The efficiency can also be calculated from.
WebCheck if the condenser fan motor is working when the compressor is on. Also, check for airflow restrictions that can cause this problem. The fan must come on when the compressor is on. If this does not happen, you must check the fan or motor and replace if defective. Check whether power is supplied to the fan motor and the connections are tight. WebAbstract. Where a cryogenic refrigerator cycle incorporates pistons operating between a plenum and the working volume and the plenum pressure is controlled to control the loading on the plenum side of the pistons, short time increased refrigerator capacity is obtained for cooldown by bleeding fluid from the plenum into the working volume.
