Physiological thermal response in typical air conditioning Environment

Thermal modeling of mini-channel and laminated Types evaporator in mobile air conditioning system

In this paper, mini-channel type evaporator which is new in mobile air conditioning (MAC) or automotive air conditioning (AAC) systems is thermally modeled. The performance of mini-channel evaporator is also compared with the laminated evaporator which is being currently used in automotive industries. The mini-channel evaporator was constructed of two rows of parallel flow mini-channel tubes...

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...

Air Conditioning Check and Air Conditioning Service

Physiological and subjective responses in the elderly when using floor heating and air conditioning systems.

The purpose of this study was to investigate the effects of a floor heating and air conditioning system on thermal responses of the elderly. Eight elderly men and eight university students sat for 90 minutes in a chair under the following 3 conditions: air conditioning system (A), floor heating system (F) and no heating system (C). The air temperature of sitting head height for condition A was ...

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 ...
