摘要：
凡内径很细的管子叫“毛细管”。通常指的是内径等于或小于1毫米的细管，因管径有的细如毛发故称毛细管。目前可以在医学上，建筑材料上都能看得到。
如今，现代建筑的空调系统必须要符合很高的要求。传统的空调系统如通风设备和静态供热很难同时达到最佳热的舒适性、最省的空间和节能的要求 毛细管是这个领域的一项新技术，它可以根据周围环境自动调整。用水做热媒的毛细管使用的是弹性塑料，直接铺在房间围护结构表面的下方。这样房间的天花板、地板和墙壁就会变得非常的温暖舒适。这样，使用者和房间表面之间的能量传递就通过辐射的方式进行。辐射是在自然条件下调整各物体间的热平衡。 研究已经证明，因为这个原因，毛细管网制冷、采暖系统可使人们感觉更舒适，从而具有更高的工作效率。
采用4.3X0.8 mm 的PPR塑料毛细管组成的间隔为10 mm – 30 mm 的网栅，犹如人体中的毛细管，起到着分配、输送和搜集液体的功能。在网栅中和人体毛细管中的液体流动速度基本相同，都在0.05 – 0.2 m/s之间。同时人体皮下组织的毛细血管与周围环境成功地进行了传热交换，达到自身温度调节的目的。
冬季毛细管内通较低温度的热水,柔和的向房间辐射热量；夏季毛细管内通温度较高的冷水,柔和的向房间辐射冷量。由于毛细管席换热面积大，传热速度快，因此传热效率更高。
Abstract：
Where a narrow capillary tubes called "". Usually refers to the inner diameter is equal to or less than 1 mm diametertube, due to some as thin as hair so that capillary. At present, in medicine, building materials, can see.
Nowadays, air conditioning system of modern architecture should meet very high demand. As the air conditioning and ventilation equipment and static conventional heating system is difficult to comfort, space and energy requirements ofthe province of capillary and best heat is a new technique in the field, it can be adjusted automatically according tothe surrounding environment. Capillary do heat medium water is directly below the elastic plastic, shop in theenvelope of a room surface. This room's ceiling, floor and walls will become very warm and comfortable. So, between the user and the energy transfer on the room surfaces by means of radiation. Radiation is the adjustment of the thermal balance between objects in natural conditions. Research has shown that, for this reason, the capillaryrefrigeration, heating system can make people feel more comfortable, so it has higher working efficiency.
Using PPR plastic capillary 4.3X0.8 mm composed of interval for the grid of 10 mm - 30 mm, like capillary in the human body, to the distribution, transport and collect the function of liquid. The liquid in the grid and human in capillary flow velocity is basically the same, are between 0.05 - 0.2 m/s. At the same time the human subcutaneous tissue of the capillary and the surrounding environment successfully carried out the heat exchange, to achieve itspurpose of temperature adjustment.
Low temperature hot water through the winter in a capillary, soft and radiant heat to the room; cold water through high temperature in summer in a capillary, soft radiation cooling to the room. Due to the capillary mat large heat exchange area, fast heat transfer speed, so the heat transfer efficiency is higher.
