@柯, How does the heat pump air conditioner work? Does it use thermal gradient (heat) to pump the air?
If you know the mathematical principle that governs the heat transfer (
) that causes the change in the air temperature over time, 
, then you can build the heat exchange system using basic blocks in Simulink and then verify your design against performance requirements.
