Definition of constant humidity air conditioning
Constant humidity air-conditioning, refers to the temperature, humidity and cleanliness have strict requirements of the special air conditioner, but also has energy-efficient, low noise and environmental protection functions, can be widely used in electronics (data center), optical equipment, cosmetics, medical and health care (hospitals, operating rooms), biopharmaceutical, food manufacturing and other industries.
Constant humidity air conditioning classification
According to the refrigeration mode is divided into: air-cooled type of frozen water type;
According to the way of sending wind is divided into: the upper send side back, the upper send bottom back and the lower send wind type;
According to the control accuracy is divided into: ordinary constant temperature and humidity air conditioning and high precision constant temperature and humidity air conditioning.
The automatic control of the air conditioning system
This design is an independent air conditioning system, the unit control procedure sits on the air supply temperature control, each air-conditioning system air supply general pipe is set up a total electric heater, each system room branch pipe set the end fine-tuning electric heater, according to the room temperature requirements, respectively, the choice of the instrument no-level control.
In order to save investment, humidity according to the system control, each air-conditioning unit at the return air vent set up a humidity sensor, control the humidity of the entire system.
In order to ensure the safety of the system, each air conditioning system air supply pipe is equipped with pressure differential controller, no wind pressure difference, electric heater can not be started.
Constant humidity air conditioning installation and commissioning
1、Installation of air conditioning systems
2、The installation of indoor and outdoor machines of the constant temperature and humidity unit, the base of the unit is to be flat, and the horizontal allowable deviation is 0.2\/100
3、Air-conditioning duct production and installation, wind pipe insulation, should be in accordance with the design drawings and the country's relevant construction acceptance norms construction.
4、Installation of the refrigerant pipe of the indoor and outdoor machines of the unit: the horizontal pipe section of the compressor exhaust pipe shall be not less than 1\/100 slope to condenser, u-bend is strictly prohibited. Pipe welding, test pressure, test leakage, sewage, test vacuum, insulation, filling refrigerant, should be strictly in accordance with the construction specifications and machine specifications.
5、Air-conditioning ducts using 30mm thick aluminum foil ultra-fine glass cotton board insulation, with insulation, good fire protection effect advantages.
6、Commissioning of air conditioning systems
Air conditioning system air volume adjustment, air volume adjustment according to the system, from the end of the system to start with the mainbranch pipe, adjust each branch of the pipe on the open multi-leaf adjustment valve, so that the air volume of each room to meet the design requirements, adjust the room back to the air blade angle, so that the room's air flow organization is uniform.
