Unit fluorine system works principle
Compressor 1 work, the refrigerant gas of discharge HTHP is after cross valve 2 dead electricity; Refrigerant gas gets into first condenser 3 and second condenser, 4 water inner and that need to heat carry out heat exchange, and cold-producing medium liquefaction gets into throttling arrangement 5 after the heat exchange, entering evaporimeter 6 after throttling arrangement 5 step-downs; After evaporimeter 6 evaporations, become low-pressure gas; The low-pressure gas cross valve 2 of flowing through is compressed machine 1 return-air mouth and sucks behind gas-liquid separator 7, constituted the circulation on fluorine road.
Unit water system operation principle
The directly-heated operation:
When the user needs the Fast Heating water; Controller 9 will be controlled the second electromagnetism two-port valve 10 and open; The first electromagnetism two-port valve 8 cuts out, and this moment, running water entered into second condenser 4 and heat exchange is carried out in first condenser, 3 inside, heat exchange after heat current direction hot water outlet pipe through the running water water inlet pipe; Simultaneous temperature sensor 11 detects the hot water temperature; Reached the target temperature that controller 9 is set when detecting the hot water temperature, temperature sensor 11 is given controller 9 with signal feedback, and controller 9 continues to keep this temperature hot water with the control system.In this process; Running water is the disposable target temperature that reaches controller 9 settings after first condenser 3 and the 4 inner heat exchange of second condenser directly; Effectively reduced the discharge of internal system, increased the temperature difference of internal system, low discharge, the requirement of the temperature difference greatly when having satisfied system's directly-heated operation; Make the heating capacity of system improve, heat outlet capacity and also improved thereupon.
Circular flow:
When the user does not need the Fast Heating water; Controller 9 will be controlled the first electromagnetism two-port valve 8 and open, and the second electromagnetism two-port valve 10 cuts out, and this moment, the moisture two-way got into internal system from the beginning; One the tunnel is that running water enters into first condenser, 3 inside through circulating water inlet and carries out heat exchange; Heat exchange after heat current direction hot water outlet pipe, simultaneous temperature sensor 11 detects the hot water temperature, does not reach the target temperature that controller 9 is set when detecting the hot water temperature; Temperature sensor 11 is given controller 9 with signal feedback, and controller 9 continues the circular flow heat hot water with the control system.After only having reached the target temperature of controller 9 settings to temperature sensor 11 detection hot water temperatures, controller 9 just control systems stops circular flow; Another road is that running water enters into second condenser, 4 inside through circulating water inlet and carries out heat exchange; Hot water flows to the hot water outlet pipe through tube connector after the heat exchange; Simultaneous temperature sensor 11 detects the hot water temperature; Do not reach the target temperature that controller 9 is set when detecting the hot water temperature, temperature sensor 11 is given controller 9 with signal feedback, and controller 9 continues the circular flow heat hot water with the control system.After only having reached the target temperature of controller 9 settings to temperature sensor 11 detection hot water temperatures, just control system of controller stops circular flow.In this process, system heats water simultaneously through two-way, has effectively increased the discharge of internal system; Reduced the temperature difference of internal system; The requirement of big flow, the little temperature difference makes the heating capacity of system improve when having satisfied the systemic circulation operation, heats outlet capacity and has also improved thereupon.
