日标方管JIS-G0321公差范围
日标方管：为使机组在低负荷下节能，采用启/停控制方式进行能量调节仍然非常必要。3燃气机热泵供暖的季节能耗及运行费用分析比较若考虑各个温度下空调运行的累积时间，可以计算出燃气机热泵冬季运行时的能耗。根据上海地区空调运行期间室外温度频率表[5]计算的燃气机热泵在冬季各个温度下的运行能耗。可以看出能耗较高的点集中在室外温度为5～1℃的区域，这是因为这个温度区域空调运行小时数很多。将各个温度下的能耗值累加起来，可得到整个供暖季节燃气机热泵的能耗量。

STKR400方矩管：
U型换热管可以放置在钢筋笼的内侧，也可以放置在钢筋笼的外侧，用尼龙扎带将其固定在钢筋笼上，并做好对U型管的保护。垂直管水平连接工艺：将垂直管引出承台在桩口处弯曲垂直管使其从套管中穿过，在承台施工完毕后先进行压力试验再熔焊接入水平总管上，以确保接入总管上的热交换管（D32，HDPE）的完好，无渗漏；待每根总管上的孔全部连接完毕后进行压力试验并观察总管上与各个支管相连处的熔焊焊缝有无渗漏；将供回水分别接至相应的分集水器；回填水平管，用沙子或泥土在管道层面上覆盖15cm厚。
