US 2016/0348936 A1 · TEMPERATURE CONTROL SYSTEM AND METHODS FOR OPERATING SAME

Abstract

A method for operating a temperature control system having a cooling system and ventilation system to vent outside air within a structure is disclosed. The method includes monitoring an interior temperature of the structure, monitoring an exterior temperature of ambient air outside of the structure, defining a first time range and a second time range, associating one or more operating parameters of the temperature control system with the first time range, associating one or more operating parameters of the temperature control system with the second time range, monitoring operational time and operational load of the cooling system for the first time range, predicting a space temperature and an outdoor air temperature for a subsequent time period, and controlling the ventilation subsystem during the second time range based upon the monitored operational time and operational load of the cooling subsystem for the first time range, the monitored interior and exterior temperatures, the predicted space temperature, the predicted outdoor air temperature, and the one or more operating parameters of the cooling subsystem associated with the second time range.
