    Abstract [en]

    In the summer of 2009, WSP visited a facility adjacent to the Tara-mine at Navan, Ireland. The purpose of their visit was to control the ventilation system which was outdated. During the visit the inspector detected that their heating system also was in need of updating and that task led to this bachelor thesis.

     

    The overall aim of this work is to investigate how a modern heating system can be assembled to improve the indoor climate compared to an older system, where the primary target is to develop a proposal for the formation of a new system that meet the power requirements and today's climate demands.

     

    The study refers to a facility used as a changing room for the miners and as an office premise. The analysis focuses on the changing rooms as the indoor environment is especially inadequate with temperature and relative air humidity above recommendatory values for good indoor climate. In addition, the system is heated with large amounts of oil which contribute with large contaminations to the environment. Being able to moderate the impact the facility contribute to the surroundings is an additional motive for any investment.

     

    The analysis began with an examination of the system demands from the facility’s needs, followed by a search of potential components which could optimize a contemplated system. In order to be able to build this system theoretically correct the thesis established a flow chart. On the basis of the flow chart, the system components is conform adjusted to the facility’s needs, which includes the heating of domestic hot water, ventilation- and heating systems, as well an air dehumidification unit in the locker room. To examine the possibilities of improving the energy efficiency of this heating system, the project will evaluate heat exchangers, a heat pump and a dehumidifier, and a coupling to the existing ventilation and heating systems.

     

    The results are presented as a theoretical system that reduces the facility’s energy consumption and improves indoor climate. By utilizing the accessible thermal energy, the project also presents the economic advantages from choosing an efficient heat pump within the system.
