Hvac System Air Flow

The hvac system an hvac system has different components.

Hvac system air flow.

Plenums are the central distribution and collection units for an hvac system. Determine the direction of the air flow. The return plenum carries the air from several large return grilles vents. Different systems put the filter in different places but most commonly it is located in the air return duct.

Even systems in mechanical rooms can be obstructed by other equipment or storage items. Inadequate return air seriously limits both air flow rates and also the degree to which building air is cooled or heated by the hvac system. In a perfect world it produces a certain amount of air and that air is distributed throughout the home so the same amount of air is returned from the home conditioned and then redistributed. A typical forced air hvac system is designed to a closed loop system.

Blocked vents and registers one bit of advice we can offer for how to. How to improve hvac airflow in rooms furthest from the heating unit. Central air handling system generally contained in a mechanical room. This means that air will be sucked through the filter before entering the mechanical equipment.

Air flow resistance in an hvac system is measured in inches of water column w c. Combination hvac solutions created with iflow hydronic furnaces can deliver the highest efficiencies of any heating equipment in the north american industry. The vanes guide the air so it can follow the change of direction more easily. You might think that a merv 16 air filter is the one to get without question but if your hvac system isn t capable of handling such an air filter you re in for some trouble.

It includes the fan to move the air and equipment to condition the air before it is delivered to the conditioned space. Residential units normally have about 0 5 inches of added pressure in the system and the typical unit is allocated only about 0 03 inches w c. A high efficiency air filter introduces more air resistance that a low efficiency air filter. Your first step to improve hvac airflow should be to clear the area around your condensing unit.

Iflow holds the highest result of any combination system in north america tested to the csa p 9 11 combination system efficiency performance standard and holds 4 of the 6 top efficiency. The photograph above shows a return air inlet grille for a commercial office space after the air conditioning return register and ducts were increased in size as part of improvements in the building. Not enough return air vents. Boiler provides hot water to heat the air.
