<p>The present invention provides a surface temperature estimation device which is suitable for estimating the surface temperature of a heat exchanger with condensate generation, a surface temperature estimation method and a condensate determination device. A control device (19) estimates surface temperature of a heat exchanger (121a) according to the temperature of refrigerant which is supplied by an outer unit (13) and is measured by an outlet temperature sensor (17) and the temperature that is measured by a surface temperature sensor configured on the surface of the heat exchanger (121a). Therefore, the surface temperature of the heat exchanger which is suitable for forecasting condensate generation can be obtained. Furthermore, the obtained value is compared with an indoor dew point temperature which is measured by indoor sensors (15a-15c) for determining whether condensate occurs on the heat exchangers (121a-121c) of cold beams (12a-12c). Therefore, the result of the surface temperature estimation device can forecast condensate more accurately.</p> |
