Cooling ceilings are more and more proposed, in order to eliminate excess heat in office buildings without consuming much energy in air transport. On the other hand, piston ventilation is proposed to efficiently eliminate contaminants.

Ventilation efficiency measurements in a test chamber with different ventilation and cooling systems. | 1993 | English
The Influence of the Humidity on Thermal Comfort, Heat Load Calculation and Cooling Capacity. | 1993 | English
This paper shows the extensive influence of humidity on comfort, cooling load and refrigeration capacity. Modern computer programs allow an effective consideration of humidity in systems.
In conjunction with IEA Annex 18, DCV-systems, a test on an auditorium in a school in Tyreso south of Stockholm has been carried out.
A new ventilation and cooling system called OKOMAIR has been developed and investigated. The main idea is to separate carrying off cooling loads and providing fresh air to the occupants without mixing it with the return air.
A combined thermal and ventilation model has been used to investigate the seasonal variation of air infiltration rates and ventilation heat losses in modern industrial buildings.
The air distribution in a room is investigated using computational fluid dynamics. Four common methods of supplying air to a room are compared.
The importance of natural ventilation, typically restricted to residential buildings application, is rapidly increasing also within the commercial buildings.
Computational fluid Dynamics (CFD) is a powerfizl tool for analysing problems of air movement and has been increasingly widely used in applications in buildings.
The effect of Various Inlet Conditions on the Flow Pattern in Ventilated Rooms - Measurements and Computations. | 1993 | English
A test room which was built at a scale 1:5 to the original one has been used to investigate air-conditioned rooms. The original room was specified by the international project IEA ANNEX 20.
Total energy exchangers with a rotating heat storing matrix have been applied to air conditioning systems for more than 25 years with very good results for saving both heating and cooling energy.
The role of ventilation in the housing stack is to provide fresh air and to dilute internally-generated pollutants in order to assure adequate indoor air quality.
This paper presents the results of monitoring the ventilation in Netley Infants School in Hampshire.
The number of smokers differs mainly with age, sex, education, profession, and cultural background.
Designing a comfortable inside climate for office buildings to operate within comfort limits (PMV+/-0.5) requires a flexible operating strategy. Two systems a VAV and a VHV are identified and compared to each other.
Mechanical Ventilation System with Heat Exchanger in One Room - Low Cost Mechanical Ventilation System. | 1993 | English
A new miniature mechanical ventilation system with both supply and extract air and an air-to-air heat exchanger has been developed in Great Britain and Denmark.
Existing regulations concerning the design and construction of residential buildings which are naturally ventilated via courtyards and lightwells have origins in daylighting rather than in aerodynamics.
This paper reports results from the ventilation and air tightness measurements in Swedish dwellings as part of the 1992 Swedish Energy and Indoor Climate Survey (the ELIBstudy).
Mechanical ventilation with heat recovery (MVHR) and passive stack ventilation (PSV) systems are both proposed as methods of ensuring satisfactory ventilation rates in UK housing.
Several demonstration buildings were constructed in order to find technical solutions to energy saving and better indoor air quality in the 1980's in Fiand.
Natural Ventilation in 18 Belgian Apartments: Final Results of Longterm Monitoring. | 1993 | English
In the framework of a CEC demonstration project on humidity controlled ventilation, detailed measurements are carried out in 18 apartments in Namur, Belgium.The paper gives a brief description of the building, of the airtightness of the apartments
