Heat pump control system with defrost cycle monitoring |
摘要 |
A control system for controlling a heating system having a heat pump and a source of supplemental heat. The control system monitors the defrost cycling of the heat pump, and when the heat pump is in its defrost cycle for more than a predetermined portion of a heating cycle, the heat pump will be shut down until the outdoor ambient temperature has risen by a predetermined amount or a given interval of time has elapsed. The heat pump is also shut down if the outside ambient temperature falls below a certain level and is automatically reenabled is the outside ambient exceeds a second level. The system results in more efficient operation of the heat pump/supplemental heat system by disabling the heat pump when weather conditions do not favor efficient heat pump operation.
