Its expression formula is as follows:
γ=（τ2-τ1）/τ1
Wherein, γ is relative time hysteresis rate, τ 1 is that common composite plate is under the heat transfer of extraneous thermal environment, arrived the time (by temperature polling instrument 9 records) of comfort temperature higher limit by the low temperature rising, τ 2 is that the phase-change accumulation energy composite plate is under the heat transfer of extraneous thermal environment, by the time (by temperature polling instrument 9 records) of low temperature rising arrival comfort temperature higher limit.The meaning that this indirect energy saving index is expressed is: extraneous hot-fluid sees through composite plate or phase transformation composite plate and enters in the indoor situation that causes indoor intensification, the relatively common composite plate of phase-change accumulation energy composite plate stops indoor temperature to raise, until exceed the time relative value of indoor comfort temperature.This index can be used for estimating the ability that common composite plate or phase transformation composite plate are kept indoor comfort temperature time length.The γ value is larger, and it is large to show that the phase-change accumulation energy composite plate is kept the multiple of time lengthening of indoor comfort temperature, and energy-saving effect is better.

Test and evaluation example:
In test case, with the utility model device blank foaming plaster plate and the energy-efficient performance that adds the phase transformation foaming plaster plate of 10% phase-change material are compared test.Because its phase transition temperature of phase-change material of adding is 26 ℃, meets the Summer Indoor comfort temperature, the use in winter poor effect, therefore take summer simulation test as example.
Experimental procedure is as follows: test specimen to be measured is fixed on the casing 1, and casing 1 is placed high-low temperature test chamber.It is indoor at temperature controller casing 1(to be set) initial temperature is 22-23 ℃, (because casing 1 outer temperature is higher than the temperature inside the box, the temperature inside the box keeps rising, and therefore only has refrigerator to work independently herein to open refrigerator.Winter simulation similarly only has heat-producing machine work usually), temperature reached and keep this temperature, with it as indoor initial temperature.This temperature is middle and lower reach of Yangtze River Area during Summer cold in winter and hot in summer medial temperature in evening, considers and takes venting practice evening in summer, so that indoor temperature is near outdoor temperature, so adopt this temperature as initial temperature certain rationality to be arranged.
(outdoor) set temperature is 34 ℃ on high-low temperature test chamber, and this temperature also calculates according to summer typical case daily temperature, therefore has ubiquity and rationality.Close the cabinet door, after everything is ready, start high-low temperature test chamber, this moment, box outside temperature will rise to 34 ℃ very soon.The start-up temperature logging carries out Real-time Collection to temperature in the casing, and uses the PC save data.Temperature range is 26-28 ℃ in the prefabricated casing on temperature controller, so that when temperature in the casing surpasses 28 ℃, temperature controller starts refrigerator casing is lowered the temperature, until drop to 26 ℃, when temperature raises once again, then again start refrigerator, so repeatedly, make the interior temperature of casing maintain 26-28 ℃ of this human body comfort temperature.Be connected in the electric energy meter 11 between refrigerator 4 and the temperature controller 10, its power consumption is carried out record, whole experimentation continues 12h.
After utilizing this method that common foaming plaster plate and phase transformation foaming plaster plate are tested respectively, the time-temperature curve that multipath temperature patrol inspection instrument 9 gathers as shown in Figure 2.
Can be found out that by this figure it is 3580s that common foaming plaster plate reaches 28 ℃ of used times from 24 ℃, the plasterboard of interpolation phase-change material is 8560s consuming time then, and according to the indirect energy saving evaluation index, its relative time hysteresis rate is:
γ=(8560-3580)/3580×100%=139.1%
This result shows: after the phase-change material of interpolation 10%, the time of keeping indoor comfort temperature has prolonged 1.39 times than ordinary gypsum board in the foaming plaster plate.
In 12h, keeping comfort temperature institute power consumption by the common foaming plaster plate that records on the electric energy meter is 0.132KWH, and phase transformation foaming plaster plate loss electric weight is 0.0891KWH.According to direct evaluation index, its relative energy-saving efficiency is:
η=(0.132-0.09405)/0.132×100%=28.7%
This result show the phase-change energy-storage gypsum plate that added phase-change material than ordinary gypsum board in 12h, keep during the indoor comfort temperature institute's consuming electric power low 28.7%.
Interpretation of result is learnt through experimental test:
Carry out summer during simulation test, do not add the common composite plate (control piece) of phase-change material because its thermal capacitance is little, " house " interior temperature variation is very fast, and it is shorter that temperature rises to the time (by the temperature polling instrument record) of comfort temperature value, therefore it is very fast that " house " starts refrigerating plant, start also more frequently, so power consumption (by electric energy meter record) is more; Add the energy storage composite plate (test specimen) of phase-change material, because the phase-change material that the energy storage composite plate is added has relatively high thermal capacitance, its phase transition temperature is near the human body comfort temperature, when ambient temperature is higher than phase transition temperature, the solid-liquid phase change heat absorption occurs in it, causes " house " interior temperature to raise and relatively lags behind, and (time is longer relatively late therefore to start refrigerating plant, by the temperature polling instrument record), total power consumption less (by the electric energy meter record).Phase-change accumulation energy composite plate simulation test in winter with summer simulation test similar.By the simulation comparison test, can be used for estimating phase-change accumulation energy composite plate thermal property and energy-saving effect, instruct preparation, design and the installation of phase-change accumulation energy composite plate.
What deserves to be explained is; above-described embodiment only is used for explanation the utility model; wherein the concrete structure of each parts, connected mode etc. all can change to some extent; every equivalents and improvement of carrying out on the basis of technical solutions of the utility model all should do not got rid of outside protection domain of the present utility model.
