This field study was organized to determine the ventilation required to maintain acceptable air quality in a retail store using the ASHRAE Standard 62-1989 performance-based procedure.

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.
Liddament M W
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

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.
Saraiva J G, Marques da Silva F
The ventilation air intake (louver) is the first line of defence against an unfavourable outdoor climate.
Kristiansen O, Hanssen S O, Stang J, Lysne H N
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.
Flueckiger B, Monn C
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.
Chao N-T, Chiang C-M, Wang W-A
A patented, low energy, fresh air fan convector has been developed by a HVAC equipmentmanufacturer in conjunction with a leading controls supplier and a local University.
Price M J, Clancy E M
Air handling units do not always function as planned: airflow rates are often larger than required, the recirculation rate is not at its set-point value and parasitic shortcuts sometimes decrease dramatically the ventilation efficiency.
Roulet C-A, Foradini F, Deschamps L
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.
Geissler A
This technical note considers the performance evaluation of an advanced air-conditioningsystem in a plant manufacturing electrical generators.
Raisanen J, Paakkari A, Niemela R
Air exchange rates of ten residential buildings were measured according to ASTM-E741-83 using SF6 as a decaying tracer.
Alper E, Elkilani A S, Bouhamra W S
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.
Streifel A J, Bridges B B, Grimsrud D T, Krafthefer B C
Energy-saving improvements in the thermal properties of buildings often have an adverse effect on indoor air quality, leading to risks of structural deterioration.
Baumann M-L, Amphoux A
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.
Anisimov S
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.
Pasanen A V, Liesivuori J
Describes wind tunnel investigations made with Kr as a tracer.
Dutsuik T, Jablonskiy K, Leonteva U
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

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
