Description
Technical field
The utility model relates to a kind of hot-water heating system, especially a kind of more water cell hot-water heating systems belong to water heater skill
Art field.
Background technique
It is well known that many places such as hotel, restaurant, bath center need to be equipped with the water tank of big volume, to meet collection
The middle demand with water.In order to guarantee and operating cost economy stable in supply water temperature, application No. is 201020266310.5,
201420563354.2、201520703674.8、201510580171.0、201610426679.X、201620740017.5、
201710776138.4,201711454949.9 Chinese patent literature successively discloses and large-tonnage water tank " breaks the whole up into parts "
For the technical solution of mutual series-parallel small volume heating water tanks.
Wherein, the technical solution most typical meaning of 201510580171.0 patent disclosures of authorization.The patent disclosure
Hot-water heating system includes interconnected the first, second hot water apparatus and water storage device being made of respectively heat pump and positive displacement,
Water storage device has for supplying the water outlet of user's water and for the water inlet of moisturizing, water storage device includes water tank, out
The mouth of a river and water inlet are set to water tank, and water tank also has a first opening and the second opening, and the first opening of water tank can be with
Second opening of the connection of the second hot water apparatus, water tank can be connected to the water intake end of the first hot water apparatus.
When work, if the hot water heated through the first hot water apparatus meets requirement of the water tank to water temperature, the second hot water dress
It sets and is not turned on, therefore is more economical；When it is necessary to start the heating of the second hot water apparatus, therefore the hot water of itself and the first hot water apparatus
Mixing output, therefore reduce water temperature fluctuation.In addition, the cascade water tank first order setting water outlet, last as water storage device

The cooling water inlet of volume type heating water installations T0 is connected to the hot water outlet of first order heat-storage water tank unit T1, prime storage
The cooling water inlet of hot water box unit is connected to the hot water outlet of rear class heat-storage water tank unit, and equipped with only permission between connecting pipeline
Rear class heat-storage water tank unit hot water outlet flow to the check valve of prime heat-storage water tank unit cooling water inlet；The cold water of afterbody into
Mouth is connected to water water source.
The water outlet of heat-pump water heater T passes through check valve and volume type heating water installations T0 and heat storage water tank at different levels respectively
The short circuit import of T1-Tn is connected, and the short circuit outlet of volume type heating water installations T0 and heat storage water tank T1-Tn at different levels pass through on-off respectively
Valve is simultaneously connected through circulating pump P with the water inlet end of heat-pump water heater T.
When operation, more water cell hot-water heating systems of the present embodiment can have following various working conditions:
1) discharge water merely state --- as shown in Fig. 2, cold water by afterbody heat storage water tank Tn enter after, by it is rear forward by
Grade goes out hot water "top", until other pipelines are closed from volume type heating water installations T0 to water lines supplying hot water；Hot water supplies in this way
Should be very sufficient, and buffer step by step, therefore hot water temperature is sufficiently stable.
2) positioning cycle heats --- as shown in figure 3, being detected when according to the prediction of regimen condition and heat storage water tank water temperature at different levels
Determine a certain heat storage water tank, when for example Tn-2 needs to heat, individually opens the on-off valve and circulating pump P of heat storage water tank Tn-2, heat
The hot water of pump water heating apparatus T output enters the water tank by the short circuit import of heat storage water tank Tn-2, while will be wherein relatively cold
Water forms the circulating-heating of the water tank out to heat-pump water heater T by short circuit outlet is " crowded ", makes a reservation for until water temperature reaches required
Temperature.
3) discharge water while concurrent heating --- as shown in figure 4, being detected when according to the prediction of regimen condition and heat storage water tank water temperature at different levels
Determine a certain heat storage water tank, when for example Tn-2 needs to heat, individually opens the on-off valve and pressure pump of heat storage water tank Tn-2, heat pump
Hot water apparatus T output hot water by heat storage water tank Tn-2 short circuit import enter the water tank, will wherein relatively cold water by short
Exit is " crowded " out to heat-pump water heater T, forms the circulating-heating of the water tank；Cold water is by afterbody heat storage water tank Tn simultaneously
After, hot water "top" is gone out step by step forward by rear, until in this way may be used from volume type heating water installations T0 to water lines supplying hot water
To select suitable intermediate water tank concurrent heating, the stabilization hot water needed for more providing in time according to water demand.

Hot water entered by afterbody heat storage water tank Tn after, hot water "top" is gone out step by step forward by rear, up to being filled by positive displacement hot water
T0 is set to the water circulation that water supply pipe is full of hot water always with water lines supplying hot water, is formed, hereafter no matter when and where uses water,
It can instant-heating.
5) water tank adapter tube heat preservation --- as shown in fig. 6, in the short circuit inlet ductwork and short circuit of afterbody heat storage water tank Tn
Pass through pipeline heat insulation on-off valve F between export pipeline to be shorted, i.e., after avoidable standing for a long time when unlatching circulating-heating, because of water tank
Water temperature in circulation adapter tube reduces the caused impact to water temperature in heat storage water tank, therefore adding for heat storage water tanks at different levels may be implemented
After the completion of heat, pipeline heat insulation on-off valve F and circulating pump P is opened, at the water tank adapter tube for keeping heat storage water tank and heat-pump water heater
In closed circulation Heat preservation state, remain that water temperature therein does not drop.
The present embodiment compared with prior art, due to that only need to control volume type heating water installations during discharging water, controls
Logic simplifying；Especially water tank can be cascaded so that flexible small admonitory talk to subordinates heating is intermediate on demand, therefore can be to avoid unnecessary water
Case disturbance, keeps system water flow and water temperature stability.
