Abstract

The invention discloses refrigeration equipment and a humidity adjusting method thereof, wherein the refrigeration equipment comprises the steps of continuously monitoring the humidity of a fresh-keeping compartment, judging whether the temperature of the fresh-keeping compartment is lower than a fresh-keeping temperature threshold value when the humidity of the fresh-keeping compartment is higher than a first humidity threshold value, and if so, switching a cooling assembly into a first running state after the refrigeration system is stopped and a preset time passes. Therefore, the temperature in the fresh-keeping room is low and cannot excessively drop, food is effectively prevented from being frozen due to the fact that the temperature is too low, the negative influence of the too low temperature on the food is avoided, the proper humidity environment in the fresh-keeping room is maintained, and the storage quality and the fresh-keeping period of the food are improved.

Description

Refrigerating equipment and humidity adjusting method thereof Technical Field The present invention relates to a refrigeration apparatus, and more particularly, to a humidity adjustment method for a refrigeration apparatus. Background The existing refrigeration equipment generally adopts a single temperature regulation mode, and the storage space is directly cooled through a refrigeration system so as to meet the fresh-keeping requirement of food materials. Some fruits and vegetables can better keep freshness in a high-humidity environment, and the high-humidity environment can avoid the phenomenon that food materials are dehydrated and shrunken due to the loss of moisture, so that the demand of refrigeration equipment capable of providing the high-humidity environment is gradually increased in the market. However, there may be some problems between humidity conditioning and refrigeration of the fresh compartment. On the one hand, the fresh-keeping compartment needs to be relatively separated from other environments in the refrigeration equipment to form a relatively sealed space to realize relatively high humidity, but the humidity in the fresh-keeping compartment is not too high, otherwise, the problems of condensation and frosting can occur. On the other hand, once the humidity adjustment and the temperature adjustment of the fresh-keeping compartment are not well coordinated, the problem that the temperature in the fresh-keeping compartment is too high or too low during the humidity adjustment can occur, the fresh-keeping effect of the fresh-keeping compartment is affected if the temperature is light, and the food materials are frozen or deteriorated if the temperature is heavy. Therefore, how to control the proper humidity of the fresh food compartment, and how to coordinate the humidity and temperature adjustments, all of which, if not solved, would affect the user's use experience.
