Improve chiller efficiency with evaporative cooling

Energy consumption in Turkey has increased steadily and is an unavoidable fact that it will increase further in the coming years. The continuous increase in energy consumption has caused the need for energy efficiency to become more and more important. Our external dependence on energy, increasing energy costs and competitiveness reveals that energy efficiency should be considered as a new energy source. Turkey's 2017 - 2023 national energy efficiency action plans, energy consumption is occurring in 32.8% building sector, while 32.4% took place in the industrial sector and should be done in energy efficiency efforts in these areas are indicated. As of 2015, energy consumption in buildings has exceeded industrial energy consumption. In this study, the cooling system of an office building in Bursa is discussed. The thesis was prepared experimentally and water was sprayed on the condenser unit (evaporative cooling) in order to increase the efficiency of the cooling system (chiller). The condenser temperature has been reduced and the chiller cooling system provides an increase in the amount of cooling as well as an increase in the chiller efficiency through a reduction in electricity consumption. An evaporative cooling system project for the chiller system to protect the condenser system from corrosive effect was made and implemented. Before the project, the actual efficiency (COP) of the existing cooling system was measured and then the chiller condenser was cooled by evaporative method and its effects on the efficiency were investigated. As a result of the study, it was seen that the chiller yield increased by 11%. With the evaporative cooling application, it was determined that TL 7450 was saved annually. The increase in energy costs shows that this amount of savings increases gradually.
