Description

Technical Field

[0001] This utility model relates to the field of energy tower technology, specifically to a multi-source coupled heat pump heat-enhancing energy tower. Background Technology

[0002] In existing technologies, the heat source tower in a heating system relies on the temperature difference between the outdoor and outdoor air to acquire heat. Essentially, it operates in a passive heat absorption mode, similar to the working logic of a naturally aspirated engine. When the ambient temperature drops, the amount of usable heat in the air decreases, leading to a significant decrease in the heat absorption efficiency of the heat source tower. This, in turn, causes a large fluctuation in the thermal efficiency of the heat pump main unit, resulting in a surge in energy consumption and a significant deterioration in heating performance. Furthermore, some types of heat source towers are also affected by air humidity. In cold and dry environments, the heat exchange efficiency is further reduced, making it difficult to meet stable heating demands.

[0003] Therefore, in response to the above-mentioned shortcomings, this utility model presents a multi-source coupled heat pump heat efficiency enhancement energy tower. By adding an auxiliary heating device and an intelligent control system, it breaks through the limitation of traditional heat source towers that only passively absorb heat. It utilizes an electric heating boiler to provide active heat source supplementation, and combines a smart valve dynamic diversion and dual-effect heating mechanism. It can adjust the heating strategy in real time according to the ambient temperature and return water temperature, effectively alleviating the problem of reduced efficiency under severe cold and dry conditions, ensuring stable main mechanism heating efficiency, reducing energy consumption while improving heating reliability, and meeting the urgent needs of the energy tower industry for stable heating function of energy towers. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model to solve its technical problems is: a multi-source coupled heat pump heat efficiency enhancement energy tower, comprising: a mounting frame, the outer wall of which is provided with an auxiliary heating device; the auxiliary heating device includes a smart valve, and the smart valve is fixedly connected to an electric heating boiler through a pipe.

[0005] Preferably, the outer wall of the electric heating boiler is fixedly connected to a flow-guiding solenoid valve via a pipe, the outer wall of the flow-guiding solenoid valve is fixedly connected to a heat exchanger via a pipe, and the outer wall of the heat exchanger is fixedly connected to one end of the outer wall of the smart valve via a pipe. This multi-source coupled heat pump heat-enhancing energy tower takes "precise detection - intelligent diversion - dual-effect heating - hybrid efficiency enhancement" as its core logic. It relies on the mounting frame to fix components such as the electric heating boiler, heat exchanger, and main controller. Through the synergistic effect of the auxiliary heating device and the original energy tower evaporation return mechanism, the system return water temperature is regulated, ultimately ensuring that the heat pump host always operates efficiently at a suitable inlet water temperature. The entire process closely revolves around the functional linkage of each component.

[0006] Preferably, water temperature sensors are fixedly connected to the outer walls of the electric heating boiler and the heat exchanger. The probes of the water temperature sensors are immersed in the system return water of the electric heating boiler and the heat exchanger to detect the temperature of the system return water. After the system starts, the main controller first triggers two types of sensors to collect key data. On the one hand, an ambient temperature sensor installed on the outer wall of the main controller with its probe exposed to the air captures the outdoor ambient temperature in real time to determine whether the operating conditions, such as low temperature and low humidity, may weaken the evaporation return efficiency of the original energy tower. On the other hand, the probes of the water temperature sensors fixed on the outer walls of the electric heating boiler and the heat exchanger are directly immersed in the system return water to accurately detect the initial temperature of the return water that is about to enter the energy tower and confirm whether the return water is lower than the critical temperature required for the efficient operation of the main unit. The two types of sensors transmit the collected temperature data to the chip of the main controller in real time via wires. The chip then performs calculations to determine the operating mode. If the ambient temperature is suitable and the return water temperature is close to the threshold, the "primary energy tower evaporation and return liquid heating as the main mode, with auxiliary heating as a backup" mode is activated first. If the ambient temperature is abnormal, resulting in insufficient evaporation and return liquid efficiency and the return water temperature is lower than the threshold, the "evaporation and return liquid + auxiliary heating dual heating" enhanced mode is triggered.

[0007] Preferably, the inner wall of the heat exchanger is rotatably connected to a stirring rod, and the outer wall of the electric heating boiler is connected to the main controller via a wire. After the operating mode is determined, the chip of the main controller sends a command to the smart valve in the auxiliary heating device. The smart valve, as a core flow distribution component, dynamically divides the system return water, which originally needed to flow directly back to the heat pump host, into two paths: one is the main flow path, which accounts for the majority of the water flow and directly enters the heat exchanger, where it will be mixed and heated subsequently; the other is the auxiliary heating path, which accounts for a small portion of the water flow and is diverted to the electric heating boiler through a pipe, serving as a supplementary heating path in the enhanced mode. The diversion ratio is dynamically adjusted by the main controller according to real-time operating conditions. If the evaporation return efficiency is high, such as when the ambient humidity is suitable, the water volume in the auxiliary heating path is reduced; if the evaporation return efficiency is low, such as when the temperature is low and the environment is dry, the proportion of water in the auxiliary heating path is increased.

[0008] Preferably, an ambient temperature sensor is fixedly connected to the outer wall of the main controller. The probe of the ambient temperature sensor is exposed to the air and is used to detect the ambient temperature. Dual-effect heating is the core component. The main heating path and the auxiliary heating path achieve water temperature increase through different mechanisms. In the auxiliary heating path, the main controller sends a start command to the electric heating boiler. The internal relay is activated to form a circuit for the heating wire. The heating wire generates heat using the current heating effect and transfers it to the diverted return water. The water temperature sensor on the outer wall of the electric heating boiler monitors the water flow temperature after heating in real time. When the water temperature reaches the "high temperature supplement threshold", a feedback signal is sent to the main controller, which adjusts the heating power to avoid energy waste caused by excessively high water temperature.

[0009] Preferably, the outer walls of the electric heating boiler and the heat exchanger are both fixedly connected to the outer wall of the mounting frame. After the double-effect heating is completed, the mixing and efficiency enhancement stage begins. The main controller sends a command to the flow-guiding solenoid valve to open the valve, allowing the high-temperature supplementary water from the electric heating boiler to enter the heat exchanger through a pipe. Inside the heat exchanger, the mainstream return water, which has been initially heated by evaporation, meets the high-temperature supplementary water and is thoroughly mixed under the continuous stirring of the stirring rod, achieving temperature equilibrium through heat exchange. The water temperature sensor on the outer wall of the heat exchanger monitors the mixed water temperature in real time and feeds the data back to the main controller. If the water temperature reaches the "suitable inlet water temperature for the main unit," the mixing is deemed satisfactory; if not, the main controller can fine-tune the flow distribution ratio of the smart valve or the power of the electric heating boiler until the water temperature meets the requirements.

[0010] Preferably, the bottom outer wall of the main controller is fixedly connected to the outer wall of the mounting bracket. The outer wall of the main controller is connected to the outer walls of the smart valve, the flow-guiding solenoid valve, the water temperature sensor, and the ambient temperature sensor via wires. After the mixed water temperature reaches the standard, the system delivers water of suitable temperature to the heat pump host through pipelines. At this time, the host no longer receives low-temperature initial return water, eliminating the need to consume additional energy to raise the inlet water temperature, significantly reducing the operating load, and effectively avoiding the problem of reduced host efficiency under low-temperature conditions. After the water flows through the host for circulation, it becomes "system return water" again, re-entering the detection-diversion-heating process of this energy tower, forming a closed-loop cycle, continuously providing a stable heat source for the efficient operation of the host. Throughout the process, the main controller maintains real-time communication with the smart valve, the flow-guiding solenoid valve, the water temperature sensor, the ambient temperature sensor, and the electric heating boiler via wires, dynamically adjusting operating parameters. If the water temperature is detected to be too high or too low, or if there is abnormal evaporation return, the overload protection will be automatically triggered, such as shutting down the electric heating boiler or entering emergency mode, to ensure equipment safety.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up an auxiliary heating device and an intelligent control system, ensures that the heat pump host is always in the high-efficiency operating range, significantly reducing the overall system power consumption; at the same time, it breaks the temperature limitation of traditional heat source towers, enabling it to stably absorb and supply heat through a dual-effect heating mechanism even in low-temperature and frigid environments, improving the problems of low temperature, low efficiency, and high power consumption of traditional equipment, and making it suitable for a wider range of cold regions.

[0013] 2. By setting up an auxiliary heating device, this utility model enables the energy tower to be used in new heating projects, as well as to be easily attached to old systems for upgrades and renovations. It can also be used as an integrated component for manufacturers to integrate new products, adapting to various scenario needs. Moreover, relying on the clean heating method of electric heating boilers, it conforms to the national policies of "clean energy substitution" and "coal-to-electricity" and meets environmental protection requirements, thus possessing broad market prospects.

[0022] Example:

[0023] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a multi-source coupled heat pump heat efficiency enhancement energy tower, including: a mounting frame 1, and an auxiliary heating device 2 provided on the outer wall of the mounting frame 1; the auxiliary heating device 2 includes a smart valve 20, and the smart valve 20 is fixedly connected to an electric heating boiler 21 through a pipe.

[0024] The outer wall of the electric heating boiler 21 is fixedly connected to a flow guiding solenoid valve 22 via a pipe.

[0025] Water temperature sensors 24 are fixedly connected to the outer walls of the electric heating boiler 21 and the heat exchanger 23. The probe of the water temperature sensor 24 is immersed in the system return water of the electric heating boiler 21 and the heat exchanger 23 to detect the temperature of the system return water.

[0026] A stirring rod 25 is rotatably connected to the inner wall of the heat exchanger 23, and the outer wall of the electric heating boiler 21 is connected to the main controller 26 via a wire.

[0027] An ambient temperature sensor 27 is fixedly connected to the outer wall of the main controller 26. The probe of the ambient temperature sensor 27 is exposed to the air and is used to detect the ambient temperature. The outer walls of the electric heating boiler and the heat exchanger 23 are both fixedly connected to the outer wall of the mounting bracket 1.

[0028] The bottom outer wall of the main controller 26 is fixedly connected to the outer wall of the mounting bracket 1. The outer wall of the main controller 26 is connected to the outer wall wires of the smart valve 20, the flow guiding solenoid valve 22, the water temperature sensor 24 and the ambient temperature sensor 27 through wires.

[0029] Working principle:

[0030] This multi-source coupled heat pump heat enhancement energy tower takes "precise detection - intelligent diversion - dual-effect heating - hybrid efficiency enhancement" as its core logic. It relies on the mounting frame 1 to fix components such as electric heating boiler 21, heat exchanger 23, and main controller 26. Through the synergistic effect of auxiliary heating device 2 and the original energy tower evaporation return mechanism, the system return water temperature is regulated, ultimately ensuring that the heat pump host always operates efficiently at a suitable inlet water temperature. The entire process is closely centered around the functional linkage of each component.

[0031] The ambient temperature sensor 27 is a DHT22, whose probe is exposed to the air to detect the ambient temperature; the water temperature sensor 24 is a PT100, which is immersed in the system return water of the electric heating boiler 21 and heat exchanger 23 to detect the temperature of the system return water; the chip in the main controller 26 is a CETCLQFP48, which is used to process sensor information and control the smart valve 20 and the flow guiding solenoid valve 22; the relay is a SRD-05VDC-SL-C, which works with the chip to control the heating wire of the electric heating boiler 21; and the smart valve 20 is a Q945F-16C, which is used to divert the system return water.

[0032] After the system starts up, the main controller 26 first triggers two types of sensors to collect key data. On the one hand, the ambient temperature sensor 27, installed on the outer wall of the main controller 26 with its probe exposed to the air, captures the outdoor ambient temperature in real time to determine whether the operating conditions, such as low temperature and low humidity, may weaken the efficiency of the original energy tower's evaporation and return liquid. On the other hand, the water temperature sensor 24, fixed on the outer walls of the electric heating boiler 21 and the heat exchanger 23 respectively, has its probe directly immersed in the system's return water to accurately detect the initial temperature of the return water about to enter the energy tower, confirming whether the return water is below the critical temperature required for the efficient operation of the main unit. The two types of sensors transmit the collected temperature data to the chip of the main controller 26 in real time via wires. The chip performs calculations to determine the operating mode—if the ambient temperature is suitable and the return water temperature is close to the threshold, the "primary energy tower evaporation and return liquid heating as the main mode, with auxiliary heating as a backup" mode is activated first; if the ambient temperature is abnormal, resulting in insufficient evaporation and return liquid efficiency, and the return water temperature is below the threshold, the "evaporation and return liquid + auxiliary heating dual heating" enhanced mode is triggered.

[0033] Once the operating mode is determined, the chip in the main controller 26 sends a command to the smart valve 20 in the auxiliary heating device 2. The smart valve 20, as the core flow distribution component, dynamically divides the system return water, which would normally flow directly back to the heat pump unit, into two paths: one is the main flow path, which accounts for the majority of the water flow and directly enters the heat exchanger 23, where it will be mixed and heated; the other is the auxiliary heating path, which accounts for a smaller portion of the water flow and is diverted through pipes to the electric heating boiler 21 as a supplementary heating path in the enhanced mode. The diversion ratio is dynamically adjusted by the main controller 26 based on real-time operating conditions. If the evaporation return efficiency is high, such as when the ambient humidity is suitable, the water volume in the auxiliary heating path is reduced; if the evaporation return efficiency is low, such as when the temperature is low and the environment is dry, the proportion of water in the auxiliary heating path is increased.

[0034] Dual-effect heating is the core component. The main heating circuit and the auxiliary heating circuit achieve water temperature increase through different mechanisms. In the auxiliary heating circuit, the main controller 26 sends a start command to the electric heating boiler 21. The internal relay activates to form a circuit for the heating wire. The heating wire generates heat using the current heating effect and transfers it to the diverted return water. The water temperature sensor 24 on the outer wall of the electric heating boiler 21 monitors the water flow temperature after heating in real time. When the water temperature reaches the "high temperature supplement threshold", a feedback signal is sent to the main controller 26, which adjusts the heating power to avoid excessive water temperature and energy waste.

[0035] After the dual-effect heating is completed, the mixing and enhancement stage begins. The main controller 26 sends a command to the flow-guiding solenoid valve 22 to open the valve, allowing the high-temperature makeup water in the electric heating boiler 21 to enter the heat exchanger 23 through the pipe. Inside the heat exchanger 23, the main return water and the high-temperature makeup water meet and are fully mixed under the continuous stirring of the stirring rod 25, achieving temperature equilibrium through heat exchange. The water temperature sensor 24 on the outer wall of the heat exchanger 23 monitors the mixed water temperature in real time and feeds the data back to the main controller 26. If the water temperature reaches the "suitable inlet water temperature for the main unit," the mixing is deemed satisfactory. If it does not meet the standard, the main controller 26 can fine-tune the flow ratio of the smart valve 20 or the power of the electric heating boiler 21 until the water temperature meets the requirements.

[0036] Once the mixed water temperature reaches the target, the system delivers water of suitable temperature to the heat pump unit through pipelines. At this point, the unit no longer receives low-temperature initial return water, eliminating the need for additional energy to raise the inlet water temperature, significantly reducing the operating load and effectively avoiding the problem of reduced unit efficiency under low-temperature conditions. After circulating through the unit, the water becomes "system return water" again, re-entering the detection-diversion-heating process of this energy tower, forming a closed-loop cycle and continuously providing a stable heat source for the efficient operation of the unit. Throughout the process, the main controller 26 maintains real-time communication with the smart valve 20, the flow-guiding solenoid valve 22, the water temperature sensor 24, the ambient temperature sensor 27, and the electric heating boiler 21 via wires, dynamically adjusting operating parameters. If excessively high or low water temperatures, abnormal evaporation return, or other abnormalities are detected, overload protection such as shutting down the electric heating boiler 21 or entering emergency mode will be automatically triggered to ensure equipment safety.

[0037] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
