Dear friends,
I had discussion about this matter in a group yesterday. I have a question.

Suppose we have a 1 ph hermetic compressor.

1 - I was telling when suction pressure and discharge pressure are near to each other it means compression ratio is near to 1 and compressor will start better and easier (We have this matter at air-conditioning system compressor).

2 - Others insist on this matter when suction pressure is low, For example when we pump down compressor before off cycle, Compressor will start easier because compressor has not high load on suction and cylinder while wants to start.

I know while suction pressure decreases, Compressor load and working ampere would decreases, It is clear. But what about starting time ? In which case compressor would start easier ?

Which one is true ?

Sincerely yours.
