Working principle of welded air duct fan coil unit

The body structure of the air disc is compact and durable. The welded air duct of the fabric air duct is generally made of high-quality galvanized steel sheet. The whole is connected to the water pan. The installation of drainage pipes and routes is simple, and the upper and lower docking and air supply methods can be changed anytime and anywhere to match the situation on the spot. The generator set can be installed in all indoor spaces. The general expansion tube processing process of the air disc improves the inseparable contact between the copper tube of the heat exchanger and the air conditioner and the aluminum and platinum, and has good heat conduction characteristics; the effective overall design of the centrifugal fan and the cyclone, and the high-quality sound insulation and heat insulation materials make the generator set. The noise is lower than the national industry standard 1-3dB(A); the energy consumption of the wind disk is low: the centrifugal fan is effectively paired with the heat exchanger, and the three-speed adjustable exhaust air volume makes the centrifugal fan less power consumption. The air disk mainly uses the mandatory effect of the centrifugal fan to make the gas heated according to the surface layer of the electric heater, thus strengthening the convection heat transfer effect between the heat pipe radiator and the gas, and the carbon steel welded air pipe can quickly heat the gas in the room . The wind disk is the end equipment of the air conditioning unit. Its principle is that the gas in the room to which it belongs is continuously circulated in the generator set, so that the gas is cooled (heated) according to the cold water (boiled water) fan coil to maintain the stability of the room temperature. Generally, the fresh air system is sent into the room according to the solution of the fresh air unit, so as to consider the need for the exhaust air volume of the central air-conditioning room. Because this type of heating method is only based on convection heat exchange, the room cannot reach a better comfortable level, so it is only suitable for places with short waiting time, such as: company offices and hotels, hospital clinics, restaurants , processing plants, hospital clinics, exhibition halls, large shopping malls and office buildings and other multi-room or large-capacity industrial production and central air-conditioning places for industrial buildings. Because the centrifugal fan is upgraded, the project cost and operation cost are increased, and the maintenance and management methods of the machinery and equipment are also complicated.
