Description

Technical Field

[0001] The present invention relates to the technical field of energy supply, and in particular to an energy supply system and a control method thereof. Background Art

[0002] The air conditioning system includes a full air system, which is a system that completely uses air to bear the cooling and heating loads of the room. The full air air conditioning system provides cooling to the room by delivering cold air, or delivers hot air to the room to provide heat. Therefore, the full air system only needs an air handling device to process the delivered air. Therefore, the cooling and heating load control of the full air system mainly controls the air handling device, which is relatively simple.

[0003] The overall volume of the air handling device in the current full air system is relatively large, and generally requires an independent equipment room for storage, which makes it impossible to popularize it in ordinary houses with limited area and limited number of rooms. Therefore, many companies are currently starting to develop new energy supply systems. This type of energy supply system has both a first heat exchange unit for outputting regulated air and a second heat exchange unit for outputting regulated water to adjust the temperature of the space to be regulated. Therefore, the energy supply system not only controls the first heat exchange unit to output air at a reasonable temperature, but also controls the second heat exchange unit to output water at a reasonable temperature. Therefore, a new control method is needed for this energy supply system to meet usage requirements. Summary of the invention

[0083] In order to independently control the air outlet temperature and the water outlet temperature of the energy supply device according to the target parameters of the space to be regulated, thereby meeting the load demand of the space to be regulated, a control method for an energy supply system is proposed in the present application. Figure 1 The steps of the control method of the energy supply system in the embodiment of the present invention are as follows: Figure 1 ,like Figure 1 As shown, the control method of the energy supply system may include the following steps:

[0084] S101: receiving real-time parameters of each space to be regulated and target parameters of each space to be regulated, wherein the real-time parameters of the space to be regulated at least include the temperature of the space to be regulated.

[0085] In this step, the terminal equipment 3 and / or the air supply terminal 4 of the energy supply system are installed in each space that needs to be adjusted. The energy supply device 1 in the energy supply system can receive the real-time parameters of each space that needs to be adjusted and the target parameters of each space that needs to be adjusted in various ways, wherein the target parameters of each space that needs to be adjusted refer to the target parameters set by the user that the space needs to be adjusted to through the energy supply system. The real-time parameters of the space that needs to be adjusted include at least the temperature of the space that needs to be adjusted, and may also include the humidity, carbon dioxide concentration, etc. of the space that needs to be adjusted. Similarly, the target parameters may include the target temperature of the space that needs to be adjusted, and may also include the target humidity, target carbon dioxide concentration, etc. of the space that needs to be adjusted.

[0086] A control box can be installed in each space to be adjusted, and the control box can collect real-time parameters of the space. At the same time, the user can adjust the target parameters of the space on the control box. The control box can communicate with the energy supply device 1 wirelessly or by wire, such as by power line communication or by special cables.

[0087] After receiving the real-time parameters of each space to be regulated and the target parameters of each space to be regulated, the operation mode of the energy supply system is determined according to one or more of the following factors, which may include the installation conditions of the air supply terminals and the terminal devices 3 in each space to be regulated, the specific conditions of the temperature regulation required for each space to be regulated, the special mode selected by the user, the real-time parameters of each space to be regulated, and the target parameters of each space to be regulated. The operation mode of the energy supply system may include: adjusting the real-time parameters of each space to be regulated only through the air supply terminal 4; adjusting the real-time parameters of each space to be regulated only through the terminal device 3; adjusting the real-time parameters of each space to be regulated through the air supply terminal 4 and the terminal device 3 at the same time. If it is determined that the real-time parameters of each space to be regulated need to be adjusted through the air supply terminal 4 and the terminal device 3 at the same time, the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 need to be determined subsequently.

[0088] S102: Obtaining the air outlet temperature of the energy supply device 1 according to the real-time parameters of each space to be regulated and the target parameters of each space to be regulated.

[0089] According to the real-time parameters of each space to be adjusted and the target parameters of each space to be adjusted, it can be determined which real-time parameters of the space to be adjusted do not meet the corresponding target parameters. If they do not meet the target parameters, it is necessary to adjust the parameters through the terminal device 3 and / or the air supply terminal 4 in the energy supply system in the space to be adjusted. If the terminal device 3 and / or the air supply terminal 4 in the energy supply system in the space to be adjusted can adjust the parameters of the space to be adjusted by air supply, it is necessary to determine the air outlet temperature of the energy supply device 1. In other words, the air output after heat exchange by the first heat exchange unit 14 of the energy supply device 1 is input into the space to be adjusted through the air supply terminal 4 in the form of air supply.

[0090] In this step, when the energy supply system is in a cooling state, the air outlet temperature of the energy supply device 1 is determined according to the lowest temperature parameter among the target parameters of each space to be adjusted. When the energy supply system is in a heating state, the air outlet temperature of the energy supply device 1 is determined according to the highest temperature parameter among the target parameters of each space to be adjusted. The above-mentioned method can ensure that the parameters of all spaces that need to be adjusted can eventually be adjusted to the target parameters. As feasible, in order to speed up the adjustment of the parameters in the space that needs to be adjusted under the premise of the same air supply volume, when the energy supply system is in a cooling state, the air outlet temperature of the energy supply device 1 is generally lower than the lowest temperature parameter among the target parameters of each space that needs to be adjusted. Similarly, when the energy supply system is in a heating state, the air outlet temperature of the energy supply device 1 is higher than the highest temperature parameter among the target parameters of each space that needs to be adjusted.

[0091] S103: Obtaining the outlet water temperature of the energy supply device 1 according to the real-time parameters of each space to be adjusted and the target parameters of each space to be adjusted.

[0092] Similarly, according to the real-time parameters of each space to be adjusted and the target parameters of each space to be adjusted, it can be determined which real-time parameters of the space to be adjusted do not meet the corresponding target parameters. If they do not meet the target parameters, it is necessary to adjust the parameters through the terminal device 3 and / or the air supply terminal 4 in the energy supply system in the space to be adjusted. If the terminal device 3 in the energy supply system in the space to be adjusted can adjust the parameters of the space to be adjusted by water supply, it is necessary to determine the outlet water temperature of the energy supply device 1. In other words, the water output after heat exchange by the second heat exchange unit 15 of the energy supply device 1 is input into the terminal device 3 in the space to be adjusted by water supply.

[0093] In this step, when the energy supply system is in a cooling state, the outlet water temperature of the energy supply device 1 is determined according to the lowest temperature parameter among the target parameters of each space to be adjusted. When the energy supply system is in a heating state, the outlet water temperature of the energy supply device 1 is determined according to the highest temperature parameter among the target parameters of each space to be adjusted. The above-mentioned method can ensure that the parameters of all spaces that need to be adjusted can eventually be adjusted to the target parameters. As feasible, in order to speed up the speed of adjusting the parameters in the space that needs to be adjusted, when the energy supply system is in a cooling state, the outlet water temperature of the energy supply device 1 is generally lower than the lowest temperature parameter among the target parameters of each space that needs to be adjusted. Similarly, when the energy supply system is in a heating state, the outlet water temperature of the energy supply device 1 is higher than the highest temperature parameter among the target parameters of each space that needs to be adjusted.

[0094] S104: Control the output power of the compressor according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1, and the compressor is used to supply refrigerant to the first heat exchange unit 14 for adjusting the outlet air temperature and the second heat exchange unit 15 for adjusting the outlet water temperature.

[0095] In this step, based on the known performance and conditions of the first heat exchange unit 14, the second heat exchange unit 15 and the compressor in the energy supply device 1, the output power of the compressor can be roughly determined according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1. In a feasible implementation, for example, when the energy supply system is in a cooling state, Figure 2 The steps of the control method of the energy supply system in the embodiment of the present invention are as follows: Figure 2 ,like Figure 2 As shown, controlling the output power of the compressor according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 may include the following steps:

[0096] S201: Determine the evaporation temperature of the refrigerant in the first heat exchange unit 14 according to the outlet air temperature of the energy supply device 1.

[0097] In this step, the evaporation temperature of the refrigerant in the first heat exchange unit 14 needs to be lower than the outlet air temperature of the energy supply device 1, ensuring that the air flowing through the first heat exchange unit 14 can reach the outlet air temperature of the energy supply device 1 after heat exchange with the refrigerant. The specific temperature can be determined based on the heat exchange performance of the first heat exchange unit 14.

[0098] S202: Determine the evaporation temperature of the refrigerant in the second heat exchange unit 15 according to the outlet water temperature of the energy supply device 1.

[0099] In this step, the evaporation temperature of the refrigerant in the second heat exchange unit 15 needs to be lower than the water outlet temperature of the energy supply device 1, ensuring that the water flowing through one channel in the second heat exchange unit 15 can reach the water outlet temperature of the energy supply device 1 after heat exchange with the refrigerant flowing through another channel in the second heat exchange unit 15. The specific temperature can be determined based on the heat exchange performance of the second heat exchange unit 15.

[0100] S203: Obtain a first temperature according to the evaporation temperature of the refrigerant in the first heat exchange unit 14 and the evaporation temperature of the refrigerant in the second heat exchange unit 15.

[0101] In this step, the minimum value between the evaporation temperature of the refrigerant in the first heat exchange unit 14 and the evaporation temperature of the refrigerant in the second heat exchange unit 15 can be selected as the first temperature, so as to ensure that the output power of the compressor is large enough to fully meet the refrigeration demand.

[0102] S204: Obtain the output power of the compressor according to the first temperature.

[0103] Based on the known performances and conditions of the first heat exchange unit 14, the second heat exchange unit 15 and the compressor in the energy supply device 1 itself, the output power of the compressor can be roughly determined according to the first temperature.

[0104] Of course, when the energy supply system is in the heating state, the output power of the compressor can also be determined by the above-mentioned similar method process. The step of controlling the output power of the compressor according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 may include: determining the condensation temperature of the refrigerant in the first heat exchange unit 14 according to the outlet air temperature of the energy supply device 1; determining the condensation temperature of the refrigerant in the second heat exchange unit 15 according to the outlet water temperature of the energy supply device 1; obtaining the first temperature according to the condensation temperature of the refrigerant in the first heat exchange unit 14 and the condensation temperature of the refrigerant in the second heat exchange unit 15; and obtaining the output power of the compressor according to the first temperature. Correspondingly, as feasible, the maximum value of the condensation temperature of the refrigerant in the first heat exchange unit 14 and the condensation temperature of the refrigerant in the second heat exchange unit 15 can be used as the first temperature, so as to ensure that the output power of the compressor is large enough to fully meet the heating demand.

[0105] As feasible, in order to further ensure the accuracy and precision of the output power of the compressor, the output power of the compressor can be corrected again. Therefore, the step of controlling the output power of the compressor according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 may include:

[0106] S205: Detect and obtain the actual air outlet temperature of the energy supply device 1 and / or the actual water outlet temperature of the energy supply device 1 .

[0107] If the energy supply device 1 adjusts the parameters of the space to be adjusted by discharging air, the actual outlet air temperature of the energy supply device 1 can be detected. If the energy supply device 1 adjusts the parameters of the space to be adjusted by discharging water, the actual outlet water temperature of the energy supply device 1 can be detected.

[0108] S206: Correct the first temperature according to the relationship between the actual air outlet temperature of the energy supply device 1 and the air outlet temperature of the energy supply device 1 and / or the relationship between the actual water outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 to obtain a corrected first temperature.

[0109] In this step, as feasible, the first temperature can be corrected according to the difference between the actual air outlet temperature of the energy supply device 1 and the air outlet temperature of the energy supply device 1 and / or the difference between the actual water outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 to obtain a corrected first temperature.

[0110] Furthermore, when the energy supply system is in a cooling state, when the difference between the actual outlet air temperature of the energy supply device 1 and the outlet air temperature of the energy supply device 1 is a positive number, the corrected first temperature decreases, and the larger the positive number is, the lower the degree of decrease of the corrected first temperature is. When the difference between the actual outlet air temperature of the energy supply device 1 and the outlet air temperature of the energy supply device 1 is a negative number, the corrected first temperature increases, and the smaller the negative number is, the greater the degree of increase of the corrected first temperature is.

[0111] When the difference between the actual outlet water temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 is a positive number, the corrected first temperature decreases, and the larger the positive number is, the greater the degree of decrease of the corrected first temperature is. When the difference between the actual outlet water temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 is a negative number, the corrected first temperature increases, and the smaller the negative number is, the greater the degree of increase of the corrected first temperature is.

[0112] When the energy supply system is in the heating state, when the difference between the air outlet temperature of the energy supply device 1 and the actual air outlet temperature of the energy supply device 1 is a positive number, the corrected first temperature increases, and the larger the positive number is, the larger the corrected first temperature increases. When the difference between the air outlet temperature of the energy supply device and the actual air outlet temperature of the energy supply device is a negative number, the corrected first temperature decreases, and the smaller the negative number is, the greater the degree of decrease of the corrected first temperature. When the difference between the water outlet temperature of the energy supply device 1 and the actual water outlet temperature of the energy supply device 1 is a positive number, the corrected first temperature increases, and the larger the positive number is, the greater the degree of increase of the corrected first temperature. When the difference between the water outlet temperature of the energy supply device and the actual water outlet temperature of the energy supply device is a negative number, the corrected first temperature decreases, and the smaller the negative number is, the greater the degree of decrease of the corrected first temperature.

[0113] For example, when the energy supply system is in a cooling state, if the actual air outlet temperature of the energy supply device 1 is larger than the air outlet temperature of the energy supply device 1, it means that the output power of the compressor is insufficient, and the first temperature needs to be lowered and corrected to obtain a corrected first temperature. Similarly, if the actual water outlet temperature of the energy supply device 1 is larger than the water outlet temperature of the energy supply device 1, it means that the output power of the compressor is insufficient, and the first temperature needs to be lowered and corrected to obtain a corrected first temperature. If the actual air outlet temperature of the energy supply device 1 is insufficient, and the actual water outlet temperature of the energy supply device 1 is also insufficient, the lower of the two corrected first temperatures is taken as the final first temperature.

[0114] When the energy supply system is in the heating state, on the contrary, the higher of the two corrected first temperatures is taken as the final first temperature.

[0115] S207: Adjust the output power of the compressor according to the corrected first temperature.

[0116] Steps S206 to S207 can be continuously executed in a loop as needed until the difference between the actual air outlet temperature of the energy supply device 1 and the air outlet temperature of the energy supply device 1 is small or basically equal, and the difference between the actual water outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 is small or basically equal, which meets the requirements.

[0117] S105: Control the opening of the first throttling unit 16 corresponding to the first heat exchange unit 14 and the opening of the second throttling unit 17 corresponding to the second heat exchange unit 15 according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1 .

[0118] The refrigerant compressed by the compressor needs to flow through the first heat exchange unit 14 and the second heat exchange unit 15. The first throttling unit 16 is used to throttle the refrigerant flowing into the first flow channel 141 of the first heat exchange unit 14 to control the superheat of the refrigerant. The second throttling unit 17 is used to throttle the refrigerant flowing into the second flow channel 151 of the second heat exchange unit 15 to control the superheat of the refrigerant. In this way, the degree of heat exchange between the refrigerant flowing into the first flow channel 141 and the air flowing through the first heat exchange unit 14 can be controlled, thereby controlling the outlet air temperature of the energy supply device 1. The degree of heat exchange between the refrigerant flowing into the second flow channel 151 of the second heat exchange unit 15 and the water flowing through the third flow channel 152 of the second heat exchange unit 15 can be controlled, thereby controlling the outlet water temperature of the energy supply device 1. Therefore, it is necessary to control the opening of the first throttling unit 16 corresponding to the first heat exchange unit 14 and the opening of the second throttling unit 17 corresponding to the second heat exchange unit 15 according to the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1, so that the actual air outlet temperature of the energy supply device 1 and the actual water outlet temperature of the energy supply device 1 meet their respective different requirements.

[0119] As a feasible example, the energy supply system is in a cooling state. When the energy supply system is in a cooling state, Figure 3 The steps of the control method of the energy supply system in the embodiment of the present invention are as follows: Figure 3 ,like Figure 3 As shown, in a specific implementation, the following steps may be included:

[0120] S301: Initialization operation, adjusting the opening of the first throttling unit 16 so that the superheat of the refrigerant flowing through the first heat exchange unit 14 is at a first preset value, and adjusting the opening of the second throttling unit 17 so that the superheat of the refrigerant flowing through the second heat exchange unit 15 is at a second preset value.

[0121] In this step, the first preset value and the second preset value can be an arbitrary value that is initially set. For example, when the energy supply system is in a cooling state, the superheat of the refrigerant of the first heat exchange unit 14 is equal to the refrigerant temperature (Tf2) at the outlet of the first flow channel 141 of the first heat exchange unit 14 minus the refrigerant temperature (Tf1) at the inlet of the first flow channel 141 of the first heat exchange unit 14. The superheat of the refrigerant of the second heat exchange unit 15 is equal to the refrigerant temperature (Tp2) at the outlet of the second flow channel 151 of the second heat exchange unit 15 minus the refrigerant temperature (Tp1) at the inlet of the second flow channel 151 of the second heat exchange unit 15.

[0122] S302: The first preset value and the second preset value are corrected according to the difference between the evaporation temperature of the refrigerant in the first heat exchange unit 14 and the evaporation temperature of the refrigerant in the second heat exchange unit 15, so as to adjust the opening of the first throttling unit 16 so that the superheat of the refrigerant flowing through the first heat exchange unit 14 is at the corrected first preset value, and adjust the opening of the second throttling unit 17 so that the superheat of the refrigerant flowing through the second heat exchange unit 15 is at the corrected second preset value.

[0123] In this step, the difference between the evaporation temperature of the refrigerant in the first heat exchange unit 14 and the evaporation temperature of the refrigerant in the second heat exchange unit 15 can be used to determine which of the first heat exchange unit 14 and the second heat exchange unit 15 has a greater cooling load demand, thereby correcting the initial first preset value and the second preset value. Thereafter, the opening of the first throttling unit 16 is adjusted so that the superheat of the refrigerant flowing through the first heat exchange unit 14 is at the corrected first preset value, and the opening of the second throttling unit 17 is adjusted so that the superheat of the refrigerant flowing through the second heat exchange unit 15 is at the corrected second preset value.

[0124] As a feasible method, the first correction value and the second correction value can be obtained according to the difference between the evaporation temperature of the refrigerant in the first heat exchange unit 14 and the evaporation temperature of the refrigerant in the second heat exchange unit 15; the first preset value and the first correction value are added to obtain the corrected first preset value; the second preset value and the second correction value are added to obtain the corrected second preset value.

[0125] Specifically, if the evaporation temperature of the refrigerant in the first heat exchange unit 14 is greater than the evaporation temperature of the refrigerant in the second heat exchange unit 15, the first correction value is greater than the second correction value. If the evaporation temperature of the refrigerant in the first heat exchange unit 14 is less than the evaporation temperature of the refrigerant in the second heat exchange unit 15, the first correction value is less than the second correction value.

[0126] In order to further ensure that the actual air outlet temperature of the energy supply device 1 reaches the air outlet temperature of the energy supply device 1, the first preset value may be corrected again. As a feasible method, the following steps may be included:

[0127] S303: Detect and obtain the actual air outlet temperature of the energy supply device 1, and correct the first preset value according to the relationship between the actual air outlet temperature of the energy supply device 1 and the air outlet temperature of the energy supply device 1, thereby adjusting the opening of the first throttling unit 16 so that the superheat of the refrigerant flowing through the first heat exchange unit 14 is at the corrected first preset value.

[0128] For example, when the energy supply system is in a cooling state and the actual air outlet temperature of the energy supply device 1 is higher than the air outlet temperature of the energy supply device 1 , the first preset value is corrected to decrease.

[0129] Similarly, in order to further ensure that the actual outlet water temperature of the energy supply device 1 reaches the outlet water temperature of the energy supply device 1, the second preset value may be corrected again. As a feasible method, the following steps may be included:

[0130] S304: Detect and obtain the actual water outlet temperature (Tw2) of the energy supply device 1, and correct the second preset value according to the relationship between the actual water outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1, thereby adjusting the opening of the second throttling unit 17 so that the superheat of the refrigerant flowing through the second heat exchange unit 15 is at the corrected second preset value.

[0131] For example, when the energy supply system is in a cooling state, when the actual water outlet temperature of the energy supply device 1 is higher than the water outlet temperature of the energy supply device 1, the second preset value is corrected to be decreased; when the actual water outlet temperature of the energy supply device 1 is lower than the water outlet temperature of the energy supply device 1, the second preset value is corrected to be increased.

[0132] Through step S303 and step S304, the actual air outlet temperature of the energy supply device 1 can finally reach the air outlet temperature of the energy supply device 1, and the actual water outlet temperature of the energy supply device 1 can reach the water outlet temperature of the energy supply device 1.

[0133] When the energy supply system is in the heating state, the specific implementation of step S105 may be similar to the above steps and will not be described in detail here.

[0134] As a feasible method, the control method of the energy supply system may include: when the convection type terminal device 3 is in operation, the radiation type terminal device 3 may be turned off. Since the convection type terminal device 3 is faster in adjusting the parameters of the space to be adjusted, the convection type terminal device 3 may be preferentially selected to adjust the parameters of the space to be adjusted. In particular, when the space to be adjusted has both a convection type terminal device 3 and a radiation type terminal device 3, the convection type terminal device 3 may be preferentially selected to adjust the parameters of the space to be adjusted. In addition, even if the convection type terminal device 3 and the radiation type terminal device 3 adjust the parameters of the same space to be adjusted, due to their respective inherent characteristics, the water temperature required by the convection type terminal device 3 is completely different from the water temperature required by the radiation type terminal device 3. Therefore, staggered operation of the two facilitates the control of the outlet water temperature of the energy supply device 1.

[0135] The water output from the second heat exchange unit 15 is used to supply the terminal device 3, that is, the water output from the third flow channel 152 of the second heat exchange unit 15 is used to supply the terminal device 3, and the terminal device 3 may include a radiation type terminal device 3 and a convection type terminal device 3. Among them, the radiation type terminal device 3 is a terminal device 3 that mainly uses radiation heat exchange to exchange heat with the air of the space to be regulated, so as to adjust the parameters of the space to be regulated. For example, the radiation type terminal device 3 may include at least one of the following: floor heating, wall heating, capillary network, etc. The convection type terminal device 3 is a terminal device 3 that mainly uses convection heat exchange to exchange heat with the air of the space to be regulated, so as to adjust the parameters of the space to be regulated. For example, the convection type terminal device 3 may include at least one of the following: fan coil, chilled beam, air conditioner indoor unit, etc.

[0136] Correspondingly, in step S103, the following steps may be included:

[0137] Determine whether the convection type terminal device 3 is running;

[0138] If so, the outlet water temperature of the energy supply device 1 is obtained according to the target parameter of the space to be regulated corresponding to the convection type terminal device 3. Further, when the energy supply system is in the cooling state, the outlet water temperature of the energy supply device 1 is determined according to the lowest temperature parameter among the target parameters of the space to be regulated corresponding to the convection type terminal device 3. When the energy supply system is in the heating state, the outlet water temperature of the energy supply device 1 is determined according to the highest temperature parameter among the target parameters of the space to be regulated corresponding to the convection type terminal device 3.

[0139] If not, the outlet water temperature of the energy supply device 1 is obtained according to the target parameter of the space to be regulated corresponding to the radiation type terminal device 3. Further, when the energy supply system is in the cooling state, the outlet water temperature of the energy supply device 1 is determined according to the highest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3. When the energy supply system is in the heating state, the outlet water temperature of the energy supply device 1 is determined according to the highest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3.

[0140] As feasible, if not, the water outlet temperature of the energy supply device 1 can also be obtained according to the target parameters of the space to be regulated corresponding to the radiation type terminal device 3 and / or the air dew point temperature in the corresponding space to be regulated. When the energy supply system is in a cooling state, the water outlet temperature of the energy supply device 1 can be adjusted and changed according to the change of the air dew point temperature of the corresponding space to be regulated, and the air dew point temperature is the air dew point temperature in the corresponding space to be regulated. When the highest temperature parameter in the target parameters of the space to be regulated corresponding to the radiation type terminal device 3 is lower than the highest air dew point temperature in the corresponding space to be regulated, the water outlet temperature of the energy supply device 1 needs to be determined according to the highest air dew point temperature in the corresponding space to be regulated. For example, in order to prevent water vapor in the air from turning into dewdrops and condensing on the surface of the radiation type terminal device 3 or the surface of the wall in which the radiation type terminal device 3 is buried, the water outlet temperature of the energy supply device 1 can be slightly greater than or equal to the highest air dew point temperature in the corresponding space to be regulated. When the highest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3 is higher than the highest air dew point temperature in the corresponding space to be regulated, and some temperature parameters among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3 are lower than the highest air dew point temperature in the corresponding space to be regulated, the water outlet temperature of the energy supply device 1 can be determined according to the highest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3.

[0141] When the lowest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3 is higher than the highest air dew point temperature in the corresponding space to be regulated, the outlet water temperature of the energy supply device 1 can be determined according to the lowest temperature parameter among the target parameters of the space to be regulated corresponding to the radiation type terminal device 3. However, in the actual operation of the energy supply system, the probability of this situation occurring is very low.

[0142] Since the target parameters of a space to be regulated will continue to change after cold air is input into the air supply terminal 4, for example, the temperature and humidity in the target parameters of the space to be regulated will decrease, and therefore, the air dew point temperature in the space to be regulated is constantly changing. Therefore, the water outlet temperature of the energy supply device 1 can be adjusted and changed according to the change of the air dew point temperature of the corresponding space to be regulated. The control method of the energy supply system in the present application obtains the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 according to the real-time parameters of each space to be regulated and the target parameters of each space to be regulated, and first calculates the output power of the compressor based on the two, so that the output power of the compressor first meets the needs of the energy supply device 1. Afterwards, by controlling the opening of the first throttling unit 16 corresponding to the first heat exchange unit 14 and the opening of the second throttling unit 17 corresponding to the second heat exchange unit 15 according to the outlet air temperature of the energy supply device 1 and the outlet water temperature of the energy supply device 1, the cold or heat carried by the refrigerant output by the compressor is reasonably distributed to the first heat exchange unit 14 and the second heat exchange unit 15, so that the actual outlet air temperature of the energy supply device 1 formed after heat exchange by the air flowing through the first heat exchange unit 14 reaches the outlet air temperature of the energy supply device 1, and the actual outlet water temperature of the energy supply device 1 formed after heat exchange between the water passing through the third flow channel 152 of the second heat exchange unit 15 and the refrigerant flowing into the second flow channel 151 of the second heat exchange unit 15 reaches the outlet water temperature of the energy supply device 1. In this way, the real-time parameters of each space to be adjusted can be adjusted to the target parameters as soon as possible to meet the user's usage needs.

[0143] The control method of the energy supply system in the present application can take into account the two parameters of the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 at the same time, and couple the two to determine the final output power of the compressor. In addition, the opening of the first throttling unit 16 corresponding to the first heat exchange unit 14 and the opening of the second throttling unit 17 corresponding to the second heat exchange unit 15 are controlled by the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1, so that the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 can be independently controlled, thereby meeting the different requirements of the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1, and at the same time, the stability of the air outlet temperature of the energy supply device 1 and the water outlet temperature of the energy supply device 1 can be ensured.

[0144] Figure 4 FIG. 1 is a schematic diagram of the structure of an energy supply system in an embodiment of the present invention in a feasible implementation manner. Figure 4 As shown, the energy supply system using the above control method may include an energy supply device 1 and a compressor and heat exchanger system 2. Figure 5FIG. 1 is a schematic diagram of an energy supply device in an embodiment of the present invention in a feasible implementation manner, as shown in FIG.

The compressor and heat exchanger system 2 is used to supply the treated refrigerant to the first flow channel 141 and the second flow channel 151. The compressor and heat exchanger system 2 may include a compressor. The return air inlet 11 and the fresh air inlet 12 may each be provided with an air valve 19 as required to adjust the flow of the return air volume and the fresh air volume.

[0145] The first flow channel 141 can adjust the temperature and / or humidity of the gas flowing into the fresh air inlet 12 and / or the return air inlet 11 and flowing out of the air outlet 13. The gas may include air. The return air inlet 11 may be directly or indirectly connected to the space to be regulated.

[0146] As feasible, Figure 5 As shown, the energy supply device 1 may include: a driving pump 20, which is connected to the third flow channel 152, and is used to drive the heat exchange medium in the third flow channel 152 to flow to the terminal device 3. The heat exchange medium after heat exchange in the terminal device 3 can flow back to the other end of the third flow channel 152.

[0147] As feasible, Figure 5 As shown, the energy supply device 1 may include: an air supply module 18, which is used to output the air flowing into the return air port 11 and / or the fresh air port 12 to the air outlet 13 for outlet. The air supply module 18 may include at least a fan.

[0148] Further, such as Figure 4As shown, the energy supply system may include: at least one air supply terminal 4, which can be connected to the air outlet 13 of the energy supply device 1; at least one terminal device 3, and the third flow channel 152 is used to supply the heat exchange medium after heat exchange treatment, such as water, to the terminal device 3. Each space to be regulated can be installed with an air supply terminal 4 and / or a terminal device 3 accordingly. The air supply terminal 4 is used to receive the regulated gas output from the air outlet 13.

[0149] like Figure 4 As shown, when there are multiple air supply terminals 4, the energy supply system may include an air distribution box 5, the inlet of the air distribution box 5 is connected to the air outlet 13 of the energy supply device 1, and the air distribution box 5 has multiple outlets, and at least some of the outlets of the air distribution box 5 are provided with air valves 19. The outlets of the air distribution box 5 are respectively connected to the corresponding air supply terminals 4. The air supply terminal 4 may include an air supply box. As feasible, the air supply box may have a muffler function.

[0150] As a feasible method, the air volume detection device may be provided in the air distribution box 5, and the air volume detection device is used to detect the air volume output from the outlet of the air distribution box 5.

[0151] like Figure 5 As shown, as feasible, the compressor and heat exchanger system 2 can be connected to the first flow channel 141 and the second flow channel 151 connected in parallel. The first throttling unit 16 is located on the first flow channel 141, and the second throttling unit 17 is located on the second flow channel 151.

[0152] As feasible, Figure 6 FIG. 1 is a schematic diagram of the second flow channel and the first flow channel in the second implementation mode in an embodiment of the present invention. Figure 6 As shown, the two ends of the second flow channel 151 and the first flow channel 141 after being connected in series can be connected to the compressor and the heat exchange system. A first throttling unit 16 is provided at the inlet of the first flow channel 141, and a second throttling unit 17 is provided at the inlet of the second flow channel 151. The first throttling unit 16 and the second throttling unit 17 may include an electronic expansion valve. By controlling the electronic expansion valve, it is realized whether the refrigerant entering the inlet of the second flow channel 151 and the first flow channel 141 is throttled and depressurized. If the corresponding flow channel needs to be heat exchanged, the electronic expansion valve at the inlet of the flow channel is controlled to play a throttling and depressurizing function on the refrigerant flowing through. Specifically, according to the amount of heat exchange required, the degree to which the electronic expansion valve plays a throttling and depressurizing role on the refrigerant flowing through is controlled. In the above manner, the cooling capacity can also be distributed to the second flow channel 151 and the first flow channel 141.

[0153] As feasible, Figure 7 FIG. 1 is a schematic diagram of the second flow channel and the first flow channel in a third implementation mode in an embodiment of the present invention. Figure 7As shown, one end of the compressor and heat exchange system is connected to the first on-off valve 21 and then connected to the other end of the compressor and heat exchange system through the first channel 22, and the first channel 22 includes a second flow channel 151 and a second on-off valve 23 connected to the other end; one end of the compressor and heat exchange system is connected to the first on-off valve 21 and then connected to the other end of the compressor and heat exchange system through the second channel 24, and the second channel 24 includes a first flow channel 141, the first channel 22 and the second channel 24 are connected in parallel, the first channel 22 has a first throttling unit 16, and the second channel 24 has a second throttling unit 17; one end of the compressor and heat exchange system is connected to the first channel 22 between the second on-off valve 23 and the second flow channel 151 through a third channel 25, and the third channel 25 has a third on-off valve 26. By controlling the on-off of the first on-off valve 21, the second on-off valve 23 and the third on-off valve 26, the second flow channel 151 and the first flow channel 141 can be connected in parallel. Specifically, the first on-off valve 21 and the second on-off valve 23 are in an open state, and the third on-off valve 26 is in a closed state. At this time, the refrigerant input to the second flow channel 151 and the first flow channel 141 by the compressor and the heat exchange system can be distributed through the first throttling unit 16 and the second throttling unit 17. In this embodiment, the second flow channel 151 and the first flow channel 141 can also be connected in series. Specifically, the first on-off valve 21 and the second on-off valve 23 are in a closed state, and the third on-off valve 26 is in an open state. When the second flow channel 151 and the first flow channel 141 are connected in series and it is necessary to distribute the heat exchange medium input to the second flow channel 151 and the first flow channel 141 by the compressor and the heat exchange system, an electronic expansion valve is required in the compressor and the heat exchange system or on the third flow channel 152. The electronic expansion valve is located upstream of the second flow channel 151. The refrigerant enters the second flow channel 151 after passing through the electronic expansion valve and the third flow channel 152, and then enters the first flow channel 141 after passing through the first throttling unit 16 and the second throttling unit 17 and then returns to the compressor and the heat exchange system. When the second flow channel 151 and the first flow channel 141 are connected in series, the isothermal dehumidification function can be realized for the same space. The liquid refrigerant with a higher temperature output by the compressor and the heat exchange system passes through the second flow channel 151, and the terminal device 3 can output heat to the space to be regulated at this time; thereafter, the liquid refrigerant with a higher temperature passes through the first throttling unit 16 and the second throttling unit 17 for throttling and cooling to at least partially become a gaseous state, and the cooled refrigerant passes through the first flow channel 141 to cool and dehumidify the gas flowing through it, and the cooled and dehumidified gas is input into the above-mentioned same space to be regulated through the air outlet 13 and the air supply terminal 4, and the cooled gas is neutralized with the heat input by the terminal device 3, so that the basic temperature of the gas in the same space to be regulated can be maintained, but its humidity is effectively reduced, thereby realizing the isothermal dehumidification function.

[0154] In all the above embodiments, as feasible, both the first throttling unit 16 and the second throttling unit 17 may adopt electronic expansion valves.
