PURPOSE: An indoor ski structure is provided to enable a user to always enjoy skiing, snow board play, and sledge riding play free from weather restraints, and to maintain the temperature of the interior thereof at a low degree by use of an effective method. CONSTITUTION: The indoor ski structure comprises a snow removing device, a slope of a desired angle, and an air conditioning system of heat pump type having a cooling circuit and a heating circuit. Each circuit consists of a heat pump compressor(201), a switching valve, an exterior heat exchanger(211), a decompression device, and an interior heat exchanger(203,206), which are connected in series. In the interior heat exchanger of the cooling circuit, the compressed coolant flows toward the compressor after completing the heat exchange work. The interior heat exchanger for the heating circuit is designed into a double tube form, thus the compressed coolant is circulated in the inner tube of the interior heat exchanger, and a hot water is circulated in the outer tube thereof.
