Master Thesis: Development of a Thermodynamic Simulation Model of HSVA's Ice Model Basin

Introduction:

In the Large Ice Model Basin of HSVA model ice is grown using a compressor based refrigerant plant (Figure 1). The plant guarantees heat flux from water surface to the air volume in the basin hall and further transfer of heat from air to refrigerant in vaporizers. The actual temperature and heat flux are important for the model ice growth and are influenced by the parameters of cooling system and the boundary effects. In order to generate reliable input for a model ice growth prediction method, a basic thermodynamic model of the cooling system in combination with building structure, air volume and water basin (Figure 2, left) is required. The simulation model shall reflect the basic thermodynamic processes (Figure 2, right).
