Water pump 501, main heat exchanger 120, three-way valve 210, heating outlet pipe 102 form heating water route.Tap water
The composition life of water inlet pipe 504, double-tube heat exchanger 110, plate type heat exchanger 130, domestic hot-water's outlet pipe 303
Hot water water route.Domestic hot-water's temperature sensor 304 it is provided with on domestic hot-water's outlet pipe 303.When there being life heat
During water demand, three-way valve 210 is switched to domestic hot-water's state, now, water pump 501, heating return pipe 101,
Main heat exchanger 120, heating outlet pipe 102, three-way valve 210, plate type heat exchanger 130, double-tube heat exchanger 110
Circulation waterway in composition.
Referring to Fig. 4, double-tube heat exchanger 110 is by sleeve pipe 410, heat exchanger tube 420 and some pipe joints etc.
Composition, some pipe joints go out with preheating entrance 111, preheating outlet 112, heat release entrance 113 and heat release respectively
Mouth 114 connects.As it is shown in figure 5, the import of heat exchanger tube i.e. heat release entrance 113 connecting plate type heat exchanger 130
Heat exchange outlet 132, the outlet of heat exchanger tube i.e. heat release outlet 114 connection heating return pipes 101.It is appreciated that
Heat exchanger tube inner channel is a part for interior circulation waterway.The import of sleeve pipe i.e. preheats entrance 111 and connects from the beginning
Water water inlet pipe 504, the outlet of sleeve pipe i.e. preheats outlet 112 connecting plate type heat exchangers 130.It is appreciated that and changes
The part that passage is domestic hot-water water route constituted outside heat pipe and inside sleeve pipe.In the present embodiment, sleeve pipe
Outside be provided with rapid hot water temperature sensor 302.
In one embodiment, this wall-hung boiler is provided with rapid hot water function, when user does not opens rapid hot water function,
Wall-hung boiler receives domestic hot-water's demand, and three-way valve 210 is switched to domestic hot-water's state, water pump 501, blower fan
503 run, and gas valve 507 is opened, i.e. burner 506 ignition of system ignition, main heat exchanger
Water in 120 is heated to form high-temperature-hot-water, enters board-like changing after flowing through heating outlet pipe 102 and three-way valve 210
The heat release of hot device 130, then carry out secondary heat release, then through water pump 501 and heating by double-tube heat exchanger 110
Return pipe 101 flows back to main heat exchanger 120 and absorbs heat, and so circulates.
Low temperature tap water then flows to double-tube heat exchanger 110 by tap water water inlet pipe 504 and preheats, then
Entrance plate type heat exchanger 130 carries out secondary heat absorption and becomes high-temperature-hot-water, then flows through domestic hot-water's outlet pipe 303
Go out.Tap water water temperature after preheating has a certain degree of rising, with the temperature of domestic hot-water's target leaving water temperature
Subtractive is little, now enters plate type heat exchanger 130 and absorbs heat, and the time reaching target leaving water temperature can shorten, from
And domestic hot-water is quickly provided.
In one embodiment, when user opens rapid hot water function, in the standby state, if Rapid Thermal water temperature
Degree sensor 302 detects when water temperature is less than design temperature and the temperature difference reaches certain value, i.e. TRapid hot water≦(TSet
-△T1), three-way valve 210 is switched to domestic hot-water's state, and system boot ignition, in interior circulation waterway
Water starts the cycle over, and in plate type heat exchanger 130 and double-tube heat exchanger 110, the water temperature of circulation waterway raises, due to
Now the water in domestic hot-water water route is immobilising, under conductive force, and plate type heat exchanger 130 and sleeve pipe
The water temperature in heat exchanger 110 domestic hot-water water route also increases.Work as TRapid hot water≧(TSet-△T2) time, △ T2<
△T1, system-down.
When there being domestic hot-water's demand, in plate type heat exchanger 130 and double-tube heat exchanger 110 domestic hot-water water route
Preheating water flow out at first, so in wall-hung boiler heating set-up procedure, just can provide the hot water of uniform temperature.
Meanwhile, in heating up process, low temperature tap water first flows to double-tube heat exchanger 110 and preheats, then
Entrance plate type heat exchanger 130 carries out secondary heat absorption and becomes high-temperature-hot-water, then flows through domestic hot-water's outlet pipe 303
Go out, it is possible to domestic hot-water is provided faster.When preheating under holding state, user does not has domestic hot-water to need
Ask, for reducing the waste of energy, it is not necessary to the temperature of preheating water is heated to design temperature.Generally,
Preheating water can be heated to 30-35 DEG C, the time going out hot water can shorten to about 5 seconds, make user without etc.
Treat, reduce the discharge of cold water.
As shown in Figure 6 and Figure 7, plate type heat exchanger 130 need to be arranged on due to double-tube heat exchanger 110 and master changes
The backwater section of the interior circulation waterway between hot device 120, to utilize high-temperature tempering that tap water is preheated, institute
Can also be located between water pump 501 and main heat exchanger 120 with double-tube heat exchanger 110, heat exchanger tube import connects
Water pump 501, outlet connects main heat exchanger 120.Sleeve pipe import connects tap water water inlet pipe 504, and outlet connects
Plate type heat exchanger 130.The tap water of double-tube heat exchanger 110 can be following current heat exchange with interior recirculated water, it is also possible to
Countercurrent flow is used to improve heat transfer effect.
Concrete, as shown in Figure 6, following current heat exchange refer to tap water after tap water water inlet pipe 504 enters by
The preheating entrance 111 of sleeve pipe 410 enters, from preheating outlet 112 inflow plate type heat exchanger 500 after heat absorption.As
Shown in Fig. 7, countercurrent flow refer to tap water from tap water water inlet pipe 504 enter after by the preheating of sleeve pipe 410
Outlet 112 inflow, flows into plate type heat exchanger 500 from preheating entrance 111 after heat absorption.It is appreciated that following current is changed
The endothermic process of the tap water of heat and countercurrent flow is different, and therefore heat transfer effect also differs.
Beneficial effects of the present invention:
1) when opening rapid hot water function, can be in plate type heat exchanger and double-tube heat exchanger under holding state
Water preheats, and when receiving domestic hot-water's demand, just can provide uniform temperature in heating set-up procedure
Hot water, user without waiting for, and decrease the discharge of cold water.
2) when tap water is carried out heat temperature raising, utilize double pipe heat exchanger that tap water is preheated, energy
Enough improve the inflow temperature of plate type heat exchanger, shorten temperature rising-time.
