LoginVentilation is necessary to insure acceptable indoor air quality as well as to protect the building itself against damage due to condensation Ventilation rates however, must not lead to excessive energy consumption In order to comply with these re

Assessment of energy impact of ventilation and infiltration of the French regulations for residential buildings. | 1993 | English
The efficiency of removing excess heat by employing mixing ventilation is based on the properties of jets. Therefore the behaviour of jets in enclosures is important.
Ventilation codes for swimming pools are based on preventing condensation. To save energy, air recycle with dehumidification is common.
A total of 177 measurements have been performed in apartments in multi-story buildings without mechanical ventilation. The buildings comprised renovated and non-renovated buildings built between 1930 and 1960.
For several years the technology of chilled ceilings has been a favourite issue among HVAC technicians and underwent a boom in the past few years.
The Influence of Purpose-Provided Openings on Natural Ventilation of Buildings Equipped with Gas Fired Appliances. | 1993 | English
The growing diffision of small power, gas-fired individual units for space heating and service hot water production, as well as concern about operational safety issues, has promoted greater attention to the understanding of ventilation mechanisms
The issue of energy consumption assessment is a complex one.
The paper will describe the development of the storm safety value, experience of its use and suggestions for use in other connections.
In order to speed up the development of health, energy-efficient buildings, the City of Stockholm has formulated a programme for the building of apartment houses.
For thermal comfort and energy conservation reasons, displacement ventilation and radiative cooling systems are increasingly used.
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.
Correlations between CO2 and Steam concentrations Measured in 60 Occupied Housing Units. | 1993 | English
Within the framework of demonstration and industrial pilot projects in the energy sector supported by the Commission of the European Economic Communities, an important experiment has been dedicated to the HYGRO-ADJUSTABLE NATURAL VENTILATION (Cont
Ventilation efficiency measurements in a test chamber with different ventilation and cooling systems. | 1993 | English
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.
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.
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.
The importance of natural ventilation, typically restricted to residential buildings application, is rapidly increasing also within the commercial buildings.
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.
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.
Computational fluid Dynamics (CFD) is a powerfizl tool for analysing problems of air movement and has been increasingly widely used in applications in buildings.
