4 599! " = " + (10), " = " - +. / + " 0 (11), " = Net thermal resistance for a unit surface area, h 2 = Outside convection coefficient. h = inside convection coefficient 3 = Surface thermal conductivity. 4= Surface element thickness. According to Fayazbakhsh and Bahrami (2013), the outside convection coefficient is given as: h 2 = (12) where V= is the minimum vehicle speed \$ = 0.138,78 17 (13) \$ = , , = 1500 (14) According to Ding and Zito #2001&,h = 8.3 W/m 2 K! ' = " F,, ' =. / + " 0,! ( = " G,, ( =. / + " 0 iv Radiation load Radiation loads are obtained for both the glass surfaces and other surfaces of the car. Equations are the commonly used models for air conditioning calculations as suggested by ASHRAE (2001). Direct radiation load = LM H I H J K cosp (15) J K = Q R (16) STUV W A is the apparent solar irradiation taken as 1230W/m 2 for months of January to December and 1080W/m 2 for mid-summer while B is the atmospheric extinction coefficient which has a values of for the months of January to December. The declination, D is given as: X=23.47]^_ (`a #'bcdk& (`e Where day of the year starting from January, N= 21 for January 21, 2015 at Lagos, Nigeria Local Solar Time, LST = (2.00pm) Hour angle, h = 15(LST - 12) (18) Tilt angle, f = 0 (horizontal surface) and 90 o (vertical surface), Wall azimuth, ε= 0 o (southern surface), ε= 90 o (western surface) and ε= 180 o (northern surface) The altitude angle, is given as: β= sin g" #cos#h&ij]#h&cos#k&+sin#h&sin#k&& (19) L = latitude, h = hour angle, d = angle of declination, I= roof element transmissivity Since surface element transmissivity of roof, wall and floor is zero, the direct radiation through those elements becomes zero.
