Solar Thermal Based Power and Vapor Absorption Refrigeration System

The system combines the refrigeration cycle and power generation cycle using solar thermal as source. The current dual effect VAR system has two generators, to meet the choice of only power/only cooling/both power and cooling. The strong refrigerant solution (aqua ammonia) from the absorber is divided in to two streams and one flows to the first generator and heats by solar thermal heat, then turbine. This produces the maximum power to the maximum vapour aqua ammonia as inlet to the turbine and these changes with temperature and pressure and made the cooler effect at exit of turbine. The balance mass goes to the second generator for refrigeration and it is single effect refrigeration. Thus the system cooling and power have been integrated to get two benefits from a single system.
