It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

Fig. 1 is a method schematic diagram of an embodiment of a control method of a water multi-connected air conditioner provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the method for controlling a water multi-connected air conditioner includes at least steps S110 and S120.
And step S110, detecting the humidity value of the room when the room where the indoor unit is located has a cooling load requirement.
Specifically, whether a room where the indoor unit is located has a cooling load demand is detected, and if no cooling load demand exists, it is indicated that the indoor unit is not started or a heating mode is started, and a standby state or heating operation is kept. And when the room where the indoor unit is located has a cooling load demand, detecting the humidity value of the room where the indoor unit is located.
And step S120, controlling the internal machine to enter a dehumidification mode to operate or operate according to set parameters or correcting the operation parameters of the internal machine according to the detected humidity value.
Specifically, the indoor unit is controlled to enter a dehumidification mode to operate or operate according to set parameters or modify the set parameters of the indoor unit according to the humidity value range of the room in which the humidity value is located.
(1) And if the humidity value is larger than a first preset humidity threshold value, controlling the internal machine to enter a dehumidification mode to operate.
The first preset humidity threshold may specifically be a critical value of a preset high humidity environment and a comfortable environment, and may be obtained through an experimental test. For example, the first preset humidity value is 75%, and when the RH is detected to be greater than 75%, the internal machine is controlled to automatically switch to the dehumidification mode. At the moment, the display or the manual operator of the internal machine displays that the set working condition (namely the set parameter) of the user is not changed.
(2) And if the humidity value is smaller than or equal to a first preset humidity threshold value and larger than a second preset humidity threshold value, controlling the internal machine to operate according to set parameters.
For example, the first preset humidity value is 75%, and when the RH is detected to be greater than 75%, the internal machine is controlled to enter the dehumidification mode.
(3) And if the humidity value is less than or equal to a third preset humidity threshold value, correcting the operation parameters of the internal machine.
The operation parameters specifically comprise an operation rotating speed corresponding to the current set wind gear and a target inner pipe temperature corresponding to the current set temperature. Specifically, the modifying the operation parameter of the internal machine may specifically include: and increasing the running rotating speed corresponding to the current set wind gear by a preset rotating speed value and/or increasing the temperature of the target inner pipe corresponding to the current set temperature by a preset temperature value according to the current set wind gear. Optionally, different windshields correspond to different preset temperature values, for example, a higher windshield corresponds to a lower preset temperature value. The target inner tube temperature is the target temperature of the tube temperature of the indoor heat exchanger. Preferably, in order to avoid generating too much noise, if the set wind gear is the highest wind gear of the affiliated internal machine, the affiliated internal machine is controlled to operate according to the set parameters, that is, the operating speed corresponding to the set wind gear is not increased.
For example, the wind gear of the internal machine is a high wind gear, a medium wind gear and a low wind gear in sequence, wherein the preset temperature value corresponding to the medium wind gear is a ℃, the preset temperature value corresponding to the low wind gear is B ℃, and a is less than B. When a user sets the wind gear to be a high wind gear (highest wind gear), the internal machine of the system runs according to set parameters; when a user sets a wind gear as a medium wind gear, the rotating speed of the fan is increased to a preset rotating speed value on the basis of the operating rotating speed of the medium wind gear, and the temperature of a target inner pipe is increased by A ℃; when the wind gear is set to be the low wind gear by a user, the rotating speed of the fan is increased to a preset rotating speed value to operate on the basis of the operating rotating speed of the low wind gear, and the temperature of the target inner pipe is increased by B ℃.
During the refrigeration operation, a dehumidification phenomenon inevitably occurs, that is, during the refrigeration process, a part of the cooling load of the unit inevitably participates in dehumidification, but when the humidity value is less than or equal to a certain threshold value (namely, the third preset humidity threshold value, RH is less than or equal to 40%), the dehumidification load of the unit is lower under the condition of low humidity, and all the dehumidification load is used for refrigeration and cooling, at the moment, the corresponding control logic target temperature correction can be carried out on the unit, and the target temperature can be increased under the premise of no dehumidification load to achieve the same refrigeration effect, so that the purpose of energy-saving operation is achieved.
The operating rotating speed corresponding to the current set wind gear is increased by a preset rotating speed value, so that the contact between wind and an indoor heat exchanger can be reduced, the dehumidification efficiency is reduced, and excessive dehumidification is avoided. Increasing the target inner tube temperature can reduce the frequency of the compressor, thereby enabling energy savings.
Optionally, if the humidity value is greater than a first preset humidity threshold, after the indoor unit is controlled to enter the dehumidification mode, when it is detected that the humidity value of the room is less than or equal to the first preset humidity threshold, the indoor unit is controlled to exit the dehumidification mode and operate according to set parameters.
For example, the humidity value RH of the room is continuously detected after the indoor unit is controlled to enter the dehumidification mode, and when the humidity value RH is detected to be less than or equal to 75%, the indoor unit is controlled to exit the dehumidification mode and operate according to set parameters, where the set parameters include, for example, a set temperature (i.e., a target temperature) and/or a set wind gear, i.e., operate according to a target temperature and/or a wind gear set by a user.
According to the embodiment of the invention, when the indoor environment is a high-humidity environment, the dehumidification mode is firstly started to carry out rapid dehumidification, and when the indoor humidity value is reduced to be equal to or lower than the first preset humidity threshold value, the normal refrigeration mode is operated, so that the energy consumption on the dehumidification latent heat can be reduced.
In order to clearly illustrate the technical solution of the present invention, an execution flow of the control method of the multi-connected air conditioner according to the present invention is described below with an embodiment.
Fig. 2 is a method schematic diagram of a control method of a water multi-connected air conditioner according to an embodiment of the present invention. As shown in fig. 2, detecting whether a room in which the air conditioner is located has a cooling load demand, and if the room does not have the cooling load demand, continuing standby or heating operation; and if the cooling load requirement exists, detecting the humidity value RH of the room where the indoor unit is located, and controlling the indoor unit according to the detected humidity value RH. When RH is detected to be larger than 75%, the internal machine to which the control device belongs is switched to a dehumidification mode, the set working condition of a user displayed by a manual operator is unchanged, and when RH is detected to be larger than 40% and smaller than or equal to 75%, the set working condition of the current user is kept; when the RH is detected to be less than or equal to 40%, the temperature of a set wind shield and a target inner pipe is detected, if a user sets a high wind shield, the high wind shield is kept, if the user sets a middle wind shield, the rotating speed of the fan is increased to a preset rotating speed value on the basis of the operating rotating speed of the middle wind shield for operation, the set temperature is increased by A ℃, if the user sets a low wind shield, the rotating speed of the fan is increased to a preset rotating speed value on the basis of the operating rotating speed of the low wind shield for operation, and the set temperature is increased by B ℃.
Fig. 3 is a schematic structural diagram of an embodiment of a control device of a water multi-connected air conditioner according to the present invention. As shown in fig. 3, the control apparatus 100 of the water multi-connected air conditioner includes a detection unit 110 and a control unit 120.
The detection unit 110 is configured to detect a humidity value of a room in which the internal machine is located when a cooling load is required in the room.
Specifically, whether a room where the indoor unit is located has a cooling load demand is detected, and if no cooling load demand exists, it is indicated that the indoor unit is not started or a heating mode is started, and a standby state or heating operation is kept. The detection unit 110 detects the humidity value of the room where the indoor unit is located when the indoor unit is located has a cooling load demand.
The control unit 120 is configured to control the corresponding internal machine to enter a dehumidification mode to operate or operate according to a set parameter or correct an operation parameter of the corresponding internal machine according to the humidity value detected by the detection unit.
Specifically, the control unit 120 controls the internal machine to enter the dehumidification mode to operate or operate according to the set parameter or modify the operation parameter of the internal machine according to the humidity value range in which the humidity value of the room is located.
(1) And if the humidity value is larger than a first preset humidity threshold value, controlling the internal machine to enter a dehumidification mode to operate.
The first preset humidity threshold may specifically be a critical value of a preset high humidity environment and a comfortable environment, and may be obtained through an experimental test. For example, the first preset humidity value is 75%, and when the RH is detected to be greater than 75%, the internal machine is controlled to automatically switch to the dehumidification mode. At the moment, the display or the manual operator of the internal machine displays that the set working condition (namely the set parameter) of the user is not changed.
(2) And if the humidity value is smaller than or equal to a first preset humidity threshold value and larger than a second preset humidity threshold value, controlling the internal machine to operate according to set parameters.
For example, the first preset humidity value is 75%, and when the RH is detected to be greater than 75%, the internal machine is controlled to enter the dehumidification mode.
(3) And if the humidity value is less than or equal to a third preset humidity threshold value, correcting the operation parameters of the internal machine.
The operation parameters may specifically include an operation rotation speed corresponding to the current set gear and a target inner pipe temperature corresponding to the current set temperature. Specifically, the modifying the operation parameter of the internal machine may specifically include: and increasing the running rotating speed corresponding to the current set wind gear by a preset rotating speed value and/or increasing the temperature of the target inner pipe corresponding to the current set temperature by a preset temperature value according to the current set wind gear. Optionally, different windshields correspond to different preset temperature values, for example, a higher windshield corresponds to a lower preset temperature value. The target inner tube temperature is the target temperature of the tube temperature of the indoor heat exchanger. Preferably, in order to avoid generating too much noise, if the set wind gear is the highest wind gear of the affiliated internal machine, the affiliated internal machine is controlled to operate according to the set parameters, that is, the operating speed corresponding to the set wind gear is not increased.
For example, the wind gear of the internal machine is a high wind gear, a medium wind gear and a low wind gear in sequence, wherein the preset temperature value corresponding to the medium wind gear is a ℃, the preset temperature value corresponding to the low wind gear is B ℃, and a is less than B. When a user sets the wind gear to be a high wind gear (highest wind gear), the internal machine of the system runs according to set parameters; when a user sets a wind gear as a medium wind gear, the rotating speed of the fan is increased to a preset rotating speed value on the basis of the operating rotating speed of the medium wind gear, and the temperature of a target inner pipe is increased by A ℃; when the wind gear is set to be the low wind gear by a user, the rotating speed of the fan is increased to a preset rotating speed value to operate on the basis of the operating rotating speed of the low wind gear, and the temperature of the target inner pipe is increased by B ℃.
During the refrigeration operation, a dehumidification phenomenon inevitably occurs, that is, during the refrigeration process, a part of the cooling load of the unit inevitably participates in dehumidification, but when the humidity value is less than or equal to a certain threshold value (namely, the third preset humidity threshold value, RH is less than or equal to 40%), the dehumidification load of the unit is lower under the condition of low humidity, and all the dehumidification load is used for refrigeration and cooling, at the moment, the corresponding control logic target temperature correction can be carried out on the unit, and the target temperature can be increased under the premise of no dehumidification load to achieve the same refrigeration effect, so that the purpose of energy-saving operation is achieved.
The operating rotating speed corresponding to the current set wind gear is increased by a preset rotating speed value, so that the contact between wind and an indoor heat exchanger can be reduced, the dehumidification efficiency is reduced, and excessive dehumidification is avoided. Increasing the target inner tube temperature can reduce the frequency of the compressor, thereby enabling energy savings.
Optionally, according to another embodiment of the present invention, the detecting unit 110 is further configured to: after the control unit 120 controls the internal machine to enter a dehumidification mode, detecting whether the humidity value of the room is less than or equal to a first preset humidity threshold value; the control unit 120 is further configured to: when the detecting unit 110 detects that the humidity value of the room is less than or equal to a first preset humidity threshold, the internal unit is controlled to exit the dehumidification mode and operate according to set parameters.
For example, after the control unit 120 controls the belonging indoor unit to enter the dehumidification mode, the detection unit 110 continues to detect the humidity value RH of the room, and when it is detected that RH is less than or equal to 75%, the control unit 120 controls the belonging indoor unit to exit the dehumidification mode and operate according to the setting parameters, which include, for example, the setting temperature (i.e., the target temperature) and/or the setting wind level, i.e., operate according to the user-set working condition.
According to the embodiment of the invention, when the indoor environment is a high-humidity environment, the dehumidification mode is firstly started to carry out rapid dehumidification, and when the indoor humidity value is reduced to be equal to or lower than the first preset humidity threshold value, the normal refrigeration mode is operated, so that the energy consumption on the dehumidification latent heat can be reduced.
