First order heat-exchanger rig 7 or second level heat-exchanger rig 8 use coil exchanger or finned heat exchanger.Humidifier
2 be wet-membrane humidifier.
Embodiment 2：
As shown in figure 1, the present embodiment provides a kind of airhandling equipment, the airhandling equipment includes embodiment 1
Water system, airhandling equipment using Fresh air handing unit, first order heat-exchanger rig or second level heat-exchanger rig use wing
Plate heat interchanger, humidifier use wet-membrane humidifier.
Heat-exchanger rig is cuboid, is divided into two layers up and down, centre is a metal material dividing plate, and dividing plate left side central portion has a leakage
Mouthful, two layers up and down of connection.Heat-exchanger rig is arranged on the supply channel of wet-membrane humidifier, and the device is connected to air-treatment simultaneously
Equipment supplies water return pipeline, and the A mouths of described device are wet-membrane humidifier water supply import, and B mouths are wet-membrane humidifier service water outlet,
Supply water from A mouths enter, full of air conditioning hot in whole heat-exchanger rig, with heat exchanger in heat-exchanger rig for backwater two-stage heat exchange after from
B mouths go out heat-exchanger rig.The CD mouths of the device are located at left and right sides of heat-exchanger rig top, and EF is located at heat-exchanger rig bottom or so two
Side, the first heat-exchanger rig and the second heat-exchanger rig are corresponded to respectively.From D mouths enter heat-exchanger rig, C mouths go out, air conditioning hot supplies water backwater
From F mouths enter heat-exchanger rig, E mouths go out subsequently into airhandling equipment.
Wet-membrane humidifier supplies water enters the first heat-exchanger rig by A mouths, is changed on device top and the backwater in CD segment pipes
Heat, it is the second heat-exchanger rig to enter heat-exchanger rig bottom by dividing plate 9 after heat exchange, is then supplied with the air conditioning hot in EF segment pipes
Water is exchanged heat, and by exchanging heat twice, humidifier supply water temperature can be improved to 40 DEG C, then from B mouths go out heat-exchanger rig enter it is wet
Film humidifier.
In NORTHWEST CHINA area winter, outside air temperature is relatively low and dries, it is assumed that airhandling equipment is Fresh air handling units, outdoor new
After wind enters Fresh air handling units filtering, constant humidity heating is carried out in heating dish pipeline section, now temperature is up to 30 DEG C, subsequently into wet film plus
Wet device carries out equal-enthalpy humidifying, and water drenching is generally running water (10 DEG C or so), because water drenching temperature is relatively low, humidification amount now occurs
The situation of very little.
Air conditioning hot is usually 60/50 DEG C for backwater, and by wet-membrane humidifier water system, wet-membrane humidifier supplies water and changed
Thermal first order heat-exchanger rig by air conditioning hot backwater is preheated to 30 DEG C or so for the first time, subsequently into preheating device bottom,
In the second level, heat-exchanger rig is supplied water by air conditioning hot be preheated to 40 DEG C for the second time.If the saturation efficiency of wet-membrane humidifier is
80%, 36.3% can be improved using the humidification efficiency of 40 DEG C of water drenchings and 10 DEG C of water drenching wet-membrane humidifier, air outlet slit state
Temperature rise is 4 DEG C.
Counties of North-west Five area, it is a kind of system for saving and using using evaporation cooling technique due to the particularity of weather conditions
Refrigeration technique, and wet-membrane humidifier is a kind of devaporizer in itself, now directly carries out constant enthalpy to air using wet-membrane humidifier
Humidification, by the precooling of air conditioner cold water backwater (12 DEG C or so), water drenching temperature is reduced to 14 DEG C or so by 20 DEG C, to the drop of air
Warm humidifying effect becomes apparent, and while a part of surface cooler load is shared, saves investment and operating cost.
