Embodiment 1

[0034] See Figure 1 As shown, the present invention is a refrigeration temperature regulation control system, comprising a selection module, a control module and a request module. The selection module includes a temperature acquisition unit, a judgment unit and a selection unit; The temperature acquisition unit is used to collect the cold room temperature and the freezer temperature and send the collected data to the judgment unit.

[0035]The judgment unit compares the temperature of the collection cold room with the temperature of the freezer chamber and the corresponding preset temperature, determines the temperature range of the cold room temperature and the freezer room temperature, and transmits the judgment result to the selection unit; The selection unit selects the corresponding fan operating speed gear according to the judgment result of the judgment unit.

[0036] The request module is connected to the selection module; After receiving the fan start command, the request...

Embodiment 2

[0063] On the basis of Example 1, the duty cycle of the fan operation, according to the small to large divided into six duty cycle gears, and the duty cycle gear of the fan and the speed gear according to the small to large one correspond. For example, when the fan speed gear is selected in the embodiment is S6, the corresponding fan duty cycle is 100%. The compressor operating rate is adjusted by synchronously controlling the duty cycle and speed of the fan operation.

Abstract

The invention discloses a freezing temperature adjustment control system, which relates to the technical field of refrigerators. The invention includes a selection module, a control module and a request module; the request module transmits the request signal to the selection module after receiving the start command of the fan; the temperature acquisition unit in the selection module collects the temperature of the refrigerating chamber and the temperature of the freezing chamber, and sends them to the judging unit The judging unit compares the temperature of the refrigerating chamber and the freezing chamber with the corresponding preset temperature, and transmits the judgment result to the selection unit; the selection unit selects the corresponding fan speed gear according to the judgment result; The gear position information starts the fan. The invention adopts the temperature combination of the refrigerating room and the freezing room to determine the running speed gear of the fan, realizes reasonable adjustment of the fan speed, and solves the problem of improper adjustment of the air volume in the existing refrigerating room, and the temperature of the freezing room is easy to be too high or too low to affect the freezing and fresh-keeping effect , as well as problems that lead to increased energy consumption.

Description

Technical field [0001] The present invention belongs to the field of refrigerator technology, in particular to a refrigeration temperature regulation control system and a control method thereof. Background [0002] With the development of the domestic home appliance industry, the types of air-cooled refrigerators have increased a lot, of which the economic air-cooled refrigerators have increased year by year in recent years. This type of refrigerator air duct system structure is simple, manual adjustment of refrigerated air volume, to achieve compressor start and stop control, the cost is relatively low, is an economic product, the market sales are more. [0003] The existing refrigerator products of this type can not automatically adjust the refrigerated air volume, but in the refrigerated air duct set up an air volume adjustment lever to manually control the refrigerated air supply volume, while controlling the opening and stopping of the compressor according to the fluctuation...
