Study of the Effect of Refrigerant Collection Tank on the Performance of the Evaporator in the Refrigeration System

To enhance the coefficient of performance (COP) for the evaporator within the cooling cycle, we initially designed, assembled, and executed the fundamental pressure cooling cycle. Subsequently, we introduced a novel component, the coolant group tank, strategically placed directly in front of the evaporator. The essential elements of the basic pressure cooling cycle encompass the compressor, condenser, expansion valve, and evaporator. Additional components include a thermostat, liquid flow meter, pressure gauge, temperature gauge, filter, examination valve, and the aforementioned cooling tank. Following the successful installation of the cooling cycle, we will activate the system and commence the collection of critical data, such as pressure and temperature readings at designated points throughout the process, to facilitate calculations and assess the performance of the evaporator. The experiment was replicated using the same cooling cycle; however, this time, we isolated both the cooling collection tank and the examination valve prior to gathering the necessary temperature and pressure data at specific locations within the system. We then recalculated to verify the evaporative performance. A comparative analysis of the data obtained from the first experiment, which yielded a COP of 7.5, and the second experiment, which achieved a COP of 9, revealed that the evaporative coefficient of performance was significantly higher when utilizing the coolant group tank compared to operating the cooling cycle without it.
