1. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies
Master-uppsats, KTH/EnergiteknikSammanfattning : Sweden is undergoing energy transition to become a zero-carbon economy with electricity production aims at 100% from renewable resources by 2040. Sweden also has a national goal to have fossil-free vehicle fleet by 2030. The increasing share of intermittent renewable resources creates growth in mismatches between electricity supply and demand.

2. Development and application of a multidomaindynamic model for direct steamgeneration solar power plant
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies. LÄS MER
3. With a few liters of clean drinking water : a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of EconomicsSammanfattning : In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water.

4. Experimental Analysis of Variable Capacity Heat Pump Systems equipped with a liquid-cooled frequency inverter
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : Using an inverter-driven compressor in variable capacity heat pump systems has a main drawback, which is the extra loss in the inverter. The present experimental study aims to recover the inverter losses by using brine-cooled and water-cooled inverters, thereby improving the total efficiency of the heat pump system. LÄS MER
5. Experimental analysis of variable capacity heat pump system equipped with vapour injection and permanent magnet motor
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : This study analyzes the performance of variable capacity heat pump scroll compressor which is equipped with vapour injection and permanent magnet motor. Refrigerant used in the system is R410A. The study is divided in two phases. In first phase, tests are carried out for heat pump without vapour injection. LÄS MER
