Control of reversible heat pump assembly for heating and cooling
A recently granted patent (Publication Number: US11874014B2) discloses a controller designed to manage a reversible heat pump assembly's operation in either heating or cooling mode. The controller includes a control circuit that utilizes various functions to determine heating and cooling demands, identify simultaneous demands for both modes, and generate control signals to adjust the heat pump's output accordingly. By temporarily increasing the heat pump's output in response to simultaneous demands, the controller effectively reduces the duty cycle for heating or cooling, optimizing energy efficiency. The control circuit also delays mode changes based on duty cycle thresholds, ensuring efficient operation of the reversible heat pump assembly.
Furthermore, the patent describes methods for controlling the reversible heat pump assembly, emphasizing the importance of balancing heating and cooling demands to enhance overall performance. By incorporating time-resolved information on heating and cooling desires, the controller can efficiently manage the heat pump's operation. Additionally, the methods involve receiving demand inputs from local heating and cooling circuits connected to the assembly, further enhancing control precision. The patent also introduces the concept of assigning priority levels to heating and cooling demands, allowing the controller to prioritize specific demands based on their importance, thereby optimizing the system's overall efficiency and performance.
