Abstract

PURPOSE: To save energy resources, by utilizing temperature for cooling purpose until re-evaporation of condensed dews in the evaporator starts after the termination of the compressor operation.
CONSTITUTION: By switching ON a switch 22, a compressor 1, outdoor fan 5 and indoor fan 6 are respectively driven. As the indoor temperature is gradually lowered to an off-point, a temperature detector 8 detects it and an output thereof is supplied to a control element 7. The control element 7 suspends the operation of the compressor 1 through a relay coil 25 and a relay contact 27. On the other hand, the indoor fan 6 keeps revolving while a comparing element 9 shows a relation of t1<t2, where t1 being the temperature of an evaporator 4 detected by a temperature detector 10 and t2 being that of condensed dews 12 detected by a temperature detector 11. When the comparison element 9 shows that t1=t2, the fan is stopped by the control element 7, relay coil 26 and relay contact 28.
