Air-cooled refrigerator and its control method and control system

Abstract

The invention provides an air cooling refrigerator and a control method and control system thereof. A refrigerator body of the air cooling refrigerator is provided with a refrigerating chamber and a freezing chamber. The freezing chamber is internally provided with an evaporator and a freezing air outlet fan. The refrigerator body is provided with an air feeding flue and an air returning flue. The refrigerating chamber is internally provided with a refrigerating chamber air outlet and a refrigerating chamber air returning port which are communicated with the air feeding flue and the air returning flue respectively. The freezing chamber is internally provided with a freezing chamber air outlet and a freezing chamber air returning port which are communicated with the air feeding flue and the air returning flue respectively. The refrigerating chamber is internally provided with a refrigerating chamber air door capable of opening or closing the refrigerating chamber air outlet. A refrigerating chamber air returning fan is arranged at the refrigerating chamber air returning port. When the refrigerating chamber air returning fan is started, the flow speed of airflow in the air returning flue can be increased. According to the air cooling refrigerator, the refrigerating chamber air returning fan is arranged at the refrigerating chamber air returning port, the flow speed of airflow in the air returning flue is increased, and the phenomenon of icing of water steam in airflow in the freezing chamber air returning port and the phenomenon of condensation at a door groove of the refrigerating chamber are reduced.

Description

technical field

[0001] The present invention relates to the field of refrigeration equipment, and more specifically, to an air-cooled refrigerator, a control method for controlling the air-cooled refrigerator, and a control system for the air-cooled refrigerator. Background technique

[0002] At present, in the air-cooled refrigerators on the market, the cooling of the refrigerated compartment and the variable temperature compartment must be blown out by the freezing fan after the heat exchange of the evaporator, and the air is sent to the refrigerated compartment and the variable temperature compartment, and then passed through the refrigerated compartment. And the return air duct of the variable temperature compartment sends the return air to the return air outlet of the freezing air duct to achieve. Due to the temperature characteristics of the refrigerated compartment and the variable temperature compartment, the temperature of the return air flowing back from the refrig...
