5.问:各部分围护结构传热系数限值是怎样规定的? 答:原标准对满足第一阶段耗热量指标要求的围护结构平均传热系数限值,以及这一限值随体形系数和朝向进行修正的方法作出了规定,但在实际执行时这方面的规定一般都不采用。这是因为原标准第三章规定了耗热量指标的计算方法,据此已能求得各部分围护结构的传热系数。此外,从原标准附录中也能查得各部分围护结构传热系数的建议值,有关围护结构平均传热系数的规定已显得重
5. Q: What is the limit for the heat transfer coefficient of each part of the enclosure structure? A: The original standard specifies the average heat transfer coefficient of the enclosure structure that meets the requirements of the first stage heat dissipation index, and this limit is related to the body shape. The method for adjusting the coefficient and orientation has been stipulated, but in practice, the provisions in this area are generally not adopted. This is because the third chapter of the original standard stipulates the calculation method of the calorie consumption index. Based on this, the heat transfer coefficient of each part of the envelope structure can be obtained. In addition, the recommended values for the heat transfer coefficient of the enclosure structure can also be found in the appendix of the original standard. The provisions for the average heat transfer coefficient of the enclosure structure are already heavy.
