Air conditioning system how to classify, for what occasion
In accordance with the purpose of the use, the air conditioning can be divided into:
Comfort air conditioning---request temperature suitable, comfortable on the adjustment precision humidity no strict requirement, for housing, offices, theaters, shopping malls, stadiums, automobiles, ships, aircraft, etc. Process air conditioning---on the temperature of the precision requirements, regulating air cleanliness should also have higher requirements. For electronics production workshop, precision instrument manufacturing workshops, computer room, biological laboratories, etc. In accordance with the air treatment methods can be divided into:
Centralized air conditioning (Central)-air treatment equipment is concentrated in the central air conditioning room, the processed air through the duct to the air conditioning system in each room. Applicable to the area, the room set, each room heat and moisture load very close to the selection of sites, such as hotel, Office building, ship, factory, etc. System maintenance conveniently, the device easier to resolve noise and vibration isolation. -Centralized air-conditioning---both the central air conditioning and air terminal unit of air conditioning systems. This system is more complex, you can achieve a higher adjustment precision. Applicable to air precision high demands on the workshops and laboratories. Partial air conditioning – each room has its own air conditioning device handling. Air conditioner can be directly installed in the room or in the adjacent room, in-place processing of air. Suitable for small size, room dispersion, heat and moisture load difference of big occasions, such as Office, room, family, etc. The device can be a single-standing air conditioning phase groups, such as window type, split air conditioner, etc. You can also set by pipeline to the hot and cold water of fan coil-type air conditioner system, composed of various rooms by the need to adjust the room temperature. The cooling capacity can be divided into:
Large air-conditioning units such as horizontal Assembly table shower, air conditioning units, apply to the big shops, cinemas, etc.
Medium-sized air conditioning units-such as chillers and conditioner, etc., in small workshops, computer room, Conference Hall, restaurant, etc.
Small air handling units-such as window type, split air conditioner, for Office, home, hotel, etc. How many of the new amount of wind to points:
DC system---air-conditioner with air for fresh air, sent to the room into heat and moisture Exchange after release into the outdoors, there is no return air pipe. This kind of system health conditions, energy consumption, efficiency, and to have a harmful gases produced by the workshop. Laboratory, etc. Closed system-air conditioning system with air all recycling, not additional fresh air system. Systems, small power consumption, and poor sanitary conditions, need for oxygen in the air with carbon dioxide regeneration and suction device. As for the underground construction and submarines of air conditioning, etc. Hybrid system---air-conditioner handling of air from the air and mixture of fresh air. It also has the DC and the advantages of closed type, apply generally, such as hotels, theatres and other places of the air conditioning system. The air velocity: high-speed system---main duct of the wind speed 20-30m/s. Low-speed system---main duct velocity 12m/s below.
