Abstract:

Heat Pumps are becoming one of the most considered mechanical conditioning equipment in our buildings. While they are popular, there appears to be quite a vast range of system types and applications in building conditioning. This paper primarily reviews the literature on heat pumps, the various types, and the consideration of design end uses. The fact that there are different energy sources for heat pumps is considered, as well as the different sinks in which energy is stored or dissipated. It is evident that advanced heat pump systems cater well to the use of renewable energy resources. There

To reduce CO-emission, Air/Water and Air/Air heat pumps are increasingly used in the Netherlands. Due to several noise complaints, the Dutch government decided that legal regulations were necessary to restrict outside noise. The legislation process consisted of three phases. Determination of noise limits on neighbouring plot boundaries, based on a comparison with existing noise regulations for small companies in a defined quiet living environment. Creation of rules for ground-bound dwellings and for apartments. Determination of the legal noise measurement procedure of installed heat pumps, suc
