At present, the plate heat exchanger unit has realized the intelligent and
remote control technology, and the main heat exchanger is the plate heat
exchanger. By adjusting the temperature and pressure of the heat exchanger, the
water temperature entering the heating area is suitable for normal use. At the
same time, it plays the purpose of protecting supporting equipment and pipes.
Next, let's take a look at the characteristics and advantages of plate heat
exchangers.

Characteristics of plate heat exchanger units.

The plate heat exchanger unit is composed of plate heat exchanger,
intelligent temperature control device, intelligent electric control device,
circulation pump, make-up pump, pressure-stabilized expansion water tank,
condensing water tank, filter, valve, instrument, sensor, piping base, etc.

Plate heat exchanger unit has the advantages of high heat exchange
efficiency, energy saving, intelligence and automation, and can be widely used
in factories, government organs, schools, residential areas and other civil
buildings. Shopping malls, hotels, restaurants, resorts and other commercial
buildings for heating, air conditioning, bath water, domestic water, swimming
pool water in winter, can also be used for the preparation of industrial
production process water, as well as various places that need heat exchange.

The heat exchange medium of plate heat exchanger unit.

1. Water-water heat transfer.

2. Steam-water heat transfer.

Advantages of plate heat exchanger units.

1. Pump automatic conversion: the use of programmable PLC can make the pump
automatic inspection, fault protection, automatic switching, and mutual standby
functions.

2. Power-off protection: the heat source is automatically cut off after a
sudden power outage to protect the heat exchanger from damage.

3, the multi-function touch screen, the operation is more convenient: uses
the man-machine picture touch screen, each parameter is more convenient to
display and operate.

4. Custom temperature setting: the unit can automatically adjust the heat
medium flow according to the heating area and set temperature to save energy
costs.

5. Automatic pressure relief and double protection: when the secondary water
supply pressure is higher than the set value of water supply, the leakage
solenoid valve opens automatically and is equipped with safety valve at the same
time to realize double insurance.

6. Water shortage and pressure loss protection: if the pressure is lower than
the set pressure, the circulating pump will stop running automatically and start
the make-up pump to replenish water, knowing that the pressure is normal.

7, unit one-button start: unit one-button start, can automatically detect
data, automatic control, automatically start make-up pump, circulation pump and
heat source switch and so on.

8, water tank low water level protection: lack of water supply pump
automatically stop pump, protect pump, prevent water pump from burning out
motor.

9. Outdoor temperature compensation: automatically adjust the water supply
temperature of the system according to the outdoor temperature change to save
energy consumption.

10. automatic frequency conversion constant pressure control of make-up pump:
according to the backwater pressure of the system, the frequency conversion
control system has the advantages of constant pressure, good performance and
stable operation.

11. control of water supply temperature is more accurate: Siemens electric
temperature control valve is used to control effluent temperature more
accurately, save energy and reduce consumption. Power outage automatically
closes the entrance of heat medium to prevent accidents.

12. Automatic frequency conversion control of circulation pump: according to
the increase or decrease of user's heating area, automatic frequency conversion
can adjust the frequency, speed and power consumption of circulation pump.

The technical innovation of the plate heat exchanger unit makes up for the
unreliability of the heat pump unit. Through the pressure and temperature
regulation of the plate heat exchanger, the temperature and pressure after
entering the pipe are very suitable for district heating, such as factory, air
conditioning, school, residential area and so on. There are plate heat
exchangers in which to adjust and exchange heat to avoid a series of unstable
accidents caused by high temperature and high pressure.
