【Abstract】 In the heating system, there is a deviation between the actual operating conditions of the variable frequency water pump and the theoretical characteristic values, resulting in low overall operating efficiency. However, the existing system lacks the function of automatically calculating the operating efficiency, which makes it difficult to timely analyze and handle energy consumption according to the efficiency situation, resulting in high overall energy consumption of the system. By establishing a mathematical model for water pump operation, developing PLC programs, and collecting real-time operational data, intelligent calculations can be achieved. The test results show that the system can promptly handle the poor operation of the water pump, and overall improve management efficiency and economic benefits.更多还原
