Problems solved by technology

Therefore, in the actual working process, there is a part of the hot air discharged from the air outlet through the air duct between the installation station wall and the shell and is re-inhaled into the outdoor unit by the air return port, which causes the ambient temperature of the air conditioner to rise and the cooling effect to deteriorate. , affect user experience, and increase energy consumption at the same time, which does not meet the national energy conservation and emission reduction requirements

Abstract

The invention discloses an outdoor unit of an air conditioner and a control method for preventing return air. The outdoor unit comprises a shell (1), wherein an air outlet (2) is formed in the front surface of the shell (1) and covers with a mesh enclosure; the shell (1) is also provided with a stretchable bamboo joint type air outlet cover (4), and the rear end of the air outlet cover (4) is communicated with the air outlet (2) and is sealed. The key of the control method lies in controlling the spread degree of the air outlet cover (4) according to the temperature difference between exhaust air temperature and return air temperature. The outdoor unit and the control method can prevent air conditioning hot air on an installation station from sucking in again by a return air inlet, avoid excess environment temperature, and improve the refrigeration effect.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an outdoor unit of an air conditioner and a control method for preventing return air. Background technique [0002] Such as figure 1 As shown, the outdoor unit of the air conditioner is installed in the installation station of the building. The installation station generally has a gap structure formed by the side wall 104 and the rear wall 105 of the building. The casing 101 of the outdoor unit is located in the gap, and the air outlet 102 The air return port 103 is located at the front end of the housing 101 and is located at the front end of the housing 101 . [0003] The air conditioner outdoor unit located at the installation station in the prior art has a big defect, that is, the air outlet is also located in the installation station, and the wind blown from the air outlet when the axial flow fan is working is in a certain slope, and the installation The gap between the sid...
