In the heat storage water tank provided by the embodiment, due to the arrangement of the single heat exchange coil 11, compared with the arrangement of the double heat exchange coils, the manufacturing cost and the complexity can be effectively reduced, and the effective volume in the heat storage water tank can be improved; and the air source heat pump 3 and the second heat source 4 are respectively connected on the single heat exchange coil 11 in parallel through one connecting piece at the water outlet and the water inlet of the single heat exchange coil 11, so that water in the heat storage water tank can be heated through the two heat sources, the heating efficiency of the heat storage water tank is improved, and the user needs are met.
Specifically, with continued reference to fig. 3, the heat storage water tank provided in this embodiment further includes a liner 12 installed in the tank body 1, and the single heat exchange coil 11 is located in the liner 12, so that the liner 12 can store a certain amount of hot water, has a good heat preservation effect, and can also play a role in stably supporting the tank body 1, thereby being beneficial to enhancing the structural strength of the whole heat storage water tank. Further, in this embodiment, the liner 12 is made of stainless steel, carbon steel, titanium alloy, etc., and the specific material is selected according to the environment in which the hot water tank is used and the required functions. Therefore, those skilled in the art may select according to different environments, usage scenarios and requirements in combination with actual requirements, and the present utility model is not limited thereto.
Specifically, in this embodiment, the first connecting member 21 is an electromagnetic three-way valve, a temperature sensor 5 is disposed on a pipeline connected to the first connecting member 21, the temperature sensor 5 can detect a temperature value of hot water output from a water outlet of the single heat exchange coil 11, the temperature sensor 5 is in signal connection with a controller (not shown in the figure), and the controller can determine whether the first inlet 213 is communicated with the first outlet 211 or is communicated with the second outlet 212 according to whether the water outlet temperature value reaches a set temperature value.
In this embodiment, the temperature value is set to 35 ℃ to meet the requirement of heat source switching, when the water temperature in the tank 1 is lower than 35 ℃ (low water temperature state), the first inlet 213 is communicated with the first outlet 211, the second heat source 4 is opened, so that the high-temperature heat exchange fluid medium in the second heat source 4 can enter the single heat exchange coil 11 through the third inlet 223, the water stored in the inner container 12 is gradually heated through the heat exchange coil 11, the water in the inner container 12 is gradually heated, the low-temperature heat exchange fluid medium after heat exchange is returned to the second heat source 4 through the first outlet 211 for heating, and circulation is performed according to the above process, so that the water in the inner container 12 can be heated to 35 ℃ (water temperature state), thereby completing the first heating stage.
When the temperature sensor 5 detects that the outlet water temperature of the single heat exchange coil 11 reaches 35 ℃, the temperature sensor 5 transmits a temperature signal to the controller, the controller controls the first inlet 213 to be communicated with the second outlet 212, the air source heat pump 3 is started, the second heat source 4 is closed, the high-temperature heat exchange fluid medium in the air source heat pump 3 can enter the single heat exchange coil 11 through the second inlet 222 and continuously exchange heat with water in the inner container 12, the low-temperature heat exchange fluid medium after heat exchange is re-transmitted back to the air source heat pump 3 through the first outlet 211 to be heated, and the circulation is performed according to the process, so that the water in the inner container 12 can be heated to a preset temperature (high water temperature state), and the second heating stage is completed.
It will be appreciated that the heating effect of the existing air source heat pump 3 is typically achieved by operation of the compressor, which consumes some electrical energy. Therefore, in the heating process, the air source heat pump 3 needs to consume corresponding electric energy, thereby resulting in higher energy consumption; in addition, the air source heat pump 3 itself has energy loss, for example, the flow of cooling fluid medium, the operation of a fan and the like all cause a certain energy loss, and inevitably. Therefore, in this embodiment, the first connector 21 is an electromagnetic three-way valve, so that the air source heat pump 3 and the second heat source 4 can be used to heat the water in the inner container 12 in a staged manner, thereby saving the energy consumed by the air source heat pump 3 from the low water temperature state to the medium water temperature state, and achieving the effect of saving more energy.

When the solar heat pump is adopted as the second heat source 4, no harmful gas is generated, so that the solar heat pump has the advantages of cleanness and environmental protection; and the solar heat pump can effectively help to reduce energy consumption and cost, thereby saving energy cost. When a boiler is used as the second heat source 4, it has the advantages of being independent of the ambient temperature, being usable in all climatic conditions, effectively avoiding the problem of reduced efficiency of the air source heat pump 3 at extreme air temperatures, and having higher thermal efficiency, easy maintenance and strong durability. Both heat sources can replace the air source heat pump 3 to heat the water in the inner container 12 from a low water temperature state to a medium water temperature state, and have different advantages compared with the air source heat pump 3. Therefore, the present utility model is not limited to the type of the second heat source 4, and one skilled in the art can select the type of the second heat source 4 according to the actual use environment.
Optionally, as shown in fig. 3, the tank 1 is further provided with a cold water joint 13 and a hot water joint 14, where the cold water joint 13 and the hot water joint 14 are both communicated with the liner 12, in this embodiment, the cold water joint 13 is disposed at the bottom of the tank 1, and the hot water joint 14 is disposed at the top of the tank 1.
