RES use is significant part in energy sector in Latvia and in neighboring countries, so the new solutions Electricity, Heat and Cool production using different RES including Solar Energy are searching for. Due to the significance of maintaining an optimum indoor microclimate during the summer, for example, in hotels and office buildings, manufacturing premises etc., which has mainly concrete and glass structures, explore small-scale use of solar refrigeration technical potential and sustainable development. In Baltic Sea region climate conditions cooling are required about 3000 - 5000 degree hours per year. In Latvia solar cooling system is not used yet, so it is important to assess the potential of such systems. In the Institute of Physical Energetic at Solar Energy Testing park the Solar Cooling system is installed with the cooling capacity 8 kW in the facility, measuring equipment is connected and operating data have been monitored and technical equipment performance were improved. The paper presents new methods for effective solar energy use for cooling on experimental developed base. The results of solar cooling investigations will be considered to evaluate the potential of these technologies, analyzing its strengths and weaknesses, as well as promoting innovative technology transfer from science to the practice.
