What EWC Controls Bring To The Table In Terms Of Air Quality

By Coleen Torres


Research shows that air quality is considered by many as one of the biggest determinants of comfort inside a building. People rely on HVAC systems to maintain the quality of air as high as possible. There is an accepted percentage of air quality that any people consider comfortable, and this is what many systems aim at. They achieve this through zoning, which is one of the aspects that EWC controls strive to achieve and specialize in.

In zoning, the house or building is divided into numerous zones. In each of these zones, there are thermostats that control the temperatures of a specific area. The thermostats are controlled by a central operating system. After setting the desired temperatures for the different sectors, the zoning system will maintain them as they are.

A single thermostat can be effective at times but might cause discomfort. The thermostat sets a single constant temperature for the whole house, which might not always be appropriate because the conditions for each room in the house sometimes require different temperature settings. With a blanket temperature, there might be a situation where one is comfortable in one area of the house and uncomfortable in another.

The need to make constant adjustments as one moves from one room to another is never present with the zoning system. Zoning is very efficient. Using a single thermostat is very tedious with the changes that have to be made. Using an air conditioning system can be very expensive, because they often consume a lot of electricity.

But temperatures are not the only component of an efficient system. The quality of circulating air is also important, and this is controlled by dampers. There are many types of dampers, like the curtain fire, insulated fire, and multi-blade fire dampers. They work by controlling the flow of air in HVAC systems, thus regulating such aspects as the temperature, humidity, and aeration.

There are other components of air quality that are important. Things like aeration and humidity are controlled by dampers. There are numerous types in the market, like insulated fire and multi-blade fire types. They control the flow of air into and out of a room, and work together with the typical temperature zoning systems. The dampers control the temperature, humidity, as well as aeration of rooms.

Dampers are especially famous in large buildings, where using a zoning system might be unrealistic or an air conditioning system for each room is too expensive. They are a cheap way of achieving HVAC control. They work by controlling those aspects of circulating air that are absolutely necessary but which a temperature zoning system cannot necessarily control. Dampers come in both manual and automatic types, some of which do not even need the initial settings of temperature because they self regulate.

There are many advantages of zoning systems in HVAC. They help the house owner achieve the comfort zone. This is the level of circulating air quality that scientists have determined to be comfortable for about 80 per cent of typical building occupants. They are cheap and comfortable, reducing the energy expenditure while improving the comfort of occupants in an office or a home. Poor quality of internal air circulation is also bad for health of people. It might make it easy to contract airborne diseases or affect the health of the elderly and very young kids.
