The outside air 10 is commonly known as air. Furthermore, the incineration equipment 60 is any one of a direct-fired incinerator (TO), a catalytic incinerator (not shown) or a regenerative thermal incinerator (RTO) (not shown).

In addition, the at least one first temperature device 23 is any one or a combination of a pre-cooling coil 231 and a pre-heating coil 232 (such as Figure 2 As shown in FIG. 1 , the precooling coil 231 is fed with either cooling water or ice water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. The preheating coil 232 is fed with either hot water or steam to transfer heat energy to the outside air 10 to increase its temperature. Furthermore, the at least one first temperature device 23 may also be any one or a combination of a precooler 233 and a preheater 234 (such as Figure 1 As shown), the precooler 233 is any one of a shell and tube cooler, a fin tube cooler or a plate heat exchanger cooler, and the preheater 234 is any one of an electric heater, a gas heater, a thermal oil heater, and a hot water heater.

[0053] In addition, the at least one water washing device 24 is a washing humidifier, which is mainly composed of at least one pressure pump, at least one nozzle, at least one water supply valve, at least one drain valve, and at least one pipeline (not shown). When the outside air 10 passes through the washing humidifier, water molecules will fully absorb the heat in the air and vaporize and evaporate, so that the humidity of the outside air 10 increases to form humidified air. In addition, the at least one second temperature device 26 is any one or a combination of a re-cooling coil 261 and a re-heating coil 262 (not shown) (such as Figure 2As shown in the figure, the above-mentioned re-cooling coil 261 is supplied with either cooling water or ice water to cool the hot air in the outside air 10 into liquid, thereby effectively reducing the air temperature. And the above-mentioned reheating coil 262 (not shown) is supplied with either hot water or steam to transfer heat energy to the outside air 10 to increase its temperature. Furthermore, the at least one second temperature device 26 can also be any one or a combination of the recooler 263 and the reheater 264 (such as Figure 1 As shown), the recooler 263 is any one of a shell and tube cooler, a fin tube cooler or a plate heat exchanger cooler, and the reheater 264 is any one of an electric heater, a gas heater, a thermal oil heater, and a hot water heater.

The drawings of the utility model show that the dehumidification wheel 25 is located in the middle of the second temperature device 26, but the drawings are not limited to the figures. The 3 / 4 area of ​​the dehumidification wheel 25 is the processing area 251, and when the outside air (Outside Air) 10 to be processed passes through the processing area 251, the moisture in the outside air (Outside Air) 10 is absorbed by the desiccant attached to the special fiber, and becomes low-humidity dry air, and is blown out from the other end of the processing area 251, so that the outside air (Outside Air) 10 after passing through the at least one washing device 24 can be adjusted to the absolute humidity of the outside air (Outside Air) 10 to meet the requirements through condensation dehumidification.

[0055] In addition, the first heat exchanger 30 provides a heat source to the regeneration zone 252 (such as Figure 1 and Figure 2 As shown in FIG. 2 ), the temperature of the heat source exceeds 100°C and enters the remaining 1 / 4 of the dehumidification wheel 25, that is, the regeneration zone 252, in the opposite direction. The heat source slowly enters the regeneration zone 252 to increase the temperature of the desiccant attached to the special fiber, so that the moisture contained in the desiccant attached to the special fiber is vaporized and taken out of the desiccant wheel 25, so that the desiccant attached to the special fiber can restore the moisture absorption function, that is, the desiccant is regenerated. In addition, when the desiccant wheel 25 rotates slowly, the desiccant attached to the special fiber of the desiccant wheel 25 undergoes moisture absorption and regeneration processes simultaneously, so the desiccant wheel 25 can ensure continuous and stable output of dry air.

[0056] In addition, at least one second filter device 27 is disposed in the housing 21 of the outdoor air conditioning system 20. The at least one second filter device 27 is located at the rear section of the housing 21 (eg Figure 1 and Figure 2 As shown in the figure, the outside air 10 after dehumidification and adsorption in the treatment area 251 of the dehumidification wheel 25 enters the at least one second filter device 27 for filtration, and the at least one second filter device 27 is any one or a combination of a high-efficiency particulate air filter (HEPA) or an ultra-low penetration filter (ULPA).

It is the most effective filtering medium for pollutants such as smoke, dust and bacteria, and its material is mainly ultra-fine glass fiber paper or composite filter paper.
