The type and function of the Fan Hood are generally used in the vent actuator actuator system. Air Duct. In a ventilation system, air goes in and out through the exhaust pipe. The Cross sections of the ventilation ducts are circular and rectangular. In addition to straight pipe, according to the actual needs of the project, the ventilation pipe by the elbow, front and rear elbow, elbow diameter, tee, four-way pipe composition. The utility pipe of ventilation and air conditioning engineering is mainly composed of common steel plate, galvanized steel plate, stainless steel plate, aluminum plate and other metal pipes, polyvinyl chloride plastic plate, plastic composite plate (the surface of common steel plate is sprayed with 0.2-0.4 mm plastic layer) and glass steel pipe, etc. . Frp Duct is divided into insulation and non-insulation two categories. Glass Fiber Reinforced Plastic (GFRP) non-insulated pipeline is called glass fiber reinforced plastic (GFRP) pipeline, insulation layer (namely Honeycomb Sandwich Board or Sandwich Board) glass fiber reinforced plastic pipeline is called Sandwich Structure Pipeline. Brick, concrete, drywall. 2. All kinds of vents. The ventilation pipe is provided with various air supply or exhaust modes to regulate the amount of indoor air in and out, so that indoor air can be in and out. There are many types of Tuyere, commonly used tuyere type is rectangular Tuyere, with Grille and Bar Grille, with rod adjustment device, other types of non-rod adjustment device. Tuyere is divided into single-layer, double-layer, three-layer and diffuser. 3. Valve. A ventilation assembly installed in a ventilation duct to regulate air flow and to close a single branch. Common Valves used in ventilation and air conditioning projects are plug valves, Butterfly Valves, multi-leaf control valves, Circular Open Valves, Air Treatment Room by-pass valves, fire valves, check valves and so on. The utility model is mainly used for connecting the air duct and the equipment. The utility model has the main function of isolating the expansion and preventing the indoor noise caused by the vibration of the air passage. The total length of the flexible short pipe is 150-250 mm.5. Local Hood. The main function is to remove the residual heat in the equipment. The most common parts of the hat are the canopy, the side hood, and the hat. 6. Waterboarding. The baffle is one of the components of the spray chamber and is divided into a front baffle and a rear baffle. The function of the front baffle is not only to keep out the water droplets that may splash during the spraying process, but also to make the air entering the spray chamber flow uniformly throughout the whole area, so it is also called the wind plate or the wind guide plate or the water-wind separator. After the dehydration of water, generally made of galvanized steel or glass plate. Kill. Air Filter. Is a kind of indoor air into the dust removal purification equipment, can be divided into initial effect (pre-filtering) , medium effect, high efficiency filtering. 8. Silencer. A device that prevents noise from entering a room. In the air conditioning engineering, anti-noise, resonance Muffler and Broadband Composite Muffler are used. 9. Dust Collector. The utility model relates to an air purification device, which is generally divided into a cyclone dust catcher, a wet dust catcher, a bag dust catcher, etc. . 10. Ventilators. A machine in a mechanical ventilation system that forces air to move. Fans are the main equipment for ventilation and air conditioning. According to the structure principle, it can be divided into axial fan and Centrifugal Fan. Kill. Air Conditioning and refrigeration. The installation form of Centurystar refrigeration system is as follows: 1 unit installation form, namely refrigeration compressor, condenser, evaporator and all kinds of auxiliary equipment are connected with refrigeration pipeline to form refrigeration system, central Support Refrigeration System: Chiller, condenser, evaporator and all kinds of auxiliary equipment are assembled by manufacturers into a whole installation form.12. Bathroom. The utility model relates to a multifunctional air-conditioning device, which can be made of steel plate or concrete, and has a nozzle, a water supply pipe to the nozzle, accessories, etc. . 13. Shutters. The utility model is used for blocking the entrance of outdoor sundries, shelter from rain, decoration, etc. . 14. Heater. Is to ensure that the air into the room with a certain temperature and relative humidity of the equipment, divided into a heater and a second heater. Heaters used in front of a shower or surface cooler are called primary heaters and are used to raise the temperature of the air and absorb moisture. Heaters used behind showers or surface coolers are called secondary heaters. It heats the air behind the shower to the desired temperature and relative humidity. 15. Hat. It’s used at the end of the exhaust system to get dirty air out of the room. According to its form: for the General Mechanical Ventilation System Umbrella Cap, for the dust removal system cone cap, for the natural ventilation system simple cap.
