Abstract:
1. A method of monitoring operation of a refrigerant-cycle system, the method comprising: measuring operating characteristics of the refrigerant-cycle system using a plurality of sensors, the refrigerant-cycle system including a condenser unit and an evaporator unit, the condenser unit including a condenser and a compressor, and the evaporator unit including an evaporator and a fan; using a processing system, receiving the measurements from the plurality of sensors and outputting data regarding operation of the refrigerant-cycle system to a remote monitoring system; calculating an efficiency of the refrigerant-cycle system based on the data; determining an expected efficiency of the refrigerant-cycle system; and based on a comparison of the calculated efficiency of the refrigerant-cycle system with the expected efficiency of the refrigerant-cycle system, selectively performing at least one of:
