<p>Carbon dioxide (CO<sub>2</sub>, R-744) has been identified as a promising alternative to conventional working fluids in a number of applications due to its favourable environmental and thermophysical properties. Previous work on residential CO<sub>2</sub> heat pumps has been dealing with systems for either space heating or hot water heating, and it was therefore considered interesting to carry out a theoretical and experimental study of residential CO<sub>2</sub> heat pump systems for combined space heating and hot water heating – so-called integrated CO<sub>2</sub> heat pump systems. The scope of this thesis is limited to brine-to-water and water-to-water heat pumps connected to low-temperature hydronic space heating systems..</p>
