Self-temperature controlling water-electricity dual-purpose composite pipes

Abstract

The invention discloses a self-controlling-temperature water electric dual-purpose composite pipe, which is fabricated by that a self temperature control heating tape added by a metal wire braid layer is attached to the outer wall of a plastic flexible pipe, then metal shielding radiation membranes are wrapped outside the plastic flexible pipe and the self temperature control heating tape, and a reinforced sheath is extruded on the shielding radiation membranes. The self-controlling-temperature composite pipe can provides two modes of heat supply, which are water heating mode and electric trace heating mode, inner circulation hot-water of the plastic flexible pipe primarily supplies heat, and the self temperature control heating tape is in auxiliary heat supply. The self-controlling-temperature composite pipe can be used as a terminal of geothermal heating, which resolves the problem that when renewable energy green resources, such as solar heat collecting, air source heat pump systems and the like, are used in construction heating in winter, the existing water coils can not meet heating requirements under condition of unstable hot-water temperature or relatively low water temperature, and has the advantages of energy conservation, safety and reliability, low operation costs, environmental friendliness and the like.

Description

technical field [0001] The invention relates to a terminal device for building heating, in particular to a self-controlling temperature-hydraulic dual-purpose composite pipe suitable for geothermal heating. Background technique [0002] With the rapid development of the economy and the gradual improvement of people's living standards, energy shortage and environmental pollution have become prominent problems faced by today's society. Energy saving, safety, and environmental friendliness have become the development direction of building heating products, and the utilization of renewable green energy such as solar heat collection and air source heat pump systems has attracted increasing attention. When the above-mentioned renewable green energy is used for building heating in winter, the heat transfer medium is hot water, and the living environment is heated through pipeline circulation. For solar heat collection, due to different regions, changes in day and night and climate...

AI Technical Summary

Problems solved by technology

The air source heat pump system also has the above defects due to the change of air temperature.

At the same time, the water temperature of the pipeline is unstable with the outside air temperature, the insulation and length of the pipeline, and the dynamic and static transmission state.

The current solution is to use auxiliary heating methods such as constant power electric heating tube built-in storage tank method, frequency induction constant power method, electric and gas water heaters or electric and gas boilers. The disadvantages of these auxiliary heating methods are large investment and high energy consumption. , high operating costs and potential safety hazards, etc., which are contrary to the concept of energy saving and consumption reduction
