[0002] Heating, Ventilation, and Air Conditioning (HVAC) system is a technology widely used in building environments to provide a comfortable indoor environment. Its basic functions include regulating air temperature, humidity, air flow and air quality. HVAC system plays a vital role in commercial buildings, residences, industrial facilities and other places. By providing suitable environmental conditions, it improves living and working efficiency. The main uses of HVAC system include: in cold seasons or regions, to increase indoor temperature by heating air or water; to ensure the exchange of indoor and outdoor air, provide fresh air, and exhaust indoor pollutants; in hot weather, to reduce indoor temperature by circulating refrigerants; to improve indoor air quality by filtering, dehumidifying or humidifying.

[0003] The structure of an HVAC system usually includes multiple parts, and heat exchange equipment is one of the core components. The main function of heat exchange equipment is to exchange heat to achieve the purpose of heating or cooling. Heat exchange equipment has been widely used in HVAC systems, but there are still some shortcomings. Many traditional heat exchange equipment can only use a single heat source, such as gas or electricity, which limits the flexibility and sustainability of the system and cannot make full use of renewable energy. During the heat transfer process, the design of traditional heat exchange equipment may lead to large heat losses, thereby reducing the overall energy efficiency of the system, which not only increases operating costs, but also has an adverse impact on the environment. Summary of the invention

[0004] In order to solve the problems of single heat source and high heat loss, the present invention provides an environmentally friendly and energy-saving heat exchange device for HVAC.

[0005] The environmentally friendly and energy-saving heat exchange device of a heating, ventilation and air conditioning system provided by the present invention adopts the following technical solution: An environmentally friendly and energy-saving heat exchange device for heating, ventilation and air conditioning, comprising: The heat source input assembly includes multiple groups and is used to connect multiple heat sources to the heat exchange device for heat exchange; The graded heat exchange component is connected to the heat source input component through an input pipeline and performs heat exchange between the heat source input by the heat source input component and the air, and performs graded heat exchange with the air according to the temperature of the multiple heat sources input by the heat source input component; The heat-insulating package component is wrapped around the outside of the graded heat exchange component to prevent the graded heat exchange component from exchanging heat with the outside air; The waste heat recovery component supplements the energy input by the heat source input component by recovering the heat dissipated from buildings or equipment; The control and monitoring component is used to monitor the operating parameters of the heat source input component and the hierarchical heat exchange component, and further calculate and analyze the operating efficiency.

[0006] The heat source input component can be connected to various heat sources, including renewable energy and waste heat recovery, which improves the flexibility and energy-saving effect of the system, reduces the dependence on a single energy source, lowers the operating cost. The hierarchical heat exchange component conducts hierarchical heat exchange according to the temperature of the heat source, optimizing the heat transfer process, maximizing the utilization of thermal energy, and improving the heat exchange efficiency. The heat insulation and wrapping component effectively blocks the heat exchange between the hierarchical heat exchange component and the external air, reduces heat loss, and further improves the energy efficiency of the system. The waste heat recovery component can recover the waste heat dissipated from buildings or equipment, supplement the energy of the heat source input component, reduce energy waste, and achieve a higher energy-saving effect. The control and monitoring component monitors the working state of the system in real time, calculates and analyzes the operating efficiency, and optimizes the operation of each component through an intelligent control system to ensure that the system always operates in the best state, improving the overall efficiency and reliability.

[0007] Furthermore, the heat source input component includes a heat source pump, a heat source circulation pipe, and an electric heating pipe. The heat source pump is installed on the heat source circulation pipe and pumps the heat source in the heat source circulation pipe to move. The heat source circulation pipe is externally connected to a heat source supply and connected to the hierarchical heat exchange component. The electric heating pipe is externally connected to a power source and connected to the hierarchical heat exchange component.

[0008] Through the combination of the heat source pump and the heat source circulation pipe, the system can access and effectively utilize various external heat sources. Whether it is solar energy, geothermal energy, or other renewable energy, it can be efficiently transmitted to the system through the circulation pipeline, reducing the dependence on a single energy source. The electric heating pipe provides an additional heat supplement function. When the external heat source is insufficient or additional heat is required under specific circumstances, the electric heating pipe can be quickly started to ensure the continuous heating capacity and reliability of the system. The heat source pump ensures the rapid flow and uniform distribution of the heat source, accelerates the heat transfer speed, and reduces energy waste at the same time. The design of the entire system improves the energy utilization efficiency. Through the flexible input of multiple heat sources and the auxiliary function of the electric heating pipe, the system can maintain efficient and stable operation under different environments and requirements, with stronger adaptability. Since the system can make full use of renewable energy and waste heat recovery, it reduces the dependence on and consumption of traditional energy sources, significantly reducing the operating cost and environmental load.

[0009] Further, the rotating main shaft of the heat source pump is connected to the heat source motor and rotates to pump under the drive of the heat source motor. A heat source filter valve is installed at one end of the inlet of the heat source pump, and a heat source flow valve is installed at one end of the outlet of the heat source pump. The end of the heat source circulation pipe is connected to the hierarchical heat exchange component through a heat source pipe joint. A heat source ball valve is installed on the heat source circulation pipe. The end of the electric heating pipe is provided with an electric connector and is externally connected to a power source through the electric connector. The electric heating pipe is controlled and connected to a temperature controller.

[0010] The heat source filter valve ensures the cleanliness of the heat source entering the system, avoids system blockage and damage, extends the service life of the equipment, improves the heat exchange efficiency and system stability. The installation of the heat source ball valve makes the flow and switching of the heat source more flexible, facilitates the maintenance and operation of the system, and improves the reliability of the system. The electric heating pipe provides the necessary auxiliary heating function to ensure that the system can still operate normally when the external heat source is insufficient. The use of the temperature controller enables precise control of the heating temperature of the electric heating pipe, avoids overheating or overcooling, and further improves the stability and safety of the system. By optimizing the design of the heat source input component, the system can operate efficiently under various heat source conditions, has stronger adaptability. The design of the entire system improves the energy utilization efficiency, reduces the operating cost, and has significant economic and environmental benefits.

[0011] Further, the hierarchical heat exchange component includes a heat exchange blower, a heat exchange circulation pipe, and a baffle. The heat exchange blower is connected to the heat exchange circulation pipe and pumps air into the heat exchange circulation pipe. The heat exchange circulation pipe contacts and exchanges heat with the heat source input component, and baffles are provided at the contacting part between the heat exchange circulation pipe and the heat source input component.

[0012] The heat exchange blower ensures the continuous flow and renewal of air, enabling air to efficiently enter the heat exchange circulation pipe for heat exchange. The setting of the baffle disturbs the air flow, increases the contact time between the air and the heat source, and thus significantly improves the heat exchange efficiency. The heat exchange blower provides stable air flow, avoids air flow stagnation and uneven distribution during the heat exchange process, and ensures the heat exchange efficiency and stability of the entire system. Through the optimization of air flow, the energy consumption of the system is further reduced, and the overall operating efficiency is improved. The overall structural design reduces heat loss, improves the utilization rate of heat energy, and reduces the operating cost.

[0013] Furthermore, the rotating main shaft of the heat exchange blower is connected to a heat exchange motor and rotates to blow air under the drive of the heat exchange motor. An air filter is installed at one end of the air inlet of the heat exchange blower. The starting end of the heat exchange of the heat exchange circulation pipe is connected to an air collector, and the ending end of the heat exchange of the heat exchange circulation pipe is connected to a shunt. An air butterfly valve is installed on the heat exchange circulation pipe. The baffle is swingably installed in the guiding groove. The guiding groove is externally connected to the heat exchange circulation pipe. One side of the baffle where it swings is connected to a pull rod. The pull rod is threadedly connected to an adjusting bolt. The pull rod drives the baffle to swing under the adjustment and control of the adjusting bolt.

[0014] The air filter ensures the cleanliness of the air entering the system, reduces the damage of impurities to the system, and extends the service life of the equipment. The air butterfly valve provides precise air flow control, enabling the system to operate efficiently under different working conditions. The use of the air collector and the shunt ensures uniform air flow when entering and leaving the heat exchange circulation pipe, reducing air flow stagnation and uneven distribution. The design of the baffle increases the residence time of air in the heat exchange circulation pipe by disturbing the air flow, improving the heat exchange efficiency between the air and the heat source. By controlling the swing of the baffle through the pull rod and the adjusting bolt, the system can flexibly adjust the degree of air flow disturbance according to actual needs to adapt to different heat exchange requirements.

[0015] Furthermore, the heat preservation wrapping assembly includes a shell layer, a heat preservation layer, and a protection layer. The shell layer is used to wrap and support the hierarchical heat exchange assembly. The heat preservation layer is wrapped outside the shell layer, and the protection layer is wrapped outside the shell layer and the heat preservation layer.

[0016] The heat preservation layer effectively reduces the heat dissipation to the outside world, maintains the temperature inside the heat exchange assembly, thereby improving the energy utilization efficiency. The optimized heat retention function ensures that the system can operate in a more efficient state, reducing energy consumption. The shell layer provides strong physical protection for the system, preventing external impacts and mechanical damages, and extending the equipment life. The protection layer increases the resistance to environmental factors, reduces the risk of corrosion and wear, improves the safety and reliability of the system. By providing a stable working environment, the system can better cope with load fluctuations and external environmental changes.

[0017] Furthermore, a sound insulation sticker is pasted on the inner surface of the shell layer. A water collecting trough is arranged at the bottom of the shell layer and drained through an externally connected drain pipe. An inspection hole is opened on the shell layer and an inspection cover is installed at the inspection hole. The heat preservation layer is divided into two layers with a vacuum interlayer in the middle. An anti-freezing sticker is pasted on the outer surface of the heat preservation layer. An anti-rust coating is applied on the outer side of the protection layer.

[0018] The sound insulation installation effectively reduces the noise output during equipment operation, improves the environmental comfort, and is suitable for places with strict noise requirements. The water collecting tank and drainage system ensure liquid management during equipment operation, preventing equipment damage and safety hazards caused by water accumulation. The design of the inspection hole and inspection cover facilitates quick access to the interior of the equipment for inspection and maintenance. The double-layer insulation design and vacuum interlayer significantly improve the heat insulation efficiency, reduce energy loss, and enhance the thermal efficiency of the equipment. The anti-freezing installation ensures that the equipment will not be damaged due to freezing under cold conditions, expanding the applicable range of the equipment. The rust-proof coating provides long-term protection for the equipment, reduces the risk of corrosion and physical damage, and extends the service life of the equipment.

[0019] Furthermore, the waste heat recovery component includes a preheating box and a recovery pipeline. The preheating box is wrapped around the heat exchange starting end of the hierarchical heat exchange component, and the recovery pipeline is connected to the inside of the preheating box and externally connected to the building interior.

[0020] Through waste heat recovery, the heat that might otherwise be wasted is reused, significantly improving the overall energy utilization rate, reducing the energy consumption of the system. By using waste heat for preheating or heating, the demand for additional energy is reduced, thereby lowering the operating cost of the building. The effective utilization of waste heat resources reduces the dependence on fossil fuels, lowers carbon emissions and environmental load. By optimizing heat energy management, the wear and faults caused by overheating or heat loss of the equipment are reduced, and the service life of the equipment is extended.

[0021] Furthermore, a preheating coil is arranged inside the preheating box. The preheating coil is connected to the heat exchange end of the heat source circulation pipe of the heat source input component and guides the heat-exchanged heat source to preheat the air that is about to enter the hierarchical heat exchange component through the preheating box. A low heat source pipe is arranged inside the preheating box, and the low heat source pipe is externally connected to a low heat source supply device. A filter purifier is installed on the recovery pipeline. The recovery pipeline is connected to a recovery blower and drives the extraction of the circulating air in the building through the recovery blower. The rotating main shaft of the recovery blower is connected to a recovery motor.

[0022] Through the effective function of the preheating coil, the efficient transfer and utilization of heat energy are ensured, and the thermal efficiency of the entire system is improved. The introduction of the low heat source pipe provides additional heat source support for the system at low temperatures, ensuring the stable operation of the system under various environmental conditions. The use of the filter purifier improves the quality of the circulating air, providing cleaner and healthier air for the indoor environment. The efficient operation of the recovery blower ensures the rapid circulation of air and the effective distribution of heat, improving the response speed and efficiency of the system. Through efficient waste heat recovery and air management, the demand for external energy is significantly reduced, and the energy consumption and operating cost of the system are decreased.

[0023] Further, the control and monitoring component includes a temperature monitoring module, a flow rate monitoring module, and a pressure monitoring module. The temperature monitoring module, the flow rate monitoring module, and the pressure monitoring module are distributed in the heat source input component and the hierarchical heat exchange component, and are respectively used to monitor temperature data, flow rate data, and pressure data. The temperature monitoring module includes a temperature sensor, a thermometer, and a temperature alarm. The temperature sensor is used to monitor temperature data and convert it into electrical signal data. The thermometer is used to monitor and display the internal temperature of the component. The temperature alarm is controlled and triggered to connect to the temperature sensor. The flow rate monitoring module includes a flow rate sensor and a flow meter. The flow rate sensor is used to monitor flow rate data and convert it into electrical signal data. The flow meter is used to count and display the internal flow rate of the component.

[0024] By monitoring temperature, flow rate, and pressure in real time, abnormal conditions can be detected in a timely manner, potential faults or accidents can be prevented, and the safe operation of the system can be ensured. Real-time data feedback enables operators to adjust the system according to the actual situation, improving the overall operation efficiency and performance. By preventing adverse conditions such as overheating and overpressure, equipment wear and damage are reduced, significantly extending the service life of the system. Through the monitoring and alarm system, problems can be identified and solved in the early stage, reducing the maintenance cost caused by sudden failures. Precise data monitoring helps optimize operation strategies, improve energy utilization efficiency, and reduce operation costs.

[0025] In summary, the present invention has the following beneficial technical effects: 1. It supports the access and utilization of multiple heat sources.
