Description
Technical field
The present invention relates to a kind of ventilation unit, more particularly to a kind of bidirectional flow main frame and its control method.
Background technology
Displacement of the ventilation unit to realize indoor and outdoors air.The pipe of outdoor is connected in the main frame of existing ventilation unit
If being not provided with valve on road, then when a host is turned off, reverse flowing of air flows can be caused, winter cold air or summer are hot
Air can be got in, and cause indoor energy loss.Meanwhile, when outdoor environment is severe, when wind speed is very big, during into pipeline, meeting
Trigger howling.Even rainwater enters main frame, so as to cause failure.
Thus, it will usually connected in the main frame of existing apparatus on the piping outside the house and non-return valve is installed, when air following current,
Flap is opened by air thrust, when air arrheas, and flap is leaned on to be dropped on valve seat from vertical or spring, is risen and is prevented an air inversion from making
With.But such valve opening needs the promotion of air, the increase of pipeline crushing is caused, air quantity reduces.Meanwhile, such valve only has
It is opened and closed two states, it is impossible to the Intelligent adjustment aperture according to situations such as air purity and outdoor temperature.
Also, the main frame of existing ventilation unit is designed with energy regenerating to reach energy recovery function inside machine
Nuclear component.It is generally indoor due to heating equipment influence the temperature of indoor exhaust wind to be made to compare room when machine is run in cold district
The temperature of outer fresh air is high.When outdoor air draft carries out energy exchange, due to the reduction of its temperature, it is easy to cause moisture in air to coagulate
Knot, and the tiny air channel on energy regenerating core produces frost phenomenon, causes the motor inside machine to burn out, gas channel is blocked
Wait indefinitely failure, the problem of stopping fresh air supply in outlet room.And main frame in the market does not possess frost protection function, therefore
All it is not suitable for north cold area.
In addition, it is generally the case that northern winter is relatively dry, room air needs humidification, and outdoor temperature is very low, many institutes
Known, temperature is lower, and humidifying effect is poorer.Common product is in humidification, it is impossible to cuts off outdoor fresh air, causes indoor wind pushing temperature
Still very low, humidifying effect is impacted.

PVC airducts are connected by close-fit sealing ring；Thus, at air port connector 12 and wind pipe connector 13 all without band so as to
It is easy for installation and removal, and is equipped with rubber gasket, makes the favorable sealing property of hose adapter 11, the possibility of gas-tight.
The specific size of air port connector 12 and wind pipe connector 13 should be mutually matched with the air port of main frame and the size of PVC airducts.
When bidirectional flow main frame is in normal operation mode as shown in Figure 10, described outdoor exhaust outlet 1 and outdoor are new
Electronic valve 9 on air port 2 is switched on, and the pipeline of the indoor return air mouthful 4 connects outdoor exhaust outlet 1 via heat exchange core 5
Pipeline, to the air draft in conveying chamber；Meanwhile, the pipeline of the outdoor fresh air mouthful 2 passes through the communication chamber inner wind outlet of heat exchange core 5
3 pipeline, the fresh air to convey outdoor.Indoor air draft and outdoor fresh air, are flowed in the different layers of heat exchange core 5
It will not intersect, and energy regenerating is carried out by heat exchange core 5.For example, outside air temperature can be detected in temperature sensor
During higher than 0 DEG C, bidirectional flow main frame is set to be in above-mentioned normal operation mode.
When bidirectional flow main frame is run, the electronic valve 9 in described outdoor exhaust outlet 1 and outdoor fresh air mouthful 2 is all opened,
Realize the indoor convection current with outdoor air；When a host is turned off, these electronic valves 9 are all closed, so as to prevent external air flow from falling
Fill.
When the bidirectional flow main frame of the present invention is opened, the outdoor temperature that can also be detected according to temperature sensor, from
The aperture of electronic valve 9 in dynamic the regulation outdoor exhaust outlet 1 and outdoor fresh air mouthful 2：
When outdoor temperature is less than 10 degree（10 DEG C of T ＜）When, electronic valve closes the mould of 30 minutes afterwards to open 3 minutes
Formula is operated.Now, electronic valve aperture is between 0 ~ 45 degree.It is preferred that example in, electronic valve is opened during -20 DEG C of temperature ~ 10 DEG C
Degree is in 0 ~ 45 degree of linear change.And at less than -20 DEG C, electronic valve is completely closed.
When outdoor temperature T is more than or equal to 10 degree and less than 20 degree（20 DEG C of 10 DEG C≤T ＜）When, electronic valve is to close 45
The state operation of degree；
When outdoor temperature is more than or equal to 20 degree and less than or equal to 25 degree（20℃≤T≤25℃）When, electronic valve with
Full-gear is run；
When outdoor temperature is more than 25 degree and less than 35 degree（25 DEG C of 35 DEG C of ＜ T ＜）When, electronic valve is to close 45 degree of shape
State is run；

The mode operation of clock.Operation mode at more than 35 DEG C is similar with situation at less than 10 DEG C.Electronic valve aperture is at 0 ~ 45 degree
Between.
The bidirectional flow main frame of the present invention, the outdoor temperature that can also be detected according to temperature sensor passes through control
The electronic valve 9 at bypath valve 8 and air port in main frame, runs on interior circulation frost protection pattern：
When temperature sensor detects outdoor temperature T less than 0 degree（0 DEG C of T ＜）When, main frame can run well 25 minutes, it
Afterwards with interior circulation frost protection mode operation 5 minutes.
As shown in figure 11, in described interior circulation frost protection pattern, the electricity in outdoor exhaust outlet 1 and outdoor fresh air mouthful 2
Sub- valve 9 is all closed, and completely cuts through outdoor fresh air；Also, bypath valve 8 is opened, makes the pipeline of outdoor exhaust outlet 1 and outdoor new
The pipeline communication in air port 2.Thus, temperature is higher（Usually above 12 DEG C）Indoor return air can pass twice through heat exchange core 5, carry
High frost protection effect：That is, indoor return air is connected by indoor return air mouthful 4, heat exchange core 5 with being opened through bypath valve 8
After 2 pipelines of outdoor exhaust outlet 1 and outdoor fresh air mouthful, interior is sent back to again by heat exchange core 5, and via indoor air outlet 3.
The bidirectional flow main frame of the present invention, ultrasonic humidifying section 10 can also be set at air outlet 3, and pass through indoors

The indoor return air mouthful（4）, heat exchange core（5）, outdoor exhaust outlet（1）Pipeline, open bypath valve（8）, it is outdoor new
Air port（2）Pipeline, heat exchange core（5）, indoor air outlet（3）And its ultrasonic humidifying section（10）, indoor return air is led to twice
Cross the heat exchange core（5）Send interior after humidifying again back to；
Wherein, outside air temperature T is detected by temperature sensor；
When T >=0 DEG C, bidirectional flow main frame is in normal operation mode；
As 0 DEG C of T ＜, bidirectional flow main frame operated 25 minutes with normal operation mode after with 5 points of interior circulation frost protection mode operation
The mode of clock is run.
