Název v původním jazyce

Air, ground massif low-temperature energy sources

Popis výsledku v původním jazyce

The aim of this study was to analyze and compare the impact of two low-temperature energy sources, air and linear horizontal ground heat exchanger (HGHE), on the energy effect of a heat pump and their contribution to fulfilling the objectives of reducing fossil fuel consumption. The results of operational verification and statistical analysis showed that linear HGHE is a more favorable low-temperature energy source for heat pumps than air in terms of expected energy effects. The set of temperatures of the heat transfer fluid from a linear HGHE showed higher average and median values, and less variability in comparison with the corresponding set of air temperatures. Temperatures of the fluid in linear HGHE were positive over the entire heating period and more than 73% of the data were higher than the temperatures of air. A higher value of the energy effect of the linear HGHE expressed by a comparative coefficient of performance, epsilon(h) of reversed Carnot cycle, also showed higher benefits of this
