Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific examples are only used to explain the present invention, but not to limit the present invention.

[0024] The refrigerator refrigerant leakage detection method proposed by the present invention comprises the following steps:

[0025] Firstly, the temperature drop rate of the evaporator outlet of the refrigerator within a set time corresponding to different ambient temperatures and different amounts of refrigerants is determined through experiments;

[0026] Then, calculate the actual temperature drop rate of the evaporator outlet within the set time according to the different operating stages of the refrigerator;

[0027] According to the comparison result of the actual temperature drop rate and the temper...

Abstract

The invention discloses a refrigerator and a refrigerant leakage detection method thereof. The refrigerator refrigerant leakage detection method includes: determining the drop rate of the outlet temperature of the evaporator within a set time corresponding to different ambient temperatures and different amounts of refrigerant; calculating the temperature drop rate of the evaporator outlet within the set time according to different operating stages of the refrigerator The actual temperature drop rate; according to the comparison result of the actual temperature drop rate and the evaporator outlet temperature drop rate determined by the test, it is judged whether there is refrigerant leakage in the refrigerator. The invention can quickly detect refrigerant leakage, remind users in time, facilitate after-sales maintenance, and eliminate potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a refrigerant leakage detection method thereof. Background technique [0002] With the popularity of smart refrigerators, the functions of refrigerators are becoming more and more abundant. During the use of the refrigerator, refrigerant leakage occurs from time to time. If the refrigerant leakage is serious, it will seriously affect the cooling effect of the refrigerator. At present, the refrigerator industry does not have a good method for detecting refrigerant leakage. The reason is that the leakage of refrigerant cannot be judged intuitively, and it is not easy for users to detect it. Once a refrigerator refrigeration problem is found, it is checked for refrigerant leakage. In addition, more importantly, refrigerants are flammable and explosive items. If the refrigerant leaks, it will cause major safety hazards. [0003] Therefore, how to quickly de...
