The climate mode of constant change makes millions person gets easily the influence of extreme weather. As temperature wave motion becomes more and more general inside limits, the refrigeration of report of traditional bad news and heat systematic need has innovation sex, more energy-saving replacement scheme one kind more, reduce thereby already the burden of the electrified wire netting of get into trouble. The researcher of A&M university created Dekesasi new-style 3D can be printed change material (PCM) composite material, can use simpler and the workmanship that has cost effectiveness adjusts the environmental temperature of building interior. These composite material can be added in housing materials, if paint, 3D is printed,reside adornment as the home, seam in order to not have blend in different indoor environment. Use the method that can expand to will change material is compositive the ability in housing materials, offerred an opportunity to produce more passive temperature, adjust in new structure and existing structure offerred with Chemstry Department. Heating, ventilated with air conditioning (HVAC) system is the commonly used thermoregulation method in the residence and business organization. Use the conservatory material that calls refrigeration agent to produce cool and dry air. These abidance of HVAC system the problem caused pair of research that replace material and technique, these material and technology need fewer energy to move, and can adjust as proportional as HVAC system temperature.
One of material that arouse wide interest in thermoregulation respect are to change material. These compound can change its physics position according to environmental temperature. Accordingly, should change when material stored heat is measured, they are a liquid from solid change when absorbing quantity of heat, releasing the vice versa when quantity of heat. Accordingly, differ with the HVAC system that relies on exterior power source to heat and cool only, these material are passive component, do not need outside electric power to adjust temperature. The traditional method of production PCM housing materials needs to be all round every PCM grain form a separate case, resemble Cheng Shui's cup, add the PCM of these new package in housing materials next. However, searching as compatible as PCM and its crust housing materials is a challenge all the time. In addition, this kind of traditional method still decreased but the amount that mix into enters the PCM grain in housing materials. To overcome these challenges, the research in the past makes clear, should use change with liquid colophony compound when olefin, colophony can serve as crust already, also can serve as housing materials. Lock of grain of PCM of this kind of method general is surely inside respective pocket, make they can undertake surely change and run heat energy and won't leak. Research group changes photosensitive liquid colophony and photograph first olefin pink photograph is united in wedlock, innovation goes a kind of new 3D to be able to print ink composite material, improved the manufacturing process of the housing materials that contains PCM, removed a few measure that include to be enclosed inside. Colophony / PCM mixture softness, mushy and have extend a gender, suit 3D to print very much, but do not apply to building construction. Accordingly, through using photosensitive resin, they use ultraviolet ray its solidify with solidify but the mash that 3D prints, make its apply to actual application. The photograph that they discover built-in colophony is medium changes the effect that candle does not suffer ultraviolet ray, 70% what hold the construction that print. Compare with the photograph of most usable material that uses in industry at present, this is a higher percentage. They print model of small-sized building appearance through 3D, measure the temperature when putting the house oven, will check its to change the thermoregulation of composite material. The analysis makes clear, the model appearance that makes with traditional material is compared, the temperature of this model and the exterior temperature photograph that heat to heat up a loop with refrigeration are compared differ 40% . Future, researcher divides the experiment the different photograph besides olefin to change material, so that these composite material are OK,move inside wider temperature range, be in given more heat energy run inside cycle. Measurable to building easy maintaining while material is reducing specific power consumption latent capacity feels excited, can rise a variety of PCM couple that have different and fused temperature, allocate them accurately each area of the individual object that print, in order to be in whole effect is produced inside 4 season and limits.
