Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The air conditioning unit control method can be applied to a heat recovery type multi-split air conditioning unit, and the air conditioning unit comprises a controller, a temperature detection element and a plurality of indoor units. The temperature detection element is used for detecting the outlet pipe temperature of the indoor unit. The controller is in communication connection with the temperature detection element to acquire the outlet pipe temperature of the indoor unit detected by the temperature detection element. The controller is in communication connection with each indoor unit to control the operation of each indoor unit. When the air conditioning unit works, part of indoor units are allowed to operate in a heating mode, and meanwhile, part of indoor units operate in a cooling mode.
In one embodiment, as shown in fig. 1, a method for controlling an air conditioning unit is provided, which is described by taking the method as an example of being applied to a controller of the air conditioning unit, and includes the following steps S102 to S108.
And S102, monitoring the working state of each indoor unit in the air conditioning unit.
The operating state includes an operating state and a non-operating state, the operating state may include, but is not limited to, a heating state and a cooling state, and the non-operating state may include, but is not limited to, a shutdown state and a shutdown state.
And S104, when a first indoor unit in a heating state exists in the air conditioning unit and the first indoor unit is in heating operation for a first time period, acquiring the outlet pipe temperature corresponding to the first indoor unit.
The first indoor unit is an indoor unit in a heating state, and the first time length is used for indicating that whether the first indoor unit can meet the heating requirement or not is judged after the first indoor unit is operated for heating for the time length. The specific value of the first duration may be set according to practical situations, and is not limited herein.
A temperature detection element (such as a thermal bulb) may be disposed at each indoor unit, the indoor unit outlet pipe temperature is detected by the thermal bulb, and the controller is connected to each thermal bulb to obtain the indoor unit outlet pipe temperature detected by each thermal bulb.
In one embodiment, a plurality of first indoor units may be in simultaneous heating operation in the air conditioning unit, and in this case, the outlet pipe temperature of each first indoor unit is obtained, and the minimum outlet pipe temperature among the outlet pipe temperatures of all the first indoor units is taken as the outlet pipe temperature corresponding to the first indoor unit.
And S106, when the outlet pipe temperature is lower than the preset temperature and a second indoor unit in an unoperated state exists in the air conditioning unit, determining a target indoor unit according to the second indoor unit.
The preset temperature can be understood as the lowest temperature that the outlet pipe temperature needs to reach when the first indoor unit is in heating operation for the first time period when it is determined that the first indoor unit can meet the heating requirement. That is, if the outlet pipe temperature of the first indoor unit during the first time of the heating operation is lower than the preset temperature, the heating effect of the first indoor unit is considered to be poor, and the heating requirement cannot be met. The specific value of the preset temperature can be set according to the actual situation, and is not limited herein.
The second indoor unit is an indoor unit in a non-operating state, which is understood to be an indoor unit that can be switched to a cooling operation. The target indoor unit is the indoor unit which is finally determined to be in refrigerating operation in the second indoor unit.
And S108, controlling the target indoor unit to perform cooling operation.
For the air conditioning unit, the heating capacity is equal to the energy consumption of the press and the refrigerating capacity, the target indoor unit which is originally in the non-operation state is controlled to be switched into the refrigerating operation, the refrigerating capacity is increased, the heating capacity is increased synchronously, and therefore the heating effect of the first indoor unit is improved.
In the control method of the air conditioning unit, the working state of each indoor unit in the air conditioning unit is monitored; when a first indoor unit in a heating state exists in the air conditioning unit and the first indoor unit is in heating operation for a first time length, acquiring the outlet pipe temperature corresponding to the first indoor unit; when the outlet pipe temperature is lower than the preset temperature and a second indoor unit in an unoperated state exists in the air conditioning unit, determining a target indoor unit according to the second indoor unit; and controlling the cooling operation of the target indoor unit. Therefore, during the heating operation of the air conditioning unit, the indoor unit in the non-operation state is controlled to be switched into the cooling operation, and for the air conditioning unit, the cooling capacity is increased, and the heating capacity is increased synchronously, so that the outlet air temperature of the indoor unit in the heating state is increased, the heating effect is improved, and the comfort of users is improved.
In one embodiment, the second indoor unit in the inactive state comprises at least one of the following: the third indoor unit is in a shutdown state; and the fourth indoor unit is in a shutdown state, and the shutdown time length is greater than or equal to a preset value.
It is understood that the second indoor unit may include only the third indoor unit, only the fourth indoor unit, and both the third indoor unit and the fourth indoor unit.
The third indoor unit is an indoor unit in a shutdown state, and the fourth indoor unit is an indoor unit in a shutdown state, wherein the shutdown time is more than or equal to a preset value. The preset value can be understood as the minimum time required for the shutdown time of the fourth indoor unit to be switched to the cooling operation. The preset value may be set according to actual conditions, and is not limited herein. The fourth indoor unit does not include an indoor unit that has been stopped due to a failure.
If the shutdown duration of the fourth indoor unit is less than the preset value, the fourth indoor unit is considered to be shut down to the temperature point, and the fourth indoor unit is forbidden to be in refrigerating operation. The shutdown to the temperature point means that the fourth indoor unit is suspended when the indoor environment temperature reaches, exceeds or is lower than the set temperature in the running process of the fourth indoor unit, and the shutdown time in the situation is relatively short. For example, the fourth indoor unit originally performs heating operation, the set temperature is 29 ℃, and when the indoor ambient temperature is 32 ℃, the fourth indoor unit stops operating and enters the shutdown state. In another example, the fourth indoor unit originally performs cooling operation, the set temperature is 25 ℃, and when the indoor ambient temperature is 23 ℃, the fourth indoor unit stops operating and enters a shutdown state.
In an embodiment, the step of determining the target indoor unit according to the second indoor unit may specifically include: and if only one second indoor unit is arranged, determining the second indoor unit as the target indoor unit.
When there is only one second indoor unit, the second indoor unit may be a third indoor unit in a shutdown state or a fourth indoor unit in a shutdown state and the shutdown duration is greater than or equal to a preset value, and in both cases, the only second indoor unit is taken as the target indoor unit.
In an embodiment, the step of determining the target indoor unit according to the second indoor unit may specifically include: and if at least two second indoor units exist, determining the indoor unit with the highest priority in the second indoor units as the target indoor unit.
In an embodiment, the step of determining the indoor unit with the highest priority in the second indoor units as the target indoor unit may specifically include any one of the following: if the second indoor unit only comprises a third indoor unit, determining the indoor unit with the highest priority in the third indoor units as a target indoor unit; if the second indoor unit only comprises a fourth indoor unit, determining the indoor unit with the highest priority of the fourth indoor unit as a target indoor unit; and if the second indoor unit simultaneously comprises a third indoor unit and a fourth indoor unit, determining the indoor unit with the highest priority in the third indoor unit as the target indoor unit.
When there are at least two second indoor units, it may only include the third indoor unit, it may only include the fourth indoor unit, and it may also include both the third indoor unit and the fourth indoor unit. The priority of the third indoor unit is higher than that of the fourth indoor unit, namely when the second indoor unit simultaneously comprises the third indoor unit and the fourth indoor unit, the third indoor unit is preferentially selected to be switched into the cooling operation.
And when the target indoor unit is determined from the plurality of third indoor units, the priority of each third indoor unit is obtained, and the third indoor unit with the highest priority is selected as the target indoor unit. Similarly, when the target indoor unit is determined from the plurality of fourth indoor units, the priority of each fourth indoor unit is obtained, and the fourth indoor unit with the highest priority is selected as the target indoor unit.
Specifically, all indoor units in the air conditioning unit may be numbered in advance to set a rank, for example, 1 rank, 2 ranks, and … …, and the higher the rank is, the higher the demand for heating in the room in which the indoor unit is operating is, and the lower the priority is. For example, if the level of the bedroom indoor unit is set to 10 and the level of the bathroom indoor unit is set to 1, the priority of the bedroom indoor unit is lower than that of the bathroom indoor unit, and the bathroom indoor unit is preferentially selected to be in cooling operation when cooling operation needs to be performed and the bedroom indoor unit and the bathroom indoor unit are both in a power-off state.
In one embodiment, as shown in fig. 2, the step of controlling the cooling operation of the target indoor unit may specifically include the following steps S202 to S206.
And S202, taking the target indoor unit as the current target indoor unit, and controlling the cooling operation of the current target indoor unit.
And S204, after the current target indoor unit operates for the second time length in a refrigerating mode, when the outlet pipe temperature is less than the preset temperature in the continuous time length and a second indoor unit which is not in an operating state exists in the air conditioning unit, determining the next target indoor unit according to the second indoor unit.
The second time length is used for indicating whether the first indoor unit can meet the heating requirement under the condition that the target indoor unit is switched to the cooling operation after the target indoor unit is cooled and operated for the time length. After one target indoor unit is switched to the cooling operation, the first indoor unit may still not meet the heating requirement, and under the condition, the next target indoor unit is continuously determined, and the next target indoor unit is switched to the cooling operation, so that the heating effect of the first indoor unit is further improved.
Specifically, after the current target indoor unit operates for the second time length in a refrigerating mode, whether the outlet pipe temperature corresponding to the first indoor unit is smaller than the preset temperature in the continuous time length is judged, if yes, the heating requirement is not met, then, whether a second indoor unit which is not in an operating state exists in the air conditioning unit is further judged, and if yes, the next target indoor unit is determined. If the outlet pipe temperature corresponding to the first indoor unit is greater than or equal to the preset temperature within the continuous time, the heating requirement can be met, the next target indoor unit does not need to be determined, and the unit keeps running in the current running state. The specific values of the second duration and the continuous duration may be set according to actual conditions, and are not limited herein.
It should be noted that, when a next target indoor unit is determined according to a second indoor unit, reference may be made to the description of the step of determining the target indoor unit according to the second indoor unit in the foregoing embodiment, and details are not repeated here.
And S206, taking the next target indoor unit as the current target indoor unit, and returning to the step of controlling the cooling operation of the current target indoor unit.
Specifically, the next target indoor unit is used as a new current target indoor unit, the cooling operation of the new current target indoor unit is controlled, at the moment, two target indoor units are switched to the cooling operation, whether the first indoor unit can meet the heating requirement or not is continuously judged, if not, the new next target indoor unit is continuously determined, and the new next target indoor unit is switched to the cooling operation, so that the heating effect of the first indoor unit is further improved.

And S302, after the target indoor unit operates for the third time length in a refrigerating mode, acquiring the ambient temperature and the set temperature corresponding to the first indoor unit.
And the third time period is used for indicating that the wind speed of the target indoor unit starts to be adjusted after the target indoor unit is cooled and operated for the time period. The specific value of the third time period may be set according to practical situations, and is not limited herein. The ambient temperature is an ambient temperature in a room on which the first indoor unit operates, that is, an ambient temperature in a room in which heating is required. The set temperature can be understood as a heating temperature required by a user.
In one embodiment, there may be a plurality of first indoor units in the air conditioning unit that perform heating operation simultaneously, in this case, the set temperature of each first indoor unit is obtained, and the maximum set temperature among the set temperatures of all the first indoor units is taken as the set temperature corresponding to the first indoor unit.
And S304, controlling the wind speed of the target indoor unit according to the difference value between the set temperature and the ambient temperature.
It can be understood that the set temperature is higher than the ambient temperature in the normal heating condition, and when the difference between the set temperature and the ambient temperature is larger, it indicates that the requirement for the heating capacity is larger, and when the difference between the set temperature and the ambient temperature is smaller, it indicates that the requirement for the heating capacity is smaller.
The larger the air volume of the target indoor unit is, the more beneficial the heating capacity of the first indoor unit is to be improved, so that the air speed of the target indoor unit can be controlled according to the heating capacity requirement, when the heating capacity requirement is large, the air speed of the target indoor unit is improved, when the heating capacity requirement is small, the air speed of the target indoor unit is reduced.
In an embodiment, the step of controlling the wind speed of the target indoor unit according to the difference between the set temperature and the ambient temperature may specifically include any one of the following items: when the difference value is smaller than a first preset difference value, controlling the target indoor unit to operate at a low wind level; when the difference is greater than or equal to a first preset difference and less than or equal to a second preset difference, controlling the target indoor unit to run at a medium gear; and when the difference value is larger than a second preset difference value, controlling the target indoor unit to operate at a high windshield.
And when the difference value between the set temperature and the environment temperature is smaller than a first preset difference value, considering that the heating capacity requirement of the user on the first indoor unit is smaller, and controlling the target indoor unit to run at a low wind gear after the target indoor unit is cooled. And when the difference value between the set temperature and the ambient temperature is greater than or equal to a first preset difference value and less than or equal to a second preset difference value, considering that the heating capacity requirement of the user on the first indoor unit is large, and controlling the target indoor unit to run at a medium wind gear after the target indoor unit is cooled. And when the difference value between the set temperature and the ambient temperature is greater than a second preset difference value, considering that the heating capacity of the first indoor unit is greatly required by a user, and controlling the target indoor unit to run at a high wind gear after the target indoor unit is cooled. The first preset difference is smaller than the second preset difference, and the first preset difference and the second preset difference may be set according to an actual situation, which is not limited herein.
