Rack refrigeration experts this my first day work on rack system for refrigeration with vfd! The thing is ,I don’t understand why slow condenser fan speed increase liquid receiver level? I thought fast fan speed will increase receiver liquid level, slow fan speed will decrease liquid level? Can someone explain thanks

    Is there a head master valve on the condenser?

    Does it have a head master valve?
    Ambient temperature and Head pressure readings are also needed?
