High Pressure Roof Top Air Handling Unit

A package rooftop air handling unit ahu from an actual project will illustrate how mixed air plenum pressure control can be implemented.

High pressure roof top air handling unit.

These are usually mounted on roof curbs but can be also mounted on structural supports or on grade. You can watch the video on this article by scrolling to the bottom. Add these two pressures together to find the equipment measured total external static pressure. These are particularly popular for single story commercial buildings warehouses and big stores.

The roof top units rtu are other common air handlers designed for outdoor use. Operation up to 150 pa esp thermally and acoustically insulated unit case ideal comfort and indoor air quality for all seasons. All evaporator coils are tested against leakage by air pressure under water dust storms and the general level of available maintenance in tropical countries ensures this condenser coil design shall provide long life and maintenance free operation with the least possibility operational blockage on the condenser ample condenser surface and sensible air flow across the condenser ensures a low. Air handlers usually connect to a ductwork ventilation system that.

We ll look at different examples of typical ahu s along with animations for components such as dampers heating and cooling coils heat wheels humidifiers run around coils heat exchangers and more to help you learn hvac engineering. The pressure exiting the equipment is a discharge or positive pressure. If you re looking for high quality refrigeration components and solutions then i recommend checking out what danfoss has to offer. Wg of total static pressure.

In this article we ll be learning how air handling units or ahu s work. Roof top package air conditioners. Package hygienic air handling units. A 10 ton packaged unit in a rooftop application placed on a curb.

A draw through airfoil supply fan providing 20 000 cfm at 5 32 in. An air handler or air handling unit often abbreviated to ahu is a device used to regulate and circulate air as part of a heating ventilating and air conditioning system. Chillers air handling units and rooftop units are used extensively within hvac systems for commercial properties. The unit s characteristics include.

Where the ventilation outside air load is very high. An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. Based on a typical vav air handling unit configuration oa ra mixing box high efficiency filter hot water heating coil chilled water cooling coil and draw thru supply fan wi th a single discharge opening off fan section operating at 13 000 cfm and 2 in. The pressure entering the equipment is a suction or negative pressure.
