1) In the mode of separately supplying heating water, as shown in fig. 2, when the wall-mounted boiler is operated in winter, if the user does not have the requirement of domestic hot water, the controller controls the opening of the auxiliary port of the flow distributor 5 communicated with the heat storage heat exchanger 6 to be 0, the opening of the port of the flow distributor 5 communicated with the first outlet 18 is maximum, the flow distributor 5 controls all hot water heated by the burner 3 to be supplied to the heating pipeline 11, the controller controls the first valve 13 and the second valve 14 to be in the closed state, water in the wall-mounted boiler circulates according to the arrow indication direction in fig. 2, and all hot water heated by the burner 3 flows to the heating pipeline 11 (such as a floor heater or a radiating fin) arranged indoors to perform heat radiation, so that the mode of separately supplying heating water is realized.
2) In the mode of independently supplying domestic water, as shown in fig. 3, when the wall-mounted boiler is operated in summer, because the user has no heating requirement, the controller controls the opening of the port of the flow distributor 5 communicated with the first outlet 18 to be 0, the opening of the auxiliary port of the flow distributor 5 communicated with the heat storage heat exchanger 6 is maximum, the flow distributor 5 controls all hot water heated by the burner 3 to be supplied to the heat storage heat exchanger 6, the controller controls the first valve 13 to be closed, the second valve 14 to be opened, water in the wall-mounted boiler circulates according to the arrow indication direction in fig. 3, all hot water heated by the burner 3 flows to the heat storage heat exchanger 6, heat storage media in the heat storage heat exchanger 6 are heated through coil heat transfer in the heat storage heat exchanger 6, further, the domestic water is heated, the mode of independently supplying the domestic water is realized, the set water temperature of the user can be kept constant, the user can use the wall-mounted boiler immediately after the user is started, and the problem that the wall-mounted boiler is frequently started due to small water requirements of brushing teeth, washing hands and the like of the user is avoided.
3) And simultaneously, the mode of supplying heating water and domestic water is that when the wall-mounted boiler is operated in winter, a user has the requirements of domestic hot water and heating hot water, an auxiliary port communicated with the heat storage heat exchanger 6 by the flow distributor 5 and a port communicated with the first outlet 18 by the flow distributor 5 are provided with openings, the flow distributor 5 controls the hot water heated by the burner 3 to be respectively supplied to the heating pipeline 11 and the domestic water pipeline which are operated in parallel, as shown in fig. 4, the controller controls the first valve 13 to be closed, the second valve 14 to be opened, and the water in the wall-mounted boiler circulates according to the arrow indication direction in fig. 4, so that the requirements of the user on the heating water and the domestic water are met.
Specifically, in order to improve the user's comfort, the controller controls the flow distributor 5 to preferentially satisfy the demand of domestic water while maximally satisfying the demand of heating water. When the user uses the bathroom hot water for a long time, the water temperature in the heat storage heat exchanger 6 is reduced, the set temperature value of the user is different from the actual temperature of the fourth temperature detection device 7, the controller controls to increase the flow of the water pump 15 and the opening of the proportional valve 16 of the burner 3, increase the temperature of the second temperature detection device 4, and control the flow distributor 5 to increase the flow of hot water to the heat storage heat exchanger 6, when the actual temperature detected by the fourth temperature detection device 7 is lower than the set temperature of the user, the flow of hot water to the heat storage heat exchanger 6 by the flow distributor 5 is continuously increased until the temperature detected by the fourth temperature detection device 7 is equal to the set temperature of the user, then, whether the actual temperature detected by the third temperature detection device 10 is lower than the set heating temperature of the user is judged, and when the actual temperature detected by the third temperature detection device 10 is lower than the set heating temperature of the user, the controller controls the flow distributor 5 to increase the flow of hot water to the heating pipeline 11 until the actual temperature detected by the third temperature detection device 10 is equal to the set heating temperature of the user.
When the wall-hanging stove supplies heating water and domestic water simultaneously, the two flow paths can also operate in a series connection mode, as shown in fig. 5, the controller controls the opening of the port, which is communicated with the first outlet 18, of the flow distributor 5 to be 0, the opening of the auxiliary port, which is communicated with the heat storage heat exchanger 6, of the flow distributor 5 to be maximum, the flow distributor 5 controls all hot water heated by the burner 3 to be supplied to the heat storage heat exchanger 6, the controller controls the first valve 13 to be opened, the second valve 14 to be closed, water in the wall-hanging stove circulates according to the arrow indication direction in fig. 5, and the heat remaining after the hot water heated by the burner 3 exchanges heat with the heat storage medium in the heat storage heat exchanger 6 is reused in the heating pipeline 11. The wall-mounted boiler adopts the operation condition that the water temperature of the auxiliary heating pipeline 20 after heat exchange of the heat storage heat exchanger 6 is still larger than the preset heating temperature, and when the difference value between the two is larger than 5 ℃, the residual heat after heat exchange of the heat storage heat exchanger 6 is ensured to be effectively used for heating, and the operation mode is that the bathroom hot water is mainly and the heating is auxiliary, so that the heat is fully utilized. When the domestic water meets the preset temperature or the detected temperature of the first temperature detecting device 12 is less than or equal to the preset heating temperature and the difference value between the two is less than 5 ℃, the wall hanging stove is automatically switched to the parallel operation mode shown in fig. 4.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
