1. 1. Air-to-water heat pump optimization with a photovoltaic system

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Andreas Rannanpää; [2022]
   Keywords : Photovoltaic; air-to-water heat pump; load regulation;

   Abstract : Photovoltaic systems and heat pumps installations are increasing faster than ever before in Finland. Load regulation is becoming a hot topic in the PV market. With load regulation, the self-consumption can be increased, and the user may earn money. READ MORE

3. 2. Energy analysis between traditional hot water circulation system and an innovative pipe-in-pipe system

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Alejandro Abellán Guallarte; [2022]
   Keywords : Hot water circulation; pipe-in-pipe; energy saving; buildings; heat losses; warm water;

   Abstract : We are at a time when energy efficiency and the reduction in the use of non-renewable energy is an important objective in all aspects and will continue to be so, therefore it is necessary to try to reduce energy and heat losses in the systems used in homes and, in particular, in the domestic hot water (DHW) system. This study aims to find out the advantages and disadvantages of an innovative pipe-in-pipe (PIP) system for DHW circulation with respect to the conventional system of two separate pipes. READ MORE

6. 5. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Pranjal Jain; Khaled Alturkmani; [2021]
   Keywords : Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

   Abstract : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. READ MORE
