Based on theoretical and experimental tests it was determined that the thermodynamic balancecondition in the working space of air-handling units (AHUs) of heating, ventilating and aircondltioningsystems (HVAC systems) is entirely defined by the hu

The present study introduces a humidity control apparatus which can hygienically and automaticlymaintain the appropriate humidity level of indoor air without either a water supply or drainage system.In humidification, the desiccant takes up water

Particle characteristics in indoor environments are strongly related to the characteristics ofoutdoor particles. The aim of this work was to investigate how submicrometre particle numberconcentration changes with the distance from a road.

In mechanical exhaust ventilated buildings in cold climates, the supply air through vents in the perimeter may cause draught and reduce the zone of occupancy. One way to prevent this is to preheat the outdoor air by a vent-convector.

The role of outdoor spaces’ design as well as the mutual correspondence among urban microclimate, indoor air climate and air quality, have been specifically investigated for the case study of the Central Athens Area.

Suitable combinations of desiccant and evaporative cooling systems permit air processes alternative to the traditional ones for air conditioning applications.
Schibuola L
Models are presented for describing the performance of room air cleaners in removing pollutants from indoor air, particularly the levels of removal that can be achieved in practice.

In order to explain the effect of heat recovery on a passive ventilation system using stack effect, and to show the factors and conditions that the heat-recovery system can be installed in a passive ventilation system, the following investigations

The goal of this study was to investigate the effectiveness of stand-alone modular airpurification systems in improving air quality in dental practices and certain hospital andlaboratory environments.

A test rig for long-term tests of activated carbon filters was developed consisting of eight parallel test-filter sections. The test-rig was installed on the roof of a six storey commercial building located in the centre of Goteborg, Sweden.

In recent years, increasing importance has been placed on energy efficiency in residentialbuildings. This has resulted in tighter buildings, which raises concerns about the amount ofventilation required to provide acceptable indoor air quality.
Kesselring J P
The performance of a hybrid air-conditioning system which utilises wind-induced cross ventilation is investigated.
Kato S, Murakami S, Chang H, Chikamoto T, Kim T
As part of an ongoing investigation on service life of air filtration material, a new type of airfiltration material (multi-layered polymer) was compared with a widely used material todetermine growth or survival of micro-organisms after normal du

This paper deals with the internal environment of traditional excavated dwellings in Santoriniand the effect the conditions of the surrounding volcanic rock have on it.
