Embodiment 1

[0074] Embodiment 1, the humidity control space 101 is set to a high humidity mode.

[0075] The refrigeration device 100 in the embodiment of the present invention is an air-cooled refrigerator. The humidity control space 101 in the air-cooled refrigerator is set to a high humidity mode, and the first predetermined humidity is set to 90%.

[0076] The control methods include:

[0077] Such as image 3 As shown, detect whether the humidity in the humidity control space 101 is greater than 90%; when the humidity in the humidity control space 101 is not greater than 90%, close the damper 21, and retest after a period of time; when the humidity in the humidity control space 101 is greater than 90%, detect Whether the temperature in the humidity control space 101 is greater than 2°C; when it is not greater than 2°C, close the damper 21, and retest after a period of time; when it is greater than 2°C, check whether the evaporator 4 is in the defrosting period; in the defrosting pe...

Embodiment 2

[0078] In the second embodiment, the humidity control space 101 is set to a high humidity mode.

[0079] The refrigeration device 100 in the embodiment of the present invention is a direct cooling refrigerator. The humidity control space 101 in the direct cooling refrigerator is set to a high humidity mode, and the first predetermined humidity is set to 90%.

[0080] The control methods include:

[0081] Such as Figure 4As shown, detect whether the humidity in the humidity control space 101 is greater than 90%; when the humidity in the humidity control space 101 is not greater than 90%, close the damper 21, and retest after a period of time; when the humidity in the humidity control space 101 is greater than 90% , detect whether the temperature in the humidity control space 101 is greater than 2°C; when it is not greater than 2°C, close the damper 21, and retest after a period of time; when it is greater than 2°C, open the drawer damper 21, and retest after a period of time...

Embodiment 3

[0082] Embodiment 3, the humidity control space 101 is set to a low humidity mode.

[0083] The refrigeration device 100 in the embodiment of the present invention is an air-cooled refrigerator. The humidity control space 101 in the air-cooled refrigerator is set to a low humidity mode, and the second predetermined humidity is set to 40%.

[0084] The control methods include:

[0085] Such as Figure 5 As shown, detect whether the humidity in the humidity control space 101 is greater than 40%, when the humidity in the humidity control space 101 is not greater than 40%, close the drawer damper 21, and retest after a period of time; when the humidity in the humidity control space 101 is greater than 40%, Detect whether the temperature in the humidity control space 101 is greater than 2°C. When it is not greater than 2°C, close the drawer damper 21 and retest after a period of time. When it is greater than 2°C, detect whether the evaporator 4 is in the defrosting period During...

Abstract

The invention discloses refrigeration equipment and a control method of the refrigeration equipment. The refrigeration equipment comprises a storage cavity and a moisture adjusting air way, wherein moisture control space is formed in the storage cavity; one end of the moisture adjusting air way communicates with the moisture control space, and the other end communicates with an air return area ina heat exchange cavity of an evaporator of a freezing chamber of the refrigeration equipment; and an air door is arranged on the moisture adjusting air way, and is used for controlling communication between the freezing chamber and the moisture control space. According to the refrigeration equipment, in the process of controlling and adjusting humidity of the moisture control space, the detectionof refrigeration state parameters of the freezing chamber is not needed, and the judgment if the freezing chamber or a refrigeration chamber meets dehumidifying conditions is not needed; the air dooris closed when high humidity is needed, and the air door is opened for dehumidification when low humidity is needed only according to the humidity in the moisture control space and the high-humidity or low-humidity demands of the moisture control space; and the refrigeration equipment is simple in structure and excellent in moisture control effect.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigeration device and a control method for the refrigeration device. Background technique [0002] In the related art, the technical solution for the refrigerator to dehumidify the sealed drawer mainly includes: 1) controlling the humidity in the drawer by adding a freezing air inlet and an air outlet with a water-blocking breathable film on the sealed drawer; 2) sealing the drawer with The refrigerating room has a structure that can adjust the connecting area. By adjusting the sealing degree of the sealed drawer, the air exchange speed between the drawer and the refrigerating room is adjusted, thereby controlling the humidity in the drawer; 3) The sealed drawer and the evaporator have an independent circulation system. During the cooling process of the evaporator, open the circulation channel to realize dehumidification in the drawer; when the evaporator stops ...
