To provide a dew proofing device for a desiccant air conditioner for preventing dew condensation in a sensible-heat heat exchanger in ventilating operation.
This desiccant air conditioner comprises a dew-proofing control means for executing either an exhausting operation where only a second blower 11 is operated while stopping a first blower 10, or a purging operation for operating the first and second blowers 10, 11 and operating a latent heat rotor 15 and a purge heater 14, when a differential temperature (evaluated differential temperature value) obtained by subtracting an inside air temperature Tin from an outside air dew-point temperature Tdewout is over a prescribed threshold value in a state of the ventilating operation in which the latent heat rotor 15 and the regenerative heater 13 are stopped and the first and second blowers 10, 11 are operated.
