| Abstract |
This study examined the energy performance of a solar heating and cooling system for an public child care center by using the dynamic simulation program (TRNSYS). This solar heating and cooling system incorporates evacuated tube solar collectors of 229.5 m2, storage tank of 15 m2, 348.8 kW auxiliary heater and single-effect LiBr/H2O absorption chiller of 20RT nominal cooling capacity. As a result, the average daily efficiency of the heating and cooling collector were 36% and 34% respectively. The average monthly efficiency of the heating and cooling collector were 32% and 28%, and the share of the solar heating and cooling system for loads were 45% and 26%. And the average yearly collector efficiency of the system was 27%. and the share of the system for loads was 37%. |
