About the Instructor
What is this?
Some examples of thermal energy systems
• A heating and cooling system for a commercial or residential building
• A network of pipes and pumps used to transport fluid to and from
various processes within an industrial facility
• Vapor power cycle used to deliver electrical power
• Vapor compression or absorption refrigeration cycle used for cooling
or heating
[Penoncello, Steven G.]
Basic Design Process
• Implement fundamental concepts expressed in terms of various conservation
laws and balances.
• select components of the system to meet the required system performance
while minimizing cost
• the real performance of various components in the system must be known (from
Manufacturer Spec)
• Building the Mathematical Model of the system.
• solve the equations to find the system’s operating point (old method /new method)
[Penoncello, Steven G.]
Example of Thermal System
Some Components of Thermal Systems
• Pipes
• Pumps
• Heat Exchangers
• Air blowers
• Fans
Why is it important to optimize the design?
• When projects are over budget, redesigning flow rates provides nocompromise opportunities to reduce cost.
• When the budget demands it
• When there is limited space or structural support
• When electrical infrastructure can be downsized
• When limited by existing elements in system expansions
• Keep larger pipes to further reduce connected kW and save more
energy
• Reinvest reduced water weight structural savings in other energy and
reducing building components
• Arrange the system in series counterflow to decrease system energy
consumption (HVAC Chillers)
