Description

[0002] Promoting the full electrification of urban heating is an effective way to achieve clean and low-carbon heating. Driven by electricity, air source heat pumps absorb heat from the air through the evaporator and then release the heat through the condenser. They are highly efficient, energy-saving and environmentally friendly.

[0003] The heating coefficient of an air-source heat pump is affected by ambient temperature. The lower the ambient temperature, the lower the heating coefficient. Furthermore, operating at low ambient temperatures can lead to a sharp drop in compressor reliability, increased failure rates, and even malfunction. Cascade heat pumps have been used to address the issue of heat pump failure in low-temperature environments. However, cascade heating systems are complex to control and exhibit poor variable operating performance.

DETAILED DESCRIPTION

[0030] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] Promoting the full electrification of urban heating is an effective way to achieve clean, low-carbon heating. Air-source heat pumps, driven by electricity, absorb heat from the air through an evaporator and release it through a condenser, making them highly efficient, energy-efficient, and environmentally friendly. The heating coefficient of an air-source heat pump is affected by ambient temperature; the lower the ambient temperature, the lower the heating coefficient. Furthermore, operating at low ambient temperatures can significantly reduce compressor reliability, increase failure rates, and even lead to malfunction.

[0032] In some cases, cascade heat pumps can address the issue of heat pump failure in low-temperature environments. However, cascade heating systems are complex to control and have poor variable-condition performance. High ambient temperatures at the beginning and end of a heating cycle can deviate from design operating conditions, leading to lower heating system efficiency.

[0033] Based on this, the present application proposes an air source water cascade heating system and operation method, which can determine the hot water flow and water supply temperature required by the heating system according to the outdoor climate conditions, and then determine the operation mode of the air source water cascade heat pump, that is, whether the low temperature stage alone is used for heating or the low temperature stage and the high temperature stage are used for cascade heating, which has better adaptability and is more in line with actual working conditions.

[0034] Figure 1It is a schematic diagram of a heating system according to an embodiment of the present application.

[0035] As an example, Figure 1 As shown, the heating system 1000 includes: a first heat pump module 100 and a second heat pump module 200, the first heat pump module 100 and the second heat pump module 200 being configured to heat the user's return water; a pipe module 300, the pipe module 300 being connected to the first heat pump module 100, the second heat pump module 200, and the user end 400, the pipe module 300 being configured to provide the user's return water to the first heat pump module 100 and / or the second heat pump module 200, and to provide the heated supply water to the user end 400; a control module 500, the control module 500 being connected to the pipe module 300, the control module 500 being configured to determine the operation mode of the heating system according to user information and environmental information; wherein the operation mode includes a cascade operation mode and a low-temperature operation mode, in which the first heat pump module 100 and the second heat pump module 200 are both in operation, and in the low-temperature operation mode, the first heat pump module 100 is in operation.

[0036] For example, the first heat pump module 100 and the second heat pump module 200 form a cascade heat pump heating system. Both the first and second heat pump modules 100 and 200 are used to heat user return water. The pipe module 300 is connected to the user terminal 400, recovering the user return water and providing it to the first heat pump module 100 and / or the second heat pump module 200. It is understood that the user return water can be provided to the first heat pump module 100 for heating, or provided to the second heat pump module 200 for heating. The heated water is then re-supplied to the user terminal 400 via the pipe module 300, thus achieving a circulating heat supply. The pipe module 300 is connected to the control module 500, which can be a host computer that centrally controls the devices in the heating system 1000, for example, controlling the opening and closing of valves in the pipe module 300.

[0037] For example, the present application utilizes an algorithm to implement a heat pump control system that comprehensively considers heat user characteristics and local climate conditions. The control module 500 obtains user information and environmental information, such as the user's building type and age, and environmental information such as ambient temperature and humidity. The present application optimizes the control algorithm to determine the operating mode of the heating system 1000 based on the user information and environmental information. The operating modes of the heating system 1000 include a cascade operating mode and a low-temperature operating mode. In the cascade operating mode, both the first heat pump module 100 and the second heat pump module 200 operate. In the low-temperature operating mode, the first heat pump module 100 operates. It can be understood that the first heat pump module 100 is a low-temperature heat pump module, and the second heat pump module 200 is a high-temperature heat pump module. In the cascade operating mode, both the first heat pump module 100 and the second heat pump module 200 operate, and the heating system 1000 can provide a higher temperature rise.

[0038] For example, during the early and late cold seasons, the water supply temperature required by heat users is relatively low. Heat is provided solely by the low-temperature heat pump module, while the high-temperature heat pump module is not in operation. In this case, the heating system is simple, operating within a range with high compressor performance reliability, and the low-temperature heat pump module has a high heating coefficient. During severe cold seasons, when outdoor temperatures are low, the water supply temperature required by heat users is relatively high. Cascading operation of the low- and high-temperature heat pump modules can produce high-temperature hot water to meet the heating needs of heat users during these cold seasons.

[0039] The heating system of this application can implement different operating modes according to different external environments, allowing the compressor of the heating system to operate reliably in both low-temperature and high-temperature operating modes. Furthermore, the heating system can adapt to heating needs throughout the entire heating season, significantly improving the system's flexibility and reliability, and achieving intelligent control of the system through algorithms.

[0040] As an example, Figure 2As shown, the pipeline module 300 includes a main return pipe, a main water supply pipe, a first water pump 10, a second water pump 9, a first valve 1, a second valve 2, a third valve 3, a fourth valve 4, a fifth valve 5, a sixth valve 6, a seventh valve 7, an eighth valve 8 and a hot water tank 11. The first water pump 10 is arranged on the main return pipe, and the water outlet end of the first water pump 10 is connected to the first valve 1 and the second valve 2 respectively. The water outlet end of the first water pump 10 is connected to the water inlet end of the second water pump 9 through the first valve 1, the water outlet end of the first water pump 10 is connected to the first water inlet end of the second heat pump module 200 through the second valve 2, and the first water outlet end of the second heat pump module 200 is connected to the first water outlet end of the second heat pump module 200 through the third valve 3. It is connected to the water inlet of the hot water tank 11, the water outlet of the second water pump 9 is connected to the water inlet of the first heat pump module 100 through the fourth valve 4, the water outlet of the first heat pump module 100 is connected to the water inlet of the sixth valve 6 and the water inlet of the seventh valve 7 respectively through the fifth valve 5, the water outlet of the sixth valve 6 is also connected to the second water inlet of the second heat pump module 200, the second water outlet of the second heat pump module 200 is connected to the water inlet of the second water pump 9 through the eighth valve 8, the water outlet of the seventh valve 7 is connected to the water inlet of the hot water tank 11, and the water outlet of the hot water tank 11 is connected to the main water supply pipe, for providing the water after temperature treatment to the heat user 12 through the main water supply pipe.

[0041] Exemplarily, the piping module 300 includes a main return pipe, a main supply pipe, a first water pump 10, a second water pump 9, a first valve 1, a second valve 2, a third valve 3, a fourth valve 4, a fifth valve 5, a sixth valve 6, a seventh valve 7, an eighth valve 8, and a hot water tank 11. The first water pump 10 is disposed on the main return pipe and is used to pump user return water into the heating system. After passing through the first water pump 10, the user return water is divided into two streams. One stream passes through the second valve 2 and enters the second heat pump module 200 for heating. The other stream passes through the first valve 1 and flows into the water supply circuit connecting the first heat pump module 100 and the second heat pump module 200. It is then pumped into the water supply circuit connecting the first heat pump module 100 and the second heat pump module 200 through the second water pump 9. The return water at the outlet of the second water pump 9 passes through the fourth valve 4 and enters the first heat pump module 100 for heating. The water supply after the temperature treatment of the first heat pump module 100 is divided into two streams through the fifth valve 5. One stream flows into the hot water tank 11 through the seventh valve 7, and the other stream can flow into the second heat pump module 200 through the sixth valve 6. The water supply entering the second heat pump module 200 through the sixth valve 6 is then connected to the water inlet end of the second water pump 9 through the eighth valve 8.

[0042] It should be noted that the above-mentioned user return water flow path is the path when all valves are open. This application proposes two operating modes. Under different operating modes, the opening and closing conditions of the valves are different, and the user return water path is also different. The following is a detailed description of the user return water flow path in the cascade operating mode and the low-temperature operating mode.

[0043] As an example, in the cascade operation mode, the first valve 1 and the seventh valve 7 are controlled to be closed, the second valve 2, the third valve 3, the fourth valve 4, the fifth valve 5, the sixth valve 6, and the eighth valve 8 are controlled to be open, and the first water pump 10 and the second water pump 9 are controlled to operate, so that the user return water flows into the hot water tank 11 through the first water pump 10, the second valve 2, the second heat pump module 200, and the third valve 3 in sequence;

[0044] Among them, the water output of the second water pump 9 passes through the fourth valve 4, the first heat pump module 100, the fifth valve 5, the sixth valve 6, the second heat pump module 200 and the eighth valve 8 in sequence, and is used to transfer the heat energy of the first heat pump module 100 to the second heat pump module 200.

[0045] For example, in cascade operation mode, such as during the coldest winter months, when outdoor temperatures are low and user heating demand is high, requiring high system outlet water temperatures, a single-stage heat pump may struggle to operate safely and reliably. The system can then enter cascade operation. The centralized control module 13 closes the first valve 1 and the seventh valve 7, opens the second valve 2, the third valve 3, the fourth valve 4, the fifth valve 5, the sixth valve 6, and the eighth valve 8, and operates the first water pump 10 and the second water pump 9. At this point, user return water flows sequentially through the first water pump 10, the second valve 2, the second heat pump module 200, and the third valve 3 into the hot water tank 11, where the second heat pump module 200 heats the return water.

[0046] It should be noted that, in the cascade operation mode, although the first heat pump module 100 does not directly heat the user's return water, the first heat pump module 100 is still in operation, and the second water pump 9 is still running. The second water pump 9 circulates the water supply in the loop originally between the first heat pump module 100 and the second heat pump module 200 in the order of the fourth valve 4, the first heat pump module 100, the fifth valve 5, the sixth valve 6, the second heat pump module 200, and the eighth valve 8, so that the heat energy of the first heat pump module 100 is transferred to the second heat pump module 200. In this way, when the second heat pump module 200 heats the user's return water, the water temperature can be raised to a higher level to meet the user's heating needs during severe cold periods.

[0047] As an example, Figure 2 As shown, in the low-temperature operation mode, the second valve 2, the third valve 3, the sixth valve 6, and the eighth valve 8 are controlled to be closed, the first valve 1, the fourth valve 4, the fifth valve 5, and the seventh valve 7 are controlled to be open, and the first water pump 10 is controlled to be operated and the second water pump 9 is stopped, so that the user's return water flows into the hot water tank 11 through the first water pump 10, the first valve 1, the second water pump 9, the fourth valve 4, the first heat pump module 100, the fifth valve 5, and the seventh valve 7 in sequence.

[0048] For example, in low-temperature operation mode, such as during the early and late cold seasons of winter, when outdoor temperatures are high and user heating demand is low, the system outlet water temperature requirement is low. Single-stage heat pump operation can meet user needs, and the system enters low-temperature operation mode. Centralized control module 13 closes second valve 2, third valve 3, sixth valve 6, and eighth valve 8, opens first valve 1, fourth valve 4, fifth valve 5, and seventh valve 7, and operates first water pump 10, while shutting down second water pump 9. At this point, user return water flows sequentially through first water pump 10, first valve 1, second water pump 9, fourth valve 4, first heat pump module 100, fifth valve 5, and seventh valve 7 into hot water tank 11. The first heat pump module 100 independently heats the user return water. Second heat pump module 200 does not operate.

[0049] It should be noted that, although the second water pump 9 stops operating, the user's return water can still flow to the fourth valve 4 through the second water pump 9 .

[0050] In the present application, in the early cold period and the late cold period in winter, only the first heat pump module 100 is used to provide heat, which can save system resources and is more suitable for working conditions.

[0051] As an example, Figure 2 As shown, the first heat pump module 100 includes a first evaporator 100a, a first condenser 100e, a fan 100b, a first throttling device 100c and a first compressor 100d. The water inlet of the first evaporator 100a is connected to the water outlet of the first condenser 100e through the first compressor 100d, and the water inlet of the first condenser 100e is connected to the water outlet of the first evaporator 100a through the first throttling device 100c. The fan 100b is used to dissipate heat for the first evaporator 100a. The first heat pump module 100 is configured to absorb heat energy of water in the first evaporator 100a through the first evaporator 100a, and convert the heat energy into user return water flowing into the first condenser 100e through the first condenser 100e.

[0052] For example, the circuit formed by the first evaporator 100a, the first condenser 100e, the fan 100b, the first throttling device 100c and the first compressor 100d includes a refrigerant. When the first heat pump module 100 is running, the refrigerant circulates in sequence through the first evaporator 100a, the first throttling device 100c, the first condenser 100e, the first compressor 100d and the first evaporator 100a. The first evaporator 100a absorbs the heat energy of the water in the first evaporator 100a and converts the heat energy into user return water flowing into the first condenser 100e through the first condenser 100e.

[0053] It should be noted that the fan 100b is used to dissipate heat from the first evaporator 100a. In this example, the first evaporator 100a is air-cooled. However, the first evaporator 100a is not limited to air-cooled and may be other types. This application does not limit the type of heat pump module.

[0054] As an example, Figure 2 As shown, the second heat pump module 200 includes a second evaporator 200a, a second condenser 200b, a second throttling device 200c and a second compressor 200d. The water inlet end of the second evaporator 200a is connected to the water outlet end of the second condenser 200b through the second compressor 200d, and the water inlet end of the second condenser 200b is connected to the water outlet end of the second evaporator 200a through the second throttling device 200c. The second heat pump module 200 is configured to absorb the heat energy of the water in the second evaporator 200a through the second evaporator 200a, and convert the heat energy into user return water flowing into the second condenser 200b through the second condenser 200b.

[0055] For example, the second heat pump module 200 is similar to the first heat pump module 100, and the circuit formed by the second evaporator 200a, the second condenser 200b, the second throttling device 200c and the second compressor 200d includes a refrigerant. When the second heat pump module 200 is running, the refrigerant circulates in sequence along the path of the second evaporator 200a, the second throttling device 200c, the second condenser 200b, the second compressor 200d, and the second evaporator 200a. The second evaporator 200a absorbs the heat energy of the water in the second evaporator 200a and converts the heat energy into user return water flowing into the second condenser 200b through the second condenser 200b.

[0056] The heating system of the present application adjusts the operating mode of the heating system 1000 according to the applicability of user information and environmental information, thereby reducing system energy consumption and ensuring the performance of the compressor while meeting user needs.

[0057] As an example, Figure 3 As shown, the heating system 1000 also includes a ninth valve 14 and a tenth valve 15 . The water inlet of the sixth valve 6 is also connected to the second heat source inlet through the ninth valve 14 , and the water outlet of the second water pump 9 is also connected to the second heat source outlet through the tenth valve 15 .

[0058] For example, the present application may further provide a second heat source inlet between the fifth valve 5 and the sixth valve 6, and the second heat source enters the heating system circuit through the ninth valve 14. A second heat source outlet may also be provided between the second water pump 9 and the fourth valve 4, and the second heat source flows out of the heating system 1000 circuit through the tenth valve 15. The ninth valve 14 and the tenth valve 15 are used to control the second heat source inlet and the second heat source outlet. When a second heat source exists, the heating system can absorb the second heat source. For example, the fourth valve 4 and the fifth valve 5 are closed, and the first heat pump module 100 is closed. The heat source medium can enter the second heat pump module 200 through the second heat source inlet to release heat, and then discharge the medium from the second heat source outlet, so that the heating system can complete the flexible switching of the system heat source and help absorb different types of heat sources.

[0059] The control module 500 of the heating system 1000 is described in detail below.

[0060] As an example, the control module 500 is also used to: obtain user information and environmental information, and determine heating parameters and operating parameters of the heating system based on the user information and environmental information; determine the operating mode of the heating system based on the heating parameters and operating parameters.

[0061] Illustratively, the present application also proposes an optimized operation algorithm that reads user information and environmental information, and uses conventional or big data algorithms to determine the heating parameters and operating parameters of the heating system based on local user information and environmental information, and then adaptively determines the operating mode of the heating system based on the heating parameters and operating parameters.

[0062] For example, the user information may include the user's building type, the user's building age, the user's heating area, the user's heating terminal type, etc. The user's heating terminal type may include floor heating, fan coil units, radiators, and the like.

[0063] For example, the environmental information may include outdoor temperature, solar radiation intensity, wind speed, wind direction, historical operating heating, historical operating flow, and other information.

[0064] This application can determine the operating mode of the heating system based on user information and environmental information, which is more in line with user needs and more adapted to local conditions.

[0065] As an example, the heating parameters include the required water supply temperature, the operating parameters include the first maximum water outlet temperature in the low-temperature operation mode and the second maximum water outlet temperature in the cascade operation mode, and the control module 500 is also used to: when the required water supply temperature is greater than the first maximum water outlet temperature and less than or equal to the second maximum water outlet temperature, determine that the operating mode of the heating system is the cascade operation mode; when the required water supply temperature is less than or equal to the first maximum water outlet temperature, determine the operating mode of the heating system based on the first heating coefficient in the low-temperature operation mode and the second heating coefficient in the cascade operation mode.

[0066] Exemplarily, the heating parameters include the required water supply temperature, which can be denoted as Tg. The required water supply temperature Tg is calculated based on the collected user information and environmental information. It can be understood that the system's outlet water temperature reaches the required water supply temperature Tg to meet user needs.

[0067] Exemplarily, the operating parameters include a first maximum outlet water temperature in the low-temperature operating mode and a second maximum outlet water temperature in the cascade operating mode. The first maximum outlet water temperature in the low-temperature operating mode can be denoted as T1, and the second maximum outlet water temperature in the cascade operating mode can be denoted as T2. It will be understood that T1 and T2 are fixed values ​​when the first heat pump module and the second heat pump module are configured. The second maximum outlet water temperature T2 in the cascade operating mode is greater than the first maximum outlet water temperature T1 in the low-temperature operating mode.

[0068] Exemplarily, when the required water supply temperature Tg is greater than the first maximum water outlet temperature T1 and less than or equal to the second maximum water outlet temperature T2, it means that the unilateral heating in the low-temperature operation mode cannot meet the user's needs, and the cascade operation mode can meet the user's needs. At this time, the operation mode of the heating system is determined to be the cascade operation mode. When the required water supply temperature Tg is less than or equal to the first maximum water outlet temperature T1, it means that the unilateral heating in the low-temperature operation mode can meet the user's needs. At this time, the operation mode of the heating system can be directly determined to be the low-temperature operation mode. The present application also proposes a method for determining the operation mode. When the required water supply temperature Tg is less than or equal to the first maximum water outlet temperature T1, the operation mode of the heating system is determined based on the first heating coefficient in the low-temperature operation mode and the second heating coefficient in the cascade operation mode.

[0069] This application comprehensively considers user needs and the energy efficiency of the heating system to select the optimal operating mode, ensuring optimal energy efficiency while meeting user needs.

[0070] As an example, the control module is also used to: when the required water supply temperature is less than or equal to the first maximum water outlet temperature, if the first heating coefficient is greater than or equal to the second heating coefficient, determine that the operating mode of the heating system is a low-temperature operating mode; otherwise, determine that the operating mode of the heating system is a cascade operating mode.

[0071] For example, the Coefficient of Performance (COP) is the ratio of the heating capacity of a heating system to its input power. It is an important parameter for measuring the efficiency of a heat pump system. A higher COP value indicates that the heat pump system can provide more heat for the same input power. This application can also determine the operating mode based on the efficiency of the heating system.

[0072] The first heating coefficient in the low-temperature operating mode can be denoted as COP1, and the second heating coefficient in the cascade operating mode can be denoted as COP2. When the required water supply temperature Tg is less than or equal to the first maximum water outlet temperature T1, i.e., when the single-sided heating in the low-temperature operating mode can meet user needs, if the first heating coefficient COP1 is greater than or equal to the second heating coefficient COP2, the heating system's operating mode is determined to be the low-temperature operating mode. If the second heating coefficient COP2 is greater than the first heating coefficient COP1, this indicates that even though the single-sided heating in the low-temperature operating mode can meet user needs, the heating efficiency in the cascade operating mode is higher than that in the low-temperature operating mode, and the heating system's operating mode is determined to be the cascade operating mode.

[0073] Figure 4 This is a flow chart of a method for operating a heating system according to an embodiment of the present application.

[0074] like Figure 4 As shown, the heat user characteristics and local climate conditions are read, such as building type, age, heating area, heating terminal type (e.g., floor heating, fan coil units, and radiators), outdoor temperature, solar radiation intensity, wind speed, wind direction, and historical operating temperature and flow rates. Based on the obtained information and data, conventional or big data algorithms are used to determine information such as heat load Q, supply water temperature Tg, return water temperature Th, and water flow rate G. Furthermore, based on the obtained information and data, the first maximum outlet water temperature T1 (also known as the low-temperature outlet water temperature limit) and the corresponding heating capacity Q1 are determined for the low-temperature stage heating operation mode of the air-source water cascade heat pump under the corresponding conditions. The second maximum outlet water temperature T2 (also known as the cascade operation mode outlet water temperature limit) and the corresponding heating capacity Q2 are determined for the cascade heat pump under the corresponding conditions.

[0075] Then, compare the hot user demand water supply temperature Tg with the outlet water temperature limit T2 of the air source water cascade heat pump in the cascade operation mode. If T2 < Tg, it means that the heating system cannot meet the heating demand, and the equipment can be reselected (for example, reselect the heating method of the heat pump module, such as selecting a gas boiler, an electric boiler, or a better heat pump, etc.). If T2 > Tg, further compare the hot user demand water supply temperature Tg with the outlet water temperature limit T1 of the low-temperature stage of the air source water cascade heat pump. If T1 < Tg, it means that the heating operation mode of the low-temperature stage of the air source water cascade heat pump cannot meet the heating demand, and the cascade heating mode of the air source water cascade heat pump needs to be started. If T1 > Tg, further determine the heating coefficient COP1 in the heating operation mode of the low-temperature stage of the air source water cascade heat pump and the heating coefficient COP2 in the cascade operation mode of the air source water cascade heat pump according to the water supply temperature Tg. If COP1 < COP2, start the cascade heating mode of the air source water cascade heat pump. If COP1 > COP2, start the heating mode of the low-temperature stage of the air source water cascade heat pump.

[0076] This application also proposes a heating method.

[0077] As an example, as Figure 5 shown, the heating method is applied to the above heating system, including:

[0078] S501, obtain user information and environmental information, and determine the heating parameters and operation parameters of the heating system based on the user information and environmental information.

[0079] S502, determine the operation mode of the heating system based on the heating parameters and operation parameters, where the operation mode of the heating system includes a cascade operation mode and a low-temperature stage operation mode.

[0080] As an example, the heating parameters include the required water supply temperature, and the operation parameters include the first maximum outlet water temperature in the low-temperature stage operation mode and the second maximum outlet water temperature in the cascade operation mode. Determining the operation mode of the heating system based on the heating parameters and operation parameters includes:

[0081] When the required water supply temperature is greater than the first maximum outlet water temperature and less than or equal to the second maximum outlet water temperature, determine that the operation mode of the heating system is the cascade operation mode;

[0082] When the required water supply temperature is less than or equal to the first maximum outlet water temperature, determine the operation mode of the heating system according to the first heating coefficient in the low-temperature stage operation mode and the second heating coefficient in the cascade operation mode.

[0083] As an example, determining the operation mode of the heating system according to the first heating coefficient in the low-temperature stage operation mode and the second heating coefficient in the cascade operation mode includes:

[0084] If the first heating coefficient is greater than or equal to the second heating coefficient, the operation mode of the heating system is determined to be the low-temperature operation mode; otherwise, the operation mode of the heating system is determined to be the cascade operation mode.
