Hvac System Air Flow

A high efficiency air filter introduces more air resistance that a low efficiency air filter.

Hvac system air flow.

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

How to improve hvac airflow in rooms furthest from the heating unit. Even systems in mechanical rooms can be obstructed by other equipment or storage items. A typical forced air hvac system is designed to a closed loop system. 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.

Your system can overheat when there s not enough airflow to the air conditioning unit. The hvac system an hvac system has different components. 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.

Plenums are the central distribution and collection units for an hvac system. Your first step to improve hvac airflow should be to clear the area around your condensing unit. Blocked vents and registers one bit of advice we can offer for how to. The vanes guide the air so it can follow the change of direction more easily.

Turning vanes are installed inside of ductwork at changes of direction e g. The location of your heating unit affects the air distribution throughout the house. Central air handling system generally contained in a mechanical room. Boiler provides hot water to heat the air.

Determine the direction of the air flow. 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. Air flow resistance in an hvac system is measured in inches of water column w c. At 90 turns in order to minimize turbulence and resistance to the air flow.

This means that air will be sucked through the filter before entering the mechanical equipment. Than a merv 1 air filter. It includes the fan to move the air and equipment to condition the air before it is delivered to the conditioned space. Not enough return air vents.
