Embodiment
The present invention is described more fully with reference to the accompanying drawings, wherein illustrating the exemplary embodiment of the present invention.Under
The accompanying drawing that face will be combined in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, and shows
So, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the reality in the present invention
Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made all belongs to
In the scope of protection of the invention.Many descriptions are carried out to technical scheme with reference to each figure and embodiment.
Fig. 1 is the schematic flow sheet of one embodiment that based reminding method is changed according to the air-conditioning filter device of the present invention, such as
Shown in Fig. 1：
Step 101, collection indoor environment air pressure and the intraoral return air air pressure of air-conditioning return air, determine indoor environment air pressure with returning
The air pressure difference of general mood pressure.
Air-conditioning filter device can have a variety of, for example, filter screen of fine-structure mesh trellis etc., and filter screen is fixed on into air-conditioner set returns
Tuyere position.Pressure test device can be set in the outside of air-conditioner set, indoor environment atmospheric pressure value be obtained, in return air inlet for air-conditioner
Interior setting pressure test device, obtains the intraoral return air atmospheric pressure value of air-conditioning return air, the value obtained by two pressure test devices
Calculate air pressure difference, i.e. air-conditioning pressure difference.
Differential pressure pickup is a kind of sensor for being used for measuring difference between two pressure, can also pass through differential pressure pickup
Detect pressure difference change.A port in two ports of differential pressure pickup is arranged on outside air-conditioner set, another port is set
Put intraoral in air-conditioning return air, the air pressure difference of indoor environment air pressure and return air air pressure can be detected by differential pressure pickup, calculate
Draw air pressure difference.
Step 102, the inner tube temperature of collection indoor environment temperature and indoor heat exchanger, determines indoor environment temperature and interior
The temperature gap of the inner tube temperature of heat exchanger.Can be by setting temperature outside air-conditioner set and in the inner tube of indoor heat exchanger
Sensor or temperature-sensitive bag etc., the inner tube temperature for detecting indoor environment temperature and indoor heat exchanger.
Step 103, reminded and to air conditioner according to air pressure difference and temperature gap generation filter prompting message
The operation of group is correspondingly controlled.Filter prompting message can be shown with control display unit, display unit includes：Display
Shield unit, filter prompting messages such as " needing to change filter " can be shown on display screen unit.
In the above-described embodiment, can be according to ambient pressure and the pressure difference and indoor environment temperature of return air air pressure and room
The temperature difference of the inner tube temperature of interior heat exchanger judges the pollution condition of filter, generates filter prompting message and user is entered
Row is reminded, it is possible to increase the reliability and service life of air-conditioning.
In one embodiment, filter prompting message can have a variety of, including：Filter replacing prompt message,
Filter pollution level information etc..Air pressure difference threshold can be according to air-conditioning filter device type, the run time of air-conditioning
It is configured etc. parameter.Temperature gap threshold value can also be according to parameters such as type, the run times of air-conditioning of air-conditioning filter device
It is configured.
Air pressure difference threshold is obtained, judges whether air pressure difference is less than air pressure difference threshold, if not, i.e. air pressure difference is
It is no to be more than or equal to air pressure difference threshold, then control air-conditioner set to continue to run with and be based on air pressure difference generation filter pollution journey
Spend information.
If it is determined that air pressure difference is less than default air pressure difference threshold, then temperature gap threshold value is obtained, temperature difference is judged
Whether value is less than temperature gap threshold value.If it is, i.e. temperature gap is less than temperature gap threshold value, then air-conditioner set is controlled to stop fortune
Go and generate filter and change prompt message.If it is determined that temperature gap is more than or equal to temperature gap threshold value, then air-conditioning is controlled
Unit continues to run with and generates filter pollution level information.
Determining the pollution level of filter has a variety of methods, for example, based on air pressure difference and class of pollution pressure difference threshold
Value determines filter pollution level information, and generates filter pollution level information.The class of pollution have it is normal, slight, in
Degree etc., different class of pollution threshold pressure differentials are set according to the different class of pollution, be provided with first pollution grade threshold pressure differential,
Second class of pollution threshold pressure differential, the 3rd class of pollution threshold pressure differential etc..
Judge air pressure difference between first pollution degree threshold pressure differential and the second pollution level threshold pressure differential for example, working as
When, it is determined that the pollution level of filter is slight pollution, and the filter pollution level information of generation is " filter is
Slight pollution ".Different class of pollution temperature difference thresholds can also be set according to the different class of pollution, based on temperature gap and
Class of pollution temperature difference threshold determines filter pollution level information and generates filter pollution level information
In one embodiment, detection cycle is determined, is preset based on whether detection cycle cycle criterion air pressure difference is less than
Air pressure difference threshold.Detection cycle can be 15 days, i.e., judge within every 15 days whether air pressure difference is less than default air pressure difference
Threshold value, carries out cycle criterion.With the increase of air-conditioner set run time, loss and air-conditioner set based on air conditioner coolant
Each parameter sends change, can adjust the duration of detection cycle.
The cycle-index whether cycle criterion air pressure difference is less than default air pressure difference threshold is obtained, based on cycle-index
Adjust the duration of detection cycle.The duration of detection cycle is adjusted, so that the duration of detection cycle is with the increase of cycle-index
Reduce.For example, when cycle-index is 5, detection cycle is 14 days, when cycle-index is 6, detection cycle is 13 days etc..
As the increase of air-conditioner set run time is, it is necessary to adjust air pressure difference threshold so that air pressure difference threshold with
The increase of cycle-index and increase.For example, the span of air pressure difference threshold is in 10-18 handkerchiefs, with the increase of cycle-index,
Air pressure difference threshold will gradually increase, and the specific value of air pressure difference threshold can be according to air-conditioning model, cycle-index and mistake
Filter type of device etc. is configured.Temperature gap threshold value is adjusted, so that temperature gap threshold value subtracts with the increase of cycle-index
It is small.For example, the span of temperature gap threshold value is in 2-5 degree, with the increase of cycle-index, temperature gap threshold value will gradually increase
Small, the specific value of temperature gap threshold value is configured according to air-conditioning model, cycle-index and filter type etc..
