Economizer Cooling – Trane Commercial HVAC Help Center
Economizer Cooling. Symbio™ 700 supports a 0 to 100% economizer damper which requires a discharge air temperature sensor to be installed for economizer cooling. There are four configurable economizer types: fixed dry bulb, differential dry bulb, reference enthalpy, and comparative enthalpy. Each type, enable, and the
In this mode, the economizer system adjusts both the outdoor- and return-air dampers, modulating these airflows to match cooling capacity with cooling load—without mechanical cooling. Intake airflow varies between the minimum setting and a maximum value (100% of supply airflow) to maintain the supply-air (or space) temperature at setpoint.
operation of an airside economizer—a device used to conserve mechanical cooling energy and reduce operating costs. This EN reviews the economizer requirements of ASHRAE Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings,the newest version of the popular energy standard, with a focus on airside economizers.
