Renewable Energies - Photovoltaic Laboratory
LERF

LERF was built, in part using the European Regional Development Fund, over a period of about three years, with the inauguration taking place in December 2015. Its design and functionality were outlined by INCEMC researchers who have been considering the creation of a center of excellence in renewable energies, with an emphasis on solar energy. In the western part of Romania, the use of renewable energies is investigated in large universities, so the direct conversion of solar energy into electricity seemed to be the best approach when designing LERF. According to the researchers, LERF is a core element in the development of a cross-border excellence pole, integrating organizations from the western area of Romania and the neighboring countries which share similar aims.

 

LERF is energy-autonomous, due to the electric power provided by photovoltaic cells (1200 m2) of different types, located on the neighboring INCEMC hall, and also due to the geothermal air conditioning system. The laboratory possess a fully independent (off-grid) three-phase 10 kW photovoltaic system, built in AC bus topology. Also, the on-grid (coupled with the power supplier) photovoltaic system of the laboratory is one of the most efficient sources of electricity obtained from solar energy. The power of the installed panels (of various types) exceeds 80 kW, and the unused energy is injected into the national energy system.

 

The building’s geothermal air conditioning system consists of a water-water heat pump with simultaneous heat production, cold/hot water and energy recovery. The system features a highly efficient heat recovery (54 % in summer and 63 % in winter), a 50/40 °C warm water battery with 96 kW capacity, and a 7/12 °C cold water cooler with a capacity of 105.6 kW.

 

LERF is located in Timișoara (Romania), at 144 Prof.dr. Aurel Păunescu-Podeanu Street. It has four levels (basement, ground floor and two upper floors) and includes research facilities equipped with state-of-the-art technology and related spaces. The building easily stands out because, unlike the neighboring tarnished buildings, it changes its color depending on the angle of illumination and observation. The chameleon-dyed aluminum plating plays a more important role than just aesthetics. It provides shielding against ambient electromagnetic radiation and ensures the optimal conditions for the operation of the laboratory’s demanding research equipment. The electromagnetic shielding of the building was all the more necessary because there is a high-to-medium voltage transformation station in the vicinity of the laboratory.
