“…Bojić et al [4] compared three HVAC systems for heating and cooling of an office building. Wang et al [5] made a comparison of three HVAC systems for a hypothetical apartment building. The study included 17 climate zones with various temperature and humidity conditions, and the systems compared were a direct expansion split system, a split air-source heat pump system and a closed-loop water-source heat pump with boiler an evaporative fluid cooler.…”

Energy and Permanent link to this version:http://urn.kb.se/resolve?urn=urn:nbn:se:du-15163 Energy and Buildings 82 (2014) a b s t r a c tIn this paper, dynamic simulation was used to compare the energy performance of three innovative HVAC systems: (A) mechanical ventilation with heat recovery (MVHR) and micro heat pump, (B) exhaust ventilation with exhaust air-to-water heat pump and ventilation radiators, and (C) exhaust ventilation with air-to-water heat pump and ventilation radiators, to a reference system: (D) exhaust ventilation with air-to-water heat pump and panel radiators. System A was modelled in MATLAB Simulink and systems B and C in TRNSYS 17. The reference system was modelled in both tools, for comparison between the two. All systems were tested with a model of a renovated single family house for varying U-values, climates, infiltration and ventilation rates.It was found that A was the best system for lower heating demand, while for higher heating demand system B would be preferable. System C was better than the reference system, but not as good as A or B.The difference in energy consumption of the reference system was less than 2 kWh/(m 2 a) between Simulink and TRNSYS. This could be explained by the different ways of handling solar gains, but also by the fact that the TRNSYS systems supplied slightly more than the ideal heating demand.
