Description

Non-bearing type water source heat pump to exchange heat device

Technical field

The utility model relates to the structure of heat-exchange device, is specifically related to a kind of energy-efficient non-bearing type water source heat pump to exchange heat device that is applied in the earth-source hot-pump system.

Background technology

Nearest 20 years, in industrially developed country such as America and Europes, ground source heat pump technology was obtained development rapidly, has become the application technology of a maturation.Account for 40% of whole air-conditioning system at U.S.'s geothermal heat pump air-conditioning system; It is the energy-saving and environmental protection technology that U.S. government does one's utmost to promote; Up to the present the U.S. has installed 600,000, and the annual target of installing 400,000 of plan, can reduce by 1,000,000 tons of greenhouse gas emissions; Be equivalent to reduce the disposal of pollutants of 500,000 automobiles or plant trees 1,000,000 acres, 4.2 hundred million dollars of year saving energy expenditures; Countries such as Sweden, Switzerland, Austria, Germany mainly utilize earth source heat pump, be used for heating and the domestic hot-water is provided.But traditional heat pump mostly is the air-conditioning as refrigeration to be used, and reason is that leaving water temperature is too low when heating, and can only reach 45 degree, can not satisfy the requirement of the air-conditioner temperature in many places, more can not satisfy hot water temperature's requirement in place such as bathing.

Earth source heat pump is can be as the system of the low-temperature heat source of the cooling source of refrigeration in heat pump summer, winter heating heat supply with the source, ground; Heat pump is through consuming a small amount of high-grade energy; Rise to the high temperature level to heat by the low temperature level, thereby reach the purpose of heating, refrigeration or supply domestic water.It is used for substituting traditional pattern of carrying out air-conditioning, heating and heat supply with refrigeration machine and boiler, can effectively improve city atmospheric environment, and the saving high-grade energy is the new development direction that source, domestic ground can utilize.

Heat exchanger is the critical component of earth-source hot-pump system, and this parts solution of key technology becomes the key element that earth source heat pump popularizes.

Summary of the invention

The purpose of the utility model is: a kind of non-bearing type water source heat pump to exchange heat device is provided; The shell of this heat exchanger does not bear pressure, and the freon system is independent, is used for the geothermal heat pump air-conditioner unit; Freon and underground water are carried out energy exchange, thereby heat or freeze.

The technical scheme that the utility model technical solution problem is adopted is:

This heat exchanger comprises water exit elbow, blind flange, ring flange, adapter sleeve, housing, pull bar, deflection plate, heat exchange copper tube, separatory dish, remittance liquid dish and water supply connector; The two ends of housing are respectively through the adapter sleeve mounting flange; Blind flange is installed on the ring flange by bolt, nut, spring washer through sealing gasket, connects water exit elbow on the left end blind flange, connects water supply connector on the right-hand member blind flange; Separatory dish, the liquid dish that converges are separately fixed on the right-hand member blind flange; Deflection plate and heat exchange copper tube are installed in the housing, and one group of deflection plate incision is separated by to be arranged on the pull bar and is fixed by nut, and heat exchange copper tube passes deflection plate respectively; The import of heat exchange copper tube is connected with the separatory dish, and the outlet of heat exchange copper tube is connected with remittance liquid dish.

During work, freon gets in the heat exchange copper tube through separatory dish separatory, is converged from outlet by remittance liquid dish and flows out; Underground water gets into the housing, through deflection plate baffling and freon sufficient heat exchange from water supply connector.

The utlity model has following advantage:

1, the utility model heat exchanger applications is in earth-source hot-pump system, and energy consumption efficiency is high, and normal leaving water temperature is at 55 degree, and indoor air-conditioner temperature can reach more than 27 degree, can satisfy the requirement in places such as outdoor bathing place.

2, because the freon separatory dish and the liquid dish that converges are installed in heat exchanger, the condensing agent loop forms separately, makes housing not bear pressure.

3, because housing does not bear pressure, the utility model can adopt engineering plastics such as PVC-U, PP-R etc. to replace steel, improves the corrosion resistance of housing, alleviates the weight of heat exchanger, reduces product cost.

4, because heat exchanger shell does not bear pressure, flange arrangement is adopted at the heat exchanger two ends, and is easy for installation, is convenient to dismounting, is beneficial to cleaning, and long service life can also be taken out freon simultaneously.
