Packaged Gas Fired Cogeneration Systems Development for Fast Food Restaurants

摘要

A large number of applications exist in fast food restaurants (5000+ for McDonald's alone) that could benefit from gas fired cogeneration systems. Typically, these applications have long operating hours with relatively constant electrical usage. Although design heating and cooling loads vary appreciably with geographical location, all stores have appreciable HVAC loads to support kitchen exhaust. The final report details the data gathering effort on 1,000 McDonald stores, a 28 city building load simulation, the component selection, system design, and economic analysis. The selected system design was based on McDonald's standard 39 x 89 store and utilizes a 70 kW turbocharged Waukesha engine, 30-ton Hitachi chiller-heater, and a gas fired power burner for supplemental or backup heating and cooling.
