Summary

The mechanical vapor compression (MVC) system is a promising way for energy saving among energy intensive industries such as desalination, food and beverage, chemistry and waste water concentration etc. In practical its application is limited by the vapor compressor technology which is demanded to have high pressure ratio for large saturation temperature difference and low discharge vapor temperature. Due to the ability of wet compression, twin screw compressor can overcome the technical limitation above by the injection of liquid water into the working chamber. In this paper a test rig of a MVC system with water injected twin screw compressor has been designed and built. Compressor performance of power consumption and discharge temperature was measured. Moreover, operation characteristics of the water injected twin screw compressor were studied by the measurement of its working process p-t diagram. The results of the experiment study can provide some design guidance of water injected twin screw water vapor compressor for MVC system.
