Impact of PV/T system on energy savings and CO2 emissions reduction in a liquid desiccant-assisted evaporative cooling system

초록

The main thrust of this research is to estimate the energy savings and CO2 reduction potentials acquired by integrating photovoltaic/thermal (PV/T) system into the established liquid desiccant-assisted evaporative cooling system. The PV/T system provides the electric power and hot water simultaneously, which are required to operate the liquid desiccant unit in the established system. The required capacity of the PV/T system can be determined for the peak electric load or peak thermal load of the liquid desiccant-assisted evaporative cooling system. Consequently, energy simulations were performed for PV/T integrated system alternatives; the one is designed for the peak electric load, and the other is for the peak thermal load. The result shows that the PV/T system sized for the electric load may provide more than 10% of primary energy savings and CO2 emissions reductions compared with the PV/T system sized for the peak thermal load.
