The method uses a pressure sensor to convert the pressure signal taken from the constant pressure point of the system into a (4 ~ 20) Ma current signal, which is transmitted to a pressure regulator, which compares it with a pre-set pressure value and sends a frequency instruction to the converter, frequency converter automatically adjust the pump motor speed, and then adjust the amount of water, due to the liquid incompressible characteristics, the liquid pressure control response speed is fast, it is easy to maintain the constant pressure point in the set value. In Heating System, water is the carrier of heat energy, and the transmission of heat energy depends on the flow of water. The higher the water temperature, the higher the heat content of the unit water, the greater the flow of water, the greater the heat transfer. In order to balance the heat of the whole heating network, frequency conversion speed regulation technology is used to regulate the flow of the circulating pump, which can ensure the safe operation of the heating system under the condition of stable pressure. Firstly, according to the principle of low outlet temperature, small outlet temperature difference and operating regulation formula, the outlet temperature of the system is adjusted according to the change of ambient air temperature. At the same time, according to the return water temperature difference to adjust the speed of the circulation pump, so that through regulating the flow of the system to indirectly adjust the temperature. This is done by using a temperature sensor to convert the change in temperature at the sampling point into a corresponding value of voltage or current
