Guțul, Vera I.; Colda, Iolanda; Guțul, Vera G.; Usturoi, Liubovi

The paper is dedicated to the technical and economic analysis of air-conditioning solutions for office buildings. În this paper two air conditioning systems were compared: the variable refrigerant flow (VRF) system and the chiller-fan coil system. Comparison of the technical and economic indicators was done using the "global cost" method. As a result of the analysis, it was found that: the energy saving in the air conditioning system to a great extent depends on building design solutions and the type of air conditioning system.
