Net-zero energy technical shelter
Technical shelter for storing electronic and technical equipments has high indoor heat dissipation rate, and cooling load exists almost all year around. Energy consumption of cooling system takes majority of entire energy use. Our project aims in reducing the energy consumption by proper design of building envelop and optimal control of cooling system. Both experimental measurements and computer simulation are carried out to analyze the indoor climate and energy performance of technical shelter in different conditions. The experiments are made on a standard technical shelter. Vertical temperature gradient and air flow rate are measured by thermocouples and tracer gas technology. Energy balance is calculated by simplified analysis method based on measurement results. Simulation program BSim is applied in the study. The simulation results are compared with measurement results. Finally, PV system is planned to build on the roof to power technical shelter. Both off-grid and on-grid PV systems are designed based on PVSYST software. ...
