effect thus produced at a very low cost isof great importance to hotels, theaters, banks, stores andoffice buildings, not only because of the increased cleanlinessand the more efficient work procured from the help due tothe cooler and more invigorating atmosphere, but as an in-ducement to customers to visit those shops where they maybe comfortable. Effect Upon Our Comfort: In very hot weather aspractically all the heat must be lost by evaporation with thehigher temperature, perspiration is greatly increased in order toprovide the required evaporation. The flow of perspirationto the surface of the skin is dependent upon the heat generatedin the body and the pores of our skin, not unlike every otherorgan, rebel at being overworked. This excessive evaporationis very uncomfortable, even though all the heat may be dis-sipated. By increasing convection and radiation the per-spiration is reduced and the losses are more uniformlydistributed, 87 Carrier Air Conditioning Company of America —

There can be no questionthat with a stationary high temperature a moderately lowhumidity is more comfortable than a high humidity. On theother hand, we are convinced that under certain conditionslow humidities and high temperatures are not so comfortableas high humidities and lower temperatures. Limitations of Cooling by Evaporation: Coolingby evaporation has perhaps its limitations like almost everythingelse, and we are not prepared to say where this limit lies, butfrom the figures quoted, it will be seen that some of the humid-ities are very high. One thing that undoubtedly has considerable to do withour comfort is the comparative condition/ We can be quitecomfortable in summer with conditions that would be uncom-fortable in winter, or vice versa.
