摘要

Office buildings represent one of the great energy consumers. The Lighting systems and HVAC are the greatest consumers. The energy consumption for cooling the areas will increase in the future due to the higher and higher internal heat emission and to the use of glass covered facades. The solar shading devices can substantially reduce the cooling load of buildings. Due to the geographical position of Romania, the solar radiation intensity shows high values. In this paper, a comparative study is performed on the energy consumption of the air-conditioners of the type: CLIMAVENETA NFCCI 1003 4 pipe-fan coil units, mounted in a room which does not have any shading elements on the exterior facade. In the second case the room is provided with shading elements formed by mobile exterior horizontal blinds. After the calculations made, it results a reduction of 29% in the energy consumption of the air-conditioning apparatus when shading elements are used.
