Description

Technical Field

[0001] This application relates to the field of water source heating technology, and in particular to a composite water source heating method, electronic equipment, readable storage medium, and computer program product. Background Technology

[0002] In homes using municipal heating, users often install water source heat pumps as auxiliary heating devices to improve heating efficiency, connecting them to the municipal heating pipeline. A water source heat pump is a device that utilizes low-grade heat energy, such as solar or geothermal energy absorbed by water, and upgrades it into high-grade heat energy suitable for building heating through a compression cycle.

[0003] For example, Chinese patent CN112283976B discloses a water source heat pump system, including a water source heat pump unit. The water source heat pump unit includes an evaporator, a condenser, a water distributor, a connector, and multiple valves. Each valve is connected to the evaporator, condenser, water distributor, and connector, and heating and cooling are achieved through valve control.

[0004] However, due to the instability of municipal heating systems, the supply water temperature often exceeds or falls below the standard heating water temperature, causing a series of operational problems for these composite heating systems. When municipal heating experiences an "oversupply," meaning the supply water temperature is abnormally high, the evaporation temperature of the water source heat pump will rise accordingly, affecting the unit's heat exchange efficiency and, in severe cases, even triggering a protective shutdown. Conversely, when the municipal heating water temperature is too low, relying solely on municipal heating cannot meet the users' indoor comfort needs.

[0005] Therefore, in such a combined heating system, how to effectively deal with the fluctuations in municipal heating water temperature, prevent the water source heat pump from malfunctioning due to excessively high water temperature, and avoid insufficient heating due to excessively low water temperature has become an urgent technical problem to be solved.

[0006] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0020] Optionally, the steps of adjusting the state of the inlet valve group and / or drain valve group according to the heating mode, and controlling the start and stop of the water source heat pump unit, include:

[0021] When the composite water source heating system is in direct heating mode, the inlet valve group is controlled to switch to the bypass position, the drain valve group is controlled to switch to the drain position, and the water source heat pump unit is controlled to stop.

[0022] When the composite water source heating system is in secondary heating mode, the inlet valve group is controlled to switch to the heat pump position, the drain valve group is controlled to switch to the shut-off position, and the water source heat pump unit is started.

[0023] Optionally, the inlet valve group includes a first solenoid valve and a second solenoid valve, and the drain valve group includes a third solenoid valve; the steps of adjusting the state of the inlet valve group and / or the drain valve group according to the heating mode, and controlling the start and stop of the water source heat pump unit include:

[0024] Based on the direct heating mode, a first valve adjustment command is output, which includes a first solenoid valve closing signal, a second solenoid valve opening signal, and a third solenoid valve opening signal.

[0025] Based on the secondary heating mode, a second valve adjustment command is output, which includes a first solenoid valve opening signal, a second solenoid valve closing signal, and a third solenoid valve closing signal.

[0026] Optionally, the step of outputting a second valve adjustment command based on the secondary heating mode, wherein the second valve adjustment command includes a first solenoid valve opening signal, a second solenoid valve closing signal, and a third solenoid valve closing signal, includes:

[0041] By acquiring the real-time water temperature of the municipal heating water supply pipes, the heating condition of the municipal heating water supply pipes is determined. When the water temperature is too high, the system automatically switches to bypass direct supply mode to protect the water source heat pump unit from high-temperature damage. Simultaneously, when the water temperature is too low, the water source heat pump unit is activated for secondary heating to compensate for the heating shortfall. By adjusting the heating mode based on the heating condition, the status of the inlet valve group and / or drain valve group is adjusted, and the start and stop of the water source heat pump unit are controlled. This linkage control of valve opening and unit start / stop ensures that the water source heat pump unit always operates under safe conditions and guarantees stable and comfortable terminal heating effects.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0050] It should be noted that in the description of this application and the appended claims, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0052] It should be noted that the executing entity in this embodiment can be an electronic device with data processing, network communication and program running functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of realizing the above functions.

[0053] Reference Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the composite water source heating method of this application. In this embodiment, the composite water source heating method is applied to a composite water source heating system, which includes a municipal heating water supply pipe, a water source heat pump unit, an inlet valve group, and a drain valve group; the composite water source heating method includes steps S100 to S400:

[0054] Step S100: Monitor the real-time water temperature of the municipal heating water supply pipe.

[0055] It should be noted that in a combined water source heating system, the water source heat pump unit is connected in series with the municipal heating water supply pipe; the inlet valve assembly connects one end to the municipal heating water supply pipe, one end to the water source heat pump unit, and the other end to the terminal heating system in the user's home. The terminal heating system includes, but is not limited to, fan coil units, radiator fins, wall or floor heating coils, etc. The inlet valve assembly controls the flow of water from the municipal heating water supply pipe into the water source heat pump unit and the terminal heating system. The drain valve assembly is connected to the water source heat pump unit and controls the direction of the return water from the terminal heating system.

[0056] In this embodiment, a temperature sensor is installed at the main inlet of the municipal heating water supply pipe into the user's home heating system, before the inlet valve group, to continuously and in real-time measure the temperature of the water flowing into the composite water source heating system.

[0057] For example, suppose the temperature sensor is a resistance temperature sensor, which is fixed inside the municipal heating water supply pipe and in direct contact with the flowing hot water to accurately measure the water temperature. When the municipal heating system starts pressurizing and supplying heat, the resistance temperature sensor detects the change in water temperature inside the pipe and continuously acquires the real-time water temperature to establish a real-time temperature curve.

[0058] Step S200: Determine the heating status of the municipal heating water supply pipe based on the real-time water temperature.

[0059] It should be noted that the heating conditions of municipal heating water supply pipes can include overheating, underheating, and normal heating. Overheating means that the water temperature in the municipal heating water supply pipes is too high, underheating means that the water temperature in the municipal heating water supply pipes is too low, and normal heating means that the water temperature in the municipal heating water supply pipes is within the temperature range that the water source heat pump unit can withstand.

[0060] In this embodiment, the real-time water temperature can be compared with a preset temperature threshold range to make a qualitative judgment on the current heating condition of the municipal heating water supply pipe. By determining the heating condition through real-time water temperature, the continuous physical signal (real-time water temperature) is transformed into a discrete and clear status label, and water temperature fluctuations are transformed into clear heating conditions, ensuring that subsequent adjustment and control actions have a clear basis.

[0061] In one feasible implementation, step S200 includes determining that if the real-time water temperature is higher than a preset high-temperature threshold, the heating condition is overheating; if the real-time water temperature is lower than a preset low-temperature threshold, the heating condition is underheating. Wherein, the high-temperature threshold is greater than or equal to the low-temperature threshold.

[0062] In this embodiment, if the real-time water temperature is higher than the preset high-temperature threshold, it indicates that the municipal water supply temperature is already too high, sufficient to directly meet or even exceed the heating needs of the end user. Allowing the water to directly enter the water source heat pump would result in excessively high evaporation temperatures, reduced efficiency, and potential malfunctions. If the real-time water temperature is lower than the preset low-temperature threshold, it indicates that the municipal water supply temperature is too low, and its own heat alone is insufficient to achieve a comfortable indoor temperature. In this case, the water source heat pump needs to be activated to reheat the water flow.

[0063] Optionally, the high-temperature threshold being greater than or equal to the low-temperature threshold can be selected according to the needs of the actual application scenario, and this embodiment does not impose specific restrictions on this. For example, in application scenarios where it is necessary to avoid frequent changes in the heating mode of the composite water source heating system around a certain temperature value, the high-temperature threshold can be set to be greater than the low-temperature threshold. In application scenarios where frequent changes in the heating mode of the composite water source heating system around a certain temperature value are not considered, the high-temperature threshold can be set to be equal to the low-temperature threshold. For example, a high-temperature threshold of 75 degrees Celsius can be selected, and a low-temperature threshold of 20 degrees Celsius can be selected; or, a high-temperature threshold equal to a low-temperature threshold equal to 50 degrees Celsius can be selected.

[0064] The purpose of this approach is to provide a unique and reliable criterion for the system to switch between bypass mode (direct heating mode) to protect the heat pump and heating mode (secondary heating mode) to enhance heating, by setting clear and unambiguous temperature thresholds. Furthermore, by determining operating conditions, the most economical operating strategy can be selected under different circumstances: saving energy consumption of the heat pump when heating is excessive; and actively supplementing heat when heating is insufficient, ensuring indoor warmth and comfort, thus resolving user experience issues caused by water temperature fluctuations.

[0065] Step S300: Adjust the heating mode based on the heating conditions.

[0066] It should be noted that heating modes include direct heating and secondary heating. In direct heating mode, municipal heating water flows directly into the terminal heating system, i.e., bypass direct supply mode. In this mode, the water source heat pump unit is bypassed to protect it from high-temperature damage. In secondary heating mode, municipal heating water first enters the water source heat pump unit for secondary heating before flowing into the terminal heating system, i.e., heat pump assisted heating mode. In this mode, the water source heat pump unit is activated to reheat the low-temperature incoming water to meet heating needs.

[0067] In this embodiment, by adjusting the heating mode according to the heating conditions, it is determined whether the water source heat pump unit participates in heating at this stage, and whether the current priority is to protect the heat pump or to ensure heating.

[0068] Optionally, step S300 includes adjusting the heating mode to a direct heating mode when the municipal heating water supply pipe provides excessive heating; and adjusting the heating mode to a secondary heating mode when the municipal heating water supply pipe provides insufficient heating.

[0069] In this embodiment, when it is determined that the current municipal heating is in an overheating condition, since the municipal water supply itself has sufficient or even excessive heat, the heating mode is adjusted to direct heating mode. In direct heating mode, water supply to the water source heat pump unit is stopped, and the water source heat pump unit stops working.

[0070] When it is determined that the municipal heating system is currently experiencing insufficient heating, the heating mode is adjusted to a secondary heating mode because the municipal heating water is not hot enough. In the secondary heating mode, the low-temperature water first flows through the water source heat pump unit to increase its heat, and then becomes high-temperature water before being sent to the terminal heating system.

[0071] The purpose of this is to prevent the water source heat pump unit from malfunctioning due to excessively high water temperatures through direct heating. In other words, by using a bypass mode under high-temperature conditions, the water source heat pump is prevented from operating beyond its capacity, thus protecting core components such as the compressor and extending the overall lifespan of the unit. Furthermore, the secondary heating mode prevents situations where insufficient heating is required due to excessively low water temperatures.

[0072] Step S400: Adjust the state of the inlet valve group and / or drain valve group according to the heating mode, and control the start and stop of the water source heat pump unit.

[0073] In this embodiment, if the heating mode is direct heating, the inlet valve group is controlled to close the inlet valve leading to the water source heat pump unit, open the bypass pipeline valve, and the drain valve group is controlled to open the drain valve, while simultaneously stopping the water source heat pump to achieve bypass direct heating. If the heating mode is secondary heating, the inlet valve group is controlled to open the inlet valve leading to the water source heat pump unit, the drain valve group is controlled to close the drain valve, and simultaneously starting the water source heat pump. By interlocking the control valves and the water source heat pump unit, the heat source is isolated to protect the equipment at high temperatures, and the heat pump is introduced to raise the water supply temperature at low temperatures, thereby avoiding the impact of fluctuations in municipal water temperature.

[0074] In one feasible implementation, step S400 may include steps S410 to S420:

[0075] Step S410: When the composite water source heating system is in direct heating mode, control the inlet valve group to switch to the bypass position, control the drain valve group to switch to the drain position, and control the water source heat pump unit to stop.

[0076] Step S420: When the composite water source heating system is in secondary heating mode, control the inlet valve group to switch to the heat pump position, control the drain valve group to switch to the shut-off position, and start the water source heat pump unit.

[0077] In this embodiment, the composite water source heating system also includes a terminal heating inlet pipe, a terminal heating outlet pipe, and a municipal heating return pipe.

[0078] According to the control commands corresponding to the direct heating mode, the inlet valve group is switched to the bypass position to connect the municipal heating water supply pipe and the terminal heating inlet pipe, allowing municipal heating water to directly enter the terminal heating system for heating. The drain valve group is switched to the drain position to connect the municipal heating return pipe and the terminal heating outlet pipe, allowing the return water from the terminal heating system to be discharged back to the municipal heating return pipe. This allows municipal heating water to directly provide heat to the terminal heating system, preventing damage to the water source heat pump unit due to high temperatures. Simultaneously, the water source heat pump unit is shut down, ensuring complete protection under high-temperature conditions and saving energy. In other words, by completely isolating and shutting down the water source heat pump unit from the high-temperature water circuit, efficiency reduction, component wear, or shutdown due to excessively high evaporation temperatures is fundamentally avoided. Furthermore, even when the heat pump is not operating, the indoor temperature can be maintained using heat from the municipal heating system.

[0079] According to the control commands corresponding to the secondary heating mode, the inlet valve group is switched to the heat pump position to connect the municipal heating water supply pipe and the water source heat pump unit, ensuring that the low-temperature water flows through the water source heat pump unit first. The drain valve group is switched to the shut-off position to cut off the connection between the municipal heating return pipe and the terminal heating outlet pipe, allowing the return water from the terminal heating system to enter the water source heat pump unit. Simultaneously, the compressor and water pump of the water source heat pump unit are started to raise the low-temperature municipal heating water to a higher temperature, enabling the water source heat pump unit to provide heat to the terminal heating system. By starting the water source heat pump unit to reheat the low-temperature water, the water temperature delivered to the terminal heating system is ensured to be high enough to meet the user's heating needs. Furthermore, by disconnecting the terminal heating outlet pipe from the municipal heating return pipe, an independent circulation is formed between the water source heat pump unit and the terminal heating system within the household, avoiding energy loss and ensuring that all heat is used for the user's own heating.

[0080] For example, please refer to Figure 2 Assume the inlet valve group includes a first solenoid valve and a second solenoid valve, and the drain valve group includes a third solenoid valve. The first solenoid valve is connected at one end to the municipal heating water supply pipe and at the other end to the water source heat pump unit; the second solenoid valve is connected at one end to the municipal heating water supply pipe and at the other end to the terminal heating inlet pipe; the third solenoid valve is connected at one end to the municipal heating return pipe and at the other end to the terminal heating outlet pipe. Step S400 may include, based on the direct heating mode, outputting a first valve adjustment command, which includes a first solenoid valve closing signal, a second solenoid valve opening signal, and a third solenoid valve opening signal; and based on the secondary heating mode, outputting a second valve adjustment command, which includes a first solenoid valve opening signal, a second solenoid valve closing signal, and a third solenoid valve closing signal.

[0081] For example, a composite water source heating system also includes a Y-shaped filter, a first ball valve, a second ball valve, a third ball valve, and a fourth ball valve; a terminal heating system includes radiators or heating coils, fan coil units, underfloor heating coils or wall coils; and a water source heat pump unit includes...

[0082] The Y-shaped filter is connected between the municipal heating water supply pipe and the first solenoid valve to filter impurities in the municipal heating water, preventing them from entering the water source heat pump unit and the terminal heating system, thus affecting their service life. The first, second, third, and fourth ball valves are in the normally open state.

[0083] A high-temperature threshold of 65 degrees Celsius is selected. Assume that the municipal heating supply water temperature abnormally rises to 80 degrees Celsius due to solar energy gain. The composite water source heating system enters direct heating mode. Based on the closing signal of the first solenoid valve and the opening signal of the second solenoid valve in the first valve adjustment command, the inlet valve group adjusts the first solenoid valve to be closed and the second solenoid valve to be open, thus placing the inlet valve group in the bypass position. The drain valve group adjusts the third solenoid valve to be open based on the opening signal of the third solenoid valve in the first valve adjustment command. At this time, the water in the municipal heating supply pipe flows through the Y-shaped filter, then through the second solenoid valve, into the terminal heating inlet pipe, and then through the fourth ball valve to enter the terminal heating system for heat dissipation. Then, the water after being cooled by the terminal heating system enters the terminal heating outlet pipe through the third ball valve, and then flows through the third solenoid valve to enter the municipal heating return pipe.

[0084] Assuming a low-temperature threshold of 30 degrees Celsius, and assuming that on a frigid night, the municipal water supply temperature drops to 20 degrees Celsius, which is insufficient to meet the needs of the terminal heating system, the composite water source heating system enters secondary heating mode. Based on the opening and closing signals of the first and second solenoid valves in the second valve adjustment command, the inlet valve group adjusts the first solenoid valve to the open state and the second solenoid valve to the closed state, placing the inlet valve group in the heat pump position. The drain valve group adjusts the third solenoid valve to the closed state based on the closing signal of the third solenoid valve in the first valve adjustment command. At this time, water from the municipal heating supply pipe flows through the Y-shaped filter, then through the first solenoid valve into the water source heat pump unit for heating; then, the water heated by the water source heat pump unit flows into the terminal heating inlet pipe and enters the terminal heating system for heat dissipation through the fourth ball valve; finally, the water cooled by the terminal heating system enters the terminal heating outlet pipe through the third ball valve and flows back to the water source heat pump unit.

[0085] Furthermore, to ensure that the heating effect of the terminal heating system does not fluctuate excessively when switching heating modes in the composite water source heating system, the step of outputting a second valve adjustment command based on the secondary heating mode may include: obtaining the secondary heating level corresponding to the real-time water temperature; determining the pulse opening degree of the first, second, and third solenoid valves based on the secondary heating level; and generating the second valve adjustment command according to the pulse opening degree of the first, second, and third solenoid valves.

[0086] Specifically, when the secondary heating level is Level 1, the pulse opening degree of the first solenoid valve is set to 30%, the pulse opening degree of the second solenoid valve to 70%, and the pulse opening degree of the third solenoid valve to 0%. When the secondary heating level is Level 2, the pulse opening degree of the first solenoid valve is set to 60%, the pulse opening degree of the second solenoid valve to 40%, and the pulse opening degree of the third solenoid valve to 0%. When the secondary heating level is Level 3, the pulse opening degree of the first solenoid valve is set to 100%, the pulse opening degree of the second solenoid valve to 0%, and the pulse opening degree of the third solenoid valve to 0%.

[0087] In the technical solution provided in this embodiment, after obtaining the real-time water temperature of the municipal heating water supply pipe, the heating condition of the municipal heating water supply pipe is determined. Therefore, when the water temperature is too high, it automatically switches to a bypass direct supply mode to protect the water source heat pump unit from high-temperature damage. Simultaneously, when the water temperature is too low, the water source heat pump unit is started for secondary heating to compensate for the heating gap. By adjusting the heating mode based on the heating condition, the state of the inlet valve group and / or drain valve group is adjusted, and the start and stop of the water source heat pump unit are controlled. This linkage control of valve opening and unit start and stop ensures that the water source heat pump unit always operates under safe conditions and guarantees the stability and comfort of the terminal heating effect.

[0088] Based on the first embodiment of this application, a second embodiment of the composite water source heating method of this application is proposed. In this embodiment, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The composite water source heating method further includes steps S500 to S600:

[0089] Step S500: While acquiring the real-time water temperature, simultaneously acquire the outdoor temperature;

[0090] Step S600: Generate a historical database based on the real-time water temperature, outdoor temperature, and acquisition time;

[0091] Step S700: Generate an outdoor temperature-delay time comparison table based on the historical database.

[0092] It's important to note that fluctuations in municipal water temperature are often a response to changes in outdoor temperature. While monitoring the municipal water supply temperature, real-time outdoor air temperature data can be simultaneously collected using outdoor ambient temperature sensors. These two sets of data are then linked to the current timestamp, allowing a connection between changes in municipal water supply temperature and external climate conditions. Historical databases record the patterns of municipal water supply temperature changes under different seasons and weather conditions. These databases provide insights into the operational habits of the local municipal heating system, offering fundamental data for predicting changes in municipal heating water temperature. Analysis of these historical databases allows for the summarization of typical durations of short-term fluctuations in municipal water temperature under different outdoor temperatures, thus creating an outdoor temperature-delay time comparison table.

[0093] For example, for outdoor temperatures of -10°C and below, the corresponding delay time is 1 minute because in extremely cold weather, the municipality actively increases the heating temperature, and the municipal heating water temperature may remain at a high temperature for an extended period. For outdoor temperatures of -5°C to 0°C, the corresponding delay time is 10 minutes because in cold weather, the municipality's active increase in heating temperature will not last long. For temperatures of 5°C and above, the corresponding delay time is 1 minute because as the weather warms up, the municipality actively decreases the heating temperature, and the municipal heating water temperature may remain at a low temperature for an extended period.

[0094] Furthermore, step S300 may also include steps S310 to S320:

[0095] Step S310: Based on the outdoor temperature, determine the delay time from the outdoor temperature-delay time lookup table;

[0096] Step S320: Adjust the heating mode according to the delay time and the duration of the heating condition.

[0097] In this embodiment, when it is determined that the heating condition is either overheating or underheating, the corresponding delay time is first looked up from the outdoor temperature-delay time lookup table based on the current outdoor temperature. If the duration of the overheating or underheating condition exceeds the delay time, the heating mode is adjusted according to the heating condition. Specifically, when the heating condition is overheating or underheating, a timer can be started to monitor the duration of the current heating condition. If the duration of the heating condition does not exceed the delay time, the current heating mode is maintained.

[0098] In the technical solution provided in this embodiment, by introducing outdoor temperature and a delay time, instantaneous fluctuations in water temperature are further filtered out. This avoids frequent adjustments to the inlet and outlet valve groups due to normal, temporary overheating or underheating, thereby extending the valve's service life. Simultaneously, when overheating or underheating is expected to persist, it is predicted in advance, and corresponding operations are performed to ensure the safety of the water source heat pump unit and improve the stability of the composite water source heating system and the user's comfort.

[0099] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the composite water source heating method of this application.
