Description

Technical Field

[0001] The utility model belongs to the field of building water supply, and in particular relates to a water supply system for a type of high-rise building. Background Art

[0002] A type of high-rise building, with functional areas including hotels, offices and some commercial areas, currently faces the following technical problems: 1. The water supply system in the hotel functional area is relatively complex, with water usage occurring at various times. The kitchen consumes a large amount of water, and the kitchen design flow rate is calculated to be 15L / S. The bathroom design flow rate is calculated to be 4.28L / S based on the hotel function, with an average hourly flow rate of 3.78L / S. If the kitchen water consumption and the average hourly flow rate of the bathroom are added together as the design water consumption for the area, the water consumption will not differ much. In addition, the hotel's water usage is relatively concentrated during the hours, and there is a high possibility that water consumption peaks will occur together. 2. Given the complexity of the functions of each area, how can we ensure stable water pressure and eliminate water use problems caused by uneven water pressure? Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems in the prior art and to provide a water supply system with a partitioned design and capable of dynamic water supply management.

[0005] The source water pool is connected to the clean water pool through pipelines and purification and disinfection equipment. The clean water pool is supplied to each partition of the high-rise building through three sets of variable frequency water supply equipment: high, medium and low;

[0006] The constant frequency pump group is connected to the cooling water inlet of the air conditioner and the water supply inlet of the swimming pool through a pipeline.

[0007] Preferably, the water supply equipment on the first and second floors of the high-rise building is connected to the municipal water supply interface, and the remaining floors are supplied with water by a set of variable frequency water supply equipment and a domestic water tank combination. The air-conditioning cooling tower water supply tank installed on the roof of the high-rise building is shared with the domestic water tank, and the constant frequency pump group supplies cooling tower water supply.

[0008] Preferably, the first water supply pump room is provided with a source water pool composed of several interconnected source water tanks and a clean water pool composed of several interconnected clean water tanks. The clean water tanks are each provided with a water tank self-cleaning disinfector. The source water tank and the clean water tank are connected through a clean water circulation pump, pipes and valves. The clean water tanks are respectively connected to the low-area domestic frequency conversion pump, the middle-area domestic frequency conversion pump and the high-area domestic frequency conversion pump through pipes. The low-area domestic frequency conversion pump, the middle-area domestic frequency conversion pump and the high-area domestic frequency conversion pump are respectively connected to the low-area water supply pipe, the middle-area water supply pipe and the high-area water supply pipe.

[0009] Preferably, an air-conditioning cooling water tank and a domestic water tank are provided in the second water supply pump room. The air-conditioning cooling water tank is connected to the air-conditioning cooling water supply pipe through a constant frequency pump group. The domestic water tank is provided with two water outlets. The first water outlet is connected to the first and second floor water supply pipes of the high-rise building through a variable frequency pump group, and the second water outlet is connected to the air-conditioning cooling water supply pipe through a constant frequency pump group.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The utility model realizes zoned water supply through at least two independent water supply pump rooms. The utility model can better control and manage the water pressure and water consumption of each area, avoid insufficient water pressure during peak water use, and improve water supply stability;

[0012] 2. Air conditioning cooling water replenishment and swimming pool water replenishment are driven by constant frequency pump groups, and the water supply to each functional area is driven by multiple variable frequency pump groups, which dynamically adjust the water supply volume and optimize the water supply efficiency to fully meet the complex water needs of hotels, offices and commercial areas.
