The function of the economizer is, as its name implies, to "economize" or save on cooling costs. Obviously, it costs money to operate the compressor. If the compressor can be shut down and the system still provide adequate cooling, energy savings can be realized.Heat internal to the building, such as people, lights, computers, copy machines, motors, and other machines, causes the temperature inside a structure to increase. Heat soaked up by the building structure may also continue to heat the building long after the temperature outside the building has dropped. There are times when the temperature outside a building is lower than the temperature inside.
Whenever the HVAC system is calling for cooling and the temperature outside is cool enough, it is economical to shut off the compressor and bring in cool outside air to satisfy the cooling needs of the building. Questions on HVAC terms? Give us a call today: 239-596-5855.
