Water vapor compression and its various applications

The main applications of water vapor compressors can be divided into mechanical vapor recompression (MVR) system, water vapor heat pump system and water vapor refrigeration system. MVR system is a high efficiency and energy saving technology and its advantages lie in the simple process, low operation cost, simple structure and small covered area. Water vapor refrigeration and heat pump systems both face the challenges of evaporation in vacuum, big compression ratio, small volumetric refrigeration capacity, large volume flow rate and high exhaust temperature. Nevertheless, the coefficients of performance (COP) of them are better than the traditional refrigeration and heat pump systems under certain conditions. Some typical applications of water vapor systems with their own special characteristics are also introduced.
