As thermosyphon and all the other free cooling systems can only
work in cool season, mechanical refrigeration systems have to be
equipped for hot season. Two sets of equipment lead to double
initial investment, double installation space and control difficulties.
Integrated system of mechanical refrigeration and thermosyphon
(ISMT) is an ideal solution. Okazaki and Seshimo [20] and Lee et al.
[21] are among the earliest to design this kind of system. In their
design, thermosyphon and mechanical refrigeration shared an
evaporator and a condenser. However, the cooling capacity of their
systems was small therefore the energy-saving potential was
limited. To improve the capacity, Han et al. [22] proposed an
improved ISMT and applied it in cooling of data centers. A selfoperated3-
way valve, a new evaporator and different connection
pipes were developed to enhance the performance. Solenoid valves
were used to achieve switching between the mechanical refrigeration
mode and the thermosyphon mode.
