Design a small, laboratory-scale, reversed Brayton cycle air conditioning system that can serve as an experimental apparatus for a junior or senior mechanical engineering laboratory course. The system must be instrumented with the proper pressure, temperature, and mass flow transducers so that its coefficient of performance can be accurately determined.
The system should have at least one variable parameter to provide a range of performance to study. You may wish to start by modifying an automotive turbocharger to provide the turbine and compressor stages.
Either construct the apparatus yourself or else provide sufficiently accurate and detailed drawings and instructions that it can be made by an engineering technician.
