Description

technical field [0001] The invention relates to a dual evaporator combined cooling and heating integrated machine, which belongs to the technical field of energy saving. Background technique [0002] Under the dual pressure of energy crisis and environmental crisis, energy conservation and emission reduction has become a topic of great concern. The heat pump is a high-efficiency energy-saving device based on the reverse Carnot cycle, which absorbs heat from a low-level heat source and transfers heat to a high-level heat source. As a form of air conditioning, heat pumps are widely used in building cold and heat sources. Its main components are evaporator, condenser, throttling device and compressor. When the air source heat pump is running in summer, a large amount of condensation heat is discharged to the environment through the condenser, which causes energy waste and environmental thermal pollution. From the point of view of energy saving, it is necessary to recover and...
