The specific embodiment
Core of the present invention is to provide a kind of cleaning based reminding method of air conditioner filter, and manpower and materials when the method can be alleviated cleaning filter are wasted, and guarantee the heat exchange efficiency of air-conditioner simultaneously.Another core of the present invention is to provide a kind of cleaning alarm set of air conditioner filter.
In order to make those skilled in the art understand better technical scheme provided by the invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The cleaning based reminding method of the air conditioner filter that as shown in Figure 1, the embodiment of the present invention provides comprises the following steps:
EAT and the leaving air temp of S12, collection indoor set, and calculate the difference between this EAT and this leaving air temp;
S14, judge whether the difference between above-mentioned EAT and leaving air temp is greater than temperature difference preset value;
S15, when the difference between EAT and leaving air temp is greater than temperature difference preset value, the aperture of detected electrons expansion valve;
S16, while heating, judge whether the aperture of electric expansion valve is greater than the first aperture preset value, during refrigeration, judge whether the aperture of electric expansion valve is less than the second aperture preset value;
S17, when heating, the aperture of electric expansion valve is greater than the first aperture preset value, or the aperture of electric expansion valve is less than the second aperture preset value alarm during refrigeration.
In above-mentioned steps, when the EAT of indoor set and the difference of leaving air temp are less than or equal to temperature difference preset value, this based reminding method can finish, until new enabling signal is sent.Similarly, when heating, the aperture of electric expansion valve is less than or equal to the first aperture preset value, or when refrigeration electric expansion valve aperture while being more than or equal to the second aperture preset value, this based reminding method also can finish, until new enabling signal is sent.
Understandably: during refrigeration, after filter is contaminated, the air throughput of whole filter will reduce, and pass through the air of filter and measure after larger heat transferring medium heat exchange, air cooling-down amplitude is larger, therefore the difference between EAT and leaving air temp will increase, and electric expansion valve can detect the demand minimizing of heat transferring medium, and electric expansion valve will close to less aperture; While heating, after filter is contaminated, the air throughput of whole filter will reduce, and pass through the air of filter and measure after larger heat transferring medium heat exchange, atmosphere temperature rising amplitude is larger, therefore the difference between EAT and leaving air temp will increase, and electric expansion valve can detect the demand increase of heat transferring medium, and electric expansion valve will be opened to larger aperture.
Above-mentioned temperature difference preset value, the first aperture preset value and the second aperture preset value are generally preset in control section, and three's size is specifically determined according to the applied environment of air-conditioner and heat exchange demand, herein this is not restricted.
Known by foregoing description, the cleaning based reminding method of the air conditioner filter that the embodiment of the present invention provides, by the difference between the EAT of indoor set and leaving air temp, and the detection of the aperture of electric expansion valve, the pollution condition of judgement filter, only when the pollution condition of filter is more serious, send alarm signal, to clear up filter.Obviously, than the content of introducing in background technology, above-mentioned cleaning based reminding method can be cleared up according to the real work situation of filter, and then alleviates the waste of the manpower and materials that regularly cleaning brings, can clear up timely filter, guarantee the heat exchange efficiency of air-conditioner simultaneously.
Further in technical scheme, in the cleaning based reminding method that the embodiment of the present invention provides, further comprising the steps of before step S12:
S11, acquisition system running parameter, judge whether normal operation of air-conditioner system according to system operational parameters, when air-conditioner system normal operation, and execution step S12.
Said system running parameter is the parameter that characterizes air-conditioner system operation conditions, specifically can be the system pressure of air-conditioner system, delivery temperature of compressor etc., whether normally the delivery temperature of optimum decision system pressure of the present invention, compressor, as system operational parameters, improves the evaluation system accuracy of operation with this.
The cleaning based reminding method for example the technical program being provided below describes.
Example one: when air-conditioner system is in 35 ℃ of situations of environment temperature during running refrigerating, air-conditioner system can make the following judgment:
1, first judge that whether running situation is normal: under normal circumstances, during 35 ℃ of environment temperatures, system high pressure is in 30kgf left and right, system low-voltage is in 8kgf left and right, the delivery temperature of compressor is upper and lower at 80 ℃, if the running parameter of system this zone of reasonableness (system high pressure scope is 30 ± 5kgf, preferably, 30 ± 3kgf; System low-voltage scope is 8 ± 2kgf, preferably 8 ± 1kgf; Delivery temperature scope is 80 ± 15 ℃, preferably, and 80 ± 10 ℃) in, can judge air-conditioner system normal operation;
Secondly 2, according to the EAT of indoor set and the leaving air temp judgement indoor set heat exchange situation that combines: lighter in filter pollution condition, while not needing to clear up, filter is lighter for the impact of indoor set air quantity, heat exchange efficiency is higher, the difference of leaving air temp and EAT is in zone of reasonableness, this zone of reasonableness is assumed to 15 ± 7 ℃, preferably 15 ± 3 ℃; If filter pollution condition is heavier, in the time of need to clearing up, filter is comparatively obvious for the impact of indoor set air quantity, heat exchange efficiency declines, leaving air temp reduces, and therefore, when the difference of leaving air temp and EAT is increased to while being greater than 25 ℃, illustrates that filter is dirtier;
3, then in conjunction with the aperture judgement of electric expansion valve: when, indoor set heat exchange clean at filter is all right, indoor set electric expansion valve can play the effect of suitable control heat transferring medium flow, the aperture of electric expansion valve maintains 200～300 pulses, if filter damage ratio is more serious, indoor set reduction of heat exchange efficiency, indoor-unit cooling-medium amount demand reduces, and electric expansion valve can turn down less aperture;
If 4 systems detect the air-conditioner system of normal operation and satisfy condition 2 and condition 3 simultaneously, think that filter damage ratio is more serious, report to the police, then clear up filter.
Example two: when air-conditioner system moves while heating in 7 ℃ of situations of environment temperature, air-conditioner system can make the following judgment:
1, first judge that whether running situation is normal: under normal circumstances, during 7 ℃ of environment temperatures, system high pressure is in 26kgf left and right, system low-voltage is in 7kgf left and right, the delivery temperature of compressor is upper and lower at 70 ℃, if the running parameter of system this zone of reasonableness (system high pressure scope is 26 ± 5kgf, preferably, 26 ± 3kgf; System low-voltage scope is 7 ± 2kgf, preferably, and 7 ± 1kgf; The delivery temperature scope of compressor is 70 ± 15 ℃, preferably, 70 ± 10 ℃) in, can decision-making system running status normal;
Secondly 2, according to the EAT of indoor set and the leaving air temp judgement indoor set heat exchange situation that combines: lighter in filter pollution condition, while not needing to clear up, filter is lighter for the impact of indoor set air quantity, heat exchange efficiency is higher, the difference of leaving air temp and EAT is in zone of reasonableness, this zone of reasonableness is assumed to 18 ± 7 ℃, preferably 18 ± 3 ℃; If filter pollution condition is heavier, in the time of need to clearing up, filter is comparatively obvious for the impact of indoor set air quantity, heat exchange efficiency declines, leaving air temp raises, and therefore, when the difference of leaving air temp and EAT is increased to while being greater than 28 ℃, illustrates that filter is dirtier;
3, then need to judge in conjunction with indoor set electronic expansion valve opening: when, indoor set heat exchange clean at filter is all right, electric expansion valve can play the effect of suitable control heat transferring medium flow, the aperture of electric expansion valve is in 250～350 pulses, if filter damage ratio is more serious, when indoor set heat exchange reduces, the increase in demand of indoor-unit cooling-medium amount, electric expansion valve can be held large to larger aperture;
If 4 systems detect the air-conditioner system of normal operation and satisfy condition 2 and condition 3 simultaneously, judge that filter damage ratio is more serious, report to the police, then clear up filter.
Technique scheme is by the detection to the aperture of the difference of the EAT of the ruuning situation of system, indoor set and leaving air temp and electric expansion valve, comparatively accurately comprehensively after judgement, just drawing the conclusion of whether clearing up filter, obviously, this technical scheme has improved the accuracy of the cleaning prompting of filter.
Further, in technical scheme, in step S11, if air-conditioning system operation is undesired, enter following steps:
S13, send system maintenance alerting signal.
That is, when system, move when undesired, in-problem parts in system are keeped in repair, to guarantee the normal operation of system.
In order to guarantee better the heat exchange of air-conditioner, in above-mentioned steps S14, when the EAT of indoor set and the difference of leaving air temp are less than or equal to temperature difference preset value, return to step S12, more preferably, can return to step S11.Particularly, above-mentioned condition can be returned to corresponding steps after meeting after predetermined period.Obviously, this technical scheme can be carried out cycle detection to air-conditioner system, with this, achieves the above object.
In like manner, in step S3, when heating, the aperture of electric expansion valve is less than or equal to the first aperture preset value, or when refrigeration electric expansion valve aperture while being more than or equal to the second aperture preset value, return to step S12, more preferably, can return to step S11.
