Abstract
PURPOSE: To prevent abnormal phenomenon at the starting time by controlling the starting of a capacity variable compressor in response to the temperature.
CONSTITUTION: Temperatures of a pole-variable capacity-variable compressor 1 provided with a bipolar coil 1a and a tetrapolar coil 1b are detected. It is provided with a temperature detector 6 composed of a thermostat, etc. and its firm open contact 6a is connected with relays 2W4. Thereby, if a power switch 8 is turned on, a relay 7 is put into operation, the air conditioner is brought into motion. When the temperature of the compressor 1 is under the assigned one as it has not been used for a long time, a contact 6a is open, current is not applied at a relay 4, a contact 4b is closed, a relay 3 works so that the compressor starts through a low capacity tetrapole. Therefore, the falling speed of pressure is slower than in a large capacity bipolar operation, the forming phenomenon is weaker there and damages of valves, etc. due to the compressed liquid can be avoided.
