Control method of refrigerator applicable to high-temperature environment

Abstract

The invention relates to a control method of a refrigerator applicable to a high-temperature environment. The refrigerator comprises a refrigerating chamber and a chilling chamber, wherein the chilling chamber is internally provided with a compressor, a fan and a chilling temperature sensor; the chilling chamber is internally provided with a refrigerating temperature sensor; an air flue between the refrigerating chamber and the chilling chamber is internally provided with an air door; the compressor, the fan, the air door, the chilling temperature sensor and the refrigerating temperature sensor are connected with a control board arranged in the refrigerator; and the control method comprises the following steps that the control board selects a control mode of the refrigerator to be a common mode or a delaying optimized mode according to a chilling temperature detected by the chilling temperature sensor and then converts into the common mode. According to the control method disclosed by the invention, delaying optimized control is adopted at a high-temperature environment, and chilling and refrigerating load peak values are staggered, so that the total load peak value of the system is reduced, and the normal starting and operation of the compressor are guaranteed. Furthermore, on the premise of not increasing the cost, the starting and operation problems of the refrigerator under the high-temperature environment are solved, so that the stability and reliability of using the refrigerator are improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a method for controlling refrigerators suitable for high-temperature environments. Background technique [0002] In modern life, on the one hand, consumers have higher and higher requirements for the use of refrigerators, and on the other hand, the use environment and conditions of refrigerators are becoming more and more diversified. This requires that the refrigerator can not only be used normally under ordinary and normal conditions, but also should be able to operate normally under severe conditions. For example, in a high temperature environment (high load condition), abnormal voltage fluctuations, etc. And often under the above-mentioned severe conditions, the load of the refrigerator system will exceed the normal bearing range of the compressor, which will cause start-up and operation failure and instability, thus causing the refrigerator to not be used normally.
