The invention discloses an energy-saving method for air conditioner. The air conditioner comprises an indoor heat exchanger, a variable frequency compressor, an outdoor heat exchanger and a throttling device, wherein many indoor heat exchangers are paralleling and each has at least an indoor fan. Likewise, many outdoor heat exchangers are paralleling and each has at least an outdoor fan. The controlling method comprises the control of the air conditioner operation refrigeration, the detection of the temperature deviation between the indoor environment temperature and the given temperature, the adjustment of the running frequency of the compressor according to the range of the temperature deviation, the adjustment of the the running frequency of the compressor, the indoor heat exchanger and the indoor fan when the temperature deviation reaches the preset range. The controlling method mentioned above has the advantage of being flexible in controlling air conditioner. That is, the demand of the room cooling or heating can be matched either with the cooling load of the air conditioner or the heating load of the air conditioner, thereby considerably improving the energy-saving effect of the air conditioner.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner energy-saving control method. Background technique [0002] At present, most of the air conditioners are traditionally set to operate in cooling mode in high temperature environment and in heating mode in low temperature environment, but for some special needs, the air conditioner needs to operate in cooling mode in low temperature condition. However, when the air conditioner is running in the low-temperature refrigeration mode and the operating load is small, the exhaust pressure of the compressor will be too small, resulting in insufficient pressure ratio of the compressor. If it is operated for a long time, the compressor may lack oil and affect the air conditioner. The stability of the system operation. For variable frequency compressors, the frequency of the compressor can be adjusted to adapt the compressor to the heat load of the room and impro...
