Abstract

A heat pump is provided. The heat pump may include an outdoor heat exchanger that performs a heat exchange operation between refrigerant and outdoor air. The outdoor heat exchanger may include a refrigerant tube that guides refrigerant therethrough, and one or more fins coupled to the refrigerant tube. One face of each of the fins may be coated with a water repellent coating material and another face thereof may be coated with a hydrophilic coating material. An area coated with the water repellent coating material may be greater than an area coated with the hydrophilic coating material.
