Utility model content
Fresh air handling units (FAU) are the air processors for focusing on outdoor fresh air, and Fresh air handling units are mainly by fresh air
Valve, filter, surface-type heat exchanger, humidifier, pressure fan etc. are constituted.Outdoor fresh air enters Fresh air handling units after strainer filtering,
Heat and wet treatment is carried out by surface-type heat exchanger, can be by humidifier humidifies when air humidity is lower than setting value, it is empty that treated
Gas is distributed in each air-conditioned room by pressure fan.
The control of Fresh air handling units is generally according to the demand of owner and " Standsrd for design of intelligent buildings " (GB/T50314-2000)
In the monitoring function of air treatment system is required to be designed, the purpose of this utility model is to provide a kind of air-treatment systems
The monitoring device of system, is monitored Fresh air handling units, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of monitoring device of air treatment system, including field controller, air-supply Temperature Humidity Sensor TH, frost prevention switch

When starting, new air-valve is opened；Pressure fan stops, and coil frost broken after new air-valve closing can prevent winter from shutting down in this way reduces ash
Dirt enters, and keeps cleaning in Fresh air handling units.
As a further solution of the present invention: the filter screen status display refers to alarm: being filled in strainer two sides
If pressure difference switch, the unimpeded situation of filter screen is monitored, when fan operation, if filter screen is clean, pressure difference is less than before and after strainer
Setting value；, whereas if filter screen dust stratification increases, the pressure difference before and after strainer becomes larger, and when being more than setting value, micro differential pressure switch is just
It can be closed, the switching signal of this closure inputs field controller by DI all the way, and controller issues alarm, reminds staff
It is cleaned.
As a further solution of the present invention: the Detection & Controling of the air-supply temperature and humidity refer to: in Fresh air handling units
Exit sets humiture transducer, is connected in 1 road AI input channel of field controller, respectively to the dry-bulb temperature of air and phase
Humidity is monitored, whether to understand unit by Fresh air handing to required state.Fresh air temperature and humidity measured value with set
Definite value compares, and by its difference by PID arithmetic, exports the 0-10V signal of simulation, cold/hot water valve opening is adjusted, simultaneously
The switch of humidifier valve is controlled, to maintain the setting value of air-supply temperature and humidity.Wherein, when winter condition hot water valve and new air temperature at
Inverse proportion, cold valves and new air temperature are in direct ratio when summer operating mode.When winter carries out humidification control, electromagnetism is generally used
The control of valve dibit.In order to reduce maximum deviation and fluctuation, through humidifying frequently with multistage, i.e., when humidity deviation is big, multiple groups add
Wet device work, deviation reduction then reduce humidifier working quantity.
As a further solution of the present invention: the control of the anti-frost protection refers to: the effect of anti-frost protection is anti-
Only winter coil frost broken generally uses following measure: first is that pressure fan and new air-valve door linkage；Second is that when unit is out of service
When, the dynamoelectric water valve of coil pipe still keeps the aperture of 10%-30%, to guarantee having certain hot water circuit；Third is that being changed in surface-type
Frost prevention switch TS is installed behind hot device, operating temperature is generally located on 5 DEG C, when the air themperature at frost prevention switch is lower than 5 DEG C,

Dynamic state (DI signal)；Take the auxiliary contact signal of electrothermal relay on fan electromotor primary circuit as blower overload shutdown report
Alert signal (DI signal)；Generally there are two types of implementations for the Stateful Inspection of blower: one is directly from blower electric cabinet contactor
The auxiliary contact number of winning the confidence；Another kind is to add pressure difference switch at blower both ends, differentiates fan condition according to Pressure difference feedback.First
Kind method simple economy, second method can accurately judge the actual motion state of blower；Boot sequence control are as follows: starting
New blower-unlatching fresh air air-valve-unlatching simultaneously adjusts water side electric control valve (winter)-conditioning moisturer motor-driven valve；Shutdown sequence
Control are as follows: close new blower-closing fresh air air-valve-closing humidifier motor-driven valve-closing water side electric control valve；Field controller
It is connected by communication line and the system controller of control centre, so that it may realize the long-range monitoring of Fresh air handling units.
As a further solution of the present invention: the fire-fighting chain control refers to: when fire occurs, by Fire Fighting Company
Lock control issues signal, stops fan operation, and close new air-valve by the channel DO on 1 tunnel, the opening/closing state of new air-valve passes through DI
It is sent into monitor.
As a further solution of the present invention: the VAV control refers to: air quality being arranged indoors and senses
Device detects CO2Content is connected to the AI terminal of fan frequency converter by 1 road AI input, wanted when indoor air quality meets setting value
When asking, pressure fan frequency of supply (having minimum running frequency to limit, generally to guarantee minimum supply air rate) can be reduced, fresh air is reduced
Amount, with energy saving (can reduce new wind load, fan operation energy consumption)；When indoor air quality is unsatisfactory for setting value requirement
When, increase pressure fan running frequency, increases fresh air volume；This is compared with the control program of traditional fixation minimum fresh air requirmente, with CO2
Concentration, which is sent into indoor fresh air volume as the control of index, has apparent energy-saving effect.
In supply air temperature and humid control, to pay special attention to handle under summer operating mode by the cooling and dehumidification of surface air cooler
Process；Because temperature and humidity have correlation, generally in comfort air conditioning system, can using peak signal select by the way of,
I.e. temperature deviation and humidity deviation select the larger value to carry out PID arithmetic, electric water of the output signal to surface air cooler by comparator
Valve opening is adjusted, to guarantee that temperature and humidity fluctuates within the limits prescribed.
Compared with prior art, the utility model has the beneficial effects that
