The specific embodiment
As shown in Figure 1, the utlity model has the fresh air processor of divergence type twin-stage surface cooler, in shell body 1, be provided with two two-stage surface coolers independent of each other, promptly all be provided with refrigerant import and refrigerant exit on first surface cooler 5 and second surface cooler, 6, the first surface coolers 5 and second surface cooler 6.Direction along air flows is provided with fresh inlet 2 and air outlet 8 at the two ends of shell body 1.In shell body 1, between fresh inlet 2 and air outlet 8, be arranged in order and be provided with screen pack 4, first surface cooler 5, second surface cooler 6 and blower fan 7.
The utility model also can be provided with return air inlet 3 further as shown in Figure 2 before screen pack 4 so that new wind and return air is through mixed before the screen pack 4, newly wind with carry out heat exchange with surface cooler again after return air mixes.
Use the method for air processing machine fresh air processor processing air of the present utility model as follows:
Open the blower fan of air processing machine, the new wind of coming in from fresh inlet 2 (or the air by fresh inlet 2 new wind of coming in and the return air of coming in from return air inlet 3 after mixed) filters through screen pack 4 earlier, then through first surface cooler 5.Carry high temperature refrigerant by the refrigerant import 10 of the first cold water station, first surface cooler 5 to first surface cooler 5 simultaneously, air is carried out the precooling cool-down dehumidification.The refrigerant that first surface cooler is 5 li is generally 15 ℃ or above high temperature cold water (preferred 15～18 ℃ high temperature cold water).High temperature refrigerant carries out heat exchange with to the air precooling cool-down dehumidification with air in first surface cooler 5, the temperature of high temperature refrigerant rises 3～5 ℃ after the heat exchange, and back high temperature refrigerant returns the first cold water station by the refrigerant exit 9 of first surface cooler 5 and carries out recycling.
The utility model utilizes high temperature cold water to carry out precooling, on the one hand is because this fresh air processor is to use with the temperature control tip engages of humiture autonomous control system, can directly utilize existing high temperature cold water and does not need to establish in addition low-temperature receiver; Utilize the high temperature cold water precooling on the other hand, can improve the efficient of humiture autonomous control system.
Enter second surface cooler 6 again through the air behind first surface cooler, the 5 precooling cool-down dehumidifications and carry out dehumidification by condensation.Low temperature refrigerant in second surface cooler 6 is supplied by the second cold water station, and the low temperature refrigerant enters second surface cooler 6 via refrigerant import 12.The refrigerant that second surface cooler is 6 li is generally 7 ℃ or following low-temperature cold water (preferred 2～7 ℃ low-temperature cold water).The air of low temperature refrigerant in second surface cooler 6 and behind first surface cooler, 5 precooling cool-down dehumidifications carries out heat exchange and realizes further cool-down dehumidification, the temperature of low temperature refrigerant rises 5～10 ℃ after the heat exchange, and the low temperature refrigerant returns the second cold water station through the refrigerant exit 11 of second surface cooler 6 afterwards.Simultaneously, the air after second surface cooler 6 is handled is sent from air outlet 8 through blower fan 7.
Air is being carried out in the processing procedure, can control the air-out water capacity by the control of the electric control valve on the refrigerant pipe of regulating first surface cooler 5 and second surface cooler 6 aperture and reach setting value.The air-out water capacity is detected by the air-out water capacity sensor 15 that is installed on the air outlet place.
The control method of air-out water capacity is specifically: the air-out water capacity of controlling the utility model fresh air processor by the control of the electric control valve on the refrigerant pipe of regulating first surface cooler 5 and second surface cooler 6 aperture: when air-out water capacity measured value during greater than setting value, drive the electric control valve on the refrigerant pipe of big first surface cooler 5 and second surface cooler 6, it is constant to keep current valve position when the air-out water capacity reaches setting value; When air-out water capacity measured value less than when setting value, turn down the electric control valve on the refrigerant pipe of first surface cooler 5 and second surface cooler 6, it is constant then to keep current valve position when the air-out water capacity reaches setting value.Two-stage surface cooler control order is as follows:
When air-out water capacity measured value greater than when setting value, control the air-out water capacity by the motor-driven valve 13 on the refrigerant pipe of opening big first surface cooler 5 earlier and reach setting value; If air-out water capacity measured value is still greater than setting value during the valve wide open of motor-driven valve 13 on the refrigerant pipe of first surface cooler 5, then opens and regulate motor-driven valve 14 on the refrigerant pipe of second surface cooler 6 again and control the air-out water capacity and reach setting value;
When air-out water capacity measured value less than when setting value, control the air-out water capacity by motor-driven valve 14 apertures on the refrigerant pipe of turning second surface cooler 6 down earlier and reach setting value; If the motor-driven valve 14 on the refrigerant pipe of second surface cooler 6 cuts out back air-out water capacity measured value still less than setting value, then by motor-driven valve 13 apertures on the refrigerant pipe of regulating first surface cooler 5 the air-out water capacity is controlled to reach setting value again.
