A cooling system for cooling units of furniture adapted for supporting the human body, and for car seats, steering wheels and arm rests, includes two main components. A closed loop air conditioning subsystem has a first motor which drives a compressor in which a refrigerant fluid is compressed. The compressed fluid is passed into a condenser where the compressed fluid is cooled by dissipating its heat into the environment, and from where the compressed fluid is released through an expansion valve into an evaporator. The evaporator becomes cool due to expansion of the refrigerant fluid into a gas and consequent absorption of heat from the evaporator's body and immediate environment. The refrigerant gas is returned from the evaporator into the compressor. The second main component of the invention is a subsystem where a working fluid is in heat exchange relationship with the evaporator of the first system whereby the working fluid is cooled in the evaporator and is thereafter sent by a pump or fan, driven by a suitable motor, into cooling members, such as cooling coils incorporated within the seat or other item of furniture (or related item) which is cooled directly.
