Abstract

The invention discloses an air conditioner. The air conditioner comprises an outdoor unit, wherein the outdoor unit comprises an electric heating belt for heating compressor lubricating oil and evaporating a liquid-state refrigerant in lubricating oil, an outdoor fan for conveying outdoor air to an outdoor heat exchanger, and a control part which is configured to obtain a gas exhaust temperature of the compressor, an outdoor coiled tube temperature and an outdoor environment temperature, determine gas exhaust superheat degree according to the gas exhaust temperature and the outdoor coiled tubetemperature while the air conditioner is detected to enter a low-temperature refrigerating control mode, control a working state of the electric heating belt according to the gas exhaust superheat degree, calculate temperature difference between the outdoor coiled tube temperature and outdoor environment temperature, and control rotation speed of an outdoor fan according to the temperature difference. According to the air conditioner disclosed by the invention, low-temperature refrigerating control can be realized by controlling an operation state of the outdoor fan and the electric heating belt, so that high-low pressure of an air conditioner system can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner which performs low-temperature cooling control by controlling the operating states of an outdoor fan and an electric heating belt. Background technique [0002] At present, with people's continuous pursuit of healthy life, places such as gymnasiums and bath centers continue to increase. In winter, the temperature and humidity of the indoor environment in these places will still be high, and users still have the ability to cool and dehumidify in this environment. need. In the actual use of the air conditioner, there are still the following problems: when the air conditioner is performing cooling and dehumidification operations in an outdoor low-temperature environment, the air conditioner operates in the low-temperature cooling mode. There are problems such as hydraulic compression and oil return difficulties, which affect the reliability of air condit...
