Air conditioner

Abstract

Abstract PURPOSE:To average the speed distribution of air passing through a heat exchanger and increase a heat exchanging efficiency by a method wherein the number of rows of pupes of the heat exchanger for an indoor unit is increased at a place near a fan but it is decreased at the place far from the fan. CONSTITUTION:The heat exchanger 13 consists of an upper heat exchanger 13a, located at a side near the cross-flow fan 15 and equipped with double rows piping holes 14, and the lower heat exchanger 13b, located at the place far from the cross-flow fan 15 and equipped with single row piping holes 14, while these upper and lower heat exchangers 13a, 13b are connected by both side plates so as to function as one unit of heat exchanger 13. Upon operation, the air speed is faster at the place near the fan 15 and the air passes through the upper heat exchanger 13a into the direction shown by an arrow sign A. At the place near the arrow sign B, it is far from the fan 15 but the piping holes 14 are arranged in single row, therefore, tbe passing resistance of the air is small and the air speed distributions with respect to all piping holes may be averaged substantially.
