A total heat absorption device for humid air was proposed as the research object,and a theo-retical model for heat exchange between air and salt solution was established.The heat transfer process was analyzed using the binary method.The effects of air inlet temperature,relative humidity of air,inlet temperature of salt water and mass flow rate of salt water in a direct contact heat exchange device on heat and mass exchange performance as well as condensation water volume and heat transfer were studied.The research results indicate that an increase in air inlet temperature and relative humidity will enhance the heat and mass exchange degree;the increase in temperature of salt water inlet will weaken the degree of heat and mass exchange,while the increase in mass flow rate of salt water can enhance mass and heat transfer.
