Description

Technical Field

[0001] This invention belongs to the technical field of cross-technology of air conditioning and small power generation equipment, specifically relating to a household absorption air conditioner with dual functions of cooling, heating and power generation, and more particularly to an integrated household air conditioner power generation device based on a graphite titanium plate heat exchanger and a calcium chloride absorbent-ammonia water refrigerant working fluid pair. Background Technology

[0002] Traditional household air conditioners mostly use compressor-based refrigeration. The compressor is the main energy-consuming component and generates heat and noise during operation. Concentrated use in summer can also place a huge load on the power grid. While traditional absorption refrigeration technology eliminates the need for a compressor, it suffers from several drawbacks: heat exchange components often use copper tubes with a heat transfer coefficient of only about 2000 W / (m²・K), resulting in low heat exchange efficiency and significant heat loss; condensation and absorber cooling rely on a water-circulating cooling tower, leading to a cumbersome process, high equipment costs, and large water consumption; the working fluid is often lithium bromide and water, but water's freezing point is 0°C, and physical changes occur around 4°C, resulting in a high dew point and limited cooling performance; furthermore, traditional absorption air conditioners only provide cooling or heating functions and lack a power generation module, making them unsuitable for independent use in remote, unpowered areas such as beaches, bays, and islands, thus limiting their applicability.

[0003] In addition, traditional absorption air conditioners do not integrate a power generation module in their structural design, have an unreasonable layout of heat exchange components, do not have a vacuum port to optimize and reduce vaporization temperature, and are mostly made of ordinary carbon steel with poor corrosion resistance, making them unsuitable for complex outdoor environments. The pump layout and throttling structure design of the circulation system are also imperfect, resulting in low heat exchange efficiency and high energy consumption, which cannot meet the needs of small-scale and multi-functional household applications.

[0004] To address the aforementioned issues and align with the national sustainable development strategy for new energy, there is an urgent need to develop a household air conditioning unit that integrates energy-saving cooling, heating, and self-generated power generation, achieving technological upgrades such as improved heat exchange efficiency, simplified heat dissipation methods, diversified functions, and optimized structure. Summary of the Invention

[0005] The purpose of this invention is to provide a household absorption air conditioner that can generate electricity, eliminating the need for a traditional compressor and integrating power generation. It optimizes the heat exchange components, working fluid pair, heat dissipation system and structural layout, and designs a switchable circulation system to achieve multi-mode operation of cooling, heating and separate power generation. This solves the problems of high energy consumption, high noise, single function and poor applicability in remote areas of traditional air conditioners. At the same time, it improves heat exchange efficiency, reduces water consumption and equipment size, optimizes structural layout, and improves equipment reliability and environmental adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A household absorption air conditioner with both power generation and cooling functions includes a mode control module, a power generation module, an absorption cooling and heating module, a circulation system module, and a heat dissipation module. The mode control module is a circuit board, which controls the switching of cooling, heating and separate power generation modes by controlling the power supply of each component; the power generation module is located at the original compressor installation position of the external condenser (2) to supply power to the electrical components of the equipment; the absorption cooling and heating module eliminates the compressor and includes an external evaporator (1), an external condenser (2), an internal plate evaporator (3), a plate absorber (4), an electric heating generator (5), a plate condenser (6), and a graphite plate heat exchanger (10). Each plate heat exchanger is made of graphite titanium plate, and the outer shell of the machine body is made of titanium material; the circulation system module is equipped with an external liquid pump (7, 8) and a solution pump (9). The working fluid is calcium chloride as absorbent and ammonia as refrigerant. The fluid in the condenser and absorber is in a gas-liquid phase change state; the heat dissipation module is an air-cooled structure, which is adapted to the gas-liquid phase change heat dissipation requirements of the absorption cooling and heating module. Its cyclic drive is replaced by an electric heating generator instead of a traditional compressor. This thermal energy drive in a vacuum state can separate the absorbent and refrigerant at temperatures above 60°C, reducing the vaporization temperature by nearly 40°C. The machine operates in a vacuum state, which aims to reduce the vaporization temperature of the solution. The vacuum degree is drawn by an external micro vacuum pump (11), and the vacuum pump is powered by a generator. The circuit design is fully automatic.

[0007] Furthermore, the power generation module includes a 3-6KW direct-drive permanent magnet micro wind generator, a transmission, and an electronic frequency converter. The transmission is a planetary transmission or a worm gear transmission. The generator is adapted to a 700 rpm operating speed and can output 220V single-phase or 380V three-phase voltage. The electronic frequency converter is used to ensure the power supply frequency characteristics of the power generation module.

[0008] Furthermore, the heat exchangers made of the graphite titanium plates can achieve a heat transfer coefficient of 6000W / (m2・K) to 7000W / (m2・K) under vacuum conditions, with a plate thickness of about 0.5mm, a plate spacing of 2 to 5mm, a compactness of up to 1500m2 / m3, and a metal consumption of only 16Kg / m3.

[0009] Furthermore, the electric heating generator (5) is a plate heater, and its power is provided by the power generation module. The graphite plate heat exchanger (10) is located in the circulation path of the system to recover heat energy and reduce system heat loss.

[0010] Furthermore, the external liquid pumps (7, 8) can switch the direction of fluid circulation by reversing the flow, and the solution pump (9) drives the calcium chloride-ammonia solution to complete the concentration-dilution cycle in the system, thereby realizing the vaporization separation and liquefaction mixing of the working fluid pair.

[0011] Furthermore, the external evaporator (1) and the plate absorber (4) can switch functions by reversing the external liquid pump (7, 8) or switching the valve. The external condenser (2) and the internal plate evaporator (3) can switch functions according to the season, adapting to the heat pump principle to complete the switching between cooling and heating modes.

[0012] Furthermore, the air-cooled heat dissipation module includes a fan, a graphene evaporative condenser, and a graphene evaporative absorber. The heat dissipation carrier is ethanol or acetone, and the applicable heat dissipation temperature range is 0-130℃. Moreover, the latent heat is greater than that of water and Freon. A small household water pump is used to realize the circulation of the heat dissipation carrier.

[0013] Furthermore, in the standalone power generation mode, the circuit board of the mode control module controls the disconnection of the power supply of the electric heating generator (5), solution pump (9), external evaporator (1), plate condenser (6), and plate absorber (4), and only keeps the condensing fan of the external condenser (2) running, which drives the power generation module to generate electricity.

[0014] Furthermore, the titanium material casing is combined with the graphite titanium plate heat exchanger to improve the equipment's corrosion resistance and structural strength, making it suitable for use with calcium chloride-ammonia water as the working fluid.

[0015] Furthermore, the power generation module is synchronously driven by the condenser fan of the external condenser (2), and the power consumption of the solution pump (9), external liquid pump (7, 8) and electric heating generator (5) is provided by the power generation module itself, without the need for external power grid connection; the vacuum state in the unit is intended to reduce the vaporization temperature of the solution.

[0016] Compared with the prior art, the household absorption air conditioner generator of the present invention has the following significant advantages: 1. Energy saving and low noise: The compressor is eliminated, which greatly reduces power consumption and eliminates the heat and noise generated by the compressor. The power generation module provides power to the equipment independently without the need for external power grid connection, which is in line with the new energy strategy and will not increase the power grid load during summer use.

[0017] 2. High heat exchange efficiency and miniaturized equipment: The heat exchange coefficient of the graphite titanium plate composite plate heat exchanger is more than 3 times that of the traditional copper tube, the heat exchange area is only 1 / 3 to 1 / 4 of that of the copper tube, the volume under the same heat load is 1 / 3 of that of the shell and tube heat exchanger, the weight is 1 / 2 to 1 / 5 lighter, the metal material consumption is low, the equipment is miniaturized, and it is suitable for various household scenarios; the external condenser (2) adopts a graphite fin heat exchanger to further improve the heat dissipation efficiency.

[0018] 3. Structural optimization and performance improvement: The plate condenser (6) is equipped with a vacuum port, which effectively reduces the separation and vaporization temperature of the internal refrigerant and absorbent, and improves the condensation efficiency and cooling effect; the graphite plate heat exchanger (10) serves as an intermediate heat exchanger, which recovers heat energy significantly, reduces heat loss, and improves system energy efficiency; the outer shell of the machine is made of titanium material, which is corrosion resistant, lightweight, and suitable for complex outdoor environments.

[0019] 4. High heat dissipation efficiency and low water consumption: the fan air cooling replaces the water cooling tower, which simplifies the process and reduces equipment costs; the ethanol / acetone heat dissipation carrier has a wide temperature range and greater latent heat; the plate condenser (6) and plate absorber (4) use gas-liquid phase change heat dissipation, the theoretical water dissipation is 1% of the traditional water cooling, the actual water consumption is only 5% to 10%, and there is no splashing, sewage discharge and water replacement loss, the overall energy saving of the condenser is 20% to 40%.

[0020] 5. Multifunctional and widely applicable: It can freely switch between three modes: cooling, heating, and standalone power generation. It can be used in both winter and summer. The standalone power generation mode can be adapted to remote areas without electricity, such as beaches, bays, and islands, to meet the dual needs of household air conditioning and electricity. It can be used alone or in combination.

[0021] 6. Improved refrigeration stability: The working fluid of calcium chloride and ammonia water replaces the traditional lithium bromide and water, resulting in a lower dew point temperature. This avoids the physical changes of water at around 4°C affecting the refrigeration effect and improves the stability of equipment operation. The gas-liquid two-phase flow design and throttling structure optimization further improve circulation efficiency. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the overall structure of a household absorption air conditioner generator that can be used for both heating and power generation according to the present invention. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] This invention proposes a household absorption air conditioner / generator dual-purpose unit, the structure of which corresponds exactly to the reference numerals shown in the attached drawings. It includes a mode control module, a power generation module, an absorption cooling / heating module, a circulation system module, and a heat dissipation module. These modules work together to achieve multi-mode switching operation. Specific technical features are as follows: Mode control module: The circuit board is used as the core control component. By controlling the on and off of the power supply of the electric heating generator (5), the power supply of the solution pump (9), the power supply of the external evaporator (1), the power supply of the external condenser (2) and the power supply of the plate absorber (4) circulation pump (external liquid pump 7, 8), the equipment can switch between three modes: cooling, heating and independent power generation. In the independent power generation mode, only the operation of the outdoor condenser fan and the power generation module is retained.

[0025] The power generation module is located at the original compressor installation position of the external condenser (2), including a 3-6KW direct-drive permanent magnet micro wind generator and a gearbox. The gearbox is a planetary gearbox or a turbine gearbox, located on the side of the external condenser (2), used to adjust the speed and torque of the generator so that the generator meets the operating requirements of 220V single phase / 700 rpm and 380V three phase / 700 rpm. The absorber module provides power to the electric heat generator (5) of the equipment, the solution pump (9), the external liquid pump (7, 8) and other electrical components. The frequency characteristics of the power supply are kept consistent with the power grid by automatic control through the electronic frequency converter. At the same time, it provides working power to the external micro vacuum pump (11).

[0026] Absorption-type refrigeration and heating module: Completely abandons the traditional compressor; the core heat exchange component is a plate heat exchanger made of graphite-titanium composite material. The corresponding reference numerals and functions are as follows: External evaporator (1): installed indoors, used to absorb indoor heat to achieve cooling / absorb outdoor heat to achieve heating; External condenser (2): installed outdoors, it is a graphite fin heat exchanger used to dissipate heat inside the equipment. The generator and frequency converter module are installed in the original compressor position. Inner plate type evaporator (3): Located on the lower left side of the low-pressure circulating chamber inside the equipment, used for heat absorption and cooling of ammonia refrigerant in the outer evaporator; Plate absorber (4): Located on the lower right side of the low-pressure circulating chamber inside the equipment, it is used to absorb the heat of the dilute solution. The working fluid is mixed in the opposite directions of vapor and liquid in winter and summer through the internal pipelines of (4) and (6). Electric heating generator (5): Located on the upper left side of the internal high-pressure circulating chamber, it is an electric heating generator used to heat dilute solutions and achieve the separation of calcium chloride and ammonia; Plate condenser (6): Located on the upper right side of the internal high-pressure circulating chamber, with an air extraction port at the top. A micro vacuum pump (11) is installed outside the unit to extract the vacuum inside the unit, further reducing the separation and vaporization temperature of the refrigerant and absorbent, and improving the condensation efficiency. Graphite plate heat exchanger (10): Located in the middle between the high-pressure chamber and the low-pressure chamber, it is used to recover the heat of the concentrated solution, preheat the dilute solution, and reduce heat loss; the entire shell of the equipment is made of titanium material, which is corrosion resistant, lightweight, and suitable for household and outdoor use scenarios; the working fluid is replaced by calcium chloride (absorbent) and ammonia (refrigerant) instead of the traditional lithium bromide (absorbent) and water (refrigerant), which lowers the dew point temperature and improves the refrigeration stability and refrigeration temperature; the heat transfer coefficient of the plate heat exchanger can reach 6000W / (m²・K) to 7000W / (m²・K) under vacuum conditions, the plate thickness is about 0.5mm, the plate spacing is 2~5mm, the compactness is as high as 1500m² / m³, and the metal consumption is only 16Kg / m³.

[0027] The circulation system module includes an internal circulation system and two internal and external circulation systems, equipped with external liquid pumps (7, 8) and solution pumps (9). Internal circulation system: It consists of an absorbent circulation branch and a refrigerant circulation branch. The unit as a whole maintains a vacuum working state through a micro vacuum pump (11) to reduce the vaporization temperature of the working fluid. The working fluid completes the vaporization separation and liquefaction mixing concentration change in the system. The electric heating generator (5) and plate condenser (6) are in the high-pressure working chamber, while the inner plate evaporator (3) and plate absorber (4) are in the low-pressure working chamber. The solution pump (9) pumps the dilute calcium chloride-ammonia solution at the bottom of the plate absorber (4) into the electric heating generator (5), and after heating, the ammonia refrigerant is separated. The ammonia refrigerant is condensed and liquefied by the plate condenser (6) and then enters the inner plate evaporator (3) to evaporate and absorb heat, thus completing the refrigerant circulation. The concentrated calcium chloride solution is preheated by the graphite plate heat exchanger (10) and then enters the plate absorber (4) to absorb ammonia vapor and complete the absorbent circulation. Two internal and external circulation systems: an endothermic circulation system with ammonia as the working fluid and an exothermic circulation system with methanol / acetone as the working fluid, respectively; external liquid pumps (7, 8) are used for fluid transport in the two internal and external circulation systems respectively. The flow direction of the refrigerant can be switched by reversing or bidirectionally switching the external liquid pumps (7, 8), so that the functions of the external evaporator (1) and external condenser (2), and the internal plate evaporator (3) and plate absorber (4) can be interchanged to meet the heat pump operation requirements for cooling and heating in winter and summer; the fluid in the condenser and absorber is a two-phase gas-liquid system. The fluid vapor-liquid bidirectional adjustment is achieved through the throttling structure. The heat of methanol or acetone vapor liquefying after throttling in the plate condenser (6) is used to heat the external condenser (2) through the fan to reduce the temperature in the lower low-pressure cavity; the refrigerant flowing in the internal and external directions is liquid and enters the internal plate evaporator (3) to conduct heat and cold energy.

[0028] Heat dissipation module: The traditional water circulation cooling tower heat dissipation is replaced by fan-cooled heat dissipation. The heat dissipation carrier is replaced by ethanol or acetone instead of water. The heat dissipation temperature range is 0~130℃, and the latent heat is greater than that of water and Freon. The gas-liquid phase change characteristics of plate condenser (6) and plate absorber (4) are used to achieve efficient heat dissipation. The latent heat of liquid vaporization in the pipeline quickly absorbs the heat energy of condenser and absorber. The external liquid pump (7) completes the circulation and transportation of heat dissipation carrier. The fan of external condenser (2) achieves air cooling heat dissipation.

[0029] The working principle of the household absorption air conditioner generator of the present invention is as follows: Refrigeration mode: Dilute calcium chloride-ammonia solution is pumped from the bottom of the plate absorber (4) into the electric heater (5) via the solution pump (9). The electric heating causes the solution to vaporize at high temperature, and calcium chloride and ammonia working fluid are separated to form ammonia refrigerant. The ammonia vapor enters the plate condenser (6), and the micro vacuum pump (11) continuously draws a vacuum. With the help of the top evacuation port, the vaporization temperature is further reduced. After heat exchange with the low-temperature heat dissipation carrier, it liquefies and enters the inner plate evaporator (3) after the flow rate is adjusted by the throttling structure. It absorbs the heat of the internal circulation. The heat absorbed by the inner plate evaporator (3) is transported to the outer evaporator (1) by the refrigerant driven by the outer liquid pump (8). It absorbs the heat in the room to achieve room cooling. After the plate absorber (4) absorbs the heat of the internal circulation, it is transported to the outer evaporator (1) by the ethanol / The acetone heat dissipation carrier is transported to the external condenser (2), and the heat is dissipated by the fan; the graphite plate heat exchanger (10) recovers the heat of the concentrated solution at the outlet of the electric heating generator (5) and preheats the dilute solution entering the generator, greatly reducing heat loss; during the process, the power generation module continuously supplies power to each electrical component.

[0030] Heating mode: The circuit board issues a reversal command, the external liquid pump (7, 8) reverses, changes the circulation direction of the refrigerant, and makes the functions of the external evaporator (1) and external condenser (2), and the internal plate evaporator (3) and plate absorber (4) interchangeable, adapting to the heat pump operation principle; after the calcium chloride-ammonia solution in the electric heating generator (5) is heated and separated, the refrigerant completes the circulation in the heat exchange components after the interchange, transferring the heat from the outdoor environment to the indoor environment to achieve indoor heating, the power generation module continuously supplies power to each component, and the heat dissipation module dissipates excess heat during normal operation.

[0031] Standalone power generation mode: The circuit board controls the disconnection of the circulating pump power supply of the electric heating generator (5), solution pump (9), external evaporator (1), external condenser (2) and plate absorber (4), and only the outdoor condenser fan runs; the condenser fan rotates and drives the gearbox to work, and after adjusting the speed and torque, it drives the direct-drive permanent magnet micro wind turbine to rotate, outputting 220V single-phase or 380V three-phase voltage to meet the household electricity demand. In this mode, the micro vacuum pump (11) can be started and stopped as needed without affecting the core power generation function.

[0032] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. These embodiments are only used to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0033] This embodiment provides a household absorption air conditioner / generator, the structure of which corresponds exactly to the reference numerals shown in the attached drawings. The parameters and layout of each component are as follows: Power generation module: A 5KW direct-drive permanent magnet micro wind generator is selected, paired with a planetary gearbox, and the generator is adjusted to a 220V single-phase / 700 rpm operating state and installed in the original compressor position of the external condenser (2); Heat exchange components: All plate heat exchangers are made of graphite titanium plate composite material with a plate thickness of 0.5mm and a plate spacing of 3mm. The measured heat transfer coefficient under vacuum conditions is 6500W / (m²・K), the compactness is 1500m² / m³, and the metal consumption is 16Kg / m³. The external condenser (2) is a graphite fin heat exchanger. The plate condenser (6) is equipped with a vacuum port at the top. The external micro vacuum pump (11) is powered by the power generation module to maintain the vacuum working state of the unit. The graphite plate heat exchanger (10) is located between the high pressure chamber and the low pressure chamber for complementary and comprehensive utilization of cold and heat sources. Working fluid pair and carrier: The working fluid pair is calcium chloride (absorbent) and ammonia (refrigerant), the heat dissipation carrier is ethanol, and the cooling agent is ammonia; Pump body and control: The external liquid pump (7, 8) is a small household water pump, the solution pump (9) is a corrosion-resistant solution pump, the micro vacuum pump (11) is a DC micro vacuum pump, the power supply is provided by the generator module, the mode control module is an integrated circuit board with built-in power on / off and pump body reverse control program; Shell Material: The entire shell of the device is made of titanium alloy, which is 2mm thick, corrosion-resistant, lightweight, and suitable for both home and outdoor use.

[0034] Cooling mode operation: The circuit board closes all power supplies, and the solution pump (9) pumps the dilute calcium chloride-ammonia solution at the bottom of the plate absorber (4) into the electric heating generator (5). The electric heating causes the solution to vaporize at high temperature, separating the ammonia refrigerant. The ammonia vapor enters the plate condenser (6), and the micro vacuum pump (11) simultaneously draws a vacuum. With the help of the top evacuation port, the vaporization temperature is further reduced. After heat exchange with the ethanol heat dissipation carrier, it liquefies and enters the inner plate evaporator (3) after the flow rate is adjusted by the throttling structure. It absorbs the heat of the internal circulation. The heat absorbed by the inner plate evaporator (3) is transported to the outer evaporator (1) by the ammonia refrigerant driven by the outer liquid pump (8). It absorbs the heat in the room to achieve continuous room cooling. After the plate absorber (4) absorbs the heat of the internal circulation, it is transported to the outer condenser (2) by the ethanol heat dissipation carrier driven by the outer liquid pump (7). The heat is dissipated by the fan. The graphite plate heat exchanger (10) recovers the heat of the concentrated solution at the outlet of the electric heating generator (5) and preheats the dilute solution entering the generator, reducing heat loss by 30%. The above describes the continuous power supply module for all electrical components, eliminating the need for an external power grid.

[0035] Heating mode operation: The circuit board issues a reversal command, the external liquid pump (7, 8) reverses, changes the circulation direction of the refrigerant and heat dissipation carrier, and makes the functions of the external evaporator (1) and external condenser (2), and the internal plate evaporator (3) and plate absorber (4) interchangeable, adapting to the heat pump operation principle; after the calcium chloride-ammonia solution in the electric heating generator (5) is heated and separated, the ammonia refrigerant completes the circulation in the interchanged heat exchange components, transferring the heat in the outdoor environment to the indoor environment, realizing continuous indoor heating; the power generation module continuously supplies power to the electric heating generator (5), solution pump (9), external liquid pump (7, 8) and other components, and the fan of the external condenser (2) operates normally to dissipate excess heat.

[0036] Standalone power generation mode operation: The circuit board controls the disconnection of the circulating pump power supply of the electric heating generator (5), solution pump (9), external evaporator (1), external condenser (2) and plate absorber (4), and only the outdoor condenser fan runs; the condenser fan rotates and drives the planetary gearbox to work, and after adjusting the speed and torque, it drives the 5KW direct drive permanent magnet micro wind generator to rotate. The generator outputs 220V single-phase voltage, which directly powers household lighting, small household appliances and other equipment to meet the daily power needs of ordinary families. The micro vacuum pump (11) is powered off and stopped in this mode, and does not consume power generation power.

[0037] The household absorption air conditioner generator in this embodiment has no compressor noise during actual operation, and the cooling and heating effects are stable. In the standalone power generation mode, it can meet more than 80% of the electricity demand of ordinary households. The heat exchange efficiency of the graphite titanium plate heat exchanger is 3.25 times that of the traditional copper tube. The equipment volume is reduced by 60% and the weight is reduced by 50% compared with the traditional absorption air conditioner with the same cooling capacity.

The energy saving rate of the evaporative condenser reaches 35%, and the actual water consumption is only 8% of that of the traditional water-cooled absorption air conditioner, which fully meets the energy-saving, environmental protection and practical needs of household scenarios.

[0038] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any further modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
