ABSTRACT:
A temperature sensor, e.g. a thermistor (24, 37, 41, 46, 50', 57) is provided in a hollow space in cup-shaped shell (22, 36, 39, 42, 50, 54) of a size, e.g. 30 mm diameter and 15 mm depth, at a position of 1/3 height (i.e. 5 mm) of the depth from the bottom of the shell, the shell having wide opening (23, 33, 43, 47, 55) at its top part, and the temperature sensor is heated by feeding a controlled current to itself or to a heater provided at proximity thereto; the temperature sensor senses environmental condition in the similar manner to human sensation, taking account of air temperature, air flow and radiant heat from nearby matter such as wall or ceiling; thereby enabling comfortable air controlling.
