The Armenian climate in general and the Yerevan climate in particular, are decidedly continental and are very dry, with average relative humidity of less then 20% most of the time in summers. Dry air usually helps to withstand the summer heat, when 40°C may be a common maximum temperature during 2-4 months.

The solar driven DEC machine naturally yields cold air (in our case about 17°C), that has humidity close to the upper comfort limit. When people enter into an environment that has relative humidity of more than 50%, despite of lower temperature, they feel discomfort. This fact suggests to target even at a lower temperature to compensate the “humidity” contrast that is taken negatively by the public in the auditorium. This also suggests customization of the “comfort standards” for regions that have dry climate.
