Abstract: An air-conditioner comprises a refrigerating circuit having a compressor, a condenser, an expansion device and an evaporator which are connected by suitable refrigerant conduits. An electric current path for making a current flow through the compressor includes an AC power source, to which a current transformer is coupled, and an output of the current transformer is converted into a DC voltage which is then given as a (+) input of a comparator. A reference voltage is given to a (-) input of the comparator. When the DC voltage exceeds the reference voltage of the comparator, the high level is outputted from the comparator. When the high-level output from the comparator persists for three seconds, the compressor is stopped forcedly and a three-minute timer is turned on. After a lapse of three minutes, the flow of the current through the current path of the compressor is resumed. Thereby, a lightly locked state is removed. If the output of the comparator still remains at the high level when the energizing is resumed, the compressor is put in the stopped state again. When such stopping and resuming of energizing of the compressor are repeated four times, the energizing of the compressor is stopped assuming that the compressor is in a heavily locked state.

Abstract: An air conditioner comprises a control portion and a refrigeration system wherein a compressor, a condenser, an expansion device and an evaporator are connected in a refrigerant flow relationship. The control portion compares the temperature measured by a room temperature sensor with the temperature set by a temperature setting switch. For heating, the compressor is stopped when the room temperature rises higher than the set temperature, and for cooling, the compressor is stopped when the room temperature falls lower than the set temperature. A special switch is installed in the control portion, and when this switch is operated, responsively the range of the temperature set by the temperature setting switch is changed. More specifically, when the switch is operated at heating the control portion lowers the upper limit of the temperature set by the temperature setting switch and at cooling, the lower limit of the temperature is heightened by the control portion. Thereby the capacity of heating or cooling of the air conditioner is reduced, therefore an over cooling at cooling and an over heating at heating can be prevented.
