Problems solved by technology

Therefore, this control method is difficult to meet the frequency control requirements of the inverter compressor of the air-cooled refrigerator.
[0005] It can be seen from the above that the air-cooled refrigerator fails to give full play to the characteristics of the frequency conversion compressor when the frequency control technology of the frequency conversion compressor has been disclosed.

Embodiment Construction

[0028] In this example, if figure 1 As shown, a method for controlling the frequency of an air-cooled refrigerator is carried out in the following steps:

[0029] Step 1. When the air-cooled refrigerator enters the first refrigeration cycle after defrosting, set the speed of the compressor in the first refrigeration cycle to be S i+1 , and S i+1 = S i +K 4 , where S i is the speed of the compressor before defrosting the air-cooled refrigerator, K 4 It is a constant, the value range is 0-2000;

[0030] Step 2. In the first refrigeration cycle after the defrosting of the air-cooled refrigerator, judge whether the continuous operation time of the compressor is ≥ t1 minutes. If it is true, update the speed of the first refrigeration cycle to S (i+2) , and S (i+2) = S (i+1) +K 3 , until the end of the first refrigeration cycle, go to the next step, otherwise, go to step 3 directly; where, S (i+1) is the speed of the compressor before updating, K 3 is a constant, K 3 The...

Abstract

The invention discloses an air-cooled refrigerator frequency conversion control method and an electric refrigerator adopting the same. The air-cooled refrigerator frequency conversion control method and the electric refrigerator adopting the same are characterized in that in a first starting and stopping period after air-cooled refrigerator defrosting, a compressor runs at a high rotary speed; in a second starting and stopping period after defrosting, the compressor runs at a rotary speed before defrosting; and after the compressor continuously runs for (N+1) starting and stopping periods, the compressor starting rate is calculated, and according to a preset target compressor starting rate, the compressor running frequency at the next time of starting is determined. According to the air-cooled refrigerator frequency conversion control method and the electric refrigerator adopting the same, the compressor refrigerating capacity can be effectively adjusted in time according to the refrigerator load change, so that the refrigerator runs in an ideal state all the time, temperature fluctuation in the refrigerator can be reduced, and the purposes of low noise and small energy consumption are achieved.

Description

technical field [0001] The invention relates to a frequency conversion control method for an air-cooled refrigerator and a refrigerator using the method, belonging to the field of refrigerator control. Background technique [0002] Refrigerator compressors are divided into fixed frequency compressors and variable frequency compressors. Fixed-frequency compressors are rich in product types, mature in technology, and widely used, but their frequency cannot be changed, and the cooling capacity is a fixed value under certain working conditions. The variable frequency compressor can change its speed and thus change the cooling capacity of the compressor. Under high load, the compressor can run at high speed, and the refrigerator can cool down quickly. Under low load or stable state, the compressor can maintain low speed operation. The refrigeration system High efficiency, effectively reducing the frequency of compressor start and stop, so that the temperature fluctuation in the ...
