摘要:
通过实验测试,研究冷辐射板表面快结露时,冷冻水阀门调节模式对冷辐射板的防结露效果、制冷能力和室内热舒适性的影响.结果表明:在冷辐射板表面快要结露时,冷冻水阀门通断调节模式下有较好的防结霜效果,但辐射板制冷能力会下降,室内热舒适性变差;冷冻水阀门比例积分微分(PID)调节模式下的供水流速为0.30~0.45 m·s-1时,冷辐射板既有较好的防结霜效果和制冷能力,又能维持较好的室内热舒适性.
Abstract:
By means of experimental test, the influence of regulation mode of the cooling water valve on the anti-condensation performance, refrigeration capacity and indoor thermal comfort of the cold radiant panel was investigated, when the surface of the cold radiant panel is about to condense. The results show that the best anti-condensation effect of the cooling water valve in the on-off regulating mode is benign, however, the cooling capacity of the radiator plate decreases, and the indoor thermal comfort degrades. When the flow rate of the cooling water valve in the proportion integration differentiation(PID)regulating mode is 0.30-0.45 m·s-1, the cold radiation plate has better anti-condensation performance and refrigeration ability, and can maintain better indoor thermal comfort.
