Port is connect with the input terminal of the input terminal of subtracter, comparator respectively, the digital signal input end mouth and memory of processor,
The output end connection of the output end, subtracter of comparator；The dirty stifled pressure limit decision content of condenser, entrance are stored in memory
Pressure sensor, outlet pressure sensor acquisition pressure simulation signal be transmitted to processor, processor is by pressure simulation signal
The input terminal for being sent into subtracter after digital signal is converted to, subtraction process is carried out in subtracter and obtains pressure difference value, pressure difference value
Processor is sent back in the form of digital signal by subtractor outputs, and processor is again sent pressure difference value in the form of digital signal
Enter comparator input terminal, simultaneous processor reads in memory the dirty stifled pressure limit decision content of condenser and by the dirty stifled pressure of condenser
Power boundary decision content is sent into comparator input terminal, comparator stifled pressure dirty to pressure difference value and condenser in the form of digital signal
Boundary decision content is compared to obtain comparison result, and comparison result is sent back to processing by comparator output terminal in the form of digital signal
Device.
2, the dirty stifled warning device of a kind of condenser according to claim 1, it is characterised in that：If pressure difference value is greater than
The dirty stifled pressure limit decision content of condenser, then processor generates alarm analog signal and is sent into alarm module, drives alarm module
Work alarm.
A kind of dirty stifled warning device of condenser, it is characterised in that：The alarm module is police instruction circuit for lamp
Module.
A kind of dirty stifled warning device of condenser, it is characterised in that：The dirty stifled pressure limit decision content of condenser
It is counted and is obtained according to the pressure difference value in the different dirty stifled situation lower inlet air ducts of condenser and outlet conduits.
The present invention can accurately judge the dirty stifled situation of condenser, and its it is serious it is dirty it is stifled before sound an alarm to user,
Remind user clean condenser in time, can effectively avoid the adverse consequences because of the dirty stifled generation of condenser, at the same reduce user because
Worry the dirty stifled process frequently checked.
Compared with prior art, advantages of the present invention is：
1, the present invention for can the dirty stifled situation of accurate judgement condenser, and sound an alarm in time.
2, present invention control is simple, convenient, and reliable, it is easy to accomplish module design.
Detailed description of the invention
Fig. 1 is structure of the invention schematic diagram.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, a kind of dirty stifled warning device of condenser, including control panel 4, it is arranged in 1 inlet conduits of condenser
Inlet pressure transducer 2, the outlet pressure sensor 3 and alarm module 5 that are arranged in 1 outlet conduits of condenser, control
Plate 4 has been internally integrated processor, subtracter, comparator, memory, and inlet pressure transducer 2, outlet pressure sensor 3 are distinguished
It is connect with the analog signal input port of processor, the analog signal output mouth of processor is connect with alarm module 5, the number of processor
Word signal output port is connect with the input terminal of the input terminal of subtracter, comparator respectively, the digital signal input end of processor
Mouth is connect with the output end of memory, the output end of comparator, subtracter；The dirty stifled pressure limit of condenser is stored in memory
Decision content, the pressure simulation signal that inlet pressure transducer 2, outlet pressure sensor 3 acquire are transmitted to processor, and processor will
Pressure simulation signal is converted to the input terminal of feeding subtracter after digital signal, carries out subtraction process in subtracter and obtains pressure difference
Value, pressure difference value send processor back to by subtractor outputs in the form of digital signal, and processor is again by pressure difference value with number
The form of signal is sent into comparator input terminal, and simultaneous processor reads the dirty stifled pressure limit decision content of condenser in memory and will
The dirty stifled pressure limit decision content of condenser is sent into comparator input terminal in the form of digital signal, and comparator is to pressure difference value and cold
The dirty stifled pressure limit decision content of condenser is compared to obtain comparison result, and comparison result is by comparator output terminal with digital signal
Form sends processor back to.
If pressure difference value is greater than the dirty stifled pressure limit decision content of condenser, processor generates alarm analog signal and is sent into
Alarm module 5, the driving work alarm of alarm module 5.
Alarm module 5 is alarm lamp circuit module.
The dirty stifled pressure limit decision content of condenser is according to the different dirty stifled situation lower inlet air duct of condenser and outlet conduits
Pressure difference value statistics obtains.
The present invention includes condenser 1, inlet pressure transducer 2, outlet pressure sensor 3, control panel 4 and alarm lamp
5。
Inlet pressure transducer 2 is placed in 1 inlet conduits of condenser, and outlet pressure sensor 3 is placed on condenser 1 and goes out
In one's intention as revealed in what one says road, inlet pressure transducer 2 is connected with the signal wire of outlet pressure sensor 3 with control panel 4, the alarm of control panel 4
Signal is connected with alarm module 5.
Control panel 4 receives the pressure value signal P that inlet pressure transducer 2 is spread out ofIIt is spread out of with outlet pressure sensor 3
Pressure value signal PO, and carry out difference operation to it and show that air flows through pressure differential deltap P=P of condenserI-PO（This pressure difference is as cold
The windage of condenser）.
The Δ P under the different dirty stifled situations of condenser is counted, obtains the dirty stifled pressure limits Δ P' of condenser, and in control panel
Δ P' is configured on 4.
As Δ P<When Δ P', i.e., when practical windage is less than boundary windage, illustrate that condenser is normal, unit is run as usual.
As Δ P >=Δ P', i.e., when practical windage is greater than or equal to boundary windage, control panel 4 is issued to alarm lamp 5
Alarm signal, alarm lamp light.Illustrate that condenser is dirty stifled, is cleaned.
Δ P' can be configured according to the actual situation, be now illustrated below：
Δ P=50Pa when condenser is clean, it is dirty to block up Δ P=200Pa when obvious and serious blower operates, if Δ P' is set as
120Pa, then indicator light lights when alarming, and unit can not be shut down, when unit without clearing up when running condenser；Δ P' is such as
Fruit is set as 160Pa, then indicator light lights when alarming, compressor emergency shutdown, needs at once to clear up condenser.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
