Abstract

The invention discloses a method for adjusting the rotation speed of a draught fan of an air cooling refrigerator. In the method for adjusting the rotation speed of the draught fan of the air cooling refrigerator, after the draught fan is started, the descent rate of the temperature of an outlet of an evaporator is acquired through calculation; and according to the descent rate of the temperature of the outlet of the evaporator, the rotation speed of the draught fan is adjusted. The invention further discloses the air cooling refrigerator. By the adoption of the method and the air cooling refrigerator, the rotation speed of the draught fan of the air cooling refrigerator and the cooling capacity output of a compressor are efficiently matched, and the use efficiency of cooling capacity is improved.

Description

technical field [0001] The invention relates to the field of fan speed control, in particular to a method for adjusting the fan speed of an air-cooled refrigerator and an air-cooled refrigerator. Background technique [0002] The air-cooled refrigerator uses a fan to circulate the cold air generated by the evaporator, so as to achieve the purpose of cooling. Air-cooled refrigerators have an automatic defrosting function, are easy to use, and are more and more popular among the public. However, in the air-cooled refrigerators on the market, the fan speed is usually set to a fixed frequency or a fixed frequency of several segments, and the fan speed and the cooling capacity output of the compressor do not achieve an efficient match, resulting in low utilization efficiency of the cooling capacity. Contents of the invention [0003] The main purpose of the present invention is to provide a method for adjusting the fan speed of an air-cooled refrigerator and an air-cooled refr...
