Design of Solar Thermal Combined Power and Cooling System Using LiBr-Water as Working Fluid

摘要

The integration of power and vapor absorption refrigeration cycle overcomes the disadvantages of power used for the compression refrigeration and also produces additional power (low pressure turbine) for other purposes. The integration is done by making the heat exchanger and generator as common and separate super heater and reheater is used to run the high pressure turbine (HPT) and low pressure turbine (LPT). The maximum total power output of 69.78 kW and 31.86 kW is obtained for HPT and LPT at the atmosphere temperature 30°C and separator temperature 180°C. At the same collector exit and atmosphere temperature shows the maximum cooling output of 188.88 kW. The additional advantages of integrating the power and cooling cycle's shows the choice of choosing the need of only power only cooling and both power and cooling. The analyses are done for various separator temperature and strong solution concentration.
