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 |
