一般情況下，小型冷庫(kù)選用全封閉壓縮機(jī)為主。因全封閉壓縮機(jī)功率小，價(jià)格相對(duì)便宜;中型冷庫(kù)一般選用半封閉壓縮機(jī)為主;大型冷庫(kù)選用半封閉壓縮機(jī)，在選用時(shí)，也可考慮選用氨制冷壓縮機(jī)，因?yàn)榘敝评鋲嚎s機(jī)功率大，并可一機(jī)多用，但安裝及管理比較煩瑣。
Under normal circumstances, the selection of small cold storage closed compressor. Because closed compressor power is small, the price is relatively cheap; cold storage is generally used in semi hermetic compressor; large refrigerator using semi hermetic compressor, in the selection, also consider the use of ammonia refrigeration compressor, because ammonia refrigeration compressor power, and the use of a machine, but the relatively cumbersome installation and management.
在冷庫(kù)蒸發(fā)器的選用時(shí)，高溫冷庫(kù)以選用冷風(fēng)機(jī)為蒸發(fā)器，其特點(diǎn)是降溫速度快，但易造成冷藏品的水分損耗;中、低溫冷庫(kù)選用無縫鋼管制作的蒸發(fā)排管為主，其特點(diǎn)是恒溫效果好，并能適時(shí)蓄冷。
In the selection of cold storage evaporator, high temperature refrigerator to choose cooling fan for an evaporator, which is characterized by fast cooling, but it is likely to cause the loss of cold water collection; in cold storage, selection of seamless steel tube is made of evaporative emission control, which is characterized by constant temperature effect, and the timely storage.
冷庫(kù)隔熱材料的選用必須因地制宜，既要有良好的隔熱性能，又要經(jīng)濟(jì)實(shí)用。隔熱材料分幾種類型，一種是加工成固定形狀及規(guī)格的板塊，有固定的長(zhǎng)度、寬度和厚度，可根據(jù)冷庫(kù)庫(kù)體安裝的需要選擇相應(yīng)規(guī)格的板塊，高、中溫冷庫(kù)一般選用10cm厚的庫(kù)板，低溫冷庫(kù)及凍結(jié)冷庫(kù)一般選用12cm或15cm厚的板塊;另一種可以用聚氨脂噴涂發(fā)泡，把材料直接噴到已經(jīng)建成的磚或混凝土倉(cāng)庫(kù)中，定形后既防潮又隔熱。
The selection of heat insulation materials for cold storage must be in accordance with local conditions, not only with good heat insulation performance, but also economical and practical. Insulation materials of several types, one is processed into a fixed shape and specifications of the plate length, width and thickness are fixed, select the appropriate specifications of the plate according to the need of Refrigeratory library body installation, high temperature, cold generally 10cm thick base plate, cold storage and freezing cold storage or general use 12cm 15cm thick plate; another can use spray polyurethane foam, the material is sprayed directly into the already built brick or concrete warehouse, setting both waterproof and heat insulation.
隔熱材料板塊有聚氨脂、聚苯脂等。聚氨脂不吸水，隔熱性較好，但成本較高;聚苯脂吸水性強(qiáng)，隔熱性較差，但成本較低。現(xiàn)代冷庫(kù)的結(jié)構(gòu)正向裝配式發(fā)展，制成包括防潮層和隔熱層的庫(kù)體構(gòu)件，做到現(xiàn)場(chǎng)組裝，其優(yōu)點(diǎn)是施工方便、快速，且可移動(dòng)，但造價(jià)比較高。
The heat insulation material has polyurethane, polyphenyl fat and so on. Polyurethane does not absorb water and has better heat insulation, but the cost is higher; the water absorption of the polyphenyl fat is strong, and the heat insulation is poor, but the cost is low. The structure of modern cold storage is developing in assembly type, and it is made up of the storehouse structure including moistureproof layer and heat insulation layer. It can be assembled on the spot. The advantage is that the construction is convenient, fast and moving, but the cost is relatively high.
