PURPOSE:To adjust room temperature correctly by a method wherein a first chamber, shielded from hot air by a hot air shielding plate extended from a heat exchanger, is provided and second chamber, communicated with the first chamber, is provided with an opening as well as a temperature sensor. CONSTITUTION:Air is sucked by a fan motor 2 from the opening 19 of a pipe line cover 18 in addition to a suction port 1 and is sent toward the opening 7 of a fan casing 3 through the attaching part of a thermistor 12, the opening 21 of the piping cover 18, the opening 20 of a front plate 9, the hot air shielding plate 11 and the left side of the heat exchanger 5. Accordingly, the ambient temperature of the circumstance of the thermistor 12 increases so as to follow the room temperature and when the thermistor 12 has detected that the ambient temperature has arrived at a set temperature, the blow of hot air is stopped. Thereafter, an airstream, same as the case in which a fan is rotating, is generated by a natural draft effect at this time and the ambient temperature around the thermistor 12 is decreased so as to follow the room temperature, since the heat exchanger, through which high temperature water is flowing, is placed above the attaching part of the thermistor 12 and the suction port 1 is opened above the heat exchanger 5. |
