Description

Technical Field

[0001] The present invention relates to the technical field of heating and ventilation equipment, and in particular to an environmentally friendly and energy-saving heat exchange device for heating, ventilation and air conditioning. Background Art

[0002] Heating, Ventilation, and Air Conditioning (HVAC) systems are a technology widely used in building environments to provide a comfortable indoor environment. Their basic functions include regulating air temperature, humidity, air flow, and air quality. HVAC systems play a vital role in commercial buildings, residences, industrial facilities, and other places. By providing suitable environmental conditions, they improve living and working efficiency. The main uses of HVAC systems include increasing indoor temperatures by heating air or water in cold seasons or regions; ensuring the exchange of indoor and outdoor air, providing fresh air, and exhausting indoor pollutants; lowering indoor temperatures through refrigerant circulation in hot weather; and improving indoor air quality through filtration, dehumidification, or humidification.

[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 loss, 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 present invention provides an environmentally friendly and energy-saving heat exchange device for heating, ventilation and air conditioning, which adopts the following technical solutions:

[0006] An environmentally friendly and energy-saving heat exchange device for heating, ventilation and air conditioning, comprising:

[0007] Heat source input components, including multiple groups and used to connect multiple heat sources to the heat exchange device for heat exchange;

[0008] The graded heat exchange component is connected to the heat source input component through an input pipe and exchanges heat 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;

[0009] The heat-insulating wrapping component is wrapped around the outside of the staged heat exchange component to prevent the staged heat exchange component from exchanging heat with the outside air;

[0010] Waste heat recovery components, which supplement the energy input by heat source input components by recovering the heat emitted by buildings or equipment;

[0011] The control and monitoring component is used to monitor the working parameters of the heat source input component and the staged heat exchange component, and further calculate and analyze the operating efficiency.

[0012] The heat source input component can be connected to a variety of heat sources, including renewable energy and waste heat recovery, which improves the flexibility and energy-saving effect of the system, reduces dependence on a single energy source, and reduces operating costs. The graded heat exchange component performs graded heat exchange according to the temperature of the heat source, optimizes the heat transfer process, maximizes the utilization of heat energy, and improves heat exchange efficiency. The insulation wrap component effectively blocks the heat exchange between the graded 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 emitted by buildings or equipment, supplement the energy of the heat source input component, reduce energy waste, and achieve higher energy-saving effects. The control and monitoring component monitors the working status of the system in real time, calculates and analyzes the operating efficiency, and optimizes the work of each component through the intelligent control system to ensure that the system always operates in the best condition, thereby improving overall efficiency and reliability.

[0013] 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 connected to an external heat source supply and is connected to the staged heat exchange component. The electric heating pipe is connected to an external power supply and is connected to the staged heat exchange component.

[0014] Through the combination of heat source pump and heat source circulation pipe, the system can access and effectively utilize multiple 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 pipe, reducing dependence on a single energy source. The electric heating pipe provides additional heat supplement function. When the external heat source is insufficient or additional heat is needed under certain circumstances, the electric heating pipe can start quickly 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, speeds up the heat transfer speed, and reduces energy waste. The design of the entire system improves energy utilization efficiency. Through the flexible input of multiple heat sources and the auxiliary functions of the electric heating pipe, the system can maintain efficient and stable operation under different environments and needs, and is more adaptable. Since the system can make full use of renewable energy and waste heat recovery, it reduces dependence on and consumption of traditional energy, and significantly reduces operating costs and environmental loads.

[0015] Furthermore, the heat source pump rotates the main shaft to connect to the heat source motor and rotates and pumps under the drive of the heat source motor. A heat source filter valve is installed at one end of the heat source pump inlet, and a heat source flow valve is installed at one end of the heat source pump outlet. The end of the heat source circulation pipe is connected to the graded heat exchange component through a heat source pipe joint. A heat source ball valve is installed on the heat source circulation pipe. An electric connector is provided at the end of the electric heating pipe and an external power supply is connected through the electric connector. The electric heating pipe control is connected to a temperature controller.

[0016] 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, and 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 tube 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 thermostat enables the heating temperature of the electric heating tube to be precisely controlled, avoiding overheating or overcooling, and further improving the stability and safety of the system. By optimizing the design of the heat source input component, the system can operate efficiently under a variety of heat source conditions and is more adaptable. The design of the entire system improves energy utilization efficiency, reduces operating costs, and has significant economic and environmental benefits.

[0017] Furthermore, the graded 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 and the heat source input component are in contact with each other for heat exchange. The contact part between the heat exchange circulation pipe and the heat source input component is provided with a baffle.

[0018] The heat exchange blower ensures the continuous flow and renewal of air, allowing air to efficiently enter the heat exchange circulation tube for heat exchange. The setting of the baffle causes disturbance in the air flow, increasing the contact time between the air and the heat source, thereby significantly improving the heat exchange efficiency. The heat exchange blower provides stable air flow, avoiding air flow stagnation and uneven distribution during the heat exchange process, ensuring 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 thermal energy, and reduces operating costs.

[0019] Furthermore, the heat exchange blower rotates the main shaft to connect to the heat exchange motor and rotates to blow air under the drive of the heat exchange motor. An air filter is installed at the air inlet end of the heat exchange blower, the heat exchange starting end of the heat exchange circulation pipe is connected to an air collector, and the heat exchange end of the heat exchange circulation pipe is connected to a diverter. An air butterfly valve is installed on the heat exchange circulation pipe. The baffle is swingably installed in the guide groove, and the guide groove is externally connected to the heat exchange circulation pipe. A pull rod is connected to one side of the baffle that swings, and the pull rod is threadedly connected to an adjusting bolt. The pull rod drives the baffle to swing under the adjustment control of the adjusting bolt.

[0020] The air filter ensures the cleanliness of the air entering the system, reduces the damage to the system caused by impurities, and extends the service life of the equipment. The air butterfly valve provides precise air flow control, enabling the system to maintain efficient operation under different working conditions. The use of air collectors and diverters ensures that the air flows evenly when entering and leaving the heat exchange circulation tube, reducing air flow stagnation and uneven distribution. The design of the baffle increases the residence time of the air in the heat exchange circulation tube by disturbing the air flow, thereby improving the heat exchange efficiency between the air and the heat source. The swing of the baffle is controlled by the pull rod and adjusting bolt, so that the system can flexibly adjust the disturbance degree of the air flow according to actual needs to adapt to different heat exchange requirements.

[0021] Furthermore, the thermal insulation package component includes a shell layer, an insulation layer and a protective layer. The shell layer is used to wrap and support the graded heat exchange component, the insulation layer is wrapped around the outside of the shell layer, and the protective layer is wrapped around the outside of the shell layer and the insulation layer.

[0022] The insulation layer effectively reduces heat loss to the outside, maintains the temperature inside the heat exchange component, and thus improves energy utilization efficiency. The optimized heat retention function ensures that the system can operate in a more efficient state and reduces energy consumption. The shell layer provides solid physical protection for the system to prevent external impact and mechanical damage, extending the life of the equipment. The protective layer increases resistance to environmental factors, reduces the risk of corrosion and wear, and improves the safety and reliability of the system. By providing a stable working environment, the system can better cope with load fluctuations and changes in the external environment.

[0023] Furthermore, the inner surface of the shell layer is affixed with a sound insulation patch, a water collection tank is provided at the bottom of the shell layer and drainage is carried out through an external drainage pipe, an inspection hole is opened in the shell layer and an inspection cover is installed at the inspection hole, the thermal insulation layer is divided into two layers and a vacuum interlayer is provided in the middle, the outer surface of the thermal insulation layer is affixed with an antifreeze patch, and the outer side of the protective layer is coated with an anti-rust coating.

[0024] The sound insulation patch effectively reduces the noise output of the equipment during operation and improves the comfort of the environment. It is suitable for places with strict requirements on noise. The water collection tank and drainage system ensure the liquid management during the operation of the equipment to prevent 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 insulation efficiency, reduce energy loss, and improve the thermal efficiency of the equipment. The anti-freeze patch ensures that the equipment will not be damaged by freezing in cold conditions, expanding the scope of application of the equipment. The anti-rust coating provides long-term protection for the equipment, reduces the risk of corrosion and physical damage, and extends the service life of the equipment.

[0025] Furthermore, the waste heat recovery component includes a preheating box and a recovery pipe. The preheating box is wrapped around the heat exchange starting end of the graded heat exchange component. The recovery pipe is connected to the inside of the preheating box and externally connected to the inside of the building.

[0026] Through waste heat recovery, heat that might have been wasted is reused, significantly improving overall energy utilization and reducing the system's energy consumption. By using waste heat for preheating or heating, the demand for additional energy is reduced, thereby reducing the operating costs of buildings. Effective use of waste heat resources reduces dependence on fossil fuels, reduces carbon emissions and environmental loads, and by optimizing thermal energy management, reduces equipment wear and failure caused by overheating or heat loss, thereby extending the service life of the equipment.

[0027] Furthermore, a preheating coil is provided in the preheating box, and 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 source after heat exchange to preheat the air that passes through the preheating box and is about to enter the graded heat exchange component. A low heat source pipe is provided in 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 pipe, and the recovery pipe is connected to a recovery blower and driven by the recovery blower to extract circulating air in the building. The recovery blower rotating shaft is connected to the recovery motor.

[0028] The effective function of the preheating coil ensures efficient transfer and utilization of heat energy, and improves the thermal efficiency of the entire system. The introduction of low heat source tubes provides the system with additional heat source support at low temperatures, ensuring stable operation of the system under various environmental conditions. The use of filter purifiers improves the quality of circulating air, providing cleaner and healthier air for the indoor environment. The efficient operation of the recovery blower ensures rapid circulation of air and effective distribution of heat, improving the response speed and efficiency of the system. Through efficient heat recovery and air management, the demand for external energy is significantly reduced, reducing the energy consumption and operating costs of the system.

[0029] Furthermore, 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 graded 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 controls the triggering connection of 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 of the component. The pressure monitoring module includes a pressure sensor, a pressure gauge and a pressure alarm. The pressure sensor is used to monitor pressure data and convert it into electrical signal data. The pressure gauge is used to monitor and display the internal pressure of the component. The pressure alarm controls the triggering connection of the pressure sensor.

[0030] By real-time monitoring of temperature, flow rate and pressure, abnormal conditions can be detected in time, possible failures or accidents can be prevented, and the safe operation of the system can be ensured. Real-time data feedback allows operators to adjust the system according to actual conditions, improve overall operating efficiency and performance, and prevent adverse conditions such as overheating and overpressure, reduce equipment wear and damage, and significantly extend the service life of the system. Through the monitoring and alarm system, problems can be identified and solved at an early stage, reducing maintenance costs caused by sudden failures. Accurate data monitoring helps optimize operating strategies, improve energy utilization efficiency, and reduce operating costs.

[0031] In summary, the present invention has the following beneficial technical effects:

[0032] 1. Support the access and utilization of multiple heat sources. Through the graded heat exchange components, graded heat exchange is carried out according to the temperature of the heat source, maximizing the utilization of heat from different heat sources.
