Abstract (en)
[origin: EP3882531A1] Disclosed is a defrosting system, belonging to the technical field of air conditioner defrosting. The defrosting system comprises: an auxiliary water path (2) and a controller (3). The auxiliary water path (2) is arranged on a condenser (4) side. The controller (3) comprises: a first unit (301), which is used for acquiring an ambient temperature; a second unit (302), which is used for acquiring a coil temperature of the auxiliary water path (2); and a third unit (303), which is used for controlling the auxiliary water path (2) to be connected to high-temperature water in a main water path (1) according to the ambient temperature and the coil temperature of the auxiliary water path (2). According to the embodiments, where a heat pump unit does not shut down, the high-temperature water in the main water path (1) can be introduced into the auxiliary water path (2) on the condenser (4) side so as to complete the condenser (4) defrosting operation, thereby ensuring the continuous operation of the heat pump unit and avoiding frequent starting and stopping during defrosting. A defrosting method and an air conditioner are further involved.
