Title:
A FAN SPEED CONTROL METHOD FOR CALORIC HEAT PUMP SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2020/143586
Kind Code:
A1
Abstract:
A method for operating a caloric heat pump system includes changing a cycle frequency at which a field of a field generator is applied to caloric material in the caloric heat pump system. The method also includes adjusting a speed of a hot side fan in response to the cycle frequency change and adjusting a speed of a cold side fan in response to the cycle frequency change. A respective one of three separate control loops changes the cycle frequency, adjusts the speed of the hot side fan, and adjusts the speed of the cold side fan.
