INTRODUCTION Radiant heat gain to the head has recently been shown to affect sensation in human subjects (Buyan et al., 2006). However, only one published study has been conducted on the influence of radiant heat gain for sports headgear (Ishigaki et al., 2001). One could assume that reducing heat stress by shielding solar radiation using sports headgear would increase thermal comfort, and poss...

Radiant cooling systems (RCS) are gaining acceptance as a heating, ventilation, and air conditioning (HVAC) solution for achieving adequate thermal comfort maintaining acceptable indoor quality inside buildings. RCS well known their energy-saving potential; however, serious condensation problem hinders the growth of this technology. In order to prevent risk condensation, supply water temperatur...

This paper entails an empirical and computational assessment of the air flow field in close proximity a vertically positioned radiant cooling panel. solution differs from conventional large-area systems (e.g., ceiling panels). It involves rather small-sized vertical panels to occupants. Moreover, are designed so as manage potential surface condensation water vapor via integrated drainage elemen...

Generally, Central Asia is typical for regions with strong solar radiation and various natural cooling sources. The heat gain from the building envelope accounts for a large part of the cooling load there. Thus, the pipe-embedded envelope is receiving attention as a semi-active system of utilizing natural energy for cooling. In this study, the performance of the pipe-embedded envelope used in U...
