The heat pump is an efficient energy-saving device that makes full use of low-grade heat energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but it cannot spontaneously proceed in the opposite direction. The working principle of the heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle energy and can obtain a large amount of heat supply, which can effectively use low-grade products that are difficult to apply. Finally, the purposes of saving energy are achieved. This article mainly relates to the patents of high-power heat pumps, compact heat pumps, and split heat pumps, this article discusses from three aspects: high power, split and compact heat pumps. In the hope that reflect the novelty, it mainly discusses the relevant patent documents in the past five years.
