Abstract

An indoor unit of an air conditioner, includes a blower fan disposed within a casing; and a heat exchanger for heat-exchanging between refrigerant and air flowing by the blower fan, said heat exchanger connected to a refrigerant inlet pipe for introducing refrigerant and a refrigerant outlet pipe for discharging a refrigerant, wherein the refrigerant inlet pipe is connected to a side of the heat exchanger, where a flow velocity of the air passing through the heat exchanger is relatively high. Accordingly, efficiency of heat exchange between the indoor air and refrigerant can be improved, and thus cooling and heating efficiency of the indoor air is improved, thereby improving performance of the air conditioner. Also, by reducing the operation time of the air conditioner, power consumption can be reduced.
