A third aspect of the invention provides a computer-readable storage medium.
The invention provides a control method of an air conditioning system, the air conditioning system at least comprises a first multi-split air conditioning system, the first multi-split air conditioning system comprises a first system outdoor unit and a plurality of first system indoor units, and the control method comprises the following steps: acquiring first installation position parameters of a first system outdoor unit and a plurality of first system indoor units; and controlling at least one first system indoor unit to work according to the plurality of first installation position parameters.
The invention provides a control method applied to an air conditioning system, wherein the air conditioning system at least comprises a first multi-split air conditioning system, the first multi-split air conditioning system comprises a first system outdoor unit and a plurality of first system indoor units, and the plurality of first system indoor units are matched with the first system outdoor unit for use. Particularly, the relative positions of the plurality of first system indoor units and the first system outdoor unit are different, so that the first multi-split air conditioning system has different operation energy efficiency when the first system outdoor unit is used in cooperation with different first system indoor units.
Therefore, the control method provided by the invention firstly obtains the first installation position parameters of the first system outdoor unit and the plurality of first system indoor units, obtains the relative position of each first system indoor unit and the first system outdoor unit, compares the plurality of first installation position parameters, and then controls at least one first system indoor unit to work according to the plurality of first installation position parameters, so as to improve the operation energy efficiency of the air conditioning system and further reduce the operation cost on the premise of ensuring the same refrigeration or heating effect.
It should be noted that the control method provided by the present invention can control one or more indoor units of the first system to operate according to actual needs. That is, when only one indoor unit needs to be started, one first system indoor unit can be controlled to work; when a plurality of indoor units are required to be started, a plurality of first system indoor units can be controlled to work.
According to the control method of the air conditioning system, the first system indoor units are controlled to work according to the first installation position parameters of the plurality of first system outdoor units and the plurality of first system indoor units, and the operation energy efficiency of the air conditioning system can be effectively improved on the premise of the same refrigeration or heating effect, so that the operation cost is reduced.
According to the control method of the air conditioning system in the above technical solution of the present invention, the following additional technical features may be further included:
in the above technical solution, the first installation position parameter includes: a first transverse distance between the first system indoor unit and the first system outdoor unit; the method comprises the following steps of controlling at least one first system indoor unit to work according to a plurality of installation position parameters, and specifically comprises the following steps: and controlling the indoor units of the first system with the set number to be sequentially started according to the sequence of the first transverse distances from small to large.
In this technical solution, the first installation position parameter includes: the first system indoor unit is at a first transverse distance from the first system outdoor unit. In particular, in the multi-split air conditioning system, the refrigerant pipes are mostly arranged in the transverse direction, and the transverse distance between the plurality of first-system indoor units and the first-system outdoor unit determines the length of the refrigerant from the first-system outdoor unit to the first-system indoor units. The shorter the transverse distance between the indoor unit of the first system and the outdoor unit of the first system is, the higher the operation energy efficiency of the air conditioning system is, and the lower the operation cost of the air conditioning system is.
Therefore, when the first system indoor units are controlled to work, the plurality of first system indoor units are sequenced from small to large according to the first transverse distance, and then the set number of first system indoor units are controlled to be sequentially started according to the sequence according to the number of the first system indoor units to be started, so that the operation energy efficiency of the air conditioning system is improved to the maximum extent, and the operation cost of the air conditioning system is reduced.
Specifically, the set number is the number of indoor units that need to be turned on, that is, the number of rooms that a user needs to live in.
In any of the above technical solutions, the first installation position parameter includes: a first installation height difference between the first system indoor unit and the first system outdoor unit; the method comprises the following steps of controlling at least one first system indoor unit to work according to a plurality of installation position parameters, and specifically comprises the following steps: and controlling the indoor units of the first system with the set number to be sequentially started according to the sequence of the first installation height difference from small to large.
In this technical solution, the first installation position parameter includes: and the first installation height difference between the indoor unit of the first system and the outdoor unit of the first system. In the operation process of the first multi-split air-conditioning system, due to the first height difference and the different densities of the gaseous refrigerant and the liquid refrigerant, certain gravitational potential energy exists between the first system outdoor unit and the plurality of first system indoor units, and the smaller the gravitational potential energy, the easier the operation of the refrigerant between the first system outdoor unit and the first system indoor units is, the higher the operation energy efficiency of the air-conditioning system is, and the lower the operation cost of the air-conditioning system is.
Therefore, according to the control method of the air conditioning system, when the first system indoor units are controlled to work, the plurality of first system indoor units are sequenced from small to large according to the first installation height difference corresponding to the first system outdoor units, and then the first system indoor units with the set number are controlled to be sequentially started according to the sequence according to the number of the first system indoor units needing to be started, so that the higher the operation energy efficiency of the air conditioning system is improved to the greatest extent, and the operation cost of the air conditioning system is reduced.
Specifically, the set number is the number of indoor units that need to be turned on, that is, the number of rooms that a user needs to live in.
In any of the above technical solutions, the first installation position parameter includes: the first transverse distance between the first system indoor unit and the first system outdoor unit, and the first installation height difference between the first system indoor unit and the first system outdoor unit; the method comprises the following steps of controlling at least one first system indoor unit to work according to a plurality of installation position parameters, and specifically comprises the following steps: controlling a set number of first system indoor units to be sequentially started according to the sequence of the first transverse distances from small to large, and sequentially starting according to the sequence of the first installation height differences from small to large under the condition that the first transverse distances are equal; or controlling the set number of the first system indoor units to be sequentially started according to the sequence of the first installation height differences from small to large, and sequentially starting according to the sequence of the first transverse distances from small to large under the condition that the first installation height differences are equal.
In this technical solution, the first installation position parameter includes: the first system indoor unit and the first system outdoor unit are arranged at a first transverse distance, and the first system indoor unit and the first system outdoor unit are arranged at a first installation height difference. In particular, the first lateral distance and the first height difference both directly affect the operation efficiency of the first air conditioning system, and the smaller the first lateral distance, the higher the operation efficiency of the first air conditioning system is, and the smaller the first height difference, the higher the operation efficiency of the first air conditioning system is.
Therefore, according to the control scheme of the air conditioning system provided by the invention, the two factors are comprehensively considered when the indoor units of the first system are controlled to work, and the set number of the indoor units of the first system are controlled to be installed and arranged to be sequentially started according to the number of the indoor units of the first system to be started, so that the operation energy efficiency of the air conditioning system is improved to the greatest extent, and the operation cost of the air conditioning system is reduced. Particularly, when only one first system indoor unit needs to be controlled to work, one first system indoor unit with the smallest first transverse distance can be directly controlled.
Specifically, the set number is the number of indoor units that need to be turned on, that is, the number of rooms that a user needs to live in.
Specifically, when the first system indoor units are controlled to work, the plurality of first system indoor units can be sorted in the order from the first transverse distance from small to large, and then the first system indoor units with the same first transverse distance can be sorted in the order from the first height difference from small to large; and then controlling the first system indoor units with the set number to be started in sequence according to the number of the first system indoor units to be started.
Specifically, when the first system indoor units are controlled to work, the plurality of first system indoor units can be firstly sequenced according to the sequence that the first height difference is from small to large, and then the first system indoor units with the same first height difference are sequenced according to the sequence that the first transverse distance is from small to large; and then, controlling the first system indoor units with set number to be installed and arranged in the sequence according to the number of the first system indoor units to be started.
In any of the above technical solutions, the air conditioning system further includes a second multi-split air conditioning system, and before the step of obtaining the first installation location parameters of the outdoor unit of the first system and the plurality of indoor units of the first system, the method further includes: acquiring the refrigerant demand of all the indoor units of the first system in an opening state in the first multi-split air-conditioning system; acquiring the refrigerating capacity of an outdoor unit of a first system; and controlling at least one second multi-split air conditioning system to work according to the refrigerant demand and the refrigerating capacity.
In the technical scheme, for the multi-split air conditioning system, when the operation load percentage of the indoor unit of the multi-split air conditioning system is within a certain interval, the operation efficiency is highest and the energy is saved most. Therefore, according to the control method of the air conditioning system, before the first installation position parameters of the first system outdoor unit and the plurality of first system indoor units are obtained, the refrigerant demand of all the first system indoor units in the first multi-split air conditioning system in an open state is obtained, the refrigerating capacity of the first system outdoor unit is obtained at the same time, the current operation condition of the first multi-split air conditioning system can be determined according to the refrigerant demand and the refrigerant refrigerating capacity, the current operation load percentage of the indoor units of the first multi-split air conditioning system can be obtained, and the first multi-split air conditioning system is controlled to operate according to actual conditions.
In any of the above technical solutions, the step of controlling the second multi-split air conditioning system to operate according to the refrigerant demand and the cooling capacity specifically includes: calculating the ratio of the refrigerant demand to the refrigerating capacity; controlling the second multi-split air conditioning system to be started on the basis of the condition that the ratio is greater than or equal to the set threshold; and controlling the second multi-split air conditioning system to be closed under the condition that the ratio is smaller than the set threshold, and executing the step of controlling at least one first system indoor unit to work according to the plurality of first installation position parameters.
In the technical scheme, after the refrigerant demand of all the indoor units of the first system in an open state in the first multi-split air-conditioning system and the refrigerating capacity of the outdoor unit of the first system are obtained, the ratio of the refrigerant demand to the refrigerating capacity is calculated to obtain the operating load percentage of the indoor units of the first multi-split air-conditioning system; and then, judging whether the ratio of the refrigerant demand to the refrigerating capacity is greater than or equal to a set threshold value or not, and controlling the first multi-split air-conditioning system and the second multi-split air-conditioning system to work according to a comparison result.
Specifically, when the ratio of the refrigerant demand to the cooling capacity is greater than or equal to a set threshold value, it is indicated that the first multi-split air-conditioning system is already at a high operation efficiency, and the number of the indoor units operating the first multi-split air-conditioning system is increased to reduce the operation efficiency of the first multi-split air-conditioning system, and at this time, the operation of the second multi-split air-conditioning system is controlled according to the number of the indoor units to be started.
Specifically, when the ratio of the refrigerant demand to the refrigerating capacity is smaller than a set threshold, it is stated that increasing the number of operating first system indoor units does not reduce the operating efficiency of a multi-split air conditioning system, and at this time, controlling the second multi-split air conditioning system to continue to keep a closed state, and controlling the set number of first system indoor units to be opened according to the number of indoor units to be opened.
In any of the above technical solutions, the second multi-split air conditioning system includes a second system outdoor unit and a plurality of second system indoor units, and the step of controlling the second multi-split air conditioning system to be turned on based on the ratio being greater than the set threshold specifically includes: acquiring second installation position parameters of the outdoor unit of the second system and the plurality of indoor units of the second system; and controlling at least one second system indoor unit to work according to the plurality of second installation position parameters.
In the technical scheme, the second multi-split air conditioning system comprises a second system outdoor unit and a plurality of second system indoor units. The relative positions of the second system indoor units and the second system outdoor units are different, so that the second multi-split air-conditioning system has different working efficiency when the second system outdoor units are matched with different second system indoor units for use. Therefore, in the process of controlling the opening of the second multi-split air-conditioning system, the second installation position parameters of the second system outdoor unit and the plurality of second system indoor units are firstly obtained, the relative position of each second system indoor unit and the second system outdoor unit is obtained, then the plurality of second installation position parameters are compared, and at least one second system indoor unit is controlled to work according to the plurality of second installation position parameters, so that the operation energy efficiency of the air-conditioning system is improved on the premise of ensuring the same refrigeration or heating effect, and the operation cost is further reduced.
It should be noted that the control method provided by the present invention can control one or more second system indoor units to work according to actual needs. That is, when only one indoor unit needs to be started, one second system indoor unit can be controlled to work; when a plurality of indoor units need to be started, a plurality of second system indoor units can be controlled to work.
In any of the above technical solutions, the second installation position parameter includes: a second transverse distance between the second system indoor unit and the second system outdoor unit; controlling at least one second system indoor unit to work according to the plurality of second installation position parameters, and specifically comprising the following steps: and controlling the set number of the second system indoor units to be sequentially started according to the sequence of the second transverse distances from small to large.

In particular, in the multi-split air conditioning system, the refrigerant pipes are mostly arranged in the transverse direction, and the transverse distance between the plurality of second-system indoor units and the second-system outdoor unit determines the length of the refrigerant from the second-system outdoor unit to the second-system indoor units. The shorter the transverse distance between the indoor unit of the second system and the outdoor unit of the second system is, the higher the operation energy efficiency of the air conditioning system is, and the lower the operation cost of the air conditioning system is.
Therefore, when the second system indoor units are controlled to work, the plurality of second system indoor units are sequenced from small to large according to the second transverse distance, and then the set number of second system indoor units are controlled to be sequentially started according to the sequencing according to the number of the second system indoor units to be started, so that the operation energy efficiency of the air-conditioning system is improved to the maximum extent, and the operation cost of the air-conditioning system is reduced.

The first multi-split air conditioning system comprises a first system outdoor unit and a plurality of first system indoor units, wherein the plurality of first system indoor units are matched with the first system outdoor unit; the second multi-split air conditioning system comprises a second system outdoor unit and a plurality of second system indoor units, and the plurality of second system indoor units are matched with the second system outdoor unit for use.
A control method of an air conditioning system proposed in this embodiment is shown in fig. 2, and the control method of the air conditioning system includes:
fig. 2 is a flowchart illustrating a control method of an air conditioning system according to an embodiment, and as shown in fig. 2, the control method of the air conditioning system includes:
step 202, acquiring the refrigerant demand of all the indoor units of the first system in an opening state in the first multi-split air-conditioning system;
step 204, obtaining the refrigerating capacity of the outdoor unit of the first system;
step 206, calculating the ratio of the refrigerant demand to the refrigerating capacity;
step 208, judging whether the ratio is greater than or equal to a set threshold, if so, executing step 210, otherwise, executing step 212 and step 214;
step 210, controlling a second multi-split air conditioning system to be started;
step 212, controlling the second multi-split air conditioning system to be closed;
and 214, controlling at least one first system indoor unit to work according to the plurality of first installation position parameters.
For the multi-split air conditioning system, when the operation load percentage of the indoor unit is in a certain interval, the operation efficiency is highest and the energy is saved most. Therefore, in the control method of the air conditioning system provided in this embodiment, before the first installation position parameters of the first system outdoor unit and the plurality of first system indoor units are obtained, the refrigerant demand of all the first system indoor units in the first multi-split air conditioning system in an open state is obtained, the refrigerating capacity of the first system outdoor unit is obtained at the same time, and according to the refrigerant demand and the refrigerant refrigerating capacity, the current operation state of the first multi-split air conditioning system can be determined, that is, the current operation load percentage of the indoor units of the first multi-split air conditioning system can be obtained, so that the first multi-split air conditioning system is controlled to operate according to an actual situation.
It should be noted that the control method provided by the present invention can control one or more indoor units of the first system to operate according to actual needs. That is, when only one indoor unit needs to be started, one first system indoor unit can be controlled to work; when a plurality of indoor units are required to be started, a plurality of first system indoor units can be controlled to work.
Specifically, after the refrigerant demand of all the indoor units of the first system in an open state in the first multi-split air-conditioning system and the refrigerating capacity of the outdoor unit of the first system are known, the ratio of the refrigerant demand to the refrigerating capacity is calculated to obtain the operating load percentage of the indoor units of the first multi-split air-conditioning system; and then, judging whether the ratio of the refrigerant demand to the refrigerating capacity is greater than or equal to a set threshold value or not, and controlling the first multi-split air-conditioning system and the second multi-split air-conditioning system to work according to a comparison result.
In a specific embodiment, when the ratio of the refrigerant demand to the cooling capacity is greater than or equal to a set threshold, it is indicated that the first multi-split air-conditioning system is already at a high operation efficiency, and the number of the indoor units operating the first multi-split air-conditioning system is increased to reduce the operation efficiency of the first multi-split air-conditioning system, and at this time, the operation of the second multi-split air-conditioning system is controlled according to the number of the indoor units to be started.
In a specific embodiment, when the ratio of the refrigerant demand to the cooling capacity is smaller than a set threshold, it is indicated that increasing the number of the first system indoor units does not reduce the operating efficiency of a multi-split air conditioning system, and at this time, the second multi-split air conditioning system is controlled to continue to be in a closed state, and the set number of the first system indoor units is controlled to be opened according to the number of the indoor units to be opened.
In this embodiment, the plurality of second system indoor units and the plurality of second system outdoor units are arranged at different relative positions, which may cause the second multi-split air conditioning system to have different work efficiencies when the second system outdoor units are used in cooperation with different second system indoor units. Therefore, in the process of controlling the opening of the second multi-split air-conditioning system, the second installation position parameters of the second system outdoor unit and the plurality of second system indoor units are firstly obtained, the relative position of each second system indoor unit and the second system outdoor unit is obtained, then the plurality of second installation position parameters are compared, and the second system indoor units are controlled to work according to the plurality of second installation position parameters, so that the operation energy efficiency of the air-conditioning system is improved on the premise of ensuring the same refrigeration or heating effect, and the operation cost is further reduced.
In a specific embodiment, the second installation location parameter includes: and the second transverse distance between the indoor unit of the second system and the outdoor unit of the second system. In particular, in the multi-split air conditioning system, the refrigerant pipes are mostly arranged in the transverse direction, and the transverse distance between the plurality of second-system indoor units and the second-system outdoor unit determines the length of the refrigerant from the second-system outdoor unit to the second-system indoor units. The shorter the transverse distance between the indoor unit of the second system and the outdoor unit of the second system is, the higher the operation energy efficiency of the air conditioning system is, and the lower the operation cost of the air conditioning system is.
Therefore, when the second system indoor units are controlled to work, the plurality of second system indoor units are sequenced from small to large according to the second transverse distance, and then the set number of second system indoor units are controlled to be sequentially started according to the sequencing according to the number of the second system indoor units to be started, so that the operation energy efficiency of the air-conditioning system is improved to the maximum extent, and the operation cost of the air-conditioning system is reduced.
In a specific embodiment, the second installation location parameter includes: and the second installation height difference of the second system indoor unit and the second system outdoor unit. In the operation process of the second multi-split air-conditioning system, due to the second height difference and the different densities of the gaseous refrigerant and the liquid refrigerant, certain gravitational potential energy exists between the second system outdoor unit and the plurality of second system indoor units, and the smaller the gravitational potential energy, the easier the operation of the refrigerant between the second system outdoor unit and the second system indoor units is, the higher the operation energy efficiency of the air-conditioning system is, and the lower the operation cost of the air-conditioning system is.
Therefore, when the second system indoor units are controlled to work, the plurality of second system indoor units are sequenced according to the sequence that the second installation height difference corresponding to the second system outdoor units is from small to large, then the set number of second system indoor units are controlled to be started according to the number of the second system indoor units needing to be started, and the higher the operation energy efficiency of the air-conditioning system is improved to the greatest extent, so that the operation cost of the air-conditioning system is reduced.
In a specific embodiment, the second installation location parameter includes: and the second transverse distance between the indoor units of the second system and the outdoor units of the second system and the second installation height difference between the indoor units of the second system and the outdoor units of the second system are obtained. In particular, the second lateral distance and the second height difference both directly affect the operation efficiency of the second air conditioning system, and the smaller the second lateral distance, the higher the operation efficiency of the second air conditioning system is, and the smaller the second height difference, the higher the operation efficiency of the second air conditioning system is.
Therefore, according to the control scheme of the air conditioning system provided by the invention, the two factors are comprehensively considered when the indoor units of the second system are controlled to work, and the set number of the indoor units of the second system are controlled to be installed and arranged to be sequentially started according to the number of the indoor units of the second system to be started, so that the operation energy efficiency of the air conditioning system is improved to the greatest extent, and the operation cost of the air conditioning system is reduced.
Specifically, when the second system indoor units are controlled to work, the plurality of second system indoor units can be sorted according to the sequence of the second transverse distances from small to large, and then the second system indoor units with the same second transverse distances can be sorted according to the sequence of the second height differences from small to large; and then controlling the second system indoor units with the set number to be started in sequence according to the number of the second system indoor units to be started.
Specifically, when the second system indoor units are controlled to work, the plurality of second system indoor units can be firstly sequenced according to the sequence that the second height difference is from small to large, and then the second system indoor units with the same second height difference are sequenced according to the sequence that the second transverse distance is from small to large; and then controlling the second system indoor units with the set number to be started in sequence according to the number of the second system indoor units to be started.
Specifically, the set number is the number of indoor units that need to be turned on, that is, the number of rooms that a user needs to live in.
In this embodiment, the preset value range is set to be 50% to 75%.
In this embodiment, when the ratio of the refrigerant demand to the cooling capacity is greater than or equal to a and less than or equal to b, the operation energy efficiency of the first multi-split air conditioning system is high. Wherein, the value range of a is 10 to 30 percent, and the value range of b is 10 to 30 percent.
That is, when the operation load percentage of the indoor unit of the first multi-split air-conditioning system is less than or equal to a, the indoor unit of the first system of the first air-conditioning system is continuously controlled to be started under the condition of need; when the operation load percentage of the indoor unit of the first multi-split air-conditioning system is larger than a and smaller than b, the indoor unit of the first system of the first air-conditioning system is continuously controlled to be started under the condition of need; and when the operation load percentage of the indoor unit of the first multi-split air-conditioning system is more than b, controlling the second system indoor unit of the second air-conditioning system to be started under the condition of need.
