Heat pumps of small size which use the centrifugal force (field) to provide extensive cooling. The invention includes a centrifuge which rotates about the shaft DA and in which there flows a gas accelerated by a propeller secured to the shaft DA. The gas travels through the circuit BCDOMNJ in pipes which are thermally insulated, except the levels C and MAN. At the level BC, it has the temperature t2. At the level C, it gives up heat energy to the external medium, and it passes to the temperature t1. Between C and D, it works against the centrifugal field (force) which cools it down to the temperature t1- DEG . Between D and O, it is propelled by the propeller secured to the shaft. At the level MN, it takes heat energy from the enclosure E, which raises its temperature. It then arrives at the level B at the temperature t2. The gas will take heat energy from the enclosure E until this enclosure is in thermal equilibrium with the temperature t1 - i DEG . <IMAGE>
