Embodiment Construction

[0038] A passive zero-energy antifreeze technology and method for equipment based on PCM, see figure 1 , 2 As shown, it includes equipment shell, embedded bracket, PCM layer, inner protective layer, heat insulation layer, outer protective layer, and fireproof paint.

[0039] The PCM mentioned in the present invention, that is, phase change material (phase change material), refers to a class of materials that can absorb or release a large amount of energy (ie phase change enthalpy) when a substance undergoes a phase change. Phase change materials use latent heat to store and release heat. They have the characteristics of high heat storage density, compact structure of heat storage devices, basically unchanged temperature during the phase change process, and easy management. They have great potential for engineering applications.

[0040] The device housing 1 is located at the innermost side; the PCM layer 2 is accommodated in the cavity structure between the device housing 2 a...

Abstract

The invention discloses an equipment passive zero energy consumption freeze-proofing device based on PCM. The equipment passive zero energy consumption freeze-proofing device based on PCM comprises anequipment shell, an embedded support, a PCM layer, an inner protection layer, a heat insulation layer, an outer protection layer and fireproof paint. The equipment shell (1) is located on the innermost side; a liquid phase-change material of the PCM layer (2) is contained in a cavity structure between the equipment shell (1) and the inner protection layer (4); the embedded support (3) is locatedbetween the equipment shell (1) and the inner protection layer (4), and a cavity structure is formed; the heat insulation layer (5) is attached to the outer side of the protection layer (4), and the inner protection layer (4) provides supporting for the heat insulation layer (5); the outer protection layer (6) is fixed to the outer side of the heat insulation layer (5); the fireproof paint (7) coats the outer side of the outer protection layer (6); and the PCM layer (2) is filled with a phase-change material which is liquid at the room temperature. The equipment passive zero energy consumptionfreeze-proofing device based on PCM achieves the technical purpose that freeze-proofing protection can be carried out on equipment under the premise of no power facility or energy consumption; and meanwhile achieves the technical purposes that the equipment structure is simple, implementation is easy, operation and maintenance are convenient, and the requirements for energy conservation and environment protection are met.

Description

technical field [0001] The invention relates to an antifreeze protection technology for equipment, in particular to a zero energy consumption antifreeze technology. Background technique [0002] For a long time, in the northern region, the antifreeze technology of equipment has been the concern of all parties. At present, the commonly used antifreeze technical measures are heat tracing and medium flow. Heat tracing is a technology that supplements heat to the outer wall of the equipment on the basis of heat preservation, so that the equipment can maintain a certain temperature, thereby avoiding the freezing of the working medium in the equipment. Common forms of heat tracing include electric heat tracing, steam tracing, and hot water tracing. Medium constant flow is a technology that adopts the principle of "flowing water does not rot" for antifreeze. Its core is to keep the working medium in the equipment flowing continuously. When the temperature of the working medium ha...
