How does the vapor compressor contribute to the energy efficiency of a Vapor Compression Distillation (VCD) system?

The vapor compressor in a Vapor Compression Distillation (VCD) system contributes to energy efficiency by increasing the pressure and, consequently, the temperature of the vapor produced during evaporation, allowing it to be reused as a heating source. In VCD, seawater is evaporated at a relatively low temperature and pressure. The resulting vapor is then drawn into the compressor, which increases its pressure. According to the laws of thermodynamics, increasing the pressure of a gas also increases i....
