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
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.
Energy-saving improvements in the thermal properties of buildings often have an adverse effect on indoor air quality, leading to risks of structural deterioration.
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.
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.
Describes wind tunnel investigations made with Kr as a tracer.
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
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
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.
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.
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.
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.
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 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.
In order to estimate air change rates (ACH) on Natural Ventilation (NV) processes a number of factors should be known as general and openings dimensions, pressure distribution over the facades, internal heat sources (or sinks) and head losses.
Ventilation air intake - first line of defence against an unfavourable outdoor climate. | 1999 | English
The ventilation air intake (louver) is the first line of defence against an unfavourable outdoor climate.
Microbial investigations and allergen measurements in ground-coupled earth-to-air heat exchangers. | 1999 | English
Different ground-coupled earth-to -air heat exchangers have been constructed in many residential and occupational buildings in Switzerland to precool or preheat the incoming air. Many technical and energetic facts favour such systems.
The combined wind and stack effects on the induced air flow volume in a two-story building through the investigation of wind velocity, solar insulation, and roof design. | 1999 | English
One sixth of the total energy consumed in Taiwan is for building operation, mainly for summer cooling. The energy consumed for summer cooling can be greatly reduced if naturalventilation can be exerted in Taiwanese urban apartments.
