PROBLEM TO BE SOLVED: To provide a cooling and heating device successfully performing cooling operation and heat pump operation while reducing cost. SOLUTION: The cooling and heating device is provided with: a cooling route 20 constituted by interconnecting a compressor 21, a condenser 22, a capillary tube 23 and an evaporator 24; a heating route 30 constituted to condense a refrigerant compressed by the compressor 21 by an interior heat exchanger 31 and send the refrigerant to the capillary tube 23; and a valve unit 40 allowing the refrigerant compressed by the compressor 21 to flow in the condenser 22 during cooling operation and to flow in the interior heat exchanger 31 during heat pump operation. During cooling operation, the refrigerant passed through the condenser 22 is allowed to flow in the interior heat exchanger 31, while, during heat pump operation, the refrigerant passed through the interior heat exchanger 31 is allowed to flow in the condenser 22, so as to make constant the volume where the high pressure refrigerant is made to flow.
