A system for determining cleanliness of an air conditioner

Abstract

The present invention relates to a system (100) for determining cleanliness of an indoor unit of an air conditioner. The system (100) comprising a plurality of detection means for obtaining an indoor wet bulb temperature, an outdoor ambient temperature and an evaporating temperature; and a controller (130) having a computing module (132) and a determining module (134) for determining the cleanliness of the indoor unit. A reference evaporating temperature is determined using the indoor wet bulb temperature and the outdoor ambient temperature as obtained by the detection means. The system (100) of the present invention determines that the indoor unit is dirty when the evaporating temperature is lower than the reference evaporating temperature. [Figure 2]
