The following describes the working process of the wall-mounted boiler provided by the embodiment of the utility model in detail with reference to fig. 2.
The wall-mounted boiler working modes of the embodiment of the utility model comprise a heating mode, a domestic hot water supply mode and a domestic hot water supply mode.
1. When the heating mode is started, the domestic water outlet pipe 62 is first closed, the first control valve 511 of the heating water outlet pipe 51 is opened, and the second control valve 521 on the heat source water return pipe 52 is closed.
The ignition device 7 is then activated, the gas enters the gas pipe 72, the ignition needle 71 is ignited, high temperature flue gas is generated, and heat is provided to the first heat exchanger 1.
Cold water in the cold water pipe 31 enters the first heat exchanger 1 to be heated, and heated hot water flows into the hot water pipe 32. The real-time temperature of the water heated by the hot water is detected by the temperature limiter 321, and if the real-time temperature exceeds the set limit temperature, a command is sent to stop the machine set when the machine set is flameout, so that the safety is ensured.
The hot water in the hot water pipe 32 enters the second heat exchanger 2, and the hot water flows into the heat source outlet pipe 5. Since the first control valve 511 is opened and the second control valve 521 is closed, the hot water flows only through the heating water outlet pipe 51, and does not flow through the heat source water return pipe 521. The hot water flowing into the heating outlet pipe 51 enters the house heating pipeline to realize heating of the house. Finally, the cold water discharged from the house heating pipe flows into the heating return pipe 53, and flows into the cold water pipe 1 again through the water pump 4.
Here, the first temperature sensor 512 detects the water temperature of the heating water outlet pipe 51 in real time, and the water pressure sensor 531 detects the water pressure on the heating water return pipe 53 in real time.
2. When the domestic hot water supply mode is started, the domestic water outlet pipe 62 is first opened, the first control valve 511 of the heating water outlet pipe 51 is closed, and the second control valve 521 on the heat source water return pipe 52 is opened.
The ignition device 7 is then activated, the gas enters the gas pipe 72, the ignition needle 71 is ignited, high temperature flue gas is generated, and heat is provided to the first heat exchanger 1.
Cold water in the cold water pipe 31 enters the first heat exchanger 1 to be heated, and heated hot water flows into the hot water pipe 32. The real-time temperature of the water heated by the hot water is detected by the temperature limiter 321, and if the real-time temperature exceeds the set limit temperature, a command is sent to stop the machine set when the machine set is flameout, so that the safety is ensured.
The hot water in the hot water pipe 32 enters the second heat exchanger 2, and the hot water flows into the heat source outlet pipe 5. Since the first control valve 511 is closed and the second control valve 521 is opened, the hot water flows only through the heat source return pipe 52, and does not flow through the heating outlet pipe 51. The hot water flowing into the heat source return pipe 52 flows into the cold water pipe 1 through the water pump 4, and then enters the first heat exchanger 1 to be heated, and then becomes hot water. That is, in this mode, a heat source capable of exchanging heat with the cold water in the second heat exchanger 2 is continuously generated through the above-described circulation passage. Also, since the first control valve 511 of the heating outlet pipe 51 is closed, the hot water of the heat source outlet pipe 5 does not pass through the house heating pipe, so that the heat generated from the wall-hanging boiler is entirely used for heating the domestic cold water.
Tap water then enters the second heat exchanger 2 through the life water inlet pipe 61, and after heat exchange with the hot water entering through the hot water pipe 2, flows into the life water outlet pipe 62 to supply life hot water.
Here, the second temperature sensor 621 detects the temperature of the service outlet pipe 62 in real time.
3. When the mode of simultaneously heating and supplying domestic hot water is started, the domestic water outlet pipe 62 is first opened, the first control valve 511 of the heating water outlet pipe 51 is opened, and the second control valve 521 of the heat source water return pipe 52 is opened.
The ignition device 7 is then activated, the gas enters the gas pipe 72, the ignition needle 71 is ignited, high temperature flue gas is generated, and heat is provided to the first heat exchanger 1.
Cold water in the cold water pipe 31 enters the first heat exchanger 1 to be heated, and heated hot water flows into the hot water pipe 32. The real-time temperature of the water heated by the hot water is detected by the temperature limiter 321, and if the real-time temperature exceeds the set limit temperature, a command is sent to stop the machine set when the machine set is flameout, so that the safety is ensured.
The hot water in the hot water pipe 32 enters the second heat exchanger 2, and the hot water flows into the heat source outlet pipe 5. Since the first control valve 511 is opened and the second control valve 521 is opened, the hot water is circulated both on the heating outlet pipe 51 and on the heat source return pipe 521. That is, the hot water of the heat source outlet pipe 5 is split into two pipe flows.
The hot water flowing into the heating outlet pipe 51 enters the house heating pipeline to realize heating of the house. Finally, the cold water discharged from the house heating pipe flows into the heating return pipe 53, and flows into the cold water pipe 1 again through the water pump 4.
The hot water flowing into the heat source return pipe 52 flows into the cold water pipe 1 through the water pump 4, and then enters the first heat exchanger 1 to be heated, and then becomes hot water. That is, a heat source capable of exchanging heat with the cold water in the second heat exchanger 2 is continuously generated through the above-described circulation path.
Tap water then enters the second heat exchanger 2 through the life water inlet pipe 61, and after heat exchange with the hot water entering through the hot water pipe 2, flows into the life water outlet pipe 62 to supply life hot water.
The heating is realized through the working process, and meanwhile, domestic hot water can be provided.
Here, the first temperature sensor 512 detects the water temperature of the heating water outlet pipe 51 in real time, the second temperature sensor 621 detects the temperature of the living water outlet pipe 62 in real time, and the water pressure sensor 531 detects the water pressure on the heating water return pipe 53 in real time.
In the operation process of the three modes, the heat dissipation device 9 provides enough air quantity to play roles in smoke discharging and heat dissipation.
In summary, according to the wall-mounted boiler provided by the embodiment of the utility model, the new waterway channel and the heat exchanger are designed, and the flow direction of water is controlled by the control valve, so that three different modes of heat supply are provided, and the requirements of heating and domestic hot water are met. And the structure is simple, the weight is reduced, and the cost is reduced.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
