Control system and method for multi-air-door air-cooled refrigerator and refrigerator

Abstract

The invention discloses a control system and method for a multi-air-door air-cooled refrigerator and the refrigerator. The refrigerator comprises a plurality of chambers which share a compressor, an evaporator and a draught fan. Each chamber is provided with an air supply channel which is used for supplying air and provided with one air supply door. The control system comprises a plurality of temperature sensors and a controller. Compared with the prior art, the control system and method for the multi-air-door air-cooled refrigerator and the refrigerator have the advantages that the situation that the air supply doors are opened and closed alternately due to the fact that the chambers request for refrigeration independently is effectively avoided; the full efficiency operating time of the draught fan is increased; the power consumption quantity of the refrigerator is reduced; at the same time, the time for starting up the compressor is shortened; the service life of the compressor is prolonged advantageously; the product competitiveness is promoted; and in addition, the startup temperature and the shutdown temperature of each chamber is adjusted according to an opening transient temperature, corresponding to the last opening moment of the corresponding air supply door of each chamber, of the corresponding air supply door so that the control method can be applicable to multiple temperature zones of each chamber.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control system and a control method of a multi-door air-cooled refrigerator and the refrigerator. Background technique [0002] Multi-temperature zones and multi-functions are one of the development trends in the refrigerator market. In addition to the refrigerator and freezer compartments of conventional refrigerators, multiple compartments with various temperature zones will also be designed to meet the needs of various consumers. In order to save the cost of refrigerators, air-cooled refrigerators often use a single-fan single-refrigeration system, and control the air volume of each room through multiple dampers, so as to achieve the function of multiple rooms and multiple temperature zones. [0003] The refrigerator controls the temperature of each compartment. By setting the compartment startup temperature and compartment shutdown temperature of the corresp...

AI Technical Summary

Problems solved by technology

In a single-system multi-door air-cooled refrigerator, each room depends on the electric damper to control the cooling capacity, and the cooling demand and time of each room are different, so each damper is easy to switch alternately when the refrigerator is actually cooling, so that the efficiency of the fan is low most of the time. Ineffective state, the compressor runs for a long time, and the power consumption increases
