This application analyzes a vapor compression refrigeration cycle for the refrigerant R134a. The application calculates heat changes  over the compressor, condenser, throttle and evaporator, together with the coefficient of performance. Additionally, a P-h-T chart illustrating the refrigeration cycle is plotted.

Thermophysical properties are provided by the open source C++ CoolProp library (http://coolprop.org). Once compiled and linked to Maple, CoolProp lets you access the properties of pure fluids, pseudo-pure fluids, and humid air with a function call. This application comes with a CoolProp DLL for 64-bit Windows. You may need to compile CoolProp for your own environment for a compatible library.
