Abstract

The summer months are increasingly seeing a lot of hot days. Therefore, increasing demands for air conditioning in dwelling houses, hospitals, hotels, workspaces, and the other commercial buildings. In many countries air conditioning is the biggest consumer of energy in the buildings. Reducing energy consumption we can achieve in different ways.The article deals with reducing energy for cooling the various alternatives ventilation and solar cooling. The room under simulation was ventilated by six methods. Of these 6 cook lowest energy consumption and CO₂ production had ventilation 90% overnight and 10% over day. Subsequently, using absorption refrigeration unit, powered by heat from the sun. In this case the power consumption is reduced to a minimum.
