The evaporator, adiabatic and condenser
of thermosyphon equal tree section. Ten thermocoupleswere installed to data Yogokawa MV1000 data acquisition with ±0.7oC accuracy, it used with type-K thermocouple ±0.5oC accuracy (22 points attached). Cmeasurement temperature-range) was used with type Kthermocouples to the inlet and outlet of the heating jacket and cooling jacket,thermocouple were attached to the TPCT and data logger were recorded. These were three points on the condenser, three points on the evaporator and three points on theadiabatic section.
