Plate heat exchanger is a kind of integrated heat transfer equipment, which is controlled by plate heat exchanger, circulating pump, make-up water pump, thermometer, pressure gauge, all kinds of sensing equipment, pipeline and valve, heat exchanger and central control, district heating (cooling) adjustment machine, and can also modularize and add make-up water system, constant pressure system, water treatment system, variable frequency medium control system Only auxiliary subsystems such as calorimeter and network communication control system can form a complete plate heat exchange unit.
On the premise that the design status has been given, the selection of heat transfer coefficient, unit facilities, pipelines, valves, etc. of plate heat exchanger unit must adopt the detailed standard data of each heat exchanger unit in the technical terms. When the unit is in normal use, the fluid flow velocity in its pipeline shall not exceed 2.2m/s. Every heat exchanger for compensating heat exchange needs 15% more heat transfer area due to fouling, and its frame should retain (15%) the plate capacity of plate heat exchanger.
