Description
Technical field
The utility model relates to central air conditioner system, relates in particular to air-conditioning box and terminal supply air system that central air conditioner system is concentrated air-supply.
Background technology
Central air conditioning equipment is very general in the application in fields such as modern industry, civilian, commerce, and central air conditioner system commonly used comprises the air-conditioning unit, carries energy conduit, water pump and do not hold supply air system etc.Wherein, terminal supply air system can be according to Various Seasonal and user's needs, heat energy or cold energy being delivered to each required area of space by surface cooler in the mode of air-supply, make this zone can reach office or the required suitable temperature of producing, live, is important step in the central air conditioner system.
Terminal supply air system is made up of blower fan, surface cooler, screen pack, terminal air outlet and dew tapping equipment etc.Each terminal air outlet all is equipped with screen pack, when the screen pack of certain air outlet is stopped up by dust, the air quantity that blower fan can provide will be obviously not enough, thereby influencing central air conditioner system controls the temperature in the regional area, have a strong impact on refrigeration or heating efficiency, because the power of pressure fan is constant at this moment, can cause energy waste simultaneously.At this situation, what generally take at present is the measure of patrolling on schedule, regularly cleaning, and is that waste of manpower also consumes material resources like this, has increased the operation cost of equipment; In addition, the filtering net cleaning degree of zones of different exists than big-difference, and regularly the mode of cleaning lacks specific aim, may cause great amount of water resources and waste of electric energy when cleaning.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of checkout gear that can detect the screen pack cleanliness factor automatically, can report to the police automatically when the screen pack cleanliness factor is reduced to a certain degree.
The utility model is achieved through the following technical solutions:
A kind of screen pack cleanliness factor checkout gear is characterized in that:
Described checkout gear comprises fan blade, by the microgenerator that fan blade drives, the output circuit of microgenerator is connected with alarm by starting switch;
Offer installing hole on the screen pack, the inside dimension of installing hole and the exterior contour of fan blade are measure-alike, and the fan blade wheel shaft after the installation is vertical with screen pack.
The utility model is by installing warning device on screen pack, utilize the leeway of screen pack front and back end to detect the stopping state of screen pack; Promote fan blade by leeway and drive the microgenerator generating, the electric energy that utilizes microgenerator to produce starts warning device.
Fan blade is fixed on the screen pack, and the fan blade wheel shaft after the installation is vertical with screen pack, when screen pack is unobstructed, the blast of each point is equal substantially before and after the screen pack, and this moment, motor speed was comparatively constant, and the electromotive force that microgenerator produced is less, starting switch is started, and alarm is not worked; Dirty when stifled when screen pack, the turnover blast can increase faster rotational speed before and after the fan blade, the induced electromotive force that microgenerator produces increases thereupon, when the rotating speed of fan blade reached setting value, the voltage that microgenerator produces can make starting switch open, and alarm gets electric back and reports to the police.The warning form can be multiple warning forms such as audible alarm and/or luminous warning.
Further, alarm can be linked to each other with central control system DCS by signal transmission line, when alarm starts, central control system DCS obtains a signal, be convenient to the clean-up performance that long-range attendant in time grasps screen pack on each air outlet, change unclean screen pack or cleaning and filtering net.
Further again, can pass through following circuit, when the fan blade rotating speed reaches the setting tachometer value, realize the automatic warning of alarm:
Described alarm comprises buzzer and light-emitting component,
Starting switch comprises triode Q1, triode Q2,
Be in series with resistance R 01, R02, R06 on the output circuit of microgenerator,
Rectifier cell D1 is in parallel with output circuit,
After the emitter stage of buzzer D2 and triode Q1 joins, in parallel by the colelctor electrode of triode Q1, by in parallel with resistance R 01 behind the base stage series resistor R03 of triode with output circuit,
After the emitter stage of light-emitting component and triode Q2 joins, in parallel by the colelctor electrode of triode Q2, by in parallel with resistance R 01 behind the base stage series resistor R04 of triode with output circuit.
When screen pack was unobstructed, the electromotive force that microgenerator produced was less, can't drive triode Q1, triode Q2, and this moment, buzzer and light-emitting component must not; Screen pack is dirty when stifled, the turnover blast can increase before and after the motor, when the rotating speed of fan blade reached setting value, the voltage that the induced electromotive force that microgenerator provided produces can drive triode Q1, triode Q2 conducting, made buzzer and light-emitting component get electric and warning.
Light-emitting component can be the similar versions such as high resistance measurement R05 of light emitting diode D3 and series connection with it.
Further again, consider that different occasions is not quite similar to the requirement of screen pack cleanliness factor, therefore need the warning start-up point of setting also different, can be variable resistor with resistance R 06, when needs change the entry condition of starting switch, only need to change the resistance of variable resistor R06, can realize difference warning critical point setting at different cleanliness factor requirements.
The utility model can use in all kinds of big-and-middle-sized air conditioner ventilating systems, exhaust system and VMC, and its beneficial effect is:
1. need not the special messenger and patrol on schedule, regularly clean the terminal air outlet screen pack of air-conditioning system, can save great amount of manpower and material resources;
2. regional temperature control effect can promote greatly, thus prolong equipment such as blower fan in the central air conditioner system service life, reduce fault rate, improve service efficiency, improve the management of equipment;
The energy that whole unit is made, maximized obtaining brought into play, and systemic-function is further perfect;
4. with low cost, easy for installation, practical, dispense with outer connecting power provides electric energy for alarm, good energy-conserving effect.
