Embodiment 1

[0023] Embodiment 1. A refrigerator start-up control method in this embodiment includes a compressor start-up control method and a fan start-up control method. The compressor start-up control method includes the following steps:

[0024] S01. The compressor is started at the starting frequency P1, wherein P1 is greater than 0 and less than the maximum frequency of the compressor;

[0025] S02. Increase the frequency of the compressor from the starting frequency P1 to the transition frequency, and finally increase to the normal frequency after a specified period of time. The transition frequency is at least one, and the transition frequency is set between the starting frequency and the normal frequency, so as to Incremental mode transition; see figure 1 As shown, in this embodiment, by setting a transition frequency P2, the compressor starts at the starting frequency P1 for a certain period of time, then increases to the transition frequency P2, and then runs at the transition ...

Abstract

The invention discloses a refrigerator start-up control method, including a compressor start-up control method and a fan start-up control method. The compressor start-up control method includes the following steps: (a1), the compressor is started at a start-up frequency P1; (a2) 1. Increase the frequency of the compressor from the starting frequency P1 to the transition frequency, and finally increase to the normal frequency after a specified time; the fan startup control method includes the following steps: (b1), the fan starts at the startup speed H1; (b2 ), increase the speed of the fan from the starting speed H1 to the transition speed, and finally increase to the normal speed after a specified time. The start-up control method of the refrigerator of the present invention effectively reduces the start-up noise of the compressor and the start-up noise of the fan, avoids the resonance noise caused by the simultaneous start-up of the condensing fan and the refrigeration fan, and improves the cooling effect.

Description

technical field [0001] The invention relates to a method for controlling the startup of a refrigerator, in particular to a method for controlling the startup of a refrigerator compressor and a fan. Background technique [0002] In the existing refrigerator start-up control method, the start-up control of the variable frequency compressor is generally set by setting a start-up frequency (for example, 80% of the maximum frequency of the variable-frequency compressor), and at the initial operation, by limiting the frequency of the variable-frequency compressor to increase it to start After the specified time, make it run at the target frequency, which can prevent the home appliances from being unable to start normally due to the long-term preheating state. However, when the set starting frequency is higher than the target frequency, the starting noise will be very loud, which affects the performance of the product. For example, the frequency range of the refrigerator is 53Hz, ...
