The invention provides a refrigeration and freezing apparatus, an anti-condensation method thereof, and an anti-condensation system. The anti-condensation method includes establishing network connection with a remote server; acquiring the temperature and humidity of the external environment of the refrigeration and freezing apparatus from the remote server; acquiring the dew point temperature of the external environment of the refrigeration and freezing apparatus based on the temperature and humidity of the external environment of the refrigeration and freezing apparatus; acquiring the temperature of the outer surfaces of heat insulation parts based on the temperature of the external environment of the refrigeration and freezing apparatus, the temperature inside the refrigeration and freezing apparatus, and the heat insulation coefficients of the heat insulation parts of the refrigeration and freezing apparatus; determining whether the heat insulation parts have the risks of condensation based on the dew point temperature and the temperature of the outer surfaces of the heat insulation parts; and performing the anti-condensation when the condensation risks of the heat insulation parts are determined. According to the anti-condensation method, the temperature and humidity of the external environment of the refrigeration and freezing apparatus can be acquired from a user terminal or the remote server, so that there is no need for the refrigeration and freezing apparatus to be additionally provided with a humiture sensor for detecting environment humiture.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerating and freezing device, an anti-condensation method and an anti-condensation system. Background technique [0002] Condensation is a phenomenon in which a high-temperature, high-humidity gas liquefies into a liquid on the surface of a low-temperature object when it reaches the dew point temperature when it encounters a low-temperature object. Since the temperature inside the box is much lower than the temperature outside the box when refrigerating and freezing equipment such as refrigerators and freezers are in operation, the heat insulation components such as the sides of the box door, the upper beam, the middle beam, and the door seal are directly affected by the box. The effect of cold air inside the body is prone to condensation on its surface. In order to prevent condensation, heating devices are generally attached to the inner surfaces of these heat insu...
