10、o oad According to the related standard ed out, surface , directly affect the dissipating capacity of the ground. It is t, under the same heating condition and floor of 0.02m2 K/Win granite, is about 0.10m2 K/W wood floor to construction hesame room,the ceramic tile surface n to high of 30% to 60% t

11、o 60; 90% 0.15m2 K/w carpet. Thus, the surface layer material on the great influence of ground heat dissipating capacity. However, many of the design to simple and convenient for building thermal load only based on experience estimation, which is often the building heat load estimate is too high to

12、form a waste of energy, a serious violation of the requirements of building energy-saving design. For the calculation of the thermal load, must undertake building thermal calculation according to energy efficiency standards, to determine the heat transfer coefficient of building envelope, only reach

13、 the specifications in calculation, to continue the heating load calculation. Ground radiation heating compared convection heating, heating the room order tooad of the rigorous calculation is very complicated, the calculation, can be used according to the convection heating heat load calculation, l

To determine the amount ofheat per unit surface area, should check to the average surface temperature. Land temperature istoo high, after a long

28、ncreased comfort.(three) pipelineAnother factor affecting radiant floor heating system using effect is the ground temperature distribution. Is easy to be ignored in the design s. The ground distribution uniformity is mainly affected by the depth of buried pipe, tube spacing of H S size, tube arrange

29、ment etc. Heating pipeline depth is too small and pipe spacing is too metropolitan lead surface temperature distribution is not uniform, the heating pipeline depth average surface temperature will be high, and in order to guarantee the ground distribution, general pipe spacing, or n 300mm, if the tu

30、be spacing of 300mm is dense, water flow by adjusting the heating pipe, water temperature to meet the requirements When peline nd pitch size is determined, layout will affect the uniformity the temperature distribution on the ground. Inside the room, the basedon theuseof thermal heat of theroom, lay

Because of the larger the outer window or wall heat loss, the general will be high pe section in priority arrangement, or in certain range along the window wall is dense, i.e. shrinking spacing. The engineering design of

32、the basic note, but dont tube is too close, the window along the outer side of the ground temperature ishigh, he lossof heat. The local temperature (such as high temperature at the outlet of the heating pipe, and the cloth relatively dense), when there is a requirement for the surface temperature on
