Embodiment 1

[0035] Such as figure 1 As shown, a method for controlling the start-stop temperature point of a refrigerator compressor according to the present invention specifically includes the following steps:

[0036] S1. Determine the temperature compensation value in different gears according to the ambient temperature range.

[0037] S2. Determine the start-stop tolerance of the refrigerator compressor according to the ambient temperature range. The start-stop tolerance refers to the difference between the preset start-up temperature point and the preset stop temperature point of the compressor.

[0038] S3. According to the temperature compensation value and the start-stop tolerance, determine the actual start-up temperature point and the actual stop temperature point of the compressors of different gears in the ambient temperature range.

Embodiment 2

[0048] A specific embodiment of the present invention, a method for controlling the start-stop temperature point of a refrigerator compressor, comprising the following steps:

[0049] S1. Determine the temperature compensation value in different gears according to the ambient temperature range.

[0050] In this step S1, the method for determining the temperature compensation values ​​at different gears is the method of approximating the central point of the eigenvalue.

[0051] Such as figure 2 As shown, first check whether it is a test model of the refrigerator, and if it is not a test model, perform temperature compensation according to a fixed compensation value. If it is a test model, run the test machine refrigerator according to the default parameters (default start-up temperature point and shutdown temperature point) for the first time (time1). After the refrigerator is stable, start collecting the average temperature T_ROM of the upper, middle and lower points in the...

Embodiment 3

[0107] Refer to the attached Figure 8 Describe a refrigerator compressor start-stop temperature point control device 100 according to an embodiment of the present invention, including: a temperature compensation module 101, used to determine the temperature compensation value at different gears according to the ambient temperature range; a start-stop tolerance module 102, It is used to determine the start-stop tolerance of the refrigerator compressor according to the ambient temperature range. The start-stop tolerance refers to the difference between the preset start-up temperature point and the preset stop temperature point of the compressor. The actual start-stop point determination module 103 is used to determine the actual start-up temperature point and the actual stop temperature point of the compressor at different gears in the ambient temperature range according to the temperature compensation value and the start-stop tolerance.

Abstract

The invention discloses a method and device for controlling the start-stop temperature point of a refrigerator compressor, and the refrigerator. The method includes the following steps: determining the temperature compensation value at different gears according to the ambient temperature range; determining the compressor compression value according to the ambient temperature range The start-stop tolerance of the machine, the start-stop tolerance refers to the difference between the preset start-up temperature point and the preset stop temperature point of the compressor; according to the temperature compensation value and the start-stop tolerance, determine the different gears under the ambient temperature range The actual start-up temperature point and the actual stop temperature point of the compressor. The advantages of the present invention are: first, the present invention can intelligently adjust the start-stop temperature point of the compressor of the refrigerator tester before mass production, and find the best parameters of the refrigeration system; secondly, because the adjusted start-stop temperature point is closer to the actual use process, thereby improving the work efficiency of mass-produced refrigerators.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a method and device for controlling the start-stop temperature point of a refrigerator compressor and a refrigerator. Background technique [0002] Before the current mass-produced refrigerators reach mass-production status, repeated experiments are required to finally determine a set of parameters that match the system. However, with the differences in production assembly and the loss of the practical environment, the parameters during mass production may no longer be the best matching parameters, which will definitely affect the efficiency of the refrigerator. Contents of the invention [0003] The purpose of the present invention is achieved through the following technical solutions. [0004] The invention proposes an adaptive intelligent control method, by comparing the average value of the refrigerator testing machine running for a per...
