Title: Indoor unit for air conditioning apparatus
Inventor: YOSHIKAWA MASAHARU
IPC: F24F1/00
Filed: 1987-05-27
Abstract: PURPOSE:To facilitate reduction of the thickness and the size of an indoor unit, by a method wherein, since arrangement of a plurality of heat exchangers and a direction in which a coolant flows are selected so that counterflow system heat exchanger is performed, efficient heat exchange effectively utilizing a vaporization compression type freezing cycle using a non-azeotropic mixing coolant is performed. CONSTITUTION:An air flow generated through rotation of a blower 5 is sucked through a suction port 2, and is discharged in a room through a discharge port 3 by means of a second heat exchanger 4, a first heat exchanger 4a, and a blower 5. Meanwhile the first and second heat exchangers 4a and 4b are arranged in series to an air flow, and an air flow and the flow of a coolant produce a counterflow on the whole of a heat exchanger equipped with the heat exchangers 4a and 4b. Thus, the first and second heat exchangers 4a and 4b perform an action equivalent to that of heat exchangers in 4 rows in a total to perform high efficiency heat exchange. By effectively utilizing characteristics of a vaporization compression type freezing cycle using a non-azeotropic mixing coolant and providing function equivalent to that of a multi- stage type heat exchanger, heat exchange can be effected with high efficiency, and the thickness of the whole of a heat exchange part can be reduced as the area of a heat exchanger is ensured to some extent.
