As shown in Figure 1, the temperature and humidity regulation system of present invention process wind comprises: the first evaporimeter 1, second evaporimeter 2, desiccant wheel 3, second condenser 4, first condenser 5, regeneration blower fan 6, process air blower 7, cooling blower 8, first compressor 9, first throttle device 10, second compressor 11, second throttling arrangement 12, first refrigeration pipe 13, second refrigeration pipe 14, process air chamber 20, regeneration air room 30 and cooling-air room 40.The dehumidifying side 31 of the first evaporimeter 1, second evaporimeter 2, desiccant wheel 3 and process air blower 7 are arranged in process air chamber 20 successively, regeneration side 32 and second condenser 4 of regeneration blower fan 6, desiccant wheel 3 are arranged in regeneration air room 30 successively, and the first condenser 5 and cooling blower 8 are arranged in cooling-air room 40 successively; First evaporimeter 1, first compressor 9, first condenser 5 and first throttle device 10 connect and compose the first closed compression refrigerating system successively by the first refrigeration pipe 13, and the second evaporimeter 2, second throttling arrangement 12, second condenser 4 and the second compressor 11 connect and compose the second closed compression refrigerating system successively by the second refrigeration pipe 14.
The rotating speed of desiccant wheel 3 and regeneration blower fan 6 is adjustable.
The temperature and humidity regulation method of present invention process wind is specially: when the enthalpy of process air A1 is higher (higher than a certain setting value, as 70kJ/kg) time as summer, the first compressor 9, second compressor 11, cooling blower 8, process blower fan 9 and regeneration blower fan 6 all work.Process air A1 is cooled and dehumidifying by the first evaporimeter 1, then is further cooled by the second evaporimeter 2 and is dehumidified, more dehumidified by the dehumidifying side 31 of desiccant wheel 3; Regeneration air A2 is heated by the second condenser 4, then is regenerated by 32 pairs, the regeneration side desiccant wheel 3 of desiccant wheel 3, and cooling-air A3 is cooled it by the second condenser 5,
