Refrigeration device and condensation prevention control method thereof

Abstract

The invention provides a refrigeration device and a condensation prevention control method thereof. The condensation prevention control method comprises the following steps of acquiring the environment temperature and humidity of the environment where the refrigeration device is located so as to obtain an environment detection value; detecting the temperature at the condensation prevention area ofthe refrigeration device so as to obtain a condensation temperature detection value; judging whether the environment detection value or the condensation temperature detection value is abnormal or not; if not, calculating the dew point temperature according to the environment detection value, opening a heating device arranged at the condensation prevention area until the preset heating shutdown condition is met, and recording the heating state of the heating device when the condensation temperature detection value is smaller than the dew point temperature; if yes, extracting the heating staterecord of the heating device, and controlling the heating device according to the heating state record. The alarm signal can be output under the condition that the environment detection value or the condensation temperature detection value is abnormal, so that the user can know the fault so as to carry out corresponding maintenance.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device and an anti-condensation control method thereof. Background technique [0002] Due to the temperature difference between the inside and outside of the refrigeration unit, condensation will occur at the contact position between the box body and the door body. The existing anti-condensation solutions are generally: according to the relationship between the ambient temperature and humidity of the environment where the refrigeration device is located and the temperature in the anti-condensation area of ​​the refrigeration device, start or close the heating wire or other heating devices to avoid condensation when the temperature is lower than the dew point temperature. dew. [0003] Although this anti-condensation control method solves the problem of insufficient anti-condensation control accuracy to a certain extent, it mainly relies on the environmental...

[0003] Although this anti-condensation control method solves the problem of insufficient anti-condensation control accuracy to a certain extent, it mainly relies on the environmental detection value or the condensation temperature detection value. Once the detection value is abnormal, it will affect the start and stop of the heating device. control, leading to a decline in user experience
