Steam jet refrigeration system.
• The Steam Jet Refrigeration System utilizes a steam ejector/eductor to create vacuum in the evaporative glass container.
• Water is chosen to be the refrigerant or cooling media just like in real application, a larger system uses water steam as the motive gas to create suction in evaporator chamber.
• The trainer uses an electric boiler system to create the steam required to operate the eductor.
• The pressure of the steam Generator Tank is controlled by pressure control circuit and can be varied by changing the pressure limit on the pressure controller.
• The effect of changing motive gas pressure to eductor performance can be seen
• Inlet, Suction and Outlet of the eductor ports are connected to pressure gauges to monitor the pressure of each port. A needle valve also provided to do variation on the suction volume which will influence the time required to get such value of cooling effect. An electric heater is put inside the evaporator to supply heat to the cooling media.
Pressure and temperature of various points can be monitored and analyzed to get the conclusion.
