Description

Solar household heating and hot water device

technical field

The utility model relates to a heating and hot water device using solar energy and electric energy complementary, in particular to a household heating and hot water device.

Background technique

Present solar water heater mainly is to supply hot water, utilizes its heating sometimes heat is not enough, needs to supplement with other energy sources, but structure is more complicated, and cost is high, is not suitable for family single-family use.

Contents of the invention

The purpose of the utility model is to provide a solar energy household heating and hot water device, which can ensure temperature by complementary heating of solar energy and electric energy, and is very convenient to use hot water.

The technical scheme of the utility model is as follows:

The device includes a solar heat collector, a controller, a circulation pump, a thermal insulation water tank, an electric heater, and a heat exchange tube; The water pipe of the water tank is then connected to the solar heat collector. The insulated water tank is filled with demineralized water. There is a heat exchange tube in the above water tank. The circulation pump is connected to the heating radiator, and its return pipe is connected to the bottom of the above-mentioned heat preservation water tank; there is an electric heater in the above heat preservation water tank, and the heater is connected to the power supply through the controller.

The above-mentioned controller is a temperature difference controller.

Above-mentioned heating radiator is the radiating pipe of ground heat.

The above-mentioned demineralized water is distilled water.

The utility model has the advantages of: 1. With this device, solar energy and electric energy are complementary. When the water temperature of the water tank is lower than the water temperature of the solar heat collector, the water in the water tank is heated by the solar heat collector. When the temperature of the water tank is not enough, the electricity The heater starts to compensate for heating, hot water and heating can be used on demand, and the control is reliable. 2. Demineralized water is used in the heat preservation water tank, so that the solar collectors, heating radiators and electric heating rods are not scaled, prolonging their service life and reducing maintenance costs. 3. The hot water is the hot water exchanged from the heat-exchanging water tank through the heat exchange tube. The fresh water heated by tap water is used, and solar energy and electric energy complement each other. The water tank maintains the set temperature, and the water consumption is not limited. Just tap water anytime. 4. Distilled water is used in the water tank, which is non-conductive and highly safe.

Description of drawings

Fig. 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Can see that this device comprises solar thermal collector 2, controller (19,5,16), thermal insulation water tank 9, electric heater 7, heat exchange tube 12 by Fig. 1, solar thermal collector 2 is through controller 19, supply The thermal circulation pump 4 and pipeline 1 are connected to the thermal water tank 9 in the room, and its water supply pipe 20 is connected to the bottom of the above-mentioned water tank. In the heat preservation water tank, there is distilled water in the heat preservation water tank. There is a heat exchange tube 12 in the above water tank. 16. The heating circulation pump 14 is grounded to the heating radiator pipe 15, and its return pipe 13 is connected to the bottom of the above-mentioned water tank, and its controller is also a temperature difference controller, and its temperature sensor 17 is placed in the room for heating; there is an electric heater 7 in the above-mentioned water tank , this heater connects power supply through controller 5, and its controller is also temperature difference controller, and its temperature sensor 8 places in the heat preservation water tank; 18 is ground.

When in use, when the temperature of the solar collector is higher than the temperature of the heat preservation water tank, its controller will start the heating circulation pump to provide hot water to the heat preservation water tank, and stop when it reaches the set temperature of the water tank; when the solar heat supply cannot make the heat preservation When the water in the water tank reaches the set temperature, the electric heater starts to heat and supplement heat, and stops heating after reaching the set temperature; Circulation in the heating radiator pipe stops when reaching its set temperature; when the water temperature in the water tank is sufficient, the tap water in the heat exchange pipe in the water tank can be heated, and domestic hot water can be used at any time.
