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.

DİKEY TİP TOPRAK KAYNAKLI BİR ISI POMPASININ SİMÜLASYONU

Abstract

Bu çalışmada İstanbul ilinde yer alan bir restoranın
ısıtılması ve kullanım sıcak su ihtiyacının karşılanmasında dikey tip bir toprak
kaynaklı ısı pompası (TKIP) kullanılmıştır.
Tasarlanan sistem TRNSYS (Zamana bağlı sistem simülasyonu) programı yardımıyla
simüle edilmiş ve sistemin performansı enerji tüketimi açısından incelenmiştir.
Ele alınan mahallin sıcaklığı, TKIP sistemi yardımıyla kış aylarında 22 ºC’de
sabit tutulurken, tüm yıl boyunca günde dört kere (6:00, 8:00, 20:00 ve 22:00)
saatlerinde 15 dakika süreyle 55 ºC sıcaklıkta 300 l/h su kullanımı
gerçekleşmektedir. Kullanılan TKIP ünitesi nominal ısıtma kapasitesi 78228
kJ/h, nominal güç tüketimi 18193 kJ/h’dır. Analiz sonucunda TKIP sisteminin
yıllık toplam güç tüketimi 3922,88 kW, ısı pompası ve tüm sistemin yıllık ortalama
performans katsayıları sırasıyla 3,33 ve 1,81 olarak hesaplamıştır. Tüketilen
enerjinin %54,36’ü ısı
pompası, %26,78 ısıtıcılar, %13,64’ü pompalar, %5,22’i ise fan tarafından
tüketilmektedir.
