User's use space is sent into wind channel 16.
Fresh air bypass component 2 includes second shell 102, fresh air channel；Fresh air channel is arranged in second shell 102.
Air-treatment unit 100 further includes the new air-valve 103 that the first air mixing channel 11 is connected to or is disconnected with fresh air channel；
Air-treatment unit 100 further includes the mixer selector valve 104 that the second air mixing channel 13 is connected to or is disconnected with fresh air channel.
Then air in first air mixing channel 11 passes through 13 quilt of the second air mixing channel by 12 cool-down dehumidification of surface air cooler
Heating device 14 heats, and is humidified after the completion of heating by humidifier 15, finally uses via the feeding user of air-supply passage 16 empty
Between, to achieve the purpose that user's use space is made to keep constant temperature and humidity state, meet the requirement of user.Fresh air bypass component 2
The fresh air filled into is mixed into constant temperature and humidity component 1 with the return air of the first air mixing channel 11 by new air-valve 103 or fresh air bypass
The fresh air that component 2 fills into is mixed into constant temperature and humidity component 1 with the return air of the second air mixing channel 13 by mixer selector valve 104.
In above-mentioned air handling process, due to the air that fresh air is a high temperature and humidity, do not pass through surface air cooler 12
The process of reducing temperature and humidity, therefore refrigeration duty provided by the surface air cooler 12 of constant temperature and humidity component 1 can be reduced；It is permanent in entire constant temperature
In wet component 1, the heat and water capacity of fresh air are neutralized by the return air of reducing temperature and humidity, are reduced in constant temperature and humidity component 1
The heat investment of heating device 14 and the humidification amount of humidifier 15 are put into.Fresh air treatment system mainly utilizes the heat of fresh air
Amount moisture recycling achievees the effect that the energy-efficient of whole system.Whole device has energy-saving and environmental protection and structure is simply convenient for grasping
The advantages of making.
The present invention can also make improvement as follows or preferred：
Further：Heating device 14 is electric heating part.Thus make that the structure of air-treatment unit 100 is simple, manufacturing cost
It is low.
Enter the air of constant temperature and humidity component 1 and the fresh air of fresh air bypass component 2 to filter, avoids empty due to entering
The gas of gas disposal unit 100 is not clean and the case where causing related components working efficiency low or damage.
Preferably：Constant temperature and humidity component 1 further includes first filter 18；First filter 18 is arranged in the first air mixing channel
Between 11 and surface air cooler 12.
Preferably：Fresh air bypass component 2 further includes the second filter 21；Second filter 21 is arranged in fresh air channel

Set channel 22；The connection of mixer selector valve 104 disconnects the second air mixing channel 13 and postposition channel 23.It should be noted that fresh air bypass group
Fresh air in part 2 is to suck from analog channel 22, then enter the first air mixing channel 11 of constant temperature and humidity component 1 through new air-valve 103
Or the second air mixing channel 13 through postposition channel 23,104 constant temperature and humidity component 1 of mixer selector valve.
Optionally, each of first filter 18 and the second filter 21 all can be air filter, to make
The structure of air-treatment unit 100 is simpler, manufacturing cost further decreases.
By constant temperature and humidity, treated that air passes through more quickly that air-supply passage 16 enters user's use space in order to make,
Constant temperature and humidity component 1 can also include blower 17, and blower 17 is located in air-supply passage 16.It similarly, can also be in analog channel 22
With in postposition channel 23 be equipped with blower.
The present invention also announces a kind of control method of air-treatment unit comprising following step：
Compared according to the size of indoor humidity and setting humidity：
When indoor humidity is lower than setting humidity, controller controls the closing of mixer selector valve 104, new air-valve 103 is opened, at air
Manage unit operation；The operation of air-treatment unit, indoor humidity are consistently less than control after setting humidity 5 to 20 seconds (preferably 10 seconds)
Device controls humidifier 15 and opens humidification.
When indoor humidity is higher than setting humidity, controller controls humidifier 15 and stops humidification, air-treatment unit fortune
Row；The operation of air-treatment unit, indoor humidity are persistently higher than after setting humidity 5 to 20 seconds (preferably 10 seconds), then controller controls
Mixer selector valve 104 is opened, new air-valve 103 is closed.
A kind of control method of air-treatment unit further includes following steps：
Compared according to the size of room temperature and set temperature：
When room temperature is lower than set temperature, controller controls heating device and opens, the control heating of on the contrary then controller
Device is closed.
Below by taking a specific example as an example, illustrate the energy-saving effect of air-treatment unit 100 according to the present invention：
Customer requirement parameter：Return air operating condition：Dry-bulb temperature：27 DEG C, wet-bulb temperature：19.5 DEG C, relative humidity：50.4%；
Fresh air operating condition：Dry-bulb temperature：35 DEG C, wet-bulb temperature：28℃；It is required that：Air quantity is：85000m3/h, fresh air 10%；Machine is outer remaining
Pressure:700Pa, refrigerating capacity：561kw, electric heating amount：180KW, electrode humidification amount:45kg/h.
The treatment process of air-treatment unit 100 is as follows：Operating condition after mixed wind：Dry-bulb temperature：27.8 DEG C, wet-bulb temperature：
20.5℃；The operating condition after surface air cooler：Dry-bulb temperature：14.7 DEG C, wet-bulb temperature：It 13.9 DEG C, needs to provide 561KW herein cold
Amount；Since customer requirement reaches constant temperature and humidity effect, therefore air needs heat temperature raising to handle after surface air cooler, so increasing
Electric heater, the heating amount that electric heating needs are 180KW.
The following are the data analyses for increasing fresh air system constant temperature and humidity unit：
Customer requirement parameter：Return air operating condition：Dry-bulb temperature：27 DEG C, wet-bulb temperature：19.5 DEG C, relative humidity：50.4%,
Water capacity：11.2g/Kg；Fresh air operating condition：Dry-bulb temperature：35 DEG C, wet-bulb temperature：28 DEG C, water capacity：21.8g/Kg；It is required that：Wind
Amount is：85000m3/h, fresh air 10%；Margin blast pressure:700Pa, refrigerating capacity：561kw, electric heating amount：180KW, electrode humidification
Amount:45kg/h.
The treatment process of air-treatment unit 100 is as follows：Return air is 76500m3/h, return air work after surface air cooler is handled
Condition：Dry-bulb temperature：14.7 DEG C, wet-bulb temperature：13.9 DEG C, water capacity：9.6g/Kg, the cooling capacity handled herein are：425KW；Newly
Wind passes through filtration treatment, operating condition after mixing with return air：Dry-bulb temperature：16.7 DEG C, wet-bulb temperature：15.8 DEG C, water capacity：
10.82g/Kg；Since customer requirement reaches constant temperature and humidity effect, therefore air needs at heat temperature raising and humidification after surface air cooler
Reason is known that by calculating：Mixed air also needs to increase ability after the heating amount of 112KW and the humidification amount of 10.8Kg/h
It is able to satisfy customer requirement.
Above data analysis is it is recognised that the constant temperature and humidity unit with fresh air treatment system saves at the cold place of table
The cooling capacity of (561-425=) 136KW is put into, and the heat investment of (180-112=) 68KW is saved in bringing-up section, in humidifier section section
The moisture investment for having saved (45-11=) 34Kg/h, by calculating, the energy that can achieve about 30% or so is saved, therefore entire system
System can save biggish energy loss, meet energy-efficient effect.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
