THERMAL COMFORT OF TASK AIR CONDITIONING WITH ISOTHERMAL AIR FLOW UNIT

Thermal Comfort in Offices – Natural Ventilation vs. Air Conditioning

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

Implementation of adaptive indoor comfort temperature control via embedded system for air-conditioning unit

Environmental control strategy via computerized implementation is one of the most efficient approaches to integrate new advanced knowledge in research of human thermal comfort to a mechanical air-conditioning unit. Recently, a new conceptual development in designing air-conditioning systems has indicated that the indoor comfort temperature strongly depends upon changes of the outdoor air temper...

Air-conditioning, health and outdoor thermal comfort in some local cities.

comparable to Singapore in outdoor thermal comfort except in December and January. The inland stations of Kuala Lumpur and Petaling Jaya are, relatively, quite uncomfortable with the latter experiencing average ETs above 76°F for more than half of the year. The most interesting feature of the study is that the East Malaysian towns of Kota Kinabalu (KK) and Kuching (KU) M. IIyas MSc., Ph.D., F.R...

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...
