PURPOSE:To prevent dew-condensation by judging large frosting amount of a cooler if a damper exceeds its continuous 'opening' time with respect to a set value, and operating an evaporation proceeding blower in synchronization with the rotation of a rotary compressor up to next defrosting after next defrosting from that time. CONSTITUTION:An evaporation controller 24 has a timer 25, an AND circuit 26, a transistor 27, and a relay coil 28, and the output of a terminal (a) of a defrosting controller 16 is input to the circuit 26 and the timer 25. The output of a terminal (b) of the controller 16 is input to the timer 25. The timer 25 continuously generates an 'H' signal up to the end of next defrosting after next defrosting to the circuit 26 when the damper 40 of a motor driven damper 28 is arrived at predetermined continuous 'opening' time. The output of the circuit 26 becomes an 'H' signal according to the 'H' signal from the timer 25 and an 'H' signal (i.e., during operation of a rotary compressor 6) from the controller 16, and an evaporation proceeding blower 30 is operated. |
