Technical Field

[0001] The utility model relates to the field of intelligent building engineering, in particular to a building type heat, electricity and cooling combined supply and regulation system. Background Art

[0002] In traditional buildings, electricity, heating and cooling are supplied by independent supply facilities, such as electricity from the city electricity supply, heating from the city heating supply, and hot water and cooling from household water heaters and air conditioners. These methods have the problems of high energy supply costs and low energy utilization. To solve this problem, a building-type combined heat, power and cooling system is proposed.

[0003] Existing building-based combined heat, power and cooling systems are usually equipped with energy storage equipment in the load building, which is used to store electrical energy, thermal energy or cold energy so as to provide corresponding energy in different seasons.

[0004] However, existing building-based combined heat, power and cooling systems mostly directly deliver hot water, heating or cooling air to various user units (also known as load units) on the floor. In higher floors, due to factors such as pipeline settings, pipeline insulation protection and pumping device configuration, it is easy to cause uneven energy distribution, resulting in energy waste and insufficient energy conservation and environmental protection.

The heat storage module 11 transfers heat energy to a plurality of heat-consuming loads through a heat transfer fluid, and the cold storage module 12 transfers cold energy to a plurality of cold-consuming loads through a cold transfer fluid.

[0025] The first temperature measurement module 14 is disposed in the flow path of the heat transfer fluid (ie, the pipe 13a disposed on the floor 2) and is configured to obtain a plurality of first temperature data in the flow path of the heat transfer fluid (ie, the pipe 13a disposed on the floor 2).

[0026] The second temperature measurement module 16 is disposed in the flow path of the cold transfer fluid (ie, the pipe 13b disposed on the floor 2) and is configured to obtain a plurality of second temperature data in the flow path of the cold transfer fluid (ie, the pipe 13b disposed on the floor 2).

[0029] In some examples, heating loads and cooling loads may be collectively referred to as load units.

[0030] In some examples, such as Figure 3 As shown, the first temperature measurement module 14 includes a plurality of temperature sensors, and the plurality of temperature sensors are arranged at a plurality of different positions in the flow path of the heat transfer fluid, specifically, for example, in the total flow path of the heat transfer fluid in floor 2 (such as Figure 2 The total flow path can include Figure 3 The pipe positions a1 to an), the branch flow paths of the heat transfer fluid in each floor (such as Figure 2 Branches 1 to N may include Figure 3 The pipe positions b1 to bn in each floor, and the branch flow paths of the heat transfer fluid in each load unit on each floor (such as Figure 2 Subdivision 1 and subdivision 2 may include Figure 3 In the pipeline positions c1 to cn), each of them can be provided with a temperature sensor. In this case, the temperature of the heat transfer fluid at different positions of the flow path can be obtained.

[0031] In some examples, such as Figure 3 As shown, the first flow control module 15 includes a controller 560 and flow valves 561 electrically connected to the controller 560 and arranged at multiple positions, specifically, for example, in the total flow path of the heat transfer fluid in floor 2 (such as Figure 2 The total flow path can include Figure 3 The pipe positions a1 to an), the branch flow paths of the heat transfer fluid in each floor (such as Figure 2 Branches 1 to N may include Figure 3 The pipe positions b1 to bn in each floor, and the branch flow paths of the heat transfer fluid in each load unit on each floor (such as Figure 2 Subdivision 1 and subdivision 2 may include Figure 3 The positions c1 to cn in the middle pipeline can all be provided with flow valves 561, and the controller 560 controls the working state of the flow valves 561 based on the first temperature data to adjust the flow of the heat transfer fluid.

[0033] In some examples, such as Figure 3 As shown, the second flow control module 17 includes a controller 560 and flow valves 561 electrically connected to the controller 560 and arranged at multiple positions.
