The EZHS series back-mounted air conditioning unit is suitable for double-decker or battery electric vehicles. The advantages of the back-mounted air conditioning unit are large cooling capacity, small size, easy maintenance, upper and lower air supply, and uniform distribution. Compared with the roof-mounted air conditioner and built-in air conditioner, the back-mounted air conditioner offers a longer air supply distance and greater wind pressure. This design effectively addresses the cooling and heating needs of the entire vehicle, particularly in the back, while also being easy to maintain.
- Cooling working principle
-
At cooling mode, the liquid refrigerant absorbs heat and vaporizes, becoming LP, LT steam, and goes into compressor, and gets compressed into HT, HP gas, then moves through 4 way valve, then into condenser to lose heat, it becomes mid pressure, LT liquid, then throttled by expansion valve, loses pressure, then goes into evaporator to vaporize. Such loop goes on and on.
- Heating working principle
-
At heating mode, the compressed HP, HT gas refrigerant goes into bus evaporator to release heat, becoming mid pressure LT liquid, then throttled by expansion valve, becoming LT, LP liquid and vaporizes in the condenser to change into gas refrigerant, and goes into compressor again. The loop continues.
