Problems solved by technology

In order to prevent the protection shutdown caused by high pressure, on the basis of the high pressure sensor, the frequency control of the air conditioner compressor is carried out according to the fixed high pressure limit, that is, when the high pressure of the air conditioner exceeds the fixed high pressure limit, the compressor is controlled. Frequency limitation and frequency reduction, so that the cooling capacity of the air conditioner cannot be fully utilized, and the cooling capacity decays rapidly

Abstract

The invention provides a high temperature refrigeration controlling method and an air conditioner. The high temperature refrigeration controlling method comprises the following steps that when a refrigeration mode is started, the outdoor environment temperature corresponding to the air conditioner is collected; according to the collected outdoor environment temperature, the current target high pressure limit value corresponding to the air conditioner is determined; and according to the collected real-time high pressure value and the determined target high pressure limit value, running frequency of a compressor of the air conditioner is adjusted and controlled until the the outdoor environment temperature change is collected. The current pressure limit which the air conditioner can bear canbe more accurately represented according to the target high pressure limit value obtained based on the outdoor environment temperature. High pressure shutdown protection is ensured not to occur, andunnecessary frequency falling is avoided. The decay rate of the refrigeration performance is improved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a high-temperature refrigeration control method and an air conditioner. Background technique [0002] Summer is the peak season for air conditioners, but the hot summer also poses challenges to the cooling performance of air conditioners. Usually, as the outdoor ambient temperature rises, the high pressure of the air conditioner will gradually increase. In order to prevent the protection shutdown caused by high pressure, on the basis of the high pressure sensor, the frequency control of the air conditioner compressor is carried out according to the fixed high pressure limit, that is, when the high pressure of the air conditioner exceeds the fixed high pressure limit, the compressor is controlled. Limiting and reducing the frequency, so that the cooling capacity of the air conditioner cannot be fully utilized, and the cooling capacity decays rapidly. Contents of the in...
