Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a kind of plastic cloth, in particular to a laminated air chamber plastic cloth. [Previous technology] 5 With the advancement of science and technology, crops that were only abundant in specific seasons can now be planted and harvested in all four seasons, mainly due to the large number of covering insulation materials used in agricultural greenhouses, tunnel sheds, and horticultural work. Due to the growing environmental conditions, crops that could not be cultivated in the past can be earlier or delayed in production, thereby increasing yield and improving quality. Currently, the common covering materials on the market can be divided into two categories: glass and plastic. Referring to the first figure, most of the heat-insulating glass plates 1 used to cover the greenhouse frame (not shown) are double-layered, and the space between the glass plates k is filled with air, or it can be a more expensive vacuum. deal with. Since the glass plates 1 themselves have a convection against heat energy, they can achieve a part 15 thermal insulation effect. In addition, there is air with low heat transfer efficiency between the glass plates 1, and even the vacuum treatment can cut off the heat energy to conduct. The method is passed from one side of the glass plates 1 to the other. Other relevant practitioners chose to install air-conditioning equipment in the greenhouse to ensure the stability of the temperature inside the insulation room. However, its less ideal is nothing more than 20. The insulation effect between the air and the glass plate is still not very complete. In addition, the weight of the glass plate is too heavy. It must rely on the frame with a very high structural strength. It is extremely difficult and challenging, and the cost of glass plates is high. If the area of the greenhouse is too large, the overall construction cost will be surprisingly expensive. In addition, if the air-conditioning equipment is used for a long-term operation, the cost will be 200410819. The invention description (2) is undoubtedly a very heavy burden. In view of this, at present, relevant industries have gradually turned to using plastic materials to make covering materials. Common plastic products can be divided into materials such as polyethylene (PE) and polyvinyl chloride (PVC). Their biggest feature is that they are thin and light. Virtuous 5 10 15
好且又防水。但正由於實際使用上多半是採取單層舖設的 方式，常因為單層的塑膠覆蓋材料過於輕薄，而無法有效 阻絕夜間熱能向外逸散的缺失，因而喪失阻絕保溫之功能 ;此外，該種塑膠製覆蓋材料在使用12至18個月後通常 會產生脆化現象，一般業者多半選擇在覆蓋材料產生脆化 現象之前，便先行更換新的塑膠覆蓋材料，在此同時卻造 成了廢棄物數量大增，且每更換一次所耗費的採購與舖設 成本更是不可避免的支出，故目前有相當多的農科專家正 投入相關領域中，希望能夠製造出最具實用性，且符合成 本效益之產品。 【發明内容】 因此’本發明之目的，即在提供可以有效降低熱能耗 損之複層氣室塑料布。 於是，本發明之低熱損複層氣室塑料布包含有：至少 -間隔排列之第-基膜’及複數分別變折設置於任兩相鄰 第一基膜間之第二基膜。其中一第二基膜在相鄰之其中二 第一基膜間界定出複數個第-氣室，該等第一氣室彼此不 相連通且分別填充有-惰性氣體，其中一第二基膜於界定 出第一氣室之其中-第-基膜與其中另一第一基膜間界定 出複數値第二氣室，該等第二氣室彼此不相連通並分別填 6 20 200410819 玖、發明說明（3 ) .:. 充有一溫室效應氣體。位於同一平面上之第一氣室共同界 定出至少一熱阻斷層，而位於同一平面上之第二氣室共同 界定出至少一熱效應層。 當熱能自該低熱損複層氣室塑料布的一側往另一側傳 5 遞過程中，由於該熱阻斷層中之惰性氣體的熱傳導率極低 ，故大部分熱能無法有效透過惰性氣體的傳導而繼續向外 逸散，同時該熱效應層中的溫室效應氣體吸收熱能後會加 以反射，故藉著輕射方式傳遞的熱能亦不易直接通過該熱 效應層，因而達到蓄熱保溫的效果。 10 【實施方式】 本發明之前述以及其他技術内容、特點與優點，在以 下配合參考圖式之數較佳實施例的詳細說明中，將可清楚 的明白。 參閱第二圖，本發明低熱損複層氣室塑料布2的第一 15 較佳實施例是包含：三層上下相間隔之第一基膜21、21， 、21，、二分別彎折設置於任兩相鄰第一基膜間21、21， 、21的第一基膜22、22’，及一位在最外層之其中一第 一基膜21外侧的低輻射膜23。 該等第一、二基膜21、21，、21 ”、22、22,分別為表 20 層不含有氣及溴的多層共擠複合薄膜，該多層共擠複合薄 膜係選自於乙烯酸乙烯共聚體（EVA )、聚偏二氣乙烯 (PVDC)、乙烯-乙烯醇共聚合物（EV〇H)，及氧化矽其 中至少兩者所層疊共擠而成。在本實施例中該多層共擠複 合薄膜是乙烯-醋酸乙烯共聚體、聚偏二氯乙烯及乙烯_乙 7 200410819 砍、發明說明（4 ) 烯醇共聚合物三者層疊共擠而成，其中聚偏二氯乙稀並不 位於最外層。 其中一第二基膜22在相鄰之該等第一基膜21、21， 間界定出複數個第一氣室24，該等第一氣室24彼此不相 5 連通且分別填充有一惰性氣體，在本實施例中該惰性氣體 為氬氣。界定出第一氣室24之其中一第一基膜21，與相鄰 之另一第一基膜21，，間，被其中另一第二基膜22,界定出 φ 複數個第二氣室25，該等第二氣室25彼此不相連通且分 別填充有一溫室效應氣體，在本實施例中該溫室效應氣體 1〇 為臭氧。位於同一平面上之第一氣室24共同界定出一熱 阻斷層26’而位於同一平面上之第二氣室25共同界定出 一熱效應層27，其中該熱阻斷層26較該熱效應層27更 為相對鄰近該低輻射膜23，且在本實施例中該低輻射膜 疋由不米級鈦酸钾晶鬚（K2Ti6〇12 )所製成，當然其他 15具有相同效果的材質也是可以被允許使用的。 φ 配合第三圖，每一第一氣室24與每一第二氣室25之 ^截面皆呈蜂巢狀，且其中任一第一氣室24與位於上方 之二個相鄰第二氣室25形成局部重疊，其中一第二氣室 25與位於下方之相鄰三個第一氣室24形成局部重疊。 * 20 士口 笛一 —圖所示’該低熱損複層氣室塑料布2適用於霜 1 又 ^溫室框架（圖 >未示出）上，該低熱損複層氣室塑料布 、的上方是外界環境3，而下方則是被該低熱損複層氣室 f =布2所環繞隔離出的空間4。白天時陽光自外界環境 “、、射通過該低熱損複層氣室塑料布2(如圖中左側假想線 8 200410819 软、發明說明（3 ) …， 箭頭所示），以加熱該空間4中的所有物體，當然也包括 了空氣，使得該空間4中的溫度升高；而當夜晚時，外界 環境3溫度在缺乏陽光照射的情況下迅速降低。根據熱力 學第二定律，熱的傳遞方向是由溫度較高處往溫度較低處 5 流動’其中，以對流傳遞者佔10-15% ，以傳導傳遞者佔 30-50% ，以輻射傳遞者則是佔有50-60%左右，因此，超 過半數以上的熱能傾向是利用輻射方式由該空間4往外界 環境3傳遞（如圖中右側假想線箭頭所指）。 基於「黑體輻射」原理，也就是任何溫度高於絕對溫 1〇 度者都會以輻射的方式發散能量，因此，該空間4中所蓄 積的熱能與種植在該空間4中的作物所發散出的熱能，也 稱為紅外線，便不斷地自該空間4通過該低熱損複層氣室 塑料布2往外界環境3發散。 然而當該空間4中的熱能向外發散的過程中首先便會 15 遭遇到該低輻射膜23，將該空間4中的溫度預設在〇-60 C之間’根據威恩定律Wien’s Law【波長（//m) =2897/ (nC+273.15 )】加以換算，此段波長約落在87-1〇6#m 之區間，該低輻射膜23恰好對於此區間波長之紅外線有 極為優異的反射效果，可將大部分之熱能反射回該空間4 2〇 中，一部份未被該輻射膜所反射回該空間4之熱能便 進入該熱阻斷層2¾。 當熱能進入該熱阻斷層26會與該惰性氣體接觸，由 於惰性氣體是自然界中熱傳導效率最低的氣體，其中氮的 熱傳導係數約為4.9*HT5cal/cm2/sec*t，是空氣的〇.〇8倍 9 200410819 玖、發明說明（6), ，當然，氪氣也是很好的選擇，其熱傳導係數約為 2.6*l(T5cal/cm2/sec*°C，是空氣的0.04倍，但氪氣受限於 目前尚未平價量產，故仍以氬氣為較佳選擇。如此一來， 違熱阻斷層26中的惰性氣體並不容易作為傳遞熱能的媒 5 介’僅有極少部分的熱能可以繼續往外發散。 縱使微量熱能藉由該惰性氣體順利地往外界散出而進 入該熱效應層27，該熱效應層27中之溫室效應氣體仍可 ^ 吸收熱能並進而輻射回該空間4中；在本實施例中選擇臭 氧作為溫室效應氣體的主要原因在於··臭氧對於紅外區段 10有特別強烈的吸收現象，特別是以9·6 // m為中心的區段 ，故借用臭氧對於輻射熱能的攔截作用，並蓄存此輻射熱 能再加以輻射回該空間4中，達到實際的溫室效應。 另根據文獻的記載，自然界中正六邊形蜂巢型態的空 間，其熱輻射損失較低，故該等第一、二氣室24、25的 15特殊空間設計也能夠減少熱能的減，以至於熱能無法往 φ 外界環境3逸出，配合上本發明將每一氣室24、25的高 度控制在6-9mm以下，而氣體分子在—^限制高度下無 法產生熱對流現象，並維持在穩定的靜風狀態，因此該空 Μ 4中的溫度遂不至於因外界環境3溫度下降 20 降低。 f本實施射’隨著外界溫度逐漸下降，熱能是由該 低熱知複層氣室塑料布2的下方（即該空間4)往上方（即外 界王衣境3)流動，除了依靠該低熱損複層氣室塑料布2本身 、、邑熱月匕對机外’另在熱能輻射的過程中先受到該低輻 200410819 玖、發明說明（7 ) 射膜23的擋止，而將大部分之熱能反射回該空間4中， 極少部份通過該低輻射膜23之熱能則會先後遭遇該等熱 阻斷層26、熱效應層27，該熱阻斷層26中填充之惰性氣 體具有極低的熱傳導效應，使得通過該低輻射膜23之絕 5 大部分熱能並無法藉著傳導方式通過該熱阻斷層26，配 合上該熱效應層27中之溫室效應氣體吸收來自該熱阻斷 層26之熱能並加以輻射回到該熱阻斷層26，最後回到該 空間4中，故最後能夠順利通過該熱效應層而發散到 外界環境3的熱能是微乎其微，以達到最低熱能耗損之目 1〇 的；此外，由於每一第一氣室24與每一第二氣室25皆呈 蜂巢狀也能輔助減少熱輻射損失，且任兩位於不同高度之 氣室24、25不完全重疊，即使該低熱損複層氣室塑料布 2的厚度較薄，也能藉由交錯設置之氣室24、25而提高 整體結構強度。 15 20 另外，在本發明中值得注意的是··該等第一、二基 1 21 、22、22’是由乙烯·醋酸乙烯共聚體、聚 二氣乙烯及乙烯-乙稀醇共聚合物三者共擠而成，因此 阻透性較—般單層塑膠覆蓋製品更優異，當然也可以是 自t乙稀-醋酸乙烯共聚體、聚偏二氣乙稀、乙歸-乙埽; =聚合物，及氧切其中至少兩者共擠製成，其他具有丨 力=也是报好的選擇，且隨著選擇的材料娜 二基膜 21、21，、21，’、22、22’的_ 離電再者，臭氧是一種極為活潑且攜_ 體刀子，很可能對該等第一、二基膜21、2】 11 玖、發明說明（8 ) 古21、22、22’進行溶渗，為確保該低熱損複層氣室塑料 布2的敎性與安純，㈣成料第…二基膜21、 5 I、21”、22、22’的其中-種原料_聚偏二氯乙烯於共擠 =!是位於最外侧的一層，以避免臭氧直接與聚偏 -氣乙烯中的氣原子接觸發生反應，導致該等第―、二基 膜—21、21，、21，，、22、22’溶渗，進而縮短該低熱損複層 氣室塑料布2的使用壽命。Good and waterproof. However, due to the fact that most of the practical use is a single-layer laying method, often because the single-layer plastic covering material is too thin and thin, it cannot effectively prevent the lack of thermal energy from escaping at night, thus losing the function of blocking insulation; in addition, this kind of Plastic covering materials usually have embrittlement after 12 to 18 months of use. Most manufacturers generally choose to replace the plastic covering materials with new ones before the embrittlement occurs. At the same time, the amount of waste is caused. It has increased significantly, and the procurement and laying costs for each replacement are unavoidable. Therefore, a lot of agricultural experts are currently investing in related fields, hoping to produce the most practical and cost-effective product. [Summary of the Invention] Therefore, the object of the present invention is to provide a double-layered air chamber plastic cloth which can effectively reduce thermal energy loss. Therefore, the low-heat-loss multi-layer air cell plastic cloth of the present invention includes: at least -the first base film 'arranged at intervals, and a plurality of second base films which are respectively disposed between two adjacent first base films. One of the second base membranes defines a plurality of -air chambers between two adjacent first base membranes. The first air chambers are not connected to each other and are filled with -inert gas, one of the second base membranes. A plurality of second air chambers are defined between the -the first base membrane defining the first air chamber and the other first base membrane. The second air chambers are not connected to each other and are filled with 6 20 200410819 玖, Description of the invention (3) ..: Filled with a greenhouse gas. The first air chambers on the same plane collectively define at least one thermal blocking layer, and the second air chambers on the same plane collectively define at least one thermal effect layer. During the transfer of thermal energy from one side of the plastic sheet of the low-heat-loss multi-layer gas chamber to the other side, most of the thermal energy cannot effectively penetrate the inert gas because the thermal conductivity of the inert gas in the thermal blocking layer is extremely low. The conduction continues to escape outward, and at the same time, the greenhouse effect gas in the heat effect layer absorbs the heat energy and then reflects it, so the heat energy transmitted by the light emission method is not easy to directly pass through the heat effect layer, thereby achieving the effect of heat storage and insulation. 10 [Embodiments] The foregoing and other technical contents, features, and advantages of the present invention will be clearly understood in the following detailed description of preferred embodiments with reference to the drawings. Referring to the second figure, the first 15 preferred embodiment of the low-heat-loss multi-layer air-chamber plastic cloth 2 of the present invention includes: three first base films 21, 21, 21, and 2 spaced apart from each other. A first base film 22, 22 'between any two adjacent first base films 21, 21, and 21, and a low-emission film 23 outside one of the outermost first base films 21. The first and second base films 21, 21, 21 ", 22, 22 are respectively the multi-layer co-extruded composite films of Table 20 which do not contain gas and bromine. The multi-layer co-extruded composite films are selected from ethylene vinyl acetate. Interpolymer (EVA), polyvinylidene dioxide (PVDC), ethylene-vinyl alcohol copolymer (EVOH), and at least two of silicon oxide are laminated and co-extruded. In this embodiment, the multilayers are co-extruded. The extruded composite film is an ethylene-vinyl acetate copolymer, polyvinylidene chloride, and ethylene_ethylene 7 200410819. Explanation of the invention (4) The enol copolymer is laminated and co-extruded, of which polyvinylidene chloride and ethylene It is not located in the outermost layer. One of the second base films 22 defines a plurality of first air chambers 24 between the adjacent first base films 21 and 21, and the first air chambers 24 are not connected to each other and Each is filled with an inert gas, which in this embodiment is argon. One of the first base films 21 of the first gas chamber 24 and another adjacent first base film 21 are defined. The other second base film 22 defines a plurality of second air chambers 25 of φ, and the second air chambers 25 are not connected to each other and are separated. Do not fill it with a greenhouse gas. In this embodiment, the greenhouse gas 10 is ozone. The first gas chambers 24 on the same plane collectively define a heat blocking layer 26 'and the second gas on the same plane. The chamber 25 collectively defines a thermal effect layer 27, wherein the thermal blocking layer 26 is relatively closer to the low-radiation film 23 than the thermal effect layer 27, and in this embodiment, the low-radiation film is made of a meter-level potassium titanate. Whiskers (K2Ti6〇12) are made, of course, other 15 materials with the same effect can be used. Φ In accordance with the third figure, a cross section of each first air chamber 24 and each second air chamber 25 All are in a honeycomb shape, and any one of the first air cells 24 overlaps with two adjacent second air cells 25 located above, one of the second air cells 25 and three adjacent first air cells located below 24 forms a partial overlap. * 20 Shikou flute one—shown in the figure: The low heat loss multi-layered air cell plastic sheet 2 is suitable for frost 1 and the greenhouse frame (Figure > not shown), the low heat loss multi-layered air cell The upper part of the plastic cloth is the external environment 3, while the lower part is damaged by this low heat Laminar air chamber f = isolated space surrounded by cloth 2. During the day, sunlight from the outside environment ", shot through the low heat loss multi-layer air chamber plastic cloth 2 (as shown on the left imaginary line 8 200410819 soft, invention description ( 3)…, shown by the arrow) to heat all objects in the space 4, including air, of course, so that the temperature in the space 4 rises; and at night, the temperature of the external environment 3 in the absence of sunlight Down quickly. According to the second law of thermodynamics, the direction of heat transfer is from the higher temperature to the lower temperature 5 ', of which 10-15% are convective transmitters, 30-50% are conductive transmitters, and radiative transmitters It accounts for about 50-60%, so more than half of the thermal energy tends to be transmitted from the space 4 to the external environment 3 by means of radiation (as indicated by the imaginary line arrow on the right). Based on the "black body radiation" principle, that is, any temperature that is 10 degrees above the absolute temperature will radiate energy, so the thermal energy stored in the space 4 and the crops grown in the space 4 will emit Thermal energy, also referred to as infrared, is continuously emitted from the space 4 through the low-heat-loss multi-layered air cell plastic sheet 2 to the external environment 3. However, when the thermal energy in the space 4 is radiated outward, the low-emission film 23 will be encountered first, and the temperature in the space 4 will be preset between 0-60 C 'according to Wien's Law [ Wavelength (// m) = 2897 / (nC + 273.15)], the wavelength in this section falls in the range of 87-1〇6 # m, and the low-radiation film 23 has an extremely excellent wavelength for infrared in this range. With the reflection effect, most of the thermal energy can be reflected back into the space 4 20, and a part of the thermal energy that has not been reflected back into the space 4 by the radiation film enters the thermal blocking layer 2¾. When thermal energy enters the heat-blocking layer 26, it will be in contact with the inert gas. Since the inert gas is the gas with the lowest thermal conductivity in nature, the thermal conductivity of nitrogen is about 4.9 * HT5cal / cm2 / sec * t, which is 0. 〇8 times 9 200410819 发明, description of the invention (6), of course, thoron is also a good choice, its thermal conductivity is about 2.6 * l (T5cal / cm2 / sec * ° C, 0.04 times that of air, but 氪Due to the fact that gas has not yet been mass-produced at parity, argon is still the better choice. In this way, the inert gas in the thermal barrier layer 26 is not easy to be used as a medium for transferring thermal energy. The thermal energy can continue to radiate outward. Even if a small amount of thermal energy is smoothly diffused to the outside through the inert gas and enters the thermal effect layer 27, the greenhouse effect gas in the thermal effect layer 27 can still absorb thermal energy and then radiate back into the space 4; The main reason for choosing ozone as a greenhouse gas in this embodiment is that ozone has a particularly strong absorption phenomenon in the infrared section 10, especially the section centered at 9.6 // m, so borrowing ozone for radiant heat can Intercepting effect, and storing this radiant heat energy and radiating it back into the space 4 to achieve the actual greenhouse effect. In addition, according to the records in the literature, the space of regular hexagonal honeycomb type in nature has low heat radiation loss, so it should be Waiting for the special space design of the first and second air chambers 24 and 25 can also reduce the reduction of heat energy, so that the heat energy cannot escape to the φ external environment 3. In cooperation with the present invention, the height of each air chamber 24 and 25 is controlled to 6 Below -9mm, the gas molecules cannot produce thermal convection at the height limit of ^ and maintain a stable calm wind state, so the temperature in the air M 4 will not be reduced by 20 due to the temperature drop of the external environment 3. As the external temperature gradually decreases, the thermal energy flows from the low-temperature-knowledge multi-layered air cell plastic sheet 2 (that is, the space 4) to the upper side (that is, the outer clothing layer 3), except for the low-heat-loss multi-layer The air chamber plastic sheet 2 itself, and the hot-air dagger on the outside of the machine, and in the process of thermal energy radiation, it was first blocked by the low-radiation 200410819 玖, invention description (7), and the majority of the thermal energy was reflected. Back to the space 4 In the process, a small part of the thermal energy passing through the low-emission film 23 will encounter the thermal blocking layer 26 and the thermal effect layer 27 in succession. The inert gas filled in the thermal blocking layer 26 has a very low thermal conduction effect, making it pass through the Most of the low-emissivity film 23 can not pass through the heat-blocking layer 26 by conduction, and the greenhouse effect gas in the heat-effect layer 27 absorbs the heat energy from the heat-blocking layer 26 and radiates it back. The heat-blocking layer 26 finally returns to the space 4, so the heat energy that can be successfully passed through the heat-effect layer to the external environment 3 is minimal to achieve the lowest thermal energy loss of 10; The honeycomb shape of the first air chamber 24 and each of the second air chambers 25 can also help reduce heat radiation loss, and any two air chambers 24 and 25 located at different heights do not completely overlap, even if the low heat loss multi-layer air chamber plastic The thickness of the cloth 2 is thin, and the overall structural strength can also be improved by staggered air chambers 24 and 25. 15 20 In addition, it is worth noting in the present invention that the first and second radicals 1 21, 22, and 22 'are made of ethylene · vinyl acetate copolymer, polyethylene gas, and ethylene-ethylene copolymer. The three are co-extruded, so the permeability is better than the general single-layer plastic covering products. Of course, it can also be from t-vinyl acetate-vinyl acetate copolymer, polyvinylidene diene, ethyrene-acetam; = Polymer, and at least two of them are made by co-extrusion. Others have a force = is also a good choice, and with the choice of materials Na 2 base film 21, 21, 21, ', 22, 22' _Ionization. Furthermore, ozone is a very active and portable knife.

The second embodiment of the low-heat-loss multi-layered air chamber plastic cloth of the present invention is substantially the same as the first one. Its special features are: ^ The low-heat-loss multi-layered air chamber cloth 5 is formed in total. Two thermal effect layers 57, 57 and the thermal blocking layer% of the thermal effect layers 57, 57 '. The low-heat-loss multi-layer gas-to-plastic cloth 5 further includes two reinforced films 58 located on the outer side of the first base film Η. The reinforced films 58 are made of nylon 6. 'Nylon 1212 is also suitable Material selection. In this embodiment, in addition to the air chambers 54 and 55 being stacked one above the other, the design of the reinforced membrane 58 is added, so the structural support strength and tensile tension can be improved, and the original thermal effect is $ 57. In addition, another thermal effect layer 57 is formed, and the thermal blocking layer 56 is located between the thermal effect layers 57 and 57, although the thermal blocking layer% and the thermal effect layer ^ are arranged in a staggered arrangement. However, ㈣ can reduce the proportion of thermal energy emitted outward, and the formation of the thermal effect | 57, has the overall effect of adding reflection to the slight thermal energy from the thermal blocking layer 56. Referring to the fifth figure, the third embodiment of the low heat loss multi-layered air cell plastic sheet 6 of the present invention is formed with three thermal blocking layers 66 and four thermal effect layers 12 200410819 发明, invention description (9), and the second The preferred embodiment is the same in that the thermal blocking layers 66 are located between the thermal effect layers 67 and 67, and two of the thermal effect layers 67 are relatively adjacent to the breach space 4, and the other two thermal effect layers 67 are relative Proximity to the external environment 3. The low-heat-loss multi-layer air-cell plastic sheet 6 further includes a reflective film 69 located outside the low-radiation film 63, and a wheel face film 60 located outside one of the first base films 61 closest to the external environment 3. The strengthening film is located between the first base film 61 and the rough surface film 60, and the reflective film 69 can reflect light. Before the thermal energy advances to the low-radiation film 63, it will first be reflected back into the space 4 by the reflective 10-radiation film 69, so that the thermal energy that can enter the low-radiation film 63 through the reflective film 69 is greatly reduced. However, under the prevention of the low-emissivity film 63, the thermal blocking layer 66, the thermal effect layers 67, and 67 'are stacked on top of each other, so that the thermal blocking layer 66 and the thermal effect layer 67 can be passed smoothly. The thermal energy of ， 67, is very low. Each time the thermal energy passes through one of the layers, its conduction efficiency is partially reduced. Of course, the heat blocking layer 66 and the heat effect layers 67 and 67 ′ can also be staggered, which can also reduce the heat conduction efficiency. The most special feature of this embodiment is that the rough mask 60 can increase the total light incident surface area, so that the low heat loss multi-layer air cell plastic sheet 6 is better than the first two. The embodiment can introduce more sunlight into the space during the day 4 In order to quickly increase the temperature in the space 4, the sugar mask 60 can radiate a small amount of heat energy from the heat-blocking layer 66, the heat-effect layer 67, 67, before the sun shines again the next day. The large surface area of the rough mask 60 assists the faster diffusion of thermal energy to the surroundings, so the third preferred embodiment is particularly suitable for cold 13 200410819 玖, description of the invention (1Θ) in the zone 'fast absorption of thermal energy into the space during the day 4 In order to increase the temperature in the space 4, the minute amount of heat energy transferred from the space 4 after sunset can dissolve the snow accumulated on the plastic sheet of the low-heat-loss multi-layered air cell 6 to avoid heavy snow pressure on the low-heat loss compound Layer of air chamber plastic cloth, which destroys its structural strength and tension, in addition, because a part of the thermal energy is reflected back into the space 4, the air adjacent to the reflective film 69 is not easily caused by the low temperature. Condensation Condensation and dripping of water are formed on the reflective film 69
