Specifically, the ring temperature was 38 ℃ and the humidity was 85%, at which point the dew point temperature was 35.03 ℃. The refrigerator starts to operate with preset values ty1 ═ 35.03+1 and ty2 ═ 35.03+2, so that the refrigerant flowing out of the compressor 20 first flows into the condensing device 30 to operate in the refrigeration cycle. It is determined whether the temperature t is less than a preset value ty1, and when the temperature t <35.03+1, the circulation path refrigeration cycle is changed such that the refrigerant flowing out of the compressor 20 first flows into the condensing device 30 to operate. The refrigeration cycle is resumed to operate the refrigerant exiting the compressor 20 by first flowing into the condensing unit 30 until the monitored temperature t >35.03+ 2. The two preset values are different because the monitoring value of the sensor is considered to have a certain error, and meanwhile, the temperature of the dew removing pipe 33 can be ensured to be higher than the dew point temperature and be kept for a period of time so as to prevent condensation.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
