Embodiment Construction

[0020] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0021] Such as figure 1 The method for realizing precise and efficient temperature control of a refrigerator includes the following steps:

[0022] S11, according to the set temperature of the compartment and the actual collected temperature of the compartment, the cooling capacity requirement of the compartment is determined;

[0023] The step S11 is specifically as follows: the set temperature of the compartment is T1, and the actual temperature T2 of the compartment is collected through a temperature sensor whose accuracy is 0.1°C. Cooling capacity of the required compressor output) is COP x , through the function COP x =∫(T1, T2). For example, under the conditions of T1=8°C and T2=10°C, it is calculated that △Tf=(10°C-8°C)=2°C, and in the state of the current temperature change rate △Tb=1, look up Table 1 and get COPx=85W .

Abstract

The invention discloses an accurate and efficient temperature control implement method for a refrigerator. The method comprises the following steps that judgment is conducted to obtain a chamber cooling capacity requirement according to setting temperature and actually collected temperature of chambers; the motions of fans and air doors of the chambers are controlled according to the chamber cooling capacity requirement; chamber cooling capacity, rotating speeds of the fans and opening angles of the air doors are stored in a one-to-one correspondence mode. The accurate and efficient temperature control implement method has the advantages that the temperature control accuracy of the chambers and operation efficiency of a whole machine are improved; the noise generated by rotation of the fans in the cooling process is lowered. Therefore, the fresh-keeping and energy-saving effects of the refrigerator are improved.

Description

technical field [0001] The invention relates to a method for controlling the temperature of a refrigerator, in particular to a method for realizing accurate and efficient temperature control of a refrigerator. Background technique [0002] In today's society, the pace of life is accelerating, and the number of times consumers purchase food is gradually decreasing, but the amount of purchases is increasing. Generally, consumers shop once a week. If they purchase such a large amount of food, they need the freshness of the refrigerator. it is good. [0003] Air-cooled refrigerators are favored by consumers for their advantages of no frost, precise temperature control, and uniform cooling. However, air-cooled refrigerators also have disadvantages such as excessive noise and high power consumption. Contents of the invention [0004] The invention overcomes the shortcomings of excessive noise and high power consumption in the use process of the air-cooled refrigerator in the pr...
