MULTIPLE ZONE CONTROL SYSTEM AND METHOD OF OPERATION

摘要

A multiple heating/cooling zone control system is disclosed. A heating/cooling system control device continuously monitors heating/cooling zone demand and matches the heating/cooling device output capacity to the total space or heat input required. Within the calculated heating/cooling device output capacity the heating/cooling device is modulated based on zone temperature setpoint to further adjust heating/cooling device output. As heat/cooling loss is increased heating/cooling device capacity and modulation are increased. Should heat/cooling loss decrease heating/cooling device capacity and modulation are decreased. Since heat/cooling output is adjusted based on the heat loss(gain) the heating/cooling device can be immediately adjusted to the proper or matching heating/cooling rate even before water/air temperature based adjustments can be made. Hence, the overall effect of the control device is a reduction in cycles of the heating/cooling device and the life of the heating/cooling device is extended and subsequent energy is saved.

主权项

1. A method for controlling a multiple zoned heating/cooling system, the method comprising:
establishing a heating/cooling demand for multiple individual zones; communicating to a controller active zones which require heating/cooling; summing the total heating/cooling demand required by the active zones; establishing a maximum heating/cooling rate based on the total heating/cooling demand required by the active zones; establishing the type of heating/cooling radiation type associated with heating/cooling demand; communicating to the controller active heating/cooling radiation type; establishing a target temperature setpoint based on active heating/cooling radiation type; setting a heating/cooling rate based on measured temperature, target temperature setpoint and a maximum heating/cooling rate.
