Referring to fig. 2, the air conditioning system 10 includes at least one indoor unit 11, at least one wire controller 13, and an outdoor unit 12. Each of the line controllers 13 is communicatively connected to a corresponding one of the indoor unit devices 11. The wire controller 13 is configured to determine the corrected temperature according to the temperature adjustment mode and the set temperature of the at least one indoor unit 11, and the outdoor temperature and the indoor temperature. The outdoor unit 12 is communicatively connected to at least one wire controller 13, and the outdoor unit 12 is configured to: acquiring a correction temperature; the water is supplied to the indoor unit 11 according to the corrected temperature.

According to the control method and the air conditioning system 10, the indoor working condition is determined through the indoor temperature, the temperature regulation mode of the indoor unit equipment 11 and the set temperature, and the outdoor working condition is determined through the outdoor temperature, so that the outdoor unit equipment 12 determines the temperature of water supply according to the indoor working condition and the outdoor working condition, the temperature of water supply is more suitable for actual requirements, and compared with the mode of water supply according to the fixed water temperature, the energy consumption is reduced.

The corrected temperature is a result obtained by integrating the temperature adjustment mode of the indoor unit 11, the temperature desired by the user, the indoor and outdoor temperature environments, and the like. The corrected temperature may reflect that the water supply has a reasonable temperature according to the current application scenario, and may be as suitable as possible to the user's expectations, and may also consider the energy consumption of the air conditioning system 10.

The temperature adjustment mode may include a cooling mode and a heating mode. When the indoor unit 11 is in the cooling mode, the set temperature corresponding to the indoor unit 11 will be a temperature lower than the indoor temperature, and the outdoor unit 12 will provide water with a lower temperature to the indoor unit 11 to meet the cooling requirement of the indoor unit 11. When the indoor unit 11 is in the heating mode, the set temperature corresponding to the indoor unit 11 will be a temperature higher than the indoor temperature, and the outdoor unit 12 will provide water with a higher temperature to the indoor unit 11 to meet the heating requirement of the indoor unit 11.

The user can select the temperature adjustment mode of the indoor unit 11 through the line controller 13.

The outdoor unit 12 can supply water according to a specific water temperature, so that the problem of energy consumption increase caused by the fact that the outdoor unit 12 supplies water with a single temperature, which is overheated or supercooled, to meet the temperature regulation requirement as much as possible can be avoided, and the condition that the compressor of the outdoor unit 12 is in high-load operation for a long time can be avoided, so that the energy efficiency of the unit can be improved.

In fig. 2, the indoor unit equipment 11 may include an air conditioner indoor unit or a floor heating. The indoor unit 11 and the outdoor unit 12 can achieve a cooling effect or a heating effect using water as a refrigerant.

In fig. 2, the air conditioning system 10 may include a water pump 14. The water pump 14 is provided on a water supply pipe between the indoor unit 11 and the outdoor unit 12. When the indoor unit 11 is turned on, the corresponding wire controller 13 may feed back to the outdoor unit 12 that the indoor unit 11 is turned on, so that the outdoor unit 12 is turned on, and the air conditioning system 10 correspondingly turns on the water pump 14, so that the outdoor unit 12 can supply water to the indoor unit 11.

In fig. 2, a water supply pipe between the indoor unit 11 and the outdoor unit 12 is indicated by a solid line, and a communication channel between the line controller 13 and the outdoor unit 12 is indicated by a broken line. The communication channel may be characterized as either wired or wireless communication.

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the wire controller 13 is configured to: acquiring a temperature adjustment reference value and a temperature adjustment coefficient, wherein the temperature adjustment coefficient comprises a first coefficient, a second coefficient and a third coefficient, the temperature adjustment reference value is determined according to a temperature adjustment mode of the indoor unit equipment 11, the first coefficient is determined according to outdoor temperature, the second coefficient is determined according to indoor temperature, and the third coefficient is determined according to indoor temperature and set temperature; and determining the corrected temperature according to the temperature regulating reference value and the temperature regulating coefficient.

Thus, the effect of reasonably adjusting the water supply temperature of the outdoor unit apparatus 12 can be achieved.

The temperature adjustment reference value is determined according to the temperature adjustment mode of the indoor unit 11, so that the outdoor unit 12 can determine whether to perform heating on the basis of a higher temperature or perform cooling on the basis of a lower temperature.

The first coefficient may reflect the outdoor temperature, the second coefficient may reflect the indoor temperature, and the third coefficient may reflect the indoor temperature change in the process of temperature adjustment of the indoor unit 11 according to the set temperature. The third coefficient may be determined by a difference between the room temperature and the set temperature.

Determining the corrected temperature according to the temperature adjustment reference value and the temperature adjustment coefficient may include:

and calculating the temperature regulating coefficient as a weight of the temperature regulating reference value to determine the corrected temperature.

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the wire controller 13 is configured to: and calculating the temperature regulating coefficient as a weight of the temperature regulating reference value to determine the corrected temperature.

In this manner, a specific scheme for determining the water supply temperature that the outdoor unit apparatus 12 needs to reach can be provided.

In the case where the temperature adjustment mode of the indoor unit 11 is the cooling mode, the corrected temperature can be determined by the following formula:

T＝m*a*b*c；

wherein T is the corrected temperature, m is the temperature adjustment reference value in the cooling mode, a is the first coefficient in the cooling mode, b is the second coefficient in the cooling mode, and c is the third coefficient in the cooling mode.

In the case where the temperature adjustment mode of the indoor unit 11 is the heating mode, the corrected temperature may be determined by the following formula:

T＝n*d*e*f；

wherein T is the corrected temperature, n is the temperature regulating reference value in the heating mode, d is the first coefficient in the heating mode, e is the second coefficient in the heating mode, and f is the third coefficient in the heating mode.

For the tempering reference value, according to different tempering modes, it can be configured to correspondingly different values. Specifically, in the cooling mode, the temperature adjustment reference value may be 7 ℃, or the outdoor unit 12 may perform correction adjustment based on 7 ℃; in the heating mode, the temperature adjustment reference value may be 25 ℃, or the outdoor unit 12 may be corrected and adjusted based on 25 ℃.

In practical terms, in the related art, the default water supply temperature of the household water system during cooling is 7 ℃, and the default water supply temperature during heating is 25 ℃, so that the configuration of default temperature adjustment of the household water system can be matched.

For the same temperature adjustment mode, the temperature adjustment reference value can be selected within a corresponding numerical range.

In addition, it can be understood that, for those skilled in the art, according to different practical situations, other calculation methods (such as adding and subtracting the correction amount of the temperature, substituting the corresponding coefficient into other designed mathematical function models to calculate the result) may be adopted to obtain the corrected temperature, so that it is convenient to quickly obtain the result according to the practical situations and adjust the target water supply temperature of the outdoor unit 12.

				a	1	1.2	1.4

TABLE 1

As can be determined from table 1, when the indoor unit 11 is in the cooling mode, the corresponding first coefficient is different according to the section in which the outdoor temperature is located. As the outdoor temperature increases, the first coefficient has a tendency to sequentially increase; therefore, on the premise of ensuring enough refrigeration effect, the outdoor unit equipment 12 is prevented from being failed due to overlarge temperature difference between the refrigerant of the outdoor unit equipment 12 and the outdoor temperature after refrigeration.

The second coefficient in the cooling mode can be determined by table 2:

As can be determined from table 3, when the indoor unit 11 is in the cooling mode, the corresponding third coefficient is different according to the interval in which the difference between the indoor temperature and the set temperature is located. As the difference between the indoor temperature and the set temperature increases, the third coefficient has a tendency to decrease in sequence.

The first coefficient in the heating mode can be determined by table 4:

outdoor temperature (DEG C)	≤-10	-10＜≤0	＞0
				d	1.5	1.4	1.2

In addition, the above embodiments are some optional embodiments of the present invention, where the correspondence between different intervals and different coefficients may be obtained by calibration. For other embodiments of the invention, different intervals and different coefficients may be recalibrated according to different practical situations.

And, for the first coefficient, the second coefficient and the third coefficient, calibration may be performed in part in a manner similar to the above embodiment, or real-time calculation determination may be performed in specific cases.

The control method may include:

when the corrected temperature obtained by the determination is smaller than the refrigerating limit temperature, the corrected temperature is adjusted to the refrigerating limit temperature; and/or

When the corrected temperature obtained by the determination is greater than the heating limit temperature, the corrected temperature is adjusted to the heating limit temperature.

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the outdoor unit 12 is configured to: when the corrected temperature obtained by the determination is smaller than the refrigerating limit temperature, the corrected temperature is adjusted to the refrigerating limit temperature; and/or adjusting the corrected temperature to the heating limit temperature in the case where the corrected temperature obtained by the determination is greater than the heating limit temperature.

In this manner, it is advantageous to ensure the operational stability of the air conditioning system 10.

The indoor unit equipment 11 may include radiation temperature adjusting equipment. For radiation tempering devices, the tempering effect in the room can be achieved by means of heat conduction. The refrigeration limit temperature may be a minimum operating temperature of the radiant tempering device. Under the condition that the obtained correction temperature is smaller than the refrigeration limit temperature, the possibility of influencing the temperature regulating effect of the radiation temperature regulating equipment can be determined, so that the correction temperature is regulated to the refrigeration limit temperature, and the temperature regulating effect of the radiation temperature regulating equipment is ensured. The refrigeration limit temperature may be 18 ℃. The radiant tempering device may comprise a floor heating.

The outdoor unit 12 needs to perform heating and cooling effects of water by means of refrigerant heat exchange. Under the condition that the obtained correction temperature is larger than the heating limit temperature, it can be determined that the refrigerant in the outdoor unit 12 needs to exchange heat with water in a high-temperature state, and the refrigerant is always in a high-pressure state at a high temperature, so that a heat exchange pipeline in the outdoor unit 12 can be in a high-pressure state, and the risk of runaway and potential safety hazards exist, thereby adjusting the correction temperature to the heating limit temperature and ensuring that the refrigerant in the outdoor unit 12 is in a controllable range. The heating limit temperature may be 50 ℃.

On the basis of the above, the refrigerating effect of the indoor unit 11 can be ensured by setting the refrigerating limit temperature, and the runaway can be avoided by setting the heating limit temperature, thereby being beneficial to improving the operation stability of the air conditioning system 10.

The control method may include:

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the outdoor unit 12 is configured to: in the case that the number of the indoor unit devices 11 is at least two, obtaining a quasi-correction temperature corresponding to at least two indoor unit devices 11 respectively, wherein each indoor unit device 11 has a corresponding set temperature and an indoor temperature; the corrected temperature is determined based on the maximum value of at least two quasi-corrected temperatures and the temperature adjustment mode of the corresponding indoor unit equipment 11.

In this manner, multi-machine regulation of the air conditioning system 10 is facilitated.

It will be appreciated that each indoor unit 11 may be communicatively coupled to a corresponding one of the line controllers 13. The line controller 13 may determine the corrected temperature of the corresponding one of the indoor unit equipment 11 as the quasi-corrected temperature. The quasi-correction temperature of each indoor unit 11 may be the same or different.

For each quasi-corrected temperature, the temperature adjustment mode is the temperature adjustment mode of the corresponding one of the indoor units 11, the set temperature is the set temperature of the corresponding one of the indoor units 11, and the indoor temperature is the temperature in the room in which the corresponding one of the indoor units 11 is located.

The wire controller 13 may transmit the quasi-corrected temperature to the outdoor unit 12. When receiving the quasi-correction temperatures sent by the different line controllers 13, the outdoor unit 12 may determine whether to select the minimum value of the at least two quasi-correction temperatures as the correction temperature or the maximum value of the at least two quasi-correction temperatures as the correction temperature according to the temperature adjustment mode of the indoor unit 11. When the temperature adjustment mode of the indoor unit 11 is the cooling mode, the minimum value of at least two quasi-corrected temperatures is set as the corrected temperature. When the temperature adjustment mode of the indoor unit 11 is the heating mode, the maximum value of at least two quasi-corrected temperatures is set as the corrected temperature.

It will be appreciated that, in the case where the temperature adjustment mode of the indoor unit 11 is the cooling mode, the minimum value of the at least two quasi-corrected temperatures is selected as the corrected temperature, so that it is ensured that all the indoor units 11 can achieve the desired cooling requirement. In the case where the temperature adjustment mode of the indoor unit 11 is the heating mode, the maximum value of at least two quasi-corrected temperatures is selected as the corrected temperature, so that it is ensured that all the indoor units 11 can meet the desired heating requirement.

In addition, in the case where some indoor units 11 have different temperature adjustment modes, the outdoor unit 12 may satisfy the temperature adjustment requirement of the indoor unit 11 that is started earlier, and then the temperature adjustment requirement of the indoor unit 11 that is started later, or may satisfy the temperature adjustment requirement of the indoor unit 11 in the temperature adjustment mode having the largest number of indoor units 11, and then the temperature adjustment requirement of the indoor unit 11 in the temperature adjustment mode having the smaller number of indoor units 11.

The control method may include:

when the obtained correction temperature is larger than the refrigeration set temperature, the correction temperature is adjusted according to the refrigeration set temperature, and the refrigeration set temperature is the minimum value of at least two set temperatures; and/or

Thus, different indoor unit equipment 11 can be ensured to achieve corresponding temperature adjusting effects.

In the case where the number of indoor unit apparatuses 11 is at least two, the set temperature of each indoor unit apparatus 11 may be the same or may be different. When the corrected temperature obtained according to the quasi-corrected temperature is greater than the refrigeration set temperature, it may be determined that the refrigeration temperature of some indoor units 11 cannot reach the corresponding set temperature, so that the corrected temperature may be adjusted according to the refrigeration set temperature, so that all indoor units 11 needing refrigeration can reach the desired refrigeration effect. When the corrected temperature obtained according to the quasi-corrected temperature is smaller than the heating set temperature, it may be determined that there is a part of indoor unit 11 whose heating temperature cannot reach the corresponding set temperature, so that the corrected temperature may be adjusted according to the heating set temperature, so that all indoor units 11 needing heating can achieve the desired heating effect.

In the case where at least two indoor unit apparatuses 11 are in the cooling mode, the correction temperature may be adjusted according to the cooling set temperature and the first correction value. The first correction value may be-2 ℃, or the result obtained by subtracting 2 ℃ from the calculated refrigeration set temperature may be used as the corrected temperature after adjustment. The first correction value can also be selected in a corresponding value range.

In the case where at least two indoor units 11 are in the heating mode, the correction temperature may be adjusted according to the heating set temperature and the second correction value. The second correction value may be +2℃, or alternatively, a result obtained by adding 2 ℃ to the calculated heating set temperature may be used as the corrected temperature after adjustment. The second correction value can also be selected in a corresponding value range.

The control method may include:

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the wire controller 13 is configured to: and determining the correction temperature according to a preset period.

Thus, it is advantageous to ensure a sufficient temperature adjusting effect.

It can be understood that when the actual situation changes, if the user sets a new set temperature, the indoor temperature changes, the outdoor temperature changes, and part of the indoor units 11 no longer have a temperature adjustment requirement, the actual corresponding corrected temperature needs to be adjusted accordingly. The correction temperature is updated continuously according to the preset period, so that the correction temperature can be adjusted in time, so that the outdoor unit 12 can correspondingly adjust the water supply temperature, and the situation that the outdoor unit 12 still supplies water according to the non-updated correction temperature, so that the water temperature is difficult to meet the desired temperature regulation requirement (such as higher water supply temperature when refrigeration is needed and lower water supply temperature when heating is needed) or the consumption of extra energy consumption is caused can be avoided, thereby being beneficial to ensuring the sufficient temperature regulation effect. The preset period may be 120 seconds.

The control method may include:

under the condition that the temperature regulation mode of the first indoor unit 11 is inconsistent with the temperature regulation mode of the second indoor unit 11, acquiring the temperature regulation mode of the first indoor unit 11, and not responding to the temperature regulation requirement of the second indoor unit 11, wherein the first indoor unit 11 is started before the second indoor unit 11; and/or

A temperature adjustment mode having the largest number of indoor unit apparatuses 11 is acquired.

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the outdoor unit 12 is configured to: under the condition that the temperature regulation mode of the first indoor unit 11 is inconsistent with the temperature regulation mode of the second indoor unit 11, acquiring the temperature regulation mode of the first indoor unit 11, and not responding to the temperature regulation requirement of the second indoor unit 11, wherein the first indoor unit 11 is started before the second indoor unit 11; and/or a temperature regulation mode having the largest number of indoor unit apparatuses 11.

In this way, the temperature regulation requirement with higher priority can be met.

In the case where the air conditioning system 10 includes different indoor unit apparatuses 11, the different indoor unit apparatuses 11 may be in the same temperature adjustment mode or may be in different temperature adjustment modes.

The operation modes of the indoor unit 11 may include a first-on priority mode and a multiple-on priority mode.

In the first-open priority mode, according to the sequence of the sequential opening of the different indoor units 11, the outdoor opportunity preferentially responds to the temperature adjustment requirement of the indoor unit 11 (i.e. the first indoor unit 11) that is first opened, and for the indoor unit 11 (i.e. the second indoor unit 11) that is second opened, if the indoor unit 11 has a different temperature adjustment mode from the first indoor unit 11, the outdoor unit 12 still supplies water according to the temperature adjustment mode of the first indoor unit 11, but not according to the temperature adjustment mode of the second indoor unit 11, and the outdoor unit 12 does not respond to the temperature adjustment requirement of the second indoor unit 11 until the first indoor unit 11 meets the temperature adjustment requirement. The indoor unit 11 meets the temperature adjustment requirement, and the indoor temperature of the room corresponding to the indoor unit 11 can reach or basically reach the set temperature of the indoor unit 11, so that the water valve 15 corresponding to the indoor unit 11 is closed, and the indoor unit 11 enters the air supply state.

In the multi-opening priority mode, the temperature adjustment mode having the largest number of indoor units 11 may be determined as the first temperature adjustment mode according to the number of indoor units 11 in different temperature adjustment modes, and then the outdoor unit 12 may be controlled to acquire the first temperature adjustment mode without acquiring other temperature adjustment modes. For the other temperature adjustment modes, since the number of the corresponding indoor units 11 is smaller than the number of the indoor units 11 in the first temperature adjustment mode, the outdoor unit 12 does not respond to the temperature adjustment requirement of the indoor units 11 in the other temperature adjustment modes until the other temperature adjustment modes have the largest number of the indoor units 11.

The control method may include:

when the indoor temperature reaches the set temperature, it is determined to stop the supply of water to the corresponding indoor unit equipment 11.

The control method of the embodiment of the present invention may be implemented by the air conditioning system 10 of the embodiment of the present invention. Referring to fig. 2, the air conditioning system 10 is for: when the indoor temperature reaches the set temperature, it is determined to stop the supply of water to the corresponding indoor unit equipment 11.

Thus, the energy consumption is reduced.

Referring to fig. 2, the air conditioning system 10 includes a water valve 15. Each water valve 15 may be provided on one water supply pipe of the outdoor unit apparatus 12 communicating with a corresponding one of the indoor unit apparatuses 11. In the case that the indoor unit 11 is in the temperature adjustment mode, if the corresponding indoor temperature does not reach the corresponding set temperature, the air conditioning system 10 keeps the water valve 15 open, so that the indoor unit 11 continuously obtains the water supply of the outdoor unit 12 through the water supply pipeline, and if the corresponding indoor temperature reaches the corresponding set temperature, it can be determined that the indoor unit 11 has reached the corresponding temperature adjustment requirement, and the air conditioning system 10 closes the water valve 15, so that the outdoor unit 12 stops supplying water to the indoor unit 11 through the water supply pipeline, and accordingly, the load of the outdoor unit 12 can be reduced, which is beneficial to reducing energy consumption.

When the water valve 15 corresponding to the indoor unit 11 is closed, the indoor unit 11 is in the air blowing mode. In the air supply mode, the indoor unit 11 causes the indoor air to flow only by turning on the internal blower, and the corresponding line controller 13 does not determine the corrected temperature of the indoor unit 11.

In the case where all the indoor units 11 are in a state where the indoor temperature reaches the set temperature, it is determined that the outdoor unit 12 has satisfied the temperature adjustment requirements of all the indoor units 11, so that the outdoor unit 12 can be controlled to be turned off. Thus, the long-term high-load operation of the outdoor unit 12 can be avoided, and the energy efficiency of the unit can be improved.
