Description

Technical Field

[0001] This invention relates to the field of intelligent heating technology, and in particular to a dual-heating air conditioner that recovers waste heat and cold. By combining a steam component with a compressor, it overcomes the limitations of traditional air conditioners that are unsuitable for heating in extremely cold weather below -10°C in northern regions. It achieves instant heating as needed, eliminating the need for 24-hour continuous heating as in northern regions. Simultaneously, a heat recovery and storage module is incorporated to recover the heat (both hot and cold) generated by the compressor, achieving a coordinated heating mechanism for winter heating and improving efficiency. Background Technology

[0002] Currently, most mainstream residential and commercial air conditioners on the market, whether split-type or central air conditioning, rely on a vapor compression refrigeration cycle for their basic operation. During summer cooling operation, the high-temperature, high-pressure refrigerant gas discharged from the compressor releases condensation heat into the ambient air in the outdoor unit (condenser). This heat is typically discharged directly into the atmosphere via forced convection by a fan, resulting in significant energy waste. During winter heating operation, the system switches to heat pump mode via a four-way reversing valve, extracting low-temperature heat from the outdoor air, raising its temperature via the compressor, and then releasing it in the indoor unit (evaporator). However, in cold climates, traditional air-source heat pumps suffer from reduced heating efficiency, the need for defrosting due to frost buildup leading to heating interruptions, and slow heating rates, impacting the user experience.

[0003] In addition, to compensate for the slow heating speed of heat pumps in winter, some solutions use electric auxiliary heating (PTC heating) as a supplement. Although the heating speed is fast, electric auxiliary heating has extremely high energy consumption, significantly increasing operating costs, and the air blown out is dry and uncomfortable.

[0004] Therefore, existing technologies lack an integrated air conditioning system that can efficiently recover and store waste heat (cold) generated by the compressor throughout the year, integrate the compressor and steam heat sources in winter to achieve a balance between high efficiency and rapid heating, provide heating even at temperatures above -35°C, and provide instant heating to solve the problem of 24-hour uninterrupted heating in northern regions, while also integrating extended functions such as domestic hot water or drinking water. This is precisely the technical problem that this invention aims to solve. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of the prior art and provide a dual-function air conditioner that recovers waste heat and coolness.

[0006] The present invention adopts the following technical solution: a dual-heating air conditioner with waste cooling and waste heat recovery, comprising a compressor, a first heat exchanger, an electronic expansion valve, a second heat exchanger, a radiator, a radiator fan, and a steam assembly. The second heat exchanger includes a second heat exchanger pipeline one and a second heat exchanger pipeline two. The steam assembly includes a first steam pipeline and a second steam pipeline.

[0007] The second heat exchanger pipeline forms a first pipeline loop with the compressor, the first heat exchanger, and the electronic expansion valve;

[0008] The second heat exchanger pipe is connected to both ends of the radiator pipe to form a second pipe loop;

[0009] The first steam pipe and the second steam pipe are respectively connected to both ends of the pipe of the radiator to form a third pipe loop.

[0010] Furthermore, the air conditioner includes a three-way electric valve, and the second heat exchanger and the steam assembly are respectively connected to the radiator's pipes in parallel through the three-way electric valve. The three-way electric valve is used to control and switch the heat source that supplies the medium to the radiator's pipes, and the heat source is selected from at least one of the second heat exchanger and the steam assembly.

[0011] Furthermore, the first heat exchanger includes a condenser and a condenser fan.

[0012] Furthermore, the first heat exchanger includes a first heat exchanger pipeline and a first heat exchanger pipeline. The first heat exchanger pipeline is connected to the compressor, the electronic expansion valve, and the second heat exchanger pipeline to form a first pipeline loop. The first heat exchanger pipeline is connected to the heat energy recovery and storage module.

[0013] Furthermore, it includes a four-way reversing valve, one end of which is connected in sequence to the compressor and the first heat exchanger, and the other end is connected to the second heat exchanger pipeline.

[0014] Furthermore, the steam assembly includes a water supply unit, which is connected to a storage tank via a pipeline and supplies water to the storage tank. The storage tank is connected in sequence to a solenoid valve and a heater via a pipeline. The heater is connected to the first steam pipeline, and the storage tank is connected to the second steam pipeline. The heater includes a steam generator powered by electricity and / or natural gas and / or a resistance heater and / or an electromagnetic heater, which heats and evaporates liquid water into steam.

[0015] Furthermore, the steam assembly includes a third steam pipeline, one end of which is connected to the second heat exchanger pipeline of the second heat exchanger via a check valve, and the other end is connected to a liquid storage tank.

[0016] Furthermore, the water supply unit includes bottled purified water and / or an external water source with a filter assembly. The water supply unit includes a multi-way valve connected to the bottled purified water and / or the external water source with a filter assembly, and the multi-way valve is also connected to a water outlet. The water outlet includes a normal temperature water path and / or a heated water path. The normal temperature water path is connected to a switch and a normal temperature water outlet, and the heated water path is connected to a water heating module, a switch, and a heated water outlet.

[0017] Furthermore, the number of radiators is at least one, and each radiator is equipped with at least one water storage tank. The water storage tank is connected to the liquid storage tank and is used to collect the condensate generated by the radiator and return it to the liquid storage tank for recycling. At least one fan is provided for each radiator to enhance heat exchange efficiency.

[0018] Furthermore, the heat energy recovery and storage module is an energy storage device containing a phase change material. The phase change material includes one or more combinations of the following materials: paraffin waxes, fatty acids, alcohols, hydrated salts, eutectic molten salts, and organic-organic / organic-inorganic eutectics. The phase change temperature range of the phase change material can be adjusted from -10℃ to 80℃ depending on the application scenario.

[0019] Furthermore, a pump is included between the first heat exchanger and the heat recovery storage module, and / or a pump is included between the second heat exchanger and the radiator.

[0020] Furthermore, the first pipeline circuit also includes a drying filter and / or a gas-liquid separator, the gas-liquid separator being connected to the compressor.

[0021] With the above solution, under the conventional air conditioning technology where the first heat exchanger is a condenser, the introduction of a steam component and a second heat exchanger, connected in parallel to the radiator, can realize either single-cooling application of the compressor or heating application where the compressor and steam component work together.

[0022] By controlling the timing of the steam component's intervention, the compressor's heating and the steam component's heating can be coordinated in winter. The steam component uses a heater to turn water into high-temperature, high-pressure steam, which then flows into the radiator passage, rapidly displacing heat. A fan then blows the hot air into the environment, resulting in high heating efficiency and rapid temperature rise, achieving instant heat. While energy consumption is relatively high, the hot air blown into the environment has higher humidity, making it more tolerable for the skin in winter. The compressor heats up more slowly in winter but consumes less energy. Therefore, a temperature threshold is set: when the ambient temperature is above this threshold, heating is required, activating the compressor to raise the temperature; when the ambient temperature is below this threshold, heating is required, activating the steam component to raise the temperature. A preferred solution is to design this temperature threshold to be 5°C.

[0023] In addition, the introduction of a four-way reversing valve allows the same system to meet both cooling and heating requirements. Moreover, the heating process can still employ a dual heating technology solution that combines steam components and compression, thus achieving multi-purpose functionality.

[0024] Furthermore, when the compressor is working, according to the conventional air conditioning cooling and heating principle, the outdoor unit of the air conditioner (i.e., the first heat exchanger corresponding to this invention) will generate heat or cold. By designing the first heat exchanger as a heat exchanger with two pipes, one of which is connected to the compressor pipe and the other is connected to the heat energy recovery and storage module, the application scope of the heat energy recovery and storage module can be extended. By adopting phase change materials, heat or cold can be recovered and stored, and then reused, such as for refrigeration of insulated bags in cold chain transportation and heating of domestic water.

[0025] The beneficial effects of this invention through the above-described solution include:

[0026] (1) By setting up a heat recovery and heat energy recovery storage module, the heat or cold energy generated during the operation of the compressor in summer or winter can be recovered and stored to achieve secondary energy utilization. Compared with the traditional air conditioner outdoor unit, which directly blows the heat or cold energy generated during the operation of the compressor to the external environment through heat sink and fan, it is more energy-saving and environmentally friendly.

[0027] (2) By setting up a second heat exchanger and a steam component, it is possible to simultaneously exchange cooling energy with the radiator to produce cool air during the summer cooling process and heating energy with the radiator to produce hot air during the winter heating process. The configuration of the steam component works in conjunction with the compressor to meet the dual requirements of low power consumption and rapid heating during the winter heating process, making the control more flexible and the heating faster.

[0028] (3) By setting the filter component of the water making module and the outlet of the bottled water and the normal temperature water and / or heated water in the steam component, the multi-purpose function can be realized. It can meet the functional requirements of air conditioning, as well as the functional requirements of water making and drinking water. Under the premise of the same volume of equipment space occupancy, the solution of the present invention can meet more living functional requirements. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the accompanying drawings.

[0036] 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 and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] like Figure 1As shown, the first embodiment of a dual-function air conditioner with waste heat and cold recovery includes a compressor 1, a four-way reversing valve 2, a first heat exchanger 3, a dryer filter 4, an electronic expansion valve 5, a second heat exchanger 6, and a gas-liquid separator 7 connecting the second heat exchanger 6 and the compressor 1, all connected sequentially via pipelines. The gas-liquid separator 7 has a liquid storage function and is connected to the compressor. The second heat exchanger 6 includes a second heat exchanger pipeline 61 and a second heat exchanger pipeline 62. The air conditioner also includes a radiator 10, a radiator fan 11, and a steam assembly 80, which includes a first steam pipeline 805 and a second steam pipeline 806. One end of the four-way reversing valve 2 is connected sequentially to the compressor 1 and the first heat exchanger 3, and the other end is connected to the second heat exchanger pipeline 61.

[0038] The second heat exchanger pipeline 61 forms a first pipeline loop with the compressor 1, the first heat exchanger 3, and the electronic expansion valve 5.

[0039] The second heat exchanger pipe 62 is connected to both ends of the pipe of the radiator 10 to form a second pipe loop.

[0040] The first steam pipe 805 and the second steam pipe 806 are respectively connected to the two ends of the pipe of the radiator 10 to form a third pipe circuit.

[0041] Further reference Figure 1 As shown, the air conditioner includes a three-way electric valve 12 and a three-way electric valve 12. The second heat exchanger 6 and the steam assembly 80 are connected to the piping of the radiator 10 in parallel via the three-way electric valve 12 and the three-way electric valve 12. The main components controlling and switching the input of the medium into the piping of the radiator 10 via the three-way electric valve 12 and the three-way electric valve 12 are the second heat exchanger 6 and / or the steam assembly 80. A pump 8 is included between the second heat exchanger 6 and the radiator 10, and the pump 8 provides the medium flow power for the third piping loop.

[0042] like Figure 2As shown, the steam assembly 80 includes a third steam pipeline 804, which is connected to the second heat exchanger pipeline 62 of the second heat exchanger 6 via a check valve 14. The steam assembly 80 also includes a water supply unit, comprising bottled purified water 807 and / or an external water source with a filter assembly 808. The water supply unit includes a multi-way valve 809 connected to the bottled purified water 807 and / or the external water source with the filter assembly 808. The water supply unit is connected to a storage tank 801 via a pipeline and supplies water to the storage tank 801. The storage tank 801 is sequentially connected to a solenoid valve 802 and a heater 803 via pipelines. The heater 803 is connected to the first steam pipeline 805, and the storage tank 801 is connected to the second steam pipeline 806. The multi-way valve 809 is also connected to a water outlet, which includes a normal temperature water circuit 811 and / or a heated water circuit 814. The normal temperature water circuit 811 is connected to the normal temperature water circuit switch 812 and the normal temperature water outlet 813. The heated water circuit 814 is connected to the water heating module 815, the heated water circuit switch 812' and the heated water outlet 816.

[0043] The working principle of the steam assembly 80 includes: the heater comprising a steam generator powered by electricity and / or natural gas and / or a resistance heater and / or an electromagnetic heater, which heats and evaporates liquid water into steam. The water supply unit replenishes liquid water to the storage tank 801. After being heated by the heater 803, the liquid water becomes high-temperature, high-pressure steam. The steam enters the radiator pipe through the first steam pipe 805. Under the operation of at least one fan 11, the heat of the steam in at least one radiator is exchanged and transferred to the air, achieving a heating effect. The steam, after heat exchange, becomes liquid water and flows back to the storage tank 801 through the second steam pipe 806. The water supply unit adjusts the water supply according to the water level in the storage tank. Simultaneously, the water supply unit also provides drinking water through the outlet, achieving multiple uses in one unit.

[0044] Combination Figure 1 For example, in one optional solution, the first heat exchanger 3 includes a condenser and a condenser fan. Under this technical combination, combined with the compressor 1, a conventional air conditioning solution is formed. Referring to the cooling and heating principle of air conditioning, it can be understood that when the compressor needs to operate solely for heating, the first heat exchanger 3 simultaneously operates as a condenser. The air conditioner generates heat at the second heat exchanger 6, while simultaneously generating cooling at the first heat exchanger.

[0045] When the steam assembly 80 and the second heat exchanger 6 are introduced and connected to the radiator 10 in parallel, the compressor 1 can be used for refrigeration alone, or the compressor 1 and the steam assembly 80 can be used for heating together. In this state, the check valve 14 is closed and the three-way electric valve 12 and the three-way electric valve 12' are opened. At this time, the heat generated in the circuit where the compressor 1 is located is transferred to the medium in the second heat exchanger pipe 62 through the second heat exchanger 6, and then directly enters the pipe of the radiator 6 through the three-way electric valve 12 and the three-way electric valve 12' for heat exchange.

[0046] One alternative implementation scheme achieves coordinated heating by the compressor and steam components in winter by controlling the activation timing of the steam component 80. The steam component utilizes water, which is converted into high-temperature, high-pressure steam through a heater, and then flows into the radiator passage for rapid heat exchange. A fan then blows the hot air into the environment, resulting in high heating efficiency and rapid temperature rise, achieving instant heat. While energy consumption is relatively high, the hot air blown into the environment has higher humidity, making it more tolerable for skin in winter. The compressor, on the other hand, heats more slowly in winter but consumes less energy. Therefore, a temperature threshold is set: when the ambient temperature is above this threshold, heating is required, activating the compressor to raise the temperature; when the ambient temperature is below this threshold, heating is required, activating the steam component to raise the temperature.

[0047] In a preferred embodiment, the temperature threshold can be set according to the actual usage scenario and energy efficiency requirements, preferably -5℃ to 5℃, and its main usage logic is as follows:

[0048] When the ambient temperature is above 5℃: prioritize starting the compressor for heating, and utilize its high energy efficiency to reduce long-term operating energy consumption.

[0049] When the ambient temperature is between -5℃ and 5℃: users can choose "energy saving mode" (compressor only) or "rapid heating mode" (compressor + steam component working together) according to their needs.

[0050] When the ambient temperature is below -5℃: the steam component is activated first for rapid heating, avoiding energy waste caused by the sudden drop in compressor efficiency at low temperatures, and solving the problem of slow heating in traditional air conditioners during winter.

[0051] The above-mentioned temperature threshold design can adapt to the seasonal changes in most regions. Those skilled in the art will understand that, to better control the air conditioning system based on the principles of this invention, more detailed temperature threshold schemes can be adopted, such as:

[0052] Scene type Recommended threshold Adjust logic Northern cold regions 0℃~5℃ Winter temperatures often drop below -10°C. Increasing the threshold can ensure the rapid start-up of the steam components in low-temperature environments and prevent inefficient operation of the compressor. Southern cold and humid regions 5℃~8℃ Winter temperatures are mostly between 0℃ and 10℃. Appropriately raising the threshold can utilize the humidification properties of the steam components to alleviate the discomfort of a damp and cold environment. Energy-saving priority users -10℃~0℃ Lowering the threshold allows the steam components to be activated only at extremely low temperatures, maximizing the energy-saving benefits of compressor heating. Rapid heating priority users 8℃~10℃ By raising the threshold, the steam unit is activated when the temperature is slightly lower, achieving an "instant hot" user experience.

[0053] Another optional solution is to connect the third steam pipeline 804 to the second heat exchanger pipeline 62 of the second heat exchanger 6 via the check valve 14, and simultaneously connect it to the liquid storage tank 801 of the steam assembly 80. In this state, the heat generated in the first pipeline circuit where the compressor 1 is located can be transferred to the medium in the second heat exchanger pipeline 62 through the second heat exchanger 6. At the same time, the three-way electric valve 12 and the three-way electric valve 12' are closed, so that the medium in the second heat exchanger pipeline 62 does not directly enter the radiator 10 pipeline. Therefore, the medium with heat will directly enter the liquid storage tank 801 through the third steam pipeline 804. After the medium with a certain amount of heat (a certain temperature) enters the liquid storage tank 801, it enters the working cycle of the steam assembly 80. Under the action of the heater 803 in the steam assembly 80, it is further and more efficiently transformed into high-temperature and high-pressure steam, thereby participating more efficiently in outputting heat to the radiator and realizing rapid heating. Therefore, it can be seen that the pipeline system where the compressor 1 is located and the system of the steam assembly 80 are connected in series under this scheme.

[0054] Reference Figure 3 As shown, when the air conditioner is used for cooling, referring to the cooling principle of a traditional compressor air conditioner, the four-way reversing valve 2 introduces the high-temperature, high-pressure refrigerant in the reverse direction into the first heat exchanger 3 to begin circulating in the first pipeline loop, so that the low-temperature medium is exchanged at the second heat exchanger 6 and flows to the radiator 10, thereby blowing out cold air through the fan 11. The principle of refrigerant changes in the air conditioning system during the cooling process will not be elaborated further here.

[0055] With the above solution and the support of the four-way reversing valve 2, it is possible to achieve both cooling and heating in the same system. At the same time, the heating can be selected in single heating or dual heating mode, realizing one machine for multiple uses and multiple functions.

[0056] like Figure 4 and Figure 5 As shown, based on the aforementioned first embodiment, a second embodiment is proposed. The first heat exchanger 3 includes a first heat exchanger pipe 31 and a first heat exchanger pipe 32. The first heat exchanger pipe 31 is connected to the compressor 1, the electronic expansion valve 5, and the second heat exchanger pipe 61, forming a first pipe loop. The first heat exchanger pipe 32 is connected to the heat energy recovery and storage module 9, forming a second pipe loop. A pump 8 is included between the heat energy recovery and storage module 9 and the first heat exchanger pipe 32, and the pump 8 provides power for the flow of the medium in the second pipe loop. Figure 5As shown, the radiator includes a water storage tank connected to the liquid storage tank, used to collect condensate generated by the radiator and to recover the condensate through pipelines back to the liquid storage tank for the next cycle of the steam assembly. The heat energy recovery and storage module 9 is an energy storage device containing a phase change material. The phase change material includes one or more combinations of the following materials: paraffin waxes, fatty acids, alcohols, hydrated salts, eutectic molten salts, and organic-organic / organic-inorganic eutectics. The phase change temperature range of the phase change material can be adjusted from -15℃ to 80℃ depending on the application scenario. The condensation heat recovered by the heat energy recovery and storage module can be used to heat domestic hot water, and the recovered cold energy can be used for food preservation.

[0057] Reviewing the first and second embodiments, in the first embodiment, when the first heat exchanger is a condenser, it can be designed as an outdoor unit and placed outdoors, while the remaining parts can be integrated into a single indoor unit, such as a floor-standing unit, placed on the indoor floor. In the second embodiment, the first heat exchanger is a type that enables heat exchange between two media, such as a shell-and-shell heat exchanger. In this embodiment, the heat recovery and storage module can be designed outdoors or in another room, while the remaining components can be designed and manufactured as a single indoor unit, such as a floor-standing unit, placed indoors to directly provide cool or hot air. Furthermore, at least one radiator and fan can be installed in at least one independent room, while the remaining components can be designed and manufactured as a single indoor unit, such as a floor-standing unit, placed outdoors or in another room, providing cool or hot air to the room in a distributed manner. Furthermore, under the two solutions mentioned above, the integrated indoor unit, due to the use of compressor components, can also be equipped with sound insulation devices to insulate the noise-generating components, including the compressor, thereby minimizing the overall operating noise of the indoor unit and further meeting the needs of indoor use scenarios.

[0058] Through the above technical solution, this invention achieves multi-purpose functionality with a single device. The heat or cold generated by the compressor during summer or winter operation can be recovered and stored for other uses, such as hot water supply, cold water preservation, or the production of insulated bags for cold chain transportation. Furthermore, the coordinated operation of the steam component and compressor allows for flexible control of the heating rate based on ambient temperature, adapting to more diverse application scenarios. The built-in steam component for producing drinking water can also meet daily drinking water needs. This truly represents a technological breakthrough in energy saving, environmental protection, and high efficiency across multiple dimensions.
