The other end of siphunculus one connects back to wash case, and the plate type water heater connects two one end of tee tube, and described two one end of tee tube connects
Hot water outlet pipe is met, the water outlet of the hot water outlet pipe connects temperature sensor four, and two other end of tee tube connects medicine
Wash pump.
Further, the cold water inlet pipe is equipped with flowmeter one.
Further, flowmeter two is equipped between the tee tube one and plate type water heater.
Further, the flowmeter one and flowmeter two are electromagnetic flowmeter, and it is resistance to that lining material contains neoprene latex
The corrosion resistant material of soda acid.
Further, existing PLC, electronic component, frequency converter and touch screen are installed on the plate type water heater.
The invention has the benefit that
Plate heat exchanger adds electromagnetic flowmeter in intake-outlet, and the Cooling and Heat Source at heat exchanger both ends has display, passes through
The real-time change of flow, is fixed target with cold water end or one flow of hot water end, and the flow of the driving variable frequency pump control other end is big
It is small to realize different flow heat exchange purposes.The exclusive automatic system of design all can may be used according to temperature according to the temperature difference according to flow
To drive the uninterrupted of the frequency shift Cooling and Heat Source of frequency converter, solves the heat exchange efficiency of different flow.Pass through flowmeter pair
Pid control mode than progress realizes 1 to 1 heat exchange, solves the loss of the heat source applied by bathing field.It applies in bath sewage
The mode of recuperation of heat substantially increases energy-saving and environment-friendly application, and plate heat exchanger realizes automatic anti-cleaning, saves artificial cleaning
Operation, reduce in application process heat exchange efficiency caused by the fortuitous events such as blocking and be lost, ensured plate heat exchanger itself
The application efficiency of heat exchange function.
