Description

Technical Field

[0001] The present disclosure belongs to the technical field of heating control, and in particular, relates to a method, system and electronic equipment for joint operation control of different types of heating equipment. Background Art

[0002] With the improvement of living quality, more and more areas have installed heating systems to provide a warm and comfortable living and working environment when the temperature drops in the cold winter. The demand for heating is increasing, and a variety of heating methods have emerged. For example, the most common heating methods currently include air source heat pumps, solid thermal storage electric boilers, and small electric heaters.

[0003] Various heating methods have their own advantages and disadvantages: the air source heat pump (ASHP) heating method is a heat pump system that uses the outside air as a heat source, which has the advantages of low initial investment, flexible installation, and energy saving. Although the development prospects of air source heat pumps are promising, in relatively cold areas, the low outdoor temperature environment will increase the compression ratio of air source heat pump technology, which will have a certain impact on the normal operation of the unit. The solid thermal storage electric boiler (STES-HP) method refers to a heat pump system that stores and releases heat through thermal storage sediments. It uses low-valley electricity at night for heating, and stores heat energy in water, magnesium bricks, molten salt or other media, and releases heat during the daytime peak and flat electricity price period. It has the advantages of electricity peak shaving and valley filling, high outlet water temperature, low operating costs, and high reliability. The heating effect is not affected by the external ambient temperature, and it can still maintain a stable output even in extremely cold weather. However, the initial investment is high, so when using thermal storage electric heating, you need to pay attention to the local electricity price.

[0004] In the current heating system, different heating systems may exist in the same area, and in the actual heating operation control, different heating systems are controlled independently. For example, the heating control of the air source heat pump type will not consider the heating of the solid thermal storage electric boiler type.

[0005] Since different types of heating methods have their own advantages and disadvantages, separate operation control is used without considering joint operation control. Various types of heating system equipment are not coordinated with each other, and their respective advantages cannot be fully utilized, and energy saving is also unsatisfactory.

[0006] Therefore, a method and system for joint operation control of different types of heating equipment is needed to comprehensively consider the advantages of different types of heating equipment and reduce their respective disadvantages, especially in areas where multiple types of heating equipment coexist, so as to effectively achieve the purpose of energy saving. Summary of the invention

[0007] To solve the above problems, the present disclosure provides a method, system and device for joint operation control of different types of heating equipment, which can comprehensively consider the characteristics of different types of heating equipment and has great advantages in economy and energy saving compared with the control of a single type of heating equipment.

[0008] To achieve the above objectives, the present disclosure provides a method for controlling the joint operation of different types of heating equipment, the method comprising:

[0009] Measuring return water temperature of heating systems;

[0010] Determine whether the return water temperature is within the preset temperature range. If the return water temperature is within the preset temperature range, control the activation of the first type of heating equipment for heating and heat release; if the return water temperature is lower than the preset temperature range, control the increase of the heat release of the second type of heating equipment; if the return water temperature is higher than the preset temperature range, control the first type of heating equipment to reduce the heating amount.

[0011] Furthermore, if the return water temperature is lower than the preset temperature range, controlling to increase the heat release of the second type of heating equipment includes:

[0012] If the return water temperature is lower than the preset temperature range within a predetermined time, controlling to increase the heat release of the second type of heating equipment;

[0013] If the return water temperature is lower than the preset temperature range for more than a predetermined time, the control activates the first type of heating equipment to perform heating and heat release.

[0014] Furthermore, if the return water temperature is higher than the preset temperature range, the first type of heating equipment is controlled to reduce the heating amount.

[0015] The heating amount of the first type of heating equipment is adjusted.

[0016] Furthermore, the first type of heating equipment is a heat storage boiler; and / or,

[0017] The second type of heating equipment is an air source heat pump, which increases the heat release of the air source heat pump by increasing the air energy of the air source heat pump.

[0018] Furthermore, the preset temperature range is 35°-40°.

[0019] Based on the same inventive concept, the embodiment of the present disclosure also provides a system for controlling the joint operation of different types of heating equipment, the system comprising a temperature sensor and a control device.

[0021] The control device is configured to receive the return water temperature sent by the temperature sensor and determine whether the return water temperature is within a preset temperature range. If the return water temperature is within the preset temperature range, the control device enables the first type of heating equipment to provide heating and heat release; if the return water temperature is lower than the preset temperature range, the control device increases the heat release of the second type of heating equipment; if the return water temperature is higher than the preset temperature range, the control device reduces the heat supply of the first type of heating equipment.

[0022] Furthermore, if the return water temperature is lower than the preset temperature range, controlling to increase the heat release of the second type of heating equipment includes:

[0023] If the return water temperature is lower than the preset temperature range within a predetermined time, controlling to increase the heat release of the second type of heating equipment;

[0024] If the return water temperature is lower than the preset temperature range for more than a predetermined time, the control activates the first type of heating equipment to perform heating and heat release.

[0025] Furthermore, if the return water temperature is higher than the preset temperature range, the first type of heating equipment is controlled to reduce the heating amount.

[0026] The heating amount of the first type of heating equipment is adjusted.

[0027] Furthermore, the first type of heating equipment is a heat storage boiler; and / or,

[0028] The second type of heating equipment is an air source heat pump, which increases the heat release of the air source heat pump by increasing the air energy of the air source heat pump.

[0029] Based on the same inventive concept, an embodiment of the present disclosure also provides an electronic device, including: a memory, a processor; the processor is used to read and execute a computer program stored in the memory to implement the aforementioned method of joint operation control of different types of heating equipment.

On the basis of maintaining a high degree of integration of the heating system, the overall collaborative control capability of the heating system as a whole with different types of heating systems can be improved, and it has high robustness. Moreover, the operation of the corresponding types of heating equipment is controlled based on different conditions, and the control operation is more flexible.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] Figure 1FIG. 2 is a flow chart showing a method for controlling the joint operation of different types of heating equipment according to an embodiment of the present disclosure. Figure 1 Described, measure the return water temperature of the heating system; determine whether the return water temperature is within the preset temperature range, if the return water temperature is within the preset temperature range, control the activation of the first type of heating equipment to heat and release heat; if the return water temperature is lower than the preset temperature range, control the increase of the heat release of the second type of heating equipment; if the return water temperature is higher than the preset temperature range, control the first type of heating equipment to reduce the heat supply.

[0041] It should be noted that in the above steps of the embodiment of the present disclosure, judging whether the return water temperature is within the preset range, higher than the preset range, or lower than the preset range and executing the corresponding processing steps are not necessarily performed in the above order. As long as the judgment and execution of the corresponding steps can be achieved, they are applicable to the present disclosure.

[0042] In the examples disclosed in this disclosure, the heating method of the heat storage boiler type and the heating method of the air source heat pump type are used as examples for exemplary description. Figure 2 The schematic diagram of the system architecture of the coexistence of the heat storage boiler and the air source heat pump type heating equipment according to the embodiment of the present disclosure is shown. Figure 2 As shown, the thermal storage boiler and the air source heat pump heating equipment supply heating hot water to the heating area through the water inlet pipe. After the heating hot water flows through the hot water pipe in the heating area, the heating hot water is discharged from the heating area through the water outlet. The water supply of the corresponding heating equipment can be turned on and off by the valves on the water outlet pipe and the water inlet pipe of each type of heating equipment. In the embodiment of the present disclosure, a temperature measuring device for detecting the outlet water temperature can be arranged on the outlet pipe, such as a temperature sensor. The temperature sensor can measure the water temperature of the outlet pipe at any time in real time, at a fixed time, or based on the instruction of the control device. The control device can adopt an industrial computer, an ordinary computer, a processor with processing capability, etc., which receives the temperature data of the temperature sensor and performs corresponding judgment and processing based on the obtained temperature data.

[0043] Figure 3 The following is a schematic flow chart showing the steps of the method for executing the joint operation control by the control device according to the embodiment of the present disclosure. Figure 3As shown, after the control device is started, the internal program self-check is performed to complete the startup of the device. After the control device is started, the return water temperature of the outlet pipe of the heating area is obtained from the temperature sensor. The timing of obtaining the return water temperature can be set according to actual conditions. For example, the temperature sensor measures the return water temperature of the outlet pipe in real time and sends the obtained return water temperature data to the control device; in some cases, considering the energy-saving benefits, the control device can be set to periodically obtain the return water temperature value from the sensor, or the control device can send a measurement instruction to the sensor to obtain the return water temperature value when necessary. This is not limited in the embodiments of the present disclosure.

[0044] After the control device obtains the return water temperature, it compares the return water temperature with a preset value (e.g., a preset temperature range). In the embodiment of the present disclosure, 35°-40° is used as an example for explanation, but this preset temperature range can be set in advance or modified in time according to actual conditions.

[0045] The control device compares the obtained return water temperature with the above-mentioned preset temperature range. If the return water temperature is less than 35°, it means that the heat of the heating area is low, which will cause the comfort of the heating area to decrease. At this time, the control device controls the start of the air source heat pump, so that the air energy of the air source heat pump increases, so as to control the air source heat pump to provide heat energy, increase the water temperature of the water inlet pipe through the air source heat pump, and increase the heat supply of the heating area. Considering that there will be a certain time delay from increasing the temperature of the water inlet pipe to improving the adaptability of the outlet pipe temperature, in the embodiment of the present disclosure, a predetermined time can be set, and the return water temperature of the outlet pipe is measured and obtained in real time within the predetermined time. If the return water temperature of the outlet pipe still does not reach 35° within the predetermined time, the control starts the heat storage boiler to realize the heat storage boiler to increase the heat supply of the water inlet pipe, and then the heat storage boiler is continuously used for heating and temperature increase. In the embodiment of the present disclosure, the predetermined time can be set according to actual conditions, such as the length of the pipeline in the heating area, the weather temperature of the day, etc., and in the disclosed embodiment, it is not limited to a specific predetermined time. In the disclosed embodiment, control can also be performed by setting a predetermined number of times. For example, if the number of times the air kinetic energy is increased exceeds the predetermined number of times and the outlet water temperature still cannot reach above 35°, the control device controls the start-up of the heat storage boiler for heating.

[0046] If the return water temperature is greater than 35°, it means that the heat supply is too large, resulting in a waste of resources and not meeting the energy-saving requirements. At this time, the heat supply can be reduced by reducing the heat release of the heat storage boiler to achieve the purpose of saving heating costs. After that, the temperature of the heating area can be adjusted according to the heat supply of the heat storage boiler.

[0047] If the return water temperature is between 35°-40°, a heat storage boiler is used for heating.

[0048] In the disclosed embodiment, a joint control system is used to jointly control different types of heating methods. In the same scenario, the heat demand is analyzed based on the regional heating heat demand and the operating characteristics of the heating equipment (such as solid thermal storage, air source heat pump). According to these demands, different heating equipment can be used for heating at the target temperature by adjusting the preset temperature range. Furthermore, the operation strategy can be optimized according to the power consumption period (for example, adjusting the above-mentioned preset temperature range, predetermined time, predetermined number of times, etc.), and the energy consumption (power consumption) of the thermal storage and direct heating equipment can be jointly controlled and operated comprehensively to achieve energy-saving control, improve energy supply effect and reduce energy consumption.

[0049] In the disclosed embodiment, since the return water temperature of the outlet pipe is measured and different types of heating equipment are controlled to provide heating based on the return water temperature, it is objectively possible to analyze whether different heating equipment has failed. For example, if the air energy of the air source heat pump is increased, but the return water temperature of the outlet pipe has not reached a predetermined temperature (for example, 35°), it can be determined that the air source heat pump has failed, and an alarm message can be issued at this time.

[0051] It should be noted that the embodiment of the present disclosure takes the joint control of two types of heating equipment as an example for illustrative explanation, but it is not limited to the two types in the example, and other types of heating methods are also applicable to the present disclosure; and the embodiment of the present disclosure is not limited to only two types, and more than two heating methods are also applicable to the present disclosure.
