What are the control methods of the plate heat exchanger unit

  The plate heat exchanger unit is a combination of pump, heat exchanger, valve, sensor and control module. It is used to meet certain needs of What are the control methods of the plate heat exchanger unittemperature and pressure. What are the control methods of the plate heat exchanger unit?

(1) Temperature control (T). The plate-type unit guarantees constant water temperature on the secondary side by adjusting the flow on the primary side, which can generally save 30% of the heat source. Pumpheat's unique dual frequency conversion technology, one pump frequency conversion can save 50% of the power of one pump. Outdoor temperature compensation. When the outdoor temperature is higher than the set degree Celsius, the secondary water temperature can be corrected according to user needs.

(2) Variable pressure difference control (P)

The plate heat exchanger unit adopts Pumpheat secondary frequency conversion technology, variable pressure differential control of the circulating pump, and the differential pressure sensor is installed at the most disadvantageous point. Therefore, the circulating pump is controlled by frequency conversion according to the working conditions, which meets the requirements of the variable pressure differential of the system and achieves energy saving of 50 %.

(3) Voltage regulation control (J)

The plate heat exchanger unit has a low-pressure protection function. When the secondary side return water pressure does not reach the low limit protection value, the circulation pump automatically stops running, and the electric regulating valve is closed, and the automatic make-up pump runs.
