Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] Combined with Figure 1 , according to an embodiment of the present invention, a system for energy consumption assessment of a secondary water supply pressurization and storage device is provided, including: a simulated building erected on a test site.

[0031] The simulated building of the present invention refers to a building model erected on a test site, rather than an actual building (such as a residence, a building, etc.).

[0032] Such as Figure 1As shown in the figure, the simulated building constructed by the utility model includes multiple simulated layers. In this embodiment, the multiple simulated layers are respectively the bottom simulated layer 1F, the second simulated layer 2F, the third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF.

[0033] A water pool 1 is arranged on the bottom simulated layer 1F of the simulated building. The water pool 1 is connected to the main inlet pipe 8, and the main inlet pipe 8 is connected to the vertical main pipe 8'. The vertical main pipe 8' extends along the height direction of the simulated building to each simulated layer of the simulated building (the bottom simulated layer 1F, the second simulated layer 2F, the third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF).

[0034] The height direction of the utility model refers to the direction in which the simulated building extends vertically into the air from the ground of the test site where the simulated building is constructed.

[0035] According to the embodiment of the utility model, on each simulated layer (the second simulated layer 2F, the third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF) between the second simulated layer 2F and the top simulated layer NF of the simulated building, the vertical main pipe 8' is connected to the simulated layer branch pipe 13. In the following embodiments, the second simulated layer 2F will be taken as an example for illustration. The third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF are the same as the second simulated layer 2F and will not be elaborated hereinafter.

[0036] According to the embodiment of the utility model, a system for evaluating the energy consumption of a secondary water supply pressurization and storage device further includes: a drain pipe 17. The drain pipe 17 extends along the height direction of the simulated building to each simulated layer of the simulated building (the bottom simulated layer 1F, the second simulated layer 2F, the third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF).

[0037] On each simulated layer (the second simulated layer 2F, the third simulated layer 3F, the fourth simulated layer 4F, ……, the top simulated layer NF) between the second simulated layer 2F and the top simulated layer NF of the simulated building, the simulated layer branch pipe 13 is connected to the drain pipe 17.

[0038] Furthermore, on the top simulated layer NF of the simulated building, an exhaust valve 14 is installed on the vertical main pipe 8'. On the top simulated layer NF of the simulated building, a vent cap 15 is installed on the drain pipe 17. On the bottom simulated layer 1F of the simulated building, the drain pipe 17 is connected to the water pool 1 to return the water in the test process to the water pool through the drain pipe 17, avoiding water waste.

[0039] Further, on each simulation layer of the simulated building (the bottom layer simulation layer 1F, the second layer simulation layer 2F, the third layer simulation layer 3F, the fourth layer simulation layer 4F, ……, the top layer simulation layer NF), an adjustable main pipe pressure reducing valve 9 is installed on the vertical main pipe 8'.

[0040] The water supply pressure of the vertical main pipe 8' is adjusted by the adjustable main pipe pressure reducing valve 9, so as to simulate the water supply pressure of buildings with different floor heights (such as residences, buildings, etc.), save the height between the multiple simulation layers of the built simulated building, and save the installation space of the vertical main pipe 8'.

[0041] According to an embodiment of the present invention, on the bottom layer simulation layer 1F of the simulated building, a test pump 2, a pressure gauge 5 and a remote transmission water meter 6 are installed on the water inlet main pipe 8. The test pump 2 is used to simulate the booster pump of the secondary water supply pressurization and storage equipment, and evaluate the energy consumption of the booster pump of the secondary water supply pressurization and storage equipment.

[0042] Further, on the bottom layer simulation layer 1F of the simulated building, an air pressure tank 4 is also installed on the water inlet main pipe 8, and the air pressure tank 4 is arranged between the test pump 2 and the pressure gauge 5. The air pressure tank 4 is used to stabilize the overall water supply pressure of a system for evaluating the energy consumption of a secondary water supply pressurization and storage equipment of the present invention.

[0043] The pressure gauge 5 is used to collect the total water supply pressure of the water inlet main pipe 8. The remote transmission water meter 6 is used to collect the total water supply volume of the water inlet main pipe 8.

[0044] Further, a system for evaluating the energy consumption of a secondary water supply pressurization and storage equipment of the present invention further includes: a control system 3 provided on the bottom layer simulation layer 1F of the simulated building. The control system 3 is electrically connected to the test pump 2, and the control system 3 is electrically connected to the pressure gauge 5.

[0045] The control system 3 adjusts the frequency of the test pump 2 according to the total water supply pressure of the water inlet main pipe 8 (the total water supply pressure of the water inlet main pipe 8 collected by the pressure gauge 5), and adjusts the total water supply pressure of the water inlet main pipe 8.

[0046] Further, on the bottom layer simulation layer 1F of the simulated building, a water inlet main pipe electric control valve 7 is also installed on the water inlet main pipe 8, which is used to open or close the water inlet main pipe 8.

[0047] According to an embodiment of the present utility model, on each simulation layer (the second simulation layer 2F, the third simulation layer 3F, the fourth simulation layer 4F, ……, the top simulation layer NF) between the second simulation layer 2F and the top simulation layer NF of the simulated building, an adjustable branch pressure reducing valve 10, a branch electric control valve 11, and an electromagnetic flowmeter 12 are sequentially installed on the simulation layer branch pipe 13. The adjustable branch pressure reducing valve 10 is used to adjust the water supply pressure under different working conditions of the corresponding simulation layer, simulating the water supply pressure of the actual building floor. The electromagnetic flowmeter 12 is used to count the water supply volume under different working conditions of the corresponding simulation layer, simulating the water supply volume of the actual building floor.

[0048] Figure 1 Exemplarily, taking the second simulation layer 2F as an example, through the adjustable branch pressure reducing valve 10, the water supply pressure under different working conditions of the corresponding second simulation layer 2F is adjusted to simulate the water supply pressure of the actual building floor. Through the electromagnetic flowmeter 12, the water supply volume under different working conditions of the corresponding second simulation layer 2F is counted to simulate the water supply volume of the actual building floor.

[0049] On each simulation layer (the second simulation layer 2F, the third simulation layer 3F, the fourth simulation layer 4F, ……, the top simulation layer NF) between the second simulation layer and the top simulation layer of the simulated building, a drain hopper 16 is also installed on the simulation layer branch pipe 13, and the drain hopper 16 is connected to a drain pipe 17. During the test process, the water on each simulation layer (the second simulation layer 2F, the third simulation layer 3F, the fourth simulation layer 4F, ……, the top simulation layer NF) between the second simulation layer and the top simulation layer of the simulated building returns to the water tank 1 through the drain hopper 16 and the drain pipe 17.

[0050] According to an embodiment of the present utility model, a method for evaluating the energy consumption of a secondary water supply pressurization and storage device uses a system for evaluating the energy consumption of a secondary water supply pressurization and storage device provided by the present utility model to evaluate the energy consumption of the secondary water supply pressurization and storage device.

[0051] Specifically, at the start of the energy consumption test evaluation, the main inlet pipe electric control valve 7 is opened, and the water in the water tank 1 is pumped into the main inlet pipe 8 through the test pump 2 to supply water to the entire system, and the pressure stabilizing tank 4 stabilizes the overall water supply pressure of the system.

[0052] By adjusting the opening degree of the adjustable main pipe pressure reducing valve 9, the water supply pressure of the vertical main pipe 8' is adjusted, so as to simulate the water supply pressure of buildings with different floor heights (such as residential buildings, high-rise buildings, etc.).

[0053] For example, by adjusting the opening degree of the adjustable main pipe pressure reducing valve 9, the water supply pressure of the vertical main pipe 8' is adjusted to simulate the water supply pressure between floors of residential buildings. For another example, by adjusting the opening degree of the adjustable main pipe pressure reducing valve 9, the water supply pressure of the vertical main pipe 8' is adjusted to simulate the water supply pressure between floors of high-rise buildings.

[0054] Open the branch pipe electric control valves 11 of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building to supply water to each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building.

[0055] By adjusting the opening degree of the adjustable branch pipe pressure reducing valve 10 of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building, the water supply pressure under different working conditions of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) is adjusted.

[0056] Through the electromagnetic flowmeter 12 of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building, the water supply volume under different working conditions of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) is counted.

[0057] When collecting the water supply total pressure of the inlet main pipe 8 under different working conditions of the water supply pressure of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building through the pressure gauge 5.

[0058] When collecting the total water supply volume of the inlet main pipe 8 under different working conditions of the water supply volume of each simulated floor (the second simulated floor 2F, the third simulated floor 3F, the fourth simulated floor 4F,..., the top simulated floor NF) between the second simulated floor 2F and the top simulated floor NF of the simulated building through the remote transmission water meter 6.

[0059] The water supply total pressure of the inlet main pipe 8 collected by the pressure gauge 5 is fed back to the control system 3. The control system 3 adjusts the frequency of the test pump 2 according to the water supply total pressure of the inlet main pipe 8 to adjust the water supply total pressure of the inlet main pipe 8.

[0060] Evaluate the energy consumption of the test pump 2 based on the total water supply pressure of the main water inlet pipe 8 and the total water supply volume of the main water inlet pipe 8.

[0061] A system for evaluating the energy consumption of a secondary water supply pressurization and storage device provided by the present utility model can conduct test experiments on the energy consumption of the secondary water supply pressurization and storage device under different working conditions of water supply volume - pressure, quantitatively study the variation of the energy consumption of the booster pump of the secondary water supply pressurization and storage device under different water supply volumes and different pressures, evaluate the energy consumption control effect of pressure management, determine the optimal pressure control range under different application scenarios, and provide a basis for building energy conservation and consumption reduction.

[0062] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
