Actual air-conditioning operation and its cycle
Dear all,
As many books and sources describe the refrigerant cycle at steady state for air-condition system, It really make me curious how the cycle change in the actual situation. So there are some questions, which it would be very kind of you if you could explain me how it actually take place :
1. According to some literatures, some refers to the condenser and evaporator temperature as fixed temperature, while some indicate it by varying it related to ambient condition. So, in actual situation, how is it?
2. Please correct me if i am wrong, as long as i am concerned, if the load is identical to that of design condition, the cycle should remain what it has been designed in the first place. And when the load is less than the design condition, the flow rate of refrigerant is reduced by inverter, et al. And if i am not wrong, the maximum compressor power is considered as constant.
3. In case of the actual condition is more extreme than what design condition is considered(Outdoor condition is extremely high, very large load), it would be very kind of you if you could explain what happen in the refrigerant cycle. Is it correct to assume that the heat gained from extreme conditions will raise the pressure or temperature in condenser and evaporator up?
Thank you in advance
Best regards

In a non.inverter driven chiller, the cooling capacity is either reduced with unloading or with cycling.

^^James, you need to use a Capital D not lower case d.
