Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to specific implementation
The utility model is described in further detail for mode.
As shown in Figure 1, the utility model includes controller, the controller with the fresh-air fan of fresh wind port is set, is returned
The return air fan in air port, the breeze fan of air outlet are connected；It further include the temperature sensor for testing outdoor temperature and survey
Try the gas concentration lwevel sensor of indoor carbon dioxide concentration, the temperature sensor and gas concentration lwevel sensor and control
Device connection processed.It further include the air duct switching device for switching fresh wind port and return air inlet air duct, the air duct switching device and control
Device connection processed.The fresh-air fan, return air fan, breeze fan revolving speed be 400-1200rpm.(settable) further include with
The long distance wireless R-T unit of controller connection；The long distance wireless R-T unit is connect with remote control apparatus.Long-range control
Device is smart phone.The time relay for controlling fresh-air fan and return air fan alternate run is provided on controller.
As shown in Fig. 2, the control method of the utility model the following steps are included:
Step A obtains gas concentration lwevel information in outdoor temperature information and room air；New blower is as shown in figure 3, packet
Shell is included, fresh wind port 1, return air inlet 2 and air outlet 3 are provided on shell, fresh-air fan F1, return air are installed on fresh wind port 1
Mouth 2 is equipped with return air fan F2, air outlet 3 is provided with breeze fan F3, the fresh-air fan F1, return air fan F2, air-supply wind
Machine F3 is one of voltage rating 12V, 24V and 220V.It is provided with air duct switching device 7 between fresh wind port and return air inlet 1, uses
In switching air duct.Electrostatic precipitator and heat storage are disposed between air duct switching device 7 and air-supply air port 3.Controller
Temperature information and gas concentration lwevel information are obtained by temperature sensor and gas concentration lwevel sensor.
Step B, the operating of blower includes two modes in the utility model: first is that all-fresh air mode, when outdoor temperature not
Less than 18 DEG C and when being not more than 26 DEG C, it is only used for introducing the fresh-air fan F1 of fresh air and is introduced for the air-flow into new blower
Indoor breeze fan F3 is operated simultaneously.
Second is that circulated air mode, when outdoor temperature is less than 18 DEG C or is greater than 26 DEG C, fresh-air fan F1, for will be indoor
Air introduces the return air fan F3 alternate-running in new blower, and breeze fan often turns；Fresh-air fan and return air fan are alternate
Time is 0-999 seconds adjustable, and process is to close fresh wind port first with controller control air duct switching valve, opens return air inlet, returns
The operating of wind blower, indoor return air carry out heat exchange with heat storage after sterilizing dedusting.When heat storage is consistent with gas flow temperature
Afterwards, return air fan F2 and return air inlet are closed, and fresh-air fan F1 and fresh wind port are opened, and from outdoor introducing fresh air, fresh air is by sterilization
Heat exchange occurs with heat storage after dedusting, reduces the temperature difference of fresh air and room air, improves comforts of use.Work as accumulation of heat
After body is consistent with new air temperature, fresh-air fan F1 and fresh wind port are closed, return air fan F2 and return air inlet is opened, so recycles.It is whole
A process pressure fan F3 is normally opened.
Step C controls rotation speed of fan by gas concentration lwevel in room air；When gas concentration lwevel is in 400PPM
When following, according to the blower that temperature information judgement needs to operate in step B with the operation of revolving speed 400rpm low speed.For example, in fresh air
Under mode, when indoor carbon dioxide concentration is 300PPM, fresh-air fan F1 and breeze fan F3 are with 400rpm revolving speed low speed
Operation.
When gas concentration lwevel is in 1200PPM or more, according to temperature information judgement in step B need the blower that operates with
Revolving speed 1200rpm high-speed cruising；When gas concentration lwevel is between 400-1200PPM, judged according to temperature information in step B
The revolving speed for the blower for needing to operate stepping between 400rpm and 1200rpm is run, and the concentration of revolving speed and carbon dioxide is at just
Than.For example, when indoor carbon dioxide concentration is 800PPM, fresh-air fan F1, return air fan F2, being sent under circulated air mode
Wind blower F3 is run with the revolving speed of 800rpm, and fresh-air fan F1 and return air fan F2 is primary every 70 seconds alternate runs.
Certainly, the revolving speed of blower can also be divided into such as 400,600,800,1000, the several class of 1200rpm, work as titanium dioxide
Concentration of carbon blower in 400PPM or less is run with deep low gear 400rpm, and the wind when gas concentration lwevel is in 1200PPM or more
Machine is with most high-grade 1200rpm operation.When gas concentration lwevel is between 400-1200PPM, can be existed according to concentration difference
600, several gear operations such as 800,1000.
In the application, carbon dioxide preset concentration C1, C2, outdoor temperature T1, T2 and rotation speed of fan can be according to practical feelings
Condition, which is made, to be adaptively adjusted.
Above are merely preferred embodiments of the utility model, it is noted that above-mentioned preferred embodiment should not regard
For limitations of the present invention, the protection scope of the utility model should be defined by the scope defined by the claims..For
For those skilled in the art, without departing from the spirit and scope of the utility model, it can also make several
Improvements and modifications, these improvements and modifications also should be regarded as the protection scope of the utility model.
