分户供暖热负荷计算方法初探

采用分户供暖后，供暖热负荷的计算不但要计算户间传热，还必须考虑户内邻室传热的构成和发生概率。由于存在相邻房间供暖不同步因素，指出分户供暖系统设计时应计入户内邻室传热，邻室温差应根据与计算对象相邻房间的用热特点和围护结构组成进行估算，经过大量的调查研究，确定出相邻房间同期系数的经验取值，并提出了各级热负荷的计算方法。

Heating Load Calculation After Implementing Heat Metering

When implementing household-based heating system, the method of heat load calculation should not only consist of household heat transfer, but also the composure and their probability of indoor adjacent heat transfers. Because of the asynchrony of heating between in-door adjacent rooms, indoor adjacent heat transfer should be considered in the design of household-based heating system, and the adjacent temperature difference should be calculated according to the heating characteristic and building envelop of adjacent room. According to a great number of investigations, approximate data of percentage of concurrence between adjacent rooms were obtained and the method of heat load calculation was provided for every level of heat system.
