[0002] Promoting the full electrification of urban heating is an effective way to achieve clean and low-carbon heating. An air source heat pump absorbs heat from the air through an evaporator driven by electric energy and then releases the heat through a condenser. It has the characteristics of high efficiency, energy conservation, and environmental protection.

[0003] The heating coefficient of an air source heat pump is affected by the ambient temperature. The lower the ambient temperature, the lower the heating coefficient. Moreover, under low ambient temperature operation, the reliability of the compressor drops sharply, the failure rate increases, and it may even not work properly. In related technologies, a cascade heat pump can solve the problem that a heat pump cannot work in a low-temperature environment, but the cascade heating system has complex control and poor performance under variable working conditions.

Detailed implementation manners

[0024] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0025] Promoting the full electrification of urban heating is an effective way to achieve clean and low - carbon heating. Driven by electric energy, an air - source heat pump absorbs heat from the air through an evaporator and then releases the heat through a condenser. It has the characteristics of high efficiency, energy conservation, and environmental protection. The heating coefficient of an air - source heat pump is affected by the ambient temperature. The lower the ambient temperature, the lower the heating coefficient. Moreover, under low ambient temperature operation, the reliability of the compressor drops sharply, the failure rate rises, and it may even not work properly.

[0026] In some examples, using a cascade heat pump can solve the problem that a heat pump cannot work in a low - temperature environment. However, the control of a cascade heating system is complex and its performance under variable working conditions is poor. In the initial and final stages of heating, the ambient temperature is relatively high, resulting in deviation from the design working conditions and low efficiency of the heating system.

[0027] Based on this, the present application proposes an air - source water cascade heating system and an operation method, which can determine the required hot water flow rate and supply water temperature of the heating system according to outdoor climate conditions, and then determine the operation mode of the air - source water cascade heat pump, that is, determine whether it is heated by the low - temperature stage alone or by the cascade heating of the low - temperature stage and the high - temperature stage, with better adaptability and more in line with the actual working conditions.

[0028] Figure 1It is a schematic diagram of a heating system according to an embodiment of the present application.

[0029] As an example, as Figure 1 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 are configured to heat up the user return water; a pipeline module 300, the pipeline module 300 is connected to the first heat pump module 100, the second heat pump module 200, and the user terminal 400, the pipeline module 300 is configured to supply the user return water to the first heat pump module 100 and / or the second heat pump module 200, and supply the heated water to the user terminal 400; a control module 500, the control module 500 is connected to the pipeline module 300, the control module 500 is 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 the cascade operation mode, both the first heat pump module 100 and the second heat pump module 200 operate, and in the low-temperature operation mode, the first heat pump module 100 operates.

[0030] Exemplarily, the first heat pump module 100 and the second heat pump module 200 form a cascade heat pump heating system, both the first heat pump module 100 and the second heat pump module 200 are used to heat up the user return water, the pipeline module 300 is connected to the user terminal 400, recovers the user return water and supplies the user return water to the first heat pump module 100 and / or the second heat pump module 200. It can be understood that the user return water can be supplied to the first heat pump module 100, and the first heat pump module 100 heats up the user return water, or the user return water can be supplied to the second heat pump module 200, and the second heat pump module 200 heats up the user return water. The heated water is re-supplied to the user terminal 400 through the pipeline module 300, and thus the cycle heating is carried out. The pipeline module 300 is connected to the control module 500, and the control module 500 can be a host computer to centrally control the devices in the heating system 1000. For example, it can control the opening and closing of the valves in the pipeline module 300.

[0031] Exemplarily, the present application uses an algorithm to implement a heat pump control system that comprehensively considers the characteristics of heat users and local climate conditions. The control module 500 obtains user information and environmental information. The user information includes, for example, the type of user building, the age of the user building, etc., and the environmental information includes, for example, environmental temperature, environmental humidity, etc. The present application determines the operating mode of the heating system 1000 according to the user information and environmental information by optimizing the control algorithm. The operating modes of the heating system 1000 include a cascaded operating mode and a low-temperature stage operating mode. In the cascaded operating mode, both the first heat pump module 100 and the second heat pump module 200 operate. In the low-temperature stage operating mode, the first heat pump module 100 operates. It can be understood that the first heat pump module 100 is a low-temperature stage heat pump module, and the second heat pump module 200 is a high-temperature stage heat pump module. In the cascaded 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 heating temperature.

[0032] For example, in the initial cold and final cold periods of heating, the required water supply temperature of heat users is relatively low. The heating is provided solely by the low-temperature stage heat pump module, and the high-temperature stage heat pump module does not operate. At this time, the heating system is simple, the system operates in a range with relatively high compressor performance reliability, and the low-temperature stage heating coefficient is relatively high. In the severe cold period, the outdoor temperature is relatively low, and the required water supply temperature of heat users is relatively high. The low-temperature stage and the high-temperature stage operate in cascade to produce high-temperature hot water to meet the heating requirements of heat users in the severe cold period.

[0033] The heating system of the present application can implement different operating modes according to different external environments, enabling the compressors in both the low-temperature stage operating mode and the high-temperature stage operating mode of the heating system to operate reliably. Moreover, the heating system can adapt to the heating requirements throughout the heating season, greatly improving the flexibility and reliability of the system, and realizing the intelligent control of the system through an algorithm.

[0034] As an example, such as Figure 2As shown in the figure, the pipeline module 300 includes a main return water 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 water pipe. The water outlet end of the first water pump 10 is respectively connected to the first valve 1 and the second valve 2. 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. The first water outlet end of the second heat pump module 200 is connected to the water inlet end of the hot water tank 11 through the third valve 3. The water outlet end of the second water pump 9 is connected to the water inlet end of the first heat pump module 100 through the fourth valve 4. The water outlet end of the first heat pump module 100 is respectively connected to the water inlet end of the sixth valve 6 and the water inlet end of the seventh valve 7 through the fifth valve 5. The water outlet end of the sixth valve 6 is further connected to the second water inlet end of the second heat pump module 200. The second water outlet end of the second heat pump module 200 is connected to the water inlet end of the second water pump 9 through the eighth valve 8. The water outlet end of the seventh valve 7 is connected to the water inlet end of the hot water tank 11. The water outlet end of the hot water tank 11 is connected to the main water supply pipe, and is used to supply the heated water to the heat user 12 through the main water supply pipe.

[0035] Exemplarily, the pipeline module 300 includes a main return water 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 water pipeline and is used to pump the user return water into the heating system. After passing through the first water pump 10, the user return water is divided into two branches. One branch enters the second heat pump module 200 through the second valve 2 for temperature raising treatment, and the other branch flows into the water supply loop connecting the first heat pump module 100 and the second heat pump module 200 through the first valve 1 and is pumped into the water supply loop 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 water outlet end of the second water pump 9 enters the first heat pump module 100 through the fourth valve 4 for temperature raising treatment. The water supply after the temperature raising treatment by the first heat pump module 100 is divided into two branches through the fifth valve 5. One branch flows into the hot water tank 11 through the seventh valve 7, and the other branch 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 connected to the water inlet end of the second water pump 9 through the eighth valve 8 again.

[0036] It should be noted that the above-mentioned path of the user return water flow is the path when all valves are open. The present application proposes two operation modes. Under different operation modes, the opening and closing conditions of the valves are different, and the path of the user return water is also different. The path of the user return water flow under the cascade operation mode and the low-temperature stage operation mode will be described in detail below.

[0037] As an example, in the cascade operation mode, control the first valve 1 and the seventh valve 7 to close, control 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 to open, and control the first water pump 10 and the second water pump 9 to operate, so that the user's return water sequentially passes through the first water pump 10, the second valve 2, the second heat pump module 200, and the third valve 3 and flows into the hot water tank 11. Among them, the water output of the second water pump 9 sequentially 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, and is used to transfer the heat energy of the first heat pump module 100 to the second heat pump module 200.

[0038] Exemplarily, in the cascade operation mode, for example, during the severe cold period in winter, the outdoor temperature is relatively low, the user's heating demand is relatively large, the requirement for the system's water output temperature is relatively high, and it is difficult for a single-stage heat pump to operate safely and reliably. The system can turn on the cascade operation mode. The centralized control module 13 controls the first valve 1 and the seventh valve 7 to close, controls 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 to open, and controls the first water pump 10 and the second water pump 9 to operate. At this time, the user's return water sequentially passes through the first water pump 10, the second valve 2, the second heat pump module 200, and the third valve 3 and flows into the hot water tank 11, and the second heat pump module 200 performs a temperature increase process on the user's return water.

[0039] It should be noted that in the cascade operation mode, although the first heat pump module 100 does not directly perform a temperature increase process on the user's return water, the first heat pump module 100 is still in an operating state, and the second water pump 9 still operates. 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 performs a temperature increase process on the user's return water, the water temperature can be increased higher to meet the user's heating demand during the severe cold period.

[0040] As an example, as Figure 2 shown, in the low-temperature stage operation mode, control the second valve 2, the third valve 3, the sixth valve 6, and the eighth valve 8 to close, control the first valve 1, the fourth valve 4, the fifth valve 5, and the seventh valve 7 to open, and control the first water pump 10 to operate, and the second water pump 9 stops operating, so that the user's return water sequentially passes 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 and flows into the hot water tank 11.

[0041] Exemplarily, in the low-temperature stage operation mode, for example, in the early cold period and the late cold period of winter, the outdoor temperature is relatively high, the user's heating demand is small, the requirement for the system's outlet water temperature is low, and the single-stage operation of the heat pump can meet the user's needs, so the system turns on the low-temperature stage operation mode. The centralized control module 13 controls the second valve 2, the third valve 3, the sixth valve 6, and the eighth valve 8 to close, controls the first valve 1, the fourth valve 4, the fifth valve 5, and the seventh valve 7 to open, and controls the first water pump 10 to operate while the second water pump 9 stops operating. At this time, the user's return water flows into the hot water tank 11 successively 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, and the first heat pump module 100 alone heats up the user's return water. The second heat pump module 200 does not operate.

[0042] It should be noted that although the second water pump 9 stops operating, the user's return water can still flow through the second water pump 9 to the fourth valve 4.

[0043] In the early cold period and the late cold period of winter in this application, only the first heat pump module 100 provides heating, which can save system resources and is more suitable for the working conditions.

[0044] As an example, as Figure 2 shown, the first heat pump module 100 includes a first evaporator 100a, a first condenser 100e, a blower 100b, a first throttling device 100c, and a first compressor 100d. The water inlet end of the first evaporator 100a is connected to the water outlet end of the first condenser 100e through the first compressor 100d. The water inlet end of the first condenser 100e is connected to the water outlet end of the first evaporator 100a through the first throttling device 100c. The blower 100b is used to dissipate heat from the first evaporator 100a. The first heat pump module 100 is configured to absorb the heat energy of the water in the first evaporator 100a through the first evaporator 100a and convert the heat energy to the user's return water flowing into the first condenser 100e through the first condenser 100e.

[0045] Exemplarily, a refrigerant is included in the loop formed by the first evaporator 100a, the first condenser 100e, the blower 100b, the first throttling device 100c, and the first compressor 100d. When the first heat pump module 100 operates, the refrigerant circulates successively along the path of 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 to the user's return water flowing into the first condenser 100e through the first condenser 100e.

[0046] 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 of the air-cooled type. Of course, the first evaporator 100a is not limited to the air-cooled type, and it can also be of other types. The form of the heat pump module in this application is not restricted.

[0047] As an example, as Figure 2 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. 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 to the user return water flowing into the second condenser 200b through the second condenser 200b.

[0048] Exemplarily, the second heat pump module 200 is the same as the first heat pump module 100. A refrigerant is included in the loop formed by the second evaporator 200a, the second condenser 200b, the second throttling device 200c, and the second compressor 200d. When the second heat pump module 200 operates, the refrigerant circulates in 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 in sequence. The second evaporator 200a absorbs the heat energy of the water in the second evaporator 200a, and converts the heat energy to the user return water flowing into the second condenser 200b through the second condenser 200b.

[0049] The heating system of this application adaptively adjusts the operating mode of the heating system 1000 according to user information and environmental information, reduces the system energy consumption on the premise of meeting user requirements, and ensures the performance of the compressor.

[0050] As an example, as Figure 3 shown, the heating system 1000 further includes a ninth valve 14 and a tenth valve 15. The water inlet end of the sixth valve 6 is also connected to the second heat source inlet through the ninth valve 14. The water outlet end of the second water pump 9 is also connected to the second heat source outlet through the tenth valve 15.

[0051] Exemplarily, the present application may further provide a second heat source inlet between the fifth valve 5 and the sixth valve 6. The second heat source enters the heating system loop 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. The second heat source flows out of the heating system 1000 loop 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 there is a second heat source, the heating system can consume the second heat source. For example, when the fourth valve 4 and the fifth valve 5 are closed and the first heat pump module 100 is turned off, the heat source medium can enter the second heat pump module 200 through the second heat source inlet, release heat, and then discharge the medium from the second heat source outlet, enabling the heating system to flexibly switch the system heat source and help consume different types of heat sources.

[0052] The control module 500 of the heating system 1000 will be described in detail below.

[0053] As an example, the control module 500 is further configured to: obtain user information and environmental information, and determine the 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.

[0054] Exemplarily, the present application also proposes an optimized operation algorithm that reads user information and environmental information, determines the heating parameters and operating parameters of the heating system using conventional or big data algorithms according to the 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.

[0055] Exemplarily, the user information may include user building type, user building age, user heating area, user heating terminal type, etc. The user heating terminal type includes, for example, types such as floor heating, fan coil units, and radiators.

[0056] Exemplarily, the environmental information may include information such as outdoor temperature, solar irradiance intensity, wind speed, wind direction, historical operating supply temperature, and historical operating flow rate.

[0057] The present application can determine the operating mode of the heating system according to user information and environmental information, which better meets user needs and is more adaptable to local conditions.

[0058] As an example, the heating parameters include the required water supply temperature, and the operating parameters include the first maximum outlet water temperature in the low-temperature stage operating mode and the second maximum outlet water temperature in the cascade operating mode. The control module 500 is further configured to: 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 operating mode of the heating system is the cascade operating mode; when the required water supply temperature is less than or equal to the first maximum outlet water temperature, determine the operating mode of the heating system according to the first heating coefficient in the low-temperature stage operating mode and the second heating coefficient in the cascade operating mode.

[0059] 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 outlet water temperature of the system needs to reach the required water supply temperature Tg to meet the user's needs.

[0060] Exemplarily, the operating parameters include the first maximum outlet water temperature in the low-temperature stage operating mode and the second maximum outlet water temperature in the cascade operating mode. The first maximum outlet water temperature in the low-temperature stage 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 can be understood that when the devices of the first heat pump module and the second heat pump module are determined, T1 and T2 are fixed values. 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 stage operating mode.

[0061] Exemplarily, when the required water supply temperature Tg is greater than the first maximum outlet water temperature T1 and less than or equal to the second maximum outlet water temperature T2, it indicates that the single-sided heating in the low-temperature stage operating mode cannot meet the user's needs, and the cascade operating mode can meet the user's needs. At this time, determine that the operating mode of the heating system is the cascade operating mode. When the required water supply temperature Tg is less than or equal to the first maximum outlet water temperature T1, it indicates that the single-sided heating in the low-temperature stage operating mode can meet the user's needs. At this time, the operating mode of the heating system can be directly determined as the low-temperature stage operating mode. The present application also proposes a method for determining the operating mode. When the required water supply temperature Tg is less than or equal to the first maximum outlet water temperature T1, determine the operating mode of the heating system according to the first heating coefficient in the low-temperature stage operating mode and the second heating coefficient in the cascade operating mode.

[0062] The present application comprehensively considers the user's needs and the energy efficiency of the heating system to select the optimal operating mode, ensuring the optimal energy efficiency while meeting the user's needs.

[0063] As an example, the control module is further configured to: when the required water supply temperature is less than or equal to the first maximum outlet water temperature, if the first heating coefficient is greater than or equal to the second heating coefficient, determine that the operation mode of the heating system is the low-temperature stage operation mode; otherwise, determine that the operation mode of the heating system is the cascade operation mode.

[0064] Exemplarily, the coefficient of performance (COP) is the ratio of the heat output to the input power in the heating system, and is an important parameter for measuring the efficiency of the heat pump system. The higher the COP value, the more heat can be provided by the heat pump system under the same input power. The operation mode of the present application can also be determined according to the efficiency of the heating system.

[0065] Let the first heating coefficient in the low-temperature stage operation mode be COP1, and the second heating coefficient in the cascade operation mode be COP2. When the required water supply temperature Tg is less than or equal to the first maximum outlet water temperature T1, that is, the single-side heating in the low-temperature stage operation mode can meet the user's demand at this time. If the first heating coefficient COP1 is greater than or equal to the second heating coefficient COP2, determine that the operation mode of the heating system is the low-temperature stage operation mode. If the second heating coefficient COP2 is greater than the first heating coefficient COP1, it means that even though the single-side heating in the low-temperature stage operation mode can meet the user's demand, the heating efficiency in the cascade operation mode is higher than that in the low-temperature stage operation mode. At this time, determine that the operation mode of the heating system is the cascade operation mode.

[0066] Figure 4 It is a flowchart of the operation method of the heating system according to an embodiment of the present application.

[0067] As Figure 4 shown, read the characteristics of heat users and local climate conditions, for example, building type, age, heating area, type of heating terminal (such as floor heating, fan coil, and radiator), outdoor temperature, solar radiation intensity, wind speed, wind direction, and historical operation water supply temperature, flow rate, and other relevant information. According to the obtained information and data, use conventional or big data algorithms to determine information such as the heat load Q, water supply temperature Tg, return water temperature Th, and water flow rate G. And according to the obtained information and data, determine the first maximum outlet water temperature T1 (also called the low-temperature stage outlet water temperature limit) and the corresponding heat output Q1 in the low-temperature stage heating operation mode of the air-source water-cascade heat pump under corresponding conditions, and determine the second maximum outlet water temperature T2 (also called the cascade operation mode outlet water temperature limit) and the heat output Q2 when the cascade heat pump operates in cascade heating under corresponding conditions.

[0068] Then, judge the magnitude relationship between the water supply temperature Tg required by the heat user and 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 judge the magnitude relationship between the water supply temperature Tg required by the heat user and 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.

[0071] 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.

[0072] 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: 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; 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.

[0073] 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: If the first heat supply coefficient is greater than or equal to the second heat supply coefficient, determine that the operation mode of the heat supply system is the low-temperature operation mode; otherwise, determine that the operation mode of the heat supply system is the cascade operation mode.
