Description
Product description:
SHZQ (S) R intelligent heat exchanger unit is a heat exchanger, a
circulating water pump, water pump, water tank, control cabinet and
pipe valve, the heat exchanging equipment instrument in one.
Control equipment is based on the modern control theory, are
designed and developed by the artificial intelligence, theProgram
control. Practice has proved that the system can, in the case of
unattended, realize the system according to different conditions,
different objective conditions and the user\'s schedule, control of
various scientific and reasonable execution mechanism, so that the
energy optimal control and utilization.
Intelligent heat exchanger unit is the latest technology products
in the international field of heating, realized the automatic
temperature control, automatic constant pressure water supply,
power to protect us from the start, automatic operation
function.
The basic configuration of high efficiency heat turbulent double
cut tube heat exchanger or heat exchanger;
Domestic or imported high-quality brand circulating pump and
vertical water pump;
The sensor and the controller of the SIEMENS brand;
Inverter Sanken brand, Japan\'s Mitsubishi programmable
controller;
User configuration if you have special requirements, the company
can be designed using.
Control the control mode of the heat exchanger unit with three
levels to meet the needs of different users.
Local control
A net is equipped with electric control valve, a network flow
control to control the temperature of two times;
Circulating pump is configured to manually start and stop, and the
electric control valve electric chain function; water pump control
by the expansion tank pressure switch signals to achieve automatic
replenishment.
Full automatic control
A net is equipped with electric control valve, a network flow
control to control the temperature of two times;
With the outdoor temperature compensation function; circulating
pump adopts frequency conversion control, using two net supply and
return water pressure as feedback signal, variable flow control on
the two network; water pump adopts frequency conversion water
supply; controller according to the program to automatically
complete the unit commitment and restoration after the restart;
water pump with a water shortage protection function; the unit
fully automatic operation, only artificial periodic inspection.
Intelligent control
The controller has the function of remote communication, can put
one or two net supply and return water temperature, pressure, flow,
and the water pump, electric control valve, water tank level signal
state, the state of the data is transmitted to the control center,
and be able to control command and control center for remote
communications, the heat exchanger unit to achieve the intelligent
management.
The working principle of the heat medium test (a net
adjustment):
A network adjustment take quantity adjustment, by adjusting the
installation in the electric control valve opening an online, to
regulate a network traffic, a network flow control.
â—‡ hot side (regulation two side):
The two network quality regulation: two circulating pump system
with constant flow pump control, maintain two times the net flow
rate unchanged, through the installation of the electric control
valve to change a flow regulating network to indirectly control the
water temperature of two nets a online, realize the two network
quality regulation.
The two network adjustment: two circulating pump system with
variable frequency control, by changing the supply frequency and
changing the motor speed to change the flow rate of the two
network, the realization of two variable flow network control.
The heat exchanger unit process of a heat source (steam or hot
water) by adjusting the electric valve, and the heat exchange in
the heat exchanger through two water circulating pump pressure,
sent to the user; the condensed water heat exchanger (steam pipe
steam trap) into the water supply tank, by reinforcing the pump set
press to return two times
