Abstract: PURPOSE:To reduce unnecessary defrosting operation when the ambient air temperature is high by inserting a correction resistor in parallel to an input resistor of defrosting periodic oscillation means of a defrosting controller into contact with a pressure switch for detecting the pressure of a freezing cycle to control the operation of an outdoor blower. CONSTITUTION:When an external air temperature is increased and a space heating ability is also increased, the pressure of a freezing cycle rises up, and a pressure switch 5 is turned OFF to stop an outdoor blower and to lower the heat absorbing amount and the space heating ability, and at the same time, a normally closed contact 5b is opened whereby the resultant resistance value of an input resistor 19 and a correction resistor 20 of oscillation means 18 of a defrosting controller 3 becomes large. Since the defrosting prohibition time is proportional to the product of the resultant resistance value and a capacitor 21, if the resultant resistance value becomes larger, the defrosting prohibiting time is set longer. Even when, regardless of the frosting amounts,the detected temperature of the outdoor heat exchanger is less than the set temperature, the time is elongated until the defrosting operation is started, and the frosting amount and defrosting synchronization are made optimum.

Abstract: PURPOSE:To prevent the deterioration of heating capacity, by a method wherein defrosting is effected without waiting for the arrival of the accumulating time of operation of a compressor at a predetermined value when the frosting speed of an outdoor heat exchanger is quick. CONSTITUTION:A first timer 7 totalizes the operating time of a compressor 1, however, when frosting speed is quick and the temperature of an outdoor heat exchanger has becomes lower than a predetermined value at a time T1' before the accumulating time of the operation of the compressor arrives at a predetermined value, a first temperature detecting circuit 9 outputs an H signal and a second timer 10 accumulates the time of continuation of the H signal. When an accumulated time or (t1+t2) has arrived at the predetermined value at the time point of T2', the second timer 10 outputs the H signal. When an atmospheric temperature is higher than the predetermined value, the second temperature detecting circuit 14 outputs the H signal. When two signals are inputted, an AND circuit 15 outputs the H signal and puts a relay 18 OFF by a driver 17 through an OR circuit 16, therefore, a four-way valve 2 is closed and defrosting is started.

Abstract: PURPOSE:To eliminate the defrosting operation not required where the outdoor temperature is high by short-circuiting the temperature detection element of a defrosting device at the contact point of a pressure switch which controls the operation of an outdoor blower by detecting the pressure of a refrigerating cycle. CONSTITUTION:The normally-open contact point 5a of a pressure switch controls the operation of an outdoor blower by detecting the pressure in a refrigeration cycle is connected in parallel with the temperature detection element 18 of a comparison means 22 which compares a set temperature of a defrosting control device 3 with a detected temperature. When the outdoor temperature is high, the temperature detection element of defrosting control device is short- circuited to cause the output of defrosting signal not to be outputted and eliminate unnecessary defrosting operation. Further a resistance 23 is for setting a temperature at which defrosting stops, and an IC control circuit 24 is provided with a timer that issues a defrosting prevention time t, and judgment means which issues defrosting signal with judgment of the output of the comparison means 22, and by the signal of the judgment means a relay coil 26 is turned on via a tansistor 25 and opens the contact point 4 to operate defrosting.
