What is Bell Coleman Cycle?

The Bell Coleman Cycle, also known as the Reversed Brayton Cycle, is a refrigeration process where air is used as the refrigerant. In this cycle, air is compressed, cooled at constant pressure, expanded to lower its temperature, and then used to absorb heat from the space to be cooled. This cycle is commonly used in air refrigeration systems, especially in aviation, due to its simplicity and effectiveness in high-altitude environments.
