Abstract
PURPOSE: To provide a room temperature controlling apparatus for use in an air conditioning system in which a plurality of indoor units are driven by a single outdoor unit, which is capable of finely and accurately controlling the temperature in each room independently.
CONSTITUTION: Each indoor unit, i.e., indoor heat exchanger is equipped with a valve means for supplying heating medium such as hot water from an outdoor unit to the indoor units. This valve means is designed such that its piston rod 20 is pushed out with expansion of thermally expansible substance of heat-sensitive driving element 17 when thermistor 22 having a positive charactistic is heated, and valve element 8 is pushed down by valve rod 14 against the force of spring 9, thereby opening the valve. Therefore, by suitably controlling the valve opening, quantity of heat discharged from the heat exchanger to the outside of room can be controlled and it enables to control room temperature. For the purpose, position of piston rod 20 is detected through detection of temperature of the driving element 17 by use of thermistor 24 having a negative characteristic, and energization of thermistor 22 is controlled to keep the piston rod 20 at a required position.
