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

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

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

   Abstract : 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. READ MORE

3. 22. KEY FACTORS AND PROBLEMS IN THE PERFORMANCE OF KITCHEN VENTILATION SYSTEMS

   University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Author : ÁLVARO ROS; [2020]
   Keywords : RESTAURANT KITCHEN VENTILATION; KITCHEN HOOD; VENTILATION SYSTEM; AIRFLOW; AIR QUALITY; PRESSURE DROP; HOOD PERFORMANCE; EFFICIENCY;

   Abstract : Regarding the great importance of a good working environment, in this research, ventilation systems installed in kitchens of restaurants were studied in order to avoid problems and to understand the key factors that can influence on the performance of the system. The results obtained were taken into account to provide some recommendations to a real ventilation system of a restaurant called Pastaria in Gävle (Sweden). READ MORE

4. 23. Modelling of a Generic Aircraft Environmental Control System in Modelica

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Sabin Poudel; [2019]
   Keywords : ECS; Environmental Control System; Modelica; Object oriented Modeling; TTECCS library; bootstrap system;

   Abstract : This thesis documents the modelling of generic Environmental Control System(ECS) of an aircraft in Modelica by utilizing components from free version of theTTECCS (Technical Thermodynamic Environmental Control and Cooling Systems) library. In doing so, components used for developing ECS from the TTECCS library are mathematically verified with theoretical formula in MATLAB. READ MORE

5. 24. Potential measures and improvements in energy consumptions regarding ventilations systems with heat recovery

   University essay from KTH/Byggteknik och design

   Author : Suat Uludag; Helmut Diliwi; [2019]
   Keywords : Ventilation System; System upgrade; Heat recovery; Energy consumption; Ventilationssystem; Systemuppgradering; Värmeåtervinning; Energianvändning; Energiförbrukning;

   Abstract : The ventilation system is in itself a huge necessity in our everyday life as it provides sufficient amount of fresh air to our indoor climate, while it simultaneously circulates the residing air pollutants out of the building. Although, for this to be made possible, large amounts of energy is required to be consumed, which in turn leads to an increased energy cost. READ MORE

6. 25. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.

   University essay from Mälardalens högskola/Framtidens energi

   Author : Yash Khanna; [2019]
   Keywords : Hybrid electric aircraft system; Thermal management system; micro channel; Dynamic modelling; Mobil Jet Oil II;

   Abstract : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.
