[0027] Water flow route two: When the return water electric regulating valve 4 and the water supply electric regulating valve 3 are both opened, water flows to the water supply end of the water supply main network 20, the water supply pipeline 101, the indoor water supply network 30, the return water pipeline 102 and the water outlet end of the water supply pipeline 101 in sequence; at the same time, part of the water in the return water pipeline 102 will flow to the return water branch pipe 103, and then flow into the water supply pipeline 101 and the indoor water supply network 30, forming an internal water flow circulation.

[0028] As an optional implementation, the water supply main network 20 is connected to the pipeline assembly 10 through the heat exchanger 5, so that changes in the flow and pressure of the water supply main network 20 do not affect the flow and pressure in the pipeline assembly 10 and the indoor water supply network 30. The heat exchanger 5 can be a plate heat exchanger or a shell and tube heat exchanger, etc.; the water inlet end of the water supply pipeline 101 is connected to the first outlet end of the heat exchanger 5, the water outlet end of the return water pipeline 102 is connected to the first inlet end of the heat exchanger 5, the water supply end of the water supply main network 20 is connected to the second inlet end of the heat exchanger 5, the water return end of the water supply main network 20 is connected to the second outlet end of the heat exchanger 5, the water outlet end of the water supply pipeline 101 is connected to the water inlet end of the indoor water supply network 30, and the water inlet end of the return water pipeline 102 is connected to the water outlet end of the indoor water supply network 30. Water flow route three: When the return water electric regulating valve 4 is closed and the water supply electric regulating valve 3 is opened, the water flows through the water supply end of the water supply main network 20, enters the heat exchanger 5, and then flows out from the return water end of the water supply main network 20, which is an outdoor cycle; the water flow after heat exchange in the heat exchanger 5 passes through the water supply pipeline 101, the indoor water supply network 30, the return water pipeline 102 and the heat exchanger 5 in turn, which is an indoor cycle.

[0029] Water flow route four: When the return water electric regulating valve 4 and the water supply electric regulating valve 3 are both opened, the water flows through the water supply end of the water supply main network 20, enters the heat exchanger 5, and then flows out from the return water end of the water supply main network 20, which is an outdoor cycle; the water flow after heat exchange in the heat exchanger 5 passes through the water supply pipeline 101, the indoor water supply network 30, the return water pipeline 102 and the heat exchanger 5 in turn, which is an indoor cycle; at the same time, part of the water in the return water pipeline 102 will flow to the return water branch 103, and then flow into the water supply pipeline 101 and the indoor water supply network 30, forming an internal water flow cycle.

[0030] As an optional implementation, the water flow driving component is a circulating water pump 2, and the connection between the return branch pipe 103 and the water supply pipeline 101 is located between the circulating water pump 2 and the water supply electric regulating valve 3. The circulating water pump 2 can make the water flow run at a constant flow rate, so that there is no pressure and flow fluctuation in the pipeline component 10 and the indoor water supply network 30, and the water system can be stable after the system is initially balanced.

In this way, the amount of water flowing from the return water branch pipe 103 to the water supply pipeline 101 is relatively large, and the water supply temperature is reduced after mixing until the room temperature reaches the set temperature, and the valve adjustment stops; when the real-time temperature collected by the control component 1 is lower than the set temperature, the control component 1 reversely adjusts, the opening of the return water electric regulating valve 4 is opened, the opening of the return water electric regulating valve 4 is closed or the return water electric regulating valve 4 is directly closed, so that the amount of water flowing from the return water branch pipe 103 to the water supply pipeline 101 is relatively small or no, and the water supply temperature is increased after mixing until the room temperature reaches the set temperature.

[0033] As an optional implementation, it also includes a host computer, which is wirelessly connected to the control component 1. The control component 1 will upload the real-time collected data such as water supply temperature, return water temperature and indoor temperature, as well as the energy consumption of the circulating water pump 2 and the energy consumption of the ejector 9 to the host computer, thereby realizing real-time collection of data of the entire heating system. The host computer can also upload the room set temperature to the control component 1, thereby realizing intelligent control of the heating room temperature and avoiding energy waste due to excessively high room temperature.

[0034] The utility model can be installed at the entrance of a building to achieve precise control of the average indoor temperature of the entire building, or installed in the main system pipeline of each floor of the building to achieve precise control of the average indoor temperature of the rooms in a single-story building, or installed in each room to achieve precise control of the temperature of a single room; it adopts a mixed water design and has an independent circulating water pump. The water supply temperature can be adjusted in real time according to the indoor set temperature by using the mixed water ratio to ensure the constant indoor heating temperature of the building. At the same time, the utility model device adopts an independent circulating water pump with a constant water flow, avoiding flow fluctuations, especially hydraulic imbalance caused by reduced flow. The control component 1 has a data acquisition and output interface, which can record the indoor temperature, system supply and return water temperature, and heat consumption in real time and upload them to the centralized control center.

[0035] The utility model belongs to an intelligent heating and cooling precision control terminal, which can collect data such as room temperature, supply and recovery temperature in real time to provide accurate data for the overall heating and cooling system.

[0036] The utility model adopts two electric regulating valves to adjust the mixed water volume in proportion, thereby achieving accurate control of the water temperature according to the indoor temperature, achieving no waste of heat energy and ensuring the heating temperature at the same time.

[0037] The control component 1 of the utility model has the functions of data collection, analysis and control. The utility model can be connected to the intelligent building network for control to realize intelligent control of room temperature.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
