With the continuous improvement of living standard and the continuous progress of science and technology of people, the requirement of users on indoor environment is higher and higher; the traditional forced convection heat exchange air conditioner changes the indoor temperature and humidity by adopting a mode of indoor air internal circulation convection heat transfer, and the mode easily causes discomfort of indoor users. And in the end of the 20 th century, 80 s, the capillary network planar radiation system was attracted extensive attention by the german DonadHerbst utility model. Such invisible air conditioning systems have since been used in many high-end commercial buildings, banks, utilities and medical constructions for decades. The capillary network radiation temperature control technology is combined with the fresh air technology, the capillary network provides sensible heat, and the fresh air processing unit provides latent heat and fresh air required by air exchange; compared with the traditional air conditioning mode, the air conditioning system has the remarkable advantages of stable and safe operation, no blowing feeling, low noise, comfort, energy conservation, uniform indoor temperature and the like.

But the prior capillary network radiation fresh air conditioning system also has some defects; in the use process, when the surface temperature of the indoor capillary network is lower than the dew point of indoor air, condensation is easy to occur, and the wall surface is moldy due to the poor treatment of the condensation problem. At present, a method of closing a water path is commonly adopted in a radiation air conditioning system, and although the condensation phenomenon can be prevented from increasing in a short time, the condensation phenomenon still easily exists. In addition, especially in the transition season, the outdoor humidity load is large, but the temperature is reduced, so that heating is needed while dehumidification is needed indoors, and the normal system operation mode can cause indoor supercooling and large energy consumption; the existing fresh air system also depends on the working of the outdoor unit in the dehumidification process, and a large amount of electric energy is consumed in the mode.

According to the dehumidifier, the central controller controls the dehumidifier to start dehumidification, and meanwhile, the water outlet temperature of the heat pump is increased to avoid condensation; however, in the case of sudden window opening, after the water temperature is changed by the heat pump, the rising rate of the water temperature is slow, and electric energy is consumed, so that more effective dewing prevention is difficult to achieve.
