Introduction Introduction • The rate of power consumption for both

domestic and industrial usage is increased.• 15% of all the electricity produced in the

world is employed for refrigeration and air-conditioning.

• Combined power and cooling can reduce the usage of power to refrigeration and solar helps as renewable.

• Hence common working fluid is needed for integration.

Conclusions Conclusions Additional power of 9 kW is produced

due to high pressure turbine at 30 C ⁰atmosphere condition with 0.99 and 120 C of turbine concentration and ⁰

temperature respectively.Power efficiency is doubled.High separator pressure and temperature

is possible.
