Description

Technical Field

[0001] The present invention belongs to the technical field of heating equipment, and in particular relates to a single-unit indoor heating system and method. Background Art

[0002] Among the current heating methods, the north mainly uses centralized heating and wall-mounted boiler heating, while in the vast southern and central regions, there is little centralized heating. Some wealthy families use wall-mounted boilers for heating, while most families use heating furnaces or air conditioners for heating. Among them, wall-mounted boiler heating is favored by many people because it currently mostly uses natural gas to provide energy, the overall heating cost is low, and the comfort level is high. However, since the wall-mounted boiler uses a multi-circuit water circuit, it must ensure both domestic water and heating needs in the family. Therefore, the domestic water pipeline for indoor heating is complex and long, and the implementation cost is high. In addition, in home decoration, if you plan to use a wall-mounted boiler heating solution, it means that you need a relatively large decoration budget. Therefore, although ordinary families have such an idea for heating, they are forced to give up.

[0003] At present, due to the diversity of housing types, users of small apartments and some families only want to improve their heating needs in a single room or a few rooms under the current economic conditions, in order to care for the heating conditions of the two special groups of people, the old and the young, in the family, or in industries such as greenhouse planting, a heating system with only a single loop and water supply circulation is needed, which does not require a complex system such as a wall-mounted boiler. In the comparison between natural gas heating and air-conditioning heating, the cost of natural gas heating is relatively low. Therefore, the use of natural gas heating for this part of the market demand, the use of water circulation and then temperature adjustment through the heat sink can meet people's expectations, and the price is moderate, and it will not damage the existing decoration pattern too much. Summary of the invention

[0004] In order to overcome the above technical problems, the present invention provides a single-unit indoor heating system and method, aiming to provide a single-loop water circulation heating solution with flexible layout and reasonable price.

[0005] The present invention adopts the following technical solutions: A single-body indoor heating system includes a radiator, the upstream of the radiator is connected to a gas-fired water heater through a hot water pipeline, the downstream of the radiator is connected to a water tank through a pipeline, the water tank is connected to a submersible pump, the submersible pump is connected to the water heater through a cold water pipeline, the cold water pipeline is provided with a pressure gauge, a flow meter, a flow valve and a pressure regulating valve, the pressure regulating valve, the flow valve and the pressure gauge are connected in parallel, an overflow pipeline is connected between the downstream of the branch pipeline where the pressure regulating valve is located and the water tank, the overflow pipeline is provided with an overflow valve, the water heater is connected to a water heater control detection circuit, the water heater control detection circuit is connected to a control panel, the control panel is also connected to a temperature regulator, the temperature regulator is connected to a frequency converter, and the frequency converter is connected to the submersible pump.

[0006] Preferably, a flame sensor and a gas sensor are arranged inside the water heater, a flow meter 2 is arranged on the water inlet pipeline of the water heater, and a gas regulating valve and a gas flow meter are arranged on the air inlet pipeline.

[0007] Preferably, a water temperature sensor is provided in the hot water pipeline.

Place the equipment according to actual needs, including the location of the heat sink and the selection of installation locations for other equipment; S2. Set the water heater temperature through the control panel, start the water heater through the water heater control detection circuit, ignite the air intake, start the submersible pump through the temperature regulator-inverter to drive the water circulation, and the hot water flows into the heat sink through the hot water pipe. The water that loses heat in the heat sink flows into the water storage tank, which plays a buffering role in the system; S3. When the water pressure pumped out by the submersible pump is higher than the preset value, the water is diverted through the regulating valve and then flows back to the water storage tank through the overflow pipe; S4. The signals collected by the pressure gauge, flow meter 1, flow meter 2, flame sensor and gas sensor are transmitted to the control panel, and the water heater and submersible pump are stopped when an abnormal situation occurs.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a gas-fired water heater as a water heating element, uses a frequency converter to drive a submersible pump as the power for circulating water flow, uses a heat sink as a heat exchange medium, and is provided with components such as a pressure regulating valve and a flow regulating valve to control the system.
