Problems solved by technology
Condensation not only affects the normal heat exchange work of the air conditioner, but also easily breeds bacteria near the condensation position. In severe cases, water droplets may appear, which will affect the normal work of indoor personnel.
The radiant cooling air-conditioning system is prone to condensation, which makes the surface temperature of the radiant cooling air-conditioning system board higher, which limits the cooling capacity of the entire system
In areas prone to condensation such as high air humidity, the radiant cooling air-conditioning system cannot be applied due to the limitation of the processing capacity of the fresh air unit.

Embodiment Construction
[0044] The following is a further description of the present invention.
[0045] 1) if figure 1 As shown in the drawing, when the number of people in the room increases by 5, the water supply flow rate will be reduced by 0.36m 3 / h when the plate surface temperature change curve and the dew point temperature change curve, but again, when the number of people increases, reducing the water supply flow at the same time can not maximize the cooling capacity; by figure 1 It can be seen that the best adjustment time to reduce the water supply flow rate should be a period of time after the increase of personnel. Since the difference between the initial plate temperature and the initial air dew point temperature of the attached layer is large, when the air dew point temperature of the attached layer increases to close to When the surface temperature of the radiant panel is reduced, the rate of increase of the surface temperature of the radiant panel after the water supply flow is red...

The invention discloses a method for determining the best anti-condensation safety temperature difference of a radiant air conditioner by adjusting the water flow. According to the method, the surfacetemperature change of a radiant cooling system and the air dew point temperature change of an adhesion layer are coupled, it is ensured that the cooling capacity of a radiant plate is sufficiently achieved on the non-condensation premise, and a best safety temperature difference prediction model of a radiant air conditioner water flow adjusting system is given as shown in the specification.
Description
technical field [0001] The invention relates to the field of radiant cooling, and relates to a method for adjusting the flow rate of water supply to determine the best safe temperature difference for anti-condensation of a radiant air conditioner. Background technique [0002] Radiation cooling refers to the technology of reducing the temperature of one or more inner surfaces in the enclosure structure to form a cold radiation surface, and relying on the radiation heat exchange between it and the surface of the human body, furniture and other enclosure structures to cool down. Radiant cooling air-conditioning systems have many advantages that traditional air-conditioning systems cannot match, especially in terms of energy saving and thermal comfort. Compared with traditional air-conditioning forms, radiant cooling air-conditioning systems use low-grade cold sources and have better energy-saving performance. , It also has great advantages in improving indoor air quality and e...
