Single Air Duct Variable Volume Control Damper For Air Conditioner Terminal Unit VAV Box

The single air duct variable air volume for air conditioner terminal unit--VAV box

It can be used in low pressure and medium pressure single air duct air conditioning systems. It can be used in a variety of control modes, and can be used for constant air volume systems as well as variable air volume systems. The cabinet is made of double-layer galvanized steel. The two layers are made of 25mm thick fiberglass insulation with anti-corrosion insulation. It meets the standards of UL-181 (Underwriters Laboratories) and NFPA90A (National Fire Protection Association). . The double-coated galvanized sheet has a precise and well-sealed valve (the air leakage rate of the damper does not exceed 1% at 1000pa and inlet pressure). The structure has the characteristics of firmness, no void on the inner surface, easy cleaning, no bacteria growth, and the like, and is particularly suitable for air conditioning systems in hospitals and clean rooms. And the unit outlet wind is equipped with a hook to facilitate on-site installation. The control part can be selected according to customer requirements, selected, designated control parts, can be completed before the product leaves the factory or installed by the customer. The unit has a total of 11 sizes to provide air supply in the air volume range of 70-8900m3/h.

The variable air volume air conditioner is divided into two parts: mechanical and control. The mechanical part includes a single air duct variable air volume air tank and an optional hot water reheat coil, electric heater, static pressure box, muffler and the like. The control section includes an electronic thermostat or digital thermostat, a heat exchanger, a wind pressure measuring device, a hot water valve controller or an electrothermal controller, and a digital network for digital thermostat and actuator communication. Operator terminal, communication adapter, etc. These products can be arbitrarily selected according to design or construction requirements. The variable air volume air conditioner has advantages over other brands of variable air volume social security.

The electronic controller contains smart chips, high degree of automation, wind pressure measuring device, controller and driver concentrated in the variable air volume box. The structure is simple and long-lived. The electronic temperature controller has nighttime normal temperature control function and nighttime change. Set temperature function and constant air volume control function. All power consumption is less than 3 watts, and the energy saving effect is remarkable. It maintains the required air supply volume according to the electronic controller setting regardless of the variable air volume equipment inlet or system pressure, temperature and humidity. The digital controller can be managed and operated reliably with computer operation. Powerful, variable static pressure control, through digital networking, the operator can monitor the air conditioning effect of all variable air volume devices and air conditioning areas on the operating terminal, and can control the operation of the variable air volume air conditioning system at any time, through the digital interface, The control of a variable air volume air conditioning system can be called a part of the automatic control system and is an ideal way to achieve intelligentization.
