Control method for cold storage and refrigeration device

Abstract

The invention provides a control method for a cold storage and refrigeration device. The cold storage and refrigeration device comprises a box body and a compressor cabin arranged below the rear partof the box body, wherein the compressor cabin is internally provided with a bottom condenser, a cooling draught fan, a compressor and an air blower in sequence; the cooling draught fan is configured to accelerate air to flow to the air blower from the bottom condenser; the control method comprises the following steps: acquiring temperature of the bottom condenser and environment temperature; whenthe temperature of the bottom condenser is greater than the environment temperature and exceeds first difference, starting the air blower to carry out forced heat dissipation on the compressor cabin;and when the temperature of the bottom condenser is reduced and the difference between the temperature of the bottom condenser and the environment temperature is less than pre-set second difference, controlling the air blower to be stopped. According to the control method provided by the invention, when effective heat dissipation of the bottom condenser of the cold storage and refrigeration devicecannot be realized, the air blower is started to carry out initiative forced heat dissipation, so that the high-temperature air is effectively prompted to flow out of the compressor cabin in an acceleration manner, and faults caused by the fact that the temperature of the compressor or the condenser is too high are avoided.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a control method for a refrigerating and freezing device. Background technique [0002] Refrigerating and freezing devices generally have a certain volume. 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, built-in refrigerators are usually installed in cabinets or walls as part of kitchens or restaurants, which are convenient to use and optimize 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 embedded refrigerator. Contents of the invention [0003] An object of the present invention i...
