If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value with the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured to be maintained within the second temperature difference threshold value with the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the excessively low temperature of the heat exchanger of the indoor unit 100 is prevented.
When the air conditioner performs heating operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan of the indoor unit 100 according to the difference, and the higher the temperature of the heat exchanger tube is, the faster the fan rotation speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value from the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured within the second temperature difference threshold value from the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the heat exchanger of the indoor unit 100 is prevented.
The first temperature difference threshold and the second temperature difference threshold may be configured according to the specification and the use requirement of the heat exchanger of the indoor unit 100, for example, the first temperature difference threshold is set to plus or minus 3 degrees celsius, and the second temperature difference threshold is set to plus or minus 5 degrees celsius.
