Abstract
An automotive air conditioner uses a non-azeotropic mix-type refrigerant of a higher boiling point refrigerant and a lower boiling point refrigerant. The automotive air conditioner changes its cooling capacity by varying the proportion of the lower boiling point refrigerant and the higher boiling point refrigerant. In order to madulate the proportion of the refrigerant, the present heat exchanger employs a rectifying means and a cooling means. The cooling means introduces the refrigerant circulating in the refrigerant circuit as the cooling medium when the air conditioner is not required high cooling capacity, so that lower boiling point refrigerant is separated and is stucked within the cooling means within a short while.
