Influence of air flow patterns in a room on evaporation and humidity distribution around a heated wet cylinder. | 1999 | English
Air flow patterns in rooms can roughly be classified as one of three types: Displacement flow, source flow and mixed flow. Displacement flow in its original meaning is only used in special applications like clean rooms.
The pattern of airflow influences the propagation of airborne pollutants, the thermalenvironment and general comfort conditions.
The main objective of this study was to determine the ventilation demand for a gymnasium inthe primary school based on verified metabolic rate.Norwegian guidelines recommend 6.0met as the activity level to be used when calculating the outdoor air
The Paper deals with numerical computations, carried out, in order to predict the effects of natural convection on the thermal performance of porous material.
Prediction of air flow in a single-sized naturally ventilated test room using artificial neural networks. | 1999 | English
The objective of this research is to investigate thermal comfort and air flow distribution insidea test room which is naturally ventilated. The test room is ventilated through adjustablelouvers.
Low temperature heating systems: impact on IAQ, thermal comfort and energy consumption. | 1999 | English
The Netherlands Agency for Energy and the Environment(NOVEM) is conducting a program for the implementation of Low Temperature Heating (LTH) systems in buildings. The primary goal is to enable the use of Low Talued Energy as a heating source.
Development of a demand control strategy in buildings using radon and carbon dioxide levels. | 1999 | English
Air change rates, indoor radon and carbon dioxide levels were monitored in a lecture theatre in the Hong Kong University of Science and Technology.
Use of the global warming potential index to evaluate the impact of reducing air infiltration rates in existing houses. | 1999 | English
In a cold climate such as of Montreal the air infiltration through the exterior envelope of a house has a significant impact on the heating energy consumption and cost.
Energy loss due to ventilation: impact of average values and simplifications on calculations. | 1999 | English
The project of CEN Standard from the Ventilation for dwellings group TC156/WG2/AH4 [1]for airflows calculations is being submitted to enquiry.This method can be easily compared to AIVC guides to calculate the ventilation airflow(natural or mechani
Chinese food is delicious. There are many kinds of cuisine. But the stir-fry, fry and deep-fry produce a large amount of steam and smoke which cause indoor air pollution seriously. So it must be controlled.
Appraisal of building envelope alternatives in terms of overall physical performance. | 1999 | English
The envelope as fictional building element acts as a filter intended to regulate energy andmass flows. The overall performance of the envelope is ascertained by the combined effects ofthe functional components.

Comparison of indoor air quality between air-conditioned building and naturally ventilated building during heating season. | 1999 | English
Field measurements were made during the heating season to compare IAQ between an air– conditioned building (Building A) and a naturally ventilated building (Building B) situated in the centre of Pyongyang and similar in architectural design, numbe
The energy saving practice of stopping ventilation systems at night may reduce the daytimeair quality.
The improvement of air quality due to self-restricted air consumption in regions as well as globally appears to have considerable promise.
The purpose of this study is to provide a model to facilitate the simulated evaluation of theenergy consumption for different mushroom house and climate set point configurations.Climate management in this application is complex, including control
Three buildings are investigated to study the indoor air quality and the impact of the outdoorair pollution. These buildings, a swimming pool, a school and a nursery are located in anurban area.
Two energy-efficient single-family houses (known as ESPI houses) with competitive overallcosts were set up during the study in Finland.
Rooms with high windows are likely to have comfort problems caused by cold airdowndraught, which are usually solved by placing heating appliances underneath thewindows.
