Title:
REFRIGERATION AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3953871
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration air conditioner capable of obtaining a desired refrigerant pressure without increasing the power of the entire compressor, and further improving the refrigerating effect.
SOLUTION: In this refrigeration air conditioner having a refrigerant pipe 5 for allowing a refrigerant of carbon dioxide to be successively circulated in a first compressor 1a, a first radiator 2a, an expanding mechanism 3a and a heat sink 4, and releasing the heat from the first radiator 2a in a supercritical state, a second compressor 1b is mounted in a refrigerant pipe 5 between the heat sink 4 and the first compressor 1a, and a rotating drive shaft 6 of the second compressor 1b and a rotating output shaft 6 of the expanding mechanism are linked. As the driving force of the second compressor 1b can be obtained from the power obtained in accompany with the refrigerant expanding action of the expanding mechanism 3a, the power of the first compressor 1a spent for raising the refrigerant pressure to a predetermined pressure can be reduced.
