Air Conditioning System Category.
1. The air-conditioning system is classified according to the setting of air handling equipment.
Centralized system: air handling equipmentConcentrated in the machine room。The treated air is fed into the air-conditioned area by the air duct, egCombinedAir conditioning systemv**Variable air volumeAir conditioning systemConstant temperature and humidityAir conditioning system
Semi-centralized system: In addition to having centralized air handling equipment, in:in each air-conditioned roomIt is also set separately to process airEnd device, for exampleFan coil unit and fresh air system, multi-line and fresh air system, inducer systemWait.
Fully decentralised systems: each is undertaken by its own integral or split air conditioner, e.gUnit air conditioner, multi-connection systemWait.
2. The air-conditioning system is classified according to the electronic classification used to bear the indoor air-conditioning load.
All airSystem: Indoor air conditioning loadIt's all borne by the air, there was a replay and.
Primary and secondary return air system, etc. , for examplev**Variable air volume air conditioning system
airwaterSystem: This type of air conditioning load is made up of treatmentair and waterShared burdens, egNewWind plus fan coil unit system
FullwaterSystem: Indoor air conditioning loadIt's all about water, such as:Fan coil unit system without fresh air supplyThis kind of system cannot solve the problem of ventilation in air-conditioned rooms, and is usually not used alone;
RefrigerantsSystem: The evaporator is indoors, which directly absorbs waste heat and humidity, for exampleUnit air conditioningdevice, multi-online systemWait.
According to the working pressure of the air duct system, it is classified as micro pressure, low pressure, medium pressure and high pressure. Positive pressure: 125,435;Negative pressure: 125,424.
