对大型商业建筑中单、双蓄热式暖通空调系统（热水和冷冻水）的运行特性、优化运行策略和经济可行性进行了研究。开发了新泽西州Long Branch的Electronic Associates，Inc.（E.A.I.）办公楼暖通空调储热系统的计算机仿真模型，并将其与实际运行数据结合使用，以定义和测试具有储热功能的空间调节系统的最佳模式。该系统各部件的热力学模型被纳入计算机仿真模型中，该模型可轻松编程用于各种HVAC蓄热系统和运行模式。 EAI系统的最佳双水箱模拟（与无存储系统相比）在夏季将峰值电力需求（Kw）降低了36%，在冬季降低了75%。50%的年度高峰（上午10点至晚上10点）能源（Kwh）需求被转移到非高峰时间。所需的总电能（Kwh）仅减少了3%。基于10.10美元/千瓦的高峰需求费用，建筑暖通空调总运营成本降低了39.9%；这使得双罐系统及其相关管道和泵的简单投资回收期预计为4.8年。这些结果表明，蓄热作为减少高峰需求和能源需求以及降低暖通空调运行成本的替代方案具有巨大的潜力。 引文:加利福尼亚州洛杉矶ASHRAE Transactions第86卷第1部分

The operational aspects, optimal operating strategies and economic viability of a single and dual thermal storage HVAC system (hot water and chilled water) in a large commercial structure was studied. A computer simulation model of the HVAC thermal storage system of the Electronic Associates, Inc. (E.A.I.) office buildings in Long Branch, N.J. was developed and used in conjunction with actual operation data to define and test optimal modes of space conditioning systems with thermal storage.Thermodynamic models of each component of the system were incorporated into the computer simulation model, which may be easily programmed for a wide range of HVAC thermal storage systems and modes of operation.An optimal two tank simulation (as opposed to a no storage system) of the EAI system reduced peak electric demand (Kw) by 36% in the summer and 75% in the winter. 50% of the yearly on-peak (10 a.m. to 10 p.m.) energy (Kwh) requirement was shifted to off-peak times. Total electric energy (Kwh) required was reduced by only 3%. The total building HVAC operating costs were reduced by 39.9%, based on an on-peak demand charge of $10.10/Kw; this produces an estimated simple payback of 4.8 yr for the two tank system with its associated piping and pumps. These results indicate a significant potential for thermal storage as an alternative for reducing on-peak demand and energy requirements and decreasing HVAC operating costs.
