Refrigeration people need to know the classification of air conditioning
1. According to the purpose of use, which types of air conditioning can be divided into?
Comfortable air conditioning: the temperature is appropriate, the environment is comfortable, the precision of temperature and humidity regulation is not strict requirements, used in housing, office, theater, shopping malls, stadiums, cars, ships, aircraft, etc.
Process air conditioning: there are certain requirements for temperature adjustment precision, in addition, the cleanliness of the air should also have high requirements. Used in electronic device production workshop, precision instrument production workshop, computer room, biological laboratory, etc.
2, according to the way of air treatment, which can be divided into several categories?
Centralized air conditioning: Air handling equipment is concentrated in the central air conditioning room, and the treated air is sent to the air conditioning system of each room through the air duct. Suitable for large area, room concentration, each room heat and humidity load is close to the place selection.
Semi-centralized air conditioning: An air conditioning system with both central air conditioning and terminal units for handling air. This kind of system is more complex and can achieve higher adjustment precision. It is suitable for workshop and laboratory with high requirement of air precision.
Local air conditioner: An air conditioner in which each room has its own equipment for handling air, such as a split air conditioner. It can also be a fan coil type air conditioner system composed of pipes for hot and cold water, and each room adjusts the temperature of the room as required.
3, according to the cooling capacity which can be divided into several categories?
Large air conditioning units: such as horizontal assembly shower type, surface cooling air conditioning units, used in large workshops, cinemas, etc.
Medium air conditioning units: such as chiller and cabinet air conditioner, etc., used in small workshops, computer rooms, meeting rooms, restaurants and so on.
Small air conditioning unit: split air conditioner for office, home, guest house, etc.
4. According to the amount of new air, which categories can air conditioning be divided into?
Direct flow system: The air treated is fresh air, which is sent to each room for heat and humidity exchange and placed outdoors without return air pipe.
Closed system: The air treated by the air conditioning system is all recirculated, and no fresh air is added.
Mixed system: The air treated by air conditioner is mixed by return air and fresh air.
5. Classified by air supply speed?
High-speed system: Wind speed of main duct 20-30m/s.
Low-speed system: the wind speed in the main duct is less than 12m/s.
Industrial air conditioning, chemical fiber industrial air conditioning, chemical fiber industry refrigeration, textile industrial air conditioning, dust-free workshop cooling, ventilation pipeline, cooling tower, freezer and other air conditioning units and accessories.
