The main components:
The HVAC is mainly composed of compressors, condenser, evaporator, and throttling mechanism.
The compressor can be divided into a piston and rotating type according to the compression method; the effect of the condenser is to cool the refrigerant with high temperature and high pressure into a liquid or gas liquid mixture;It is an important part of the pressure difference between the condenser and the evaporator.
System composition:
The HVAC also includes refrigeration units, cooling water systems, media water and water systems, heating systems, etc.
The refrigeration unit consists of a compressor, condenser, evaporator, etc.; the cooling water system includes cooling towers, cooling water pumps, etc.; Media water and water systems include media water pumps, water signs, water collectors, etc., Having heat exchanges pumps, etc.
Features:
HVAC crew not only has cooling and heating functions, but also air treatment, such as filtering, humidification, etc., creating a more comfortable indoor environment.
Safety Facilities:
The HVAC is usually equipped with safety facilities such as safety valves, high and low pressure controllers to ensure the safe operation of the equipment.
The above is the introduction of the device of the HVAC unit
