Description of the Invention: [Technical Field] The present invention relates to a high-pressure air freezing and dehumidifying system, and more particularly to a composite type in which a plurality of parallel frosters are connected in series with a pre-dehumidifier. High pressure air refrigeration dehumidification system. [Prior Art]

空氣純化是許多製程必備的程序，用以獲得含水率非常低（例如0.01%)的乾燥空氣，進入分子篩選薄膜後，將 N2及〇2分別取出，而一些較大分子例如C〇2，被排在濾膜之前，但分子較小卻非惰性之水蒸氣，對製程有許多不良的影響，無法以分子膜篩選，須以除濕或冷凍結霜的方式，將水分子自濕空氣中取出，此為製程冷凍之空氣乾燥技術。若採用冰點以上蒸發器盤管低溫表面空氣中水蒸器凝結之除濕方法，由於熱質傳的效率限制，使得濕空氣的含水率仍然很高。當空氣壓力在700kPa時，蒸發器表面溫度為5 °C時，以熱力學計算空氣通過的理想濕度比（humidity ratio)約為0.00086，當蒸發器表面溫度為-15°C時，理想濕度比約為0.00016，僅為前者的1/5，如果表面溫度降至-25 °C時，理想濕度比更可達到0.000053。因此以冷凍除濕的方法，空氣處理後的含水率可以低於1/10000。然而冷凍除濕的缺點是當長期運轉時，需要定時除霜，例如24小時運轉需除霜一至三次，除霜週期是以結霜量來決定。 0956-A21824TWF(N2)；P55950041TW；chentf 5 1303581 最早期的高壓空氣冷凍乾燥，經常以一厚重腔體，内部裝置所有除濕或結霜用盤管，如英國專利GB893773所揭露者，這種設計方式是以空氣壓縮機的壓縮腔及除濕裝置整合在一起，缺點是空壓機與除濕系統共構情況嚴重，只要一個零組件故障，就要進行腔體拆卸維修，另外體積重量過大、不容易進行彈性組合。Air purification is a must-have procedure for many processes to obtain dry air with very low moisture content (eg 0.01%). After entering the molecular screening membrane, N2 and 〇2 are separately taken out, while some larger molecules such as C〇2 are Before the filter, but the small but non-inert water vapor has many adverse effects on the process, it cannot be screened by molecular membranes. The water molecules must be taken out of the humid air by means of dehumidification or freezing frost. This is a process air freezing technology. If the dehumidification method of water vaporizer condensation in the low-temperature surface air of the evaporator coil is used above freezing point, the water content of the humid air is still high due to the efficiency limitation of the heat mass transfer. When the air pressure is 700 kPa and the evaporator surface temperature is 5 °C, the ideal humidity ratio of the air passing through the thermodynamic calculation is about 0.00086. When the evaporator surface temperature is -15 °C, the ideal humidity ratio is about It is 0.00016, which is only 1/5 of the former. If the surface temperature drops to -25 °C, the ideal humidity ratio can reach 0.000053. Therefore, in the method of freezing and dehumidifying, the moisture content after air treatment can be less than 1/10000. However, the disadvantage of freezing and dehumidifying is that when it is operated for a long time, it needs a time defrosting. For example, a 24-hour operation requires defrosting one to three times, and the defrost cycle is determined by the amount of frosting. 0956-A21824TWF(N2); P55950041TW;chentf 5 1303581 The earliest high-pressure air freeze-drying, often with a thick cavity, internal unit for all dehumidification or frosting coils, as disclosed in British Patent GB893773, this design approach The compression chamber and the dehumidification device of the air compressor are integrated. The disadvantage is that the co-construction of the air compressor and the dehumidification system is serious. As long as one component fails, the cavity is disassembled and repaired, and the volume is too heavy and is not easy to carry out. Flexible combination.
