1. Comparative Analysis of Modern Energy Systems for Ice Rinks
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. READ MORE

2. Aqua Ammonia as Secondary Fluid in Ice Rink Applications
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

3. Parallel CO2 refrigeration system compared to state-ofthe-art solution in supermarket application
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : This thesis compares the performance of two trans-critical CO2 refrigeration systems, the state-of-the-art booster system and the standard parallel system. The main goal is to quantify the efficiency difference between these two systems. By using computer assisted calculations both systems are modelled, then energy results are obtained. READ MORE

5. Studying the feasibility of installing a temperature independent snowmaking system with heat recovery : Case study for the ski resort of Astún
University essay from Högskolan i Gävle/EnergisystemAbstract : A research on analysing the feasibility and the benefits obtained from the utilisation of the heat surplus from temperature independent snowmaking systems is proposed. The interest of this research relies on the fact that it is a way of making it viable both economically and environmentally, to use these systems, which are the solution for snow scarcity due to global warming.
