Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
It should be noted that, in the control method of the humidifier of machine room air conditioner of the embodiment of the present invention, heater can be electric heater.
Fig. 1 is the flow chart of the control method of humidifier of machine room air conditioner according to an embodiment of the invention, and Fig. 2 is the flow chart of the control method of humidifier of machine room air conditioner according to the present invention's specific embodiment.
As shown in Figure 1 with shown in Fig. 2, the control method of the humidifier of machine room air conditioner of the embodiment of the present invention, comprises the following steps:
S101, obtains the water temperature value in humidifier water tank, and obtains ambient humidity value.
Fig. 3 is the structural representation according to an embodiment of the invention in humidifier water tank, as shown in Figure 3, the humidifier water tank of the embodiment of the present invention, comprise water tank, spilling water water level and low-water level switch, cooling-water temperature sensor, heater, heater temperature controller, solid-state relay, water inlet pipe, drainpipe, and the water intaking valve be separately positioned on water inlet pipe and drainpipe and draining valve.
According to one embodiment of present invention, detect the water temperature in humidifier water tank in real time by cooling-water temperature sensor, and by repeated detection in a period of time to water temperature carry out filtering and be averaging process, obtain the water temperature value (S201) in humidifier water tank; By the real-time testing environment humidity of humidity sensor, and by repeated detection to ambient humidity carry out filtering and be averaging process, obtain ambient humidity value (S202).
S102, environmentally humidity value and user set humidity value and generate humidification demand.
Particularly, in one embodiment of the invention, by following formulae discovery humidification demand:
Q＝(Hs-H1)/q*100％ (1)
Wherein, Q is humidification demand, and Hs sets humidity value for user, and H1 is ambient humidity value, and q is humid control deviate.
In one embodiment of the invention, user sets humidity value Hs can in advance according to the requirements set of user, humid control deviate q can be set simultaneously, namely set humidity value and the maximum deviation of ambient humidity value, wherein, it is the default value that humidifier is arranged in advance that humid control deviate q can be, and also can be the value that user is set according to demand.After the above-mentioned numerical value of acquisition, the value of humidification demand Q can be calculated according to formula (1).Then, according to the value of the humidification demand Q of calculating gained, humidification demand (S203) can be determined whether.Particularly, when Q is more than or equal to predetermined threshold value, be judged as humidification demand; When Q is less than predetermined threshold value, be judged as without humidification demand.Be understandable that, when ambient humidity value is less than the humidity value of user's setting and the two difference is larger, needs to carry out humidification, namely have humidification demand; When ambient humidity value is more than or equal to the humidity value of user's setting, or when the two is more or less the same, do not need to carry out humidification, namely without humidification demand.
S103, according to humidification demand and water temperature value, the heater to humidifier of machine room air conditioner controls.
When being judged as in step S102 without humidification demand, if water temperature value is more than or equal to water temperature retention value, then close heater; If water temperature value is less than water temperature retention value, then calculate the power output of heater according to water temperature retention value and water temperature value.For example, water temperature retention value can be set to 30 DEG C, particularly, can judge whether water temperature value is more than or equal to 30 DEG C (S204), when water temperature value is more than or equal to 30 DEG C, perform S205, otherwise perform S206.Wherein, water temperature retention value is greater than environment temperature, and when water temperature is equal to or slightly greater than water temperature retention value, water tank can not export steam significantly.
More specifically, in one embodiment of the invention, by the power output of following formulae discovery heater:
P1＝(Tm-Tw)/p*100％ (2)
Wherein, P1 is the power output of heater, and Tw is water temperature value, and Tm is water temperature retention value, and p is that water temperature keeps deviate.
In one embodiment of the invention, water temperature retention value Tm can be preset, and set water temperature keeps deviate p, namely set water temperature retention value and the maximum deviation of water temperature value, such as, can be 3 DEG C, wherein, it is the default value that humidifier is arranged in advance that water temperature keeps deviate p can be, and also can be the value that user is set according to demand.As step S206, when water temperature value is less than 30 DEG C, can heater.After the above-mentioned numerical value of acquisition, the power output P1 of heater can be calculated according to formula (2).Wherein, P1 is percentage, and actual output power value can obtain according to this percentage calculation.Be understandable that, when P1 is more than or equal to 100%, water temperature value differs comparatively large with water temperature retention value, can control heater with capacity operation, thus make water temperature meet or exceed water temperature retention value as early as possible.
Thus, when without humidification demand, water temperature can be made to remain on more than default water temperature retention value, thus when there being humidification demand, rapidly water temperature can be brought up to default temperature value.For example, if environment temperature is 22 DEG C, when without humidification demand, water temperature can remain on about 22 DEG C, and in one embodiment of the invention, controlling water temperature remains on about 30 DEG C.When there being humidification demand, if need water temperature to be increased to 90 DEG C, it is shorter to heat the used time heating is compared from water temperature when being so about 30 DEG C from water temperature when being 22 DEG C, thus can adjust ambient humidity more quickly.
When being judged as humidification demand in step S102, if water temperature value is more than or equal to high water temperature value, then set the power output of humidity value and ambient humidity calculating heater according to user; If water temperature value is less than high water temperature value, then control heater is with capacity operation.Wherein, when water temperature reaches high water temperature value, can ensure that the amount of the steam that water tank exports can meet the primary demand of humidification function.
For example, high water temperature value can be 95 DEG C, particularly, can judge whether water temperature value is more than or equal to 95 DEG C (S207), if water temperature is less than 95 DEG C, then performs S208, otherwise, perform S209.Wherein, step S208 improves the process of water temperature, and step S209 is the concrete humidification of water temperature when reaching the primary demand that can meet humidification function.When water temperature value is more than or equal to 95 DEG C once, then record this action.Continue to obtain ambient humidity value in the process that step S209 performs, and determine whether humidification demand accordingly.If be judged as humidification demand in this course always, then continue to perform S209, having should be appreciated that when have recorded this action, even if water temperature value is lower than 95 DEG C, still performing step S209.If be judged as without humidification demand in the process that step S209 performs, then stop performing step S209, and recorded action is removed, should be appreciated that after removing recorded action, if be again judged as humidification demand, and when water temperature value is lower than 95 DEG C, can step S208 be performed.
Wherein, by the power output of heater in following formulae discovery step S209:
P2＝(Hs-H1)/q*100％ (3)
Wherein, P2 is the power output of heater, and Hs is that described user sets humidity value, and H1 is described ambient humidity value, and q is humid control deviate.
In one embodiment of the invention, in advance according to the requirements set humidity value of user, and can set humid control deviate, namely set humidity value and the maximum deviation of ambient humidity value, such as, can be 2%RH.As step S209, when water temperature is more than or equal to 95 DEG C, can heater.After the above-mentioned numerical value of acquisition, the power output P2 of heater can be calculated according to formula (3).Wherein, P2 is percentage, and actual output power value can obtain according to this percentage calculation.Be understandable that, when P2 is more than or equal to 100%, ambient humidity value and user set humidity value and differ larger, can control heater with capacity operation, thus, water temperature can be improved fast, make water tank in air, export steam rapidly, thus improve ambient humidity rapidly.When P2 is less than 100%, ambient humidity value and user set humidity value and differ less, can control heater with less Power operation, thus, slowly can improve ambient humidity, thus improve the control accuracy to ambient humidity.
In addition, in one embodiment of the invention, the power of heater is regulated to realize by solid-state relay, such as, the solid-state relay of certain model, the direct-current control voltage U of input
dCfor 0-10V, the corresponding alternating voltage U exported
aCfor 0-220V, its computing formula is: U
aC=(4840U
dC) ^0.5.The concrete corresponding relation of the DC voltage of input and the alternating voltage of output is as shown in table 1.
| U DC/V | U AC/V |
| 0 | 0 |

Table 1
As shown in Table 1, the DC voltage of this solid-state relay input is less and alternating voltage that is that export is comparatively large, thus drives larger load by small control signal.
According to the control method of the humidifier of machine room air conditioner of the embodiment of the present invention, environmentally humidity value and user set humidity value and generate humidification demand, and according to humidification demand and water temperature value, the heater to humidifier of machine room air conditioner controls, thus, humidifier can be made to export steam rapidly when starting humidification, can Quick height ambient humidity.In addition, in humidification, environmentally humidity can adjust the power output of heater, thus the control accuracy to ambient humidity can be improved, simultaneously can economize energy.
For realizing the control method of the humidifier of machine room air conditioner of above-described embodiment, the present invention also proposes a kind of humidifier of machine room air conditioner.
Fig. 4 is the structured flowchart of humidifier of machine room air conditioner according to an embodiment of the invention.
As shown in Figure 4, the humidifier of machine room air conditioner of the embodiment of the present invention, comprising: acquisition module 10, generation module 20 and control module 30.
Wherein, acquisition module 10 for obtaining the water temperature value in humidifier water tank, and obtains ambient humidity value.
Particularly, acquisition module 10 can detect the water temperature in humidifier water tank in real time, and by repeated detection to water temperature carry out filtering and be averaging process, obtain the water temperature value in humidifier water tank; Can testing environment humidity in real time, and by repeated detection to ambient humidity carry out filtering and be averaging process, obtain ambient humidity value.
Generation module 20 is for environmentally humidity value and user set humidity value generation humidification demand.
Particularly, in one embodiment of the invention, generation module 20 is by following formulae discovery humidification demand:
Q＝(Hs-H1)/q*100％ (1)
Wherein, Q is humidification demand, and Hs sets humidity value for user, and H1 is ambient humidity value, and q is humid control deviate.
In one embodiment of the invention, user sets humidity value Hs can in advance according to the requirements set of user, humid control deviate q can be set simultaneously, namely set humidity value and the maximum deviation of ambient humidity value, wherein, it is the default value that humidifier is arranged in advance that humid control deviate q can be, and also can be the value that user is set according to demand.After the above-mentioned numerical value of acquisition, generation module 20 can calculate the value of humidification demand Q according to formula (1).When Q is more than or equal to predetermined threshold value, generation module 20 has been judged as humidification demand; When Q is less than predetermined threshold value, generation module 20 is judged as without humidification demand.Be understandable that, when ambient humidity value is less than the humidity value of user's setting and the two difference is larger, needs to carry out humidification, namely have humidification demand; When ambient humidity value is more than or equal to the humidity value of user's setting, or when the two is more or less the same, do not need to carry out humidification, namely without humidification demand.
Control module 30 is for according to humidification demand and water temperature value, the heater to humidifier of machine room air conditioner controls.
When being judged as without humidification demand, if water temperature value is more than or equal to water temperature retention value, then close heater; If water temperature value is less than water temperature retention value, then control module 30 calculates the power output of heater according to water temperature retention value and water temperature value.Wherein, water temperature retention value is greater than environment temperature, and when water temperature is equal to or slightly greater than water temperature retention value, water tank can not export steam significantly.
Particularly, in one embodiment of the invention, control module 30 is by the power output of following formulae discovery heater:
P1＝(Tm-Tw)/p*100％ (2)
Wherein, P1 is the power output of heater, and Tw is water temperature value, and Tm is water temperature retention value, and p is that water temperature keeps deviate.
In one embodiment of the invention, water temperature retention value Tm can be preset, and set water temperature keeps deviate p, namely set water temperature retention value and the maximum deviation of water temperature value, such as, can be 3 DEG C, wherein, it is the default value that humidifier is arranged in advance that water temperature keeps deviate p can be, and also can be the value that user is set according to demand.After the above-mentioned numerical value of acquisition, control module 30 can calculate the power output P1 of heater according to formula (2).Wherein, P1 is percentage, and actual output power value can obtain according to this percentage calculation.Be understandable that, when P1 is more than or equal to 100%, water temperature value differs comparatively large with water temperature retention value, control module 30 can control heater with capacity operation, thus make water temperature meet or exceed water temperature retention value as early as possible.
Thus, when without humidification demand, water temperature can be made to remain on more than default water temperature retention value, thus when there being humidification demand, rapidly water temperature can be brought up to default temperature value.For example, if environment temperature is 22 DEG C, when without humidification demand, water temperature can remain on about 22 DEG C, and in one embodiment of the invention, controlling water temperature remains on about 30 DEG C.When there being humidification demand, if need water temperature to be increased to 90 DEG C, it is shorter to heat the used time heating is compared from water temperature when being so about 30 DEG C from water temperature when being 22 DEG C, thus can adjust ambient humidity more quickly.
When being judged as humidification demand, if water temperature value is more than or equal to high water temperature value, then control module 30 sets the power output of humidity value and ambient humidity calculating heater according to user; If water temperature value is less than high water temperature value, then control module 30 control heater is with capacity operation.Wherein, when water temperature reaches high water temperature value, can ensure that the amount of the steam that water tank exports can meet the primary demand of humidification function.
For example, high water temperature value can be 95 DEG C, particularly, can judge whether water temperature value is more than or equal to 95 DEG C, if water temperature is less than 95 DEG C, then control heater is with capacity operation, otherwise, the power output of humidity value and ambient humidity calculating heater is set according to user.Wherein, control heater take capacity operation as the process improving water temperature, set according to user the power output that humidity value and ambient humidity calculate heater, and control heater with calculated Power operation for concrete humidification when water temperature reaches the primary demand that can meet humidification function.When water temperature value is more than or equal to 95 DEG C once, then record this action.Continue to obtain ambient humidity value in control heater is with calculated Power operation process, and determine whether humidification demand accordingly.If be judged as humidification demand in this course always, then continue control heater with calculated Power operation, should be appreciated that when have recorded this action, even if water temperature value is lower than 95 DEG C, still control heater is with calculated Power operation.If be judged as in control heater is with the process of calculated Power operation without humidification demand, then control heater is out of service, and recorded action is removed, be to be understood that, after removing recorded action, if be again judged as humidification demand, and when water temperature value is lower than 95 DEG C, can control heater with capacity operation.
Particularly, if water temperature value is more than or equal to high water temperature value, control module 30 is by the power output of following formulae discovery heater:
P2＝(Hs-H1)/q*100％ (3)
Wherein, P2 is the power output of heater, and Hs is that described user sets humidity value, and H1 is described ambient humidity value, and q is humid control deviate.
In one embodiment of the invention, in advance according to the requirements set humidity value of user, and can set humid control deviate, namely set humidity value and the maximum deviation of ambient humidity value, such as, can be 2%RH.After the above-mentioned numerical value of acquisition, control module 30 can calculate the power output P2 of heater according to formula (3).Wherein, P2 is percentage, and actual output power value can obtain according to this percentage calculation.Be understandable that, when P2 is more than or equal to 100%, ambient humidity value and user set humidity value and differ larger, control module 30 can control heater with capacity operation, thus, water temperature can be improved fast, make water tank in air, export steam rapidly, thus improve ambient humidity rapidly.When P2 is less than 100%, ambient humidity value and user set humidity value and differ less, control module 30 can control heater with less Power operation, thus, slowly can improve ambient humidity, thus improve the control accuracy to ambient humidity.
In addition, in one embodiment of the invention, the power of heater is regulated to realize by solid-state relay, such as, the solid-state relay of certain model, the direct-current control voltage U of input
dCfor 0-10V, the corresponding alternating voltage U exported
aCfor 0-220V, its computing formula is: U
aC=(4840U
dC) ^0.5.The concrete corresponding relation of the DC voltage of input and the alternating voltage of output is as shown in table 1.As shown in Table 1, the DC voltage of this solid-state relay input is less and alternating voltage that is that export is comparatively large, thus drives larger load by small control signal.
According to the humidifier of machine room air conditioner of the embodiment of the present invention, environmentally humidity value and user can set humidity value generation humidification demand, and according to humidification demand and water temperature value, heater be controlled, thus, steam can be exported rapidly when starting humidification, can Quick height ambient humidity.In addition, in humidification, environmentally humidity can adjust the power output of heater, thus the control accuracy to ambient humidity can be improved, simultaneously can economize energy.
