Must Knows Of An EWC Damper

Must Knows Of An EWC Damper

By Dawn Williams


Too much heat and too less of it is enough to raise your eyebrows and unsettle your nerves. The law of physics involving thermodynamics has solved the problem that has once plagued air conditioning systems. The invention of an EWC damper and draft regulating valves have been a blessing to the modern world. Having the right amount of coolness can be achieved using these pieces of machinery.

A damper or a supply duct opening is a noun which refers to a material that inhibits. It has a wide range of definition according to the areas of engineering, music, and electronics. It adjusts airflow and permits just the right ventilation inside buildings, rooms and engines.

There are rectangle and circle dampers. Circles are more convenient to use because they are easy to install. Their varied sizes are usually sold in mechanical shops. However, rectangles need to be pre-ordered because they have to undergo size determination in a metal fabricator. They are usually a bit complicated to install.

Temperature regulating devices allow draft to go in or to go out. When the room is too cold, they close so that warm air gets trapped which gradually turns the temperature up. When it is hot, they open so the draft gets in and warmer air gets out effecting a decrease in the temperature. They generally act as traffic enforcers in pipes and ducts. You can visually determine the patency of the regulator through its visible chamber and its lever position.

A supply duct opening can be manual or automatic. Manual types need an outside force to open or close their panes. Automatic types have a built in motor that detects any temperature change and immediately adjusts the flow of breeze from the outside to the inside and vice versa.

Dampers are very helpful to prevent fire. They are also installed in furnaces to control combustion. When their panes are open, oxygen is added to the fire which enhances combustion. If the panes are close, which is a protocol when there are fire emergencies, the supply of oxygen becomes limited thus, lessening the strength of the flame.

Being aware of the measurement of your HVAC or heating, ventilating and air conditioning equipment duct is important. It needs to match your airflow controller for easy and proper installment. Some regulators are made for special purposes like to disperse smoke or contain fire in an explosion. Determine what you need so that you will be able to choose the right type for you.

Leakage to the return and supply of air affects the temperature adjustment of your regulator. Mixture of contaminated gas from the outside may also pose a health risk to zone occupants. The amount of space of a zone should not exceed the capacity of the cooling and heating system to avoid problems in ventilation.

Enhancement of products are the concerns of businessmen in this industry as competitors are now increasing in number. This step is also needed to lessen the problems related to an EWC damper or other airflow control devices. The ability to control temperatures of different areas at the same time is a challenge to developers. Customer satisfaction is always put in the line to ensure marketability of heating, ventilating and air conditioning devices and their regulators.
