Problems solved by technology
Since the critical temperature of carbon dioxide is only 31.1°C, which is far lower than the critical temperature of widely used refrigerants such as R22, R407C, R410A, R134a, etc., if air cooling is also used, the high-pressure side pressure of the carbon dioxide refrigeration system will be much higher , this aspect will lead to system security concerns, but also affect the efficiency of the system

Water cooling separate type carbon dioxide room air conditioner is of the refrigeration and air conditioning technical field. Its compressor outlet is connected to condenser cooling medium inlet, whose outlet is connected to throttle valve inlet, whose outlet is connected to evaporator inlet, whose outlet is connected to compressor inlet. The bottom of water collector is connected to water pump inlet, whose outlet is connected to condenser water current inlet, whose outlet is connected to sprinkling machine inlet, outer room machine blower fan is fitted on lateral surface of evaporation cushion and the inner room machine blower fan is installed on the lateral surface of evaporator, compressor, condensor, sprinkling machine, evaporation cushion, water collector, water pump, outer room machine blower fan are included in the shell of outer room machine, throttle valve, evaporator, inner room machine blower fan are included in the shell of outer room machine The invention uses water cooling to decrease the pressure of cooling medium high pressure side, does good to environment protection; does not include the single cooling tower necessary for water cooling aggregate and making the whole structure more compact.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a water-cooled split carbon dioxide room air conditioner using carbon dioxide as a refrigerant and water as a cooling medium, belonging to the technical field of refrigeration and air conditioning. Background technique [0002] Room air conditioners are widely used, and the annual output in my country reaches tens of millions. Compared with window air conditioners, split room air conditioners are generally popular because the compressor of the split room air conditioner is outdoors and the noise of the indoor unit is lower. Most of the room air conditioners currently on the market are split type, using air cooling, and using R22, R407C, or R410A as the refrigerant. Refrigerants R22, R407C, and R410A are all synthetic substances. Due to the inevitable discharge of refrigerants, any large-scale production and use of synthetic refrigerants will have adverse effects on the environment. Therefo...
