APPARATUS AND METHOD FOR DIAGNOSING PERFORMANCE OF AIR-CONDITIONING SYSTEMS

摘要

The present application reveals a method and an apparatus for diagnosing performance of an air-conditioning system. The method comprising the steps of determining a temperature differential between inlet and outlet temperatures of a condenser in the air-conditioning system; determining a temperature differential between inlet and outlet a temperature differential between inlet and outlet temperatures of an evaporator in the air-conditioning system; determining a temperature differential between ambient and vent temperatures in the air-conditioning systems; analyzing the differentials of the condenser, evaporator and ambient and vent temperatures; determining whether the air-conditioning system is properly functioning; and diagnosing performance of the air-conditioning system.
