Abstract (en)

[origin: WO9953784A1] The invention concerns a thermodynamic device for regulating the heat of an object subjected to possible differential temperature, comprising at least one compressor (11) activated by the foot or another part of the body. It consists of two parts with different pressure levels connected by an expansion member (19) with vortex effect in a vortex tube for separating expanded compressed air into cold air and warm air. Another embodiment uses a Carnot cycle and another a solid/gas thermodynamic sorption device. The invention is applicable in particular to heating and cooling shoes.
