Air conditioner for railway vehicles

An air conditioner having an indoor unit placed in a room to be heated or cooled, and a draft directing apparatus, such as a vertically tilting louver, which can assume a first position directing an outlet draft toward the location where a user is normally positioned, e.g., downward, and a wecond position directing the output draft away from said location, e.g., upward. The draft directing apparatus is controlled to assume the first position and the second position alternately, in such a manner that the proportion of the time for which the draft directing apparatus is in the first position is adjusted in accordance with the detected temperature of the draft. This adjusts the proportion of the time the draft is directed toward the user, and it is therefore possible to adjust the stimulation affecting the user.

Air conditioner

A heater comprising a heater body containing a heating source; an air blower for forcibly blowing off heated air from the heater body into a room, the heated air being produced by heat-exchanging with the heating source; a first temperature detection element for detecting a temperature at an upper level in the room; a second temperature detection element for detecting a temperature at a lower level in the room; a sensation input means for enabling a user to input his or her sensation corresponding to an actual room temperature; means for determining heating capability of the heating source based on the difference between the temperature detected by the first temperature detection element and a first set temperature; means for changing the outlet area and/or the air volume of the heated air based on the difference between the temperature detected by the second temperature detection element and a second set temperature lower than the first set temperature to determine the blow-off speed and/or the air volume of the heated air; and a control means for changing the first set temperature and the second set temperature based on the input given through the sensation input means.
