控制溫度的櫃子該如何實現？

時間：2020-09-01 作者：點擊：

鑒于日常生活中部分物品的儲存並非只是單純的存進冰箱就能解決大部分問題，部分物品如膠卷，菲林，ic芯片，醫藥品這類在儲存是就不能簡單的扔進冰箱裏，這一類物品在儲存時更多的是需要考慮吧溫度控制在某一個區間裏，因此帶有溫度控制概念的櫃子這裏理念油然而生，那麽該怎麽實現帶溫度控制的櫃子呢？

實現溫度控制功能首先需要了解溫度這一概念，必須明確的一點是溫度變化屬于分子間的運動部分由溫度高的一方向溫度低的一方轉移，溫度在傳遞時不需要介質，也不存在溫度不能傳遞的情況出現。動手能力較高的雪茄愛好者在制作自用雪茄保存櫃時可能會想到使用聚苯乙烯泡沫塑料（即泡沫材料）進行密封隔熱。但即使使用聚苯乙烯泡沫塑料也無法完全阻斷溫度傳遞，自制雪茄保存櫃必須內置降溫組件才能保證櫃內長期持續的低溫。同理可以推導帶溫度控制的櫃子其自身除了具備嚴格的隔熱層之外也必須擁有降溫設備才能保證溫度的穩定性進而不會被環境溫度同化

圖爲華宇現代某款恒溫櫃，其溫度控制範圍在0-30攝氏度之間，誤差範圍在±0.5攝氏度左右

實現溫度降低的方法目前主流的水冷風機，蒸發型空調，水簾等傳統利用蒸發效應降溫等節能環保機器，也有空調式內置壓縮機實現降溫功能，傳統水蒸發式降溫容易導致櫃內濕度過高，在儲存某些ic芯片，光學鏡頭，膠卷菲林，電子元器件時高濕度容易引起發黴等現象，因此用于商業的控制溫度的櫃子在實現降溫功能時出于對産品的保護功能不能采用蒸發式降溫方式而應該選擇內置空調來實現降溫

有降溫系統對應的肯定是也有加溫系統，和降溫系統不同的是加溫系統在實現其功能時難度遠遠低于降溫系統，加溫櫃在功能方面是不如控制溫度的櫃子，但需要注意的是加溫需要勻稱，參考部分廉價防潮櫃設計其加溫模塊在櫃內及其容易導致附近産品遭到高溫烘烤導致過分幹燥斷裂。由此可以得出加溫系統和降溫系統和産品隔離是一種更優解的設計方式

結合上述觀點可以得出如果需要實現櫃子能自由控制溫度功能，其自身必須具備完整的隔熱層配置減輕櫃內受到環境溫度的影響，同時還應該具備加溫組件和降溫組件來主動調節櫃內溫度，這樣一台能控制溫度的櫃子的設計方案皆可以實現了

PART OF THE WALL OF THE PEKIN. PART OF THE WALL OF THE PEKIN. "But you say if this scheme works you lose by it. What will you lose?" "What are you playing at?" the Doctor demanded, glancing at the crumpled bonnet of his car. "It's a wonder I didn't kill you." By this time the Doctor's condition of hysteria had given way to a sort of desperate recklessness. He had somehow to restore the Clockwork man to some semblance of passable humanity. He pressed stops and twisted hands[Pg 165] with an entire disregard for the occasional instructions bellowed at him by the unfortunate object of his random experiments. He felt that the very worst could scarcely surpass what had already taken place. And it was obvious that the Clockwork man had but the haziest notions about his own mechanism. Evidently he was intended to be adjusted by some other person. He was not, in that sense, autonomous. Master Jervie and that editor man were right; you are most convincing This insult roused the fiery blood of Spain. The king and queen were excited to paroxysms of rage. They told Mr. William Stanhope that, in future, they would put confidence in no prince except his master, nor admit any one else to mediate for them in their negotiations. But George refused to break with France on their account, and ventured to remind Philip that he himself stood greatly in need of the alliance with France. Blinded, however, by their wounded pride, the King and Queen of Spain now turned their anger against England. They recalled their plenipotentiaries from the Congress of Cambray, which was sitting to settle the affairs of Europe, and professed their readiness to abandon all their hostility to the Emperor of Germany, and to concede all that they had so long demanded from him, on condition that he entered into a close alliance with them against France and England. They sent back to France the widow of the late Don Louis, and also Mademoiselle Beaujolais, another daughter of the late Regent Orleans, who had been contracted to Don Carlos. "You do not know me?" asked the latter. HoME 妞妞2014改成妞妞2015 ENTER NUMBET 0010aab59.com.cn
