressed air delivery of temperature to the user area.In this course of conveying, allow the interior compressed air of pipe further from terrain 6, absorb cold or heat (temperature relatively) simultaneously by tube wall.Make compressed-air actuated temperature further reduce (rising) to the level approaching with the temperature of terrain 6.
4 decompression controls and control valve station 8
Decompression control and control valve station are middle control and the air distributing devices from the region allocation pipe to the user terminal pipe network.Also be the terminal use service organization of system's management simultaneously.In technical management, it changes compressed-air actuated consumption figure according to the user regulates control to conveying capacity at any time.Be responsible for work such as region within the jurisdiction ownership and user's service, fee, maintenance, consulting simultaneously.Have functions such as operational management, technical maintenance and management, user's service.
5 terminal uses distribute pipe network
The terminal use distributes pipe network to be mounted in residential building, pipe network in the terminal buildings such as commercial affairs building, market, hotel, its task is to discharge to cold (heat) compressed air delivery of native system the room or the space at end user place, finally finishes the air conditioning service of system to the user.
6 user's control valves 9 and user's gauge table 11
Native system is the air capacity charge that consumes by the user.The user regulates with metering device and controls to adjust valve 9 and gas meter 11 with regard to the user who is mounted on the pipeline.Gas meter 11 is used for the air supply of metering user consumption, as the foundation of charge.Adjusting control valve 9 controls to adjust the size of the air supply of release voluntarily for users, by regulating the amount ratio of original air in compressed air and the room, to obtain desired preference temperature.
7 user terminal air outlets 10
User terminal air outlet 10 just is mounted in the compressed air air outlet of user room or control band, after compressed air comes out from air outlet, mix with the original air in being conditioned room or zone, because there are temperature difference in compressed air and original air, just reduced (or rising) after both mix and be conditioned room or regional temperature, finally realized predetermined air conditioning task.
Elaborate the course of work of system below, the duty of system is divided in the cooling of work in summer regulates and two kinds of the intensification adjustings of working in the winter time;
In summer, atmospheric air temperature is higher than water temperature and ground temperature;
In the winter time, atmospheric air temperature is lower than water temperature and ground temperature;
System is as follows in the course of work of the cooling adjustment state in summer;
1 air is inhaled into air compressor and is compressed, and is admitted to hold-up tank after the smaller volume and stores;
After pressure in 2 hold-up tanks reached the regulation atmospheric pressure value, compressed air began by the master control valve, entered the motion of pipeline heat exchanger and carried;
3 compressed air enter heat exchanger, carry out the heat release exchange by metal pipe-wall and natural water, and air themperature is reduced to and the essentially identical temperature of water temperature;
Compressed air after 4 coolings enters main pipe and the region allocation pipe is carried to the user area, and in this process, compressed air continues to carry out the heat release exchange by the tube wall of carrier pipe and terrain, reaches and the essentially identical temperature of terrain temperature;
5 compressed air enter pressure-reducing station, through entering terminal use's pipeline after the decompression automatically;
6 compressed air enter air outlet by user's gauge table and control valve, discharge to being conditioned the room then, finish with the original air in the room and mix, and by regulating the size of air output, just the temperature in room (zone) can be reduced to desired value.
So far, the air conditioning course of work of cooling pattern is finished.
In the winter time, system works is divided into two kinds of situations this moment again in the intensification mode of operation;
The one, water body is pure natural water, because temperature can raise after the air compression, if compressed-air actuated temperature is higher than water temperature, then need not through over-heat-exchanger, but directly enter main pipe by other pipe, and finish the heat exchanging process that absorbs heat to terrain by main pipe, carry to the user then.
The 2nd, if water body has adopted the heat energy utilization modes such as heat radiation waste water of geothermal water, enterprise, or temperature is extremely cold, and compressed-air actuated temperature is lower than water temperature, and then compressed air still passes through the water body heat exchanger, carry out heat absorption exchange process, and then carry to the user to water body.This and refrigeration work state are duplicate.
The switching valve of the conversion of these two different operating states before by the water body heat exchanger can be realized, and be very convenient and simple.
Come the adjusting implementation procedure of pictute invention below with a simple embodiment:
If the atmospheric air temperature of certain city's noon is 38 °, local river water temperature is 20 °, and underground 10 meters terrain temperature is 18 °, and the spatial volume in certain room is 100M 3, require the temperature in room is turned down 26 °.
Sending into temperature by native system to this room is 19 ° compressed air 65M 3, this 65M then 3Cryogenic air is extruded the room with original high temperature air, and extrusion capacity is 65M 3, old air capacity is 35% to 65% with the ratio of the Cryogenic air amount of newly sending into, mixed indoor air temperature is 25 95 °.
This adjustment process is regulated realization by the user voluntarily by control valve 9.
The advantage of invention technology
System of the present invention has extremely excellent energy-saving effect, and the significant advantage of safe and sanitary and environmental protection.
Compare with existing air-conditioning technical, the high-tech fractional energy savings of the technology of the present invention can add and use fractional energy savings and health energy-saving rate that total energy-saving effect can be up to more than 90% up to 80%.Below energy-saving effect is performed an analysis;
Technical energy saving effect aspect
The energy resource consumption of existing air conditioner mainly is used in blower fan (fan), freezes, heats this 3 aspects, and wherein blower fan (fan) accounts for the 10--20% of air conditioner total energy consumption, accounts for 80-90% and freeze and heat.
Contrast therewith, the energy resource consumption that native system only need be blown (being the energy resource consumption of air compressor machine) freezes and all take from the natural energy that the temperature difference contained of environment water and terrain and atmosphere with the energy that heats, and these two need not to consume the artificial energy source.Therefore just can save the energy of 80--90% from this characteristic.
The energy-conservation aspect of occupation mode
Existing central air conditioner system can't realize regulating as required accurately in use, normally no matter particular user has and do not have, and looks building user as a whole, completely air-supply.For example common central air-conditioning in use, can not be according to whether whether the someone decides this room to blow in certain room, send same big air quantity no matter client is 10 people or 2000 people in the market, so in use, just have very big wasting phenomenon.Sometimes, the energy waste that causes of this phenomenon will account for the quite big proportion of air conditioner energy consumption.
In contrast to this, the compressed air piping direct sending mode of native system, can be easy realize accurately and can regulate conveying easily, be included in the conveying as required that a family premises carries out controlling to adjust separately to each room with lateral to any room and zonule.Thereby improve effective regulation rate to greatest extent.Produce considerable use energy-saving effect.
Secondly, native system is because the advance and the practicality of technology, can adopt the mode (just the same) of user side meterage easily with the mode of running water and natural gas consumption metering, the user is in order to save the air-conditioning expense like this, the consumption that will consciously regulate as required, when having no talent in the room, will conscious valve-off, or it being adjusted to very little, the specific aim of Tiao Jieing is fine as required.This sample system just can be received considerable energy-saving effect on the motive power of the conscious cost of reducing expenses of user.
The energy-conservation aspect of the conversion of health indicator
We know, people require except the suitable requirement to temperature, humidity the air conditioning of work with living environment, also have one more importantly to require be the air freshness, promptly to the requirement of new wind: this is because except suitable temperature and temperature, people's eupnea also has airborne oxygen content, important health and comfortableness requirements such as waste gas content, particulate pollutant, bacterium and viral level.And existing air conditioner must adopt the circulated air mode in order not increase expending of the energy, promptly require to be conditioned zone or room must with outdoor atmospheric isolation, carry out closed cycle and regulate.This just causes the contradiction of healthy and comfortableness and energy consumption.And healthy and comfortableness be must the air quality index.Existing like this air-conditioning just can only be made balance by between, introduces the new wind of some in adjustment process, and this just causes the rapid increase of energy resource consumption.And even so, air conditioner surroundings still is considered to not meet the air ambient of health requirements.Particularly central air-conditioning is considered to serious pollution and disease public dissemination source (seeing the relevant document of the Ministry of Public Health), in all health and healthy data, all requires people not stay in the air conditioner surroundings for a long time.Most typical example is: during SARS took place, central air-conditioning was counted as dangerous infections channel, was forbidden to use.
In contrast, native system is a kind of whole fresh wind air-condition, can farthest, thoroughly satisfy the requirement of people to new wind, makes same good of the air quality of air conditioner surroundings and outside atmosphere environment.It is a kind of air conditioning environment that meets institute's unsoundness and healthy requirement fully.And this function does not consume the artificial energy source in addition because the refrigeration of native system or the energy that heats are to take from environment water and terrain, can need not to scruple energy consumption cost and unrestrictedly supplies new wind.Therefore providing the health that is higher than existing air-conditioning far away during with the comfort level index, the energy consumption of native system and ratio healthy, comfort level are that to have air-conditioning technical now too far behind to catch up.
If desired, the compressed-air actuated quality that native system even can realize flows to the user is higher than the target of ambient air quality, this is because native system adopts the work of pressure mode of movement, just can utilize pressure to realize filtration very simply, filter out harmful germ in the atmosphere and particle etc. air.And the machine chamber of the air compressor machine of system and conveyance conduit be to be in the hyperbar state when work, and most germs that is pernicious to people etc. can not survive in far above atmospheric hyperbaric environment this.Therefore the air compressor machine and the conveyance conduit of system have the natural function of killing pathogenic microorganisms.It is a kind of public air-conditioning system that has advanced physical disinfection efficacy, absolute safe and sanitary automatically that these functions make native system.
In addition, existing air-conditioning technical must use chemical substance as working media, and these chemical substances all are poisonous and hazardous to the people, also to environment particularly atmospheric environment substantial pollution is arranged.But also need consumes energy to produce (be the energy consumption of social industry's chain, it makes that the social actual consumption that has air-conditioning now is greater than its presentation power consumption values) earlier, could be for using.There are serious contaminated environment and highly energy-consuming defective.
And the working media of native system is exactly the normal air that the energy pure nature, inexhaustible, that need not the flower red cent is made in advance, without any pollution factor, safe and sanitary and the infringement of health and the difficult problem of serious environmental pollution that existing air-conditioning technical exists have thoroughly been solved to the people.Be to be competent at the harshest any safe and sanitary and the healthy and the most best green air conditioner technology of high environmental requirement.
Like this, if with technical energy saving, use energy-conservation, air health indicator energy consumption to require (converting for the energy consumption that new wind is provided is increased) be that evaluation criterion, the energy conservation rate of native system can reach more than the 85-95% that has the air conditioner energy resource consumption now by existing air-conditioning.This is a surprising progress.
Other advantage aspect
In others, native system also has plurality of advantages;
1 utilizes the cost advantage of valley power: native system can utilize the low ebb electricity price period production compressed air at night to store, thereby reduce operating cost greatly because the compressed air storage function is arranged.About about the 15-25% of crest segment electricity price, this is the technical-economic index of elevator system significantly greatly for various places low ebb electricity price at present, reduces user's consumer cost.
2 keep the visual dominance of City Building aesthetic appearance;
Facade design in each city all as smart as a new pin, but after the user moves in, each tame resident family all will install an air-conditioner, the air-conditioner outdoor unit of a large amount of various difformities, different outward appearances all is to be installed on the exterior wall carelessly, become scar very ugly on the building, heavy damage the aesthetic feeling of building, big very townscape.And native system adopts pressure to carry alternating temperature compressed air, only needs the very pipeline of registering one's residence of minor diameter, and employing and water supply pipe, inside concealment formula that natural gas line is the same are installed fully, and facade is had no effect, can perfect maintenance building attractive in appearance.Harmless city image.
3 save the construction cost and the space of central air-conditioning building:
The city palace uses central air-conditioning usually, and the unit of central air-conditioning and airduct are bulky, all will occupy sizable building space.The land price of inner city is high, and the construction cost of building is also just very high, so the cost ratio that central air-conditioning takes up room is quite big.And the small diameter pipeline of native system forced-draft (diameter is similar with water supply pipe to the natural gas of registering one's residence) occupation space is much smaller, can save appreciable construction cost and management, maintenance cost, save the water consuming cost of central air-conditioning down fully, also improved noise objective simultaneously.
Particularly for buildings such as subway, underground commerce facilities, because the underground space of these buildings is all come out with " money " heap, the space that native system is saved can significantly reduce the building cost of these facilities with considerable.
4 reduce urban heat land effect significantly;
No matter existing air-conditioning technical is unit air-conditioning or central air-conditioning, can only do air conditioning to the subenvironment of an appointment, disperses to surrounding enviroment and will regulate the used heat that produces.Though consequently reduced indoor temperature, outdoor environment temperature has raise.If regard a city as an integral body, and also regard whole air conditioners that use in this city as an integral device, then this air-conditioning equipment is with respect to this city, its group effect is one pure " a city heater ", the energy that this whole air-conditioning equipment consumed is all to transform for heat, heats to the city.Cause city atmospheric environment temperature significantly to raise, this promptly is famous urban heat land effect.Urban heat land effect has worsened urban environment, except the obvious reduction public's life and working environment quality, has also aggravated the demand to air conditioning greatly, forms a kind of serious vicious circle, also is the major reason that urban electric power consumption increases fast.
The large-scale promotion of native system then can fundamentally be reversed this process, because native system is with the unidirectional city of sending into of low temperature compressed air from the suburb, under the effect that pressure discharges, its effect is original hot-air to be extruded earlier be conditioned environment, and and then extrude the city, form the good result that the city continues cooling.
Embodiment
In the technical pattern of the present invention, all devices such as air compression station, conveyance conduit, gauge table and control valve are formed and technology all is an existing mature technology, and manufacturing and designing of its each part all is the group structure application of existing mature technology.Very simple.Therefore the pith of its enforcement is combining of using with the user.
System of the present invention is applicable to the application of general central air-conditioning fully.
But the best embodiment of system of the present invention is to build and be that the public provides service in the mode of large-scale city air-conditioning system.
This embodiment is exactly at the air compression station of surrounding city regional construction system and water body heat exchanger, then the trunk conveyance conduit is laid the district of going down town, arrive each user area through the region allocation pipe again, the last mode that enters each end user again through the pressure-reducing valve station.
The design of system, construction, equipment installation, operation, management etc. in concrete enforcement is built, with the city gas system be living basically.Its occupation mode is also basic identical.The product of supplying with customer consumption is exactly an alternating temperature compressed air.
When surrounding city is built a plurality of air compression station, can many conveying mains of auxiliary construction, with these pipelines networkings, sell alternating temperature compressed air then to resident and other type of user, do air conditioning for the user and use.Just as present city natural gas pipe network.This networking structure can provide better peak valley deliverability and supply stability.
Concrete implementation process is;
At first carry out the address choice of air compression station, the selection of address is best near river, lake, reservoir, municipal sewage treatment pond etc.
The design of air compression station is carried out after determining in the address;
