Air conditioner and pipeline anti-freezing control method and device thereof

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 ...

Problems solved by technology

[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 are very inconvenient to implement, and manual adjustment is required. Manual adjustment for anti-freezing will lead to inability to replace the adjustment logic accurately and in time, which will waste power and fail to achieve the purpose of energy saving
