An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements. Water-side economizers often operate during nightime to take advantage of cooler ambient temperatures.
What is the purpose of an economizer?
Economizer- The device is built in or retrofitted to rooftop equipment. It allows the unit to use outdoor air for cooling, provided the ambient air is below a certain temperature and the humidity is below a certain percentage.
What does an economizer do on a RTU?
In a nutshell, an economizer is a mechanical vent attached to a roof top unit (RTU) that opens to draw-in outside air for cooling a building when the outside air temperature is cool and dry enough.
How are economizers controlled?
Sensible economizers are controlled by the temperature of the air and provide sensors to measure the outside air temperature, return air temperature and the mixed air temperature. Usually there also is a relief damper, relief fan or a remote air damper that exhausts the building air during economizer operation.
What is an economizer and how does it work?
Economizers reduce the amount of work your A/C unit does, prolonging the life of your system. In addition to helping reduce costs, that decrease in wear and tear on your HVAC system means less maintenance, fewer breakdowns and overall, a longer lifespan for your system. Economizers improve indoor air quality through increased ventilation.
How does an economizer improve indoor air quality?
Economizers improve indoor air quality through increased ventilation. Many buildings, especially older ones, weren’t designed with modern ventilation in mind. An economizer can improve air quality by bringing in fresh air and exhausting your building’s stale air.
What are the benefits of an A/C system economizer?
The less your A/C unit runs, the lower your utility bill. Economizers reduce the amount of work your A/C unit does, prolonging the life of your system. In addition to helping reduce costs, that decrease in wear and tear on your HVAC system means less maintenance, fewer breakdowns and overall, a longer lifespan for your system.
Are economizers the Best Kept Secret in the commercial HVAC World?
HVAC economizers have a variety of benefits that may just make them the best kept secret in the commercial HVAC world. In fact, we call economizers “free cooling” in the industry. Here’s why we recommend economizers for our commercial HVAC customers.
