Özet
The aim of the current study was to investigate how to use hot water obtained by parabolic trough collector (PTC) in an air handling unit. The system consisted of a PTC, a water depot, a pump, an air handling unit, a fan, and control equipments. The purpose of the system was to maintain the set value without using an additional heater in the air handling unit. During the process, +/- 0.36 degrees C accuracy was achieved in a 40 degrees C set temperature. Uncertainty analyses were made for the measured temperature value and they were obtained as +/- 0.44 degrees C. The energy and exergy efficiency were calculated for the system. The heating performance coefficient (HPC) was defined as the ratio of the obtained energy from the system to the compulsory energy supplied to the system. The HPC was calculated as 3 on average. Heat energy of the water in the depot was converted to heat energy of the air in the system with an average 52 % exergy efficiency.
