AE 6590 - District Energy Mechanical Systems3 lecture hours 0 lab hours 3 credits
Course Description
This course evaluates district energy as a part of integrated systems that provide one or more forms of thermal energy or a combination of thermal energy and electric power from a central plant(s) to meet the heating, cooling, or combined thermal energy and power needs of end-users. The course will cover the design, performance, operation and maintenance, transmission and distribution networks, heat transfer, fluid flow, and measurement of thermal energy from district energy systems in addition to covering the environmental impacts compared to on site generation at each facility. This course will also stress the coordination and integration with electric district energy system components typically housed within on the same site. (prereq: graduate standing)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Identify the required components in a district energy system
- Calculate how to size equipment to meet full-load and part-load conditions
- Discuss various heating and cooling equipment options for central plants
- Calculate the load for a district energy system including system diversity
- Identify buildings that are candidates for inclusion in the district energy system
- Discuss the types of piping and joining methods used in district systems
- Discuss the site distribution options for cooling and heating systems
- Create site distribution profiles based on existing topography
- Discuss the various methods of flow rate measurement at the consumer interconnection
- Explain the basic components required of a steam and condensate system
- Design a basic steam system including pipe sizing, steam traps, drip legs, pressure reducing valves, condensate pumps, and boiler feed pumps
- Design a district energy system with team members for an integrated design
