Document Type and Number:
Japanese Patent JPH08507123
Kind Code:
A
Abstract:
A heating and cooling device (10) generates a thermal difference using air and includes an impeller assembly (40) having a plurality of radial compartments (45), a channel (76) for air inlet, and an air outlet (56). Air drawn in through inlet channel (76) is compressed within compartment (45) by centrifugal force producing a pressure, temperature and density variation in the compartment (45) and a decrease in the entropy of the air. As the air is ejected through air outlet (56), work produced by the expansion is transferred to drive shaft (80) as torque, and entropy does not change more than the magnitude of the decrease in entropy during compression.
