technical field

The invention relates to the technical field of energy-saving and environmental protection equipment, in particular to a special heat exchange device for a solar energy lifting heat pump.

Background technique

A heat pump is a high-efficiency energy-saving device that makes full use of low-grade thermal energy. Heat can spontaneously transfer from a hot object to a cold object, but not in the opposite direction spontaneously. The working principle of a heat pump is a mechanical device that forces heat to flow from a low temperature object to a high temperature object in a reverse cycle. Heat energy can be utilized to achieve energy saving purposes, and the popularity of heat pumps will also be dramatically improved. Ground source heat pump is a kind of heat pump, which uses the earth or water as a cold and heat source to cool buildings in winter and cool in summer. Use very little electricity to maintain the desired temperature in the room. In winter, 1 kilowatt of electricity will send 4-5 kilowatts of heat from the soil or water source into the room.
