1、创制单位:2、应用范围:可以根据建筑物的门、窗、墙、天棚等外形尺寸及各种建筑材料之换热系数、温差及附加系数来计算建筑物的外围耗热量。3、工作效率:一般此人工计算快50倍左右。4、精确程度:最大误差小于4%,平均2%左右。5、制作原理:计算依据为外围耗热计算公式 Q=△t·β·Σa·K。本计算机的演算过程分为两步。第一步先求出上 1, create a unit: 2, the scope of application: according to the building’s doors, windows, walls, ceilings and other external dimensions and a variety of building materials, heat transfer coefficient, temperature difference and additional coefficient to calculate the building’s external heat consumption. 3, work efficiency: Generally this manual calculation is about 50 times faster. 4, the degree of accuracy: the maximum error of less than 4%, an average of about 2%. 5. Production principle: The calculation basis is the formula for calculating the external heat consumption Q=△t·β·Σa·K. The computer’s calculation process is divided into two steps. The first step is to find the first
