AIR-CONDITIONING AND COMFORT.

open access: yesOccupational health review, 1965
Factors that affect thermal sensations of comfort including the role of radiative energy exchanges between various surfaces in the room are discussed. It is shown that limitations in the uniformity of conditions influencing comfort may be imposed by the nature of the room and its occupancy, by the system capability and controllability, and by the air ...

The value of air conditioning

open access: yesFrontiers in Energy Efficiency
The advent of global climate change and rising incomes, particularly in some developing countries such as Egypt, means that the use of air conditioning is poised for a dramatic increase over the next few decades. Although this anticipated increase appears inevitable, it is often associated with a negative connotation because of the increased energy ...
