   Sammanfattning : Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. LÄS MER

3. 2. Modeling of waste heat recovery system and outdoor swimming pool : Waste heat from hotel kitchen recovered by heat exchanger transferred to pool

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Linn Olanders; [2020]
   Nyckelord :Heat exchanger; heat recovery; waste heat; pool; swimming pool; comsol; modeling; commercial kitchen; kitchen;

   Sammanfattning : This project was performed to evaluate if waste heat from hotel kitchens is enough to heat outdoor swimming pools in southern Europe or if it can be used as a compliment to another heat source. Another aim was to analyze the simulations and calculations of the pools and the heat recovery system. LÄS MER
