[0053] see figure 2 The first embodiment of the energy-saving control method of the present invention is shown. The energy-saving control method is mainly applied to air conditioners, which includes the following steps:

[0054] Step S101, detecting the ambient temperature.

[0055] This step 101 detects the ambient temperature in real time, and the ambient temperature includes at least the indoor ambient temperature T1. Preferably, the ambient temperature in this embodiment also includes the outdoor ambient temperature T4.

[0056] Step S102 , judging whether the temperature difference between the indoor ambient temperature and the set temperature in the ambient temperature is less than a critical temperature.

[0057] This step S102 calculates the temperature difference between the indoor ambient temperature and the temperature set by the user. If the temperature difference is small, the small heating or cooling capacity can reach the set temperature, so it can run at a sm...

Abstract

The invention discloses an energy saving control method, an energy saving control system and an air conditioner. The energy saving control method includes detecting environmental temperatures; judging whether the difference between the indoor environmental temperature of the environmental temperatures and a set temperature is lower than a critical temperature or not; calling a corresponding highest energy efficiency comparison table according to a judgment result, and inquiring the optimal running frequency of a compressor in the corresponding highest energy efficiency comparison table; and controlling the compressor to run at the optimal running frequency. The optimal running frequency of the compressor is matched with the environmental temperatures. Accordingly, the environmental temperatures under different working conditions are detected, the difference between the indoor environmental temperature and the set temperature is compared to the critical temperature, and the corresponding highest energy efficiency comparison table is called according to a comparison result, the compressor is controlled to run at the optimal running frequency, the air conditioner keeps running in a state with the highest energy efficiency, and an energy saving effect of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an energy-saving control method and system and an air conditioner with the energy-saving control system. Background technique [0002] When the air conditioner is in cooling or heating operation, under a certain working condition, that is, under a certain ambient temperature, as the operating frequency of the compressor increases, the energy efficiency ratio of the air conditioner first increases and then decreases, and the energy efficiency The operating frequency corresponding to the highest point is the optimal operating frequency of the compressor. Under different working conditions, that is, under different ambient temperature conditions, the optimal operating frequency corresponding to the highest energy efficiency ratio is different, that is, different operating conditions correspond to different optimal operating frequencies. [0003] Such as figure 1 Shown is ...
