A recently granted patent (Publication Number: US11884138B2) discloses a vehicle air conditioner with a unique configuration. The air conditioner includes an interior heat exchanger for air heating, a variable heat exchanger for condensing and evaporating refrigerant during air cooling and heating, and an evaporator for air cooling. The system operates in a refrigerant loop with a compressor, expansion devices, and various heat exchangers. Additionally, the air conditioner features a supply part that delivers air from the evaporator and condensate water to the variable heat exchanger. The design ensures efficient air conditioning within the vehicle.

Furthermore, the patent details the positioning and functionality of different components within the air conditioner. For instance, the variable heat exchanger module and air conditioning module are assembled together, with specific features like air inlets, control doors, and filters incorporated for optimal performance. The supply part includes an extension part for delivering condensate water and air, with fastening parts for secure attachment. The system also allows for selective supply of air passing through the interior heat exchanger to the variable heat exchanger, enhancing the overall heating and cooling process. Moreover, a control method is outlined for the vehicle air conditioner, involving the operation of a control door based on factors like exterior temperature and humidity levels, ensuring efficient and customized air conditioning for the vehicle occupants.
