在空调通风系统中,为节省能量、减少热量和冷量的损失,并为了防止在夏季运行中送风管道外表面结露,空调送风管道都采用了保温措施。以某工程的空调送风管道为例,经对美国和国内设计选用的2种厚度的保温材料进行计算、测试、对比,表明2种厚度在使用中虽各有利弊,但都能达到节能保温的目的。 In air-conditioning and ventilation systems, to save energy, reduce heat and cold loss, and to prevent dew condensation on the outer surface of the supply duct during summer operation, air-conditioning supply ducts are insulated. Taking an air-conditioned air supply duct of an engineering project as an example, two kinds of insulation materials selected for design in the United States and in China are calculated, tested and compared, which shows that each of the two thicknesses has advantages and disadvantages in use, the goal of.
