Environmental -friendly hot and cold water air -conditioning units are a common air -conditioning equipment. It uses refrigerant cycles to make hot and cold water, and uses hot and cold water circulation to achieve the purpose of adjusting the indoor temperature.This air conditioner is usually composed of a refrigerant circulation system, water circulation system, and electrical control system.
In the refrigerant circulation system, the cooling agent absorbs the indoor heat, transmits to the outdoor through the refrigerant circulation pipeline, and then distributes the heat to the outdoor air through the radiator.During heating, the refrigerant absorbs the calories of outdoor air through the heat exchanger, and then passes the heat to the indoor through the refrigerant circulating pipeline, thereby adjusting the indoor temperature.
The principle of environmentally friendly hot and cold water air -conditioning crew is mainly through compression mechanism refrigerant to compress the refrigerant vapor into high -temperature and high -pressure overheated steam, and then enter the condenser to condense.In the condenser, the high -temperature and high pressure refrigerant steam exchanges heat with room temperature water, making the refrigerant vapor cooling into a high -pressure liquid, and at the same time, temperature water is also heated.The high -pressure liquid enters the evaporator through the expansion valve. Due to the decreased pressure, the liquid quickly vaporizes in the evaporator. After absorbing the heat of the cooling object, it becomes a low -pressure vapor. The compressor is once again inhaled and compressed.Outdoor, achieve the effect of refrigeration.
