Hello everyone,

I have a problem in making air conditioner boundary condition.
I have a air conditioner with following specifications:
Cooloing capacity: 40 kW
Heating capacity: 26 kW
Evaporator air capacity: 4300 m3/h

I choose mass flow inlet with 1.46 kg/s(1,225*4300/3600).
But i need help on thermal side.

My first case:
Outer temperature: 0 C.
Initial(Inner) temperature of bus: 10 C

How can i set true condition with this specifications?

Fixed heat flux or fixed temperature?

If I use:
Power=mass flow rate * Cp * (T2-T1)
T2=[26000/(1005*1.46)]+10=27.7 C (temperature fixed at 27 C)
This is very simple approach. But Is it true?

Can you please help me?

Thank You
