Problems solved by technology

However, this control method still has certain limitations. When the temperature of the refrigerating room does not reach the set temperature, the refrigerating fan works normally, so that the humidity in the refrigerating room is still kept at a low level, and it cannot be flexibly controlled according to specific needs.

Embodiment Construction

[0035] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] In the air-cooled defrosting refrigerator of the present invention, refrigerating evaporators and freezing evaporators are respectively arranged in the refrigerating chamber and freezing chamber, and the refrigerating fans and freezing fans are used to form respective air duct systems, thereby realizing independent air cooling control of each compartment. In the refrigerating room, the working state of the refrigerating fan is reasonably adjusted according to the temperature of the refrigerating room and the temperature of the refrigerating evaporator, so that the air in the refrigerating room is continuously circulated under the action of the refrigerating fan, and the water vapor on the surface of the evaporator is brought into the refrigerating room, thereby ensuring The refrigerator maintains high humidity.

Abstract

The invention discloses an air cooling refrigerator as well as moisture-preservation control method and system thereof. A chilling chamber is internally provided with a chilling evaporator and a chilling fan. The method comprises the steps of: step A, detecting the temperature TL in the chilling chamber; and step B, judging the magnitude of the TL, if the TL is within a first temperature range, adjusting the rotation speed of the chilling fan to be r1, returning to the step A and continuing detection. The invention can be used for carrying out reasonable and flexible moisture-preservation control on the chilling chamber of the air cooling refrigerator, increases the moisture of the chilling chamber, obviously improves the refreshment property of the chilling chamber, and reduces the energy consumption.

Description

technical field [0001] The invention relates to a moisture control method and system for an air-cooled refrigerator and an air-cooled refrigerator. Background technique [0002] Most air-cooled frost-free refrigerators adopt a single-system refrigeration method, that is, only one evaporator and fan placed in the freezer compartment are used to provide cold air for the freezer 120887OA and the freezer compartment, and the cold air enters the freezer compartment by controlling the opening and closing of the damper. This kind of refrigeration control system is relatively simple, and the technology is relatively mature. However, since there is only one evaporator, almost all the moisture in the refrigerator is brought back to the evaporator in the freezer by means of air circulation to form frost, and is heated by the hot wire regularly. Frost treatment discharges water from the outside of the box, resulting in low humidity in the refrigerator, and the stored food (especially ve...
