Abstract

The invention provides an anti-freezing device, a control method thereof, a heat pump unit and an air conditioner. The anti-freezing device comprises a heating part, a to-be-anti-freezing part and a heat exchange part; the heating part is provided with a fluid outlet, the heat exchange part is provided with a heat exchange inlet, and the heat exchange inlet communicates with the fluid outlet through a pipeline; and the pipeline is used for guiding fluid heated by the heating part to enter the heat exchange part, and the heat exchange part is used for carrying out heat exchange on the fluid heated by the heating part and the to-be-anti-freezing part. According to the anti-freezing device, the control method thereof, the heat pump unit and the air conditioner, the problem that the unit is prone to freeze in a low-temperature environment is effectively solved.

Description

technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to an antifreeze device and a control method thereof, a heat pump unit and an air conditioner. Background technique [0002] At present, due to the limitation of installation conditions and the noise of the water pump, the indoor unit of the split heat pump water machine needs to be installed outdoors together with the outdoor unit under certain conditions. [0003] However, in the low temperature environment in winter, in the indoor unit installed outdoors, some mechanisms or components with low flow rate and small pipe diameter, such as the corresponding pipeline of the expansion tank, drainage pipeline, water supply pipeline, etc., may freeze The risk of freezing and cracking inside the pipeline will cause the water in the system to flow into the refrigerant system in severe cases, causing the whole machine to be scrapped. [0004] Therefore, how to provid...
