Refrigeration equipment and its defrosting control method

Abstract

The invention discloses a refrigeration device and a defrosting control method thereof. The method includes the steps: detecting cumulative refrigeration operation time and door opening frequency of the refrigeration device; starting the defrosting process if the cumulative refrigeration operation time reaches first preset time and the door opening frequency reaches preset door opening frequency; determining defrosting quit temperature according to the cumulative refrigeration operation time and the door opening frequency in the defrosting process; quitting the defrosting process when the temperature of a defrosting sensor reaches the defrosting quit temperature. According to the defrosting control method of the refrigeration device, defrosting is controlled according to the frosting condition in the refrigeration device, the refrigeration device cannot frequently perform defrosting, energy consumption is reduced, and the defrosting process can be timely and rapidly started when the refrigeration device is high in usage frequency and large in frosting quantity.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a defrosting control method for a refrigeration device and a refrigeration device with the defrosting control method. Background technique [0002] The defrosting control method of the traditional refrigeration equipment is as follows: the cumulative cooling operation time reaches the predetermined time, enters the defrosting preparation, reduces the cooling control shutdown temperature, that is, pre-cooling is used to balance the temperature rise during defrosting, and turns on the heater when the cooling stops. For defrosting, when the defrosting sensor temperature reaches the predetermined defrosting exit temperature, disconnect the heater and exit defrosting. [0003] However, the frosting method of traditional refrigeration equipment does not combine the conditions of use, and adopts a unified and fixed method. When the frequency of use is small and the amount of frosting is s...

Problems solved by technology

[0003] However, the frosting method of traditional refrigeration equipment does not combine the conditions of use, and adopts a unified and fixed method. When the frequency of use is small and the amount of frosting is small, defrosting is still more frequent, resulting in waste of energy; Under the condition of a large amount of frosting, the original fixed time is still used to defrost, resulting in untimely defrosting and poor heat exchange effect of the evaporator, which directly affects the storage temperature of food and increases energy consumption.

In addition, pre-refrigeration before defrosting, because the temperature control is lower than normal storage, resulting in increased energy consumption
