Bell Coleman Air Refrigeration Cycle

About Bell Coleman Air Refrigeration Cycle

          The Earliest type of refrigerator works on the bell Coleman cycle with air as working substance. The isothermal process from Carnot cycle are replaced by constant pressure process. The schematic diagram of Bell Coleman cycle Can be as...

      Bell Coleman cycle consists of compressor, expander, heat exchanger, and evaporator. The air from evaporator is drawn into compressor and is compared to heat exchanger pressure isentropically. During compression along with presser rise, temperature of air also increase. This warm compressed air is forced into heat exchanger, which cool the air at constant pressure. It has an effect of reducing volume from 3 to 5. Simultaneously it's temperature also reduces due to rejection of heat . This low temperature air is drawn into expander, Where it is expanded isentropically. This isentropic expansion reduce the temperature of air bellow that of evaporator temperature. This air at least temperature is passed to evaporator, where it absorb heat at constant pressure and produce refrigeration effect.
