The addition of new electronic devices has required the cooling capacity of new vessels to increase. As liquid chillers and its subsequent piping infrastructure are large, heavy, and expensive, it is a priority for naval designers to optimize this machinery. System level modeling allows for the designer to determine what heat loads each chiller will be responsible for. For complex cooling loops with multiple independent heat loads, the amount of machinery that is required to be cooled at any one time is incredibly variable. With a notional four-zone cooling system for a naval vessel, it is possible to split up the thermal loads of a ship into separate manageable loops. This allows for effective thermal management of all necessary equipment. Analysis shows that the York 200 ton chiller, a common chiller in marine applications, effectively meets the expectations of slow-changing thermal loads. However, it cannot rapidly increase cooling power for high powered pulse loads through normal operation. A time delay of approximately 100 seconds occurs between the time of maximum heat load and maximum condenser heat transfer rate. Combined chiller and heat load simulation has lots of opportunities to enhance the efficiency of naval vessels in the future. 2024-12 Thesis https://hdl.handle.net/2142/127511 Simulation of 200 ton chiller and response to heat loads in naval applications Markuson, Luke Richard 2024-12-11 Miljkovic, Nenad System-level Modeling Mechanical Sci & Engineering Mechanical Engineering University of Illinois at Urbana-Champaign M.S.
