Superheat method using wet bulb return air temperature •determine the required superheat •measure the operating superheat •if the operating superheat is low…remove refrigerant In this video, i use a job check out sheet of complete system run data to determine what is wrong with the system using subcooling and superheat. Too much refrigerant the unit will use more energy to run.
Take a pressure reading of the suction line at the evaporator to get refrigerant saturation pressure=temperature.
In this video, i talk about which method should be use to verify charges of heat pumps or air conditioners. Heat pump charging in the winter season. Take a dry bulb temperature of the outdoor ambient air entering the condenser coil. Many systems are set to a lower speed at the factory to achieve a better seer rating.
