    Cooling:
    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:
    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. 

    L/HP: low/high pressure

    L/HT: low/high temperature
