PURPOSE: To bring the speed of condenser air blowing means into direct proportion to a prime mover and hereby select the speed of evaporator air blowing means by constructing an air blowing apparatus such that when an electric clutch is switched on, the evaporator air blowing means is driven at a higher speed than the condenser air blowing means, while when the same is switched off, the evaporator air blowing means is driven at the same speed as the condenser air blowing means. CONSTITUTION: There are provided a third pulley 48 fixed to an outer lace 47 of a one-way clutch 45 and coupled with a condenser blower 26, and a fourth pulley 64 fixed to a second shaft 24. There is provided a first belt 52 mutually communicating first and third pulleys 46, 48 for driving a condensation blower 26 at a speed proportional to a prime mover 12. There is further provided a second belt 66 mutually communicating second and fourth pulleys 56, 64. When an electric clutch 54n is turned on, a second shaft 24 and an evaporator blower 30 are drive at a higher speed than the condensation blower 26, and when the same is turned off, the evaporator blower 30 is driven at the same speed as that of the condenser blower 26 through the one-way clutch 45. |
