Abstract
Official abstract text for this publication.
A method for reducing perceived defrost noise in a heat pump is provided. The method may include energizing a fan configured to urge a heat transfer medium across a heat exchanger, and initiating a defrost cycle to warm the heat exchanger. Initiating the defrost cycle may include de-energizing a compressor fluidly coupled to the heat exchanger, and delaying for a first delay period with the fan energized and the compressor de-energized. Initiating the defrost cycle may also include energizing a reversing valve after the first delay period, to reverse a flow of a refrigerant flow between the compressor and the heat exchanger, and delaying for a second delay period with the fan energized, the compressor de-energized, and the reversing valve energized. Initiating the defrost cycle may also include de-energizing the fan. The method may also include defrosting the heat pump during the defrost cycle, and terminating the defrost cycle.
