Further, the detection value of the second sensor is acquired once every first time interval; the residual liquid value y, the first time length t, the preset first humidity difference threshold value Z0 and the difference value zi between the ith detection value of the first sensor and the ith detection value of the second sensor satisfy the relation: y ═ Σi＝1[m×(zi-Z0)×t]And m is a preset value, and i when the second duration is ended is set to be initial 0 or 1.
Another preferred scheme is that the water level of the first water outlet is equal to the water level of the second water outlet in height, and the first water outlet and the second water outlet are in switchable conduction; when the first water outlet is communicated, the second water outlet is closed; when the second water outlet is communicated, the first water outlet is closed.
Therefore, the condensed water generation speed in the dehumidification mode is high, the condensed water generation rule in the dehumidification mode is different from that in other modes, and when the ambient humidity is high, the heat exchange can be performed quickly even if no condensed water exists on the surface of the condenser, so that the electric control valve is opened when the humidity is higher than the second humidity threshold value X1, and all the condensed water generated by the evaporator is discharged out of the integrated air conditioner through the second water outlet and the external drain pipe; the method is favorable for reducing the calculation error of the multi-residual liquid value.

Detailed Description
The first embodiment of the drainage control method of the integrated air conditioner is as follows:
referring to fig. 1 and 2, the integrated air conditioner of the present embodiment includes a body, an evaporator 1, a water receiving tray 2, a condenser 3, a chassis 4 and a water pump device (not shown in the figure) mounted on the body, wherein the evaporator 1, the water receiving tray 2, the condenser 3 and the chassis 4 are distributed from top to bottom, and the water pump device is disposed on the chassis 4.
The water collector 2 has first drain 21, second drain and manger plate ring plate 22, first drain 21 is seted up at the end of a set of water collector 2, manger plate ring plate 22 is located at the end of a set of water collector 2, manger plate ring plate 22 upwards extends from the end of a set of water collector 2, first drain 21 is located the ring chamber of manger plate ring plate 22, the second drain is seted up at the lateral wall bottom of water collector 2, first drain 21 is arranged in with the condensate water in the water collector 2 to chassis 4, second drain department corresponds there is the coupling, the coupling is used for external drain 5, the setting of manger plate ring plate 22 makes the drainage water level of first drain 21 be higher than the drainage water level of second drain.
The air inlet of integral type air conditioner is equipped with the first sensor that is used for detecting ambient humidity, and second drain outlet department is equipped with the automatically controlled valve 6 that is used for controlling the second outlet and leads to closed, and automatically controlled valve 6 and first sensor communication connection.
The condensate water that produces on evaporimeter 1 surface drips on water collector 2, and when electric control valve 6 opened, the condensate water in the water collector 2 can be discharged by the second outlet to outside the external drain pipe 5 discharges to the integral type air conditioner, the condensate water in the water collector 2 can not be discharged to chassis 4 by first outlet 21 this moment.
When the electric control valve 6 is closed, the condensed water in the water receiving tray 2 cannot be discharged from the second water discharge port, and after the level of the condensed water in the water receiving tray 2 reaches the water discharge level of the first water discharge port 21, the condensed water in the water receiving tray 2 is discharged to the chassis 4 through the first water discharge port 21.
The comdenstion water that discharges to chassis 4 is sprinkled to condenser 3 surface under the effect of the device of fetching water, and the comdenstion water is discharged outside the integral type air conditioner through exhaust duct after 3 surperficial heat absorption vaporization of condenser, and 3 surfaces of fetching water to the condenser are favorable to promoting the heat transfer rate of condenser 3, and then are favorable to promoting the operating efficiency of integral type air conditioner.
Referring to fig. 3, the drainage control method of the present embodiment is applied to the integrated air conditioner of the present embodiment, and includes: step one S11, obtaining a detection value xi detected by a first sensor at the ith time, then executing step two S12, adding a value of kX (xi-X0) X t into the surplus liquid amount value to obtain an updated surplus liquid amount value Y, wherein k is a preset value, X0 is a preset first humidity threshold value (the specific setting modes of the preset value k and the first humidity threshold value X0 are shown below), then executing step three S13, judging whether the surplus liquid amount value Y is larger than the preset surplus liquid amount threshold value Y, if so, executing step four S14, controlling an electric control valve to open, executing step five S15 after waiting for a second time, controlling the electric control valve to close, and setting the current surplus liquid amount value Y to be 0; if the result of the third step S13 is no, the first step S11 is executed after waiting the first time period t.
The present embodiment completes one drainage cycle after the step five S15 is completed, and repeats the loop from the step one S11 after completing one drainage cycle.
Specifically, the second time period may be, for example, 2 minutes, and the condensed water in the water pan 2 is discharged outside the integrated air conditioner through the second water discharge port and the water discharge pipe 5 within the second time period.
Of course, when y ═ Σi＝1[k×t×(xi-X0)]When the calculation formula of the multi-residual liquid value is expressed, the value i needs to be reset to 0 or 1 after one drainage is carried out, so that the multi-residual liquid value calculation of the next drainage period can be carried out.
The excess liquid amount threshold Y of the present embodiment corresponds to the amount of water that can be held between the drain water level of the second drain port and the drain water level of the first drain port 21, and when the excess liquid amount value Y reaches the excess liquid amount threshold Y, the electronic control valve 6 is opened to perform primary drainage, and the drainage amount of the primary drainage is equal to the excess liquid amount value Y.
In the second step S12, the preset value k may be obtained according to a test, and certainly, since the multi-residual liquid value is not only related to the ambient humidity, but also related to the performance characteristics of the integrated air conditioner, it is preferable that the preset value k obtained by using the test of the integrated air conditioner of a certain model is only used in the integrated air conditioners of the same model, which is beneficial to improving the accuracy of the calculation of the multi-residual liquid value, since the actual rate of the condensed water generated by the evaporator 1 fluctuates with the changes of the parameters of the air-out wind speed of the air conditioner, the refrigeration temperature, the ambient temperature, and the like, and the preset value k set as a constant value cannot fluctuate with the changes of the air-out wind speed of the integrated air conditioner, the refrigeration temperature, and the ambient temperature, it is preferable that the preset value k is set as a function of the air-out wind speed, the refrigeration temperature, the function can also be derived from experimental and interpolation fits.
X0 is a preset first humidity threshold, when the detected value xi of the first sensor is greater than the first humidity threshold X0, it indicates that the rate of generating condensed water on the evaporator 1 is faster than the rate of vaporizing condensed water by the condenser 3, that is, when xi-X0 is greater than 0, redundant condensed water is generated, when xi-X0 is less than 0, the rate of vaporizing condensed water by the condenser 3 is faster than the rate of generating condensed water by the evaporator 1, and the first humidity threshold X0 can also be obtained through experiments; of course, in other embodiments of the present invention, the first humidity threshold X0 may also be set as a function of the outlet air speed, the cooling temperature and the ambient temperature of the integrated air conditioner, and of course, the function may also be obtained by a test and an interpolation fitting manner.
Of course, the preset value k and the first humidity threshold value X0 obtained through experiments under the specific conditions of the type, the use environment and the use habit of the integrated air conditioner can basically meet the use requirements even if the preset value k and the first humidity threshold value X0 are constant.
Alternatively, in other embodiments of the present invention, based on the consideration of the usage requirement, since it is required to ensure that the excessive amount of the condensed water does not occur in the chassis 4 as much as possible, and it is required to ensure that enough condensed water in the chassis 4 is available for the pumping device to pump water, the excessive amount of the liquid is discharged through the second drain port and the external drain pipe 5; certainly, the condition that the condensed water in the chassis 4 is not excessive is the primary requirement, and in order to better ensure that the phenomenon that the condensed water in the chassis 4 is excessive does not occur, a preset value k constant and a first humidity threshold value X0 constant corresponding to the integrated air conditioner of the type can be obtained through tests when the integrated air conditioner operates at a higher ambient temperature, a higher operating wind speed and a lower refrigeration temperature, and a surplus liquid volume value calculated by the preset value k and the first humidity threshold value X0 is higher than an actual surplus liquid volume value, so that the excessive condensed water in the chassis 4 is not easily caused even if the integrated air conditioner operates in different environments and modes during actual use, and the requirement that the condensed water in the chassis 4 is not excessive can be met; of course, this does not provide sufficient protection for the amount of condensate in the chassis 4.
The drainage control method of the embodiment ensures that the condensed water drained to the chassis 4 is not excessive and is sufficient as far as possible by controlling the drainage time of the condensed water in the water receiving tray 2; and the detection value of the first sensor controls the electronic control valve 6. Compared with the prior art, the integrated air conditioner of the embodiment does not need to be provided with a special water level detection alarm, is beneficial to reducing the number of parts, is beneficial to the simple structure of the integrated air conditioner, and is beneficial to improving the economy of the integrated air conditioner; and, because this embodiment locates electric control valve 6 on water collector 2, water collector 2's position is higher, and the process that the comdenstion water outwards discharged through external drain pipe 5 from water collector 2 is comparatively smooth and easy, is favorable to avoiding appearing the smooth problem of drainage.
The second embodiment of the drainage control method of the integrated air conditioner:
in the embodiment, the drain water level of the first drain port and the drain water level of the second drain port may also be set to be the same in height, and the first drain port and the second drain port are both provided with an electric control valve to respectively control the opening and closing of the first drain port and the second drain port; therefore, when the electric control valve of the second water outlet is closed, condensed water in the water receiving disc can be immediately discharged to the chassis through the first water outlet, the control flexibility is favorably improved, even if a preset value k and a set value and an actual value of a first humidity threshold value X0 have large deviation, even if a calculated redundant liquid volume value is obviously larger than an actual redundant liquid volume value, partial condensed water can be discharged to the chassis through the first water outlet, and the basic operation requirement of the water fetching device can be guaranteed.
Referring to fig. 4, the drainage control method of the present embodiment includes: step one S21, obtaining a detection value xi detected by the first sensor at the ith time, then executing step two S22, adding a value of kX (xi-X0) X t into the surplus liquid amount value to obtain an updated surplus liquid amount value Y, then executing step three S23, judging whether the surplus liquid amount value Y is larger than a preset liquid amount upper limit threshold value Y1, if so, executing step four S24, controlling an electric control valve of the first water discharge port to be closed and controlling an electric control valve of the second water discharge port to be opened, otherwise, executing step one S21 again after waiting for the first time length t; after the step four S24 is executed and the first time length t is waited, the step five S25 is executed, the value of kx (-X0) × t is added to the surplus liquid amount value to obtain the updated surplus liquid amount value Y, then the step six S26 is executed, whether the surplus liquid amount value Y is smaller than the preset liquid amount lower limit threshold value Y2 is judged, if yes, the step seven S27 is executed, the electric control valve of the first water discharge port is controlled to be opened, the electric control valve of the second water discharge port is controlled to be closed, otherwise, the step five S25 is executed again after the first time length t is waited.
The present embodiment completes one drainage cycle after the step seven S27 is completed, and repeats the loop from the step one S21 after completing one drainage cycle.
The upper liquid amount threshold Y1 is greater than the lower liquid amount threshold Y2, so that the amount of condensed water in the base pan 4 can be maintained between the upper liquid amount threshold Y1 and the lower liquid amount threshold Y2.
The rest of the present embodiment is the same as the first embodiment.
Third embodiment of the drainage control method of the integrated air conditioner:
the integral type air conditioner of this embodiment is provided with the second sensor that is used for detecting the air-out humidity value at the air outlet, and the detected value of first sensor and the detected value of second sensor, second sensor and 6 communication connection of electric control valve calculate the surplus liquid quantity value according to the detected value of first sensor and the detected value of second sensor.
Referring to fig. 5, the drainage control method of the present embodiment includes: step one S31, obtaining a difference value zi between a detection value detected by a first sensor at the ith time and a detection value detected by a second sensor at the ith time, then executing step two S32, adding a value of mx (zi-Z0) x t into a surplus liquid amount value to obtain an updated surplus liquid amount value Y, then executing step three S33, judging whether the surplus liquid amount value Y is larger than a preset surplus liquid amount threshold value Y, if so, executing step four S34, controlling an electric control valve to open, executing step five S35 after waiting for a second time, controlling the electric control valve to close, and setting the current surplus liquid amount value Y to be 0; if the result of the third step S33 is no, the first step S31 is executed again after waiting the first time period t.
The present embodiment completes one drainage cycle after the step five S35 is completed, and repeats the loop from the step one S31 after completing one drainage cycle.
In this embodiment, the value of m is a constant, and in other embodiments of the present invention, the value of m may also be a function of the wind outlet speed, and the function may be obtained according to a test manner.
Z0 is a preset humidity difference threshold value, and when zi-Z0 is greater than 0, the speed of generating condensed water by the evaporator 1 is represented to be greater than the speed of evaporating the condensed water by the condenser 3, namely the condensed water of the integrated air conditioner is increased at the moment; when the zi-Z0 is less than 0, the rate of generating condensed water by the evaporator 1 is represented to be less than the rate of vaporizing the condensed water by the condenser 3, namely the condensed water in the integrated air conditioner is reduced, and the humidity difference threshold Z0 can be obtained in a test mode; although the humidity difference threshold Z0 in this embodiment is a constant, in other embodiments of the present invention, the humidity difference threshold Z0 may also be a function of the wind speed of the outlet air of the integrated air conditioner, and of course, the function may also be obtained by experiments.
In the embodiment, the multi-residual liquid value is calculated according to the detection value of the first sensor and the detection value of the second sensor, so that the influence of parameters such as the refrigeration temperature and the ambient temperature of the integrated air conditioner on the multi-residual liquid value y can be eliminated, and the accuracy of the multi-residual liquid value y is improved.
The rest of the present embodiment is the same as the first embodiment.
Of course, in other embodiments of the present invention, the method for calculating the residual liquid value y in this embodiment may also be applied to the second embodiment to obtain the control method shown in fig. 6, and other parts of this embodiment are the same as the second embodiment.
The fourth embodiment of the drainage control method of the integrated air conditioner:
the integrated air conditioner of the embodiment has a dehumidification mode, and specifically, the integrated air conditioner is controlled to start the dehumidification mode when the detection value xi of the first sensor is greater than or equal to the second humidity threshold value X1.
Preferably, when the integrated air conditioner runs in the dehumidification mode, the electronic control valve 6 is controlled to be opened, the residual liquid amount value y is cleared, the electronic control valve 6 is closed when the dehumidification mode is ended, and the calculation of the residual liquid amount value y is restarted.
Referring to fig. 7, the drainage control method of the present embodiment includes: step one S41, obtaining a detection value xi detected by a first sensor at the ith time, executing step two S42, judging whether the detection value xi detected by the first sensor at the ith time is larger than or equal to a preset second humidity threshold value X1, if so, executing step three S43, judging whether the integrated air conditioner operates in a dehumidification mode, if so, executing step one S41 again after waiting for the first time period t, otherwise, executing step four S44, controlling the integrated air conditioner to start the dehumidification mode, controlling the electric control valve 6 to be opened, setting the residual liquid value y to be 0, and executing step one S41 again after waiting for the first time period t; if the execution result of the second step S42 is no, executing a fifth step S45, determining whether the integrated air conditioner is operating in the dehumidification mode, if yes, executing a sixth step S46, controlling the integrated air conditioner to close the dehumidification mode, controlling the electronic control valve 6 to close, then executing a seventh step S47, adding the value of kx (xi-X0) X t into the multi-residual liquid amount value, and obtaining an updated redundant liquid amount value y; if the execution result of the step five S45 is that the step seven S47 is not executed directly, the step eight S48 is executed after the step seven S47 is executed, whether the surplus liquid amount value Y is larger than the preset surplus liquid amount threshold value Y is judged, if yes, the step nine S49 is executed, the electronic control valve 6 is controlled to be opened, the step ten S410 is executed after waiting for the second time length, the electronic control valve 6 is controlled to be closed, and the current surplus liquid amount value Y is set to be 0; if the result of the execution of the step eight S48 is no, the step one S41 is executed again after waiting the first time period t.
The present embodiment completes one drainage cycle after the step ten S410 is completed, and repeats the loop from the step one S41 after completing one drainage cycle.
The condensate water in the dehumidification mode is generated at a high speed, the condensate water generation rule in the dehumidification mode is different from that in other modes, and when the ambient humidity is high, the condensate water can exchange heat quickly even if no condensate water exists on the surface of the condenser, so that the electric control valve is opened when the humidity is higher than a second humidity threshold value X1, and the condensate water generated by the evaporator is all discharged out of the integrated air conditioner through the second water outlet and the external drain pipe; the calculation error of the multi-residual liquid quantity value is facilitated.
Alternatively, in another embodiment of the present invention, the drain control method of the first embodiment, the second embodiment or the third embodiment may still be adopted when the integrated air conditioner operates in the dehumidification mode, and of course, in the first embodiment and the second embodiment, it is preferable that the first humidity threshold value when the integrated air conditioner operates in the dehumidification mode is smaller than the first humidity threshold value when the integrated air conditioner operates in the other mode, for example, the first humidity threshold value when the integrated air conditioner operates in the dehumidification mode is 0.5 times the first humidity threshold value when the integrated air conditioner operates in the other mode.
The other parts of this implementation are the same as those of the first embodiment.
Alternatively, in other embodiments of the present invention, the control method shown in fig. 8 can also be formed by combining the fourth embodiment with the second embodiment, and the rest of the embodiment refers to the second embodiment; and the control method as shown in fig. 9 can be formed by combining the fourth embodiment with the third embodiment, and the rest of the embodiment refers to the third embodiment.
