AI Technical Summary
Technical Problem
In refrigeration equipment, when the internal temperature of the refrigeration equipment is close to the ambient temperature, the compressor does not cool for a long time, resulting in excessive humidity, affecting the storage of internal items and even causing mold.
Method used
By monitoring the operation of the compressor and the humidity in the storage chamber, the coordinated operation of the compressor, fan and heating device is controlled to reduce the humidity and stabilize the temperature to avoid over-cooling.
Benefits of technology
It can reduce the disturbance of the internal temperature of the refrigeration equipment while dehumidifying, keep the humidity and temperature in the storage cavity stable, and prevent the items from getting moldy.

Abstract
The invention provides a dehumidification control method of refrigeration equipment and the refrigeration equipment. The refrigeration equipment comprises a storage cavity and an air duct cavity; the storage cavity is used for storing articles; the air duct cavity comprises a refrigerant system and a fan, and the refrigerant system comprises a compressor, a condenser, a throttling device and an evaporator and is used for providing cooling capacity for the storage cavity; the fan is used for conveying cold air generated at the evaporator into the storage cavity; the refrigeration equipment further comprises a first heating device arranged on the air outlet side of the draught fan. The dehumidification control method comprises the steps that the operation condition of a compressor is obtained; the humidity in the storage cavity is obtained; and if the running condition of the compressor represents that the starting duration of the compressor in the set time interval is smaller than a duration threshold value, and the humidity is larger than or equal to a first humidity threshold value, the compressor, the fan and the first heating device are controlled to start running. When the compressor is controlled to operate to reduce humidity, the air blown into the storage cavity is heated through the first heating device, and dehumidification and temperature stability in the storage cavity are both considered.
