Here three RHVTs were used. 3rd situation deals with the six cascade type RHVT. In this case, six RHVTs were used. When all the test results under P-i = 360 kPa and P-i = 400 kPa pressure conditions are compared, it is found that the best performance occurs at the 3rd situation. Moreover, the performance of the 3rd situation at P-i = 400 kPa pressure is higher than that at P-i = 360 kPa. Maximum values of Delta T and xi are obtained as 67.6 degrees C and 0.9 for 3rd situation. (C) 2011 Elsevier Ltd and IIR.
