Determine whether the following conditions are expected to be comfortable for light office work. Summer: air temperature = radiant temperature =23 degree C (73.4 degree F), relative humidity = 60 percent. Summer: air temperature = 22 degree C (71.6 degree F) and radiant temperature = 28 degree C (82.4 degree F) (assume that the convective and radiative heat transfer coefficients are equal), relative humidity = 30 percent. Winter: air temperature = radiant temperature = 20 degree C (68 degree F), relative humidity = 30 percent.

Solution

for summer the cmfortable condition for light office work are

temp between 20-24 C and RH 60%

this condition is met by option \'a\' and not by option \'b\'

also for winter the RH should be 50% which is not there in option \'c\' and hence it is not comfortable condition
