The effect of Various Inlet Conditions on the Flow Pattern in Ventilated Rooms - Measurements and Computations. | 1993 | English
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.
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.
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.
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.
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.
An even distribution of room air can improve indoor air quality, lower energy costs, and create thermally comfortable environments. This paper investigates the influence of the design of plaque diffusers on the efficiency of supply air.
The PLEIADE Dwelling: an IEA Task XIII Low Energy Dwelling with Emphasis on IAQ and Thermal Comfort. | 1993 | English
The major objective of the IEA task XIII project is to design and construct low energy dwellings which should be technically and economically realistic in the period 2000-2010.
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
The 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.
