[0002] At present, the scale of urban centralized heating is getting larger and larger, high-rise buildings are rising, multi-energy complementary multi-heat source networking and distributed transmission and distribution systems are emerging, and the operating conditions of heating systems are becoming more and more complex.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, this embodiment provides a structural schematic diagram of a heating energy-saving device, including: a single-chip microcomputer, a memory, a communication module, a flow sensor, a first non-contact water level sensor, a second non-contact water level sensor and a temperature acquisition module, wherein the temperature acquisition module includes a return water temperature sensor and a supply water temperature sensor, and the flow sensor is fixedly mounted on the meter body. The supply water temperature sensor is fixedly mounted on the inner wall of the water supply pipeline, and the return water temperature sensor is fixedly mounted on the inner wall of the return water pipeline. The return water temperature sensor and the supply water temperature sensor are connected to the single-chip microcomputer through the communication module, and the temperature data of the water in the heating system can be monitored through the return water temperature sensor and the supply water temperature sensor. The first non-contact water level sensor and the second non-contact water level sensor can monitor in real time whether there is water at the highest point of the water supply pipeline and the return water pipeline, and whether the water volume and heat meet the requirements. The first non-contact water level sensor is a return water non-contact full water sensor, the second non-contact water level sensor is a supply water non-contact full water sensor, the heating energy-saving device is also provided with a power supply, a display and a keyboard, the keyboard is electrically connected to the display, and the power supply and the display are electrically connected to the single-chip computer. The first non-contact water level sensor and the second non-contact water level sensor are respectively fixedly installed at the top position of the water supply pipeline and the top position of the return water pipeline, and the communication module, the memory, the flow sensor, the temperature acquisition module, the first non-contact water level sensor and the second non-contact water level sensor are respectively connected to the single-chip computer for communication.

[0025] The present application solves the problem of whether the highest point (i.e. the most unfavorable point) of the heating system meets the functional requirements of the fixed-point measurement, thereby providing a guarantee for the safe and refined operation of the heating system.

[0026] In this embodiment, the flow sensor is fixedly installed on the inner wall of the water supply pipe or the return pipe of the heating system. It is used to monitor the flow and transmit the monitored data to the single chip microcomputer.

[0027] When in use, the real-time monitored flow data, temperature data and pre-set data are sent to the local or remote display for display after being processed by the single-chip microcomputer. Specifically: the flow sensor, return water temperature sensor, water supply temperature sensor, first non-contact water level sensor, and second non-contact water level sensor collect the flow signal, supply and return water temperature signal, and supply and return water full water signal and send them to the single-chip microcomputer for processing. The single-chip microcomputer senses whether the flow of the user at the highest point (the most unfavorable point) meets the preset requirements, whether the heat meets the preset requirements, and whether the highest point is full of water based on the flow signal, each temperature signal, and each full water signal information. When there is water at the top of the water supply and return pipes of the heating system, and it is full of water, and there is flow at the highest point, and it can reach the set heat and flow while being full of water and having flow, the heating function can be met, and there is no need for artificial exhaust. On the contrary, if it is not full of water, manual and automatic exhaust and adjustment of the water supply pump head are required to make the supply return system full of water (the water supply pump head of the system can be calibrated in this way), and then the distribution flow and heat are increased to meet the heating function. Full water is a necessary condition for heating. If there is flow, it can be proved that it is running with full water. The full water and flow can be used to verify whether it is full of water. The actual situation is that the user's indoor heating device cannot achieve full water operation heating, and this application can minimize energy consumption while meeting full water operation heating. When the heating system is full of water and the set flow and full water reach the optimal state, the cost of manual on-site exhaust can be reduced, the distribution energy consumption can be reduced, the water supply power consumption can be reduced, and the constant pressure value of the complex system can be found in the fastest way. It can achieve heat balance, flow balance and pressure balance in actual heating.

[0028] Embodiment 2:

[0029] refer to Figure 2 , is another structural schematic diagram of a heating energy-saving device, including a meter body, a flow sensor, a first non-contact water level sensor, a second non-contact water level sensor, a return water temperature sensor, and a supply water temperature sensor. A single-chip microcomputer, a memory, and a communication module are arranged inside the meter body. The communication module, the memory, the flow sensor, the return water temperature sensor, the supply water temperature sensor, the first non-contact water level sensor, and the second non-contact water level sensor are respectively connected to the single-chip microcomputer in communication. The model of the single-chip microcomputer is DVP-12SE. The memory is also connected to the communication module in communication.

[0030] In this embodiment, the heating energy-saving device also includes an automatic exhaust valve, which will float when there is water, and the automatic exhaust valve is communicatively connected to the single-chip microcomputer. The automatic exhaust valve is a device used to exhaust the air during the operation of the heating system. During the operation of the heating system, the many adverse effects brought about by the gases released when the water is heated, such as hydrogen and oxygen, will damage the system and reduce the thermal effect. If these gases cannot be discharged in time, many adverse consequences will occur. Therefore, the air is exhausted through the automatic exhaust valve. At the same time, the application also provides a shut-off valve, which is fixedly installed on the main return water pipeline and the main outlet water pipeline of the heating system. When the automatic exhaust valve fails, the shut-off valve is activated to provide protection for the heating system.

[0031] In this embodiment, the heating energy-saving device also includes a plurality of non-metallic pipes, which are adhered to the outer wall of the water supply pipeline or / and the loop pipeline, and a flow sensor, a first non-contact water level sensor, a second non-contact water level sensor or / and a temperature acquisition module are fixedly installed in the non-metallic pipe. When the return water pipeline or the water supply pipeline is set as a metal pipe, some metal pipes can shield the sensor and affect the working effect. Therefore, the present application sets a plurality of non-metallic pipes, and opens non-metallic pipes near the position where each sensor should be placed. The non-metallic pipe can be a sealed one-section type, and each sensor is placed inside it. The above scheme can accurately measure the data of each sensor without affecting the working effect. If the pipeline itself is non-metallic, it does not need to be shielded, and each sensor can be placed directly in the original pipeline.

[0032] This application utilizes a meter body, a flow sensor, a return water temperature sensor, a water supply temperature sensor, a first non-contact water level sensor and a second non-contact water level sensor to work in coordination, and is able to measure whether the highest point of the heating system meets the preset requirements, thereby providing key data for the operation of the heating system. By installing and using the device, the existing system design and operation constant pressure verification can be quickly implemented, which can achieve greater energy saving than the existing system, and quickly solve the industry's pain points of not knowing whether the highest point of the system is optimally full of water and whether the flow rate is optimal. It can also solve the high-point information perception of the multi-pump heating system and the single-item analysis and decoupling analysis of the constant pressures of different highest points of the system under different conditions and the constant pressures of each point, providing the most accurate data to achieve energy saving in heating.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
