Hvac System Air Flow

Combination hvac solutions created with iflow hydronic furnaces can deliver the highest efficiencies of any heating equipment in the north american industry.

Hvac system air flow.

Even systems in mechanical rooms can be obstructed by other equipment or storage items. 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. Than a merv 1 air filter. Not enough return air vents.

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. The location of your heating unit affects the air distribution throughout the house. How to improve hvac airflow in rooms furthest from the heating 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 hvac system an hvac system has different components. Your system can overheat when there s not enough airflow to the air conditioning unit. 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.

Air flow resistance in an hvac system is measured in inches of water column w c. What this means is that a merv 16 air filter will catch more dirt dust particles allergens etc. 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. It includes the fan to move the air and equipment to condition the air before it is delivered to the conditioned space.

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. Your first step to improve hvac airflow should be to clear the area around your condensing unit. Turning vanes are installed inside of ductwork at changes of direction e g. A typical forced air hvac system is designed to a closed loop system.

Careful sizing and installation of the. Boiler provides hot water to heat the air. The vanes guide the air so it can follow the change of direction more easily. At 90 turns in order to minimize turbulence and resistance to the air flow.

A high efficiency air filter introduces more air resistance that a low efficiency air filter. 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. Determine the direction of the air flow. Plenums are the central distribution and collection units for an hvac system.
