本文描述了在明尼阿波利斯一家66562ft餐桌服务餐厅中应用能源管理（包括电力需求限制控制）的研究，该餐厅包含30吨屋顶空调、74 kW电动洗碗机和天然气空间供暖。制定了在屋顶空调机组、制冷设备、通风设备和洗碗机电动辅助加热器上应用需求限制和时间控制的策略。这项研究是在一年的时间内进行的，采用一周开/周关的测试程序，其中能量管理控制装置交替运行一周，然后手动断开。接下来的一周。选择这种测试方法是为了减少业务运营程序的变化、连接负载的变化、电气和气候不规则的影响，这些影响往往会扭曲基于一年的结果- 今年的比较。安装了大量仪表，以监测受控负荷的运行、对空间温度的影响、超控操作和对临界负荷的限制控制、峰值电力需求和总能耗。研究表明，电力需求费用降低了19.7%，电能使用费用降低了8.7%。每年节省的总成本为2440美元，这意味着总能源账单节省了13%，系统安装成本为5083美元，投资回报率为48%。单位:I-PCITION:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

This paper describes a study of the application of energy management including electric demand limit control in a 66562ft table service restaurant located in Minneapolis, which contained 30 tons of rooftop air conditioning, a 74 kW electric dishwasher, and natural gas space heating. Strategies were developed for applying demand-limit and time-of-day controls on rooftop air-conditioning units, refrigeration equipment, ventilation equipment, and a dishwasher electric booster heater.This study was conducted over a one-year period using a week-on/week-off test proceedure in which the energy management controls were in operation alternately for one week and then manually disconnected.for the following week. This testing method was chosen to reduce the effects of changes in the business operating proceedures, changes in the connected loads, electrical and irregularities in the climate that tend to distort results based on a year-to-year comparison. Extensive instrumentation was installed to monitor the operation o£ controlled loads, the impact on the space temperature, the operation of overrides and limit controls on critical loads, peak electric demand, and total energy consumption.The study demonstrated that electric demand charges were reduced 19.7% and that electric energy usage charges were reduced 8.7%. The total annual savings was $2440 which represented a 13% savings on the total energy bill and a 48% return-on-investment on a system installed cost of $ 5083.Units: I-P
