Embodiment

[0042] refer to figure 1 , figure 1 It is a schematic flowchart of a method for controlling a refrigeration device provided in an embodiment of the present application. Such as figure 1 As shown, the method at least includes the following steps:

[0043] S101: After controlling the start-up of the condensing fan of the refrigeration equipment, detecting whether the condensing fan has a stall failure;

[0044] Specifically, after the refrigeration equipment starts to cool, the condensing fan can be started synchronously with the start of components such as the compressor and the refrigerating fan, or the condensing fan can not be started at the beginning of cooling, but wait until a specific condition is met before starting. In this embodiment, after controlling the start of the condensing fan, it is detected whether the condensing fan stops, which is used as a prerequisite for controlling other components of the refrigeration device in subsequent steps.

Abstract

The invention relates to a control method and device of refrigeration equipment, a controller and the refrigeration equipment. After it is determined that a condensation fan has a stalling fault, a refrigeration fan and a compressor are maintained to operate for a period of time and then are sequentially closed, and therefore the situation that the temperature of a condenser is too high and the system pressure is too large can be avoided, and the refrigeration effect of the refrigeration equipment is maintained to the maximum degree. In addition, after the compressor is closed for a period of time, along with natural heat dissipation, after the temperature of the condenser is reduced to a reasonable range, the compressor is started again, and therefore the refrigeration process can be recovered again, and damage to stored objects is avoided.

Description

technical field [0001] The present application relates to the technical field of refrigeration equipment, and in particular to a control method, device, controller and refrigeration equipment for refrigeration equipment. Background technique [0002] Refrigeration equipment such as a refrigerator with an independent condenser needs to be equipped with a condensing fan to cooperate with the condenser to dissipate heat. When it is necessary to turn on the condensing fan to dissipate heat, if the condensing fan fails and stops, the temperature of the condenser will rise rapidly, causing the system pressure to be too high, which may cause a series of safety problems. Contents of the invention [0003] The present application provides a control method, device, controller and refrigeration equipment for refrigeration equipment, so as to solve the problem that when the condensation fan fails and stops, the temperature of the condenser will rise rapidly and the system pressure wil...
