The main research objective of this paper was to compare exergy performance of three different heat pump (HP)-based systems and one natural gas (NG)-based system for the production of heating and cooling energy in a single-house dwelling. The study considered systems based on: 1. A NG and auxiliary ...

In this paper, the possibilities of developing machine learning based data-driven models for the short-term prediction of indoor temperature within prediction horizons ranging from 1 hour up to 12 hours are systematically investigated. The study was based on a TRNSYS emulation of a residential build ...

This paper presents the results of a thermo-economic (TE), primary-energy-factor and CO2-equivalent (CO2 (eq)), emissions-sensitivity analysis for the preparation of sanitary hot water (SHW) in fourth-generation district-heating systems. The annual required additional heat for the SHW provided by a ...

In the last 3 years in Slovenia we experienced extremely hot summers andThe results show that energy use for heating would decrease from 16% to 25% (depends on the intensity of warming) in subalpine region, while in Mediterranean region the rate of change would not be significant. In summer time we ...

The condensation of humid air is a crucial step in air conditioning and process engineering. However, the models that describe the condensation of vapour in the presence of a non-condensable gas require time-consuming numerical calculations that go beyond the Nusselt film theory. Only a small number ...

Drevesno-pašna raba je v svetu prevladujoča oblika kmetijsko-gozdarske rabe v Sloveniji pa je glede na naše danosti še premalo prisotna. Zatem, ko vzpostavimo vegetacijo primerno za to obliko rabe kmetijskega zemljišča, je potrebno preveriti tudi možnosti za agronomsko izboljšanje obstoječe travne r ...
