[0023] Referring to Figure 1 As shown, further, the cold and hot adjusting part comprises a three-way reversing valve 6, the three-way reversing valve 6 is arranged on the branch pipe 301, also when the temperature and humidity of a certain place or multiple places in the room reach the dew point, the controller 5 controls the opening of the three-way reversing valve 6 on the branch pipe 301 in one area or multiple areas, to select the switching of cold water or hot water into the branch pipe 301, to adjust the mixing ratio of cold and hot water to accurately control the temperature of the capillary in each partition, to avoid dew.
