Design and Simulation of VRF AC system in cinema hall using ammonia refrigerants

This study presents the modeling, simulation, and validation of a dual-zone Variable Refrigerant Flow (VRF) air-conditioning system using ammonia (R-717) as the working fluid in MATLAB/Simulink. The system comprises detailed subsystem models i.e compressor, condenser, expansion valves, evaporators, and a building therm...
