Heating and Cooling Degree Days under Local Jordanian Conditions

摘要

Heating and cooling degree days were studied for seven localities in Jordan. Weather data was obtained from Meteorological Department of Jordan and the results were compared with those obtained from Retscreen and other researchers for HDD and with Retscreen only for CDD. It was found that heating degree days were slightly lower than those reported previously and that is probably due to an increase in ambient temperature of about 1℃ per year. Cooling degree days for the same locations were found at two base temperatures,T_b = 24 and 22 ℃. The latter was found to be more realistic due to the above reason. Both HDD and CDD were compared with values obtained through Retscreen and it was found that that those obtained from the latter show higher values of HDD and much higher values of CDD.
