Abstract

The utility model relates to a phase change material energy storage floor heating device, having packaged phase change material modules placed inside a heating floor pipe embedding layer. A composite hydrous salt phase change material at the temperature of about 29 DEG C is packaged into an orthogonal trapezoidal table body module by using a plastic material, and is alternately arranged on a heat insulation layer inside the heating floor pipe embedding layer along the coiling direction of embedded pipes in the mode that the materials with phase change are equidistant to the materials without phase change; coil pipes are inlayed among the phase change material modules; periphery and the upper part of the phase change material modules are filled and covered with sand stone concrete. When hot water is injected into the coil pipes, heat energy can be stored in the phase change materials, and the heat is emitted into rooms as needed.

Description

Phase-change material accumulation of energy floor heating device

Affiliated technical field

The utility model relates to a kind of low-temperature water heating accumulation of energy floor heating device that utilizes phase-change material, especially the energy storage materials of phase change module of encapsulation is placed the pipe laying layer medium heat disk pipe accumulation of energy heating floor device on every side of heating floor.

Background technology

The floor heating technology is very fast in China development in recent years, and along with building energy conservation and the renewable energy utilization pay attention to day by day at building and field of heating ventilation air conditioning, utilizing regenerative resource such as solar energy is the trend of the times of floor heating technical development.Total institute is known, solar-heating is warm to exist certain contradiction with demand, because solar energy can only have the solar time to supply with by day, all the other periods can't provide, and, lacking the solar time, the demand of heat supply is big more, and the accumulation of energy of general heating floor concrete pipe laying layer is very limited, and the heat that can't be supplied with daytime stores for using evening.

Summary of the invention

There is the mismatch problem of Supply and Demand on T/A in order to solve solar heating effectively, realize that heating floor stores heat daytime, dusk and night are to the floor heating of room heat release, the utility model provides a kind of phase-changing energy-storing floor heating device, this device is on the heat insulation layer in heating floor pipe laying layer, arrange packaged phase-change material accumulation of energy module by certain mode, coil pipe is embedded between the phase-change material module, coil pipe can store heat in the phase-change material when feeding hot water, in needs to indoor heat release.

The technical scheme that its technical problem that solves the utility model adopts is: arrange the energy storage phase change material module in the pipe laying layer of heating floor.Phase-change material employing phase transition temperature is a kind of compound hydrated salt about 29 ℃, be leakage and the corrosion that prevents material in the phase transition process, be packaged into the module of trapezoid platform with a right ang shape with plastic material, its upper base be the square of length of side 42.5mm, the wide 42.5mm of big long 60mm that goes to the bottom rectangle, highly be 30mm.Because the phase-change material energy storage density is big, need in the pipe laying layer, all not fill, need only along the pipe laying coil direction by have, alternate being arranged on the heat insulation layer of the equally spaced mode of no phase-change material module, coil pipe is embedded between the phase-change material module, phase-change material module periphery and top thereof are filled with sand-stone concrete and are covered, can play and support the effect of weight on the ground, prevent its crushing, help the uniformity of ground surface temperature simultaneously again the phase-change material module.The beneficial effects of the utility model are, when coil pipe in the accumulation of energy floor heating device fed hot water, heat stored in the phase-change material in the pipe laying layer of floor, when temperature descends, phase-change material can discharge the heat that stores, and can be according to demand in the required time section to indoor heat release.Be a kind of economy, environmental protection and the energy-conservation heating floor device of realizing utilizing solar heating.
