Specifically, a plurality of total cooling capacity ranges may be predetermined, and the types of the chiller units and the number of the chiller units of each type may be determined according to the total capacity range to which the total cooling capacity belongs, for example: the total cold quantity is less than 600RT, and 2 cold water units with the same type are adopted; the total cold quantity is less than or equal to 1050RT after 600RT, and 3 cold water units with the same type are adopted; 1050RT < the total cold quantity is less than or equal to 1600RT, and a combination of 2 large machines and 1 small machine is adopted (the large machine refers to a water chiller with larger cold quantity, and the small machine refers to a water chiller with smaller cold quantity); 1600RT < the total cold quantity is less than or equal to 2900RT, two schemes are adopted and divided into: 2 big machines and 1 small machine combination or 3 big machines and 1 small machine combination; 2900RT < total cold quantity is less than or equal to 5200RT, and a combination of 3 big machines and 2 small machines is adopted.
In this embodiment, the same chiller of the type or two chillers with different coldness may be used for setting, for example: determining a first number of chiller units of a first type based on the total refrigeration capacity; wherein the first quantity is determined based on the following equation: x is A1×B1(ii) a Wherein X is the total cold quantity; a. the1Is a first quantity, B1The cold quantity of the first type of water chilling unit;
for example: if the total cold quantity is 500RT, 2 cold water units with the cold quantity of 250RT can be adopted; the total cold quantity is 600RT, 2 cold water units with the cold quantity of 300RT can be adopted; and the total cooling capacity is 750RT, 3 cold water units with the cooling capacity of 250RT can be adopted.
Or, determining a second number of the cold water units of the second type and a third number of the cold water units of the third type based on the total refrigeration capacity; wherein the second number and the third number are determined based on the following equation: x is A2×B2+A3×B3(ii) a Wherein X is the total cold quantity; a. the2Is a second number, B2The cold quantity of the second type of water chilling unit; a. the3Is a third number, B3The cold capacity of the third type of chiller.
For example: if the total cold quantity is 1150RT, 2 cold quantity water chilling units with the cold quantity of 450RT and 1 cold quantity water chilling unit with the cold quantity of 250RT can be adopted; the total cold quantity is 1250RT, 2 cold water units with the cold quantity of 500RT and 1 cold water unit with the cold quantity of 250RT can be adopted; the total cold quantity is 2950RT, 3 cold water units with the cold quantity of 750RT and 1 cold water unit with the cold quantity of 350RT can be adopted.
In this embodiment, when performing model selection, the major machines are considered preferentially, even if the number of major machines is greater than the number of minor machines, for example: the second number is greater than or equal to the third number; the cold capacity of the second type of cold water unit is greater than the cold capacity of the third type of cold water unit.
The cold quantity of the second type of water chilling unit is larger than that of the third type of water chilling unit, so that the second type of water chilling unit is a large machine, and the third type of water chilling unit is a small machine. The second number is the number of big machines, the third number is the number of little machines, and the number of big machines is greater than the number of little machines.
And S206, determining the model selection parameters of the water pump and the cooling tower based on the model selection information and the model selection parameters of the water chilling unit.
The model selection parameters of the water pump in the embodiment comprise the flow, the lift, the motor power and the number of the water pump, and can be determined through the following steps: determining the flow rate of the water pump based on the temperature working condition and the type of the water chilling unit; determining the lift of the water pump based on the total cold quantity; determining the motor power of the water pump based on the flow, the lift and the pre-acquired efficiency of the water pump; the number of water pumps is determined based on the number of each type of chiller.
Specifically, the water pump of the embodiment comprises a chilled water pump and a cooling water pump, and the temperature working condition comprises a first temperature difference and a second temperature difference; wherein, the first temperature difference is the difference between the supply temperature of the chilled water and the return temperature of the chilled water; the second temperature difference is the difference between the supply temperature of the cooling water and the return temperature of the cooling water. Based on the above description, the flow rate of the water pump can be calculated by: determining the cold quantity of each type of water chilling unit; determining the flow rate of the chilled water pump based on the first temperature difference and the cold quantity of each type of water chilling unit; and determining the flow rate of the cooling water pump based on the second temperature difference and the cold quantity of each type of water chilling unit.
In general, the first temperature difference and the second temperature difference may be 5 ℃, 6 ℃, 7 ℃, etc., and the flow rate of the chilled water pump may be calculated by the following equation: the flow Q of the chilled water pump is 3600 × the cold energy of the water chilling unit/(4200 × the first temperature difference). The flow rate of the cooling water pump can be calculated by the following equation: the flow Q of the cooling water pump is 1.25 × 3600 × the cold capacity of the chiller/(4200 × the second temperature difference).
The lift of freezing water pump and cooling water pump all can divide according to total cold volume, for example: the delivery lift of the chilled water pump: the total cold quantity is less than or equal to 1050RT, and the lift is 26 m; 1050RT < the total cold quantity is less than or equal to 2600RT, and the lift is 28 m; 2600RT < total cold quantity is less than or equal to 4150RT, lift is 30 m; 4150RT < total cold quantity is less than or equal to 5200RT, and the lift is 32 m.

The motor power of the water pump can be calculated by the following formula: p ═ G · H/(323 × η), where: p is the motor power of the water pump; g is the flow rate of the water pump, and the unit can also be m3H; h is the lift of the water pump, and the unit can be mH2O; η is the pre-acquired efficiency of the water pump, typically between 78% and 88%.
The number of the freezing water pumps and the cooling water pumps corresponds to the number of the water chilling units, for example: the water chilling unit comprises 3 water chillers, and the freezing water pump and the cooling water pump are 3.
The selection parameters of the cooling towers comprise the number of the cooling towers, water quantity and motor power, and can be determined by the following steps: determining the number of cooling towers based on the number of the water chilling units of each type; determining the water quantity of the cooling tower based on the total cooling capacity and the number of the cooling towers; wherein, the product of the water quantity and the quantity of the cooling tower is equal to the total cold quantity; the motor power of the cooling tower is determined based on the water amount of the cooling tower.
The number of the cooling towers can be calculated according to the type and the number of the water chilling units, and if the water chilling units are the same in type and the number is X, the number of the cooling towers can also be X; if the water chilling unit comprises Y large units and Z small units, the number of the cooling towers can be 2X + Z units. The water amount of the cooling tower can be calculated by the following formula; a is b/c; wherein a is the water quantity of the cooling tower, b is the total cooling capacity, and c is the number of the cooling towers. The total cooling capacity can also be calculated in the following way: b ═ di×ei；diNumber of water coolers of i-th type, eiThe cooling capacity of the water chiller of the ith type.
After the step of determining the model selection parameters of the chiller, the water pump and the cooling tower, the dimensions of the various pipes of the air-conditioning room may also be determined, for example: and determining the size of the pipeline of the air conditioner room based on the model selection parameters of the water chilling unit, the water pump and the cooling tower.
Wherein, can calculate the flow of each pipeline earlier, then calculate each branch pipe way and main pipeline pipe diameter.
In this embodiment, a correspondence between the pipe size and the model selection parameter of each device may be obtained in advance, and a suitable pipe size may be selected according to the correspondence. For example: the pipelines of the air conditioner room can comprise a freezing branch pipe, a cooling tower inlet and outlet pipeline, a freezing main pipe, a cooling main pipe and the like. If the cold quantity of the water chilling unit is less than or equal to 300RT, the diameter of the freezing branch pipe can be 200 mm; if the cold capacity of the water chilling unit is more than 300RT and less than or equal to 450RT, the diameter of the freezing branch pipe can be 250 mm; if the water amount of the cooling tower is more than 230m3H is aAnd is not more than 345m3And/h, the diameter of the inlet and outlet pipeline of the cooling tower can be 250 mm.
And S208, determining the model selection parameters of the sensor and the controller based on the model selection parameters of the water chilling unit, the water pump and the cooling tower.
The model selection of the sensors and the controller, namely the model selection of the control system, can calculate the types and the number of the matched sensors and the configuration of the controller and the control cabinet according to the model selection parameters of each device. For example: determining the model selection parameters of a sensor and a controller which are matched with the model selection parameters of the water chilling unit, the water pump and the cooling tower; the model selection parameters of the sensors and the controllers comprise the models and the numbers of the sensors and the controllers.
Specifically, the control system configuration principle may be: when the main machine (i.e. water chiller) N is used and the tower Q is cooled: the temperature sensors are 4: the freezing water supply and return main pipe is 2, and the cooling water supply and return main pipe is 2. The pressure sensor is 2: the freezing water supply and return main pipes are 2. Outdoor temperature and humidity sensor is 1: the number of the cooling tower roofs is 1. N +2 heat meters: the main machine comprises N freezing branch pipes, 1 freezing main pipe and 1 cooling main pipe. Electric butterfly valve: q x 2 (the main machine does not need to be provided with an electric valve).
