Abstract
The utility model discloses an air conditioning filter screen intelligent alarm device, which comprises an intelligent control device and two pressure sensors, wherein the two pressure sensors are respectively arranged on the two sides of an air conditioning filter screen, the inner portion of the intelligent control device is provided with a pressure difference transmitter and a control circuit board, the outer portion is provided with an acousto-optic alarm device and a state indicator light, the two pressure sensors are respectively connected with the pressure difference transmitter through circuits, and the control circuit board and the pressure difference transmitter, the acousto-optic alarm device and the state indicator are connected through the circuits. The air conditioning filter screen intelligent alarm device can judge state of the filter screen according to the pressure difference on the two sides of the filter screen, and sends out corresponding state indication and alarm.
Description
Technical field
The utility model relates to a kind of filter screen monitoring device, is applicable to various blower fan filter screens, is particularly useful for the monitoring of central air conditioner filter screen blocked state.
Background technology
Filter screen in the air-conditioning unit because of dust in the air or the obstruction of other impurity, causes the not enough phenomenon of air quantity in use for some time, need monitor its state, if stop up to a certain degree, then needs to unpick and wash or change.Air conditioner filter screen generally is installed in airtight space, and the personnel that generally need repairing often pull down filter screen and check, whole process bothers very much, the waste great amount of manpower, and omission often appears, influence the effect of air-conditioning.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can carry out self check to filter network state, solves the defective that wastes time and energy by manual detection at present, monitors and show the situation of filter screen in real time, uses manpower and material resources sparingly, and increases work efficiency.
A kind of air conditioner filter screen intelligent alarm device, it is characterized in that: described device comprises an intelligence controlling device, two pressure transducers with the both sides that are separately positioned on air conditioner filter screen, described intelligence controlling device inside is provided with pressure difference transmitter, control circuit board, the outside is provided with acoustic-optic alarm and status indicator lamp, described two pressure transducers connect described pressure difference transmitter by circuit respectively, and described control circuit board is connected by circuit with described pressure difference transmitter, acoustic-optic alarm and status indicator lamp.
The utility model is by being installed in the pressure transducer of filter screen front and back, intellectual analysis is the pressure differential of filter screen front and back air relatively, after pressure differential surpasses setting value, differential pressure transmitter is transferred to control circuit board with alerting signal, control circuit board is connected alarm display lamp, and this device can send alarm sound simultaneously, and the expression filter screen stops up, need to clean or change, with the alert emergency processing.This device is widely used in various blower fan filter screens, as central air conditioner fan coil filter screen, assembled air-conditioner unit filter screen, cleaner filter screen etc., can monitor the filter screen situation in real time, with screen pack resistance drop control zone of reasonableness, improve running efficiency of system, make things convenient for equipment operation management, increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
As shown in Figure 1, the utility model comprises an intelligence controlling device 1, two pressure transducers 3 with the both sides that are separately positioned on air conditioner filter screen 2 are provided with pressure difference transmitter, control circuit board in the described intelligence controlling device 1, and the outside is provided with acoustic-optic alarm 11 and status indicator lamp 12.Described two pressure transducers 3 connect described pressure difference transmitter by circuit respectively, and described control circuit board is connected by circuit with described pressure difference transmitter, acoustic-optic alarm, status indicator lamp.
During the utility model work, two pressure transducers are sent to pressure difference transmitter with the air pressure signal of gathering respectively, analyze the relatively pressure differential of filter screen front and back air, and when pressure differential was in normal value, the normal condition pilot lamp on the intelligence controlling device was long bright; After pressure differential surpasses setting value, differential pressure transmitter is transferred to control circuit board with alerting signal, control circuit board will be connected alarm lamp, connect acoustic-optic alarm simultaneously, flicker alarm lamp or hummer send alarm sound, the expression filter screen stops up, and the alert filter screen stops up, and needs to clean or change.
