eng POSSIBILITIES OF HEAT LOSS REDUCTION DURING HOT WATER PREPARATION IN RESIDENTIAL BUILDINGS
Lukáč, Peter; Záhorský, Peter
The holistic approach to environment
Vol. 3, No. 4, 2013
The aim of the article is based on an analysis of heat losses arisen before the renovation of hot water distribution pipeline of a selected residential building and after the subsequent renovation is to design possibilities for more efficient insulation. Three alternatives of insulation thickness in terms of heat loss along with the condition of the existing isolation after the renovation of the distribution pipelines and with the condition before the renovation are compared in the article. By choosing a suitable insulation, energy efficiently...

Transformers Magazine
Vol. 6, No. 5, 2019
The aim of the article is to provide the reader with the basic concept of the transformer’s heat utilization where a proposed technical solution anticipates the installation of an additional oil-water heat exchanger (ODWF) in the transformer's cooling system. An increase in the transformer’s cooling capacity lowers the oil temperature and reduces the transformer’s loss of life expectancy. In order to estimate the transformer’s oil temperature profile, as well as the heat power potential at the water side of the ODWF cooler, a numerical investig...
