چکیده
District heating and cooling systems have been undergoing continuous development now reached the fifth-generation. In this innovative technology, connected buildings share local excess energy that otherwise would be wasted, which consequently reduces primary demands carbon emissions. To date, issue of implementing fifth-generation district on existing has received scant attention, our research addresses challenging gap by proposing a novel method for designing these systems. We first explain possible thermal interactions between buildings, then present an analytical solution network balance, pipe design, prediction fluid temperature under fixed difference control strategy. The was validated against numerical simulations performed 11 located in Lund, Sweden using Modelica models. A diversity index metric also included models to assess efficiency system building cluster. results from solutions were complete agreement since is equation-based modelling language. developed pave way towards future investigations different strategies new business arise shift

A Novel Method for Designing and Optimization of Networks
In this paper, system planning network is formulated with mixed-integer programming. Two meta-heuristic procedures are considered for this problem. The cost function of this problem consists of the capital investment cost in discrete form, the cost of transmission losses and the power generation costs. The DC load flow equations for the network are embedded in the constraints of the mathematica...
متن کاملPhotoreversible micellar solution as a smart drag-reducing fluid for use in district heating/cooling systems.
A photoresponsive micellar solution is developed as a promising working fluid for district heating/cooling systems (DHCs). It can be reversibly switched between a drag reduction (DR) mode and an efficient heat transfer (EHT) mode by light irradiation. The DR mode is advantageous during fluid transport, and the EHT mode is favored when the fluid passes through heat exchangers. This smart fluid i...
متن کاملTheoretical analysis of a novel combined cooling, heating, and power (CCHP) cycle
This study presents a theoretical analysis of a new combined cooling, heating, and power cycle by the novel integration of an organic Rankine cycle (ORC), an ejector refrigeration cycle (ERC), and a heat pump cycle (HPC) for producing cooling output, heating output, and power output simultaneously. Three different working fluids—namely R113, isobutane, and R141b—have been used in power, ref...
متن کاملOn District Heating and Cooling Research in China
The growth of the Chinese district heating sector has been very rapid during recent years. No other country in the world can show the same rapid growth of district heating systems during the last decades. Heated building area increased six times between 1995 and 2008 according to the Chinese district heating statistics. China has also enjoyed strong growth of scientific articles and papers publ...
