A dual super-cooling apparatus and an air-conditioner using the same are provided to prevent mass flow of refrigerant from being reduced by sufficiently super-cooling liquid refrigerant, which has been super-cooled in a first super cooling unit, through a second super-cooling unit. A dual super-cooling apparatus and an air-conditioner using the same comprises a super-cooling expansion unit(160), a first super-cooling unit(150) and a second super-cooling unit(170). The super-cooling expansion unit expands refrigerant condensed in a condenser(120) to generate cooling medium. The first super-cooling unit is connected to the condenser and the super cooing expansion unit to super cool liquid refrigerant condensed in the condenser into the cooling medium. The second super-cooling unit is connected to the first super-cooling unit and the super-cooling expansion unit to receive and super-cool the super cooled liquid refrigerant of the first super-cooling unit. |
