Anti-freezing electric tracing heating system for solar pipeline

Abstract

The invention discloses an anti-freezing electric tracing heating system for a solar pipeline. The anti-freezing electric tracing heating system for the solar pipeline comprises an electric tracing heating band core which is wound on a solar water supply pipeline, wherein the electric tracing heating band core comprises a lead which is embedded in an electric tracing heating layer, and the electric tracing heating layer is made of PTC material and is located between a cover layer and an inner layer; a temperature sensor is packaged in an insulating layer of the water supply pipeline of a water heater and is connected with the lead; the temperature sensor sends temperature signals to a controller through wires; the lead is connected with a rechargeable battery through the controller; the rechargeable battery is connected with a solar panel; the controller transmits the electric energy of the rechargeable battery to the lead through wires. The anti-freezing electric tracing heating system for the solar pipeline enables the electric tracing heating band to generate heat by means of the power generation of the solar panel, and accordingly the pipeline freezing of the solar water heater is avoided, and the freezing and the fracture of the solar water supply pipeline are avoided effectively.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to an electric heat tracing system for antifreezing of solar pipelines. Background technique [0002] At present, solar energy is related to the daily life of millions of households. But, in winter in the northern region, due to the low temperature, the pipeline is easy to freeze and crack, or the pipeline is blocked, such as water freezing in the water pipe and blocking the solar water supply pipeline. In the past solar pipeline engineering design, other insulation methods have been used to prevent the influence of pipelines due to low temperature, such as insulation materials, electric heaters, steam or hot water heat tracing, etc. However, when the temperature is lower than minus 5°C, the thermal insulation effect of the thermal insulation material is not good, and the phenomenon of freezing and blockage will still occur; when steam is heated to prevent freezing...
