The design of thermal comfort environment in the cab of construction machinery or farm machinery with air-conditioning system is much different from one in the house or office, because the ratio of an operator space to the cab volume is much larger than that of the other cases and he must operate the machine looking outside from a small enclosed cab. In this paper, in order to improve thermal comfort of an operator in the cab, two types of real construction machinery were provided with heater or cooler and these thermal environments were analyzed respectively. From these tests, it was made clear that the thermal distribution in each cab was not uniform even in case that air-conditioning capacity was sufficient. So, it seems that uneven thermal distribution gives the operator discomfort.
