In the embodiment of the disclosure, the indoor evaporator of the air conditioner comprises two or more parallel flow paths, and each flow path is provided with a corresponding electromagnetic valve for controlling the refrigerant flow, so that the refrigerant flow in the evaporator of the corresponding flow path can be adjusted by adjusting the on-off time proportion of the electromagnetic valve, the probability of uneven air outlet temperature of the air conditioner is reduced, and the user experience is improved.
Fig. 1 is a schematic flow chart of an air conditioner outlet air temperature control method according to an embodiment of the present disclosure. As shown in fig. 1, the process for controlling the outlet air temperature of the air conditioner includes:
step 101: and under the condition that the sampling time corresponding to the preset period is reached, acquiring the current air outlet temperature of each flow path evaporator, and acquiring the current air outlet temperature difference value between the flow path evaporators.
In the embodiment of the disclosure, the indoor evaporator of the air conditioner includes two or more parallel flow paths, each flow path is configured with a corresponding electromagnetic valve, and the flow rate of the refrigerant in the corresponding flow path is controlled by controlling the on and off of the electromagnetic valve.
In the operation process of the air conditioner, the outlet air temperature of each flow path evaporator can be regularly sampled, namely, the outlet air temperature of each flow path evaporator is obtained under the condition that the sampling time corresponding to the preset period is reached, and the current outlet air temperature of each flow path evaporator is obtained at the current sampling time. For example: the inner evaporator of the air conditioner comprises n parallel flow paths, wherein n is a positive integer greater than 1, and the obtained current air outlet temperature of each flow path evaporator can be TP1, TP2, \ 8230;, and TPn respectively.
And obtaining the current air outlet temperature of each flow path evaporator to obtain the current air outlet temperature difference value among the flow path evaporators. For example: n =4, the current outlet air temperature of each flow path evaporator may be TP1, TP2, TP3, TP4, respectively, and the corresponding available current outlet air temperature difference values may be (TP 1-TP 2), (TP 3-TP 1), (TP 1-TP 4), (TP 3-TP 2), (TP 4-TP 2), and (TP 3-TP 4), respectively.
Step 102: and under the condition that one or more current air outlet temperature difference values are larger than a set value, determining the current flow path evaporator to be adjusted and the corresponding current electromagnetic valve thereof according to the current air outlet temperature.
A set value may be determined according to the performance of the air conditioner, for example: 1 ℃, 2 ℃, or 3 ℃, and the like, if one or more current air outlet temperature difference values are larger than a set value, the problem that the air outlet of the indoor evaporator of the air conditioner is uneven is shown. For example: if the air outlet temperature is greater than (TP 3-TP 2) > 3, the problem of uneven air outlet of the indoor evaporator of the air conditioner is indicated, or if the air outlet temperature is greater than (TP 3-TP 2) > 3 and if the air outlet temperature is greater than (TP 3-TP 4) > 3, the problem of uneven air outlet of the indoor evaporator of the air conditioner is also indicated, and at the moment, the refrigerant flow in the evaporator of the corresponding flow path is adjusted by controlling the on-off time proportion of the electromagnetic valve, so that the corresponding air outlet temperature is adjusted.
For the heating operation of the air conditioner, generally, the higher the outlet air temperature is, the larger the refrigerant flow rate in the corresponding flow path evaporator is, therefore, each obtained current outlet air temperature may be sorted, and from the maximum, one, two, or more flow path evaporators corresponding to the current outlet air temperature are selected as the flow path evaporator to be currently adjusted, and therefore, in some embodiments, determining the current flow path evaporator to be currently adjusted according to the current outlet air temperature includes: and determining the first flow path evaporator corresponding to the maximum current air outlet temperature as the current flow path evaporator to be adjusted. Or, in some embodiments, the average outlet air temperature is obtained by summing up each current outlet air temperature, and the second flow path evaporator corresponding to each current outlet air temperature that is greater than the average outlet air temperature is determined as the current flow path evaporator to be adjusted.
Of course, there are many operation modes of the air conditioner, such as heating, cooling or dehumidifying, and so on, and therefore, in some embodiments, determining the current flow path evaporator to be adjusted according to the current outlet air temperature includes: determining the third flow path evaporator corresponding to the minimum current air outlet temperature as the current flow path evaporator to be adjusted; or, after summing up each current outlet air temperature, obtaining an average outlet air temperature, and determining a fourth flow path evaporator corresponding to each current outlet air temperature smaller than the average outlet air temperature as the current flow path evaporator to be adjusted.
As can be seen, there are various ways to determine the current flow path evaporator to be adjusted, and in some embodiments, one or more flow path evaporators with a large refrigerant flow rate may be determined as the current flow path evaporator to be adjusted, for example: and when the air conditioner is in heating operation, determining the first flow path evaporator corresponding to the maximum current air outlet temperature as the current flow path evaporator to be adjusted. Or when the air conditioner operates in a refrigerating mode, determining the third flow path evaporator corresponding to each current air outlet temperature which is lower than the average air outlet temperature as the current flow path evaporator to be adjusted. In some embodiments, one or more flow path evaporators with a smaller refrigerant flow rate may be determined as the flow path evaporator to be currently adjusted, for example: and when the air conditioner is in heating operation, determining the third flow path evaporator corresponding to the minimum current air outlet temperature as the current flow path evaporator to be adjusted. Or when the air conditioner operates in a refrigerating mode, the first flow path evaporator corresponding to the maximum current air outlet temperature is determined as the current flow path evaporator to be adjusted. It is not specifically mentioned.
After the current flow path evaporator to be adjusted is determined, the electromagnetic valve corresponding to the current flow path evaporator to be adjusted is the current electromagnetic valve.
Step 103: and adjusting the on-off time proportion of the current electromagnetic valve in the preset period to reduce the air outlet temperature difference between the flow path evaporators.
And in a preset period, the electromagnetic valve is in a closed state in a first time, and the electromagnetic valve is in an open state in a second time, wherein the sum of the first time and the second time is equal to the preset period. The first time for each solenoid valve may be the same or different, for example: when the air conditioner just starts, probably every very first time all is zero, and every solenoid valve all is in the open mode promptly, along with the operation of air conditioner, the very first time that some solenoid valves correspond probably has changed, like this, through the very first time and the second time that adjust the solenoid valve and correspond, can adjust the refrigerant flow in the flow path evaporimeter of solenoid valve place, and then the air-out temperature that the adjustment corresponds.
When the air conditioner is in heating operation, if a current flow path evaporator to be adjusted with a large refrigerant flow is determined, for example: the first flow path evaporator corresponding to the maximum current air outlet temperature can increase the first time that the current electromagnetic valve is in the closed state in the preset period, and reduce the second time that the current electromagnetic valve is in the open state in the preset period, namely, in the preset period T, the time that the electromagnetic valve is in the closed state is increased, and the time that the electromagnetic valve is in the open state is reduced.
In some embodiments, in the case of two or more second flow path evaporators, adjusting the on-off time ratio of the current solenoid valve in the preset period comprises: determining an adjusting weight value corresponding to each second flow path evaporator according to a ratio value between the current air outlet temperature and the average air outlet temperature corresponding to each second flow path evaporator; and adjusting the on-off time proportion of the current electromagnetic valve in the preset period according to the adjusting weight value and the set adjusting value.
For example: n =6, if the flow path evaporator 1, the flow path evaporator 5, and the flow path evaporator 6 are current flow path evaporators to be adjusted, and the average outlet air temperature TP is obtained by summing up the current outlet air temperatures, then the corresponding adjustment weight values are TP1/TP, TP5/TP, and TP6/TP, respectively. Thus, the preset period is 10s, and the adjustment value is set to 1s, then the first time of the solenoid valve of the flow path evaporator 1 may be increased by 1 × tp1/TP, the first time of the solenoid valve of the flow path evaporator 5 may be increased by 1 × tp5/TP, and the first time of the solenoid valve of the flow path evaporator 6 may be increased by 1 × tp6/TP.
Certainly, adjusting the on-off time ratio of the current electromagnetic valve in the preset period may not only adjust the electromagnetic valve corresponding to the flow path evaporator with a large flow rate, but also adjust the electromagnetic valve corresponding to the flow path evaporator with a small flow rate, and in some embodiments, when the third flow path evaporator corresponding to the minimum current air-out temperature is the current flow path evaporator to be adjusted, adjusting the on-off time ratio of the current electromagnetic valve in the preset period includes: reducing the first time that the current electromagnetic valve is in a closed state in a preset period, and increasing the second time that the current electromagnetic valve is in an open state in the preset period; wherein the sum of the first time and the second time is equal to the preset period.
In the embodiment of the disclosure, whether the air conditioner is in a cooling, heating or dehumidifying mode, or whether the flow path evaporator with a large flow rate is determined as the current flow path evaporator to be adjusted, or whether the flow path evaporator with a small flow rate is determined as the current flow path evaporator to be adjusted, the switching time of the current electromagnetic valve corresponding to the current flow path evaporator to be adjusted in the preset period can be adjusted, so that the outlet air temperature difference between the flow path evaporators is reduced.
Certainly, after the on-off time proportion of the current electromagnetic valve in the preset period is adjusted, the current electromagnetic valve can be controlled to be in a closed state in the first time after the on-off time proportion is adjusted in the preset period, and the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located is cut off; and in a second time after the switching time proportion is adjusted in the preset period, controlling the current electromagnetic valve to be in an open state, and recovering the refrigerant flow in the current flow path evaporator where the current electromagnetic valve is located, so that the refrigerant flow in the corresponding flow path evaporator is adjusted by adjusting the switching time proportion of the corresponding electromagnetic valve in the preset period, and the air outlet temperature difference between the flow path evaporators is reduced.
It can be seen that, in this embodiment, each parallel flow path of the evaporator in the air conditioner room is configured with a corresponding electromagnetic valve for controlling the refrigerant flow, so that when one or more current outlet temperature difference values among the current outlet temperature difference values of the evaporators of the flow paths are greater than a set value, the refrigerant flow in the evaporator of the corresponding flow path can be adjusted by adjusting the on-off time ratio of the corresponding electromagnetic valve in a preset period, so that the outlet temperature difference values among the evaporators of the flow paths are reduced, the probability of uneven outlet temperature of the air conditioner is reduced, and the user experience is improved.
And if no current outlet air temperature difference value is larger than a set value, the on-off time of the electromagnetic valves is not required to be adjusted, namely in some embodiments, under the condition that one or more current outlet air temperature difference values are not larger than the set value, the on-off time proportion of each electromagnetic valve in the preset period is controlled to be unchanged and the electromagnetic valves are operated. Namely, the first time and the second time corresponding to each solenoid valve are kept unchanged in the current preset period.
The following description will integrate the operation flows into a specific embodiment to illustrate the air conditioner outlet air temperature control process provided in the embodiment of the present invention.
In this embodiment, the air-conditioning indoor evaporator includes 8 parallel flow paths, each flow path is provided with a corresponding electromagnetic valve for controlling the refrigerant flow, the preset period is 10s, and the set value is 3 ℃.
Fig. 2 is a schematic flow diagram of an air conditioner outlet air temperature control method according to an embodiment of the present disclosure. With reference to fig. 2, a process for controlling the outlet air temperature of the air conditioner includes:
step 201: is the sampling time reached for 10 s? If yes, go to step 202, otherwise, go back to step 201.
Step 202: and obtaining the current air outlet temperature of each flow path evaporator, and obtaining the current air outlet temperature difference value between the flow path evaporators.
Step 203: is there one or more current outlet air temperature differences greater than 3 ℃? If so, go to step 204, otherwise, go to step 207.
Step 204: and determining the first flow path evaporator corresponding to the maximum current air outlet temperature as the current flow path evaporator to be adjusted, and determining the corresponding current electromagnetic valve.
Step 205: the first time that the current solenoid valve is in the closed state is increased for 10 s.
Thus, the adjustment value is set to be 2s, if the first time that the current electromagnetic valve is in the closed state within 10s before the adjustment is 3s, the first time that the current electromagnetic valve is in the closed state within 10s after the adjustment is 5s, and since the sum of the first time and the second time is 10s, the second time that the current electromagnetic valve is in the open state within 10s after the adjustment is 5s. Of course, if the adjusted first time is greater than or equal to 10s, 10s is determined as the adjusted first time. Or, setting the adjustment value as a proportional value, for example, 10%, and increasing the first time by 10% for each adjustment, that is, if the first time when the current electromagnetic valve is in the closed state within 10s before the adjustment is 3s, the first time when the current electromagnetic valve is in the closed state within 10s after the adjustment is 3+ (1 +10%) s, and the second time when the current electromagnetic valve is in the open state within 10s after the adjustment is 10-3 +10%) s. The specific adjustment process has various ways, which are not listed specifically.
Step 206: and controlling the current operation of the electromagnetic valve according to the adjusted switching time. The control is finished.
Controlling the current electromagnetic valve to be in a closed state within the first time after the switching time proportion is adjusted in 10s, and cutting off the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located; and in the second time after the switching time proportion is adjusted in 10s, controlling the current electromagnetic valve to be in an open state, and recovering the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located. Therefore, the flow rate of the refrigerant of the current flow path evaporator is reduced, and the corresponding outlet air temperature is also reduced, so that the outlet air temperature difference between the evaporator and each flow path evaporator is also reduced.
Step 207: and controlling the on-off time proportion of each electromagnetic valve in a preset period to be unchanged and running. This control is finished.
Controlling the current electromagnetic valve to be in a closed state in the current first time in 10s, and cutting off the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located; and in the current second time of 10s, controlling the current electromagnetic valve to be in an open state, and recovering the flow of the refrigerant in the current flow path evaporator where the current electromagnetic valve is located.
And each current outlet air temperature difference is less than or equal to 3 ℃, which indicates that the outlet air temperature of the evaporator is relatively balanced, the flow of the refrigerant does not need to be adjusted, and the current switching time of the electromagnetic valve is maintained.
Therefore, in this embodiment, the indoor evaporator of the air conditioner includes a plurality of parallel flow paths, and each flow path is configured with a corresponding electromagnetic valve for controlling the refrigerant flow, so that the refrigerant flow in the evaporator of the corresponding flow path can be adjusted by adjusting the on-off time proportion of the electromagnetic valve, the probability of uneven air outlet temperature of the air conditioner is reduced, and the user experience is improved.
In this embodiment, the air conditioner indoor evaporator includes 7 parallel flow paths, each flow path is configured with a corresponding electromagnetic valve for controlling refrigerant flow, the preset period is 12s, and the set value is 2 ℃.
Fig. 3 is a schematic flow diagram of an air conditioner outlet air temperature control method according to an embodiment of the present disclosure. With reference to fig. 3, a process for controlling the outlet air temperature of the air conditioner includes:
step 301: is the sampling time for 12s reached? If yes, go to step 302, otherwise, go back to step 301.
Step 302: and acquiring the current air outlet temperature of each flow path evaporator, and acquiring the current air outlet temperature difference between the flow path evaporators.
Step 303: is there one or more current outlet air temperature differences greater than 2 ℃? If so, go to step 304, otherwise, go to step 308.
Step 304: and adding and summing each current air-out temperature to obtain an average air-out temperature, determining a second flow path evaporator corresponding to each current air-out temperature which is greater than the average air-out temperature as a current flow path evaporator to be adjusted, and determining a corresponding current electromagnetic valve.
The indoor evaporator of the air conditioner comprises 7 flow paths which are connected in parallel, so that two or more second flow path evaporators with the temperature higher than the average outlet air temperature are arranged.
Step 305: and determining an adjusting weight value corresponding to each second flow path evaporator according to the proportion value between the current air outlet temperature and the average air outlet temperature corresponding to each second flow path evaporator.
The ratio value TPi/TP between the current air outlet temperature TPi and the average air outlet temperature TP corresponding to the second flow path evaporator is a corresponding adjusting weight value, and i is greater than 0 and less than or equal to 7.
Step 306: and according to the adjustment weight value and the set adjustment value, obtaining an increment value corresponding to each current electromagnetic valve, and increasing the first time of the corresponding current electromagnetic valve in a closed state within 12s according to the increment value.
Thus, the adjustment value is set to be 2s, and if the first time that the current electromagnetic valve is in the closed state in the 12s before the adjustment is 3s, the first time that the current electromagnetic valve is in the closed state in the 12s after the adjustment is (3 +2 tpi/TP) s. Since the sum of the first time and the second time is 12s, the second time when the current solenoid valve is in the open state in the adjusted 12s is also 12- (3 +2 tpi/TP) s. Of course, if the adjusted first time is greater than or equal to 12s, then 12s is determined as the adjusted first time. Or, setting the adjustment value to be a proportional value, for example, 10%, so that if the first time when the current electromagnetic valve is in the closed state in 12s before the adjustment is 3s, the first time when the current electromagnetic valve is in the closed state in 12s after the adjustment is 3+ (1 +10% + TPi/TP) s. Likewise, there are various ways to specifically adjust the process, which are not specifically enumerated.
Step 307: and controlling the current operation of the electromagnetic valve according to the adjusted switching time. The control is finished.
Step 308: and controlling the on-off time proportion of each electromagnetic valve in a preset period to be unchanged and running. The control is finished.
Therefore, in this embodiment, the indoor evaporator of the air conditioner includes a plurality of parallel flow paths, and each flow path is configured with a corresponding electromagnetic valve for controlling the refrigerant flow, so that the refrigerant flow in the evaporator of the corresponding flow path can be adjusted by adjusting the on-off time proportion of the electromagnetic valve, the probability of uneven air outlet temperature of the air conditioner is reduced, and the user experience is improved.
According to the process for controlling the air-conditioner air-out temperature, a device for controlling the air-conditioner air-out temperature can be constructed.

In some embodiments, further comprising: the first control module is configured to control the current electromagnetic valve to be in a closed state and cut off the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located within a first time after the switching time proportion is adjusted in a preset period; and controlling the current electromagnetic valve to be in an open state within a second time after the switching time proportion is adjusted in the preset period, and recovering the flow of the refrigerant in the current flow path evaporator where the current electromagnetic valve is located.
In some embodiments, further comprising: and the second control module is configured to control the on-off time proportion of each electromagnetic valve in the preset period to be unchanged and operate under the condition that one or more current outlet air temperature difference values are not larger than the set value.
The following specifically describes an air conditioner outlet air temperature control process of the device for air conditioner outlet air temperature control applied to an air conditioner.
In this embodiment, the indoor evaporator of the air conditioner includes 5 parallel flow paths, each flow path is configured with a corresponding electromagnetic valve for controlling the flow rate of the refrigerant, the preset period is 10s, and the set value is 3 ℃.
Fig. 5 is a schematic structural diagram of an air conditioner outlet air temperature control device according to an embodiment of the present disclosure. As shown in fig. 5, the air conditioner outlet air temperature control device includes: an acquisition module 410, a determination module 420, an adjustment module 430, a first control module 440, and a second control module 450.
When the sampling time corresponding to 10s is reached, the obtaining module 410 may obtain the current outlet air temperature of each flow path evaporator, and obtain the current outlet air temperature difference between each flow path evaporator. In this way, when there are one or more current outlet air temperature differences greater than 3 ℃, the determining module 420 may determine the first flow path evaporator corresponding to the maximum current outlet air temperature as the current flow path evaporator to be adjusted, and determine the corresponding current electromagnetic valve. Thus, the adjustment module 430 may increase the first time that the current solenoid is in the closed state for 10s and also decrease the second time that the current solenoid is in the open state for 10 s.
The first control module 440 may control the operation of the current solenoid valve according to the adjusted on-off time. In the first time after the on-off time ratio is adjusted in 10s, the first control module 440 may control the current solenoid valve to be in the closed state, and cut off the flow of refrigerant in the current flow path evaporator where the current solenoid valve is located; and in the second time after the switching time proportion is adjusted in 10s, the first control module 440 can control the current electromagnetic valve to be in an open state, and the flow of the refrigerant in the current flow path evaporator where the current electromagnetic valve is located is recovered. Therefore, the flow rate of the refrigerant of the current flow path evaporator is reduced, and the corresponding outlet air temperature is also reduced, so that the outlet air temperature difference between the evaporator and each flow path evaporator is also reduced.
Of course, if there is no one or more current outlet air temperature differences greater than 3 ℃, the second control module 450 may control the on-off time ratio of each solenoid valve in the preset period to be unchanged and operate. In the first time of 10s, the second control module 450 may control the current electromagnetic valve to be in a closed state, and cut off the flow of refrigerant in the current flow path evaporator where the current electromagnetic valve is located; in the current second time of 10s, the second control module 450 may control the current solenoid valve to be in an open state, and resume the flow of refrigerant in the current flow path evaporator where the current solenoid valve is located.
Therefore, in this embodiment, the indoor evaporator of the air conditioner includes a plurality of parallel flow paths, and each flow path is configured with a corresponding electromagnetic valve for controlling the refrigerant flow, so that the device for controlling the air-conditioning outlet air temperature adjusts the refrigerant flow in the evaporator of the corresponding flow path by adjusting the on-off time proportion of the electromagnetic valve, thereby reducing the probability of uneven air-conditioning outlet air temperature and improving the user experience.
