Problems solved by technology

In fact, the appropriate cooling capacity demand of the compressor is not only related to the ambient temperature, but also includes the load changes of the refrigerator itself, such as opening the refrigerator door or putting in loads, etc. Therefore, it is difficult fo

Example Embodiment

[0035] In this embodiment, such as figure 1 As shown, a refrigerator frequency conversion control method is carried out as follows:

[0036] Step 1: Set the target operating rate of the refrigerator η 0 , Target availability η 0 It is the ideal starting rate of the refrigerator, the value range is 40%-100%; the refrigerator is powered on for the first time, and the compressor runs at the highest speed;

[0037] Step 2: When the compressor runs to the (N+1)th shutdown, obtain the average startup rate η of the refrigerator for N consecutive startup and shutdown cycles through equation (1) i :

[0038] η i =Compressor cumulative running time / total time (1)

[0039] Step 3: The average start-up rate η of the previous N consecutive start-stop cycles i And target availability η 0 For comparison, the adjustment coefficient K is obtained by formula (2) i :

[0040] K i =η i / η 0 (2)

[0041] Step 4: Obtain the operating speed S of the compressor at the next startup by formula (3) i :

[0042]...

Abstract

The invention discloses a refrigerator frequency conversion control method and an application thereof. The refrigerator frequency conversion control method and the application thereof are characterized in that when a refrigerator is powered on for the first time, a compressor of the refrigerator runs in the highest frequency, starting rate of first N starting and stopping cycles of the compressor is calculated after the compressor continuously runs for N+1 starting and stopping cycles, and running frequency of the next start of the compressor is determined according to presupposed target starting rate. The refrigerator frequency conversion control method and the application thereof can fully play the advantage that rotational speed of compressor is alterable, enable the refrigerator to achieve the purposes of noise reduction and energy conservation.

Description

technical field [0001] The invention relates to a refrigerator frequency conversion control method and an application thereof, belonging to the field of refrigerator control. technical background [0002] Refrigerator compressors are divided into fixed frequency compressors and variable frequency compressors. Fixed-frequency compressors have rich product types, mature technology, and are widely used, but their frequency cannot be changed, and the cooling capacity is a fixed value under certain working conditions; variable-frequency compressors can change their speed and thus change the cooling capacity of the compressor. Under normal conditions, the compressor can run at high speed, and the refrigerator can quickly cool and cool down. Under low load or stable conditions, the compressor can maintain low-speed operation. The refrigeration system has high efficiency, effectively reducing the frequency of compressor startup and shutdown, and making the temperature fluctuation in...
