PROBLEM TO BE SOLVED: To provide an air conditioning device for a construction and agricultural machine capable of preventing a front glass from being fogged even when blowoff air has temperature distribution.SOLUTION: An air conditioning device for a construction and agricultural machine comprises: an air conditioning case 11 which is mounted on a ceiling 3 of a cabin 2 and forms an air passage where air flows from a rear section to a front section; an evaporator 13 which is arranged inside the air conditioning case 11 and cools the air; a heater core 14 which heats the air passing through the evaporator 13; a bypass passage 15 which allows the air passing through the evaporator 13 to bypass the heater core 14; an air mixing door 16 which adjusts a merge ratio of the heated air heated by the heater core 14 to the cooled air passing through the bypass passage 15; and an outlet 5 which is installed on the ceiling 3 at a side of a front glass 4 of the cabin 2 and blows out the air, where the heated air and the cooled air are merged, toward a lower section. The heater core 14 is arranged on an upper side of the bypass passage 15. |
