PURPOSE:To enable ventilation simultaneously with cold air or hot air by providing a cooler and a heater at both ends of a boiling-condensing type heat exchanger penetrating through upper and lower stage air passages. CONSTITUTION:Within a case 4 mounted on a wall 1, there are formed upper and lower air passages 7A and 7B by a partition wall 5 and shutters 19A and 19B, and a boiling-condensing type heat exchanger 11 penetrates through the partition wall 5. A manifold 13A containing a cooler 14 is integrally formed on the upper end of a closed vessel 11A and a manifold 13B containing a heater 14B is integrally formed on the lower end thereof, and low-temperature and high-temperature mediums are supplied. Fans 10A and 10B are installed in the inside 2 of the room of the heat exchanger 11. Two pieces of shutters 19A and 19B are aligned in the horizontal direction, and move independently to communicate or interrupt with or from chambers 18A and 18B between the heat exchanger 11 and ventilation shutters 9A and 9B to adjust the temperature of the blast within the chamber. |
