5. Free cooling and PVT integration in a ground-source heat pump (GSHP) system
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE
