  1. 1. Comparative Analysis of Modern Energy Systems for Ice Rinks

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pendar Hemati; [2023]
    Keywords : Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    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

  3. 2. Geographical Mapping of the Building Envelope Surface Optimal Optical Properties Minimizing the Energy used to Maintain Indoor Conditions

    University essay from Högskolan Dalarna/Energiteknik

    Author : Alejandro Rodríguez-Urdaneta; [2020]
    Keywords : buildings; energy efficiency; energy savings; energy simulations.; edificios; eficiencia energética; ahorro de energía; simulaciones energéticas.;

    Abstract : Several studies have shown that the buildings envelope optical properties are important in terms of energy use and thermal comfort level. However, no study has been found in regard of the optimal optical properties for the building envelope. READ MORE

  4. 3. A pilot study for a possible installation of Photovoltaic modules at The University of Havana : Bachelor's thesis in a field study in Havana, Cuba

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Caroline Eliasson; Elin Rahmqvist; [2018]
    Keywords : Photovoltaic modules; Cuba; Matlab; LCOE; Fotovoltaiska moduler; Kuba; Matlab; LCOE;

    Abstract : In 2014 the Cuban government announced that 24% of the country’s generated electricity will come from renewable energy sources by 2030. In Cuba the emissions have drastically risen over the past decade due to the increasing amount of electricity demand. Today most of the generated electricity is produced by burning oil. READ MORE

  5. 4. Use of Gravity Sensors for Free Space Orientation

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Victor Garcia-Fernández; [2015]
    Keywords : Kalman; Particle filter; Fixed-point math; MSP430; Kalman; Partikelfilter; fast punkt matematik; MSP430.; Kalman; filtro de partículas; álgebra de punto fijo; MSP430;

    Abstract : This thesis deals with different approaches to filtering the signal output of a three axis accelerometerfor free space orientation, that is, finding the orientation of a sensor relative to gravity. Theplatform this orientation system is to be developed for is a low-power, high-efficiency fixed-pointmath microprocessor, therefore efficiency and mathematical operation precision are factors thatalso need to be taken into consideration in this work.

  6. 5. Control algorithms for energy savings in irregularly occupied buildings

    University essay from Avdelningen för bygg- energi- och miljöteknik

    Author : Angel Luis Sanz Aceituno; [2013]
    Keywords : Control algorithms; Energy savings; control; IDA; IDA ICE; Radiators; Nighttime strategies; feedforward controller; Ahorro energético; radiadores; algoritmos de control; IDA; IDA ICE;

    Abstract : The Heating, Ventilation and Air Conditioning (HVAC) systems are nowadays in almost every new building, develop or improve better control strategies for them is very common, looking to have more energy efficiency and require less input parameters from the user. In this project, new control strategies based in previous theory models has been used with a new approach in order to find a good solution for irregular occupied spaces. READ MORE
