Combined air-conditioning box: mainly extracting indoor air (RETURN AIR) and partial new wind to control the air temperature and air volume and maintain indoor temperature.
A Hu-Air Handling Unit Air Processor (AHU); equipment for adjusting indoor air temperature and cleanliness. There is an air filter that meets the air heater, air cooler, air humidifier for hot wet treatment requirements, and the air filter for purifying the new wind, returning air, and the muffler for reducing the noise of the ventilator noise.
Pre-cooling air conditioning box: Primary Air Unit pretreats outdoor new wind and is sent to the fan disk tube (FCU).
Recycled AirHandling Unit Circulating Air Storate.
A new fan: It is an air conditioning apparatus for providing fresh air. Function The requirements of the use environment can reach constant temperature constant humidity or fresh air. The working principle is that the fresh air is removed from the outdoor, dehumidification (or humidified), cooling (or warming), etc., and replaces the original air in the chamber when it enters the indoor space. Of course, the functions mentioned above have to be determined according to the needs of the environment, the more complete compatibility is higher.
Dry cooling coil (referred to as a dry disk tube or dry coil): is used to eliminate thermal inside.
Direct Digital Control
The Chinese means that the HEPA standard filter is achieved, and the HEPA network is characterized by air, but the fine particles cannot be passed. It has a diameter of 0.3 micrometers (1/200 hair diameter of hair) to reach 99.7%, which is the most effective filtration of contaminants such as smoke, dust and bacteria. (Smoke produced smoke particle diameter is 0.5 microns) It is an internationally recognized high-efficiency filter material. It is widely used in high-clean and net venues such as operating room, animal laboratory, crystal experiment and air.
Wind turbine: Fan Control Unit fan coil is the end device of the air conditioning system, its working principle is the air in the unit constant recirculation in the unit, so that the air is cooled (heated) through cold water (hot water) coil (heated) Keep the room temperature constant. Mainly relied on the mandatory effect of the fan, so that the air is heated by the heater surface, thus strengthening the convection heat exchanger between the heat sink and the air, can quickly heat the air in the room.
Vehicle Air Conditioning System (VAV) Control Principle: The Wind Controller and Room Temperature Control Let the indoor cascade control, the indoor temperature is mainly controlled, and the air flow is an auxiliary control amount. The wind content controller detected the actual temperature detected by the room temperature sensor, with the set temperature, to output the adjustment signal of the desired air volume, adjust the wind valve at the end of the wind, change the air volume, so that the indoor temperature is maintained Predetermined area. At the same time, the wind turbine pressure sensor detects the pressure change in the air, adopted PI or PID adjustment, and controls the speed of the wind turbine, eliminates the effect of pressure fluctuation through the inverter.
Chinese means \"low humidity air conditioning unit \". The low-humid air conditioning unit is an efficient and fast air dehumidification equipment, which is mainly composed of dehumidifier group, regeneration heating system, processing fan, regenerative fan, front, rear test, electric control cabinet, and casing combination into a box structure. Units. The casing material is used in double-layer painted color mold, which is filled with a polyurethamide foam insulation material in the compartment, which can effectively prevent temperature and humidity interference of external air.
Fan filter units, meaning in Chinese means \"fan filter unit (crew) \". That is, the fan and filter (high efficiency filter (HEPA) or ultra-efficient filter (ULPA) are combined to form a terminal purification device that provides power. Specifically, it is a self-driving force, a modular end air supply device having filtering efficacy. The fan was filtered from the top of the FFU and filtered through HEPA, and filtered clean air was evenly sent from 0.45 m / s ± 20% wind speed.
