Testing and optimizing the performance of a floor-based task conditioning system

Personal comfort models: Predicting individuals' thermal preference using occupant heating and cooling behavior and machine learning

“…These devices target sensitive body parts that can have a significant influence on the whole-body thermal comfort. Studies have shown that local cooling and heating via PCS can improve thermal satisfaction [58][59][60] and lead to higher acceptance of wider temperature excursions [52]. In recent years, a group of researchers at the Center for the Built Environment (CBE) at the University of California, Berkeley developed a new controller for PCS chairs that can record continuous streams of heating and cooling usage data, occupancy status, and environmental measurements (e.g., air temperature, relative humidity) via embedded sensors (See Figure 1) [61].…”

Temperature Stratification of Underfloor and Ceiling Based Air Heating Distribution System in an Experimental Room

“…DOI: 10.2478DOI: 10. /sspjce-2013 Some studies devote to the issue of air inlet and they show that the above mentioned hypothesis is true [5][6][7][8][9][10]. However, this system is necessary to verify also in the weather conditions of Slovakia.…”

Thermal evaluation of a chair with fans as an individually controlled system

“…Bauman et al (1993) categorized task conditioning systems into three types: floor-based, desk-based, and partition-based. Floor-based task conditioning systems have been developed and evaluated by Spoormaker (1990), Sodec and Craig (1990), Li et al (1994), and Bauman et al (1995). With regard to the desk-based task conditioning systems, several types of task units and systems have been developed (Arens et al 1991, Bauman et al 1993, Loomans 1999 Knudsen and Melikov (2005) developed and tested an individually controlled system (ICS) consisting of a personalized ventilation system, an under-desk air terminal device supplying cool air toward the front of the body, a chair with a convectively heated backrest, an under-desk radiant heating panel, and a floor radiant heating panel.…”
