Air cooler of air conditioner

Abstract

Abstract PURPOSE: To obtain a sufficient cooling effect by extending the driving time of the cooler upon starting of the cooling, depending upon its cooling state, and delaying the start of operation an electrically driven blower up to the cooling of the cooler. CONSTITUTION: When the temperature of an evaporator 5 is higher than a predetermined value at a point in time when a switch 14 is turned on and a normally opened relay 16 is closed, thermostats 4 and 9 are in an ON state, and an electromagnetic clutch 3 is supplied with power and the temperature of the evaporator 5 is lowered by the operation of a freezing cycle. On the other hand, when an electrically driven blower 12 is in a stopped state, and the temperature of the evaporator 5 reaches a certain temperature, the electromagntic clutch 3 is deenergized, and the freezing cycle is stopped. Further, power is supplied to the electrically driven blower 12, and the operation thereof is started at a predetermined rotational speed. The thermostats 4 and 9 have hysteresis characteristics, whereby the driving time of the evaporator 5 upon starting of the cooling is extended depending upon the cooling state.
