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 generally means a thing that constrains. It is a supply duct opening whose operational definition varies accordingly in the fields of music, engineering and technology. Mechanically, dampers are materials that establish balance between hot and cold temperatures.

Dampers can be purchased in two varying shapes. They are available in circles and rectangles. The circle shapes are dominantly used because they are more convenient to install on cooling and heating appliances primarily because of their standard sizes. On the other hand, the rectangles need to be ordered separately because they still need to be processed on metal fabricators for them to be installed.

An airflow regulator is like a traffic officer. It operates primarily by controlling the amount of draft that goes in and out of rooms and closed spaces. It allows the cooler draft to get in and the warmer gas to get out when it is open to make a warm area cool. It should be close when the temperature gets too low so that warm gases do not escape thereby adjusting circulating air to room temperature. Its visible chamber and lever position allow you to determine if it is closed or not.

A damper can be manual or automatic. Manual ones use a lever to control their open and close functions. Automatic versions are motor operated. It can determine the change in room temperature and adjusts accordingly. This property allows consumers to save in the cost of their electricity without the hassle of constantly checking.

Dampers can be safety devices in limiting diffusion of fire. The concept of letting the draft in supports combustion in household furnaces. Closing the valve inhibits outside wind from getting in which in turn limits the extent and strength of the fire.

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.

Common problems that affect your regulator include leakage that leads to overflow and underflow of air. Also the ratio of the zone space and the number of regulators affect the effectiveness of ventilation. Cross contamination of intakes and releases may also prove to be a health hazard.

Product development is being done by companies so that disadvantages of using an EWC damper and other heat and cold regulators can be minimized if not eradicated. Zoning systems are the trend in the HVAC industry which involves the use of dampers in adjusting temperatures of different areas at the same time. Customer satisfaction is always a top priority for HVAC providers.
