機組說明 Unit description
傳統載冷劑制冷系統多用于干式蒸發，干式蒸發系統簡單，氟充注量少，初期投資成本低，在需冷量較小的系統，干式蒸發是不錯的選擇。但干式蒸發的致命缺陷就是換熱效率低，在需冷量較大的系統體現的尤為明顯。故我公司經過大量研究實踐，研發出浮頭式滿液鹽水機組。利用浮頭式滿液蒸發器換熱效率高的優勢減小兩次換熱效率損失。蒸發溫度和冷間溫度溫差控制在8K以內。
The traditional refrigerant refrigerating system mostly uses on dry evaporate, dry evaporate has a simple system, charge quantity of fluorine is little, and has a small initial investment. It’s a good choice for little cooling capacity needed system. While the critical defect of dry evaporate is the low heat transfer efficient, it is obviously in those system that cooling capacity is lager. Thus our company developed the floating type flooded secondary refrigerant refrigerating unit through a large number of research and practice. Use the high heat transfer efficient of floating flooded evaporator reduce the efficient loss of twice heat exchange. The temperature difference between evaporation temperature and the cooling room temperature can be controlled within 8K.
工程應用 Unit description
l 冷庫氨改氟：隨著社會的進步，政府和公眾對安全生產的重視程度越來越高。具體到制冷行業內來說，由于原先的氨庫存在著設計缺陷、施工質量、設備年久失修，保養不到位等一系列問題，導致了在國內發生氨庫爆炸，氨液泄漏等嚴重事故，給當地民眾造成了嚴重后果。隨后國家馬上出臺改造治理一系列存有潛在安全隱患的氨庫工程。因此新建氨庫從前期的審批、中期對設計施工的監管和后期的運行管理均具有一定的難度。故氨庫改氟庫用我滿液式機組，庫內無縫鋼管蒸發器可保留，直接走鹽水載冷劑，能夠大大降低改造成本，加裝儲能灌，合理的利用“谷電”避開“峰電”，降低運行成本，已有大量成功案例。
l 花色線氨改氟：冰激凌花色線氨改氟專用機組。對于冰激凌冷飲廠花色線氨改氟，只需將機組更換，實現無縫對接，大大降低改造成本和改造時間。在全國已有大量成功案例。
l Ammonia replacement fluorine of cold storage: with the development of society, the attention of safety production by the government and public is increasingly high. Concrete to the cooling industry, as the series problem of design flaw, low construction quality and maintenance lacking of ammonia refrigerating cold storage, caused explode and leakage etc. serious accident and leaded a grave consequences to the local public. Soon the government introduced policies to remould the ammonia refrigerating cold storage that exists potential safety hazard. Thus it is difficult from the approval of earlier stage, design and construction supervision of middle stage and operation management of last stage for new ammonia refrigerating cold storage. Our flooded secondary refrigerant refrigerating unit can remain the original pipe in cold store, and use the secondary refrigerant replace the ammonia can reduce the cost and time of improvement greatly. The system has a large capacity storage tank of cold energy, using "valley electricity", avoiding "peak power", reducing the operating cost. Many successful cases has been applied.
l Colored streak: ice cream colored streak replacement of ammonia by fluorine dedicated unit. The replacement of ammonia by fluorine for colored streak ice cream producing factory, only change the original unit can realize seamless joint, and greatly reduce the cost and time of improvement. Many successful cases has been applied throughout the country.
