The research subject of the current work is heating of the closed area by the forced air ventilation system with heat recovery ventilator and floor radiators. The simulation model was made in ANSYS Fluent 14.0. In the simulation were taken to account the secondary thermal gains from the computers, monitors and humans. The results of the simulation...

This study investigated the thermal and indoor environmental performance of an office building in the northeast of England. The building was built using natural stone and glass; internally the large floor plates are bordered and penetrated by open voids that ventilate the building and provide exceptional day lighting. A computational model for this...
Buildings that are designed to meet high-energy performance requirements, e.g., passive houses, require well-insulated building envelopes, with increased insulation thicknesses for roof, wall and floor structures. We investigate whether there are differences in the efficiency of thermal insulation materials at different moisture levels in the insul...
The passive house concept specifically improves insulation of exterior building components, utilisation of passive solar gains, airtightness and heat recovery from ventilation air. Reducing also heat losses from thermal bridges, the energy balance is improved significantly resulting in net heating demands lower than 15 kWh/(m²a) which is less than...
There are number of structural systems for timberframe houses, which differ in materials used in an external wall assembly and, in some cases more importantly, in level of pre-fabrication. Traditional systems would mainly consider light-frame (two-by-four) or heavy-frame (post and beam) structures built on site, or the same systems with minor alter...
This paper presents the analysis of airflow distribution in an open space room by means of CFD numerical simulation having as case study a pre-certified passive house, located in Cluj-Napoca. The ventilation system comprises two rectangular inlets, located on the floor near the glazing and six exhaust grilles of circular cross section located at th...

Air conditioning is a significant part of the contemporary life. A lot of the medical papers confirmed the influence of the thermal comfort to the operability. The aim of the article is to understand the system of the building ventilation with the HRV unit. For this purpose, the CFD simulation model was elaborated. The ANSYS Fluent allows to calculate the heat balance of the room with secondary thermal gains like computers, monitors and humans. The results of the simulation approved that in the modern thermal passive houses heat balance calculations should take into account secondary thermal gains from the installed equipment. Also the air circulation in the closed area and the influence of the different barriers installed in the laboratory were investigated.
