Air conditioner and control method thereof

Abstract

The invention discloses an air conditioner and a control method thereof. The control method comprises the following steps that S10, the air conditioner is controlled to operate; S20, whether the air conditioner meets a first energy efficiency test condition and a second energy efficiency test condition at the same time or not is judged, the first energy efficiency test condition comprises that the air conditioner is in a preset mode, the set temperature of the air conditioner is the target energy efficiency test temperature, and the air speed of the air conditioner is in a high-wind mode; the second energy efficiency test condition comprises that the current indoor environment temperature Tin1 and the indoor environment temperature preset value Tin1set meet the condition that |Tin1-Tin1set| is smaller than or equal to Tin0, the current outdoor environment temperature Tout1 and the outdoor environment temperature preset value Tout1set meet the condition that |Tout1-Tout1set| is smaller than or equal to Tout0, Tin0 is the indoor environment temperature fault-tolerant return difference, and Tout0 is the outdoor environment temperature fault-tolerant return difference; and S30, when the air conditioner meets the first energy efficiency test condition and the second energy efficiency test condition at the same time, the air conditioner is controlled to enter an energy efficiency test state. According to the control method, trouble and labor are saved, and the efficiency of the energy efficiency test experiment of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] In related technologies, manual control is usually adopted, for example, manual operation is performed on the panel keys of the air conditioner, the keys of the remote control, etc., so that the air conditioner enters the energy efficiency test running state. In the energy efficiency test running state, the air conditioner operates under specific energy efficiency test conditions, for example, the air conditioner operates at the set target temperature, the air conditioner’s compressor operates at the set target frequency, and the air conditioner’s fan operates at the set Run at the target wind speed to test whether the air conditioner can achieve the desired energy efficiency under the energy efficiency test conditions. Once the energy efficiency test working condition is changed, manual re-o...

AI Technical Summary

Problems solved by technology

It can be seen that the above-mentioned manual control method is time-consuming and labor-intensive.

Therefore, the air conditioner enters the energy efficiency test operation state by manual control, resulting in low efficiency of the energy efficiency test experiment.

[0003] In addition, some regions such as North America have put forward new standards for the energy efficiency test of air conditioners, requiring that the air conditioner can automatically enter the energy efficiency test experiment in the normal free running mode, so the existing manual control method can no longer meet the requirements.
