The CLOHP/CV in this experiment was designed and developed
from 0.003 m inside diameter copper tubing and 26.40 m
total length per set of two check valves. The CLOHP/CV was
divided into three sections per set, i.e. the evaporator 1.50 mlong,
adiabatic gap 0.05 mand condenser, 0.30 mlong. The distribution
of the tubing is shown in Fig. 2. R-134a was selected as the
working fluid, and a filling ratio of 50% of the total volume of tube
was used. The CLOHP/CV arrangement was aligned at an
inclination angle of 18 degrees from the horizontal plane, with 6
turns per set. The condenser section was inserted in a condenser
