A spot cooling system using the convective cooling effect of an air stream is known to beeffective by its smothering intensive hot environment, supplying comfort sense and utilizingenergy efficiently. However, its study on the interaction with human body or product itself isuncommon, showing that the spot cooling system intrinsically contains the possibility ofdraught because of its short emitting distance from the object, low air temperature, high airstream velocity and its direct local contact to human body. Therefore, the object of this studyis to clarify the effects of the spot cooling system on the human body with detailed partsaccording to the room temperature, emitting air temperature to supply a more successfulpersonal air conditioning system. The experiment was conducted in winter. The subjects (fouryoung females) were exposed to the following conditions: combinations of air temperatures(Ta = 27, 30C), discharge temperature (Tdc = 13C) and relative humidity (RH = 50%).
