Abstract

The invention discloses a heat pump system and a defrosting control method of the heat pump system. The heat pump system comprises a compressor, an outdoor side heat exchanger and indoor side heat exchangers. The compressor, the outdoor side heat exchanger and the indoor side heat exchangers are connected through a pipeline valve system. The heat pump system further comprises a heat storage module. The heat storage module comprises a heat storage material, a heat exchange pipeline capable of exchanging heat with the heat storage material and a valve device for controlling the refrigerant flow in the heat exchange pipeline. The heat exchange pipeline is connected with the pipeline valve system, and the heat exchange pipeline is connected with the indoor side heat exchangers in parallel. In this way, by the adoption of the heat pump system, the problem that in the prior art, when an outdoor side heat exchanger of a heat pump conducts defrosting, it is required to take heat from the inner side of a room, and consequently the comfort of the room is poor is solved.

Description

technical field [0001] The invention relates to the technical field of heat pumps, more specifically, to a heat pump system and a defrosting control method thereof. Background technique [0002] When the outdoor temperature is low, the surface of the outdoor heat exchanger of the heat pump is prone to frosting. Once frost forms on the surface of the heat exchanger, the heat exchange with the outside world will be greatly affected, and then the performance of the heat pump will rapidly decay. [0003] In the prior art, in order to quickly defrost, heat is usually taken from the indoor side, which leads to insufficient heating capacity on the indoor side, making the room less comfortable. [0004] Therefore, how to solve the problem in the prior art that when the heat pump outdoor defrosts, heat needs to be taken from the indoor side, resulting in poor room comfort, has become an important technical problem to be solved by those skilled in the art.
