TH61935B - Air conditioning unit - Google Patents

Abstract

DC60 (19/11/57) air conditioning unit, which can make intermittent operation. Of the compressor as little as possible. To provide a decrease in the efficiency of the air conditioning unit that occurs by intermittent operation and the variation in the indoor inlet temperature arising by intermittent operation. Can be reduced It was decided whether the deferral control of the thermal shutdown was allowed or not on the basis of The operating frequency of the current compressor when the thermal shutdown condition is satisfactory if the thermal shutdown delay control is judged to be allowed, the delay shutdown control. Heat where the lowest operating frequency in Compressor 1's operating frequency range is temporarily reduced within a range greater than or equal to the lowest operating frequency of Compressor 1 in continuous operation applications. If it is judged that the deferred shutdown control is not allowed, the thermal shutdown of the compressor stop 1 is performed, the air conditioning unit which can minimize the intermittent operation of the compressor. So that the decrease in the efficiency of the air conditioner unit that occurs by intermittent operation and the indoor inlet temperature variation that occurs by intermittent operation can be reduced. It was decided whether the deferral shutdown control was allowed on the basis of The operating frequency of the current compressor when the thermal shutdown condition is satisfactory, if the thermal shutdown delay control is judged to be allowed, the delay shutdown control. Heat where the lowest operating frequency in Compressor 1's operating frequency range is temporarily reduced within a range greater than or equal to the lowest operating frequency of Compressor 1 in continuous operation applications. If it is judged that deferred control of thermal shutdown is not permitted, thermal shutdown of compressor stop 1 is performed.

Claims (1)

1. A set of air conditioners which include Outdoor unit including compressor Indoor unit The inlet temperature sensing path that detects the indoor entrance temperature and the controller, which controls the frequency reduction of the compressor as required. Difference between indoor entrance temperature And the rated temperature drop at which the controller decides whether the deferred control of the heating opening time is allowed or not on the basis Of the current operating frequency of the compressor in cases where the indoor inlet temperature is less than or equal to the rated temperature of the thermal shutdown in the cooling mode or the indoor entrance temperature is greater than or equal to the rated shutdown temperature. Heat making model Heat to provide a satisfactory thermal shutdown condition. If the controller determines that the deferred shutdown control is allowed, the controller performs the thermal shutdown delay control where the operating frequency is lowest in the range. Compressor operation is temporarily reduced within a range greater than or equal to lesser operating frequency. The best compressors in use And the operation is continued and if the controller determines that the thermal shutdown delay control is not allowed, the controller acts to turn off the heat where the compressor is stopped.
