Description

Self temperature regulating phase-change energy storage plate
Technical field
The utility model belongs to building material field, relates to a kind of have energy storage, constant temperature function, and the building or the decorative boards of temperature action in the conditioning chamber specifically disclose a kind of self temperature regulating phase-change energy storage plate automatically.
Background technology
The environmental protection society of low-carbon type is the main flow of our times development.At building field, select energy-saving material for use with heat insulation effect, for keeping the constant of temperature in the building, promote energy-saving and emission-reduction, the protection environment has important function.But traditional heat insulating material, its heat capacity is lower, can only can not transform energy by the mode energy storage of sensible heat, therefore, is a kind of power save mode of passive type.How on the basis that ensures heat insulating effect, relying on the performance of architecture-self to adjust interior temperature automatically, reduce heating and air conditioning energy consumption, is the effective way that further improves energy-saving effect.
The phase-change accumulation energy constructional materials is made of phase change material (PCMs) and building charge material matrix, has excellent energy storage and releasability; Compare the common building heat insulating material, have higher heat capacity and thermal inertia.When phase change material microenvironment temperature of living in was lower than transformation temperature, phase change material was condensed into solid-state by liquid state, formed heat release; When phase change material microenvironment temperature of living in was higher than transformation temperature, phase change material formed heat absorption by the solid-state liquid state that is molten into.By storing of this energy, reach the maintenance room temperature, the purpose of energy-saving and emission-reduction.
At present, the method that phase change energy storage technology is applied to building energy saving field has two kinds, a kind of is that phase change material is combined with heat insulating material, utilize suction, the exothermic character of phase change material, intercept flowing of hot-fluid, play the effect of additional " thermal resistance ", increase the thermal inertia of heat insulating material simultaneously, and realize incubation and thermal insulation function jointly with heat insulating material; Another kind is to have made full use of the phase change material sensitiveness of variation of ambient temperature to external world, when using it for indoor environment, the variation of indoor environment temperature will trigger phase change material and undergo phase transition, thereby absorb heat to the environment heat release or from environment, play the temperature damping action, reach the purpose of automatic adjusting interior temperature.Before a kind of method since the restriction of the position of using and environment for use, make the reversible process of phase change material be restricted, thereby influenced its actual energy-saving effect; Then a kind of method, owing to directly apply to the interior space, by choosing of transformation temperature, can in long use, keep the reversibility of phase transition process, by this regulating action, can slow down the fluctuation of interior temperature, prolong the retention time of indoor comfort temperature, thereby reduce air-conditioning or heating system number of run, play automatic adjusting interior temperature, the purpose that cuts down the consumption of energy.Therefore, this kind method has more application prospect in building energy saving field.
The phase-change accumulation energy material is used as the automatic temperature-control material, removes and should solve present ubiquitous leakage problems, also must solve the key issues such as utilization rate problem, durability and applicability of the heat of transformation simultaneously:

2, the utilization rate problem of the heat of transformation.At present the phase change material that uses in building energy saving field is generally organic phase change material, and self coefficient of thermal conductivity is lower, makes that phase-change material is inhaled, rate of heat release is slower, and the utilization rate of the heat of transformation reduces greatly; Particularly adopt the influence of the energy-storage composite material that canned method obtains particularly evident to some; In addition, the wall material in some encapsulating materials such as the phase-change microcapsule is generally high-molecular organic material, and coefficient of thermal conductivity is lower, can form additional thermal resistance, is unfavorable for conducting heat, and greatly reduces the utilization rate of the heat of transformation equally.Often adopts at present the powder that adds high thermal conductivity in phase-change material, for example Al powder, C powder etc. improve the thermal conductivity of system, yet this method exist the powder because of adding that sedimentation easily takes place, thereby influence shortcomings such as thermal conductivity and increase cost.
3, the durability of phase-change accumulation energy constructional materials and applicability problem.
At present, the phase-change accumulation energy constructional materials that uses methods such as microcapsules technology, packaging technique, sol-gel technique or porous mass adsorption technology to obtain, phase-change energy-storage mortar for example, in long-term use, encapsulating material also can lose original function because of reasons such as degraded, aging or breakages, therefore exist phase change material to pass through encapsulating material, to the risk of external migration; The energy-storage composite material that utilizes canned method to obtain more in addition, very poor with the compatibility of common building materials, the mounting process complexity.
