    Vapour Compression Refrigeration system (VCRs) has been extensively used in Refrigeration and HVAC sectors due to its beneficial characteristics like higher COP and Refrigerating Effect. However, these sectors and consequently VCRs contribute to a substantial and rapidly increasing global energy consumption which has raised huge concerns. This project aimed to experimentally analyse the vapour compression refrigeration system and compare performance of the system with and without heat addition. It was conducted by fabricating a VCR unit and adding extra heat to the unit before and after the compression process. The COP of the system increased by 46.07% when heat was added before compressor while the current consumption of the compressor decreased by 12.07%. However, COP of the system decreased by 22.7% when heat was added to the system after compressor with 32.6% increase in current consumption.
