Air conditioner for operating under high temperature conditions

Abstract

The invention discloses an air conditioner for operating under high temperature condition, comprises an air conditioner cabinet body with upper and lower layers, An open refrigeration compressor is arranged on one side of the lower layer of the air conditioner cabinet body, the refrigerant outlet of the open refrigeration compressor is connected with the refrigerant inlet of the condenser arrangedon the lower side of the air conditioner cabinet through a pipeline, the refrigerant outlet of the condenser is connected with one end of the expansion valve through a pipeline, the other end of theexpansion valve is connected with the refrigerant inlet of the upper evaporator arranged in the air conditioner cabinet through a pipeline, The refrigerant outlet of the evaporator is connected with the refrigerant return port of the open refrigeration compressor through a pipeline, an embedded electric control box is arranged on one side of the upper evaporator of the air conditioner cabinet body, and the air outlet of the cold air is arranged on the top and / or bottom of the air conditioner cabinet body. The air conditioner has the characteristics of simple structure, convenient use, good refrigeration effect and long-term stable operation under 90-working condition in extremely harsh environment.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration equipment, in particular to an air conditioner for operating under high-temperature conditions. Background technique [0002] In the prior art, in the field of industrial refrigeration, especially in ultra-high temperature environments such as industrial electrical rooms and driving cabs in the metallurgical casting industry, industrial refrigeration and air conditioners are widely used. The more common industrial air conditioners on the market are: side-mounted Embedded industrial air conditioners, top-mounted industrial air conditioners, split-type industrial air conditioners, seat-mounted industrial air conditioners, etc., due to the limitations of current industry technology development, the refrigeration systems and compressors of these industrial air conditioners are usually fully enclosed. When the temperature is as high as 90°C, almost all industrial air conditio...

Problems solved by technology

[0002] In the prior art, in the field of industrial refrigeration, especially in ultra-high temperature environments such as industrial electrical rooms and driving cabs in the metallurgical casting industry, industrial refrigeration and air conditioners are widely used. The more common industrial air conditioners on the market are: side-mounted Embedded industrial air conditioners, top-mounted industrial air conditioners, split-type industrial air conditioners, seat-mounted industrial air conditioners, etc., due to the limitations of current industry technology development, the refrigeration systems and compressors of these industrial air conditioners are usually fully enclosed. When the temperature is as high as 90°C, almost all industrial air conditioners on the market cannot operate normally, which poses a great threat to the life safety of operators in the cab operating in the metallurgical high-temperature environment, and cannot continue to work at all, making production basically at a standstill
