Abstract
An automobile air conditioner has a refrigeration cycle composed of a compressor, condenser, liquid tank, orifice means and an evaporator, as well as mechanical parts such as a radiator and radiator fan associated with the condenser and a blower combined with the evaporator. The compressor is operatively connected to the automobile engine through a connecting means so as to be driven by the engine selectively in accordance with the temperature in the passenger's compartment. According to the invention, the compressor is driven when the automobile is being braked, even if the temperature in the compartment is lower than a set temperature, to make an efficient use of the kinetic energy possessed by the mass of the automobile. The cold energy generated during braking is suitably stored and is released into the passenger's compartment as desired.
