金属反射式保温最早在1800年产生于英国热量计的保温经验,1955年首次正式作买际应用。与重型块状保温不同,反射式保温是通过刚性组件内装置的连续金属层的热反射,挡阻热损失,并供有横断片压制空气的对流。图16表示二种类型保温的工作原理。对重型保温,外表面温度一般不知,必须从导热系数计算热损失。通过金属反射保温的热损失可以不知外表面温度的情况下计算出来。
Metal reflective insulation as early as 1800 produced in the British thermal meter insulation experience, the first official in 1955 for the purchase of the occasion. Unlike heavy block insulation, reflective insulation is the heat reflection through the continuous metal layer of the fixture within the rigid assembly, blocking the heat loss and providing convection of the cross-section compressed air. Figure 16 shows the working principle of two types of insulation. For heavy insulation, the outer surface temperature is generally unknown, heat loss must be calculated from the thermal conductivity. Heat loss through metal reflection can be calculated without knowing the temperature of the outer surface.
