Re-designing district heating networks through innovative CO2 solutions

District Heating Networks Calculation and Optimization

The first step in studying the behavior of a pipe network is to identify the objectives that must be attained and the physical and logical problems that must be solved; this aim can be achieved by building a suitable model of the network. The next step must be the operation of the model (which, for example, in the case of numerical models consists of using an appropriate algorithmic procedure) ...

Numerical modelling of district heating networks

Efficient Physical Modelling of District Heating Networks

A mathematical physical model for dynamic simulation of flow and temperature in district heating networks (DHN) is proposed. The network structure is described by means of a graph-theoretical approach where the network elements are pipe sections, consumers and heat sources. The governing equations for hydraulic flows and heat distribution through pipe networks are presented. In addition, proper...

Thermo - hydraulic simulation of district heating networks

Current developments of the European energy markets are influencing the operation strategy of heat suppliers. Especially providers of district heating systems fed by conventional heat production (i.e. CHP) have to react with appropriate measures to these changes. The integration of thermal storages, decentralization of the heat production, changing heating technologies or adjusting the temperat...

Designing the Attitude toward Advertising Model through Mobile Social Networks

The aim of this research is to help advance a better understanding of digital advertising innovation adoption, consumer acceptance of customized advertising, and the influence of customized advertising on product purchase intent via a mobile social network. To this end, two types of questionnaires, including an open questionnaire filled up by 16 experts and university professors was designed to...
