Window-type air conditioner and control method thereof

Abstract

The invention provides a window-type air conditioner and a control method thereof. The window-type air conditioner comprises an air conditioner main body, a by-pass air flue and an air guiding device; and an air inlet of the by-pass air flue communicates with an indoor side air flue outlet of the air conditioner main body, an air outlet of the by-pass air flue faces the upper portion of a compressor of the air conditioner main body, and the air guiding device is installed in the by-pass air flue for controlling the air volume flowing through the by-pass air flue. According to the technical scheme, when a product operates at the high-temperature refrigerating working condition, cold air flowing through the indoor side air flue outlet is guided into the upper portion of the compressor of the air conditioner through the by-pass air flue so as to lower the temperature of the high-pressure side of the compressor, so that the pressure of a whole refrigerant loop system is lowered to a certain extent, the problems such as tripping or damaging and the like of the compressor are avoided, and operating reliability of the product is improved; and the bearing ability of the product for the outdoor environment temperature is improved to a certain degree, so that the applicable occasions of the product are broadened.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a window type air conditioner and a control method for the window type air conditioner. Background technique [0002] In the existing window-type air conditioners, in order to avoid problems such as compressor tripping caused by the increase in the internal system pressure of the product, the upper limit of the outdoor operating temperature is generally limited to below 50°C. However, with the global With the further strengthening of the warming trend, the highest temperature in some areas has reached 50°C or even higher, which makes this type of window-type air conditioner more and more unable to meet the needs of users in high-temperature refrigeration. Therefore, it is urgent to design A window air conditioner capable of performing cooling operation in an environment with a temperature higher than 50°C and avoiding the problem of compressor tripping.
