Description

Technical Field

[0001] The utility model relates to an air-conditioning cabinet, in particular to a mounting structure for the air-conditioning cabinet which can detect the life of a filter. Background Art

[0002] Central air conditioning units need to filter the air before it can be introduced into the room. There must be a large number of filters of different grades in the unit. When the unit has been running for a period of time, various dust, particles and other substances in the air will slowly be adsorbed on the filter. At this time, the filter needs to be replaced. There are currently several ways to detect whether the filter needs to be replaced. The mainstream is to set pressure ports before and after the filter and determine it through the parameters of the differential pressure gauge. However, this method has certain defects. It can only detect the use of the filter of the entire cross-section, not specific to a single filter. When replacing, either it is determined manually, which has a large inaccuracy, or all are replaced, resulting in waste. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an installation structure for an air-conditioning cabinet capable of detecting the life of a filter.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A mounting structure for detecting filter life for an air conditioning cabinet comprises a filter assembly mounted in the cabinet, the filter assembly comprising an outer frame, a plurality of inner frames arranged and mounted in the outer frame, a pressure sensor connected to a computing terminal signal mounted at each vertex of the inner frame, and a filter abutting against the pressure sensor mounted in the inner frame.

[0006] A sealing gasket is installed between two adjacent pressure sensors.

[0007] A side of the inner frame away from the air inlet is folded inward to form a retaining edge, and the sealing pad is attached to the retaining edge.

[0008] One side of the pressure sensor abuts against the retaining edge, and the other side abuts against the frame of the filter.

[0009] The beneficial effects of the utility model are as follows: the filter assembly of the utility model comprises an outer frame, a plurality of inner frames are arranged and installed inside the outer frame, pressure sensors connected to the computing terminal signal are installed at each vertex of the inner frame, a filter abutting against the pressure sensor is installed inside the inner frame, and the pressure exerted on a single filter is calculated by jointly detecting and calculating by a plurality of pressure sensors, which can ensure that a replacement reminder is issued only when dust, particles and other substances attached to the filter have reached the end of their service life, and each filter is independently detected and controlled, which can ensure the accuracy of filter replacement to the greatest extent, thereby reducing the maintenance cost of the air conditioning filter system.

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0015] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0016] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0017] Reference Figure 1-3 , an installation structure capable of detecting filter life for an air-conditioning cabinet, comprising a filter assembly 1 installed in the cabinet, the filter assembly 1 comprising an outer frame 2, a plurality of inner frames 3 arranged and installed in the outer frame 2, a pressure sensor 4 connected to a computing terminal signal installed at each vertex of the inner frame 3, a filter 5 abutting against the pressure sensor 4 installed in the inner frame 3, the pressure to which a single filter 5 is subjected is calculated and detected by a plurality of pressure sensors, which can ensure that a replacement reminder is issued only when dust, particles and other substances attached to the filter have reached the end of their service life, and each filter is independently detected and controlled, which can ensure the accuracy of filter replacement to the greatest extent, thereby reducing the maintenance cost of the air-conditioning filter system.

[0018] A sealing pad 6 is installed between two adjacent pressure sensors 4 to ensure that air can only pass through the filter 5, thereby preventing external air from entering the internal environment without being filtered.

[0019] A side of the inner frame 3 away from the air inlet is folded inward to form a retaining edge 7 , and the sealing gasket 6 is attached to the retaining edge 7 .

[0020] One side of the pressure sensor 4 abuts against the retaining edge 7 , and the other side abuts against the frame of the filter 5 .

[0021] How this product works:

[0022] 1. Debugging stage:

[0023] After the new filter 5 is installed, start the equipment and adjust the wind speed of the central air conditioner. At this time, save the pressure detected by the pressure sensor 4 at different wind speeds, and use it as the reference pressure at each wind speed. At this time, replace the filter that is about to fail, start the equipment again, and adjust the wind speed of the central air conditioner. At this time, save the pressure detected by the pressure sensor 4 at different wind speeds, and use it as the failure pressure at each wind speed (this process can be operated in the laboratory, that is, when installing the central air conditioner, directly input the reference pressure and failure pressure at each wind speed into the calculation terminal).

[0024] 2. Use stage:

[0025] After the new filter 5 is installed, it can be started normally. During use, the pressure detected by the pressure sensor 4 gradually increases, which proves that dust, particles and other substances begin to adhere to the filter 5. When the pressure detected by the pressure sensor 4 increases to the failure pressure, it proves that the filter 5 has reached the end of its service life. At this time, the computing terminal will send a signal to remind the maintenance personnel to replace it and inform the specific location. If the pressure detected by the pressure sensor 4 drops suddenly, it can be seen that the filter 5 is physically damaged, such as perforated. At this time, the computing terminal will send a signal to remind the maintenance personnel to replace it and inform the specific location.

[0026] During use, when the wind speed is adjusted, the reference pressure and failure pressure of the pressure sensor 4 will be dynamically adjusted accordingly.

[0027] This application is only for structural improvements. How to achieve balance between all the pressure sensors 4 on the same filter 5, as well as the calculation of reference pressure and failure pressure, dynamic adjustment and other procedural technologies are not the patent focus of this application.
