[0118] The embodiments of this specification provide a multi-media heat exchange device. Please refer to Figures 1 to 9 , which shows a schematic structural diagram of the multi-media heat exchange device 10 in an embodiment of this specification.

[0119] As Figure 1 shown, the multi-media heat exchange device 10 includes a three-channel heat exchange device 11 and a flow rate regulating device 12.

[0120] The three-channel heat exchange device 11 may include a first channel 111, a second channel 112, and a third channel 113 that are isolated from each other. The heat exchange medium flowing in the first channel 111 can exchange heat with the heat exchange medium flowing in the second channel 112. The heat exchange medium flowing in the second channel 112 can exchange heat with the heat exchange medium flowing in the third channel 113.

[0121] The inlet of the first channel 111 is communicated with the outlet of the first heat source 20. The outlet of the first channel 111 is communicated with the inlet of the first heat source 20. The heat exchange medium in the first heat source 20 flows into the first channel 111 for heat exchange. Among them, the first heat source 20 may include central heating.

[0124] The flow rate regulating device 12 may be arranged on the pipeline communicating with the third channel 113 between the water source 40 and the water using device 50. That is, the flow rate regulating device 12 may be arranged on the pipeline between the outlet of the water source 40 and the inlet of the third channel 113, or arranged on the pipeline between the water using device 50 and the outlet of the third channel 113. The flow rate regulating device 12 can be used to regulate the flow rate of the heat exchange medium flowing in the third channel 113.

[0125] In the above embodiments, by providing a three-channel heat exchange device, the heat exchange medium flowing out of the first heat source flows into the first channel of the heat exchange device, the heat exchange medium flowing out of the second heat source flows into the second channel of the heat exchange device, and the water flowing out of the water source can flow into the third channel and then flow out to the water-using device. Since heat exchange can occur between the first channel and the second channel of the three-channel heat exchange device, and heat exchange can occur between the second channel and the third channel, the dual heat sources can be integrated and scheduled to heat domestic water. Since the first channel, the second channel, and the third channel are isolated from each other, problems such as unstable water pressure and system fouling in the direct connection scheme can be avoided. Further, by providing a flow regulating device, the water flow rate flowing in the third channel can be regulated, so that the outlet water temperature of the water-using device can be adjusted according to user requirements or system settings, providing domestic water with a large amount of water, healthy constant temperature, and meeting the user's heating requirements energy-efficiently and comfortably.

In this embodiment, the flow rate of the heat exchange medium flowing in the third channel can be regulated by adjusting the rotation speed of the variable frequency water pump.

One end of the connecting pipe 13 is connected to the first pipeline between the inlet of the third channel 113 and the water source 40.

Although this specification provides method operation steps or device structures as shown in the following embodiments or drawings, more or fewer operation steps or module units may be included in the method or device based on routine or non-creative labor. In steps or structures where there is no necessary causal relationship logically, the execution order of these steps or the module structure of the device is not limited to the execution order or module structure described in the embodiments of this specification and shown in the drawings. When the method or module structure is applied to an actual device or terminal product, it can be executed sequentially or in parallel according to the method or module structure connection shown in the embodiments or drawings (for example, in an environment of parallel processors or multi-threaded processing, or even a distributed processing environment).

[0175] Specifically, as Figure 15 shown, the control method for a multi-media heat exchange device provided in an embodiment of this specification may include the following steps:

In one embodiment, the method in this embodiment can be applied to the controller in the multi-media heat exchange device. In another embodiment, the controller can also be arranged in the second heat source. The controller can obtain the water use set temperature and the first temperature data.

[0178] Among them, the water use set temperature can be the water use temperature preset by the user or the system default water use set temperature. In one embodiment, the liquid flowing out of the second heat source can enter the second flow channel to heat the liquid flowing in the third flow channel. The first temperature data can be the temperature of the heat exchange medium detected by the first temperature sensor, and the first temperature sensor is arranged at the outlet of the third flow channel or between the outlet of the third flow channel and the water use device. The first temperature data can represent the temperature of the liquid flowing out of the outlet of the third flow channel or the temperature of the liquid flowing into the water use device.

[0179] Step S152, control the flow regulating device to adjust the flow rate of the heat exchange medium flowing in the third flow channel according to the water use set temperature and the first temperature data.

[0180] After obtaining the set water temperature and the first temperature data, the flow rate of the heat exchange medium in the third flow channel can be controlled by adjusting the flow rate regulating device according to the set water temperature and the first temperature data. In this embodiment, the flow rate can be adjusted by adjusting the rotation speed of the variable frequency water pump, or by adjusting the opening degree of the solenoid valve or the three-way valve.

[0181] In the above embodiment, the set water temperature and the first temperature data can be obtained, and based on the set water temperature and the first temperature data, the flow rate of the heat exchange medium flowing in the third flow channel can be adjusted to meet the user's water use requirements.

In the case where it is determined that the temperature corresponding to the first temperature data is greater than the first preset temperature, the opening degree of the solenoid valve can be controlled to increase, so that the flow rate of the heat exchange medium flowing in the third flow channel is reduced, and the flow rate of the heat exchange medium flowing in the connecting pipe is increased.

[0186] In another embodiment, the solenoid valve may be disposed on the pipeline between one end of the communication pipe and the inlet of the third flow channel. When it is determined that the temperature corresponding to the first temperature data is greater than the first preset temperature, the opening degree of the solenoid valve can be controlled to decrease, so that the flow rate of the heat exchange medium flowing in the third flow channel decreases, and the flow rate of the heat exchange medium flowing in the communication pipe increases.

The solenoid valve can adjust the flow rate of the fluid flowing through the communication pipe or adjust the flow rate of the fluid flowing in the third flow channel. When it is determined that the temperature corresponding to the first temperature data is greater than the first preset temperature, the opening degree of the solenoid valve can be controlled to decrease, so that the flow rate of the heat exchange medium flowing in the third flow channel decreases, and the flow rate of the heat exchange medium flowing in the communication pipe increases.

[0188] In another embodiment, the flow rate regulating device may be a three-way valve. The three-way valve can adjust the flow rate relationship between the fluids flowing in the communication pipe and the third flow channel.

The first end of the three-way valve is connected to the water source, the second end of the three-way valve is connected to the inlet of the third flow channel, and the third end of the three-way valve is connected to one end of the communication pipe. When it is determined that the temperature corresponding to the first temperature data is greater than the first preset temperature, the opening degree of the second end of the three-way valve can be controlled to decrease and / or the opening degree of the third end of the three-way valve can be controlled to increase, so that the flow rate of the heat exchange medium flowing in the third flow channel decreases, and the flow rate of the heat exchange medium flowing in the communication pipe increases.

[0190] In another embodiment, the three-way valve is located at the second connection between the communication pipe and the second pipeline. The first end of the three-way valve is connected to the water using device, the second end of the three-way valve is connected to the outlet of the third flow channel, and the third end of the three-way valve is connected to the other end of the communication pipe. When it is determined that the temperature of the heat exchange medium flowing into the water using device is greater than the first preset temperature, the opening degree of the second end of the three-way valve can be controlled to decrease and / or the opening degree of the third end of the three-way valve can be controlled to increase, so that the flow rate of the heat exchange medium flowing in the third flow channel decreases, and the flow rate of the heat exchange medium flowing in the communication pipe increases.

[0191] By the above method, when the temperature of the heat exchange medium flowing out of the third flow channel is too high, the flow rate regulating device can be used to mix the high-temperature heat exchange medium flowing out of the third flow channel with the low-temperature heat exchange medium flowing out of the water source via the communication pipe, thereby reducing the water temperature flowing out to the water using device and enabling the utilization of the high-temperature water.

Since heat exchange can occur between the first channel and the second channel of the three-channel heat exchange device, and heat exchange can occur between the second channel and the third channel, the dual heat sources can be integrated and scheduled to heat domestic water. Since the first channel, the second channel, and the third channel are isolated from each other, problems such as unstable water pressure and system fouling in the direct connection scheme can be avoided. Further, by setting up a flow regulating device, the water flow rate flowing in the third channel can be regulated, so that the outlet water temperature of the water-using device can be adjusted according to user needs or system settings, providing domestic water with a large amount of water, healthy constant temperature, and meeting the user's heating needs energy-efficiently and comfortably.
