Description

Technical Field

[0001] The present invention relates to the technical field of multi-connected air-conditioning control, and in particular to a method and system for prioritizing control of a rear-opening mode based on a household central air-conditioning. Background Art

[0002] A multi-split system is a central air conditioning system with multiple indoor units connected to an outdoor unit. Multi-split indoor unit air conditioners are installed in different rooms or areas. When setting the operating mode of the indoor unit air conditioner, the user may set it to different modes (cooling, dehumidification, heating, and air supply). Since there is only one outdoor unit, there will be a problem of user-set mode conflicts. The existing technology has cooling mode priority, heating mode priority, and first-on priority, but in home air conditioning applications, there is still a problem that the set target mode cannot be obtained without satisfying the user's set mode. Summary of the invention

[0003] In view of the above-mentioned defects, the purpose of the present invention is to propose a post-opening mode priority control method and system based on household central air conditioning, so as to solve the problems of the existing multi-split air conditioners, such as the inability to respond to user adjustments in time and the cumbersome user adjustment operations.

[0004] To achieve this purpose, the present invention adopts the following technical solution: a method for prioritizing the rear opening mode of a household central air conditioner, comprising the following steps:

[0005] Setting a detection cycle, and at the end of the detection cycle, obtaining the state change parameters of each air conditioner indoor unit within the detection cycle;

[0006] The operation module of the air conditioner outdoor unit is adjusted according to the state change parameter.

[0007] Preferably, the state change parameters include a change in the operating mode of the indoor unit and a changed number of indoor units.

[0008] Preferably, adjusting the operation module of the air conditioner outdoor unit according to the state change parameter is specifically as follows:

[0009] Step S1: Determine whether the number of indoor units is 1. If the number of indoor units is 1, take the indoor unit as the reference indoor unit and execute step S2; if the number of indoor units is not 1, take all indoor units with changed operation modules as the reference indoor units and execute step S2;

[0010] Step S2: Determine whether the operating mode change of the reference indoor unit is the shutdown mode. If it is the shutdown mode, adjust the operating mode of the outdoor unit of the air conditioner based on the operating mode of the other unchanged indoor units. If it is not the shutdown mode, obtain the priority of the operating mode in the reference indoor unit, take the operating mode with the highest priority as the reference mode, and adjust the operating mode of the outdoor unit of the air conditioner based on the preset relationship between the reference mode and the operating mode of the outdoor unit of the air conditioner.

[0011] Preferably, the specific steps of adjusting the outdoor unit of the air conditioner based on the operating mode of the other unchanged indoor unit and the operating mode of the outdoor unit are as follows:

[0012] When at least one of the indoor units in the unchanged indoor unit operation modes is in the on mode, the current operation mode of the outdoor unit of the air conditioner is maintained;

[0013] When all indoor units in the other unchanged indoor unit operation modes are in shutdown mode, the operation mode of the air conditioner outdoor unit is changed to the shutdown mode.

[0014] Preferably, the method further includes the following steps: after the operation module of the air conditioner outdoor unit is modified, determining whether there is a conflict between the operation mode of the air conditioner outdoor unit and the operation mode of the air conditioner indoor unit; if so, shutting down the conflicting air conditioner indoor unit.

[0015] Preferably, the priority of the operating modes in the air conditioner is: cooling>heating>dehumidification>air supply.

[0016] A rear-opening mode priority control system based on a household central air conditioner, using the rear-opening mode priority control method based on a household central air conditioner, comprising a cycle setting module and an adjustment module;

[0017] The cycle setting module is used to set the detection cycle, and at the end of the detection cycle, obtain the state change parameters of each air conditioner indoor unit in the cycle;

[0018] The regulating module is used to regulate the operation module of the air conditioner outdoor unit according to the state change parameter.

[0019] Preferably, the adjustment module includes a confirmation submodule and a setting submodule;

[0020] The confirmation submodule is used to determine whether the number of indoor units is 1. If the number of indoor units is 1, the indoor unit is used as a reference indoor unit; if the number of indoor units is not 1, all indoor units with changed operation modules are used as reference indoor units;

[0021] The setting submodule is used to determine whether the operating mode change of the reference indoor unit is a shutdown mode. If it is a shutdown mode, the operating mode of the outdoor unit of the air conditioner is adjusted based on the operating mode of the other unchanged indoor units; if it is a non-shutdown mode, the priority of the operating mode of the reference indoor unit is obtained, and the operating mode with the highest priority is used as the reference mode. Based on the preset relationship between the reference mode and the operating mode of the outdoor unit of the air conditioner, the operating mode of the outdoor unit of the air conditioner is adjusted.

[0022] Preferably, the setting submodule includes a first unit;

[0023] The first unit is used to maintain the current operation mode of the outdoor unit of the air conditioner when at least one of the operation modes of the indoor units that have not changed is in the on mode;

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1-2 As shown, a method for prioritizing the rear opening mode of a household central air conditioner comprises the following steps:

[0034] Setting a detection cycle, and at the end of the detection cycle, obtaining the state change parameters of each air conditioner indoor unit within the detection cycle;

[0035] The operation module of the air conditioner outdoor unit is adjusted according to the state change parameter.

[0036] In the existing multi-split air-conditioning system, cooling mode priority, heating mode priority, first-start priority, etc., when other air-conditioning units are started in a certain operating mode, for example, someone turns on the heating in other places, the air-conditioning unit will enter the heating operating mode. If other air-conditioning units need cooling at this time, they need to turn off the heating air-conditioning units, or change the operating mode of the heating air-conditioning units to cooling. In this way, the air-conditioning can be cooled, and it cannot respond to the user's adjustment instructions in time.

[0037] In order to solve the problem that the air conditioner outdoor unit cannot respond in time due to the mode conflict caused by the operating mode of the air conditioner indoor unit. In the present invention, a detection cycle is set. When the air conditioner indoor unit is started, the state change parameters of the air conditioner indoor unit are obtained based on the detection cycle, wherein the state change parameters include the change of the operating mode of the indoor unit and the number of changed indoor units. After the state change parameters are obtained, the current operating mode change of the air conditioner indoor unit can be judged according to the changed state parameters, and the air conditioner outdoor unit is adjusted according to the current operating mode change of the indoor unit to make it immediately adapt to the operating mode of the indoor unit.

[0038] The present invention adjusts the operating mode of the air-conditioning outdoor unit based on the air-conditioning command input later, reduces the user's operating steps when adjusting the air-conditioning indoor unit, enables the air-conditioning indoor unit to respond to the user's adjustment command in time, reduces the air-conditioning indoor unit shutdown problem, avoids unnecessary loss, and optimizes the energy efficiency ratio.

[0039] In order to be able to respond to the user's adjustment needs in a timely manner, the detection period can be set to 0.5 to 2 seconds.

[0040] Preferably, the state change parameters include a change in the operating mode of the indoor unit and a changed number of indoor units.

[0041] Preferably, adjusting the operation module of the air conditioner outdoor unit according to the state change parameter is specifically as follows:

[0042] Step S1: Determine whether the number of indoor units is 1. If the number of indoor units is 1, take the indoor unit as the reference indoor unit and execute step S2; if the number of indoor units is not 1, take all indoor units with changed operation modules as the reference indoor units and execute step S2;

[0043] Step S2: Determine whether the operating mode change of the reference indoor unit is the shutdown mode. If it is the shutdown mode, adjust the operating mode of the outdoor unit of the air conditioner based on the operating mode of the other unchanged indoor units. If it is not the shutdown mode, obtain the priority of the operating mode in the reference indoor unit, take the operating mode with the highest priority as the reference mode, and adjust the operating mode of the outdoor unit of the air conditioner based on the preset relationship between the reference mode and the operating mode of the outdoor unit of the air conditioner.

[0044] Preferably, the specific steps of adjusting the outdoor unit of the air conditioner based on the operating mode of the other unchanged indoor unit and the operating mode of the outdoor unit are as follows:

[0045] When at least one of the indoor units in the unchanged indoor unit operation modes is in the on mode, the current operation mode of the outdoor unit of the air conditioner is maintained;

[0046] When all indoor units in the other unchanged indoor unit operation modes are in shutdown mode, the operation mode of the air conditioner outdoor unit is changed to the shutdown mode.

[0047] Since more than one user may adjust the air conditioner indoor unit during the detection cycle, if multiple users continue to adjust the air conditioner indoor unit, due to the different adjustment instructions of multiple users, corresponding mode conflicts may occur. Therefore, when making adjustments, it is necessary to first determine whether the number of indoor units is 1. When there is only one reference indoor unit, there is no need to consider the conflict between adjustments. Then determine the change in the operating mode. When the operating mode of the indoor unit changes to the shutdown mode, consider the current remaining unchanged indoor unit operating mode. If there is an air conditioner indoor unit with a startup mode, in order for the air conditioner indoor unit to continue to operate, the air conditioner outdoor unit does not need to be turned off at this time. The air conditioner outdoor unit maintains the current operating mode. If after the reference indoor unit is turned off, all indoor units in the other unchanged indoor unit operating modes are in the shutdown mode, there is no need to turn on the air conditioner outdoor unit. At this time, the operating mode of the air conditioner outdoor unit can be changed to the shutdown mode.

[0048] When the operation mode of the indoor unit changes to a non-shutdown mode, it is necessary to determine the priority of the reference indoor unit, and use the operation mode with the highest priority as the reference mode. For example, when the number of reference indoor units is greater than 1, the current reference indoor unit 1 is adjusted to the cooling operation mode, the reference indoor unit 2 is adjusted to the air supply operation mode, and the reference indoor unit 3 is adjusted to the dehumidification operation mode. The priority of the operation modes in the air conditioner is: cooling>heating>dehumidification>air supply. At this time, the cooling operation mode is used as the reference mode, and then the operation mode of the air conditioner outdoor unit is adjusted based on the preset relationship between the reference mode and the air conditioner outdoor unit operation mode. The preset relationship can be set as follows:

[0049]

[0050] Therefore, according to the preset relationship, when the reference mode is the cooling operation mode, the operation mode of the outdoor unit is switched to the cooling operation mode.

[0051] Preferably, the method further includes the following steps: after the operation module of the air conditioner outdoor unit is modified, determining whether there is a conflict between the operation mode of the air conditioner outdoor unit and the operation mode of the air conditioner indoor unit; if so, shutting down the conflicting air conditioner indoor unit.

[0052] Currently, when the operating mode of the air conditioner outdoor unit is switched, the operating mode of the air conditioner outdoor unit may conflict with the operating mode of the air conditioner indoor unit whose operating mode is changed. For example, after the air conditioner outdoor unit is switched to the cooling operating mode, the air conditioner indoor unit in a certain room is in the heating operating mode. Since the heating operating mode and the cooling operating mode conflict with each other, in order to avoid poor user performance, the air conditioner indoor unit that conflicts with the existing air conditioner outdoor unit operating mode needs to be turned off.

[0053] Preferably, the priority of the operating modes in the air conditioner is: cooling>heating>dehumidification>air supply.

[0055] The cycle setting module is used to set the detection cycle, and at the end of the detection cycle, obtain the state change parameters of each air conditioner indoor unit in the cycle;

[0056] The regulating module is used to regulate the operation module of the air conditioner outdoor unit according to the state change parameter.

[0057] Preferably, the adjustment module includes a confirmation submodule and a setting submodule;

[0058] The confirmation submodule is used to determine whether the number of indoor units is 1. If the number of indoor units is 1, the indoor unit is used as a reference indoor unit; if the number of indoor units is not 1, all indoor units with changed operation modules are used as reference indoor units;

[0059] The setting submodule is used to determine whether the operating mode change of the reference indoor unit is a shutdown mode. If it is a shutdown mode, the operating mode of the outdoor unit of the air conditioner is adjusted based on the operating mode of the other unchanged indoor units; if it is a non-shutdown mode, the priority of the operating mode of the reference indoor unit is obtained, and the operating mode with the highest priority is used as the reference mode. Based on the preset relationship between the reference mode and the operating mode of the outdoor unit of the air conditioner, the operating mode of the outdoor unit of the air conditioner is adjusted.

[0060] Preferably, the setting submodule includes a first unit;

[0061] The first unit is used to maintain the current operation mode of the outdoor unit of the air conditioner when at least one of the operation modes of the indoor units that have not changed is in the on mode;

[0062] When all indoor units in the other unchanged indoor unit operation modes are in shutdown mode, the operation mode of the air conditioner outdoor unit is changed to the shutdown mode.
