The project is a detail study of Energy Balance in cutting line station in Sandvik Mining and construction group. The aim of the project is reducing temperature and making a temperature balance inside the cutting line. During the recent years, many changes occur in production line. Existing cooling system cannot supply cutting area temperature below the desired level. Electrical Cables are melting due to high inside temperature. We attempted to study the old drawings and existing cooling system in cutting station to find out solutions to optimize and rebuild the old system. First part of study contains checking of preliminary air and water cooling system drawings. In the second part we looked at the operating cooling system by measuring different available working conditions such as inside temperature, air velocity and cooling water flow rate with different measuring equipment. The study integrate hot and cold stream (cooling air and water system) at different temperature level and in different times through production or non-production hours. Finally results and solutions can give valuable guidance for enterprises on how cooling systems should be expanded, what sizes should the new equipment have, where should the heat recovery exchangers be built, what new pipelines are needed, etc. To find more accurate results, we tried to do all measurements simultaneously, but due to difficult working condition it was not possible to have all input data at the same time. According to the primary data energy consumption during different times and Peak consumption amounts were calculated. Results consider the differences in cooling system effects inside the cutting line and the system which generates more cooling load and needed more improvements. The summer and winter conditions are different inside the work area. The simultaneous assurance of ventilation, energy reduction and occupant health remains a design challenge. Working area is a unman area; therefore environmental impact are not considered in this research.
