4-3.Select comfortable summer design conditions (dry bulb and relative humidity) for a machines hop where people in light clothing (clo = 0.5) will be engaged in active work such as

hammering, sawing, and walking around (met = 1.8). Begin by selecting an operative temperature from Fig. 4-1. Assume that the me can radiant temperature is equal to the dry bulb temperature.A supervisor who is much less active than the other workers will occupy a space in the same environment. What is your suggestion for maintaining his or her comfort? choose the comfort temperature @50%rh based on Figure 4-1, then use Eq. (4-4a) b. operative temperature should be equal to air temperature if air temperature is as same as mean radiant temperature c. consider clothing impact for the supervisor
