Embodiment Construction

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0046] figure 1 It is a flow chart of an air-conditioning pipeline antifreeze control method provided by an embodiment of the present invention. Such as figure 1 As shown, an air-conditioning pipeline anti-freezing control method includes:

[0047] 110. Obtain the operating state of the unit, and obtain a temperature parameter reflecting the water temperature in the pipeline when the unit is in a shutdown state.

[0048] Specifically, in this embodiment, the temperature parameter includes any one of ambient temperature, water inlet temperature and water outlet temperature. Such as detecting the ambient temperature. The ambient temperature, the water inlet temperature and the water outlet temperature can all refl...

Abstract

The invention relates to an air conditioner and a pipeline anti-freezing control method and device thereof. The pipeline anti-freezing control method includes the steps that the running state of a unit is acquired, and a temperature parameter reflecting the temperature of water in a pipeline is acquired in the shutdown state of the unit; and when the temperature parameter is lower than a preset anti-freezing temperature, a water pump on the pipeline and an electric heater additionally arranged on the pipeline are started. The pipeline anti-freezing control method achieves that under the situation that the unit is not used, the situation that the water in the pipeline ices when the air temperature is too low is avoided in a simple, safe and efficient manner, and especially it is avoided that water in a heat exchanger ices, the volume expands, and the heat exchanger is damaged.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and its pipeline antifreeze control method and device. Background technique [0002] In winter, air-conditioning pipes are prone to freezing and freezing. There are many types of antifreeze measures that can be taken in the existing technology, and you can choose according to your own conditions: one is to add ethylene glycol antifreeze to the water supply system pipeline according to an appropriate ratio; Drain the water completely. [0003] In the above method, there are the following disadvantages and deficiencies: the user needs to add antifreeze by himself, and the amount of antifreeze added depends entirely on the user's feeling; the user needs to manually release the water in the system pipeline when not in use, and it cannot ensure that the amount of antifreeze in the management of water is completely drained. [0004] The above two methods ...
