Air Conditioning Trainer - Window Type:

Window air conditioner is becoming now a day’s necessity. The unit demonstrates the application of window air conditioner & evaluation of its performance. It consists of a small room to which a small air conditioner is connected the room is provided with a transparent front cover with a heater inside to simulate heat load in the room. Various measurements are provided so that performance of system that is COP of system, actual & theoretical cooling capacity of system & power consumption of unit with different load conditions.
