摘要(Abstract):

通过对重力循环柜联合金属吊顶辐射板运行进行试验研究,测试重力循环柜的补助制冷性能以及对室内热舒适性的影响。研究结果如下:内置三排毛细管的重力循环柜单独运行时,制冷量能够达到设计工况下的720W;重力循环柜联合辐射吊顶系统运行时,重力循环系统能够起到补助制冷作用,并对出风口周围地板结构有一定的蓄冷作用,具有部分辐射供冷的效果。当室内达到稳定状态后,距重力循环柜水平30cm以内的区域在32min内垂直温差大于3℃,30cm以外区域温度场满足人体舒适性要求。
In order to test gravity tank subsidies cooling performance and the influence of indoor thermal comfort,through the method of experimental research,we make research on the gravity tank about itself refrigeration performance and performance of gravity tank joint metal radiant panel operation.The results as follows: The refrigerating capacity of built-in three rows of capillary core gravity tank can reach the design condition 720W,when hybrid air conditioning system runs,indoor temperature can be maintained,when gravity tank provide subsidies refrigeration,it also has the cold storage function on ground structure.The region which off the gravity cabinet horizontal direction less than 30cm,in a certain period of time the vertical temperature difference greater than 3℃,but 30cm outside the temperature field meet human comfort requirements.
