The general situation of natural gas source in china and the economy of wall - mounted gas boiler for individual heating are analyzed , and the current situation analysis and forecast on heating load of gas heating are made 摘要分析了我国天然气的气源概况和燃气壁挂炉分户采暖的经济性，进行了燃气采暖热负荷的现状分析和预测。
Thirdly , at the basis of burners that have been adjusted , the design of the wall in the boiler which has some heat - load has been made and assembled charts has been protracted and the products will be made in factory 再者，在改造过的燃烧器的基础上，进行一定热负荷的锅炉炉体的设计，绘制出锅炉装配图。并在工厂加工成成品。
The results are significant . the change of evaporating temperature and control precision influence the temperature fluctuation of the air , which is relevant to the heat - load matching of warehouse and refrigerating units 温度场的波动主要是两个原因引起的：蒸发温度的波动及控制的精度，也就是气调库的热负荷要与机器的负荷相匹配。
The pertinence of actualizing the measures is particular , which requires the status of remaining heating and cooling load , building utility , meteorological data , etc . should synthetically be taken into consideration 但节能技术措施的实施具有较强的针对性，需要综合无余热负荷（冷负荷） 、建筑功能、气象参数等多方面的因素进行综合考虑。
To reduce the amount of heat load in the thermometer due to electrical leads of heat conduction , to improve the accuracy of measurement temperature , it is very important and virtual means to utilize heat sink 摘要为了减小引线导热在温度计上的热负荷，提高温度测量的精确度，并保证有效地减小温度计的传导热，热沉的利用是经常而必用的手段。
The cooling or heating loads of different conditioned zones in one system are highly diversified and variable , or the time of operation under low load is long , and the temperatures in conditioned zones need to be controlled individually 同一个空气调节风系统中,各空调区的冷?热负荷差异和变化大?低负荷运行时间较长,且需要分别控制各空调区温度
