Air conditioner and control method for same

Abstract

The invention is applied to the technical field of air conditioners, provides an air conditioner, and aims to solve the problems of air conditioner performance attenuation and using effects reduction caused by the fact that air volume when an air conditioner is used for a region with low atmospheric pressure and air density is slightly smaller than actually required air volume in the prior art by virtue of linkage control of atmospheric pressure of a mounting site as well as a fan and a compressor. The air conditioner comprises a controller, an outdoor fan, a compressor and an atmospheric pressure feedback system for feeding back the atmospheric pressure of the mounting site, wherein the performance attenuation ratio of the air conditioner is calculated according to the atmospheric pressure of the mounting site, and the rotating speed of the outdoor fan and the output frequency of the compressor are corrected according to the performance attenuation ratio. The invention further provides a control method for the air conditioner. According to the air conditioner and the control method, the linkage control of the performance attenuation ratio as well as the wind speed of the outdoor fan and the output frequency of the compressor is realized according to the atmospheric pressure of the mounting site, so that the cooling and heating performance of the air conditioner running in a low-atmospheric pressure environment is prevented from being attenuated, and the air conditioner using effects of a user are improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a control method for the air conditioner. Background technique [0002] At present, the cooling and heating performance tests of air conditioners on the market are all measured under the premise of standard atmospheric pressure, without considering places with low air density such as plateau areas or basements and underground shopping malls. Ordinary air conditioners are installed in places with low air density due to the low air density. The air volume required to handle the same heat and humidity load is larger than that under standard atmospheric pressure. Since the fan speed of the air conditioner is not adaptively adjusted, the air volume is smaller than the actual air volume when the air conditioner handles the same heat and humidity load in the above-mentioned areas. At the same time, the low Air pressure also affects the boiling...

Problems solved by technology

[0003] The purpose of the present invention is to provide an air conditioner, which utilizes the linkage control of the atmospheric pressure of the installation site and the fan and compressor, aiming at solving the problem of the air volume ratio of the air conditioner in use in areas with low air pressure and low air density in the prior art. The air volume is too small, which leads to the attenuation of the performance of the air conditioner and the problem of reducing the user's use effect
