Abstract

The invention discloses a defrosting method of an intelligent comprehensive defrosting device for an air source heat pump unit. The defrosting method comprises an automatic defrosting mode, a manual defrosting mode and a humidity defrosting mode. The defrosting method of the intelligent comprehensive defrosting device for the air source heat pump unit has the beneficial effects that a single chip microcomputer which is more stable in performance and a high-quality collection and detection transmitter are adopted, and defrosting control is conducted comprehensively through PHT (temperature, humidity, pressure and time) and the peculiar calculation mode; defrosting efficiency is improved; and energy is saved.

Description

technical field [0001] The invention relates to a defrosting device and a defrosting method thereof, in particular to an intelligent comprehensive defrosting device of an air source heat pump unit and a defrosting method thereof. Background technique [0002] Air source heat pump units have a wide range of markets, and its defrosting technology has been valued by various manufacturers because it involves key indicators such as energy saving and heating efficiency. Defrost technology has always been a major problem. At present, temperature detection and control are mostly used in the market, resulting in inaccurate control accuracy and methods. Under low temperature and high humidity conditions, the defrosting efficiency is low or even no defrosting or the defrosting time is too long, which greatly affects the Air source heat pump heating performance and waste energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
