Closed type plane phase change hot accumulating tank heating system

Abstract

The invention discloses a closed type plane phase change hot accumulating tank heating system. The system comprises a hot accumulating water tank (1), a clamping plate (2), a flow-guide slot (3), a phase change hot accumulating plate (4), an insulating layer (5), a water tank heat exchanging tube (6), a water injecting tube (7), a hot water supplying tube (8), a heating supplying source (10), a drain tube (11) and a hot water heat exchanger (12), wherein valves are installed on tubes and are used for adjusting the flow, and the hot water supplying tube is connected to the hot accumulating tank in a closing or opening mode. When the heating supplying source heats the hot accumulating water tank through the water tank heat exchanging tube, the surplus heat can be stored in a phase change hot accumulating material. When the heating supplying source stops running or the water of the hot accumulating water tank fails to reach the heating temperature through the heating, the phase change hot accumulating plate can release the heat, and the heating hot water maintains at the heating temperature. The phase change hot accumulating material has large hot accumulating amount and stable temperature, the defect of unstable hearting of the heating supplying source is solved, and the system can reduce the volume of the hot accumulating water tank greatly.

Description

technical field [0001] The invention relates to a phase change heat storage heat supply technology, in particular to a heat supply system of a closed flat plate phase change heat storage box. Background technique [0002] In the heating system, some heat sources such as solar energy have intermittent heat supply or stop heating for some time. Phase change heat storage materials can solve the problem of heating heat supply due to their large heat storage and stable temperature storage characteristics. The shortcoming of unstable quantity can prolong the heating time and maintain a stable heating temperature. The current phase change heat storage devices mostly use the shell-and-tube type or encapsulate the phase change materials in capsules. These technologies have complex structures, and the amount of heat storage materials is fixed. They are only suitable for heat storage with fixed heat storage. When the heat supply is not enough to make When phase change occurs in all ph...

The current phase change heat storage devices mostly use the shell-and-tube type or encapsulate the phase change materials in capsules. These technologies have complex structures, and the amount of heat storage materials is fixed. They are only suitable for heat storage with fixed heat storage. When the heat supply is not enough to make When all phase change materials undergo phase change, the heating temperature cannot meet the requirements

Patent CN102338484A discloses a phase change heat storage solar water heater without a heat storage tank. This invention is a solar water heater using phase change materials as the heat storage medium, which solves the problems of high cost and low thermal conductivity of the existing phase change heat storage solar water heaters.

Although this invention also uses phase change materials for heat storage, the phase change materials are directly installed in the vacuum heat collecting tubes, which is essentially different from the present invention; patent CN101915464A discloses a phase change heat storage solar water heater, which solves the problem of The thermal conductivity of the phase change material of the existing phase change heat storage solar water heater is poor, and the heat energy transformed by the solar energy cannot be transferred to the phase change material well. However, the heat storage tank of this system has a complex structure and a fixed form. The present invention achieves the same effect The system structure is simplified under the premise of the system, and it can be disassembled flexibly. The phase change hot plate can be added or subtracted at will with the change of the heat supply, or the phase change hot plate of the corresponding phase change material can be selected according to the difference of the heat supply temperature. module
