  • Use of direct and indirect evaporative cooling
  • Large air volumes
  • Minimized footprint
  • Redundancy at the component of unit level
  • Some strategies incorporate heat recovery
  • Some strategies incorporate outside air and other strategies eliminate outside air
  • Focus on low energy use
  • High efficiency fans
  • Internal spring isolation of fans for minimized vibration transmission

Hospitals

Hospital air handling equipment is designed for cleanliness of the airstream. Many areas in a hospital are required by code to have high efficiency filters in the position furthest downstream in the air handling unit.

Redundancy is a requirement in many health care applications and redundancy of components and units can be incorporated into the air handling units

Hospitals are designed for a long life and operate continuously so the air handling equipment has to be designed for long life and maintainability.

Some typical features of hospital air handling unit include:

  • Final filters
  • Heavy duty casings
  • Low leakage casings
  • UV lights
  • Individually supported and removable coils
  • Stainless steel drain pans and cooling coil racks
  • Integral motor lifting beams
  • Welded aluminum or steel fan wheels
  • Ieee841 industrial grade motors
  • Aluminum dampers with hexagonal slip free linkage
  • Large access doors with metal handles, inspection windows, automotive grade bulb seals
  • Wash-down liners
  • Non-ferrous liners in cooling and humidification sections.
  • Doors opening against unit operating pressure for air seal
  • Test ports
  • Internal spring isolation of fans for low vibration transmission

Because of continuous use, energy efficiency in hospital air handling units is critical.

The following can be utilized for lowest energy use:

  • High efficiency fans selected at an optimal operating point
  • Low pressure drop coils and filters
  • Energy recovery (Heat wheels, heat pipes, plate heat exchangers, run-around loops)
  • Integral unit mounted silencers with low air pressure drop

Safety is most acute in facilities that may have occupants that are not mobile. As such, some jurisdictions have fire codes which restrict the use of materials such as foam insulation in hospitals because of their high flame-spread and smoke-developed ratings. Haakon provides insulating materials which have low flame-spread and smoke-developed ratings.

Industrial

Industrial job sites require rugged equipment to withstand the harshest conditions.

Typical features for industrial air handling units are:

  • Stainless steel liners

Institutional

Institutional buildings are designed for a long life and the air handling equipment must also be designed for a long and trouble-free life. Low energy use is important for these facilities.

Lab Exhaust

Because materials used in laboratory experiments or processes are variable, the exact properties of what is passing through the exhaust airstream are often unknown. The air handling equipment must be designed for a wide range of potential contaminants.

Some typical features in lab exhaust air handling units are:

  • Heat recovery totally isolated from supply airstream
  • Stainless steel internal casing liners
  • Double wall low leakage casings
  • Stainless steel or anodized aluminum dampers

Office Buildings

Office buildings are developed to provide quiet working space for occupants. Often in towers units are placed in mechanical rooms on each floor. Because of the proximity to the occupied space, quiet operation is the primary consideration in designing the air handling equipment. In addition to the floor by floor compartment units, there is often a central make up air unit serving the building which provides ventilation air and incorporates heat recovery.

Typical features in an office air handling unit may include:

  • Thick sound absorbing walls with perforated liners
