Clean air-conditioning system consists of cold (heat) source, air handling equipment, ventilation systems, water systems and automatic control and regulation of five major components.
Cold source is for the air handling equipment to provide cold to cool the air supply air. Commonly used cold source is all kinds of chiller, they provide low-temperature water (for example, 7 ℃) to the heat transfer equipment to cool the air, but also useful for refrigeration system evaporator to directly cool the air; commonly used air conditioning heat source heat pump chiller, all kinds of boilers, electric heaters and so on.
Air-handling equipment is the role of the air supply air treatment to the required state. Commonly used air treatment equipment are air filters, air coolers, air heaters, air humidifiers, etc., the collection is installed in the air handling unit.
Wind system including air conditioning air supply system, back to the wind system and exhaust system. The role of the air supply system is to send the processed air to the corresponding function room, the basic components are fans, duct system, insulation system, indoor air supply and end of the high-efficiency filtration device. The role of the exhaust system is the air from the indoor exhaust, and exhaust air transported to the specified location, can be discharged to the outdoors, but also part of the exhaust air sent to the air treatment equipment and new air mixed as a supply of air, re-use of this part of the exhaust is called back to the air, back to the air is composed of a certain proportion of distribution.
The main function of the water system is the refrigerant water or heat medium water from the cold source or heat source to air handling equipment. The basic components of the air-conditioning water system is the water pump and water pipe system.
Bbecause the air conditioning system of the hot and cold load is variable, which requires the air conditioning system should also be adapted to change the working conditions.
