Ventilation is pivotal both in terms of indoor air quality and environmental issues such as greenhouse gas emissions. It also has a major impact on energy use in buildings.
The development of guidelines for smart innovative mechanical ventilation systems is a task included in an ongoing research project partly supported by the European Commission in the framework of the Joule programme "TIPVENT - Towards Improved Per
Performance of an advanced air conditioning system during extreme weather conditions in a generator plant. | 1999 | English
This technical note considers the performance evaluation of an advanced air-conditioningsystem in a plant manufacturing electrical generators.
Computer simulation of building airtightness measurements shows the effect of changes inpressure distribution across the building envelope due to wind force and temperature differenceon measurement accuracy.
Air exchange rates of ten residential buildings were measured according to ASTM-E741-83 using SF6 as a decaying tracer.
This field study was organised to track differential pressure relationships in critical care units of a metropolitan hospital. Maintaining design pressure balances is essential to control risk of airborne disease transmission within these units.
This present work has theoretically investigated coupled heat and mass exchangemechanisms in counterflow rotary dehumidifier with the mixed desiccant of LiCl and additives,used in air conditioning systems.
Energy-saving improvements in the thermal properties of buildings often have an adverse effect on indoor air quality, leading to risks of structural deterioration.
Storage and processing oil contamination on new HVAC components: development of measuring methods. | 1999 | English
The HVAC components are usually made of galvanised sheet metal which is covered by a corrosion protection and also lubricant oils are used in machine tools in manufacturing of the components or ducts.
Method of air parameters control while processing in air-handling units of HVAC systems. | 1999 | English
Based on theoretical and experimental tests it was determined that the thermodynamic balancecondition in the working space of air-handling units (AHUs) of heating, ventilating and aircondltioningsystems (HVAC systems) is entirely defined by the hu
Describes wind tunnel investigations made with Kr as a tracer.
A humidity control system with an adsorption material and indoor air quality improvement. | 1999 | English
The present study introduces a humidity control apparatus which can hygienically and automaticlymaintain the appropriate humidity level of indoor air without either a water supply or drainage system.In humidification, the desiccant takes up water
In mechanical exhaust ventilated buildings in cold climates, the supply air through vents in the perimeter may cause draught and reduce the zone of occupancy. One way to prevent this is to preheat the outdoor air by a vent-convector.
Horizontal distribution of submicrometre particles from vehicle emissions near a major road: implication for building location. | 1999 | English
Particle characteristics in indoor environments are strongly related to the characteristics ofoutdoor particles. The aim of this work was to investigate how submicrometre particle numberconcentration changes with the distance from a road.
Natural devices in the urban spaces to improve indoor air climate and air quality of existing buildings. | 1999 | English
The role of outdoor spaces’ design as well as the mutual correspondence among urban microclimate, indoor air climate and air quality, have been specifically investigated for the case study of the Central Athens Area.
Suitable combinations of desiccant and evaporative cooling systems permit air processes alternative to the traditional ones for air conditioning applications.
Isolation rooms for Tuberculosis in fifteen hospitals have been surveyed and measured in twophases. In phase 1 the isolation rooms in seven hospitals were checked ater the hospitalsrenovation construction had been finished.
Design of ventilation routes and indoor air quality in houses using a passive ventilation system. | 1999 | English
The feasibility of designing ventilation routes in the house with passive ventilation system is investigated using the numerical experiments and the measurements on its ventilation rates and indoor air quality.
Design methodology and economic evaluation of central-fan-integrated supply ventilation systems. | 1999 | English
Residential ventilation systems can be categorized as supply, exhaust, or balanced systems.This effort focused on establishing a design methodology for central-fan-integrated supplyventilation systems.
