Abstract

The air conditioner of one image is provided with a compressor, an outdoor unit with Outdoor heat exchanger And electronic expansion valve, indoor unit With indoor heat exchanger, refrigerant pipe system connected outdoor unit and indoor unit And a control device that is structured to control the compressor And electronic expansion valve In air conditioners, a single HFC refrigerant is used as a refrigerant; The main thermistor is located in the middle of the machine's refrigerant pipe system. The heat exchanger inside the building that performs the cooling operation. And the thermistor was added Located at the inlet side of the refrigerant piping system for measuring the temperature of each position and a structured control device to maintain the level of the electronic expansion valve opening. On the opening side of consideration of the properties of a single HFC refrigerant, when the difference The auxiliary thermistor temperature, compared to the main thermistor, is equal to or greater than the correct reference value. Predetermined
