Hvac System Air Flow

How to improve hvac airflow in rooms furthest from the heating unit.

Hvac system air flow.

Your system can overheat when there s not enough airflow to the air conditioning unit. Even systems in mechanical rooms can be obstructed by other equipment or storage items. What this means is that a merv 16 air filter will catch more dirt dust particles allergens etc. Boiler provides hot water to heat the air.

This means that air will be sucked through the filter before entering the mechanical equipment. 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. 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.

Your first step to improve hvac airflow should be to clear the area around your condensing unit. 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. 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.

Different systems put the filter in different places but most commonly it is located in the air return duct. 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. 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.

A typical forced air hvac system is designed to a closed loop system. Not enough return air vents. The location of your heating unit affects the air distribution throughout the house. Turning vanes are installed inside of ductwork at changes of direction e g.

Air flow resistance in an hvac system is measured in inches of water column w c. Careful sizing and installation of the. It includes the fan to move the air and equipment to condition the air before it is delivered to the conditioned space. Plenums are the central distribution and collection units for an hvac system.

Than a merv 1 air filter. Central air handling system generally contained in a mechanical room. 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. The return plenum carries the air from several large return grilles vents.
