View Full Version : Low suction temp vs. increased heat reject by condenser

Correct me if I am wrong:

If the suction temperature is below compressor recommendations the condenser will have to reject increased amounts of heat. As a result of low suction temp the mass flow rate is reduced (poor oil return aside) the less dense vapor entering the compressor will have an increase of superheat that will have to be rejected by the condenser.

Again correct me if I am wrong.. Just looking for confirmation on this or an understanding of something I am missing.

Load from evap will drop the power input will drop the total heat of rejection at condenser will drop, oil temp may rise.
