Coaxial personalized ventilation system and window performance for human thermal comfort in asymmetrical environment -

Antoun, Sylvie Jacques, (2015)

This paper assesses the energy performance and occupant comfort of a ceiling mounted coaxial personalized ventilation system in presence of radiation asymmetry due to a large window for different glazing systems. Detailed ...
Displacement ventilation with cooled liquid desiccant dehumidifier membrane at ceiling : modeling and design charts -

Hout, Mohamad Badih, (2017)

A novel transport model is developed for a space conditioned by a cooled liquid desiccant dehumidification membrane ceiling (LDMC-C) and displacement ventilation DV in which the space is divided into three zones: an occupied ...
Effective desiccant dehumidification system with two-stage evaporative cooling for hot and humid climates -

El Hourani, Mario George, (2013)

This study examines the design and operation of a hybrid air conditioning system that uses 100percent fresh air and integrates a solid desiccant dehumidification system with a two-stage evaporative cooling system to optimize ...
Effectiveness of upper-room UVGI systems in spaces conditioned by localized air conditioning systems : enhancing air quality and energy performance -

Kanaan, Mohamad Issam (2015)

Providing thermal comfort and good indoor air quality (IAQ) at minimal energy cost has been considered a priority in the field of heating, ventilation, and air conditioning (HVAC) for the past couple of decades. It is ...
Energy efficient strategies for reduced cross-contamination between occupants in office spaces -

Habchi, Carine Hanna, (2016)

IAQ in indoor environments is one of the major concerns of public health organizations. People constitute one of the main sources of particles carrying contaminants in indoor environments by exhalation resulting from the ...
Fresh air personalized ventilator systems for occupant-controlled microenvironment

Makhoul, Alain Hanna. (2013)

The project aims towards integrating more than one air distribution system by separating the fresh and recirculation air supply system in an effort to lower fresh air needs and to substantially reduce the air conditioning ...
Liquid desiccant dehumidification membrane ceiling-displacement ventilation system effectiveness with optimized operational strategy -

Muslmani, Mohamad Eljawad Hasan, (2015)

The performance of the chilled ceiling (CC) displacement ventilation (DV) systems is constrained by latent load removal capacity and associated cost of supply air dehumidification to prevent condensation on the chilled ...
Optimized operation of a solar hybrid desiccant - displacement ventilation combined with personalized evaporative cooler

Hammoud, Mohammad Ali. (2012)

The study investigates by modeling and experimentation the performance of a hybrid air conditioning system that operates in humid climate and conditions the room by displacement ventilation (DV) aided with personalized ...
Optimized performance of displacement ventilation aided with chair fans for comfort and indoor air quality -

Abou Hweij, Walid Mohamad Jamal, (2016)

This study optimizes the performance of displacement ventilation (DV) system aided with chair fans (CF) for providing acceptable thermal comfort and indoor air quality (IAQ) in office space. A 3-D computational fluid ...
Optimizing performance of ceiling mounted personalized ventilation system assisted by chair fans : assessment of thermal comfort and indoor air quality -

El Fil, Bachir Khaled, (2015)

This study investigates and optimizes the performance of ceiling mounted personalized ventilation (PV) system when assisted with chair-mounted fans. Detailed computational fluid dynamics (CFD) simulations were performed ...
Predicting steady two-phase flow of refrigerants under variable heat flux

Hachem, Mohamad Majed (2020)

Two phase flow of refrigerants during evaporation and condensation subjected to variable heat flux is being studied. Several types of refrigerants (R134a, R12, R22, R32 and R143a) are being studied as the internal fluid ...
The use of condensate drain to pre-cool the inlet air to the condensers : a technique to improve the performance of split air conditioning units - Riad Ibrahim Sawan.

Sawan, Riad Ibrahim. (2011)

Air conditioning (AC) split systems experience a drop in their coefficient of performance (COP) in response to the hot ambient conditions since their condensation and the ambient temperatures are directly linked. Research ...
