Thermodynamic Analysis Of Closed Steady Or Cyclic Systems, Jim A. Mcgovern
Thermodynamic Analysis Of Closed Steady Or Cyclic Systems, Jim A. Mcgovern
Articles
Closed, steady or cyclic thermodynamic systems, which have temperature variations over their boundaries, can represent an extremely large range of plants, devices or natural objects, such as combined heating, cooling and power plants, computers and data centres, and planets. Energy transfer rates can occur across the boundary, which are characterized as heat or work. We focus on the finite time thermodynamics aspects, on energy-based performance parameters, on rational efficiency and on the environmental reference temperature. To do this, we examine the net work rate of a closed, steady or cyclic system bounded by thermal resistances linked to isothermal reservoirs in …
Energy Savings Across Eu Domestic Building Stock By Optimizing Hydraulic Distribution In Domestic Space Heating Systems, Ciara Ahern, Brian Norton
Energy Savings Across Eu Domestic Building Stock By Optimizing Hydraulic Distribution In Domestic Space Heating Systems, Ciara Ahern, Brian Norton
Articles
The objective of this work is to quantify the resultant savings across the EU from the optimization of existing system components in domestic space heating distribution systems to maintain comfort levels. Heat energy savings are shown to range from 1% to 19% depending on dwelling type, age, location and initial specific heat energy consumption.
