供回水温差 meaning in English

temperature difference between su ly and return water
temperature difference between supply and return water

Presents the on - off control mode of refrigerating machine by supply and return water temperature difference and load proportion with an example
摘要以具体的工程实例介绍了利用供回水温差和机组负荷百分数进行机组台数启停控研究制的方法。
A general air - conditioning system is calculated , which indicates that the temperature difference must be less than 12 . 8 and 9 . 2 and 10 respectively in cool air distribution system , chilled water system and cooling water system
计算表明，对于常规空调设计参数，大温差送风的送风温差不宜超过12 . 8 ；大温差冷冻水的供回水温差不宜超过9 . 2 ；冷却水大温差技术在冷却水供回水温差小于10时总是适用的。
To make the thermal efficiency best , y , a , av / as should be : r : [ 60 - 75 ] a : [ 1 - 1 . 5 ] av / as : [ 0 . 8 - 1 ] in this paper , numerical model of solar radiant floor heating system is also built . the model of numerical model is solved by finite differance method . the smaller the distance to the tube is , the higher the temperature on the surface of the floor is
地板表面相邻两管间水平方向的温度分布：距离加热管越近，温度越高；两管中间处温度最低；供回水温差越小，地板表面温度分布越平缓；在供回水温度和排管间距均一定的情况下，地板覆盖层厚度越大，其温度分布越为平缓，对应的地板表面温度分布越均匀。
