[0002] To ensure that the heating temperature of the heating device can always meet the user's needs, gas is usually used to power the heating device. However, the use of gas has a certain impact on the environment. At present, clean energy such as solar energy, air energy, and solar energy are commonly used to power the heating device. However, since these clean energy sources are more dependent on energy collection, they may not be able to provide users with a stable heating temperature at all times. In other words, the heating effect and environmental friendliness cannot be guaranteed. Utility Model Content

[0003] Therefore, it is necessary to provide a heating system that guarantees heating performance and is environmentally friendly in order to address the above problems.

[0004] A heating system includes a photovoltaic power supply device, a grid power supply device, and a heating device, wherein the photovoltaic power supply device is connected to the heating device for power supply, and the grid power supply device is connected to the heating device for power supply.

[0005] When the photovoltaic power generation storage capacity of the photovoltaic power supply device is greater than a preset power threshold, the photovoltaic power supply device supplies power to the heating device.

[0006] When the photovoltaic power generation storage capacity corresponding to the photovoltaic power supply device is not greater than the preset power threshold, and when the light conditions of the environment where the photovoltaic power supply device is located do not meet the preset light conditions, the grid power supply device supplies power to the heating device.

[0007] The heating device operates when it detects power supply from the grid power supply device or the photovoltaic power supply device.

[0008] In one embodiment, the heating device includes an integrated air conditioner and floor heating unit, wherein the inlet of the water tank of the floor heating unit is connected to the indoor heat exchanger of the integrated air conditioner and floor heating unit, and the outlet of the water tank is connected to the indoor heating pipe.

[0009] In one embodiment, the water tank is equipped with a temperature regulator for adjusting the outlet water temperature of the water tank.

[0010] In one embodiment, the water tank includes an adjacent first inner tank and a second inner tank, the first inner tank being connected to the water inlet of the water tank, the second inner tank being connected to the water outlet of the water tank, and the temperature regulator being placed in the first inner tank or the second inner tank.

[0011] The first inner tank stores water flowing in from the inlet of the water tank;

[0012] The second inner liner stores water that flows into the first inner liner;

[0013] When the air conditioner and floor heating unit is turned on, the temperature regulator adjusts the water temperature in the inner tank corresponding to the set temperature of the air conditioner and floor heating unit.

[0014] In one embodiment, the temperature regulator includes a temperature sensor and a heating device; the temperature sensor is used to detect the water temperature in the inner tank where the temperature sensor is placed; when the water temperature in the inner tank where the temperature sensor is placed is detected to be lower than a first preset water temperature threshold, the heating device heats the water in the inner tank where the temperature sensor is placed, wherein the first preset water temperature threshold corresponds to the set temperature.

[0015] In one embodiment, when the temperature regulator is placed in the first inner liner, the second inner liner is made of heat-insulating material.

[0016] In one embodiment, the first inner liner and the second inner liner are connected by a valve and a connecting pipe, the connecting pipe providing a flow channel for water flowing from the first inner liner to the second inner liner, and the valve controlling the opening and closing of the connecting pipe.

[0017] In one embodiment, when the temperature regulator is placed in the first inner tank, the valve opens when the water temperature in the first inner tank is detected to be not lower than a second preset water temperature threshold, and the water in the first inner tank flows into the second inner tank through the connecting pipe; when the water temperature in the first inner tank is detected to be lower than the second preset water temperature threshold, the valve closes, and the water in the first inner tank does not flow into the second inner tank, wherein the second preset water temperature threshold corresponds to the set temperature.

[0018] In one embodiment, the valve opens when the water level in the first inner tank is detected to be greater than a preset water level threshold, and the water in the first inner tank flows into the second inner tank through the connecting pipe; the valve closes when the water level in the first inner tank is detected to be less than the preset water level threshold, and the water in the first inner tank does not flow into the second inner tank.

[0019] In one embodiment, the photovoltaic power supply device is connected to the grid power supply device. When the heating device is turned off and the lighting conditions of the environment where the photovoltaic power supply device is located meet the preset lighting conditions, the photovoltaic power generation device connects the photovoltaic power generation and storage capacity corresponding to the photovoltaic power supply device to the power grid corresponding to the grid power supply device.

[0020] The aforementioned heating system includes a photovoltaic power supply device, a grid power supply device, and a heating device. The photovoltaic power supply device is connected to the heating device, and the grid power supply device is also connected to the heating device. When the photovoltaic power generation storage capacity corresponding to the photovoltaic power supply device exceeds a preset power threshold, the photovoltaic power supply device supplies power to the heating device. When the photovoltaic power generation storage capacity corresponding to the photovoltaic power supply device does not exceed the preset power threshold, and the lighting conditions of the environment where the photovoltaic power supply device is located do not meet preset lighting conditions, the grid power supply device supplies power to the heating device. The heating device operates when it detects power supply from either the grid power supply device or the photovoltaic power supply device, and operates through the photovoltaic power supply device and the power grid. The power supply devices work together to supply power to the heating devices. When the photovoltaic power generation storage capacity of the photovoltaic power supply device is greater than the preset power threshold, that is, when the photovoltaic power supply device has a stable power supply capability, power is supplied to the heating devices through the photovoltaic power supply device, ensuring the environmental friendliness of the heating system. When the photovoltaic power generation storage capacity of the photovoltaic power supply device is not greater than the preset power threshold, and the ambient light conditions do not meet the preset light conditions, that is, when the photovoltaic power supply device cannot supply power and cannot generate power normally, power is supplied to the heating devices through the grid power supply device, ensuring the heating effect of the heating devices. In summary, while ensuring the heating effect of the heating devices, the environmental friendliness of the heating system is improved. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] In one embodiment, a heating system is provided. For example... Figure 1 As shown, the heating system includes a photovoltaic power supply device 100, a grid power supply device 200, and a heating device 300. The photovoltaic power supply device 100 is connected to the heating device 300 for power supply, and the grid power supply device 200 is connected to the heating device 300 for power supply.

[0030] When the heating device 300 is turned on, it sends a power supply request to the photovoltaic power supply device 100. Upon receiving the power supply request, the photovoltaic power supply device 100 detects the amount of photovoltaic power stored in its corresponding photovoltaic system. If the amount of photovoltaic power stored in its corresponding photovoltaic system is greater than a preset power threshold, the photovoltaic power supply device 100 supplies power to the heating device 300. If the amount of photovoltaic power stored in its corresponding photovoltaic system is not greater than the preset power threshold, the photovoltaic power supply device 100 detects the lighting conditions of its environment. If the lighting conditions of its environment meet preset lighting conditions, the photovoltaic power supply device 100... The photovoltaic power supply device 100 generates photovoltaic power, and the generated electricity is defined as the photovoltaic power storage capacity corresponding to the photovoltaic power supply device 100. When the photovoltaic power storage capacity corresponding to the photovoltaic power supply device 100 is greater than a preset power threshold, the photovoltaic power supply device 100 supplies power to the heating device 300. When the lighting conditions of the environment where the photovoltaic power supply device 100 is located do not meet the preset lighting conditions, the power supply request is forwarded to the grid power supply device 200. When the grid power supply device 200 receives the power supply request, it supplies power to the heating device 300. The heating device 300 operates when it detects power supply from the grid power supply device 200 or the photovoltaic power supply device 100.

[0031] The preset power threshold can be set by the user as needed, or it can be an empirical value, or it can be determined according to the heating scale of the heating device 300. Specifically, the larger the heating scale of the heating device 300, the larger the preset power threshold. Lighting conditions include, but are not limited to, illuminance and illuminance coverage (the ratio between the area of ​​the photovoltaic panel receiving light and the total area of ​​the photovoltaic panel in the photovoltaic power supply device 100). When lighting conditions include illuminance, preset lighting conditions include a preset illuminance range. The preset illuminance range can be set by the user as needed, can be an empirical value, or can be determined according to the heating scale of the heating device 300. Specifically, the larger the heating scale of the heating device 300, the larger the critical value of the illuminance that constitutes the preset illuminance range. When lighting conditions include illuminance coverage, preset lighting conditions include a preset illuminance coverage range. The preset illuminance coverage range can be set by the user as needed, can be an empirical value, or can be determined according to the heating scale of the heating device 300. Specifically, the larger the heating scale of the heating device 300, the larger the critical value of the illuminance coverage that constitutes the preset illuminance coverage range.

[0032] As one example, heating devices include, but are not limited to, air conditioners, floor heaters, and integrated air conditioner-floor heater units.

[0033] Optionally, when the air conditioner and floor heating unit is set as a heating device, a larger heating range can be achieved, which is suitable for various complex heating scenarios. The air conditioner and floor heating unit integrates the air conditioner and floor heating unit into one unit, which can reduce the unnecessary space occupied by the equipment to a certain extent.

[0034] Understandably, when a floor heating system (or an integrated air conditioner and floor heating unit) provides indoor heating by heating hot water through an indoor heat exchanger, if the indoor heat exchanger is directly connected to the indoor heating pipes, meaning the hot water heated by the indoor heat exchanger can be directly supplied to the indoor heating pipes, and the indoor heat exchanger only heats up when the floor heating system (or integrated air conditioner and floor heating unit) is started, users need to wait multiple times for the indoor heat exchanger to heat up, resulting in low temperature regulation efficiency of the floor heating system (or integrated air conditioner and floor heating unit).

[0035] As one embodiment, the heating device 300 includes an integrated air conditioner and floor heating unit, such as... Figure 2 As shown, the inlet end of the water tank 310 of the air conditioner-floor heating unit is connected to the indoor heat exchanger 320 of the air conditioner-floor heating unit, and the outlet end of the water tank 310 is connected to the indoor heating pipe 400.

[0036] Thus, a water tank 310 is installed between the indoor heat exchanger 320 and the indoor heating pipe 400 of the underfloor heating system (or integrated air conditioner and underfloor heating unit). The water tank 310 can store the hot water that has been heated by the indoor heat exchanger 320. When the underfloor heating system (or integrated air conditioner and underfloor heating unit) is turned on, that is, when the underfloor heating system (or integrated air conditioner and underfloor heating unit) needs to provide heating, the hot water stored in the water tank 310 can be transported to the indoor heating pipe 400 through the outlet of the water tank 310 to achieve indoor heating. Before the user uses the underfloor heating system (or integrated air conditioner and underfloor heating unit), the heated hot water can be prepared in advance and stored in the water tank 310. When the user uses the underfloor heating system (or integrated air conditioner and underfloor heating unit), there is no need to wait for the indoor heat exchanger to heat the water, which improves the temperature regulation efficiency of the underfloor heating system (or integrated air conditioner and underfloor heating unit).

[0037] Furthermore, the indoor heating pipe 400 includes at least one of indoor underfloor heating coils and domestic water coils.

[0038] In this way, underfloor heating can provide both indoor heating and domestic hot water.

[0039] It is understandable that after installing a water tank 310 between the indoor heat exchanger 320 and the indoor heating pipe 400 of the underfloor heating system, since the underfloor heating system may not be turned on all the time, the water tank 310 may contain water that has cooled down and has not been delivered to the indoor heating pipe 400. When the underfloor heating system is turned on again, the indoor heat exchanger 320 will continuously deliver hot water to the water tank 310. In this case, the previously stored cooled water in the water tank 310 will mix with the newly delivered hot water in the indoor heat exchanger 320. If the mixed water in the water tank 310 is directly delivered to the indoor heating pipe 400, it will cause the heating temperature of the underfloor heating system to be unstable, that is, the heating effect of the underfloor heating system will not meet the user's expectations.

[0040] As an example, such as Figure 3 As shown, a temperature regulator 330 is installed inside the water tank 310, which is used to adjust the outlet water temperature of the water tank 310.

[0041] Furthermore, when the air conditioner and floor heating unit is turned on, the temperature regulator 330 adjusts the outlet water temperature of the water tank 310 according to the set temperature of the air conditioner and floor heating unit.

[0042] Thus, when the underfloor heating is turned on, the temperature regulator 330 configured inside the water tank 310 adjusts the temperature of the water in the water tank 310, ensuring that the water tank 310 delivers water at a stable temperature to the indoor heating pipes 400, thereby ensuring a stable heating temperature for the underfloor heating system.

[0043] It is understandable that when the water tank 310 has a large capacity, there may be enough hot water stored in the water tank 310 to supply heat to the underfloor heating system multiple times. However, each time the underfloor heating system is turned on, the temperature regulator 330 needs to adjust the temperature of all the water in the water tank 310. In reality, only a portion of the water used for heating needs to be adjusted, thus wasting unnecessary resources.

[0044] As an example, such as Figure 4 As shown, the water tank 310 includes an adjacent first inner tank 311 and a second inner tank 312. The first inner tank 311 is connected to the water inlet of the water tank 310, and the second inner tank 312 is connected to the water outlet of the water tank 310. The temperature regulator 330 is placed in the first inner tank 311.

[0045] Wherein: the first inner tank 311 stores water flowing in from the water inlet of the water tank 310; the second inner tank 312 stores water flowing in from the first inner tank 311; when the air conditioner and floor heating unit is turned on, the temperature regulator 330 adjusts the water temperature in the first inner tank 311 according to the set temperature of the air conditioner and floor heating unit.

[0046] As another embodiment, such as Figure 5 As shown, the water tank 310 includes an adjacent first inner tank 311 and a second inner tank 312. The first inner tank 311 is connected to the water inlet of the water tank 310, and the second inner tank 312 is connected to the water outlet of the water tank 310. The temperature regulator 330 is placed in the second inner tank 312.

[0047] Wherein: the first inner tank 311 stores water flowing in from the water inlet of the water tank 310; the second inner tank 312 stores water flowing in from the first inner tank 311; when the air conditioner and floor heating unit is turned on, the temperature regulator 330 adjusts the water temperature in the second inner tank 312 according to the set temperature of the air conditioner and floor heating unit.

[0048] The capacity of the first inner tank 311 and the second inner tank 312 can be the same or different, and can be set according to the heating scale of the underfloor heating system. Specifically, the larger the heating scale of the underfloor heating system, the larger the capacity of the second inner tank 312.

[0049] Thus, with the temperature regulator 330 located in the first inner tank 311 or the second inner tank 312, the water temperature only needs to be adjusted in one of the inner tanks (the first inner tank 311 or the second inner tank 312) of the water tank 310, which reduces the amount of water that needs to be repeatedly adjusted and reduces unnecessary resource consumption.

[0050] As one embodiment, the temperature regulator 330 includes a temperature sensor and a heating device; when the temperature regulator 330 is placed in the first inner tank 311, the temperature sensor is used to detect the water temperature in the first inner tank 311; when the water temperature in the first inner tank 311 is detected to be lower than a first preset water temperature threshold, the heating device heats the water in the first inner tank 311, wherein the first preset water temperature threshold corresponds to a set temperature.

[0051] In another embodiment, the temperature regulator 330 includes a temperature sensor and a heating device; when the temperature regulator 330 is placed in the second inner tank 312, the temperature sensor is used to detect the water temperature in the second inner tank 312; when the water temperature in the second inner tank 312 is detected to be lower than a first preset water temperature threshold, the heating device heats the water in the second inner tank 312, wherein the first preset water temperature threshold corresponds to a set temperature.

[0052] The first preset water temperature threshold can be the same as the set temperature. However, considering that the set temperature is usually the actual heating temperature when the user uses the air conditioner and floor heating integrated unit, and that there may be some heat loss when hot water is transported to various heating purposes through the indoor heating pipes 400, the first preset water temperature threshold is usually set higher than the set temperature. This ensures that the actual heating of the air conditioner and floor heating integrated unit can meet the set temperature, that is, ensures that the heating effect of the air conditioner and floor heating integrated unit can meet the user's expectations.

[0053] In the case where the temperature regulator 330 is placed in the first inner tank 311, the corresponding first preset water temperature threshold can be the same as when the temperature regulator 330 is placed in the second inner tank 312. However, considering that when the temperature regulator 330 is placed in the first inner tank 311, the hot water heated in the first inner tank 311 is not directly delivered to the indoor heating pipe 400 through the outlet of the water tank 310, but first flows through the second inner tank 312, and then is indirectly delivered through the outlet of the water tank 310 connected to the second inner tank 312. Since the hot water heated in the first inner tank 311 may experience some heat loss during its journey through the second inner tank, the first preset water temperature threshold corresponding to the temperature regulator 330 placed in the first inner tank 311 is usually higher than the first preset water temperature threshold corresponding to the temperature regulator 330 placed in the second inner tank 312. This ensures that the actual heating of the air conditioner and floor heating unit can meet the set temperature, that is, it ensures that the heating effect of the air conditioner and floor heating unit can meet the user's expectations.

[0054] Understandably, when the temperature regulator 330 is placed in the first inner tank 311, it can only ensure that the water temperature entering the second inner tank 312 from the first inner tank 311 is stable, but it cannot ensure that the water temperature of the water delivered from the second inner tank 312 through the outlet of the water tank 310 to the indoor heating pipe 400 is stable. Furthermore, it cannot ensure that the heating temperature of the underfloor heating system is stable, that is, it cannot ensure that the heating effect of the underfloor heating system can meet the user's expectations.

[0055] In another embodiment, if the temperature regulator 330 is placed in the first inner liner 311, the temperature regulator 330 is further placed in the second inner liner 312.

[0056] Thus, by adding a temperature regulator 330 to the second inner tank 312, even if the water temperature in the second inner tank 312 does not meet the first preset water temperature threshold, the added temperature regulator 330 can ensure as much as possible that the water temperature delivered from the second inner tank 312 through the outlet of the water tank 310 to the indoor heating pipe 400 is stable. Furthermore, it can ensure the stability of the heating temperature of the underfloor heating system, that is, it can ensure that the heating effect of the underfloor heating system can meet the user's expectations.

[0057] It is understandable that when both the first inner tank 311 and the second inner tank 312 are equipped with temperature regulators 330, water may be heated in the first inner tank 311 by the temperature regulator 330, and then heated in the second inner tank 312 by the temperature regulator 330, resulting in unnecessary consumption of heating resources.

[0058] As one embodiment, when the temperature regulator 330 is placed in the first inner liner 311, the second inner liner 312 is made of heat-insulating material.

[0059] In this way, the water temperature of the water transported from the second inner tank 312 through the outlet of the water tank 310 to the indoor heating pipe 400 can be kept as stable as possible through the second inner tank 312 under the insulation material. Furthermore, the heating temperature of the underfloor heating system can be kept stable, that is, the heating effect of the underfloor heating system can meet the user's expectations, and there is no need to add a temperature regulator 330 and repeatedly heat the water with the temperature regulator 330, which reduces unnecessary resource and cost consumption.

[0060] As one embodiment, the body of the first inner liner 311 is in close contact with the body of the second inner liner 312, and the height of the liner wall between the first inner liner 311 and the second inner liner 312 is lower than the height of the water tank 310.

[0061] In this way, water in the first inner liner 311 can flow to the second inner liner 312 through the liner wall between the first inner liner 311 and the second inner liner 312 when it is stored to a certain height.

[0062] Understandably, if water in the first inner tank 311 only flows into the second inner tank 312 through the tank wall between the first inner tank 311 and the second inner tank 312 when the first inner tank 311 is full, and the capacity of the first inner tank 311 is large, it is easy for water in the first inner tank 311 to not flow into the second inner tank 312 in time. This makes the process of the second inner tank 312 delivering water to the indoor heating pipe 400 take a long time, resulting in low temperature regulation efficiency of the floor heating system.

[0063] As one embodiment, the first inner liner 311 and the second inner liner 312 are connected by a valve and a connecting pipe. The connecting pipe provides a flow channel for water flowing from the first inner liner to the second inner liner, and the valve is used to control the opening and closing of the connecting pipe.

[0064] In this way, the flow of water from the first inner tank 311 into the second inner tank 312 can be flexibly controlled through valves and connecting pipes. This avoids the situation where water in the first inner tank 311 does not flow into the second inner tank 312 in time, reduces the time spent by the second inner tank 312 in delivering water to the indoor heating pipe 400, and thus improves the temperature regulation efficiency of the floor heater.

[0065] Furthermore, if the water level in the first inner liner 311 is detected to be greater than the preset water level threshold, the valve opens, and the water in the first inner liner 311 flows into the second inner liner 312 through the connecting pipe; if the water level in the first inner liner 311 is detected to be less than the preset water level threshold, the valve closes, and the water in the first inner liner 311 does not flow into the second inner liner 312.

[0066] The preset water volume threshold can be set by the user as needed or based on experience; there are no restrictions here.

[0067] In this way, by setting the amount of water flowing from the first inner tank 311 into the second inner tank 312, the time it takes for water in the first inner tank 311 to flow into the second inner tank 312 is reduced, which further reduces the time it takes for the second inner tank 312 to transport water to the indoor heating pipe 400, thereby improving the temperature regulation efficiency of the floor heater.

[0068] It is understandable that with the temperature regulator 330 placed in the first inner tank 311, the second inner tank 312 usually does not have a temperature regulator 330. That is, it usually does not have the function of heating the hot water in the second inner tank 312. Therefore, there may be a situation where the water temperature flowing into the second inner tank 312 through the connecting pipe is not high enough when the valve of the first inner tank 311 is opened. In this case, the water temperature of the water delivered from the second inner tank 312 to the indoor heating pipe 400 is not high enough to meet the set temperature for heating. In other words, the heating effect of the air conditioner and floor heating unit cannot meet the user's expectations.

[0069] As one embodiment, when the temperature regulator 330 is placed in the first inner tank 311, the valve opens when the water temperature in the first inner tank 311 is detected to be not lower than the second preset water temperature threshold, and the water in the first inner tank 311 flows into the second inner tank 312 through the connecting pipe; when the water temperature in the first inner tank 311 is detected to be lower than the second preset water temperature threshold, the valve closes, and the water in the first inner tank 311 does not flow into the second inner tank 312, wherein the second preset water temperature threshold corresponds to the set temperature.

[0070] It is understandable that, since the first preset water temperature threshold is the critical value of the water temperature in the first inner tank 311 for heating, that is, the water temperature in the first inner tank 311 is unlikely to exceed the first preset water temperature threshold, the second preset water temperature threshold is not higher than the first preset water temperature threshold.

[0071] Thus, with the temperature regulator 330 placed in the first inner tank 311, by setting the water temperature conditions for the water flowing from the first inner tank 311 into the second inner tank 312, it is ensured that the water temperature flowing into the second inner tank 312 through the connecting pipe when the valve of the first inner tank 311 is opened can be high enough. At this time, the water temperature of the water delivered from the second inner tank 312 to the indoor heating pipe 400 can meet the set temperature for heating, that is, the heating effect of the air conditioner and floor heating integrated unit can meet the user's expectations.

[0072] As one embodiment, when the temperature regulator 330 is placed in the first inner tank 311, if the water temperature in the first inner tank 311 is detected to be not lower than the second preset water temperature threshold and the water volume in the first inner tank 311 is greater than the preset water volume threshold, the valve opens and the water in the first inner tank 311 flows into the second inner tank 312 through the connecting pipe; if the water temperature in the first inner tank 311 is detected to be lower than the second preset water temperature threshold, and / or the water volume in the first inner tank 311 is not greater than the preset water volume threshold, the valve closes and the water in the first inner tank 311 does not flow into the second inner tank 312.

[0073] Thus, considering the water temperature and volume flowing from the first inner tank 311 into the second inner tank 312, it can be ensured that the water temperature flowing from the first inner tank 311 into the second inner tank 312 through the connecting pipe is sufficiently high when the valve is opened, while reducing the time spent by the water in the first inner tank 311 flowing into the second inner tank 312. Therefore, it ensures that the heating effect of the air conditioner and floor heating unit can meet the user's expectations and the temperature regulation efficiency of the air conditioner and floor heating unit can be guaranteed.

[0074] It is understandable that the photovoltaic power supply device 100 turns on and generates photovoltaic power when the lighting conditions of the environment where the photovoltaic power supply device 100 is located meet the preset lighting conditions. The photovoltaic power generation storage capacity of the photovoltaic power supply device 100 after photovoltaic power generation is limited. Therefore, when the heating device 300 is turned off, the photovoltaic power generation storage capacity of the photovoltaic power supply device 100 has nowhere to be consumed, thus wasting the current good lighting conditions.

[0075] As one embodiment, the photovoltaic power supply device 100 is connected to the grid power supply device 200. When the heating device 300 is turned off and the lighting conditions of the environment where the photovoltaic power supply device 100 is located meet the preset lighting conditions, the photovoltaic power generation device 100 connects the photovoltaic power generation and storage power corresponding to the photovoltaic power supply device 100 to the grid corresponding to the grid power supply device 200.
