Detailed description of the invention
Inventor is in enforcement the invention process, correlation technique is studied and is analyzed: heat pump application is in a lot of equipment or system, wherein representative, central air-conditioning, industrial refrigeration machine (system), domestic air conditioning and heat pump water heater etc.All there is the space that can improve or optimize in the heat pump in these equipment or system, makes introductions all round below for various device or system:
One, central air-conditioning
Conventional central air-conditioning generally comprises fan coil, chilled water circulating line, evaporimeter, expansion valve, compressor, condenser, cooling water circulation pipeline, cooling water circulating pump, cooling tower and water replanishing device.In the time of work, blower fan in fan coil by the airborne exchange heat in central air-conditioning place building in chilled water, chilled water obtains temperature rise after heat, chilled water after temperature rise is via the effect of chilled water circulating pump, flow to evaporimeter by chilled water pipeline, cold-producing medium in evaporimeter is under the control of expansion valve, heat in absorption refrigerating water evaporation, after being compressed by compressor, the refrigerant vapour that evaporation forms delivers to heat release condensation in condenser, with by exchange heat to cooling water, cooling water is under the driving of cooling water circulating pump, flow in cooling tower along cooling water pipeline, and intersperse among the surface of the filler in cooling tower, thereby cooling tower uses blower fan pectinid to impel cooling water steam raising that heat is taken in the outer atmosphere of described building.Water replanishing device is for filling to cooling tower the water evaporating.
The link of the exchange heat process need of this central air-conditioning is more, for example, take indoor heat to outdoor process and just comprise: indoor heat → fan coil → chilled water → chilled water circulating pump → evaporimeter → compressor → condenser → cooling water circulating pump → cooling tower → blower fan of cooling tower → cooling water steam → atmospheric environment.The energy consumption equipment wherein relating to is more, comprises fan coil, chilled water circulating pump, compressor, cooling water circulating pump and blower fan of cooling tower, causes central air-conditioning integral power consumption larger.And in exchange heat process, expend a large amount of running water resources.The energy and running water resource are all precious resources for day by day crowded city, and expensive cost, and the building of central air-conditioning is settled in a building, and the refrigeration expense of a year is millions of even up to ten million easily.And, in the circulation of cooling water, need regularly to add various bactericide, algicide and antisludging agent, not only increase operation cost, also because toxicity causes more serious pollution and harm to environment greatly.
In addition, facility more complicated and comprise more bulky equipment, for example cooling tower, the chilled water circulatory system, cooling water recirculation system and fan coil, increased central air-conditioning integral volume.And because cooling tower is generally placed on roof, the chilled water circulatory system and cooling water recirculation system are generally positioned at ground machine room lower, cooling water circulation pipeline that need to be longer and chilled water pipeline, these have all further increased central air-conditioning integral volume.
Moreover this central air-conditioning adopts cooling water circulation, has mass filler in cooling tower, filler has larger surface area, for carrying out heat of evaporation exchange with outside atmosphere.The continuous pectinid of blower fan of cooling tower, Feng Heshui contacts exchange, and now the dust in environment will constantly enter into cooling water, forms mud shape thing, causes equipment dirt.In the serious place of atmosphere pollution, one-year age can be from cleaning out the mud shape thing of tons of in equipment sometimes.Due to the continuous evaporation of water, the mineral matter enrichment in water, can fouling at the higher temperature of condenser, cleans difficulty; And the long-term and atmosphere close contact of cooling water, easily grows algae and even the mankind is belonged to breakneck Legionella.Due to above these factors, central air-conditioning needs frequent clean and maintenance, and cost is higher.
Two, industrial refrigeration machine
The composition of industrial refrigeration machine and above-mentioned central air-conditioning are similar, have essentially identical problem.
Three, domestic air conditioning
Present domestic air conditioning generally comprises off-premises station, indoor set, refrigerant line, drainpipe and remote controller etc., and wherein, described off-premises station comprises compressor, condenser and blower fan, and described indoor set contains expansion valve, evaporimeter, blower fan and control circuit.In the time of work, compressor compresses cold-producing medium, make cold-producing medium liquefaction via condenser effect, the cold-producing medium after liquefaction enters indoor set by refrigerant line, then heat absorption evaporation under the control of expansion valve, form refrigerant vapour, refrigerant vapour enters compressor via refrigerant line, and compressor compresses cold-producing medium makes cold-producing medium liquefaction via condenser effect,, go round and begin again.
Above-mentioned domestic air conditioning adopts split-type structural, and off-premises station must be placed in outdoor, and this structure at least exists following problem:
One, when extremely hot and sunlight is exposed to the sun at outdoor environment, can may cause condenser condenses difficulty, affects refrigerating efficiency.
Its two, bulky, no matter especially off-premises station, be to install or telephone-moving, all needs to seek help from professional.
For example, need professional to carry out work high above the ground with special stand when installation, and the connection of off-premises station and indoor set adopts dismountable form, the professional requirement of installation is very high.Domestic consumer cannot buy and use.If when moving or need to moving, also need professional to dismantle and move.
Its three, split-type structural determined indoor set and off-premises station between refrigerant tubing must adopt the structure of flexible connection, increased on the one hand the professional requirement of installing, on the other hand, cold-producing medium is easily revealed.
Four, heat pump water heater
Heat pump water heater is by being delivered in water and forming hot water after outdoor heat energy enrichment, for indoor.Be divided into air-source water heater, water source heat pump water heater etc.
Because being adopts heat pump techniques, Natural Gas Water Heater and the electric heater large with respect to power consumption have superiority aspect power consumption.But, owing to adopting outdoor heat energy, must carry out heat exchange with outdoor air or water, and the hot water producing is for indoor, just there is exchangeing problem of indoor and outdoor in this.Taking air-source water heater as example, current air-source water heater is generally divided into indoor set and off-premises station, and this structure there will be and the similar problem of above-mentioned split-type air conditioner, and due to the indoor stored hot water that needs, needs larger water tank, has increased equipment cost.In addition, off-premises station volume is larger, in less house type, be difficult to install, and if cancel indoor set, water tank is arranged on outdoor,, under the lower weather of outdoor temperature, heat loss is very large, affects result of use.
Carrying out after above-mentioned researching and analysing, inventor has proposed a kind of brand-new conception, and designs concrete implementation based on this conception, the problem existing to solve above-mentioned heat pump.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, the structured flowchart of the heat pump providing for one embodiment of the invention, as shown in the figure, described heat pump comprises compressor 11, cooler 12, regenerative apparatus 13, expansion gear 14, evaporimeter 15 and is such as connected above-mentioned all parts, so that the body 16 of cold-producing medium (freon, hydro carbons, ammonia or carbon dioxide etc.) circulation, and heat side liquid pipeline 17 and refrigeration side liquid pipeline 18, wherein:
Compressor 11 comprises compression unit 111, power transmission shaft 112 and motor 113, and motor 113 drives compression unit 111 to work by power transmission shaft 112.
The outlet and the entrance that heat side liquid pipeline 17 are communicated with the environment facies outside heat pump, and its main body has at least part to be placed in cooler 12 inside.
Outlet and the entrance of refrigeration side liquid pipeline 18 are communicated with the environment facies outside heat pump, and its main body has at least part to be placed in evaporimeter 15 inside.
The course of work of the heat pump that the present embodiment provides is as follows:
Motor 113, rotates and drive power transmission shaft 112 to rotate, thereby drive compression portion 111 is worked by power interface (not shown) from external power source obtains electric energy.When compression unit 111 is worked, (for example, temperature is 20 degree from the body 16 being communicated with, to suck cold-producing medium, pressure is 4bar), compress and become the refrigerant gas of high pressure-temperature (for example, temperature is 80 degree, pressure is 26bar), be transported to cooler 12 through body 16.
In cooler 12, for example, absorb heat from heating the fluid (air or water) that side liquid pipeline 17 flows through from the refrigerant gas of described HTHP, thereby the fluid temperature (F.T.) that makes to heat in side liquid pipeline 17 rises, form hot blast or hot water, simultaneously, the refrigerant gas temperature of described HTHP declines and progressively condenses into liquid state, forms the refrigerant liquid of high pressure.
The refrigerant liquid of the described high pressure regenerative apparatus 13 of flowing through, enters expansion gear 14, after pervaporation expands, forms the refrigerant gas of low-temp low-pressure, enters evaporimeter 15 through body 16.
In evaporimeter 15, fluid (for example air or water) in refrigeration side liquid pipeline 18 carries out heat exchange with the refrigerant gas of described low-temp low-pressure, make refrigerant vapour temperature rise, the fluid temperature (F.T.) in described refrigeration side liquid pipeline 18 declines simultaneously, forms cold wind or chilled water.
Described refrigerant vapour is from evaporimeter 15 flows out, enter regenerative apparatus 13 by body 16, carry out heat exchange with the refrigerant liquid of the above-mentioned high pressure flowing out from cooler 12, the temperature of the refrigerant liquid of described high pressure is reduced, described refrigerant vapour temperature rise simultaneously, and be inhaled into via body 16 in the compression unit 111 of described compressor 11.
In the time that needs heat, described in heat the outlet of side liquid pipeline 17 and entrance and be all positioned at indoorly, outlet and the entrance of described refrigeration side liquid pipeline 18 are all placed in outdoor.In the time that needs freeze, described in heat the outlet of side liquid pipeline 17 and entrance and be placed in outdoorly, outlet and the entrance of described refrigeration side liquid pipeline 18 are placed in indoor.
Outlet or the entrance of side liquid pipeline 17 can heated, outlet or the entrance of refrigeration side liquid pipeline 18 arrange blower fan (not shown in literary composition), work by blower fan, the fluid that makes to heat in side liquid pipeline 17 flows to its outlet along the entrance that heats side liquid pipeline 17, and, the fluid freezing in side liquid pipeline 18 is flowed to its outlet along the entrance of refrigeration side liquid pipeline 17.
Can find out, the heat pump that the present embodiment provides has been broken conventional thinking, by heat side liquid conduit and refrigeration side liquid conduit by space outerpace " extension " to heat pump inside, be equivalent to the material of exchange heat (air or water) to deliver to the inside of heat pump.This means in the heat pump that the present embodiment provides and need or not to be installed to outdoor going with the part of external environment heat exchange, can not need outdoor equipment (as the off-premises station of air-conditioning or Teat pump boiler), dwindled overall volume.And cold-producing medium can be sealed in heat pump inside, do not need to adopt the mode being flexibly connected, thereby reduced the risk of revealing.
In the present embodiment, regenerative apparatus 13 can adopt existing regenerator structure, example as shown in FIG., regenerator is enclosed construction, the part body wearing out from cooler 12 in body 16 is arranged in regenerative apparatus 13 with the part body wearing out from evaporimeter 15, carries out therein exchange heat.
Inventor is in the process of enforcement the invention, and the remaining temperature of the cold-producing medium that discovery is flowed out from cooler 12 is generally higher, and may not be pure liquid state, may contain gaseous refrigerant, and cooler 12 volumes is less, and this phenomenon is just more obvious.In addition, cold-producing medium (the being cryogenic gaseous) temperature flowing out from evaporimeter 15 is lower, same, and this phenomenon evaporimeter 15 volumes are less just more obvious.These two kinds of phenomenons all mean the waste of energy, even avoid this waste if can reduce, and can improve the operating efficiency of heat pump.
Therefore, inventor improves the structure of regenerative apparatus 13, at other embodiment of the present invention, for example, in the heat pump providing embodiment illustrated in fig. 2, in regenerative apparatus 13, there is entrance and exit, its entrance is connected and seals with the part body through cooler 12 in body 16, and its outlet is positioned under described entrance in vertical direction, connects and sealing with the part body that is connected expansion gear 14 in body 16.Thus, regenerative apparatus 13 forms the container with certain volume, the cold-producing medium (liquid or liquid and gaseous state mixes) flowing out from cooler 12 with storage, this cold-producing medium contacts with the part body wearing out from evaporimeter 15 in regenerative apparatus 13, and carry out heat exchange (being called backheat), the temperature of this cold-producing medium is lowered, being conducive to it fully liquefies, and the temperature of the cold-producing medium of the part body wearing out from the evaporimeter 15 of flowing through is improved, improve thus heat exchanger effectiveness.And, in regenerative apparatus 13, can also be placed with sieve particle 131, for the moisture of adsorption refrigerating agent, reduce the generation of even avoiding the stifled phenomenon of ice, be equivalent to " being dried " effect to cold-producing medium.Can find out, the regenerative apparatus 13 in the heat pump that the present embodiment provides can either " backheat ", also can " liquid storage ", also there is " being dried " function simultaneously, and therefore, this regenerative apparatus 13 can be called as the dry regenerator of liquid storage.
From heat pump overall structure, due to the existence of the dry regenerator of described liquid storage, compared with existing heat pump, in the situation that heat exchanger effectiveness is identical, do not need to possess cooler 12 and the evaporimeter 15 of larger volume, break to a certain extent the restriction of cooler 12 (or evaporimeter 15) volume to heat exchanger effectiveness, be conducive to the miniaturization of heat pump overall volume.
It should be noted that, above-mentioned sieve particle 131 belongs to existing material, herein it is not repeated.
Above-mentioned all embodiment can adopt expansion valve as described expansion gear 14, and the refrigerant liquid of the high pressure flowing out from regenerative apparatus 13 is through described expansion valve, and evaporation is expanded, and forms the refrigerant gas of low-temp low-pressure.Inventor is through research discovery, and the refrigerant liquid of high pressure, through described expansion valve, evaporates the kinetic energy producing that expands and is not utilized in expansion valve, has substantially been depleted, and belongs to the waste of energy.Therefore, the heat pump that other embodiment of the present invention provides adopts decompressor as expansion gear, and as shown in Figure 3, decompressor 14 is arranged in compressor 11, coaxial and lay respectively at the both sides of motor 113 with compression unit 111 with compression unit 111, be connected with described motor 113 by power transmission shaft 114.
The general knowledge of this area thinks, lower evaporimeter 15 temperature and higher cooler 12 temperature mean that compressor 11 has lower suction pressure and higher pressure at expulsion, and the power consumption of the compression unit 111 in compressor 11 will be along with increase.The ingenious decompressor that utilized of the present embodiment, and the motor 113 that itself and drive compression portion 111 work is coaxially arranged, utilizes the cold-producing medium power producing that expands.Concrete, the power that decompressor 14 relies on cold-producing medium to expand and produces can be used in motor 113 rotations, that is: the kinetic energy of high-pressure refrigerant is brought and is promoted decompressor 14 into play and does work in expansion process, thereby drive power transmission shaft 114 to rotate, and then help motor 113 to rotate, reduce the power consumption of motor.
Therefore,, under lower evaporimeter 15 temperature and higher cooler 12 temperature conditions, although the power consumption of compression unit 111 strengthens, the power that decompressor 14 produces has been offset a part of power consumption.Compared with prior art, the heat pump that the present embodiment provides can, in the situation that producing lower power consumption, provide greater efficiency.
Compression unit 111 and decompressor 14 can be with adopting vortex structure.
Inventor finds after studying and testing, compression unit 111 and decompressor 14 can be vortex structure, formed by quiet whirlpool dish and movable orbiting scroll, described quiet whirlpool dish and movable orbiting scroll close by involute vortex filament dirty separately, form enclosed cavity, thereby cavity dwindles or increases realization compression or expand in rotation process.But because movable orbiting scroll is not centrosymmetric, but there is certain eccentric throw, when therefore rotation, there will be vibration and then produce noise.Thus, inventor has done a little improvement to the structure of compressor 111 and decompressor 14, respectively extend one section of crankshaft handle from power transmission shaft 112 and power transmission shaft 114, by the moving turbine rotation of crankshaft handle drive compression portion 111 and decompressor 14, and, spill spin block has been installed, described spill spin block and crankshaft handle distribute as benchmark is 180 degree taking the center of power transmission shaft (power transmission shaft 112 and power transmission shaft 114), thereby single spin-echo when rotation, to offset the offset that eccentric motion was produced of crankshaft handle, reduce the vibration of compression unit 111 and decompressor 14 bodies, thereby reduced noise.
In order to prevent the rotation of movable orbiting scroll, can also adopt together with cross slide rail constrains in movable orbiting scroll and quiet whirlpool dish, so movable orbiting scroll only coils rounded track swing around quiet whirlpool but movable orbiting scroll does not carry out rotation.Avoid rotation consumed energy.
In the heat pump that the other embodiment of the present invention provides, the situation that is air for the fluid heating in side liquid pipeline 17, evaporimeter 15 has done particular design, in heat pump as shown in Figure 4, evaporimeter 15 inside are provided with defroster 151, and be provided with in bottom with the ponding of evaporimeter 15 internal communication and dredge passage 152, the outlet that this ponding is dredged passage 152 is placed in the porch that heats side liquid pipeline 17.The built-in position switch of defroster 151 and electric heater, in the time that the frost of evaporimeter 15 inside is tied to a certain extent, start electric heater work by position switch, carries out defrost.The condensed water forming after defrost is stored in evaporimeter 15 and dredges passage 152 from ponding and flows out, be inhaled into from heating the porch of side liquid pipeline 17 and (form negative pressure because fan action makes porch, thereby ponding is sucked), arrive cooler 12, because the temperature of cooler 12 is higher, this part condensed water is discharged from the outlet that heats side liquid pipeline 17 after evaporating.So, the problem of avoiding evaporimeter 15 to drip, and reduced the temperature of cooler 12, improve refrigerating capacity and Energy Efficiency Ratio.
It should be noted that, the above-mentioned mode that starts electric heater work by position switch can be manual operation, can be also by built-in control assembly automatic operation.Concrete, described position switch can be to be positioned in evaporimeter 15 the easily elasticity inductive head between frosting position and supporting surface, and in the time that frosting thickness exceedes certain size, contacting can be retracted and make to inductive head, and its resistance value and electric current can change.This variation will can be used as the signal of automatic electric-heating device.
