Abstract. This paper presents the effects of the passive solar
heating
of the individual housing unit located in Nis, which are brought about
by use of passive solar system made up of glass veranda and thermo
accumulative
cross brick wall having thickness of d = 20 cm and d = 45 cm. The
object
is not heated additionally by means of conventional energy sources. On
the thermo accumulative wall there are windows for direct absorption of
the sun radiation.
This paper also analyzes the inner temperatures in the room and in
the glass veranda, in the thermally isolated object with cross thermo
accumulative
concrete and brick wall having thickness of 20 and 40 cm. There have
been
given diagrams of the inner temperatures in the glass veranda and the
room
of the object for its different orientations: ? = 0° (orientation of
the
glass veranda towards the south, ? = + 80° (orientation of the glass
veranda
towards the east), ? = - 80° (orientation of the glass veranda towards
the west).
Key Words: Greenhouse, Passive Solar Heating of Residential
Objects.
TERMODINAMIČKO PONAŠANJE SOLARNE
STAMBENE
ZGRADE
SA VERANDOM I TERMOAKUMULATIVNIM ZIDOM
U radu su prikazani efekti pasivnog solarnog grejanja individualnog
stambenog
objekata, koji nastaju primenom pasivnog solarnog sistema, a sastoji se
od staklene verande i termoakumulativnog pregradnog zida od opeke
debljine
d = 20 cm i d = 45 cm. Objekat se dodatno ne greje konvencionalnim
energentima.
Na termo- akumulativnom zidu se nalaze prozori za direktan zahvat
sunčevog
zračenja.
Posebno su analizirane unutrašnje temperature u prostoriji i staklenoj
verandi, u toplotno izolovanom objekatu, sa pregradnim
termoakumulativnim
zidom od opeke debljine 20 cm i 45 cm. Dati su dijagrami unutrašnjih
temperatura
u staklenoj verandi i prostoriji objekta za njegove različite
orijentacije:
? = 0° (orijentacija staklene verande prema jugu), ? = + 80°
(orijentacijastaklene
verande prema istoku), ? = ? 80° (orijentacija staklene verande prema
zapadu).
Ključne reči: Staklena veranda, pasivno solarno grejanje zgrada
