Abstract
Refrigeration is indispensable for a wide array of applications, ranging from household cooling to industrial freezing. Traditionally, mechanical methods have been utilized to transfer heat between different temperature reservoirs. However, the quest for energyefficient and low-maintenance systems has propelled innovations in refrigeration technology. One such innovation involves optimizing the utilization of flash gas within the system. This gas, if allowed to traverse the evaporator, can gradually deteriorate its components, resulting in heightened maintenance demands. To mitigate this issue, our modified system integrates a flash chamber downstream of the expansion device, such as a capillary tube. This chamber effectively segregates the flash gas from the liquid refrigerant. In our design, the separated flash gas is channeled into a shell and tube heat exchanger positioned adjacent to the condenser. Here, the flash gas circulates the tubes of the heat exchanger, efficiently extracting heat from the refrigerant flowing within the tubes. This strategic utilization of flash gas not only enhances the overall efficiency of the refrigeration system but also minimizes wear and tear on the evaporator components. Moreover, the outlet of the flash gas is connected to the inlet of the compressor, completing the cycle. By harnessing flash gas in this manner, our modified system not only enhances energy efficiency but also reduces maintenance requirements, offering a sustainable and economically viable solution for refrigeration needs. This innovative approach underscores the transformative potential of system modifications in advancing refrigeration technology, in line with the growing demand for environmentally friendly and efficient cooling solutions
