消費(fèi)者一般在購買風(fēng)幕柜都存在這樣的疑慮，一臺(tái)好的風(fēng)幕柜和一臺(tái)價(jià)格相差很多的風(fēng)幕柜的區(qū)別在哪？貴在哪里，差在哪里！下面雪銳龍冷鏈設(shè)備給大家詳細(xì)的講解一下。
第一點(diǎn)，質(zhì)量好的風(fēng)幕柜技術(shù)參數(shù)都是完全符合國際標(biāo)準(zhǔn)生產(chǎn)的，經(jīng)國家質(zhì)量技術(shù)監(jiān)督機(jī)構(gòu)歷年來多次抽檢全部合格。
第二點(diǎn)，質(zhì)量好的風(fēng)幕柜的工作溫度以有利食品儲(chǔ)藏或保鮮的最適宜溫度區(qū)分，風(fēng)幕柜適用植物性食品，可以確保食物中所含的汁液不低于凍結(jié)點(diǎn)并保持其新鮮狀態(tài)。冷凍柜溫度為-18攝氏度,用該溫度儲(chǔ)藏食物其保質(zhì)期限長達(dá)1個(gè)月。質(zhì)量好的冷藏展示柜不僅按標(biāo)準(zhǔn)保證風(fēng)幕柜的溫度符合要求，還通過采用異形蒸發(fā)管并匹配適宜制冷量的機(jī)組，使質(zhì)量好的風(fēng)幕柜制冷速度更快。
第三點(diǎn)質(zhì)量好的風(fēng)幕柜全部蒸發(fā)管都采用質(zhì)量好的銅盤管并處理成寬面異形。不銹鋼板表面光潔好，整板厚薄均勻，采用適當(dāng)?shù)暮穸燃缺ＷC使用壽命長久，又使風(fēng)幕柜外觀平整結(jié)實(shí)。銅管比鋁管或復(fù)合管的傳冷效果好，耐腐蝕性更好，質(zhì)量好的銅盤管具有管內(nèi)潔凈度高，管接頭少的優(yōu)點(diǎn)，可有效防止制冷系統(tǒng)內(nèi)漏或堵塞的故障。將圓形管處理成矩形，使蒸發(fā)管與傳冷的內(nèi)膽接觸由點(diǎn)接觸變成面接觸，擴(kuò)大了傳遞面積，能加快制冷速度。
第四點(diǎn)風(fēng)幕柜生產(chǎn)過程中保溫層絕熱性能的優(yōu)劣既是風(fēng)幕柜重要的質(zhì)量指標(biāo)，更是風(fēng)幕柜使用經(jīng)濟(jì)性的一個(gè)重要因素。為達(dá)到良好的絕熱性能，必須選擇適當(dāng)?shù)脑�，控制容重和泡孔直徑在最佳范圍�?nèi)。因此只有采用能調(diào)控料溫，配合專用夾具，掌握成熟發(fā)泡工藝，才能生產(chǎn)出保溫效果好的風(fēng)幕柜。
第五點(diǎn)質(zhì)量好的風(fēng)幕柜的柜體的結(jié)構(gòu)堅(jiān)固度如何，直接關(guān)系展示柜使用年限的長短。質(zhì)量好的風(fēng)幕柜的外殼與內(nèi)膽之間有整體角鋼架支撐，其作用相當(dāng)于水泥預(yù)制板中安放有鋼筋，堅(jiān)固度大增。門框在內(nèi)全部焊接成形后，整體一次性發(fā)泡成形，避免了因門框拼裝不牢，柜門容易脫落的缺陷。整體鋼架一次成形優(yōu)點(diǎn)明顯，為什么其它廠家不采用呢?因?yàn)閵A具要求復(fù)雜，裝夾難度大，不是處處為消費(fèi)者利益著想的廠家，決不可能采用這種結(jié)構(gòu)和工藝。
Consumers in the purchase of general air curtain have such doubts, a good air curtain and a lot of the price difference between the air curtain cabinet in which the difference? Where, where the poor! The snow cold chain equipment dacentrurus give you a detailed explanation of the.
First, the quality parameters of the wind curtain cabinet are all in line with the international standard production. The quality inspection agency has been qualified for many times in the past years.
The second point is that the working temperature of the good wind curtain cabinet is distinguished from the most suitable temperature for favorable food storage or preservation. The wind curtain cabinet is suitable for plant foods, which ensures that the juice contained in the food is not lower than the freezing point and keeps its fresh state. The temperature of the freezer is -18 degrees centigrade, and the shelf life of the stored food at that temperature is 1 months. The refrigerated display cabinet with good quality not only meets the requirements of the air curtain cabinet according to the standard, but also makes the air curtain cabinet with good quality refrigerate faster by using the special shaped evaporation tube and matching the suitable refrigerating volume.
Third good quality air curtain tube are all evaporated using good quality copper tube and processed into wide profile. The surface of the stainless steel plate is bright and clean, the whole plate is thick and thin, and the proper thickness can not only guarantee the long service life, but also make the appearance of the air curtain flat and strong. Brass than aluminum or composite tube heat transfer effect, better corrosion resistance, good quality of copper tube in tube with high cleanliness, pipe joint less advantages, can effectively prevent the failure of internal leakage or blockage of the refrigeration system. The circular tube is treated as a rectangle, which makes the contact of the evaporator and the cooling inner contact from the point contact to the surface, enlarges the transfer area and speeds up the cooling rate.
The insulation performance of insulation layer in the production of fourth point wind curtain cabinet is not only an important quality index of wind curtain cabinet, but also an important factor of the economy of air curtain cabinet. In order to achieve good insulation performance, appropriate materials must be selected to control the bulk density and the diameter of the bubble hole in the optimum range. Therefore, only by controlling the temperature of the material, matching the special fixture and mastering the mature foaming process can we produce the air curtain with good heat preservation effect.
Fifth points of good quality of the windscreen cabinet structure of the sturdy, directly related to the length of the service life of the display cabinet. There is an integral angle steel frame support between the shell of the high quality air curtain cabinet and the inner liner, which is equivalent to the reinforcement of the cement prefabricated plate, and the strength increases greatly. After the whole welding of the door frame, it is formed as a whole at one time, avoiding the defect that the door frame is not fastened and the door is easy to fall off. The advantages of the whole steel frame at one time are obvious. Why do not other manufacturers adopt it? Because the fixture is complicated and difficult to assemble, and it is not a factory that is always considering the interests of consumers. It is impossible to adopt this structure and technology.
