In order to further specify a kind of condensing type constant temperature gas water heater architectural feature of the utility model, its operation principle is described as follows.
Operation principle as depicted in figs. 1 and 2.
Consult Fig. 2 when pressing the on ﹠ off switch (not shown), during setting demand temperature, computer plate 13 is received desired signal, the igniting of starting ignition program, normal combustion, the setting value that hot water temperature's sensor 1 detects actual temperature value and user compares analysis, computer plate 13 is according to the setting of program, reaching requirement is normal combustion, do not reach requirement and then regulate the rotating speed that the combustion gas ratio is transferred electric current and frequency conversion fan 4, thereby guarantee that combustion gas and air reach certain ratio best combustion operating mode, are stabilized in design temperature rapidly and normal combustion.
By shown in Figure 1, cold water passes through water flow sensor 11 from inlet pipeline 9, computerized version 13 starts frequency conversion fan 4 work, gas ratio valve 3 is adjusted gas flow according to program, the blower fan coupling, send into by gas distributor 14 after air and the combustion gas mixing and enter sets of burners 6, produce high-temperature flue gas by sets of burners 6 burnings, through warm flue gas during high-temperature flue-gas are reduced to behind the main switch 8, after in condenser 16, carrying out a heat exchange, in warm flue-gas temperature be reduced to and discharge (shown in the arrow of Fig. 1 upper right side) behind the low-temperature flue gas, cold water absorbs in the coil pipe 17 of condenser and becomes stream of warm water behind the heat and go into main heat exchanger 8, carry out secondary heat exchange in main heat exchanger 8, warm water flows out through becoming high-temperature water behind the main heat exchanger 8, and warm flue gas entered condenser 16 and carries out a heat exchange during high-temperature flue-gas was reduced to.Warm water was sent into main heat exchanger 8 front portions and is carried out secondary heat exchange during the heat that cold water absorbs a heat exchange became, and condensed water occurs simultaneously.
In the process of carrying out a heat exchange, because the decline of flue-gas temperature, on heat exchange tube wall and inner surface, produce condensed water, condensed water flow to condensed water processor 10 along the outlet of condensate draining pipe 12, blow-off pipe (not shown) by tube connector joint 19 after handling enters sewer pipe, because condensed water is to have corrosive acidic liquid, can corrode not carrying out etch-proof metal material, thereby influence the operate as normal and the life-span of condenser, so the part that condenser contacts with condensed water all adopts corrosion resistant metal and nonmetallic materials to be made.
