A system for determining cleanliness of an air conditioner

Abstract

The present invention relates to a system (200) for determining cleanliness of an outdoor unit of an air conditioner. The system (200) comprising a plurality of detection means for obtaining an indoor wet bulb temperature, an outdoor ambient temperature and a condensing temperature; and a controller (220) having a computing module (222) and a determining module (224) for determining the cleanliness of the outdoor unit. A reference condensing temperature is determined based on the indoor wet bulb temperature and the outdoor ambient temperature as detected. The system (200) of the present invention determines that the outdoor unit is dirty when the condensing temperature is higher than the reference condensing temperature. [Figure 2]
