a second channel formed in the housing such that second air passes through the second channel;
a desiccant rotor rotatably installed in the housing while being disposed over the first and second channels, so that the desiccant rotor is dried by the first air passing therethrough and absorbs moisture from the second air passing therethrough;
a heating unit disposed upstream of the desiccant rotor so as to be closer to an introduction side of the first air in the first channel, the heating unit serving to heat the first air passing therethrough;
a cooling unit disposed downstream of the desiccant rotor so as to be closer to a discharge side of the second air in the second channel, the cooling unit serving to selectively cool the second air passing therethrough;
a refrigerant circulation unit comprising a compressor, a first heat exchanger, a second heat exchanger, and a four-way valve, the first heat exchanger being disposed downstream of the cooling unit so as to be closer to the discharge side of the second air in the second channel, a refrigerant being circulated in the refrigerant circulation unit in order of the compressor, the first heat exchanger, the second heat exchanger, and the compressor or vice versa, according to control of the four-way valve; and
a water circulation pipe in which water is circulated, the water circulation pipe being connected to the second heat exchanger such that the water circulating therein exchanges heat with the refrigerant in the second heat exchanger.

2. A hybrid heat pump apparatus comprising:
a housing;
a first channel formed in the housing such that first air passes through the first channel;
a second channel formed in the housing such that second air passes through the second channel;
