Energy-saving estimation model for hypermarket HVAC systems applications
(Elsevier Science Sa, Lausanne, 2011)
Energy saving estimation model (ESEM) use normal distribution (Gaussian) probability theory to predict potential savings for previously determined system improvements. Those improvements are low/high cost investments based ...
Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
Experimental and numerical investigation of heat exchanger built in solid fuel household furnace of an original concept
(Elsevier Science Sa, Lausanne, 2005)
This paper presents selected results obtained by experimental investigation and modeling of flow and heat transfer processes, considering heat exchanger built within an originally developed concept of a household furnace, ...
Supply water temperature regulation problems in district heating network with both direct and indirect connection
(Elsevier Science Sa, Lausanne, 1998)
General form of equations for hot water temperature in house installation and district heating system according to the outside temperature are well known. The influence of heat exchanger type and its fouling on heat output ...
The influence of heat exchanger performances on the design of indirect geothermal heating system
(Elsevier Science Sa, Lausanne, 2004)
Geothermal water can be used for heating objects both by direct or indirect systems. Indirect heating system with supplementary heat source is analyzed in this paper, and mathematical model that includes heat transfer in ...
Experimental determination of fouling factor on plate heat exchangers in district heating system
(Elsevier Science Sa, Lausanne, 2012)
This paper presents the results of experimental research on 8 plate heat exchangers. Their purpose is to heat water for radiator heating system and domestic hot water. Measurements were carried out in 4 substations in ...
Automated identification of land cover type using multispectral satellite images
(Elsevier Science Sa, Lausanne, 2016)
Detection of specific terrain features and vegetation, referenced as a landscape classification, is an important component in the management and planning of natural resources. The different land types, man-made materials ...
Theoretical and experimental study of heat transfer in wall heating panels
(Elsevier Science Sa, Lausanne, 2015)
This paper presents the analysis of the impact of basic geometric parameters - pipe diameter and the spacing between the pipes, and technological parameters - volumetric flow and heating water inlet temperature, on a ...
CFD analyses for passive house with Trombe wall and impact to energy demand
(Elsevier Science Sa, Lausanne, 2015)
The paper deals with a comprehensive, three-dimensional numerical CFD analysis of temperature fields in Trombe wall and in the adjacent room for several days of a typical meteorological year (TMY) for a moderate continental ...
Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
