1. Evaluation of Modular Thermally Driven Heat Pump Systems
Sammanfattning : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.

2. Capacity Control of Residential Heat Pump Heating Systems
Sammanfattning : Heat pumps used for space and sanitary hot water heating of residential buildings are increasingly popular in northern Europe. As they compete with other heating equipment and in order to limit the environmental impact of their use, it is very important that heat pumps are energy efficient. LÄS MER
3. Experimental Investigation of Refrigerant Charge Minimisation of a Small Capacity Heat Pump
Sammanfattning : Enormous quantities of heat are available in air, soil, water, exhaust air from buildings, and in waste water of any kind. However these heat sources are use-less for heating purposes since their temperatures are lower than the tempera-ture required for heating. LÄS MER
4. Smart Energy Grids – Utilization of Space Heating Flexibility
Sammanfattning : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. LÄS MER
