PURPOSE: A heating device without an outdoor unit is provided to facilitate to install by integrating a first heat exchanger, a capillary tube, and a second heat exchanger to a casing which is installed the inside. CONSTITUTION: A heating device without an outdoor unit comprises a first heat exchanger(150), a second heat exchanger(130) and capillary tube unit(170). The first heat exchanger performs the role of condenser and compressor(110). The second heat exchanger performs the role of an auxiliary condenser or evaporator. The capillary tube unit performs the role of an expansion valve. Refrigerant performs a heating operation by circulating the first heat exchanger, second heat exchanger, and capillary tube unit. One side of the compressor is equipped with a valve(200) in order to flow the refrigerant in the first heat exchanger and a liquid receiver(250). |
