An article on 'industrial cold water machine the calculation method of the cold (
1)
Has taught you how to calculate the cold industrial cold water machine, the following said, host selection, water tower, water pump, etc.
calculate the cooling capacity according to the requirement, control unit sample data selection, for example:
calculate the cold quantity is 100000 calories, choose water cooled screw unit, can choose TFSB - reference sample data
115 ws, can be learned from the sample: condenser water flow for 28 m3 / h, evaporator water flow for 23 m3 / h.
A, choose the cooling tower, according to the flow of condenser 1 unit.
2 to 1.
Three times
B, choose the cooling water pump, according to the flow of condenser 1 unit.
2 to 1.
Three times, tong Chang Yangcheng take 20 m, it is suggested that the head is designed according to the actual situation;
C, choose frozen water pump, according to the flow rate of 1 unit evaporator.
1 ~ 1.
Usually 2 times, head take 30 m, it is suggested that the head is designed according to the actual situation.
