Description
Technical field
The utility model relates to a kind of solar heat pump installation, in particular, relates in particular to a kind of solar heat pump installation that can under the continuous low temperature environment, work.
Background technology
Heat pump techniques is a kind of new energy technology that development in recent years is got up, and is to transfer to heat from low-temperature heat source a kind of device of high temperature heat source through consuming a part of energy.The heat of transferring in the high temperature heat source comprises the energy of consumption and the heat that from low-temperature heat source, absorbs.
Air source hot pump water heater generally is made up of parts such as compressor, condenser, fluid reservoir, expansion valve, evaporimeters.Its operation principle is; Evaporimeter from airborne environment thermal energy draw heat with evaporation heat transfer working medium; Refrigerant vapor pressure and temperature after compressor compresses rises; When high-temperature vapour becomes liquid through forever cohering special ring pipe condenser condenses in water storage tank, the heat transferred that discharges the water in the air source heat pump water storage tank.Condensed heat-transfer working medium turns back to evaporimeter through expansion valve, and then is evaporated, so move in circles, thus the output of realization hot water.Adopting this technology can practice thrift a large amount of energy, can reach energy saving purposes, is the new energy technology of a kind of worth exploitation, popularization.But air source hot pump water heater has a very large shortcoming, is exactly cold district or high humility area in the winter time, and evaporimeter tends to serious frosting phenomenon occur, causes the heat pump can't operate as normal.
In order to address the above problem; Developed again afterwards a kind of with the heat pump of solar energy as the evaporimeter thermal source; Be exactly solar heat pump, it organically combines heat pump techniques and solar energy utilization technique, can improve solar thermal collector efficient and heat pump performance simultaneously.The heat that heat collector absorbs is as the low-temperature heat source of heat pump, but its all weather operations provides hot water or heat.A kind of solar air Teat pump boiler is disclosed like Chinese patent CN03150626.7; It is to be improved by direct expansion formula solar heat-pump water heater; Include a solar energy-air evaporimeter; An immersion condenser coil is at interior boiler, small-sized heat pump compressor and relevant refrigeration accessory reservoir thereof, heating power expansion valve etc.Its course of work is: cold-producing medium evaporates after in the solar heat-collection plate of solar energy-air evaporimeter, absorbing energy; The machine that is compressed sucks; The compression back flows into condensation in the condenser coil bottom the boiler; Discharge heat water, and condensed cold-producing medium flows back in the solar heat-collection plate through reservoir and heating power expansion valve and absorbs heat again, evaporates, circulation thus.Overcast and rainy, flow through the directly draw heat evaporation from air of cold-producing medium in the solar heat-collection plate, all the other whole operation cycle processes are constant.This solar air Teat pump boiler can effectively improve the heat pump heat supply performance, again can round-the-clock steady operation.
