Small Scale Solar Cooling Unit in Climate Conditions of Latvia: Environmental and Economical Aspects

The paper contributes to the analyses from the environmental and economical point of view of small scale solar cooling system in climate conditions of Latvia. Cost analyses show that buildings with a higher cooling load and full load hours have lower costs. For high internal gains, cooling costs are around 1,7 €/kWh and 2,5 €/kWh for buildings with lower internal gains. Despite the fact that solar cooling systems have significant potential to reduce CO₂ emissions due to a reduction of electricity consumption, the economic feasibility and attractiveness of solar cooling system is still low.
