4. the air-treatment method of air processor according to claim 3; It is characterized in that: when temperature, the humidity of outdoor new wind are lower than indoor return air temperature and humidity, in air handling process, indoor return air will no longer be regulated air-valve (1) by return air and get into air processor; But take brand-new wind operation; After new wind was regulated air-valve (4) entering air processor through new wind, air carried out heat exchange with the high temperature chilled water in pyrometric scale cooler (5), and the temperature of air reduces; Air is divided into two-way after pyrometric scale cooler (5) comes out; One the tunnel gets into cryometer cooler (7), in cryometer cooler (7), carries out heat exchange with cryogenic freezing water, and air is realized cooling and dehumidifying; Other one the tunnel; Air is regulated air-valve (9) back through bypass and is mixed with the air that comes out from cryometer cooler (7); Pass through heater (10), humidifier (11) then, send into indoor through the air outlet (13) of air processor after being sucked, pressurize by blower fan (12).
5. the air-treatment method of air processor according to claim 3; It is characterized in that: when temperature, the humidity that detects outdoor new wind when control-driven system (19) is lower than indoor return air temperature and humidity, control-driven system (19) will be closed return air and regulated air-valve (2), only leave very little air mass flow this moment; Guarantee first temperature sensor (14); First humidity sensor (15), the measurement of gas concentration lwevel sensor (16) is opened new wind and is regulated air-valve (4); Take brand-new wind operation; Same control-driven system (19) is according to the temperature of the measured indoor return air of first temperature sensor (14), and control high-temperature water flow control valve (6) is regulated the water yield that gets into pyrometric scale cooler (5) or sent the adjustment signal of high-temperature water by control-driven system (19) to central control system; Change the high temperature chilled water temperature, thereby guarantee that indoor temperature reaches design temperature; Control-driven system (19) is according to the humidity of the measured indoor return air of first humidity sensor (15); The aperture that the control bypass is regulated air-valve (9); Change the air mass flow that gets into cryometer cooler (7); Realize cryometer cooler (7) air by the control of moisture removal, thereby realize the adjusting of indoor humidity.
