Exemplified by air exchange process, the control method of the present invention is illustrated.
With reference to the structure of the subway's air-conditioning system in previous embodiment, the specific control to subway's air-conditioning system of the present invention
Flow processed illustrates.
Fig. 2 is the flow chart of the control method of the subway's air-conditioning system of the present invention according to shown by an exemplary embodiment
One.As shown in Fig. 2 the invention provides a kind of control method of subway's air-conditioning system, available under different working conditions to sky
The switching of the air vent mode of adjusting system, so that air vent mode can be adapted with current working, meet under subway enclosed environment
Ventilation demand；Specifically, control method of the present invention mainly includes the following steps that：
Ambient parameter during S201, acquisition operation of air conditioner；
In the present embodiment, the ambient parameter during operation of air conditioner may include indoor ambient parameter and outside environment
Parameter, for example, indoor ambient parameter includes the parameters such as indoor temperature, indoor humidity, gas concentration lwevel, due to indoor
Ambient parameter can directly influence the impression for the passenger for being in subway indoor space, and therefore, the air vent mode of air-conditioning can basis
The change of indoor ambient parameter switches over.
Equally, outside ambient parameter includes the parameters such as outdoor temperature, outside humidity, due to the Metro Air conditioner system of the present invention
System needs the air of outside being conveyed into the environment of indoor, and therefore, the ambient parameter of outside will have influence on indoor side ring
The change in border, so, the ambient parameter of outside is also an important factor for present invention control air vent mode switches.
S202, according to ambient parameter, determine the air vent mode of air-conditioning, air vent mode include to indoor conveying indoor return air with
The small fresh air pattern for the mixing wind that outdoor fresh air mixes, and the all-fresh air pattern to indoor conveying outdoor fresh air；
In the present embodiment, small fresh air pattern is to be re-fed into indoor environment after mixing indoor return air and outdoor fresh air
In, usually differed greatly suitable for outside ambient parameter and indoor ambient parameter, or the temperature of outside, humidity or sky
The factors such as makings amount are worse than the situation of indoor.
For example, in summer condition, outdoor air temperature, the humidity on daytime are typically higher, and the outdoor air in evening
Temperature, humidity are then relatively low, and in the running of the whole day of subway's air-conditioning system, and the air themperature of indoor and humidity are general
Outside is less than, is more conform with the requirement of comfort of passenger, therefore, if in summer day by outdoor lateral indoor
A large amount of conveying air, the temperature and humidity rise of indoor is may result in, causes user uncomfortable, and again by indoor temperature and wet
Degree, which is reduced to the temperature and humidity value that user feels comfortably cool, also can additionally increase the power consumption of air-conditioning.
Or operating mode in the winter time, daytime outdoor air temperature, humidity it is typically slightly higher, and evening outdoor air temperature,
Humidity is then relatively low, and air is in the running of the whole day of subway's air-conditioning system, and the air themperature of indoor and humidity are general
Outside is above, is more conform with the requirement of comfort of passenger, therefore, if in the winter time at night by outdoor lateral indoor
A large amount of conveying air, may result in the temperature and humidity of indoor reduces, and causes user uncomfortable, and again by indoor temperature and wet
Degree, which is increased to the temperature and humidity value that user feels comfortably cool, also can additionally increase the power consumption of air-conditioning.
Therefore, in the case of foregoing two kinds, if part room air to be discharged mixed with the air of outside,
The effect of neutralization can be then played, it is excessive so as to avoid outdoor air from changing indoor environment, and reduce the extra power of air-conditioning
Consumption；Therefore, small fresh air pattern differs greatly suitable for outside ambient parameter with indoor ambient parameter, or the temperature of outside
The factors such as degree, humidity or air quality are worse than the situation of indoor.
In the present embodiment, all-fresh air pattern is the new of all outsides of air that air-conditioning system is sent into indoor environment
Wind, it is usually smaller suitable for outside ambient parameter and indoor ambient parameter difference, or the temperature of outside, humidity or sky
The factors such as makings amount are better than the situation of indoor.
For example, in summer condition, if largely conveying air by outdoor lateral indoor at night, outdoor air is to room
The heating of inner side and the interference effect of humidification are smaller, the experience of the comfort level of user is influenceed it is relatively low, and again by indoor temperature and
The power consumption that humidity is reduced to the air-conditioning for the temperature and humidity value that user feels comfortably cool is also smaller.
Or operating mode in the winter time, if largely conveying air by outdoor lateral indoor in the winter time, outdoor air is to room
The cooling of inner side and the interference effect of dehumidification are smaller, the experience of the comfort level of user is influenceed it is relatively low, and again by indoor temperature and
The power consumption that humidity is increased to the air-conditioning for the temperature and humidity value that user feels comfortably cool is also smaller.
Therefore, in the case of foregoing two kinds, all-fresh air pattern can be used, to increase sending by outdoor lateral indoor
Air quantity, improve scavenging efficiency；Therefore, all-fresh air pattern be applied to outside ambient parameter and indoor ambient parameter difference compared with
It is small, or the factor such as the temperature of outside, humidity or air quality is better than the situation of indoor.
S203, control air-conditioning switch to the air vent mode of determination.
So, control method of the present invention can be according to the relevant parameter of subway external environment condition, it is determined that the ventilation being currently adapted to
Pattern, by the switching of small fresh air pattern and all-fresh air pattern, the Ventilation Control of Metro Air conditioner can be made to disclosure satisfy that current work
Ventilation under condition needs, and improves the usage experience of the passenger of subway public area, while also reduce the operation energy of Metro Air conditioner
Consumption, reduce the operating cost of Metro Air conditioner.
In an embodiment of the present invention, due to summer condition and the outside environmental factor of winter condition and the ring of indoor
Border factor difference is different, it is therefore desirable to which the ambient parameter of detection is also different.Preferably, the present invention is performing foregoing control flow
Before, residing operating mode is run to current subway's air-conditioning system first and carries out judgement determination, for example, subway's air-conditioning system can be advance
It is determined that current seasonal climate, afterwards, detects corresponding ambient parameter according to the seasonal climate of determination, is selected further according to ambient parameter
Determine the air vent mode of air-conditioning.
The operating mode that the present invention is run subway's air-conditioning system is divided into non-winter condition (or summer condition) and winter condition,
And divided according to month, for example, winter condition will be divided into the March in annual November to next year, and annual April
Part is then divided into non-winter condition to October, and so, subway's air-conditioning system can be worked as by built-in calendar or online query
On the preceding residing date in month, the operating mode according to residing for current month can determine subway's air-conditioning system, e.g., worked as by inquiry
The preceding date in month is August, then according to above-mentioned month division principle, can determine that residing for air-conditioning for non-winter condition.So, may be used
According to the operating mode currently determined, corresponding ambient parameter is detected.
By taking non-winter condition as an example, the ambient parameter during operation of air conditioner acquired in step S201 includes：Outdoor environment
The first outdoor temperature and the first outside humidity.In the present embodiment, subway's air-conditioning system is provided with temperature sensor, wet and dry bulb
With the sensing detection part such as humidity sensor, available for the current outdoor temperature and current outdoor humidity of detection outdoor environment, this
Sample, it is possible to further empty using current outdoor temperature as the first outdoor temperature, current outdoor humidity as the first outside humidity
The air vent mode of operation required for adjusting.
Specifically, the present invention can calculate according to the first outdoor temperature and the first outside humidity and determine outdoor fresh air enthalpy, with
Outdoor fresh air enthalpy is as the parameter for determining air conditioner ventilation pattern.The calculation of the enthalpy of outdoor air can be by art technology
Personnel are calculated according to prior art, and the present invention does not repeat.
In general, in the case that outdoor temperature under non-winter condition is higher, humidity is higher, the enthalpy of outdoor fresh air air
It is bigger, therefore, it is delivered to that the air quantity of the outdoor fresh air of indoor is bigger, it is also bigger to the interference effect of indoor environment.
Therefore, it is excessive in order to avoid the temperature and humidity condition change of indoor environment, when outdoor fresh air enthalpy is more than default first return air enthalpy
During value, determine air-conditioning with small fresh air mode operation.
So, because the humiture situation of room air to be discharged is close to the warm and humid situation of indoor, therefore, pass through
Part room air to be discharged is mixed with the air of outside, the effect of neutralization, the temperature of mixed air can be played
Humidity value is less than the air in outdoor environment, therefore, by conveying mixing wind to indoor, can avoid outdoor air pair
Indoor environment changes excessive.
Specifically, when subway's air-conditioning system needs to switch to small fresh air pattern, the connection of present invention control supply air duct 1
The all-fresh air air-valve 32 of outside is closed, and to reduce intake, avoids, because outside leaked-in air is excessive, causing neutralization
Unobvious；Meanwhile the small fresh air air-valve 33 on the outside of the communication chamber of supply air duct 1 is opened, the air of outside passes through small fresh air wind
Valve 33 enters in supply air duct 1；The exhaust valve of wind output channel 2 is opened, and the air of indoor can be expelled to via wind output channel 2
In outdoor environment, so as to be combined with supply air duct 1, the ventilation of indoor and outside is realized.
In addition, the part of air returning valve 5 of connection supply air duct 1 and wind output channel 2 is opened, so, the portion of wind output channel 2 is flowed through
Room air is divided to flow into supply air duct 1 via air returning valve 5；Specifically, because the negative pressure of wind output channel 2 is then positioned near indoor
Side side, the suction side of supply air duct 1 are located at nearly outside side, therefore, the pressure of the side of the nearly outside of wind output channel 2
It is higher than the air pressure of the nearly outside side of supply air duct 1, because the first mixation tube section 16 and the second mixation tube section 24 are equal
It is to be located at nearly outside side, therefore, the part room air of wind output channel 2 can flow under suction function via air returning valve 5
Enter in supply air duct 1.
Preferably, in order to improve the mixed effect of indoor return air and outdoor fresh air, the warm and humid difference of outdoor fresh air is reduced, can
By modes such as the unlatching aperture for heightening air returning valve 5, the operation power for increasing pressure fan, improve indoor return air and flow into supply air duct
1 air quantity；Similarly, it is excessive that the air quantity of supply air duct 1 is flowed into order to avoid indoor return air, can also be by turning down air returning valve 5
Open the modes such as aperture, the operation power for reducing pressure fan to realize, to reduce the air quantity that indoor return air flows into supply air duct 1.
The first exhaust valve 41 of nearly indoor and the second row of nearly outside are respectively arranged with the wind output channel 2 of the present invention
Air-valve 42, because the part indoor return air under small fresh air pattern flows into supply air duct 1, the air quantity for flowing through the first exhaust valve 41 is
Flow through the air quantity sum of the second exhaust valve 42 and air returning valve 5, it is therefore advantageous to, the first exhaust valve 41 can use be all turned on,
Second exhaust valve 42 is by the way of the unlatching of part valve degree, and with the opening valve degree of combination air returning valve 5, return air is flowed into and sent in regulation room
The air quantity in wind air channel 1.
For example, it can improve the mode of the valve degree of air returning valve 5 by turning the second exhaust valve 42 valve degree down, raise air draft
The air pressure of the nearly outside in air channel 2, so, can be with the air pressure in increasing exhaust air channel 2 and the nearly outside of supply air duct 1
Difference, improve transfer efficiency of the indoor return air to supply air duct 1.
In an alternative embodiment of the invention, the ambient parameter during operation of air conditioner acquired in step S201 includes：It is outdoor
3rd outdoor temperature of environment and the 3rd outside humidity.And it can be calculated according to the 3rd outdoor temperature and the 3rd outside humidity and determine room
Outer fresh air enthalpy；When outdoor fresh air enthalpy is less than default 3rd return air enthalpy, and the 3rd outdoor temperature is more than default ventilation
During change working temperature, determine air-conditioning with all-fresh air mode operation.
So, it is less than default 3rd return air enthalpy in outdoor fresh air enthalpy, and the 3rd outdoor temperature is more than default lead to
In the case of wind change working temperature, outdoor temperature and outside humidity and the humiture difference of indoor are smaller, even below room
The humiture of inner side, therefore, under summer condition, by the way that to a large amount of outdoor fresh airs in indoor, indoor environment temperature can be accelerated
The reduction of degree and humidity, subway's air-conditioning system is decreased in its cooling, the energy consumption of the dehumidifying course of work.
Specifically, when subway's air-conditioning system needs to switch to all-fresh air pattern, the connection of present invention control supply air duct 1
The all-fresh air air-valve 32 of outside is opened, and to increase intake, the air of outside enters air-supply wind by all-fresh air air-valve 32
In road 1；Meanwhile the small fresh air air-valve 33 on the outside of the communication chamber of supply air duct 1 is closed, part is opened or standard-sized sheet；Wind output channel 2
Exhaust valve open, the air of indoor can be expelled in outdoor environment via wind output channel 2, so as to the phase of supply air duct 1
With reference to realizing the ventilation of indoor and outside.
In addition, the air returning valve 5 of connection supply air duct 1 and wind output channel 2 is closed, so, it can stop and flow through wind output channel 2
Part room air flow into supply air duct 1 via air returning valve 5, to avoid indoor return air and outdoor fresh air from neutralizing.
By taking winter condition as an example, the ambient parameter during operation of air conditioner acquired in step S201 includes：Under winter condition
The second outdoor temperature.
In general, in the case of outdoor temperature under winter condition is relatively low, the air quantity for being delivered to the outdoor fresh air of indoor is got over
Greatly, it is also bigger to the interference effect of indoor environment.It is therefore, excessive in order to avoid the temperature conditionss change of indoor environment,
When the second outdoor temperature is less than default winter condition opening temperature, determine air-conditioning with small fresh air mode operation.
So, because the humiture situation of room air to be discharged is close to the temperature conditions of indoor, therefore, pass through
Part room air to be discharged is mixed with the air of outside, the effect of neutralization, the temperature of mixed air can be played
Angle value is greater than the air in outdoor environment, therefore, by conveying mixing wind to indoor, can avoid outdoor air to room
