考虑了基于地热的区域供暖系统的推荐热能存储容量。使用几种不同的方法估计存储量。首先，根据每个地区最糟糕的天气事件评估最大容量。研究了热需求与环境温度的两种不同关系，一种是线性关系，另一种是非线性关系，在较低温度下热负荷较低。对于线性情况，最大推荐存储容量出现在系统负载比（系统设计热负载；资源生产率）为1.25时，而非线性情况显示，负载比约为1.6时，存储容量峰值。由于仅使用一次最坏天气事件忽略了事件间隔的重要性，并且可能过于保守，因此在20分钟内模拟了储罐的运行- 年份期间和重新评估的存储容量。从经济角度对存储容量进行最终评估，以找到成本最低的峰值系统的规模。各城市在存储容量要求方面的巨大差异变得明显。与寒冷的内陆气候相比，位于海洋气候城市的区域供暖系统更适合使用储罐。经济分析模型的结果表明，海上城市在存储容量接近之前预测的最大存储容量时，具有最小的峰值系统成本，而两个较冷的内陆城市的结果表明，不包括储罐。单位:双引文:研讨会，ASHRAE交易，1987年，第卷。 93磅。田纳西州纳什维尔2号

The recommended thermal energy storage capacity for geothermal-based district heating systems is considered. Storage is estimated using several different methods. First, the maximum capacity is evaluated based on the worst case weather event at each locality. Two different relationships for heating demand versus ambient temperature are investigated, one linear and the other nonlinear which has lower heating loads at colder temperatures. For the linear case, maximum recommended storage capacities occurred at a system load ratio (system design heating load; resource production rate) of 1.25, while the nonlinear case showed peak storage sizes for a load ratio of approximately 1.6.Since the use of only a single worst case weather event ignores the significance of event spacing and may be overly conservative, the operation of the storage tank was simulated over a 20-year period and the storage capacity reevaluated. A final evaluation of storage capacity was done from an economic perspective to find the size that gives the lowest cost peaking system. A strong disparity in storage size requirements among the cities became apparent. District heating systems located in cities characterized by maritime climate were found to be better suited for the use of storage tanks than colder inland climates. The results of the economic analysis model indicate that the maritime cities have a minimum peaking system cost at storage size close to the maximum storage capacities previously predicted, while the results for the two colder inland cities suggest that no storage tanks be included there.Units: Dual
