Abstract
An air conditioning system comprises: a motor (5, 69); a speed increasing mechanism (7) connected to the motor to increase revolution speed of the motor; an air compressor (3) driven by the motor through the speed increasing mechanism at high speed to produce a high-temperature pressurized air; a cooler (11) for cooling the high-temperature pressurized air; and a turbine (9) for further cooling the pressurized air cooled by the cooler on the basis of adiabatic expansion. The rotational force of the turbine is feed-backed to the motor and the air compressor. In the air conditioning system thus constructed, since the air compressor (3) is driven by the motor (5, 69) through the speed increasing mechanism (7) in particular, it is possible to increase the pressure ratio of the air compressor and the air conditioning capacity, without increasing the size and weight of the air conditioning system.
