Alternatively, the shape of the mixing member 32 is not limited, and for example, the mixing member 32 is cylindrical, or a rectangular box.

In some embodiments, the multi-energy combined heat and power system 100 further includes a controller (not shown in the drawings), which is electrically connected to the heat supply assembly 21, the opening adjustment part 34, the detection assembly, and the heat utilization terminal 1, and controls the opening adjustment part 34 to adjust the opening of the heat medium channel 310 according to information provided by the detection assembly, so that the heat mediums provided by the plurality of heat supply assemblies 21 are adjusted to a preset temperature in the mixing chamber.

For example, after the heating media are hot water and the numerical information provided by the detection component is obtained by the controller, if the mixing cavity has no hot water, the controller performs the following formula: mixing chamber outlet 322 temperature t2= (t11×m11+t12×m12 … … T1n×m1N)/M2, where M2 is the sum of M11 to M1N, after each heating element 21 is controlled by the controller to heat the heating medium to the corresponding temperature, the heating medium with the corresponding mass is then fed into the mixing chamber by the adjusting element 31.

If there is hot water in the mixing chamber, the mass of the hot water in the mixing chamber is denoted as M0, and the temperature of the hot water is denoted as T0, at which time the formula is based on: mixing chamber outlet 322 temperature t2= (t0×m0+t11×m11+t12×m12 … … T1n×m1N)/m2+m0, where M2 is the sum of M11 to M1N. After each heating module 21 is controlled by the controller to heat the heating medium to the corresponding temperature, the heating medium with the corresponding mass is sent into the mixing cavity by the adjusting module 31.

The heat utilization terminal 1 is provided with a control panel on which a user can select the desired water temperature and water quantity to be used. The technical scheme of the utility model is briefly described below by taking the example that no hot water exists in the mixing cavity. For example, there are 3 heating units 21, where the temperature t2= (t11×m11+t12×m12+t13×m13)/M2 of the mixing chamber outlet 322, the user inputs a preset temperature, for example 40 degrees, with the thermal terminal 1, and selects 10L, where the controller sets M2 to 10L, the first temperature sensor detects that the values of T11, T12, and T13 are 20 degrees, 30 degrees, and 50 degrees, respectively, and since the water temperature has little influence on the water density, after the density counteracts in the formula, the controller solves the calculation formula: 40 = (20×m11+30×m12+50×m13)/10, solving to obtain a plurality of groups, for example,

a first group: m11=7; m12=7; m13=1;

second group: m11=6; m12=6; m13=2;

third group: m11=5; m12=5; m13=3;

……

the controller may choose any one of the sets of solutions to regulate the regulating members 31, or choose according to the reserves of heating medium in each heating member 21, or the controller chooses a set of solutions that minimize the consumption of conventional energy to regulate the regulating members 31, thereby reducing the consumption of conventional energy.

It should be noted that, if the values of T11, T12, and T13 do not reach the preset values set by the user, the controller controls one or more heating assemblies 21 to heat the heating medium therein, and when the temperature of the heating medium in one of the heating assemblies 21 exceeds the preset value set by the user by 5 degrees or 10 degrees, the controller controls the heating assembly 21 to stop heating. If the heat medium reserve in the heat supply assembly 21 does not reach the preset value of the user, the controller controls the corresponding water pump to pump water into the heat supply assembly 21, and when the water quantity exceeds 5L or 10L of the preset water quantity, the water pump is stopped and the heat supply assembly 21 is controlled to heat. In practice, there are various situations, and for each situation, a corresponding program may be preset in the controller, which will not be described herein.

When the regulating assembly 31 stops operating, the opening of the heating medium channel 310 is regulated to the minimum, and at this time, the heating medium channel 310 is disconnected from the heating assembly 21 and the mixing chamber. When the regulating members 31 are operated, the heating medium channels 310 are communicated with the heating members 21 and the mixing chamber, and the opening degree of the heating medium channels 310 is correspondingly regulated according to the mass of the hot water provided by each heating member 21. The more heating assemblies 21 that provide hot water, the greater the opening of the corresponding heating medium channel 310. When the value detected by the first mass sensor is close to the target value, the opening of the heat medium adjusting channel 310 is gradually reduced, and when the value detected by the first mass sensor is the target value, the opening of the heat medium adjusting channel 310 is reduced to the minimum, namely, the heat medium adjusting channel 310 is disconnected from the mixing cavity inlet 321.

Optionally, in other embodiments, on-off valves are provided at each of the mixing chamber inlet 321 and mixing chamber outlet 322. Therefore, the control of the heating medium in the pipeline can be further enhanced.
