The invention discloses an intelligent industrial electrical cabinet air conditioner. A housing comprises a compressor, a condenser, a throttling valve and an evaporator that are fixed by a fixing frame; the condenser and the evaporator are distributed in a left and right structure manner, are fixed vertically, and lean forward or backward; and two air supply channels in opposite air supply directions are formed through the fixing frame. The intelligent industrial electrical cabinet air conditioner can realize the effects of high reliability, flexibility and accuracy control, and has higher mean time between failures and lower energy consumption; the evaporator and the condenser are high in heat exchange efficiency; and a maintenance period of the normal refrigeration efficiency is longer.
Description
technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration device for outdoor electrical refrigeration. Background technique [0002] Industrial air conditioners are widely used in various industries. The more common industrial air conditioners are often matched with equipment cabinets to meet the application needs of the industry. The main principle is that the compressor sucks the low-temperature and low-pressure gas refrigerant from the evaporator, and then compresses it into high-temperature and high-pressure gas. The refrigerant is discharged to the condenser, and the high-temperature and high-pressure gas refrigerant entering the condenser is cooled by blowing air under the action of the fan, and gradually changes into a medium-temperature and high-pressure gas-liquid mixed refrigerant through the (expansion) throttle valve to throttle and depressurize the injection flow direction The evaporator performs heat absorption, ev...
