Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a rapid defrosting device for air source heat pumps. Background Art

[0002] Air source heat pump, as a kind of heat pump technology, has the reputation of "the transporter of nature's energy", and has multiple advantages such as low cost, easy operation, good heating effect, safety and cleanliness. It uses the energy in the air as the main power, drives the compressor to operate through a small amount of electricity to achieve energy transfer, does not require complex configuration and special machine room, can reduce the large amount of pollutant emissions brought by traditional heating to the atmospheric environment, ensures heating effect while taking into account the purpose of energy saving and environmental protection, so it is widely used as solar auxiliary heating equipment;

[0003] A Chinese patent with publication number CN219624314U was searched and found to have disclosed an air source heat pump rapid defrosting device.

[0004] The above technical scheme includes: an evaporator, a scraper, a motor, a first shaft, a second shaft and two belts. The evaporator is composed of a base frame and a plurality of fins in the base frame that are equally spaced. The scraper slides on the base frame along the extending direction of the fins to clean the gaps of the fins. The first shaft and the second shaft driven by the motor are rotatably mounted on the base frame on both sides of the fins and are located on the same plane. The two belts are parallelly mounted at both ends of the first shaft and the second shaft. The two belts are fixedly connected to both ends of the scraper, respectively, to solve the problem in the prior art that the fin-type radiator is used as an evaporator. After heating and defrosting, liquid is easily retained between the fins. The retained liquid is very likely to frost during use, which accelerates the frost formation rate and even causes damage to the fins.

[0005] However, in the above scheme, the technology uses a scraper to remove water or frost on the fins, but the fins are very thin and light, and the scraper needs to contact the fins during the defrosting process, which can easily cause the fins to deform or break. Fin frost is condensed water condensing on the surface of the fin. After the frost is scraped off, it will still adhere to the equipment and affect the operation of the equipment.

[0006] To this end, we propose an air source heat pump rapid defrosting device. Utility Model Content
