Abstract

The invention discloses an air-conditioner energy saving control method, and belongs to the technical field of air-conditioners. An air-conditioner comprises indoor heat exchangers, an inverter compressor, outdoor heat exchangers and a throttling gear; the multiple indoor heat exchangers are connected in parallel, each indoor heat exchanger is correspondingly provided with at least one indoor draught fan, the multiple outdoor heat exchangers are arranged in parallel, and each outdoor heat exchanger is correspondingly provided with at least one outdoor draught fan. The control method includes the steps that the outdoor environment temperature is detected; the running frequency of the compressor, the indoor heat exchangers, the indoor draught fans, the outdoor heat exchangers and the outdoor draught fans are adjusted according to the scope of the outdoor environment temperature; and when the outdoor environment temperature reaches a preset scope, the temperature difference of the indoor environment temperature and the outdoor environment temperature is detected, and the running frequency of the compressor, the indoor heat exchangers, the indoor draught fans, the outdoor heat exchangers and the outdoor draught fans are adjusted according to the temperature difference. By means of the above control method, control over the air-conditioner is more flexible and convenient, and the energy-saving effect of work of the air-conditioner is improved more efficiently.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, and in particular to an energy-saving control method for air conditioners. Background technique [0002] At present, most of the traditional use of air conditioners is set to operate in a cooling mode in a high temperature environment and a heating mode in a low temperature environment, but for some special needs, the air conditioner needs to operate in a cooling mode under low temperature conditions. When the air conditioner is running in low temperature cooling mode and the operating load is small, the discharge pressure of the compressor will be too small, resulting in insufficient compressor pressure ratio. Long-term operation may cause the compressor to run out of oil and affect the air conditioner. The stability of the system operation. For inverter compressors, the frequency of the compressor can be adjusted to adapt the compressor to the thermal load of the room and increase the serv...
