低温热水地板辐射采暖
随着居住条件的不断改善，人们对室内采暖的要求也提出了新的要求。许多工程使用了低温地板辐射采暖系统来代替常见的散热器采暖，克服了诸如耗能大、舒适性差、难于分户计算、占用房间使用面积等问题。由南通六建北京公司施工总承包的未来假日花园二期工程，由A、B、C、D、E楼和地下车库组成，总建筑面积13.7万平方米，其中，B楼建筑面积为21947平方米，C楼建筑面积为21708平方米，均为地下二层，地上十六层，结构形式为钢筋砼剪力墙结构。B、C楼地面采用了低温热水地板辐射采暖系统，共计3.07万平方米。现将施工过程中的一些体会总结出来，以便更好地在其它类似工程中加以应用。

采暖的特点
　　低温热水地板辐射采暖是一种利用建筑物内部地面进行采暖的系统。将塑料管敷设在楼面现浇砼层内，热水温度不超过55℃，工作压力不大于0.4兆帕的地板辐射供暖系统。该系统以整个地面作为散热面，地板在通过对流换热加热周围空气的同时，还与人体、家具及四周的维护结构进行辐射换热，从而使其表面温度提高，其辐射换热量约占总换热量的50%以上，是一种理想的采暖系统，可以有效地解决散热器采暖存在的问题。
　　低温热水地板辐射采暖节省燃料，电力消耗低，是最经济的供暖设备，其优点如下：
　　⑴ 舒适、卫生、保健。辐射散热是最舒适的采暖方式，室内地面温度均匀，室温自下而上逐渐递减，给人以脚暖头凉的良好感觉，符合“温足凉顶
Low temperature hot water radiant floor heating
With the continuous improvement of living conditions, people on the indoor heating requirements also put forward new demands. Many projects use low-temperature radiant floor heating system to replace the common radiator heating, such as the energy to overcome the large, comfortable and poor, difficult to calculate household, occupation of the room floor area and other issues. Nantong six built by the construction general contracting company Beijing Holiday Garden Phase II future, from A, B, C, D, E floor and underground garage, with a total construction area of 137,000 square meters, of which, B floor building area of 21,947 square m, C floor building area of 21,708 square meters, are the basement level, ground 16 floors of reinforced concrete shear wall structure in the form of the structure. B, C using low temperature hot water in floor radiant floor heating system, a total of 30,700 square meters. Some of the construction process will now sum up experience in order to better be in the application of other similar projects.

Heating characteristics
Low temperature hot water radiant floor heating is a ground for the internal use of the building heating system. Plastic pipe laid in situ concrete floor layer, water temperature does not exceed 55 ℃, working pressure of not more than 0.4 MPa radiant floor heating system. The system to the ground surface as the heat, floor heating in the surrounding air by convection, while with the human body, furniture and maintenance of the structure around the radiation heat transfer, making it the surface temperature increases, the radiation heat transfer capacity of the total more than 50% of heat transfer, is an ideal heating system, radiator heating can effectively solve the problem.
Low temperature hot water radiant floor heating to save fuel, low power consumption, is the most economical heating system, its advantages are as follows:
⑴ comfort, health, health care. Thermal radiation is the most comfortable way of heating, indoor surface temperature uniformity, temperature gradually decreasing from bottom to top, gives a warm head and cool feet feel good, meet the "warm feet and cool head
