Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a simple and efficient two-way supercooled air source heat pump. Background technique [0002] In the refrigeration / heating system, the subcooling degree of the condensed high-pressure liquid has an impact of about 20% on the refrigeration / heating capacity and efficiency. The cold and heat sources of the air source heat pump come from the air. The outstanding advantage is that the air is inexhaustible as a heat / cold source. Through the four-way valve to switch the circulation loop, the air source heat pump can both heat and cool. Even in a low temperature environment, the low-temperature air source heat pump adopts the technology of air injection to increase enthalpy, and the heating can be efficient, energy-saving and environmentally friendly; the disadvantage is that the current air source heat pump system usually only has a good one-way supercooling effect in the heating mo...
