Control method of refrigerating and freezing device

Abstract

Disclosed is a control method of a refrigeration and freezing device (1). The refrigeration and freezing device (1) comprises a cabinet (10) and a compressor compartment (100) provided on the rear of the cabinet (10) and at a lower part thereof, wherein a bottom condenser (103), a cooling fan (102), a compressor (101) and an air blower (104) are sequentially provided in the compressor chamber (100); and the cooling fan (102) is configured to propel air to flow from the bottom condenser (103) to the air blower (104). The control method comprises: acquiring the temperature of the bottom condenser (103) and the ambient temperature; when the temperature of the bottom condenser (103) is greater than the ambient temperature and the difference therebetween is greater than a pre-set first difference value, activating the air blower (104) to forcibly dissipate heat from the compressor compartment (100); and controlling the air blower (104) to stop when the temperature of the bottom condenser (103) drops until the difference between the temperature of the bottom condenser and the ambient temperature is less than a pre-set second difference value. According to the control method, when the bottom condenser (103) of the refrigeration and freezing device (1) cannot perform effective heat dissipation, the air blower (104) is activated to carry out active forced heat dissipation, thereby effectively accelerating the high-temperature air in flowing out of the compressor compartment (100) and preventing the compressor (101) or the bottom condenser (103) from malfunctioning due to an excessively high temperature.

Description

Technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to a control method of a refrigerating and freezing device. Background technique [0002] Refrigeration and freezing devices generally have a certain volume. When a household refrigerating and freezing device, such as a refrigerator, is placed in a restaurant, a kitchen, etc., it protrudes from the wall, which is not conducive to saving space and beautifying the appearance. At present, in order to make the indoor environment beautiful and save space, the built-in refrigerator is usually installed in the cabinet or wall as a component of the kitchen or restaurant, which is convenient to use and optimizes the indoor space. However, the airflow in the cabinet or wall is easily blocked and heat dissipation Difficult ventilation of the system reduces the ventilation and heat dissipation effect of the refrigerator, and cannot meet the performance of the built-in refrig...

Problems solved by technology

When household refrigerating and freezing devices, such as refrigerators, are placed in restaurants, kitchens, etc., they will protrude from the wall, which is not conducive to saving space and beautifying the appearance

At present, in order to make the indoor environment beautiful and save space, the built-in refrigerator is usually installed in the cabinet or wall as a part of the kitchen or dining room, which is convenient to use and optimizes the indoor space. The ventilation of the system is difficult, which reduces the effect of ventilation and heat dissipation of the refrigerator, and cannot meet the performance of the built-in refrigerator
