The opening degrees of the first adjustment valve 43 in the refrigeration cycle Ccc (cooling side) and the second adjustment valve 46 in the second refrigeration cycle Chc (heating side) are set.

  On the other hand, when the operation of the temperature adjusting device M starts, the temperature of the air A blown out from the air outlet 11 ue is detected by the temperature sensor 20 and applied to the controller 19. Thereby, the controller 19 performs feedback control of the first refrigeration cycle Ccc and the second refrigeration cycle Chc including the compressor 5 so that the detected temperature of the applied air A becomes a preset target temperature. At this time, the first regulating valve 43 and the second regulating valve 46 are also controlled until the target temperature is reached after the operation is started. Thus, the diversion ratio is set to an optimum diversion ratio according to a preset program.
