國(guó)內(nèi)冷庫(kù)的興建在20世紀(jì)80年代有一個(gè)高潮，但是都是粗放式管理，部分冷庫(kù)設(shè)計(jì)不規(guī)范，存在安全隱患。我國(guó)作為食品的生產(chǎn)大國(guó)，小型冷庫(kù)的發(fā)展具有極大空間。小型冷庫(kù)的建造應(yīng)該注意以下幾個(gè)問(wèn)題：
The construction of the domestic cold storage in 1980s has a climax, but the extensive management, some cold storage design is not standardized, there are security risks. China as a food producing countries, the development of small cold storage has a great space. The construction of small cold storage should pay attention to the following questions:
1、冷酷的隔熱材料以前都采用軟木、稻殼等，就目前來(lái)說(shuō)，采用聚氨酯現(xiàn)場(chǎng)發(fā)泡最為合適，由于聚氨酯硬質(zhì)泡沫塑料的導(dǎo)電系數(shù)很小，隔熱層可做得比較薄，這樣可以增加庫(kù)的成本。山東冷庫(kù)造價(jià)
1, the cold heat insulation materials used in the past are cork, rice, etc., at present, the use of polyurethane foam is the most appropriate, due to the low conductivity of polyurethane rigid foam, insulation layer can be relatively thin, so you can increase the cost of the library.
2、在制冷設(shè)備上，采用蒸發(fā)式冷凝器，配備變頻調(diào)速裝置不僅可以省去冷卻塔及水泵及循環(huán)水池投資，還可以節(jié)能省電。
2, in the refrigeration equipment, the use of evaporative condenser, equipped with frequency control device can not only save the cooling tower and water pump and circulating pool investment, but also can save energy.
3、采用“分散式制冷系統(tǒng)”，冷卻設(shè)備由冷風(fēng)機(jī)代替，可以提高冷卻效率。
3, using the "decentralized refrigeration system", cooling equipment, instead of cold air, can improve the cooling efficiency.
最后還應(yīng)注意加強(qiáng)管理人員的安全意識(shí)，注意掃除安全隱患，建立能源站臺(tái)，才能節(jié)省冷庫(kù)造價(jià)。
Finally, we should pay attention to strengthen the management of safety awareness, attention to eliminate safety hazards, the establishment of energy platform, to save the cost of cold storage.
