A drying facility for painting arranged for evaporation of liquid content present in an undried paint coating on a painting object placed in a treating chamber, the drying facility comprising heating means for heating air; and dehumidifying means for dehumidifying air; and arranged to feed the heated and dehumidified air to the treating chamber for the evaporation of liquid content; and as the dehumidifying means, there is provided an adsorption/desorption type dehumidifying device including an air-permeable adsorption rotor carrying an adsorptive agent, the rotor having a plurality of rotor portions along a rotational direction of the rotor, each rotor portion being brought, in alternation in association with rotation of the rotor, to an adsorption area through which dehumidification-subject air (A") is caused to flow and a desorption area through which desorbing air is caused to flow, characterized in that there are provided a dehumidification forward passage for guiding air withdrawn from the treating chamber as dehumidification-subject air (A") to the adsorption area and a dehumidification return passage for guiding dehumidified air (A") past through the adsorption area to the treating chamber; a desorption heat pump is provided for heating the desorbing air to be flown through the desorption area with utilizing, as a heat sink, dehumidified air (A") which has flown through the adsorption area and sent to the dehumidification return passage; and there is provided a sensible-heat heat exchanger configured to cool the dehumidification-subject air (A") present in the dehumidification forward passage through a heat exchange reaction between the dehumidified-subject air (A") present in the dehumidification forward passage and dehumidified air (A") present in the dehumidification return passage which has been cooled via absorption of its heat by the desorption heat pump so that heat contained in the dehumidification-subject air (A") present in the dehumidification forward passage is collected in the dehumidified air (A") present in the dehumidification return passage which has been cooled by absorption of its heat through the desorption heat pump. the drying facility comprising heating means for heating air; and dehumidifying means for dehumidifying air; and arranged to feed the heated and dehumidified air to the treating chamber for the evaporation of liquid content; and as the dehumidifying means, there is provided an adsorption/desorption type dehumidifying device including an air-permeable adsorption rotor carrying an adsorptive agent, the rotor having a plurality of rotor portions along a rotational direction of the rotor, each rotor portion being brought, in alternation in association with rotation of the rotor, to an adsorption area through which dehumidification-subject air (A") is caused to flow and a desorption area through which desorbing air is caused to flow, characterized in that there are provided a dehumidification forward passage for guiding air withdrawn from the treating chamber as dehumidification-subject air (A") to the adsorption area and a dehumidification return passage for guiding dehumidified air (A") past through the adsorption area to the treating chamber; a desorption heat pump is provided for heating the desorbing air to be flown through the desorption area with utilizing, as a heat sink, dehumidified air (A") which has flown through the adsorption area and sent to the dehumidification return passage; and there is provided a sensible-heat heat exchanger configured to cool the dehumidification-subject air (A") present in the dehumidification forward passage through a heat exchange reaction between the dehumidified-subject air (A") present in the dehumidification forward passage and dehumidified air (A") present in the dehumidification return passage which has been cooled via absorption of its heat by the desorption heat pump so that heat contained in the dehumidification-subject air (A") present in the dehumidification forward passage is collected in the dehumidified air (A") present in the dehumidification return passage which has been cooled by absorption of its heat through the desorption heat pump.
