Mechanical single system refrigerator

Abstract

The invention provides a mechanical single system refrigerator. The mechanical single system refrigerator comprises a refrigerator body and a condensation prevention control system arranged on the refrigerator body. The mechanical single system refrigerator is further provided with multiple condensation prevention portions. The condensation prevention control system comprises a temperature control switch set arranged on the refrigerator body; the temperature control switch set comprises a first temperature control switch which is arranged on the refrigerator body and used for sensing the environment temperature and a second temperature control switch which is arranged on at least one condensation prevention portion and used for sensing the temperature of the condensation prevention portions, at least one condensation prevention portion is provided with a heating wire, and the first temperature control switch and the second temperature control switch jointly control the on-off of the heating wires to achieve the temperature control over the heating wires, and therefore the energy consumption is greatly reduced while the condensation removing effect is achieved.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a mechanical single-system refrigerator. Background technique [0002] For traditional mechanical four-door refrigerators, the vertical beams of the refrigerated doors will have condensation problems under high temperature and high humidity conditions. Therefore, it is often necessary to increase the heating wire control to remove dew. Mechanical refrigerators do not have computer board control, so the opening of the vertical beam heating wires The stop control depends entirely on the start and stop of the compressor. In order to ensure the dew removal effect under different ambient temperatures, on the one hand, it is necessary to increase the power of the heating wire to prevent condensation caused by the short start-up time of the press. On the other hand, when the press is started for a long time , The heating time of the heating wire is often relatively long. At this time, the t...

[0002] For traditional mechanical four-door refrigerators, the vertical beams of the refrigerated doors will have condensation problems under high temperature and high humidity conditions. Therefore, it is often necessary to increase the heating wire control to remove dew. Mechanical refrigerators do not have computer board control, so the opening of the vertical beam heating wires The stop control depends entirely on the start and stop of the compressor. In order to ensure the dew removal effect under different ambient temperatures, on the one hand, it is necessary to increase the power of the heating wire to prevent condensation caused by the short start-up time of the press. On the other hand, when the press is started for a long time , the heating time of the heating wire is often relatively long. At this time, the temperature of the vertical beam has already exceeded the dew point temperature or even becomes hot, which will easily lead to redundant heating, which will inevitably lead to excessive energy consumption of the refrigerator.
