  1. 1. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies

    University essay from KTH/Energiteknik

    Author : Hsin-Ting Ko; [2020]
    Keywords : Demand flexibility; Heat pump; IDA ICE; Smart grid; Thermal comfort; Thermal inertia; Bottom-up simuleringsmodell; efterfrågeflexibilitet; Demand response; energiteknologi; slutanvändarbeteende; grön byggnad; VVS-systemkontroll; värmepump; IDA ICE; smart nät; termisk komfort; termisk tröghet;

    Abstract : 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.

  4. 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

    University essay from SLU/Dept. of Economics

    Author : Erik Boije; Gustaf Eskhult; [2014]
    Keywords : water-related illness; cost-benefit analysis; India; atmospherical water; solar disinfection; water supply; clean drinking water;

    Abstract : 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.

  5. 4. Experimental Analysis of Variable Capacity Heat Pump Systems equipped with a liquid-cooled frequency inverter

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Thair Ebraheem; [2013]
    Keywords : inverter-driven compressor; liquid-cooled inverter; variable capacity heat pump; variable speed compressor;

    Abstract : 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. READ MORE

  6. 5. Experimental analysis of variable capacity heat pump system equipped with vapour injection and permanent magnet motor

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Umer Khalid Awan; [2012]
    Keywords : heat pump; variable capacity; scroll compressor; vapour injection; permanent magnet motor; R410A;

    Abstract : 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. READ MORE
