Description
The sewage source aircondition is a kind of heat pump that utilizes, and, can be widely used in closing on having and show water body significantly or the residential block of sewage water body is arranged or the room area of factory floor for the energy saver that the user provides refrigeration, heat supply by the sewage source heat exchanger.
Currently used headwaters heat pump normally utilize groundwater abstraction or water quality preferably surface water as the refrigeration, heat supply heat source body.The main feature of this technology is, utilizes the characteristics of deep phreatic water temperature higher (be generally tens to hundreds of degree centigrade), and to building heating, its advantage mainly is the COP value height of heat supply, compares with conventional heating system, and the characteristics of energy-conserving and environment-protective are arranged by heat pump.Its major defect is construction, operating cost higher (must build deep-well, the wasted work amount of water pump is bigger during operation); Since at present we to the circulation of deep phreatic water system, supply situation awareness seldom, the operation meeting of this system brings adverse effect to the underground water circulation system and the ecosystem; In addition, this system must recharge the underground water that extracts in running, and recharges underground water many more than the difficulty of extractions, be subjected to all multifactor influences, and the operation construction cost of recharging is higher; Moreover this system installs higher to water quality requirement in running.Above-mentioned reason causes when adopting underground water to make heat source body, and its construction, operating cost are higher, so limited the extensive implementation of existing apparatus.
Main purpose of the present utility model is exactly to provide a kind of surface water or sewage water body of adopting as the thermal source carrier of work system, is subjected to the heat source body water quality impact less, the device of construction, operating cost economy.
Overall structure of the present utility model as shown in Figure 1, it includes cold-producing medium cyclic part and water heat exchanging part, catalyst carrier cyclic part and water supply part, it is characterized in that wherein cold-producing medium cyclic part and water heat exchanging part, it is the compressor 3 that links to each other by with cross valve 4, place the sewage heat exchanger 2 of sewage wet well, common heat exchanger 1, and the check valve 6 that between sewage heat exchanger 2 and common heat exchanger 1, connects in due form, expansion valve 5, device for drying and filtering 8, liquid-sighting glass 9, fluid reservoir 7 is formed, and the catalyst carrier cyclic part includes the water circulating pump 10 that is connected with common heat exchanger 1 and general recirculated water supply part.
The course of work of whole device is divided into winter circulation, summer two processes that circulate:
Common heat exchanger 1 is as condenser in the winter circulation, after the compressed machine compression of cycle fluid in the work system, become the vapours of HTHP, its common heat exchanger 1 (condenser) of flowing through, carry out heat exchange with recirculated water, emit heat and provide hot water heating (general hot water temperature is about 45 ℃) for the user, simultaneously, the vapours condensation becomes liquid refrigerant, pass through then after the throttling action of expansion valve, change the liquid refrigerant (its temperature will be lower than the temperature of sewage) of low-temp low-pressure state into, the liquid refrigerant of this low-temp low-pressure carries out heat exchange with sewage through sewage heat exchanger 2 (evaporimeter) in wet well, absorb the heat in the sewage after temperature raise, working medium is evaporated to by the low-temp low-pressure liquid state and is inhaled into compressor behind the low-temp low-pressure gaseous state and compresses, according to this, working medium is carried out next working cycles process.After a such cyclic process, work system just can be converted into the Lowlevel thermal energy in the sewage high-grade heat energy that people can directly utilize.
In the circulation in summer, by the commutation effect of expansion valve and check valve, the flow direction of cycle fluid in work system is opposite with winter just, so sewage heat exchanger 2 is as condenser.When be collapsed into (temperature is higher than the temperature of sewage in summer) after the HTHP vapours of the compressed machine of cycle fluid, the sewage heat exchanger 2 (condenser) of flowing through carries out heat exchange with sewage in wet well, and temperature reduces, and working medium becomes liquid state by the gaseous state condensation.Afterwards, liquid refrigerant is (temperature is lower than the temperature of circulating water) after the throttling decrease temperature and pressure of expansion valve, enter common heat exchanger 1 (evaporimeter) and carry out heat exchange, absorb its heat and reduce its temperature, freeze for the user provides chilled water with recirculated water (catalyst carrier), simultaneously, cycle fluid raises because of absorbing the heat temperature, becomes gaseous state, is inhaled into compressor and compresses, according to this, working medium is carried out next cyclic process.In this process of refrigerastion, carry heat in the cold refrigerating medium absorption chamber, by the heat exchange of working medium cyclic process, the characteristic of utilizing the sewage summer temp to be lower than environment temperature enters it in sewage goes.
The utility model has reached the purpose of design.Adopt surface water characteristics cool in summer and warm in winter to be arranged, can well freeze, also saved the expense of making deep-well simultaneously for the user provides heat supply in winter, summer as the thermal source carrier water water body of work system.After then adopting sewage heat exchanger 2 of the present utility model in addition, overcome because the water quality of the most of water body of China is relatively poor, the water quality characteristics that contains a large amount of microorganisms, pollutant etc., thereby easily the heat exchanger of work system is caused adhere to, stop up, heat exchange efficiency and service life that rotten erosion simultaneously reduces heat exchanger, make the service behaviour coefficient of system, the problem of Technological Economy level reduction.Through technical research and field experiment, the main feature of this sewage heat exchanger is: 1. the heat exchanging part of heat exchanger is made up of the red copper light pipe, and compact conformation is corrosion-resistant, and hydraulic performance is good, is difficult for adhering to algae, microorganism or pollutant etc. in the sewage.2. by doing contrast test with other several Heat Conduction Materials, heat conductivility, the corrosion-resistant intensity of red copper in sewage all has remarkable advantages, so in same sewage working environment the time, the length of service of this heat exchanger is better than other common heat exchanger.3. this heat exchanger is made simply, is easy to processing, promotes the use of.4. the flow regime when current flow through heat exchanger is better, and the heat exchange of cycle fluid and sewage is abundant, and heat exchange efficiency is higher.Through field trial and improvement, the utility model item is with sewage source during as the heat-carrying water source, coefficient of performance of refrigerating can reach about 3.5 (promptly, the electric weight of consumption 1kw can obtain the cold about 3.5kw), heating performance coefficient can reach more than 4.3 (promptly, the electric weight of consumption 1kw can obtain the above heat of 4.3kw), has good energy-saving effect, compare with similar technology, this device can be built with contaminated water body as heat source body, operating cost is low, the adverse effect of having avoided groundwater abstraction to bring, the advantage that also has other similar technology simultaneously, that is, and environmental protection, convenient, economical, safety.
