Abstract
In this study, vertical type ground source heat
pump (GSHP) was used to heat a restaurant located in Istanbul province and to
meet the usage hot water requirement. The designed system is simulated with the
help of the TRNSYS (time dependent system simulation) program then its
performance and energy consumption are examined. While room temperature was
kept constant at 22 ºC in winter with the help of the GSHP system, 300 l/h of
water at 55ºC was drawn to use for 15 minutes during the whole year (at 06:00
a.m., 08:00 a.m., 20:00 p.m. and 22:00 p.m.). The rated heating capacity of the
heat pump used is 78228 kJ/ h and the rated power consumption is 18193 kJ/h. As
a result of the analysis, the total annual power consumption of the GSHP system
is 3922.88 kW,
the annual average performance coefficients of the heat pump and the whole
system are calculated as 3.33 and 1.81 respectively. Of the energy consumption
were obtained as 54.36% by
the heat pump, 26.78 % by electrical heaters, 13.64% by
pumps and 5.22% by fan.
