Abstract :
In the present investigation, the feasibility of cooling load and power
consumption effect of a water-to-air heat pipe based heat exchanger (HPHX) on an office building
was studied. An office building in Chabahar Maritime University, in southeast region of Iran, which
is considered as a high cooling load demanding region, was chosen as the case study. The present
research uses the TRNSYS software to investigate the hourly responses of the existing system added
with the water-to-air HPHXs in terms of indoor air conditions and monthly power consumption. The
effect of added water-to-air HPHXs on the system was determined, and the results were compared with
the existing situation. Water-to-air HPHXs with two, four, and six numbers of rows were examined to
recommend the most appropriate configuration for the system. According to the simulation findings,
the existing system with the added six-row water-to-air HPHX is capable of establishing the
convenient air into the office space. Moreover, it was shown that by implementation of the six-row
water-to-air HPHX, a total amount of 3,108.57 kWh power, which is about
42%, could be saved in a year.
