Abstract

The invention relates to the field of refrigeration control, in particular to a multi-system refrigerator fan energy-saving control method, a controller, a readable medium and a refrigerator. The multi-system refrigerator fan energy-saving control method comprises the steps that when a refrigerating chamber is started each time, the initial temperature T0 of an intra-refrigerator temperature sensor of a next system which is in series connection with the refrigerating chamber is acquired, and the temperature T1 of the sensor is acquired at the moment of the shortest waiting time of a fan of thenext system; the temperature T1 is compared with the initial temperature T0, the temperature difference is calculated, and whether the fan of the next system is started or not is determined accordingto the temperature difference value; and temporary stop of the rotation speed of the corresponding fan is conducted. The rotation speed of the fans is selected automatically; the influence that in the working process of the refrigerating chamber, the intra-refrigerator temperature of the next system is raised is avoided; and meanwhile, the effect of energy consumption reduction is achieved.

Description

technical field [0001] The invention relates to the field of refrigeration control, in particular to a multi-system refrigerator fan energy-saving control method, a controller, a readable medium and a refrigerator. Background technique [0002] In the existing multi-system air-cooled refrigerator, multiple systems are connected, and the work affects each other. For example, during the working process of refrigeration, in addition to the normal control of the fan in the refrigerator room, the fans in the system connected in series with the refrigerator room will also be turned on. Room cooling. [0003] In the existing system, due to the normal cooling process of the refrigerator, the evaporation temperature of the refrigeration system is relatively high. After the refrigerant passes through the refrigerator, it then enters other systems connected to the refrigerator, and the evaporation temperature will further increase, sometimes higher than that of the latter system. The ...
