The images illustrate a new design adsorption chiller that uses a refrigerant (ammonia) to produce power at the same time as cooling. The design is slightly different from the basic adsorption chiller in that a rotary machine can be attached for power production.  The system is enhanced by a mass recovery process from the refrigerant desorption from one adsorbent bed to the evaporator. The cycle can be run either in cooling mode or in cogeneration mode.  Manual regulating and automatic pneumatic valves are used in both fluid circuits in order to control the direction of the fluids.

Temperature and pressure sensors are installed around the ammonia and water circuits to collect data while others are connected to control heating and cooling processes according to the set-up temperatures. Pneumatic valves are connected to the control panel to drive the hot and cold water stream in the correct direction according to the program and also to control the ammonia mass recovery process.
