Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Generally, a wall-mounted boiler includes a main heat exchanger for heating water, a water inlet pipe and a water outlet pipe are connected to both sides of the main heat exchanger, and an external heating pipe is connected to the water outlet pipe through a heating water supply pipe and to the water inlet pipe through a heating water return pipe. The main heat exchanger, the water inlet pipe, the water outlet pipe, the heating water supply pipe, the heating pipeline and the heating water return pipe jointly form a heating circulating pipeline.
Still be connected with the heat transfer water pipe between inlet tube and the outlet pipe, be provided with the hot water heat exchanger on this heat transfer water pipe, this heat transfer water pipe is connected with outlet pipe, heating delivery pipe through the three-way valve, and through the switching of three-way valve, control switches on heating delivery pipe or heat transfer water pipe. The domestic water pipeline flows through the hot water heat exchanger, and then hot water supply is realized. Wherein, the main heat exchanger, the water inlet pipe, the water outlet pipe and the heat exchange water pipe jointly form a hot water circulation waterway.
Therefore, the main heat exchanger, the water inlet pipe and the water outlet pipe form an overlapped pipeline section of the heating circulating pipeline and the hot water circulating waterway. The water inlet pipe is provided with a circulating water pump which can drive water in the heating circulating pipeline and the hot water circulating waterway to flow. In addition, a water pressure sensor is arranged on the water inlet pipe, so that the water pressure sensor is used for detecting the water pressure in the overlapped pipeline section.
As shown in fig. 1, the water replenishing method of the wall-hanging stove in the embodiment includes the following steps.
S1, judging whether automatic water replenishing is carried out or not, and if so, carrying out S2. The judgment basis of whether the automatic water replenishing work is carried out is to judge whether the replenishing action is started, namely to judge whether the water source is started to feed water into the heating loop. When water is fed, the water pressure in the heating loop is changed.
In this embodiment, whether the water replenishing operation is required or not may be determined by the following method. The water pressure P in the overlapped pipe sections in the hot water circulation waterway and the heating circulation waterway is obtained. Specifically, when the time of the non-working stable state of the wall-mounted boiler reaches a set stable time threshold, the water pressure P in the overlapped pipe sections in the hot water circulation waterway and the heating circulation waterway is collected in real time. The settling time threshold in this embodiment may be set to 4s. The non-working stable state of the wall-mounted furnace can simultaneously meet the following conditions, namely, the state of the circulating water pump is not changed, the state of the three-way valve is not changed, the heating/non-heating state is not changed, the initialization work of the water pressure sensor is completed, and the wall-mounted furnace is in one state of shutdown or failure.
The baseline water pressure is updated at set intervals, is a water pressure value before the water replenishing action is not started, and can be obtained by carrying out average calculation on a water pressure sampling value. When the water replenishing action is not started, the water pressure fluctuation at the position of the water pressure sensor is small and is stabilized in a range with a small water pressure value. If the water pressure fluctuation changes suddenly under the condition that the water pressure value is small, the water replenishing action is judged to be started, and at the moment, automatic water replenishing work is needed.
Specifically, in this embodiment, P is compared with the current baseline water pressure P0, and if P is greater than or equal to P0+ a and P0 is less than the set water pressure, the set water pressure is a highest water pressure threshold value of the wall-hanging stove in the non-working stable state, where P0=0.2bar in this embodiment. And after the duration that P is more than or equal to P0+ a reaches a set duration T0, judging that water replenishing work is needed, wherein a is more than 0 and a is a set pressure difference threshold. The value ranges of T0 and a are respectively as follows: t0 is more than or equal to 1.5s and less than or equal to 5s; a is more than or equal to 0.4bar and less than or equal to 0.6bar. In this example, T0=2s, a =0.5bar.
And S2, alternately filling water into the hot water circulation waterway and the heating circulation waterway so as to enable pipelines of the hot water circulation waterway and the heating circulation waterway to be filled with water. In the embodiment, the three-way valve is controlled to be communicated with the hot water circulation waterway first, and the hot water circulation waterway can be filled with water in a short time. And then the three-way valve is controlled to switch the channel to be communicated with a heating circulating water channel which needs a relatively long time to be filled with water. Therefore, the pipelines of the hot water circulating waterway and the heating circulating waterway are filled with water.
And S3, because bubbles are contained in the water in the hot water circulation water channel and the water in the heating circulation water channel, the water in the hot water circulation water channel and the water in the heating circulation water channel stop circulating flow, namely the circulating water pump is controlled to stop working, at the moment, the water in the hot water circulation water channel and the water in the heating circulation water channel are in a standing state, the bubbles in the water rise and are concentrated together, and further the air exhaust work in the following steps is facilitated.
And S4, alternately performing the exhaust work of water in the hot water circulation waterway and the heating circulation waterway.
The exhaust working method of the water in the hot water circulation waterway comprises the following steps: and controlling the circulating water pump to work so as to drive water in the hot water circulating waterway to circularly flow, and finishing the removal of bubbles in the water flow process. Because the length of the hot water circulating waterway is relatively short, the elimination of air bubbles can be effectively finished within a limited time.
The exhaust working method of the water in the heating circulation waterway comprises the following steps: controlling and driving water in the heating circulation waterway to circularly flow, and finishing the removal of bubbles in water flow in the water flow process;
and then controlling the water in the heating circulation water channel to stand for a set time, and then controlling the circulation water pump to work to drive the water in the heating circulation water channel to circularly flow, so that the air bubbles in the water flow are removed in the water flowing process. Since the heating pipe path in the heating circulation water path is long, it is difficult to completely remove bubbles in water by performing one-time standing and flowing exhaust, and therefore, it is necessary to perform standing again and then flowing exhaust again. Of course, the number of the alternating circulation times of the standing and the flowing of the water in the heating circulation water path in the exhaust process can be specifically set according to the requirement, so that the effect of effective exhaust is achieved.
In this embodiment, the water circulation flow in the heating circulation water path may be controlled to be driven to perform the exhaust operation in the heating circulation water path, and then the water circulation flow in the hot water circulation water path may be controlled to be driven to perform the exhaust operation in the hot water circulation water path. Usually, the hot water circulation waterway can realize the elimination of bubbles, and the heating pipeline is too long, so that all gas cannot be effectively eliminated when the heating circulation waterway performs the exhaust operation, and after the water in the standing heating circulation waterway lasts for a period of time, the water in the heating circulation waterway is controlled and driven to circularly flow so as to further perform the exhaust operation in the heating circulation waterway.
Of course, the alternative sequence of the water exhaust operation of the hot water circulation waterway and the heating circulation waterway can be specifically set according to the requirement.
And S5, circularly carrying out S2 to S4 until the water pressure in the hot water circulating water path and the water pressure in the heating circulating water path reach the set water pressure range, and further completing water supplementing work.
In the water supplementing process, if the wall-mounted furnace fails or the wall-mounted furnace supplies the domestic hot water, the current water supplementing work is stopped, so that the normal use and maintenance of the domestic hot water of the wall-mounted furnace can not be influenced.
Specifically, the procedure of the water replenishing operation of the wall-hanging stove in the present embodiment can be described by table 1 below.
TABLE 1
The above-mentioned times t1, t3, t7 and t9 are all times for switching the circulation water path, that is, times for switching the three-way valve, and are usually short and the time periods of t1, t3, t7 and t9 are substantially equal.
t5 and t11 are the static rising time of the bubbles in each circulation water channel, and the time is relatively long but shorter than the time of water filling and circulation flowing exhaust of the heating circulation pipeline and the hot water circulation water channel.
t2 is the water filling time of the hot water circulation waterway, and the required time is relatively short because the hot water circulation waterway has a short path. And t8 is the time for discharging bubbles in the hot water circulation water path, and the time is relatively long, and the time t8 is generally larger than the time t2, t5 and t 11.
t4 is the water filling time of the heating circulation pipeline, the required time is relatively long due to the long distribution path of the heating pipes in the hot water circulation waterway, the t4 is generally greater than t5 and t11, and the time can be greater than or less than t8 according to the length of the heating pipes.
t6, t10, and t12 are times for discharging bubbles from the heating circulation pipe, and t6, t10, and t12 are longer than t8 because the path length of the heating circulation pipe is longer than that of the hot water circulation pipe.
According to the water replenishing method for the wall-mounted furnace, after water replenishing is started, water replenishing can be automatically completed without depending on manpower, and the water replenishing can be started by an installer when the wall-mounted furnace is installed for the first time or by a remote control water replenishing valve when the wall-mounted furnace needs water replenishing. According to the water replenishing method of the wall-mounted furnace, the discharge of bubbles in the circulating water path is realized through an effective strategy, the water replenishing speed is accelerated, the water replenishing period is shortened, the number of times of water replenishing by service personnel to the home is reduced, even the operation to the home is not needed, and the service cost is low. And can guarantee final good moisturizing effect, the water pressure after the moisturizing reaches and sets for the water pressure promptly, guarantees the water pressure condition in the use, and the moisturizing is realized simply.
