Development of a Steam Jet Refrigeration Cycle for the Actual Application Driven by Low Grade Thermal Energy
چکیده انگلیسی

The aim of this paper is to develop the jet refrigerator and test it under the actual ambient condition in Thailand. The prototype steam jet refrigerator with a cooling capacity of 3000W is newly designed and constructed. It is driven by low grade thermal energy. In this case, the LPG burner is used to simulate the heat source for driving the boiler. The geometries of the ejector are fixed throughout the test. Two primary nozzles with its throat diameter of 3.3 and 3.8 mm are used to test the system performance. They produce the nozzle's exit Mach number of 4. The refrigerator is used to produce the chilled water at various cooling load. The results indicate that the prototype jet refrigerator can completely be operated at the actual ambient condition in Thailand where the cooling water temperature produced by cooling tower is between 29 and 33 °C. The maximum COP of 0.45 is achieved when the refrigerator is operated at boiler temperature of 110 °C, evaporator temperature of 17 °C, and cooling capacity of 3000W.
