Title:
AIRCONDITIONING APPARATUS
Document Type and Number:
Japanese Patent JP3232755
Kind Code:
B2
Abstract:

PURPOSE: To improve reliability of a compressor by keeping the amount of air of an outdoor fan from lowering more than necessary.
CONSTITUTION: This apparatus is provided with an air quantity adjusting means 72 of an outdoor fan 26, an outdoor heat exchange sensor (Thc), an outside air temperature sensor (Tha) and a high pressure control switch (HPS2). A pressure judging means 73 is provided to output a high pressure signal when the pressure of a high pressure refrigerant is high and to output a low pressure signal when the pressure is low and an outside air temperature judging means 74 to output a high temperature signal when the temperature of the outside air is high and to output a low temperature signal when the temperature is low. In addition, an air quantity control means 75 is provided and the amount of air of the outdoor fan 26 is lowered sequentially so as to reach a low value corresponding to an outdoor heat exchange temperature based on the high temperature signal and the low temperature signal of the outside temperature judging means 14 each time the pressure judging means 73 outputs the high pressure signal while the amount of the air of the outdoor fan 26 is increased sequentially so as to reach 2 high value corresponding to the outdoor heat exchange temperature based on the high temperature signal and the low temperature signal of the outside temperature judging means 74 each time the pressure judging means 73 outputs the low pressure signal.
