Description
Technical field
The present invention relates to a kind of cold and hot amount of utilizing heat pump techniques to extract in the seawater and be the method for space heating and air-conditioning, belong to energy technology field.
Background technology
The cold and hot amount that adopts heat pump techniques to extract in low-grade, the reproducible clean energy resource is space heating and air-conditioning, is one of effective way of building energy conservation reduction of discharging.These Cooling and Heat Source comprise: seawater, underground water, soil, municipal sewage or the like, their temperature winter is between 0 ~ 20 ℃, when its Cooling and Heat Source as heat pump is utilized, the primary energy of heat pump (coal, oil, natural gas) utilization ratio can reach 133% even higher, and energy-conservation amplitude can be more than 45%.But when utilizing these cold and hot energy, except that can only being used,, need to solve some key issues also because they self with suiting measures to local conditions.
The key issue of cold and heat sources of sea water heat pump is the conveying energy consumption of anticorrosion, anti-algae, anti-biological, antiscale and control water pump.Anticorrosion problem especially is difficult to solve, and when adopting special anticorrosion material integrity problem is arranged not only, and cost is very high, can not reach the purpose of applying, for example naval's copper, Alpaka, titanium alloy, special stainless steel or the like.Anti-algae, anti-biologically also be difficult to fine solution, also make the system process complexity usually, maintenance is big, the maintenance cost height.
Inquire into the methods of using now and mainly contain three kinds:
One, utilize the source pump of anti-seawater, its evaporimeter or condenser are made of anticorrosion material, and seawater directly enters source pump, digging well to get water by the sea.This mode mainly solves the etching problem of seawater, and its shortcoming is a poor reliability, can't guarantee that unit moves more than 15 years under no corrosion situation, in case erosion corrosion or clean and maintenance destruction etc. occur, unit may be scrapped, and also needs anti-biological grade for measure in addition, and initial cost is also higher.
Two, utilize the titanium sheet heat exchanger to carry out heat exchange earlier, the cold and hot amount of seawater is passed to clean water earlier, enter the ordinary hot pump assembly by clean water again, directly extracting seawater.This mode has mainly been protected source pump, and problem is concentrated on the titanium sheet heat exchanger, and its subject matter is that problem is cleaned in the obstruction of titanium sheet heat exchanger, and system effectiveness is low in addition, the conveying energy consumption height, and initial cost is higher, does not reach the purpose of applying.
Three, utilize the plastic coil heat exchange, plastic tube is immersed under the sea in modes such as spiral coils, flow in the pipe clean water and seawater to make heat exchange, clean water enters the ordinary hot pump assembly again.This mode is utilized the plastic tube heat exchange, has solved anticorrosion, anti-algae, anti-biological, antiscale problem, but plastic tube is immersed in the seashore so that the form of coil pipe is concentrated, and its shortcoming is: too tight between (1) tube and tube, heat exchange efficiency is low; (2) pipe ring is big around amount, and flow resistance is big in the pipe; (3) influence the marine site; (4) can only be several thousand square metres building small-scale application.
Chinese patent " CN1442658A " discloses " a kind of source pump of utilizing source of seawater ", Chinese patent " CN101158523A " and discloses " sea water ground energy heat pump system and extract the method for sea water ground energy " etc. and all belong to first kind or the second way.
Chinese patent " CN201081572Y " discloses " heat exchanger and heat exchanger assembly ", Chinese patent " CN201014844Y " discloses " sea water source heat pump aircondition " etc. and belonged to the third mode.
The scientific paper that also has some patent documentations and publish, all related to the application problem of seawater Cooling and Heat Source, but all not yet in effect or solve problems such as the conveying energy consumption of anticorrosion, anti-algae, anti-biological, antiscale, control water pump and large-scale promotion application well.
Summary of the invention

The application process of the cold and heat sources of sea water heat pump that the present invention proposes, as shown in Figure 1, it is made up of following steps: (one) comes and goes long straight the laying with many plastic tubes along the deep-sea direction, plastic tube length is 50 to 600 meters, several plastic tubes wherein form the unit tube bank with different forms, its intake-outlet by minute, collector pipe is together in parallel, in the unit tube bank, disperse to add weight, the unit tube bank is sunken to the seabed, the unit tube bank is restrained with unit and is together in parallel by pipeline, and medium is clean water or contains antifreeze in the pipe
The aqueous solution of liquid, medium come and go in pipe and absorb the cold and hot amount of seawater in the flow process, by the medium transport pipeline cold and hot amount are passed to source pump again; (2) the cold and hot amount transmission and the conversion of source pump inner evaporator and condenser, evaporimeter absorbs low-grade heat, and condenser discharges the high bit heat; (3) terminal hot and cold water enters the condenser or the evaporimeter of source pump, the cold and hot amount in evaporimeter or the condenser is taken away, and be passed to terminal heat dissipation equipment.
Operation logic is: medium is that the clean water or the aqueous solution that contains anti-icing fluid enter long straight round being layed in the heat exchange plastic tube in seabed, in pipe, come and go and absorb the cold and hot amount of remote seawater in the flow process, by feed-line cold and hot amount is passed to source pump again, the cold and hot amount transmission and the conversion of source pump inner evaporator and condenser, evaporimeter absorbs low-grade heat, condenser discharges the high bit heat, terminal hot and cold water enters the condenser or the evaporimeter of source pump, cold and hot amount in evaporimeter or the condenser is taken away, and be passed to terminal heat dissipation equipment.
Application process of the present invention has following characteristics and beneficial effect thereof:
One, utilizes plastic tube to form the tube bank heat exchange, avoided key issues such as anticorrosion, the anti-algae of source of seawater, anti-biological, antiscale, also improved the reliability of system, and reduced the initial cost of system to greatest extent;
Two, long straight the coming and going of plastic tube bundle laid, can extract the cold and hot amount of remote seawater, can realize extracting the seawater Lowlevel thermal energy on a large scale along the deep-sea direction to the deep-sea;
Three, after long straight round laying of plastic tube bundle, tube pitch is sparse relatively, and the heat transfer outside a tube coefficient is big, has not only improved heat transfer efficiency, and also owing to be long straight state, flow resistance in having reduced to manage can reduce pump energy consumption;
Four, plastic tube bundle long straight come and go to lay be sunken to the seabed, the seabed ocean temperature is cool in summer and warm in winter with respect to seawater surface temperature, has improved the efficient of heat pump, in addition, does not also influence the attractive in appearance and boats and ships circulation in marine site as far as possible after being sunken to the seabed;
Five, utilize long straight the coming and going of plastic tube bundle to lay, owing to can extract the cold and hot amount of remote seawater along the deep-sea direction, the oceanic area that the unit building needs is less, and engineering can be implemented on a large scale.
