[0019] In a first aspect, the present application provides a method for managing equipment for zero-emission energy saving in industrial and mining enterprises. Figure 1 The specific steps included in the method are as follows.

[0020] Step S110: Acquire enterprise workshop information data and equipment basic information data; the enterprise workshop information data includes workshop device type, workshop device location and workshop device preset importance data; the equipment basic information data includes equipment type, equipment cost and equipment performance.

[0021] It can be understood that in this solution, the equipment with energy absorption function can be a heat pump, and the specific application scenario is to arrange a heat pump in the company's workshop and use the heat pump to absorb the heat emitted by the equipment in the workshop; specifically, the heat pump has two working modes; the summer working mode is that the heat pump switches to cooling mode, and the heat dissipation of the recovery equipment is used for workshop cooling, and the condensation heat is stored for use in other processes; the winter working mode is the heat pump heating mode, using waste heat for heating.

[0022] It should be noted that the preset importance data of the workshop devices here is determined based on the working frequency of the workshop devices. Multiple historical time periods of the same length are selected to determine the working frequency of each workshop device in each historical time period. The working frequency is obtained by dividing the number of device startups by the length of the historical time period; then the sum of the working frequencies of the devices corresponding to each historical time period is calculated, and then the sum is divided by the number of historical time periods to obtain the average working frequency; the preset importance data of each device is obtained based on the average working frequency and the preset frequency comparison table; the preset frequency comparison table here includes the correspondence between the average working frequency and the preset importance data.

[0023] It can be understood that the equipment performance here refers to the number of devices that the heat pump can connect to. When the heat pump is arranged in each enterprise workshop, based on the heat pump function, the purpose of using the heat pump is to recover the heat emitted by the workshop equipment and achieve the purpose of waste heat recovery. Therefore, the heat pump needs to be arranged near the workshop equipment so that the heat pump can cover the connected equipment and be close to the equipment, which can improve the waste heat recovery efficiency of the heat pump.

[0030] Furthermore, the cost performance data of the solution is calculated as follows: cost performance data of the solution = equipment function value data / equipment layout cost data.

[0031] Step S140: outputting scheme recommendation information based on the scheme cost performance data; the scheme recommendation information includes a workshop equipment layout scheme having the highest scheme cost performance data.
