Abstract: An air conditioning system is disclosed which includes a compressor, a condenser, an evaporator, a first fan for the condenser, and a second fan for the evaporator. A case which encloses at least the compressor, the condenser, the evaporator, the first fan and the second fan comprises an inner housing, and an outer housing which encloses the inner housing. Exposed portions which project on the outer surface of the outer housing and the outer housing are made of insulating materials.

Abstract: An air conditioning system is disclosed which includes a compressor, a condenser, an evaporator, a first fan for the condenser, a second fan for the evaporator, and an oil hydraulic motor for the driving compressor. A rotation transmitting mechanism couples the first and second fans with the oil hydraulic motor to transmit rotational force from the oil hydraulic motor to the first and second fans. A hand operating mechanism is connected through a coupling to an air mix damper which is disposed between the second fan and the evaporator. The hand operating mechanism is operated to control the proportion of the air which passes through the evaporator to the air which does not pass through the evaporator.
