[0099] In the present embodiment, the control method of the environment conditioning system comprises steps S10-S30:

[0100] Step S10, control the environment conditioning system to run in a cooling mode, and acquire a condensation state parameter of the indoor unit.

[0103] Step S20, in a case where the condensation state parameter meets a condensation condition, obtaining an air outlet cooperation state of the at least two air outlets;

In this embodiment, the condensation state parameter includes a dew point temperature of the indoor unit and an indoor heat exchanger temperature of the indoor unit, and the condensation condition includes that a temperature difference value of the dew point temperature and the indoor heat exchanger temperature is greater than or equal to a preset temperature difference, or the temperature difference value of the dew point temperature and the indoor heat exchanger temperature is greater than or equal to the preset temperature difference and lasts for a second preset time length.

[0107] The condensation prevention operation can be one of the following: adjusting the air outlet cooperation state of the at least two air outlets (for example, increasing the number of opened air outlets, increasing the air outlet amount of the opened air outlets, switching the currently opened air outlet to an air outlet with smaller air resistance, and the like), reducing the compressor operation frequency, increasing the indoor fan operation speed, turning on the indoor dehumidification device, and the like.

[0108] The air outlet cooperation state is different, the cold amount aggregation in the indoor unit is different, and the corresponding condensation prevention operation is different. For example, in a case where the air outlet cooperation state is a first state, a first operation is determined as the condensation prevention operation; in a case where the air outlet cooperation state is a second state, reducing the compressor operation frequency is the condensation prevention operation; wherein the cold amount aggregation degree corresponding to the first state is greater than the cold amount aggregation degree corresponding to the second state, and the first operation is set to increase the air outlet amount of the at least two air outlets.

[0109] The embodiment provides a control method of an environmental regulation system. In the environmental regulation system provided with the at least two air outlets, when the indoor unit has a condensation risk in the refrigeration process, the selection of the condensation prevention operation is performed based on the air outlet cooperation state of the at least two air outlets, so that when the at least two air outlets of the indoor unit cooperate to outlet air in different states, the condensation risk can be effectively reduced, and the system operation reliability is improved.

[0110] In an embodiment, the at least two air outlets include a first air outlet and a second air outlet, the first air outlet has a larger area than the second air outlet and / or the air outlet direction of the indoor air fan in the indoor unit is towards the first air outlet and not towards the second air outlet, and the indoor heat exchanger is arranged in the indoor air duct of the indoor unit. In this embodiment, the first air outlet is the side air outlet described above, and the second air outlet is the lower air outlet described above. In this embodiment, the step of controlling the environmental regulation system to perform the anti-condensation operation according to the air outlet matching state includes:

[0111] In the case where the second air outlet is open in the air outlet matching state, the indoor unit is controlled to close the second air outlet and open the first air outlet;

[0112] In the case where the second air outlet is not open in the air outlet matching state, the environmental regulation system is controlled to operate to increase the temperature of the indoor heat exchanger;

[0113] The anti-condensation operation includes closing the second air outlet and opening the first air outlet of the indoor unit, or increasing the temperature of the indoor heat exchanger.

[0114] In the air outlet matching state, the first air outlet can be open or closed while the second air outlet is open. When the first air outlet is in an open state while the second air outlet is closed, the first air outlet can be maintained open, and the air outlet area can be maintained unchanged or increased when the first air outlet is maintained open. When the first air outlet is in a closed state while the second air outlet is closed, the first air outlet can be switched from closed to open. In the air outlet matching state, the first air outlet is open alone while the second air outlet is closed.

[0115] When the first air outlet is open, the air outlet area can be a fixed area, or an area determined according to the actual operation of the indoor unit.

[0116] In this embodiment, the indoor unit includes the air outlet assembly described above, the air outlet assembly includes a first switch door and a second switch door, the first air outlet includes a first air outlet area and a second air outlet area, the first switch door is arranged to adjust the air outlet amount of the first air outlet area, and the second switch door is arranged to adjust the air outlet amount of the second air outlet area and the second air outlet. The second switch door closes the second air outlet and opens the second air outlet area (the second switch door can be in the fourth position described above), and the first switch door can open or shield the first air outlet area.

[0117] When the first air guide area is in the open state (the first switch door is in the third position or a position between the first position and the third position) when the second air outlet is closed, the first switch door can be maintained in the current position (for example, maintained in the third position) or adjusted to a position with a larger air outlet area of the first air outlet area (for example, adjusted from a position between the first position and the third position to the third position); when the first air guide area is in the closed state (the first switch door is in the first position) when the second air outlet is closed, the first switch door can be adjusted to the third position or another target position.

[0118] In the process of controlling the indoor unit to close the second air outlet and open the first air outlet, other components of the environment adjusting system maintain the current running parameters, for example, at least one of the following can be included: the compressor maintains the current frequency, the indoor fan maintains the current speed, and the outdoor fan maintains the current speed.

[0119] The way to improve the temperature of the indoor heat exchanger can include at least one of the following: increasing the speed of the indoor fan, reducing the frequency of the compressor, increasing the target temperature of the indoor heat exchanger, increasing the opening degree of the throttling device, etc.

[0120] In the embodiment, the air outlet resistance of the second air outlet in the indoor unit is larger than that of the first air outlet, and when the second air outlet is opened, cold energy is easy to accumulate near the second air outlet, which leads to the risk of condensation. At this time, the opened air outlet is switched to the first air outlet with smaller air resistance, and the second air outlet with large air resistance is no longer used for air outlet, so that the cold energy is more easily blown out of the outdoor unit, avoiding the accumulation of cold energy, and at the same time, the system refrigeration capacity is not weakened, realizing the effective reduction of the condensation risk while ensuring the refrigeration effect; When the second air outlet is closed, it can be considered that the current condensation risk of the indoor unit is not caused by the accumulation of cold energy due to the too large air outlet resistance, at this time, the temperature of the indoor heat exchanger is increased, and the temperature difference between the dew point temperature and the temperature of the indoor heat exchanger is reduced, thereby effectively reducing the condensation risk of the indoor unit and ensuring the effective improvement of the system operation reliability.

[0121] In other embodiments, in the air outlet cooperation state, when the second air outlet is opened, the anti-condensation operation can be determined according to the air outlet state of the first air outlet in the air outlet cooperation device (such as the position of the first switch door and the position of the second switch door). Different air outlet states correspond to different anti-condensation operations, for example, when the first air outlet is opened, the environment adjusting system is controlled to run to improve the temperature of the indoor heat exchanger; when the first air outlet is closed, the indoor unit is controlled to close the second air outlet and open the first air outlet.

[0122] In other embodiments, in the case that the second air outlet is opened in the air outlet cooperation state, the indoor unit can also be controlled to maintain opening of the second air outlet and opening of the first air outlet.

[0123] In a possible implementation, after the step of controlling the indoor unit to close the second air outlet and open the first air outlet in the case that the second air outlet is opened in the air outlet cooperation state, the method further includes:

[0124] The environmental regulation system is controlled to run to increase the temperature of the indoor heat exchanger in the case that the indoor unit meets the condensation condition after the first preset time period.

[0125] When the duration of the closed second air outlet and the opened first air outlet reaches the first preset time period, the condensation state parameter of the current indoor unit can be acquired again, and it is determined whether the condensation state parameter meets the condensation condition.

[0126] In the case that the indoor unit does not meet the condensation condition after the first preset time period, the environmental regulation system can be controlled to maintain the current state.

[0127] In this embodiment, when the indoor unit has a condensation risk, the air outlet cooperation state of the at least two air outlets of the indoor unit is regulated, and the temperature of the indoor heat exchanger is further increased only when the condensation risk still exists after the regulation, which is conducive to reducing the condensation risk of the indoor unit while ensuring the refrigeration effect of the system.

[0128] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above description, and will not be described hereinafter. On this basis, please refer to Figure 5 The step of controlling the environmental regulation system to run to increase the temperature of the indoor heat exchanger includes:

[0129] In step S31, the dew point temperature of the space where the indoor unit is located is acquired.

[0130] The dew point temperature can be detected by a dew point sensor, or can be calculated according to the detected temperature and humidity.

[0131] In step S32, a reference evaporation temperature is determined according to the dew point temperature.

[0132] In the case that the environmental regulation system includes one indoor unit, in one implementation, the dew point temperature can be used as the reference evaporation temperature. In another implementation, the reference evaporation temperature can be determined according to the actual running condition of the indoor unit in a temperature range greater than or equal to the dew point temperature.

[0133] In the case that the environment conditioning system comprises at least two indoor units, different indoor units are arranged to be distributed in different indoor spaces, and the reference evaporation temperature can be determined according to at least two dew point temperatures corresponding to the at least two indoor units. In this embodiment, the reference evaporation temperature is determined according to the maximum temperature in all dew point temperatures corresponding to all first indoor units, wherein the first indoor unit is the indoor unit whose corresponding condensation state parameter satisfies the condensation condition. The first indoor unit is the indoor unit with the energy demand.

[0134] Step S33, increasing the reference evaporation temperature to obtain a target evaporation temperature;

[0135] The reference evaporation temperature is increased according to a temperature adjustment parameter (such as a temperature adjustment coefficient or a temperature adjustment amplitude) to obtain the target evaporation temperature. For example, the sum of the temperature adjustment amplitude and the reference evaporation temperature is taken as the target evaporation temperature.

[0136] The temperature adjustment parameter can be a pre-set fixed parameter, or a parameter determined according to the actual operation of the environment conditioning system. For example, the temperature adjustment parameter can be determined according to the air outlet matching state of the current first air outlet and second air outlet, and different air outlet matching states correspond to different temperature adjustment parameters. When the environment conditioning system comprises more than one indoor unit, the temperature adjustment parameter can be determined according to the relationship value between the first quantity and the second quantity in all indoor units with energy demand, wherein the first quantity is the number of indoor units with the second air outlet opened, and the second quantity is the number of indoor units without the second air outlet opened.

[0137] The target evaporation temperature is the target temperature that the indoor heat exchanger in the indoor unit needs to reach in the evaporation state.

[0138] Step S34, controlling the operation of the environment conditioning system according to the target evaporation temperature.

[0139] The target evaporation temperature is used to control the adjustment opening of the throttling device, and / or the target evaporation temperature is used to control the operation frequency of the compressor, and / or the target evaporation temperature is used to control the operation speed of the indoor fan, so that the indoor heat exchanger in the indoor unit can reach the target evaporation temperature.

[0140] In the case that the environment conditioning system comprises one indoor unit, the coil temperature of the indoor heat exchanger in the indoor unit can be obtained as the actual evaporation temperature.

[0141] In the case that the environment conditioning system comprises at least two indoor units, different indoor units are arranged to be distributed in different indoor spaces, and the current coil temperature of the indoor heat exchanger in each indoor unit can be taken as the current evaporation temperature, and the actual evaporation temperature can be determined according to at least two current evaporation temperatures.

[0142] The operation of the environmental conditioning system is controlled according to the relationship between the actual evaporation temperature and the target evaporation temperature.

[0143] In this embodiment, the temperature difference between the actual evaporating temperature of the environmental conditioning system and the target evaporating temperature is determined; if the temperature difference is less than a first preset temperature difference, the compressor frequency is controlled to decrease; if the temperature difference is greater than a second preset temperature difference, the compressor frequency is controlled to increase; wherein the first preset temperature difference is less than or equal to the second preset temperature difference. The frequency adjustment amplitude when the compressor frequency is decreased or increased can be a preset fixed amplitude or a parameter determined based on the actual operating conditions of the indoor unit. In this embodiment, the frequency adjustment amplitude when the compressor frequency is decreased is negatively correlated with the temperature difference; and / or the frequency adjustment amplitude when the compressor frequency is increased is positively correlated with the temperature difference. When the temperature difference is less than the first preset temperature difference, a first frequency adjustment amplitude can be determined based on the temperature difference range within which the temperature difference falls, and the compressor frequency can be controlled to decrease based on the first frequency adjustment amplitude. When the temperature difference is greater than the second preset temperature difference, a second frequency adjustment amplitude can be determined based on the temperature difference range within which the temperature difference falls, and the compressor frequency can be controlled to increase based on the second frequency adjustment amplitude.

[0144] In this embodiment, the above-mentioned method is helpful to reduce the condensation risk of indoor units in different indoor spaces, thereby effectively improving the reliability of system operation.

[0145] In other embodiments, in the process of determining the reference evaporating temperature based on all dew point temperatures corresponding to all first indoor units, the reference evaporating temperature can also be determined based on the average value of the dew point temperatures corresponding to all first indoor units, or the first temperature compensation value can be determined based on the air outlet coordination status of at least two air outlets corresponding to each first indoor unit, different air outlet coordination statuses correspond to different weight values, and the reference evaporating temperature is obtained by taking a weighted average of all dew point temperatures according to the weight values.

[0146] In one feasible embodiment, current evaporation temperatures of indoor heat exchangers in all second indoor units are obtained, where the second indoor units are the indoor units currently having energy demand; and an actual evaporation temperature of the environmental conditioning system is determined based on the rated capacity and the current evaporation temperature corresponding to each second indoor unit.

[0147] The indoor unit with energy demand refers to an indoor unit that is in cooling mode and whose corresponding indoor temperature is greater than or equal to the set temperature of the corresponding indoor unit.

[0148] A corresponding weighted value is determined according to the rated capacity corresponding to the second indoor unit. Since the weighted value is positively correlated with the corresponding rated capacity, the actual evaporation temperature can be obtained by performing a weighted average calculation on the evaporation temperatures corresponding to all second indoor units according to the weighted value.

[0149] In the embodiment, by the above-mentioned manner, it is beneficial to realize that each indoor unit can reach the target evaporation temperature under the system operation regulation, effectively reduce the condensation risk of each indoor unit, and improve the system reliability.

[0150] In other embodiments, the number ratio of the cooperation state of the at least two air outlets in the second indoor unit in all cooperation states of all second indoor units can be combined to determine a corresponding weighted value, and the weighted average of the evaporation temperatures of all second indoor units is calculated according to the weighted value to obtain the actual evaporation temperature.

[0151] Based on any of the above embodiments, in the third embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be described in detail. On this basis, referring to Figure 6 , the step of controlling the operation of the environment regulation system in the refrigeration mode further includes:

[0152] Step S101, obtaining the running speed of the indoor fan in the indoor unit;

[0153] Step S102, in the case that the running speed is less than or equal to the preset speed, executing the step of obtaining the condensation state parameter of the indoor unit.

[0154] The preset speed can be a fixed parameter set in advance, or a temperature determined according to the dew point temperature of the space where the indoor unit is located.

[0155] In the case that the running speed is greater than the preset speed, the environment regulation system is controlled to maintain the current state, and the condensation risk is not determined and the condensation operation is not executed.

[0156] In the embodiment, the risk of cold accumulation in the indoor unit is high when the indoor fan runs at a low speed, so the condensation risk is identified when the indoor fan runs at a low speed, which is beneficial to improve the accuracy of the condensation risk identification, thereby further improving the system operation reliability and ensuring the refrigeration effect.
