The Amazing Advantages Of Bypass Dampers
When a small or single-zone makes a heat or cool call, bypass dampers are employed in zoning applications to relieve excessive system pressure. It allows surplus pressure to be deflected back into the air system and circulated. When some zone dampers are closed, you must channel the extra air to reduce excessive static pressure. It’s the equivalent of putting a hole in a straw and blowing through it to relieve lungs stress. We don’t just drill a hole in your ducting and call it a day; we replace it with another duct. A bypass duct is what it’s called. There’s a bypass damper inside. Your supply plenum is connected to your return ductwork by the bypass duct. Depending on the situation, the damper within permits or prevents air from entering the bypass duct. Assume you have a two-story house with two zones, one for each level. All of the zone dampers are open when the system is cooling two levels, allowing air to move freely. The bypass damper, on the other hand, remains closed. Assume you simply need air conditioning upstairs. The downstairs dampers will close, while the upper dampers will remain open. Additionally, the bypass damper will open, sending excess supply air back into your return and lowering static pressure.
Written down below are the amazing advantages that you can experience from installing bypass dampers in your HVAC system.
Goodbye to wasted energy. The amazing advantage of bypass dampers for zonal HVAC systems is that you have complete control over how conditioned air is distributed. The duct dampers are shifted by zone controllers, restricting airflow to unwelcome places. Having a large number of thermostats can provide some of this capability. That is why installing bypass dampers in your HVAC system is pretty important as it can give you the chance to save a lot of money from your electricity bills.
During the cooling season, occupant comfort and well-being will improve since the zone humidity will be better controlled than with a traditional constant volume system. Furthermore, even in the dehumidification mode of operation, because return air bypass comprises completely modulating damper control, extreme zone temperature swings will not occur.
Promotes A Healthy Environment
We all know that humid places have a higher chance to develop mold, bacteria, fungi, and other allergens that are not good for your family’s health. Installing bypass dampers in your HVAC system can assure you that the humidity of your room will be handled well to the point that it will reduce the chance of allergens and mold build-up.
Air Quality Improvement
Because high relative humidity conditions will be better regulated, indoor air quality will improve. Humidity that is out of control can cause condensation inside the building, as well as wood decay, paper deterioration, and mold and microbial growth.
Because occupants will spend less time regulating the zone temperature or using auxiliary sources of cooling (i.e. personal fans) to compensate for the uncontrolled humidity, occupant productivity will increase.
