Operation o Solar Photovoltaic-Thermal (PVT) Hybrid System in KIER

Abstract

The details of the Photovoltaic Thermal (PVT) hybrid air heating system, UTC air heating system and its effect on the performance of photovoltaic (PV) module and room temperature in KIER are explained in this paper. Two identical test rooms were constructed such that one had unglazed transpired collector on its south facing wall while other had no solar wall. The temperature inside the room with UTC was 10-20oC higher than the temperature inside the room without UTC on a typical winter day. In second set of experiments, 75W PV modules were installed on the south facing walls of each test rooms. The temperature of the PV module with UTC was 5-9?lower than the PV module without UTC resulting in a 6% recovery of output electrical power under the forced ventilation. PVT hybrid system may alleviate burden on conventional energy consumption in Korea for heating the buildings and electricity generation.
