System and Method for Optimizing Energy Consumption in an HVAC Unit by Minimizing Chiller Activity

摘要

A system and method that optimizes energy consumption in an HVAC unit by minimizing chiller activity. The system uses a control unit that overrides a thermostat in at least one room to close a cooling valve that leads a fluid input to the room. When multiple cooling valves are closed through the rooms, the consequential return fluid maintains greater cooling capacity and thus, the chiller does not have to operate at full capacity. The control unit individually controls components in the HVAC unit, which were previously controlled by switches on the thermostat. The control unit includes a temperature sensor that monitors an environment, such as the room and a plenum. The control unit also includes a control relay that closes the cooling valve on the HVAC unit when the predetermined temperature of the control unit is above the thermostat temperature set by a room occupant.

主权项

1. A system that optimizes energy consumption in an HVAC unit by minimizing chiller activity that uses a control unit to override a thermostat in at least one room, the system comprises:
at least one control unit that retrofits into at least one room, each control unit having a temperature sensor that monitors an environment to ensure that the at least one room is maintained within a range of a predetermined temperature; and at least one control relay that controls a cooling valve, each control relay is a part of the control unit and at least one control relay closes the cooling valve at the predetermined temperature that is above a manually set thermostat temperature.
