LoginThe continual reduction of the transmission heat losses of residential buildings causes an increasing importance of the ventilation heat losses. Energy saving can be achieved by using a mechanical ventilation system with heat recovery.

High quality is a prerequisite for industry to sell its products.
Theoretical basis for assessment of air quality and heat losses for domestic ventilation systems in France. | 1993 | English
Ventilation of buildings is necessary, both to insure adequate indoor air quality and to protect the building itself against condensation and mould growth. On the other hand, ventilation rates must not lead to excessive energy consumption.
The BRE method of predicting water vapour conditions in houses is based on two generalised moisture admittance parameters a and p.
Under-estimating the ventilation flow rate results in increased sanitary risks and damage to the existing building structure. Over-estimating ventilation flow leads to energy waste.
The paper presents a criterion to assess the performance of mechanical exhaust hoods for dome stic kitchens and a procedure to experimentally test them; an analysis of the relevant parameters which affect their performance is made, the test result
The momentum balance on a centrifugal fan, supplemented by a complete energy balance for rigorous interpretation of power-pressure interactions, relates these variables to flow rate and fan speed.
Many modern office and residential buildings in Sweden include an atrium. The atria are often mechanically ventilated and sometimes they are heated. Very little is know about the ventilation and air infiltration in built atria.
In urban non-residential buildings air-conditioning systems are generally required to achieve acceptable air quality. To reduce the energy demand of HVAC-plants free cooling is proposed.
Increases in the levels of thermal insulation required in the walls and roofs of houses in the U.K.
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.
Dynamic insulation stands for an insulation through which an air flow flows. The air flow is usually the normal ventilation flow. The air can flow in the same or in the opposite direction of the normal heat flow.
Assessment of energy impact of ventilation and infiltration of the French regulations for residential buildings. | 1993 | English
Ventilation 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
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.
Ventilation codes for swimming pools are based on preventing condensation. To save energy, air recycle with dehumidification is common.
The paper will describe the development of the storm safety value, experience of its use and suggestions for use in other connections.
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.
For thermal comfort and energy conservation reasons, displacement ventilation and radiative cooling systems are increasingly used.
