Description

Technical Field

[0001] This utility model relates to the field of solar water heating system technology, and in particular to a solar thermal solid storage heating system. Background Technology

[0002] In existing electric energy storage integrated heating systems, electrical energy is converted into heat energy and stored in heat storage materials. The heat exchange system then converts the heat into heat media such as hot air, hot water, and steam according to specific conditions, providing it to customers. However, relying solely on the conversion of electrical energy into heat energy results in high energy consumption and fails to achieve optimal performance.

[0003] Therefore, there is an urgent need for a solar thermal solid-state thermal storage heating system that can meet user needs while reducing energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a photothermal solid-state thermal storage heating system, which solves the problem of high energy consumption caused by the existing technology that only converts electrical energy into heat energy. The various technical effects of the preferred technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The photothermal solid-state thermal storage heating system provided by this utility model includes:

[0007] A PV / T solar collector, wherein the PV / T solar collector is placed on the ground;

[0008] A solid thermal storage boiler, wherein the solid thermal storage boiler is installed on the ground;

[0009] The heat exchanger assembly, wherein the solid thermal storage boiler is connected between the PV / T collector and the solid thermal storage boiler, and is also connected to the user end.

[0010] Preferably, the heat exchanger assembly includes:

[0011] A heat exchange water tank, wherein the heat exchange water tank is installed on the ground;

[0012] The conveying equipment is connected between the PV / T collector and the heat exchange water tank, and between the heat exchange water tank and the solid thermal storage boiler.

[0013] Preferably, the heat exchange water tank comprises:

[0014] A water exchange tank, which is installed on the ground;

[0015] The heat exchangers consist of three sets installed in the exchange water tank. The first set of heat exchangers is connected to the solid thermal storage boiler via the conveying equipment. The second set of heat exchangers is connected to the PV / T collector via the conveying equipment. The third set of heat exchangers is connected to the user terminal.

[0016] Preferably, the conveying device includes:

[0017] The first water supply unit, the first group of heat exchangers is connected to the solid thermal storage boiler through the first water supply unit;

[0018] The second water supply unit connects the second group of heat exchangers to the PV / T collector.

[0019] Preferably, the first water delivery unit includes:

[0020] A boiler inlet pipe is fixedly connected between the top of the first group of heat exchangers and the solid thermal storage boiler, and a first water pump is fixedly connected to the boiler inlet pipe.

[0021] The boiler outlet pipe is fixedly connected between the bottom of the first set of heat exchangers and the solid thermal storage boiler.

[0022] Preferably, the second water delivery unit includes:

[0023] A collector inlet pipe is fixedly connected between the top of the PV / T collector and the second set of heat exchangers, and a second water pump is fixedly connected to the collector inlet pipe.

[0024] The collector outlet pipe is fixedly connected between the bottom of the PV / T collector and the second set of heat exchangers.

[0029] In the technical solution provided by this utility model, the main function of the PV / T collector is to absorb the heat from sunlight and transport it to the heat exchange box assembly, which then provides heat to the user end. The main function of the solid thermal storage boiler is to use electrical energy to heat the solid thermal storage medium to a high temperature of several hundred degrees Celsius, thereby storing heat. When heat needs to be released, an automatic control device starts a fan, causing air to flow through the thermal storage body, exchanging the heat in the thermal storage body into high-temperature air. The high-temperature air heats water, exchanging heat with the water in the heat exchange box assembly, and then transferring the heat to the user end. During the day, the user end mainly receives heat from the PV / T collector. When the heat cannot meet the user's needs, the solid thermal storage boiler can be used to provide heat. At night, the user end mainly receives heat from the solid thermal storage boiler. The heat exchange box assembly automatically controls the heat transfer from the PV / T collector or the solid thermal storage boiler according to day or night. Among them, the solid thermal storage boiler mainly uses inexpensive electricity to heat the solid thermal storage medium to a high temperature of several hundred degrees Celsius during off-peak electricity hours at night, thereby storing heat. Overall, this application can effectively combine solar thermal energy and electrical energy, reduce the energy consumption of the electric energy storage heating system, and ensure heat demand while saving electrical energy.
