Mathematical modelling of air cycle systems for combined heating and cooling.

Summary

Air cycle systems produce significant quantities of relatively high grade heat, allowing them to be employed in combined cooking and cooling of suitable food products. A recent study assembled an experimental air cycle apparatus from readily available components from the aircraft air-conditioning and food industries. Its design was assisted by development of a mathematical model based on performance characteristics of the main components. It was apparent from the model that the available bootstrap was not capable of balanced operation at the extremes of high and low temperatures required. The model was used to identify and assess modifications to balance the flow. The experimental apparatus was built based on the best option, and test results used to validate the model. The model was then extended in a further study to assess the improvements to system performance likely to result from use of a purpose-built bootstrap and other optimised components (termed ‘ideal’ components).
