摘要： A heating, ventilation, and air conditioning system includes an evaporator configured to provide a working fluid in a gaseous state at a first temperature range and a first pressure, and a compressor downstream from the evaporator. The compressor is configured to provide the working fluid in the gaseous state at a second temperature range and a second pressure, and the second temperature range is greater than the first temperature range and the second pressure greater than the first pressure. The system includes a first thermoelectric generator arranged between the evaporator and the compressor. A first end of the first thermoelectric generator is configured to receive the working fluid from the evaporator, and a second end is configured to receive the working fluid from the compressor. The first thermoelectric generator is configured to generate electrical energy based on a temperature difference between the first end and the second end.

摘要： The present application relates to the technical field of air conditioners. Disclosed are a method and a device for controlling an air conditioner, an air conditioner and a storage medium. After the air conditioner is started and runs for a period of time, the gas phase side valve is controlled to open to switch the air conditioner to the phase separation refrigeration mode. In the phase separation refrigeration mode, the gaseous low-temperature refrigerant can be separated through the gas-liquid separation device, and be controlled to reach the heat exchanger. The refrigerant at the outlet of the condenser is exchanged heat again through the gaseous low-temperature refrigerant and the heat exchanger, thereby improving the subcooling degree of the refrigerant at the outlet of the condenser, in order to increase the cooling capacity of the air conditioner.
