4. 2. Utilization of a GSHP System in a DHC Network : modeling and optimization

   Author : Anjan Rao Puttige; Thomas Olofsson; Ronny Östin; Staffan Andersson; Javed Saqib; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground source heat pump; district heating and cooling; optimization; borehole heat exchanger; artificial neural network; hybrid model; field measurements; calibration; heat pumps; prosumer;

   Abstract : The ground source heat pumps (GSHPs) of customers connected to the district heating and cooling (DHC) network can benefit both the customer and the energy company. However, operating the GSHP to minimize the cost of providing heating and cooling to the customer while ensuring the long-term stability of the ground temperature is a challenge. READ MORE

5. 3. Optimum Design of Heat Exchanger Networks in Retrofit Situations

   Author : Annika Carlsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

   Abstract : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. READ MORE
