A good plate heat exchanger unit, low noise, stable pump operation, improved the environment of the machine room. If the configuration of the heat exchanger unit is flexible, it can be scientifically and reasonably optimized according to the different needs of the user, so that the customer's demand can be met to a large extent.
(1)Secondary side supply and return water pressure difference control and secondary side return water pressure control.
(2)Backwater temperature limit, heat flow (water flow) limit, backwater temperature difference limit and scale detection.
(3) Use an electric control valve to control the flow rate of the primary network so that the outlet of the secondary network maintains the set temperature. The flow rate of the primary network is controlled by a self-standing temperature regulating valve, so that the outlet of the secondary network maintains the set temperature. The outlet temperature of the secondary network is automatically adjusted according to the outdoor temperature.
(4)The controller of the plate heat exchanger unit has a standard 485 communication interface. In the active and passive mode, the controller can collect the controller parameters of the power station through the next wheel patrol, and upload it when the controller alarms.
(5) Frequency conversion water, use the pressure signal of the secondary network backwater to control the output of the inverter, to achieve automatic water replenishment, so that the system maintains constant pressure. With the electrical control of the electric contact pressure gauge, the secondary network system is used to control the start and stop of the make-up pump compared with the upper and lower limits of previous years, so that the system maintains a constant pressure.
(6)The function of the control zone of the plate heat exchanger unit is determined according to the actual situation of the heat exchange station, and can be unattended.
