Problems solved by technology

However, the existing window-type air conditioner is an integrated air conditioner, and a motor drives the inner and outer wind wheels to exchange heat, so the inner and outer rotation speeds are the same.
When the system pressure is reduced by increasing the outdoor side air volume, since the inner and outer wind wheels are driven by the same motor, the indoor side air volume also increases, the heat transfer capacity of the indoor heat exchanger increases accordingly, and the return air temperature of the system rises. High, causing the system pressure to increase, causing the pressure on the high pressure side of the system to exceed the allowable pressure range of the compressor, resulting in compressor tripping, the system cannot work normally, and the compressor may be damaged, causing user complaints

Abstract

The invention provides an integrated air conditioner and a control method for high temperature refrigeration. The integrated air conditioner comprises an air conditioner main body and an air guide channel, wherein the air guide channel is arranged above an outlet of an indoor side air channel of the air conditioner main body, an air inlet of the air guide channel is matched with the outlet of the indoor side air channel, and an air outlet of the air guide channel faces the outside air inlet side of an indoor side heat exchanger of the air conditioner main body, so that airflow in the outlet of the indoor side air channel is guided to the indoor side heat exchanger when the integrated air conditioner is in the high temperature refrigeration mode. By means of the technical scheme of the integrated air conditioner and the control method for high temperature refrigeration, the pressure of a system is reduced during high temperature refrigeration of the integrated air conditioner, the pressure of the high pressure side of the system is controlled in the pressure range allowed by a compressor, the problems that the system cannot normally work and a compressor is damaged due to the fact that the compressor is shut down are solved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an integrated air conditioner and a high temperature refrigeration control method. Background technique [0002] At present, the internal design temperature of the traditional air-conditioning refrigeration greenhouse is 27°C, the outdoor design temperature is 35°C, the indoor use range is 17 to 32°C, and the outdoor use range is 0 to 50°C, ignoring the user's demand for high-temperature refrigeration. Affected by global warming, or in some high-temperature operating areas, air conditioners need to perform high-temperature cooling. When the air conditioner operates under high temperature and overload conditions, it generally increases the outdoor side air volume to make the outdoor heat exchanger more fully exchange heat and reduce the system pressure. However, the existing window-type air conditioner belongs to the integrated air conditioner, and a motor drives the inn...
