Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water heater and air conditioner dual-purpose all-in-one machine. Background Art

[0002] Traditional air conditioners are mainly composed of an indoor unit and an outdoor unit. Using the Carnot cycle principle, the indoor unit absorbs indoor heat, and then uses the refrigerant (heat medium) to transport the heat to the outdoor unit and discharge it into the atmosphere. Traditional air conditioners have several problems:

[0003] 1. Air conditioning operation causes the outdoor temperature to rise, exacerbating the greenhouse effect. At the same time, the hot air generated by the air conditioner outdoor unit will also cause discomfort to people doing outdoor activities;

[0004] 2. Traditional air conditioners simply transfer heat from indoors to outdoors during the entire operation process. Not only does it fail to reduce heat emissions, but it also consumes electricity during the heat transfer process, adding extra heat, which does not meet the needs of energy conservation and emission reduction.

[0005] 3. Traditional air conditioning systems use heat pumps and electric heating. Heat pumps require a certain outdoor temperature; low outdoor temperatures can significantly reduce heating efficiency. While electric heating is unaffected by outdoor temperatures, it requires a high-powered heater to quickly raise indoor temperatures, which can lead to high energy consumption and impact on the power grid.

[0006] In view of this, the present invention proposes a water heater and air conditioner dual-purpose all-in-one unit that can save energy and reduce emissions, and this case is thus created. Utility Model Content

[0007] The purpose of the utility model is to provide a water heater and air conditioner dual-purpose all-in-one machine to realize the conversion and utilization of air conditioning heat, thereby achieving energy saving and emission reduction effects.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] The utility model provides a water heater and air conditioner dual-purpose all-in-one machine, comprising:

[0010] The air conditioner indoor unit is equipped with a first heat exchanger, which is used for exchanging heat between the indoor environment and the heat medium;

[0011] The air conditioner outdoor unit is equipped with a second heat exchanger, which is used for heat exchange between the heat medium and the outdoor environment;

[0012] The hot water tank is equipped with a third heat exchanger, which is used to exchange heat between the heat medium and the cold water / hot water in the hot water tank, so that the cold water is heated into hot water and stored, or the low-temperature heat medium is heated into a high-temperature heat medium by the hot water;

[0013] a heat medium pipe network, used for interconnecting the first heat exchanger, the second heat exchanger, and the third heat exchanger; heat medium is filled into the heat medium pipe network; the heat medium pipe network provides flow channels for the heat medium between the first heat exchanger and the second heat exchanger, between the first heat exchanger and the third heat exchanger, and between the second heat exchanger and the third heat exchanger;

[0014] The reversing valve is installed on the heat medium pipe network. It is used to control the flow direction of the heat medium in the heat medium pipe network so that:

[0015] The high-temperature heat medium flowing out of the first heat exchanger can flow into the third heat exchanger, and the low-temperature heat medium flowing out of the third heat exchanger can flow into the first heat exchanger;

[0016] Alternatively, the high-temperature heat medium flowing out of the first heat exchanger can flow into the second heat exchanger, and the low-temperature heat medium flowing out of the second heat exchanger can flow into the first heat exchanger;

[0017] Alternatively, the high-temperature heat medium flowing out of the second heat exchanger can flow into the third heat exchanger, and the low-temperature heat medium flowing out of the third heat exchanger can flow into the second heat exchanger;

[0018] Alternatively, the high-temperature heat medium flowing out of the third heat exchanger can flow into the first heat exchanger, and the low-temperature heat medium flowing out of the first heat exchanger can flow into the third heat exchanger.

[0019] Furthermore, a compressor for driving the flow of the heat medium and an expansion valve for cooling the heat medium are connected to the heat medium pipe network.

[0020] Furthermore, the first heat exchanger, the second heat exchanger, and the third heat exchanger all have a high-temperature heat medium inlet and outlet end and a low-temperature heat medium inlet and outlet end.

[0021] Furthermore, the all-in-one machine also includes a controller and a temperature sensor. The temperature sensor detects the water temperature, heat medium temperature, and indoor and outdoor air temperatures in the hot water tank 3. The controller is used to control the start / shutdown of the air conditioner indoor unit and air conditioner outdoor unit according to the water temperature, heat medium temperature, and indoor and outdoor air temperatures in the hot water tank 3, as well as the opening and closing of the reversing valve.

[0022] Furthermore, the hot water tank is equipped with an electric heating coil for heating.

[0023] After adopting the above technical solution, the working principle and beneficial effects of the water heater and air conditioner dual-purpose integrated machine of the present invention are as follows:

[0024] The utility model can realize the following working modes:

[0025] Mode A, air conditioning for cooling, water heater for heating: by controlling the reversing valve, the air conditioner outdoor unit is disconnected from the heat medium pipe network, making the heat medium pipe network between the air conditioner indoor unit and the hot water tank conductive. When the air conditioner indoor unit starts cooling, the low-temperature heat medium enters the first heat exchanger of the air conditioner indoor unit, absorbs indoor heat and turns into high-temperature heat medium. The high-temperature heat medium flows out of the first heat exchanger, flows through the heat medium pipe network to the third heat exchanger of the hot water tank, and through heat exchange, the cold water in the hot water tank is heated, and the high-temperature heat medium is cooled to a low-temperature heat medium, which flows back to the first heat exchanger of the air conditioner indoor unit. This continuous cycle achieves the effect of cooling the room and heating the cold water in the hot water tank.

[0026] Mode B: The air conditioner operates solely for cooling: When the water temperature in the hot water tank reaches the set maximum, the temperature sensor inside the hot water tank sends a signal, which controls the reversing valve, disconnecting the heat transfer piping between the indoor unit and the hot water tank. However, the heat transfer piping between the indoor unit and the outdoor unit is then connected. The high-temperature heat transfer flows to the outdoor unit's primary heat exchanger, where it exchanges heat with the ambient air. The high-temperature heat transfer dissipates heat, reducing it to low-temperature heat transfer and returning it to the indoor unit. This cycle ensures that the air conditioner can continue cooling even when the hot water tank stores the maximum amount of heat.

[0027] Mode C, water heater heating only: When the room is not cooling and the water heater is heating, the reversing valve is controlled to disconnect the indoor air conditioner from the heat medium network. The hot water tank is then connected to the outdoor air conditioner via the heat medium network, creating a traditional air-to-water heater. The low-temperature heat medium enters the second heat exchanger 21 of the outdoor air conditioner, absorbs heat, and then flows out as high-temperature heat medium. This high-temperature heat medium is then transferred through the heat medium network to the three heat exchangers in the hot water tank, causing the water temperature in the hot water tank to rise.

[0028] In mode D, the water heater heats quickly. Based on mode A or C, the electric heating coil in the hot water tank starts working to quickly heat the hot water.

[0029] Mode E: The air conditioner uses hot water alone for heating. The outdoor unit is disconnected from the heat transfer piping, leaving the heat transfer piping between the indoor unit and the hot water tank connected. The low-temperature heat transfer absorbs heat in the hot water tank and is then transferred via the compressor to the first heat exchanger in the indoor unit, where it releases the heat. When the water temperature in the hot water tank drops below a specified threshold, the tank's temperature sensor sends a signal, initiating heating of the electric heating coil, achieving continuous heating. This mode is the opposite of Mode A, enabling bidirectional heat exchange between the hot water tank and the indoor unit.

[0030] The utility model of the water heater and air conditioner dual-purpose all-in-one machine has the following beneficial effects:

[0031] 1) Reduce heat emissions: By introducing waste heat from air conditioning into the hot water tank, the heat emissions from air conditioning to the outdoor environment are reduced, thus reducing the impact of the greenhouse effect.

[0032] 2) Reduce energy consumption: The water heater converts the waste heat from the air conditioner into heat for the hot water tank, thus reducing electricity consumption. This can effectively reduce the load on the power grid, especially during peak hours of electricity consumption.

[0033] 3) Improved air conditioning and heating functions:

[0034] a. Compared to traditional heat pump heating air conditioners: The water temperature in the hot water tank is higher than the outdoor air, and water has a greater specific heat capacity than air. According to the heat formula Q = cmΔt, one unit of refrigerant absorbs more heat from hot water than from the outdoor air. Compared to traditional air conditioners, with the same indoor heating efficiency, a water heater and air conditioner can have a lower compressor power, reducing both energy consumption and the instantaneous impact of equipment startup and shutdown on the power grid, making it safer to use. Furthermore, a water heater and air conditioner primarily utilizes the heat from the hot water in the tank for indoor heating, unaffected by outdoor air temperature. Compared to traditional heat pump heating air conditioners, the heating function is more efficient and stable in extremely cold climates.

[0035] b. Compared with traditional electric heating and air conditioning: Because water has a high specific heat capacity, the hot water in the hot water tank can play a good role in heat regulation and storage. Compared with traditional electric heating and air conditioning, electric heating equipment can achieve lower power consumption, reduce electricity consumption, and reduce the instantaneous impact of equipment startup and shutdown on the power grid.

[0036] 4) Smart Home Integration: This device can be integrated with smart home systems for remote monitoring and control. Users can flexibly adjust the water heater and air conditioner functions based on weather conditions and personal preferences. For example, before returning home in the summer, activating the device in mode A can lower the indoor temperature while increasing the hot water temperature. Activating mode E before returning home in the winter can increase both the indoor temperature and the hot water temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solution of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] like Figure 1-4 As shown, the embodiment of the present invention discloses a water heater and air conditioner dual-purpose integrated machine, which includes:

[0045] The air conditioner indoor unit 1 is equipped with a first heat exchanger 11, which is used to exchange heat between the indoor environment and the heat medium (refrigerant); for example, the refrigerant can be a mixture of water and a small amount of chemicals (ethylene glycol), or a new refrigerant R410A, which is a mixture of two quasi-azeotropic elements, mainly composed of hydrogen, fluorine and carbon elements;

[0046] The air conditioner outdoor unit 2 is equipped with a second heat exchanger 21, which is used for heat exchange between the heat medium and the outdoor environment;

[0047] The hot water tank 3 is equipped with a third heat exchanger 31. The third heat exchanger 31 is used to exchange heat between the heat medium and the cold water / hot water in the hot water tank 3, so that the cold water is heated to hot water for storage, or the low-temperature heat medium is heated to a high-temperature heat medium by the hot water;

[0048] The heat medium pipe network 4 is used to interconnect the first heat exchanger 11, the second heat exchanger 21, and the third heat exchanger 31. The heat medium is filled into the heat medium pipe network, and the heat medium pipe network provides a flow channel for the heat medium between the first heat exchanger and the second heat exchanger, between the first heat exchanger and the third heat exchanger, and between the second heat exchanger and the third heat exchanger;

[0049] The reversing valve is provided on the heat medium pipe network 4. The reversing valve is used to control the flow direction of the heat medium in the heat medium pipe network 4 so that:

[0050] The high-temperature heat medium flowing out of the first heat exchanger 11 can flow into the third heat exchanger 31 , and the low-temperature heat medium flowing out of the third heat exchanger 31 can flow into the first heat exchanger 11 ;

[0051] Alternatively, the high-temperature heat medium flowing out of the first heat exchanger 11 can flow into the second heat exchanger 21 , and the low-temperature heat medium flowing out of the second heat exchanger 21 can flow into the first heat exchanger 11 ;

[0052] Alternatively, the high-temperature heat medium flowing out of the second heat exchanger 21 can flow into the third heat exchanger 31 , and the low-temperature heat medium flowing out of the third heat exchanger 31 can flow into the second heat exchanger 21 ;

[0053] Alternatively, the high-temperature heat medium flowing out of the third heat exchanger 31 may flow into the first heat exchanger 11 , and the low-temperature heat medium flowing out of the first heat exchanger 11 may flow into the third heat exchanger 31 .

[0054] like Figure 1-4 As shown, in this embodiment, the reversing valves include reversing valves 1a#, 2a#, 3a#, 4a#, 5a#, 6a#, 7a#, 8a# and 1b#, 2b#, 3b#, 4b#, 5b#, 6b#, 7b#, 8b#, wherein the reversing valves 1a#, 2a#, 3a#, 4a#, 5a# are used to control the high-temperature heat medium to enter and exit the first heat exchanger 11, the reversing valve 6a# is used to control the high-temperature heat medium to enter and exit the third heat exchanger 31, and the reversing valves 7a# and 8a# are used to control the high-temperature heat medium to enter and exit the second heat exchanger 21. The reversing valves 1b#, 2b#, 3b#, 4b#, 5b# are used to control the low-temperature heat medium to enter and exit the first heat exchanger 11, the reversing valve 6b# is used to control the low-temperature heat medium to enter and exit the third heat exchanger 31, and the reversing valves 7b# and 8b# are used to control the low-temperature heat medium to enter and exit the second heat exchanger 21.

[0055] In some embodiments, the heat medium pipe network 4 is connected to a compressor 5 for driving the flow of the heat medium and an expansion valve 6 for cooling the heat medium.

[0056] In some embodiments, the first heat exchanger 11 , the second heat exchanger 21 , and the third heat exchanger 31 all have high-temperature heat medium inlet and outlet ends and low-temperature heat medium inlet and outlet ends. Separating the high-temperature heat medium inlet and outlet ends from the low-temperature heat medium is beneficial to simplifying the heat medium pipe network 4 .

[0057] In some embodiments, the above-mentioned all-in-one machine also includes a controller and a temperature sensor. The temperature sensor detects the water temperature, heat medium temperature, and indoor and outdoor air temperatures in the hot water tank 3. The controller is used to control the start / shutdown of the air-conditioning indoor unit and the air-conditioning outdoor unit according to the water temperature, heat medium temperature, and indoor and outdoor air temperatures in the hot water tank 3, and to control the opening and closing of the reversing valve. The controller can be integrated into the air-conditioning indoor unit 1 or the water heater, or can be set separately. It usually also has a remote control device for interacting with the controller for instructions, such as a remote control, a smart mobile terminal, etc.

[0058] In some embodiments, the hot water tank 3 is equipped with an electric heating coil 32 for heating.

[0059] The utility model's water heater and air conditioner dual-purpose all-in-one machine can realize the following working modes:

[0060] A mode, air conditioning cooling, water heater heating: see Figure 1 , reversing valves 1a#, 3a#, 5a#, 6a#, 1b#, 3b#, 5b#, and 6b# are opened, and reversing valves 2a#, 4a#, 7a#, 8a#, 2b#, 4b#, 7b#, and 8b# are closed. By controlling the reversing valves, the air conditioner outdoor unit 2 is disconnected from the heat medium pipe network 4, so that the heat medium pipe network 4 between the air conditioner indoor unit 1 and the hot water tank 3 is connected. When the air conditioner indoor unit 1 starts cooling, the low-temperature heat medium is further reduced in temperature through the expansion valve 6. The low-temperature heat medium enters the first heat exchanger 11 of the air conditioner indoor unit 1, absorbs indoor heat and becomes a high-temperature heat medium. The high-temperature heat medium flows out of the first heat exchanger 11, flows through the heat medium pipe network to the third heat exchanger 31 of the hot water tank 3, and through heat exchange, the cold water in the hot water tank 3 is heated, and the high-temperature heat medium is cooled to a low-temperature heat medium, which flows back to the first heat exchanger 11 of the air conditioner indoor unit 1. This continuous cycle achieves the effect of cooling the room and heating the cold water in the hot water tank 3;

[0061] Mode B, air conditioning cooling only: When the water temperature in the hot water tank 3 rises to the set maximum temperature, the temperature sensor in the hot water tank 3 sends a signal, see Figure 2 , reversing valves 2a#, 4a#, 6a#, 2b#, 4b#, and 6b# are closed, while reversing valves 1a#, 3a#, 5a#, 7a#, 8a#, 1b#, 3b#, 5b#, 7b#, and 8b# are opened. By controlling the reversing valves, the heat medium pipe network 4 between the air conditioner indoor unit 1 and the hot water tank 3 is disconnected, while the heat medium pipe network 4 between the air conditioner indoor unit 1 and the air conditioner outdoor unit 2 is connected. The high-temperature heat medium flows to the first heat exchanger 11 of the air conditioner outdoor unit 2, exchanging heat with the atmospheric air. The high-temperature heat medium dissipates heat and is reduced to low-temperature heat medium, which then flows back to the air conditioner indoor unit 1. This cycle ensures that the air conditioner can continue cooling when the hot water tank 3 stores the maximum amount of heat.

[0062] C mode, water heater heating alone: when the room does not need to be cooled and the water heater needs to be heated, refer to Figure 3 Reversing valves 2a#, 3a#, 5a#, 6a#, 8a#, 2b#, 3b#, 5b#, 6b#, and 8b# are open, while reversing valves 1a#, 4a#, 7a#, 1b#, 4b#, and 7b# are closed. By controlling the reversing valves, air conditioner indoor unit 1 is disconnected from heat medium pipe network 4. Hot water tank 3 is then connected to air conditioner outdoor unit 2 via heat medium pipe network 4, forming a traditional air-energy water heater. The low-temperature heat medium enters second heat exchanger 21 of air conditioner outdoor unit 2, absorbs heat, and then flows out as high-temperature heat medium. This high-temperature heat medium is then transferred through heat medium pipe network 4 to third heat exchanger 31 in hot water tank 3, causing the water temperature in hot water tank 3 to rise.

[0063] In mode D, the water heater heats quickly. Based on mode A or C, the electric heating coil 32 in the hot water tank 3 is turned on to quickly heat the hot water.

[0064] E mode: The air conditioner uses hot water for heating alone. Figure 4 , reversing valves 2a#, 3a#, 4a#, 6a#, 7a#, 2b#, 3b#, 4b#, 6b#, and 7b# are opened, and reversing valves 1a#, 5a#, 8a#, 1b#, 5b#, and 8b# are closed. The air conditioner outdoor unit 2 is disconnected from the heat medium pipe network 4, allowing the heat medium pipe network 4 between the air conditioner indoor unit 1 and the hot water tank 3 to be connected. The low-temperature heat medium absorbs heat in the hot water tank 3 and is transported to the first heat exchanger 11 of the air conditioner indoor unit 1 through the compressor 5, where it releases heat. When the water temperature in the hot water tank 3 drops to a specified value, the temperature sensor in the hot water tank 3 sends a signal, and the electric heating coil 32 begins heating the hot water in the tank, achieving a continuous heating state. This mode is the opposite of mode A, thus achieving two-way heat exchange between the hot water tank 3 and the air conditioner indoor unit 1.

[0065] The advantages of using the water heater and air conditioner dual-purpose all-in-one machine of the utility model include:

[0066] 1) Reduce heat emissions: By introducing waste heat from air conditioning into the hot water tank, the heat emissions from air conditioning to the outdoor environment are reduced, thus reducing the impact of the greenhouse effect.

[0067] 2) Reduce energy consumption: The water heater converts the waste heat from the air conditioner into heat for the hot water tank, thus reducing electricity consumption. This can effectively reduce the load on the power grid, especially during peak hours of electricity consumption.

[0068] 3) Improved air conditioning and heating functions:

[0069] a. Compared to traditional heat pump heating air conditioners: The water temperature in the hot water tank is higher than the outdoor air, and water has a greater specific heat capacity than air. According to the heat formula Q = cmΔt, one unit of refrigerant absorbs more heat from hot water than from the outdoor air. Compared to traditional air conditioners, with the same indoor heating efficiency, a water heater and air conditioner can have a lower compressor power, reducing both energy consumption and the instantaneous impact of equipment startup and shutdown on the power grid, making it safer to use. Furthermore, a water heater and air conditioner primarily utilizes the heat from the hot water in the tank for indoor heating, unaffected by outdoor air temperature. Compared to traditional heat pump heating air conditioners, the heating function is more efficient and stable in extremely cold climates.

[0070] b. Compared with traditional electric heating and air conditioning: Because water has a high specific heat capacity, the hot water in the hot water tank can play a good role in heat regulation and storage. Compared with traditional electric heating and air conditioning, electric heating equipment can achieve lower power consumption, reduce electricity consumption, and reduce the instantaneous impact of equipment startup and shutdown on the power grid.

[0071] 4) Smart Home Integration: This device can be integrated with smart home systems for remote monitoring and control. Users can flexibly adjust the water heater and air conditioner functions based on weather conditions and personal preferences. For example, before returning home in the summer, activating the device in mode A can lower the indoor temperature while increasing the hot water temperature. Activating mode E before returning home in the winter can increase both the indoor temperature and the hot water temperature.

[0072] The above are only specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes made based on the design concept of this case fall within the scope of protection of this case.
