The hot end is connected to the second terminal heat exchanger of a corresponding water heater, the two heat-absorbing ends of the mixing unit are respectively provided with heat-absorbing valves, and the heat-releasing end of the mixing unit is provided with a heat-releasing valve.

FIG. 2 shows an optional embodiment of the control method of the above energy system.

In this optional embodiment, the control method for controlling the above-mentioned energy system includes the following steps: Step 11, according to the target temperature of the water heater, control two heat absorption valves of the mixing unit connected to the second terminal heat exchanger of the water heater opening time. Step 12, according to the difference between the target temperature and the actual temperature of the water heater, control the opening time of the heat release valve of the mixing unit connected to the second terminal heat exchanger of the water heater.

With this optional embodiment, when the heat absorption valve of the mixing unit is opened, the high temperature medium of the heat exchanger in the high temperature and the low temperature medium of the heat exchanger in the low temperature are mixed in the mixing unit, and the mixed medium is supplied to the second terminal of the water heater. The heat exchanger is used to heat the water in the water heater cavity, and the temperature of the medium in the mixing unit can be precisely adjusted by controlling the opening time of the two heat-absorbing valves. When the heat release valve of the mixing unit is closed, the second terminal heat exchanger of the water heater is cut off from the mixing unit, and the water heater stops exchanging heat.

Optionally, the energy system takes a household as a unit, or an entire unit building as a unit, or an entire community as a unit, or a certain area as a unit.

Optionally, the target temperature is a preset temperature set by the user.

The target temperature of the medium in the heater; according to the target temperature of the medium in the second terminal heat exchanger, adjust the opening time of the two heat absorption valves of the mixing unit connected to the second terminal heat exchanger of the water heater.

For example, when the temperature difference between the target temperature and the actual temperature of one of the water heaters is large, the water heater needs more heat exchange. First, according to the target temperature of the water heater, control the opening time of the two heat-absorbing valves of the mixing unit, and adjust the temperature of the medium in the mixing unit. , and then, according to the temperature difference between the target temperature and the actual temperature of the water heater, the opening time of the heat release valve of the mixing unit is controlled.

In another optional embodiment, the above control method further includes: acquiring the number of running water heaters; controlling the heat release of the mixing unit connected to the second terminal heat exchanger of the water heater according to the number of running water heaters The valve is opened in time.

With this optional embodiment, when the number of running water heaters reaches a certain value, the second terminal heat exchanger that exchanges heat with the first terminal heat exchanger is controlled by the method of time-sharing opening, that is, the second terminal heat exchanger is controlled to exchange heat with the second terminal heat exchanger.

The full-time opening of the heat release valve of the mixing unit means that the opening time of the heat release valve of the mixing unit is not limited, and it does not mean that the heat release valve of the mixing unit is always open.

With this optional embodiment, the capacity of the first terminal heat exchanger can be optimized, and more water heater work can be supplied through the first terminal heat exchanger with a smaller capacity or a smaller number. For example, the number of second terminal heat exchangers that can be supplied by the first terminal heat exchanger at the same time is 10. When the number of running water heaters is 15, in a period of time, control the heat exchange with the first terminal heat exchanger. The number of second terminal heat exchangers is 10, and the method of time-sharing opening is used to control the second terminal heat exchangers connected to the first terminal heat exchangers, so as to realize uniform heat exchange of multiple second terminal heat exchangers, so as to achieve uniform heat exchange between multiple second terminal heat exchangers. The supply of the medium in the first terminal heat exchanger is ensured, so that each water heater can evenly heat up or cool down.

Optionally, when the number of running water heaters is greater than the preset value, the switch mode of single input and single output is adopted to control the second terminal heat exchanger that is connected in and the second terminal heat exchanger that is withdrawn, and all second terminal heat exchangers are exchanged. The heat exchanger adopts the switching mode of single input and single output for circulating heat exchange.

For example, for a water heater with a large difference between the target temperature and the actual temperature, more heat exchange is required with the first terminal heat exchanger than a water heater with a small difference between the target temperature and the actual temperature. Therefore, the difference between the target temperature and the actual temperature The difference is an important basis for controlling the number of the first terminal heat exchanger connected to the second terminal heat exchanger. For example, for a water heater with a large difference between the target temperature and the actual temperature, a single water heater needs to perform more heat exchange. Therefore, the number of the first terminal heat exchanger connected to the second terminal heat exchanger of the water heater is controlled to prevent the occurrence of system Insufficient supply of media. For another example, for a water heater with a small difference between the target temperature and the actual temperature, a single water heater needs to perform less heat exchange. Therefore, the first terminal heat exchanger can be connected to the second terminal heat exchange of a larger number of the above-mentioned water heaters at the same time. device.

In another optional embodiment, the above control method further includes: controlling the discharge of the mixing unit connected to the second terminal heat exchanger of each water heater according to the number of running water heaters and the difference between the target temperature and the actual temperature of the water heaters The opening time of the thermal valve.

Optionally, when the target temperature of the water heater is higher than the actual temperature, the opening time of the heat release valve of the mixing unit connected to the second terminal heat exchanger of the water heater is controlled; when the target temperature of the water heater is lower than the actual temperature, the control and the The heat release valve of the mixing unit connected to the second end heat exchanger of the water heater is closed.

The heat release valve of the connected mixing unit is open for a long time; for a water heater with a small temperature difference between the target temperature and the actual temperature, the heat release valve of the mixing unit connected to the second terminal heat exchanger of the water heater is controlled to be open for a short time.

The fluid medium absorbs the energy generated on the side of the temperature adjustment device, and then flows to the energy absorption end 101 of the energy storage station 10. The energy storage material in the energy storage station 10 absorbs and stores the energy of the medium at the energy absorption end 101, and releases the energy.

There are many ways to communicate with each other, as long as the heat exchange device on the side of the temperature regulation equipment and the energy absorption end 101 can form a medium circulation passage. For example, as shown in FIG. 3f , a plurality of energy absorbing ends 101 are connected through the liquid inlet transfer pipeline 151 and the liquid outlet transfer pipeline 152 , and the liquid inlet pipe 141 of each energy absorbing end 101 is connected with the liquid inlet transfer pipeline 151 , the liquid outlet pipe 142 of each energy absorption end 101 is communicated with the liquid outlet transfer pipe 152 .
