I have a sitiuation , I recevied one Air cooled Condensing unit of 1.5tr capacity at -1degC evaporating and 54 degc condensing . We feel that the condesor supplied is small . As the unit is tripping frequently in HP . we checked all the other parameter which are correct as per practise.
Can some one help us in giving following details

1. What should be the face surface area of condensor ? the condensor supplied has 3.7 sqft of face surface area.

2. How to decide on correct size of condensor
