PURPOSE:To secure space for a driver's room such as construction machines in an air conditioning device for an industrial car by arranging the air conditioning unit on the side wall of the driver's room or at the outside of a rear wall and collectively arranging air conditioning functional components at the inside of an atmospheric intake port. CONSTITUTION:An sir conditioning unit 3 arranges an air blower 6, evaporator 7, heater core 8, etc. in a case 9 and provides an atmospheric intake port 10 and an inside air intake port 11 on both sides of an aperture section 13 with an atmospheric switching damper 14 on the wall 12 of the case. In addition, an atmospheric filter 5 and an inside air filter 17 are mounted at the atmospheric intake port 10 and the side wall aperture section 16 of a driver's room 1 so as to be attached and detached, respectively. A motor 6a, fan 6b, resistor 6c, expansion valve 18, water valve 19, pressure switches 20 and 21, thermostat 26, relay 27, etc. are collectively arranged in the inner part of this atmospheric intake port 10. As a result, a compact air conditioning device with good reconditioning can be obtained without narrowing the space of the driver's room such as construction machines. |
