Air handling unit design

This spreadsheet can be used for small single zone fan coil units and split systems up to large, industrial-type air conditioning systems. Casing is the body of the air handling unit. Provide more insulation for outdoor unit. For outdoor units slope the roof to prevent rain water.

An air handling unit often abbreviated as AHU is a very important component of central-air-conditioning system , that is responsible for drawing return air from the indoor spaces, mixing it with outdoor air and processing that air to the appropriate conditions to be supplied to the building spaces.

There are basically two types of air handling unit that are in used and they are the Draw-Through or Blow-Through. Air Handling Unit Design for High Performance Buildings J. In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network. The design can be vertical or horizontal. The air handling units selection software by ALTEC srl is complete in functions, easy to use and suitable for any manufacturer.

It consists of a base module and different additional modules, suitable to cover the many requirements that an air handling units manufacturer must cope along the entire process of selection, design and construction of the units. Follow these design and troubleshooting tips when specifying air handling units (AHUs).

When beginning a project, spend the time to list all the various goals and constraints including proposal requirements, applicable codes and standards, energy goals, and owner preferences. Our range of experience air handling unit engineers will work in partnership with you to ensure that we design a unit to meet and exceed your exact specification. Each AHU arrangement and component selection is individually designed to your specific requirement ensuring the air handling unit produced performs with peak performance and optimised efficiency.

A larger air handler that conditions 1 outside air , and no recirculated air , is known as a makeup air unit (MAU) or fresh air handling unit (FAHU). An air handler designed for outdoor use, typically on roofs, is known as a packaged unit ( PU ) or rooftop unit ( RTU ). Building air handling systems that meet today’s complex energy and performance demands may seem like hard work. But Air Enterprises makes air handling unit design look easy, from the preliminary planning and goal-setting process, through design options and drawings to meeting our clients’ detailed specifications and budgets. As a custom provider of air handling equipment we take pride in our ability to find efficient solutions to unique requirements prevalent in today’s market place. Altec srl can relies on almost three decades long experience of providing premium quality solutions (products plus services) tailored to engineer solutions for every problem in air treatment mechanical industry.

The system makes it possible to customize an installation in terms of airflows and the functional sections include as well as its controls. HVAC SysteZoning Design Considerations- Part-3. Soundproofing of Air Conditioning Ducts. Safety Devices in Air Conditioning and Refrigeration Plants. The air is filtered by pleated paper filters called high efficiency particulate air (HEPA) filters which, depending upon the classification of the rooms, are located either within the air handling unit or where the air enters each room.

These units are connected to a high-pressure duct network that delivers air through an inefficient VAV box with a fixed geometry diffuser.

The custom air handling unit , or the AHU for short, is a very important part of your office or home because it pretty much controls all the air flow in the building. It circulates the air that comes from the air conditioning system, the heating system, and the overall ventilation system. Air handling systems range in complexity from stand-alone units that serve individual rooms tolarge.

When a supply air system is required to operate on 1 outside air during smoke mode operation, the system shall be designed with sufficient heating capacity to maintain a minimum of degrees at the air handling unit discharge under the 99. When designing a natatorium the relative humidity, air temperature, pool water temperature, pool activity levels, air distribution, outdoor air , exhaust air and pool water treatment are all key aspects that must be addressed to provide a good environment.
