A desiccant air conditioner has a high energy efficiency due to the absence of excessive heat loss due to ventilation. In order to meet this requirement, the desiccant air conditioner is equipped with a honeycomb rotor wash-coated with agents having capabilities of absorptions of humidity, carbon dioxide and nitrogen, and this honeycomb rotor is divided into at least an absorption zone and a desorption zone. The air in a room is, after being passed through the absorption zone, fed back to the room, and the air which is passed through the desorption zone is exhausted into outside of the room. In this way, carbon dioxide and nitrogen in a room, the latter quantity being corresponded to that of the consumed oxygen in the room, are exhausted into outside of the room, allowing to exhaust carbon dioxide and at the same time to keep the oxygen density to within an allowed limit without the need of excessive ventilation.

1. A desiccant air conditioner comprising: a honeycomb rotor divided into at least an absorption zone and a desorption zone, the absorption zone having an inlet portion provided with a first absorbent that absorbs humidity and carbon dioxide, and an exit portion provided with a second absorbent that absorbs nitrogen, whereinair in a room is, after being passed through the inlet portion of the absorption zone and then the exit portion of the absorption zone, fed back to the room, andair which is passed through the desorption zone is exhausted into a space that is outside of the room and outside of the air conditioner. 2. The desiccant air conditioner according to claim 1, wherein a purge zone is provided, andthe air in the room is, after being passed through the purge zone, heated and passed through the desorption zone, then exhausted into a space that is outside of the room and outside of the air conditioner. 3. The desiccant air conditioner according to claim 1, wherein further air in a room is, after being passed through the absorption zone, passed through the desorption zone and exhausted into a space that is outside of the room and outside of the air conditioner. 4. The desiccant air conditioner of claim 1, wherein the first absorbent is an ionic exchange resin coated on the inlet portion, and the second absorbent is at least one zeolite selected from zeolite families of CaA, NaX, CaX, LiLSX and NaLSX coated on the exit portion. 5. A desiccant air conditioner comprising: a honeycomb rotor having a capability of at least humidity absorption or absorbing process; andanother honeycomb rotor having a capability of carbon dioxide absorption or absorbing process and a nitrogen absorption capability, whereinboth honeycomb rotors are divided into at least absorption zones and desorption zones,air in a room is, after being passed through the respective absorption zones, fed back to the room, andair which is passed through the respective desorption zones is exhausted into a space that is outside of the room and outside of the air conditioner. 6. The desiccant air conditioner according to claim 5, wherein further air in a room is, after being passed through the respective absorption zones, passed through the respective desorption zones and exhausted into outside of the room and outside of the air conditioner. 7. A desiccant air conditioner comprising: a honeycomb rotor divided into at least an absorption zone and a desorption zone, the absorption zone having an inlet portion provided with a first absorbent that absorbs humidity and carbon dioxide, and an exit portion provided with a second absorbent that absorbs nitrogen,the air conditioner configured to intake air of a room into the air conditioner and then pass the air through the inlet portion of the absorption zone and then the exit portion of the absorption zone, thereby causing the honeycomb rotor to absorb carbon dioxide and nitrogen of the air of the room,pass at least a portion of the air of the room having passed through the absorption zone back into the room, andpass air through the desorption zone, thereby causing the carbon dioxide and the nitrogen of the air of the room previously absorbed by the honeycomb rotor to be desorbed into the air passed through the desorption zone, and subsequently exhaust the air passed through the desorption zone into an outside space that is outside of the room and outside of the air conditioner. 8. The desiccant air conditioner of claim 7, configured to pass a first portion of the air of the room having passed through the absorption zone back into the room, andpass a second portion, of the air of a room having passed through the absorption zone, through the desorption zone and subsequently into the outside space, without passing the second portion into the room after passage of the second portion through the absorption zone and before passage of the second portion to the outside space. 9. The desiccant air conditioner of claim 7, configured to intake a second air from a space that is outside of the room and outside of the air conditioner, andpass the second air through the desorption zone and subsequently into the outside space, without passing the second air into the room after entry of the second air into the conditioner and before passage of the air into the outside space. 10. The desiccant air conditioner of claim 8, wherein the desiccant air conditioner further comprises a heater, andthe desiccant air conditioner is configured to pass the second portion of the air having passed through the absorption zone to the heater to be heated by the heater, before passing the second portion through the desorption zone. 11. The desiccant air conditioner of claim 7, wherein the first absorbent is an ionic exchange resin coated on the inlet portion, and the second absorbent is at least one zeolite selected from zeolite families of CaA, NaX, CaX, LiLSX and NaLSX coated on the exit portion. 12. The desiccant air conditioner of claim 10, wherein the first absorbent is an ionic exchange resin coated on the inlet portion, and the second absorbent is at least one zeolite selected from zeolite families of CaA, NaX, CaX, LiLSX and NaLSX coated on the exit portion.
