PURPOSE: To control the capacity of an air conditioner according to the sensing results of an outdoor temp. and the weather by a method wherein a temp. sensing thermostat is installed to sense the temp. of an outer case at the outdoor side and the revolving speed of an outdoor motor for air blasting is controlled by this thermostat.
CONSTITUTION: A temp. sensing thermostat 10 is installed on an outer case 11 at the outdoor side to sense the temp. of the case. When the weather is fine and there is much radiation heat, the temp. of the case 11 becomes very high due to the exposure to the direct rays of the sun and then the quantity of air blasting is increased by raising up the revolving speed of an outdoor motor 6 for air blasting and the space cooling capacity of an air conditioner is increased by raising up the capacity of an outdoor heat exchanger 4. When the weather is cloudy or rainy and there is little radiation heat and the capacity increase of the conditioner is not necessary, the temp. of the thermostat 10 does not rise up and the revolving speed of the motor 6 is kept low. Thereby, the excess operating power of a compressor is not consumed and an increase in noise due to the raised speed of an outdoor blower 5 is able to be prevented.
