1. 31. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jaakko Eskola; [2023]
   Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

   Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE

3. 32. Analysis of energy efficient heat and lighting systems in a subarctic greenhouse

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : William Sigvardsson; [2023]
   Keywords : Energy efficiency; Sub-arctic greenhouses; Energy measures; Greenhouse climate control; Greenhouse technology; CFD;

   Abstract : This report studies a subarctic greenhouse located in Nikkala, Sweden called Nikkala handelsträdgård. Through a visit to the greenhouse coupled with the creation of two simulation models this study investigates the differences in energy demand with water-carried and air-carried heating systems, high pressure sodium lights and Light emitting diode lights and insulation in parts of the greenhouse without a active cultivation.
