Abstract

This invention discloses an integrated high-efficiency heat exchange system, which connects an indoor unit, an outdoor unit, and air conditioning terminal equipment via pipelines. In the indoor unit's internal circulation pipeline, a water purification device is connected before or after the mixing device and circulation pump.

The branch formed by the water purification device prevents dry burning, purifies water quality, removes scale, and provides a minimum flow loop for the system, helping to stabilize system pressure. Multiple fan coil units are installed in the air conditioning terminal equipment, and a resistance sensor is installed before the circulation pump. When the number of fan coil units operating changes, the pump speed changes as the number of fan coil units decreases. The air purification device in the indoor unit draws indoor air into the unit, adsorbing pollutant molecules in the micropores of activated carbon, while clean air is blown back into the room. The circulation pump in this system is a shielded pump, which has low operating friction and low noise.

Description

Technical Field

[0001] This invention relates to the field of indoor heating technology, and specifically to an integrated high-efficiency heat exchange system for indoor heating and air environment regulation. Background Technology

[0002] As people's living standards continue to improve, their demands for indoor environments have gone far beyond just temperature. In addition to basic cooling and heating, people now have higher requirements for the comfort and health benefits of such heating equipment.

[0003] 1. Existing heat exchange systems of this type have high operating power and cannot be fine-tuned according to the actual needs of the user. The units always operate at high load, resulting in energy waste. 2. Existing equipment of this type lacks air conditioning function. Special purification equipment needs to be installed at the end of the equipment to achieve gas regulation, which increases the installation and operating costs. 3. Existing equipment of this type uses circulating water multiple times and operates in a state of replenishing water when it is low. Scale and impurities in the circulating water cannot be removed. After years of operation, it is easy to cause blockage inside the equipment. At the same time, this circulating water is also a breeding ground for dirt and bacteria, which can easily pollute the external environment. 4. Existing equipment of this type is noisy when operating, and the noise pollution affects the user experience.

[0004] In view of the shortcomings of the existing technology, as someone skilled in the art, how can we improve the existing heating system of this kind through technological improvements, so that it can reduce operating noise, flexibly adjust operating power, realize intelligent adjustment of operating energy consumption, and filter the circulating liquid in real time to avoid environmental pollution caused by the accumulation of dirt and bacteria in the circulating water. Summary of the Invention

[0005] To overcome the aforementioned deficiencies in the prior art, this invention provides an integrated high-efficiency heat exchange system. This device aims to provide a quiet, clean, and efficient heat exchange system solution. The technical solution involves: installing a water purification device on the branch pipe between the mixing device and the circulating pump to purify a portion of the circulating water before it is incorporated into the circulation system; achieving purification of the internal water circulation while preventing the circulating pump from burning out; and then, by setting up internal sensors to feed back the water usage signal from the terminal units to the water pump, the pump speed is adjusted synchronously with the number of terminal fan coil units activated, gradually reducing the pump speed and achieving intelligent adjustment.

[0006] An integrated high-efficiency heat exchange system includes an indoor unit, an outdoor unit, and air conditioning terminal equipment;

[0007] The indoor unit is equipped with pipes and a circulation pump that connects the heat exchange device and the mixing device; the indoor unit is also equipped with an air purification device; a water purification device is installed on the pipes connected to the mixing device and the circulation pump on the front or back side.

[0008] The mixing device is connected to an air conditioning terminal device at its rear. The air conditioning terminal device includes several fan coil units, and a control valve is provided for each fan coil unit. A circulation pump is connected to the rear of the air conditioning terminal device through a resistance sensor.

[0009] The heat exchange device is connected to the outdoor unit;

[0010] The indoor unit, outdoor unit, and air conditioning terminal equipment are connected and controlled by a wired controller.

[0011] Temperature sensors are installed on the water supply pipe and return pipe of the air conditioning terminal equipment, and the operating power of the outdoor unit is adjusted by measuring the temperature.

[0012] The air purification device includes a housing with a primary filter and a terminal filter installed on both sides. Inside the housing, from the air inlet to the air outlet, are a purification fan, activated carbon fiber mesh, ultraviolet lamp bundle, and negative ion generator. An air quality sensor is installed indoors or near the air outlet of the air purification device. When the air quality sensor detects pollution or the user manually activates the device, the purification fan starts. Indoor air is drawn into the indoor unit and flows through the multi-stage filters, activated carbon fiber mesh, ultraviolet lamp bundle, and negative ion generator. Pollutant molecules are adsorbed into the micropores of the activated carbon, and clean air is blown back into the room. The activated carbon filter needs to be replaced regularly (usually every 6-12 months, depending on the pollution level) to prevent it from becoming saturated and ineffective.

[0013] The water purification device includes a barrel-shaped outer shell with an inlet and an outlet at both ends. Both the inlet and outlet are threaded and connected to an external pipe via the threads. After periodic operation, the water purification device can be removed for maintenance and replacement.

[0014] The barrel-shaped outer shell contains water purification filter media, which includes a silicon phosphate crystal anti-scaling agent, magnetic filter media, and activated carbon particles. Each pair of adjacent filter media is separated by a plastic grid. The silicon phosphate crystal anti-scaling agent accounts for 50%, the magnetic filter media accounts for 30%, and the activated carbon particles account for 20%. The various water purification filter media work together.

[0015] The aforementioned silicon phosphate crystal anti-scaling agent plays a role in removing scale and inhibiting corrosion; hard scale is transformed into soft scale or suspended matter that is easily washed away by water flow, preventing hard scale layers from adhering to the inner walls of pipes, water pumps, heat exchangers and fan coil units.

[0016] The magnetic filter media described herein serves to prevent and remove scale, inhibit corrosion, and purify suspended solids.

[0017] The activated carbon granules are used to adsorb trace amounts of dissolved organic matter, additive decomposition products, or odors in circulating water or makeup water.

[0018] The circulating pump is a canned motor pump, and the motor rotor and impeller of the circulating pump are integrated into one structure. The outer wall of the circulating pump is completely covered by the shielding sleeve. This design eliminates the need for a mechanical seal, resulting in low operating friction and inherently low noise.

[0019] The inner wall of the indoor unit's casing is lined with sponge sound-absorbing material, which can absorb and block the vibration noise generated by the water pump and water flow from propagating into the room.

[0020] The beneficial effects of this invention, after the above structural configuration, are as follows:

[0021] This invention connects the indoor unit, outdoor unit, and air conditioning terminal equipment via pipelines;

[0022] In the indoor unit's internal circulation pipeline, a water purification device is connected to the mixing device and the circulation pump, either before or after it. The liquid circulates repeatedly in the closed pipeline, without direct contact with the atmosphere, reducing corrosion and the entry of impurities. The branch circuit formed by the water purification device can prevent dry burning, purify water quality, and remove scale. At the same time, it also provides a minimum flow loop for the system, which helps to stabilize the system pressure.

[0023] Multiple fan coil units are installed in the air conditioning terminal equipment and a resistance sensor is installed in front of the circulating pump. When the number of fan coil units in operation changes, the amount of water entering the circulating pump decreases. The resistance sensor in front of the pump feeds back a signal to the water pump, that is, the water pump speed changes as the number of fan coil units in operation decreases, thus achieving low-energy operation.

[0024] The air purification device in the indoor unit draws indoor air into the unit, where it flows through multi-stage filters, activated carbon fiber mesh, ultraviolet lamp bundle, and negative ion generator. Pollutant molecules are adsorbed in the micropores of the activated carbon, and the clean air is then blown back into the room.

[0025] The circulating pump in this system is a canned pump, which does not require a mechanical seal, has low operating friction, and low noise. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] Example 1: An integrated high-efficiency heat exchange system, such as Figure 1 As shown, it includes indoor unit 2, outdoor unit 3, and air conditioning terminal equipment 1;

[0035] The indoor unit 2 is connected to the heat exchange device 22 and the mixing device 23 by a circulation pump 21 connected in series through a pipeline; the indoor unit 2 is also equipped with an air purification device 4; a water purification device 24 is connected to the pipeline on the front or rear side of the mixing device 23 and the circulation pump 21; in this embodiment, it is installed at the water inlet end on the front side of the circulation pump 21.

[0036] The mixing device 23 is connected to an air conditioning terminal device 1 at its rear. The air conditioning terminal device 1 includes three fan coil units 11, each with a control valve 12. The fan coil units 11 are located in each room and blow the energy from the cold / hot water coils into the room through the fan. The air conditioning terminal device 1 is connected to a circulation pump 21 at its rear via a resistance sensor 25. The resistance sensor 25 feeds back the signal to the speed controller of the circulation pump 21. The circulation pump 21 has three speed settings: high, medium, and low flow rate. When the pressure measured by the resistance sensor 25 is low, the flow rate is increased; conversely, the flow rate is decreased, thereby accurately matching the real-time load of the terminal.

[0037] The heat exchange device 22 inside the indoor unit 2 is connected to the outdoor unit 3. The heat exchange device 22 transfers the cold / heat generated by the outdoor unit to the indoor circulating water system. This heat exchange device 22 uses a shell-and-tube high-efficiency tank heat exchanger, separating the primary side (outdoor unit side) and the secondary side (indoor unit side) water circuits. The outdoor unit 3 is equipped with a compressor. The outdoor unit 3 is typically an air-cooled heat source unit, producing chilled or hot water.

[0038] The indoor unit 2, outdoor unit 3, and air conditioning terminal equipment 1 are connected by a wired controller 5 and can be automatically controlled.

[0039] Temperature sensor I6 and temperature sensor II26 are respectively installed on the water supply pipe and return pipe of the air conditioning terminal device 1, and the operating power of the outdoor unit 3 is adjusted by measuring the temperature difference.

[0040] The purpose of installing the aforementioned water purification device 24 is as follows:

[0041] To prevent dry burning: Even if the control valves 12 of all fan coil units 11 are closed, some water will still flow through this bypass back to the circulation pump 21, ensuring that there is always water flowing through the circulation pump 21 and avoiding damage from dry burning.

[0042] Water purification: It continuously filters and adsorbs about 1 / 4 of the circulating water in the system. The ring-shaped adsorption materials of different materials remove impurities, metal ions, microbial slime and other substances from the water, protecting pipes and equipment from corrosion and scaling.

[0043] Bypass voltage regulation: Provides a minimum flow loop for the system, which helps stabilize system pressure, especially when there are large changes in the terminal load.

[0044] The aforementioned circulating pump 21 is a canned pump. The motor rotor and impeller of the circulating pump 21 are an integral structure. The outer wall of the circulating pump 21 is completely covered by the shielding sleeve. This design does not require a mechanical seal, has low operating friction, and inherently low noise.

[0045] The inner wall of the indoor unit 2 casing is lined with sponge sound-absorbing material, which can absorb and block the vibration noise generated by the water pump and water flow from spreading into the room.

[0046] Select a canned motor pump. The motor rotor and impeller of this type of pump are integrated and completely sealed within the shielding sleeve, eliminating the need for a mechanical seal, resulting in low operating friction and inherently low noise.

[0047] Sponge sound-absorbing material is applied to the inner wall of the indoor unit casing to effectively absorb and block the vibration noise generated by the water pump and water flow from spreading into the room.

[0048] Example 2: Based on the above examples, the present invention further discloses the internal structure of an air purification device, such as... Figure 4As shown, the air purification device 4 includes a device housing 40, which is formed by bending steel sheet.

[0049] A primary filter 41 and a terminal filter 46 are installed on both sides of the housing 40, respectively. Inside the housing 40, from the air inlet side to the air outlet side, there are a purification fan 42, an activated carbon fiber mesh 43, an ultraviolet lamp bundle 44, and a negative ion generator 45. An air quality sensor is installed indoors or near the air inlet of the air purifier 4, in conjunction with the air purifier 4. When the air quality sensor detects pollution or the user manually turns it on, the purification fan 42 starts; indoor air is drawn into the indoor unit 2 and flows through the two-stage filter, the activated carbon fiber mesh 43, the ultraviolet lamp bundle 44, and the negative ion generator 45. Pollutant molecules are adsorbed in the micropores of the activated carbon, and clean air is blown back into the room. The activated carbon filter needs to be replaced regularly (usually every 6 to 12 months, depending on the pollution level) to prevent it from becoming saturated and ineffective.

[0050] The function of activated carbon fiber mesh 43:

[0051] Activated carbon has a highly developed pore structure (especially micropores) and a huge specific surface area (up to 1000 m² / g or more), which gives it extremely strong adsorption capacity.

[0052] 1) Main objects to be removed

[0053] Volatile organic compounds (TVOC): such as formaldehyde, benzene, toluene, xylene, and other chemical pollutants from decoration and furniture.

[0054] Odor molecules: smoke, cooking fumes, pet odors, musty smells, etc.

[0055] Some semi-volatile organic compounds and ozone.

[0056] 2) Workflow in the system

[0057] When the air quality sensor detects pollution or the user manually activates the system, the purification fan starts. Indoor air is drawn into the indoor unit and flows through the activated carbon filter / layer. Pollutant molecules are adsorbed into the micropores of the activated carbon, while clean air is blown back into the room. The activated carbon filter needs to be replaced regularly (usually every 6-12 months, depending on the pollution level) to prevent it from becoming saturated and ineffective.

[0058] 3) Collaborative purification

[0059] In synergy with a negative ion generator: negative ions cause particulate matter to become charged and settle, while activated carbon targets gaseous pollutants, achieving comprehensive removal of both particulate matter and gaseous pollutants.

[0060] The function of UV lamp bundle 44:

[0061] When the air purification module is activated, polluted air is drawn in by the fan. The air first passes through a pre-filter (removing large dust particles), then flows through an activated carbon layer (adsorbing and enriching pollutants). Next, the pollutant-rich air is subjected to ultraviolet light, where pollutants are efficiently decomposed. The purified air is then returned indoors, working in conjunction with a negative ion generator: negative ions cause airborne particles to settle, while activated carbon targets gaseous and microbial pollutants, achieving comprehensive purification.

[0062] The function of negative ion generator 45:

[0063] Negative ion generators produce a large number of negative air ions (mainly negatively charged oxygen ions O2⁻) by ionizing air with high voltage. These negative ions function in the following ways:

[0064] 1) It has a significant agglomeration and sedimentation effect on PM2.5, dust, pollen, bacterial carriers, etc., and is especially good at handling ultrafine particles that are difficult to capture by traditional filters.

[0065] 2) Negative ions can cause an imbalance in the surface charge of bacteria, viruses and other microorganisms, inhibiting their activity. In some high-concentration negative ion environments, their cell structure can be directly destroyed.

[0066] 3) In synergy with activated carbon, it makes some organic gas molecules easier to be adsorbed or decomposed through charge interaction;

[0067] 4) It can achieve large-scale air purification without the need for a fan to force circulation, operates quietly, and brings a "forest after rain" feeling;

[0068] 5) The negative ion generator can be started independently, silently releasing negative ions into the indoor space. More often, it works in conjunction with an air purifying fan. The fan drives airflow, and the ions released by the negative ion generator diffuse throughout the room with the airflow, achieving faster and more even purification.

[0069] Example 3: Based on the above examples, the present invention further discloses the internal structure of a water purification device, such as... Figure 5 , 6 As shown, the water purification device 24 includes a barrel-shaped outer shell 241. The two ends of the barrel-shaped outer shell 241 are respectively provided with an inlet 242 and an outlet 243. Both the inlet 242 and the outlet 243 are provided with threads, which are connected to external pipes through the threads. After regular operation, the water purification device can be removed for maintenance and replacement.

[0070] The barrel-shaped outer shell 241 contains water purification filter media, which includes a silicon phosphate crystal anti-scaling agent 244, a magnetic filter media 245, and activated carbon particles 246. Each pair of adjacent filter media is separated by a plastic grid. The silicon phosphate crystal anti-scaling agent accounts for 50%, the magnetic filter media accounts for 30%, and the activated carbon particles account for 20%. The various water purification filter media work together.

[0071] The function of silicon phosphate scale inhibitor 244:

[0072] 1) Scale inhibition (scale prevention)

[0073] The main components of phosphate crystals are polyphosphates and silicates. When they slowly dissolve in water, they release polyphosphate ions. These polyphosphate ions can chelate with scale-forming cations such as calcium and magnesium in the water to form a soluble complex. They can adsorb onto the surface of microcrystal nuclei such as calcium carbonate that are forming, interfering with their normal crystal growth, causing the crystal structure to become distorted, loose, and soft, unable to adhere firmly to the pipe wall or heat exchange surface.

[0074] Hard scale is transformed into soft scale or suspended matter that is easily washed away by water flow, thereby preventing the formation of hard scale on the inner walls of pipes, pumps, heat exchangers and fan coil units.

[0075] 2) Corrosion Inhibitor (Anti-corrosion)

[0076] Dissolved polyphosphates can promote the formation of a thin and dense "passivation protective film" (mainly composed of γ-Fe2O3 and calcium iron polyphosphate) on the inner surface of metals (such as steel pipes, copper pipes, and cast iron pump bodies). This protective film effectively prevents dissolved oxygen and corrosive ions in the water from directly contacting the metal substrate, thereby significantly slowing down the corrosion (rusting) rate of the system. If the film is locally damaged, the polyphosphates in the water will preferentially reform at the exposed metal points, playing a dynamic repair role.

[0077] The function of magnetic filter media 245:

[0078] Its core principle is to use a high-intensity magnetic field to change the physicochemical properties of the water flowing through it, thereby preventing and removing scale, inhibiting corrosion, and purifying suspended solids. It requires no power and does not require the addition of chemical agents, making it an environmentally friendly treatment method.

[0079] Magnetic filter media acts as a "physical pretreatment and purification enhancer." Through the cleaning energy of a magnetic field, it fundamentally alters the scaling characteristics of water and assists in corrosion prevention and flocculation. When combined with chemical methods (silicon phosphate crystals) and adsorption methods (resins) in a composite water purification device, it constructs a multi-layered, multi-mechanism synergistic protection network. This allows for the maximum protection of the long-term cleanliness, efficiency, and stable operation of the closed-loop water system in a more economical and environmentally friendly manner, making it one of the key technological supports for achieving the system's goals of "no disassembly or cleaning required, minimal maintenance, and long lifespan."

[0080] The function of activated carbon granules 246:

[0081] It adsorbs trace amounts of dissolved organic matter, additive decomposition products, or odors from circulating or makeup water. If the makeup water is tap water, it can effectively remove residual chlorine and prevent stress corrosion of metal pipes (especially stainless steel) caused by chloride ions. It is part of a deep purification unit and often works in conjunction with other technologies.

[0082] Example 4: A method for adapting to this integrated high-efficiency heat exchange system, which achieves adaptive energy-saving operation and safety protection of the system through coordinated control of outdoor temperature prediction, differential pressure feedback, air quality monitoring and temperature protection.

[0083] Specifically, it includes the following methods:

[0084] 1. End-point group control

[0085] The system performs gradient start-stop control on the terminal equipment based on outdoor ambient temperature parameters to dynamically match changes in building load.

[0086] When the outdoor temperature sensor detects that the ambient temperature is lower than or equal to -10℃, the control module drives all fan coil unit terminals to turn on.

[0087] When the ambient temperature reaches 5℃, the control module shuts down 50% of the fan coil unit terminals.

[0088] When the ambient temperature is detected to be 13°C or higher, the control module shuts down all fan coil unit terminals.

[0089] As the number of terminals opened decreases, the system's circulating water flow requirement decreases accordingly.

[0090] 2. Adaptive Variable Flow Control

[0091] To achieve precise matching of pump energy consumption, the system adopts a flow adaptive adjustment method based on differential pressure feedback:

[0092] A resistance sensor is installed on the inlet or outlet pipeline of the circulating pump to monitor changes in system resistance in real time.

[0093] When the start / stop status of the terminal equipment changes, causing a change in the system flow demand, the resistance sensor will feed back the detected differential pressure signal to the pump speed controller; the pump speed controller will automatically adjust the pump operating status to one of the three speed levels of high, medium, and low according to a preset program.

[0094] Through the above closed-loop control, the system water flow rate is accurately matched with the real-time load at the terminal, thereby achieving energy-saving operation of the water pump.

[0095] 3. Intelligent air quality purification and control

[0096] The system is equipped with an air quality monitoring and purification module, including the following control methods:

[0097] The online controller integrates an air quality sensor for real-time monitoring of indoor PM2.5 and TVOC concentration parameters.

[0098] When the air quality parameters detected exceed the preset threshold, the sensor sends a signal to the wired controller, which automatically starts the fan of the air purifier.

[0099] Users can manually control the start and stop of the fan through the wired controller interface, realizing human-machine interaction.

[0100] 4. Water temperature setting and safety protection mechanism

[0101] The system sets the corresponding outlet water temperature according to different operating conditions and terminal types, and is equipped with protection against misoperation.

[0102] Winter heating conditions:

[0103] When using underfloor heating terminals, the outlet water temperature should be set to 30-35℃;

[0104] When using fan coil units as the terminal, the outlet water temperature should be set to 40-45℃;

[0105] Summer cooling conditions:

[0106] When using underfloor heating terminals for cooling, the outlet water temperature should be set to 15–18℃.

[0107] When using fan coil units as the terminal, the outlet water temperature should be set to 7-10℃;

[0108] Once the unit reaches the set temperature and enters a balanced state, if the deviation between the manually set temperature value and the system's recommended temperature value exceeds 5°C, the system will trigger an alarm and execute a shutdown protection to prevent equipment malfunction.

[0109] 5. Functions of the intelligent monitoring platform

[0110] The system provides the following monitoring functions through the IoT smart control platform:

[0111] Real-time display of equipment fault alarm information;

[0112] Visualize the on / off status of each terminal fan coil unit;

[0113] Calculate and display the total power consumption of the system;

[0114] Real-time monitoring of the inlet and outlet water temperatures of the terminal equipment;

[0115] Monitor the start / stop status and operating speed of the circulating water pump.
