Comparative analysis of VRF and fan coil systems for an education building

COMPARATIVE ANALYSIS OF VRF AND FAN COIL SYSTEMS FOR AN EDUCATION BUILDING SUMMARY People spend a large part of their time in the indoor environment. For this reason, it has always been in search of a comfortable environment for years to come. Nowadays, with the developing technology, suitable temperature values and air quality can be provided while automatic control can also be made. However, energy efficiency of heating-cooling systems has gained importance and studies are proceeding in this direction. In this study, VRF system and a fan coil system which has wide usage area as a heating cooling system, has been designed separately in an educational building has 7000 m2 closed area. The investment costs of the VRF and fan coil systems were compared with the operating costs for summer and winter periods. In addition, two system are examined for comfort conditions, noise levels, ease of operation, installation and commissioning and shown in the issues such as the plus and minus aspects of the system. While the design of heating-cooling systems is generally based on the needs of investors and the needs of the users, the other important element in the design is that the system is efficient. Calculating the energy consumption of heating and cooling systems and evaluating this calculation together with the initial investment cost will guide us to choose the right system. In this study, it is aimed to compare the efficiency analysis of the two systems by calculating the investment and operating costs of VRF and fan coil systems in an education building. In the assessments, in the selection of air conditioning system, the architectural features of the building, heat insulation and energy efficiency values of the devices used in the systems have an important role in energy costs.
