why use a vav system?
309041
Advantages of VAV systems include the following points: VAV systems are very cost effective from a chilled-water and heating-water-pumping perspective. Because the unit transfers heat to the space using forced convection, the coil heat transfer area required is reduced as compared to a chilled beam.

Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components.

These MERV ratings really do make a difference. Recent studies have shown that, while air filters with low MERV ratings (1-5) will still minimally protect your HVAC system, these low-efficiency filters offer no better pollutant protection than no filter at all. ... However, it's important not to skimp on your air filters.

One reason that AC units go up in attics is because they're cheaper and easier to install. It's a lot simpler for your installer to leave ductwork loose, rather than having to cover it and wind it through floors and walls.

The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run.

Mini-splits are particularly efficient when compared to other HVAC systems, because they “recycle” energy, to some extent. Also, they use electricity instead of burning gas, which can be advantageous.

1. They're very energy efficient. One of the best things ATAG has going for themselves right now is that their offering some amazing energy efficient features. These include a built-in passive flue gas heat recovery device, which squeezes even more energy that's normally lost out through your flue.

Properly installed and commissioned ventilation systems are significantly more effective in improving air quality. Imbalanced systems can decrease the efficiency of an HRV from around 90 percent to around 60 percent, resulting in four times more energy loss.

Depending on the design of the system, an engineer can select one of two types. One type is a series unit, commonly referred to as a constant volume unit. The other type is parallel, which is typically referred to as a variable air volume or VAV unit.

UAD is combining processing power with the converters. The plug ins for there processing power is another cost with them. It's only expensive when you can't afford it.

is definitely much better than non-modular and a cheaper solution than going full modular. Comes with no cables pre-attached. You only attach the ones you need. It is more expensive, but also gives you more options, allowing you to only install the cables you need and keep airflow and cable management to a maximum.
