reasons why the constant temperature and humidity test chamber does not cool

1. Introduction The phenomenon that liquid refrigerant and/or lubricating oil damage the suction valve plate when the gas is sucked into the cylinder of the compressor, and it is produced when the piston is compressed when the piston is close to the top dead center and is not quickly discharged during the exhaust process after entering the cylinder.
