Abstract: A heat exchanger includes a main heat exchanger configured to perform heat exchange between refrigerant and air and to define a first heat exchange surface and an auxiliary heat exchanger configured to perform heat exchange between refrigerant discharged from the main heat exchanger and air and to define a second heat exchange surface. The first heat exchange surface has an area larger than the area of the second heat exchange surface.
