Determining the Cause of Higher-Than-Normal Discharge Pressure
Webaverage head pressure of a R-22 unit will run from 220 to 230 psig. If the unit cycles off on the high pressure switch, a problem exists. The number one reason for high head pressure is reduced heat transfer in the condenser. On a water cooled model check for internal scale build up or reduced water flow through the condenser, i.e. Web26 de fev. de 2015 · Since you have to compress gas to a high enough pressure to move heat into the outside air, the larger the cooler surface area the lower the head needs to be in relation to the outdoor ambient.
