Small/ Mini cold storage
Small cold storage is generally divided into indoor type and outdoor type. 1. The ambient temperature and humidity outside the cold storage: the temperature is +35 ℃; the relative humidity is 80%. 2. The set temperature in the cold room: fresh-keeping cold room: +5~-5℃; refrigerated cold room: -5~-20℃; low temperature cold room: -25℃ Class, J-class cold storage: +15 ℃. 4. The effective stacking volume of the assembled cold storage is about 69% of the nominal volume, and it is multiplied by a correction factor of 0.8 when storing fruits and vegetables. 5. The daily purchase volume is 8-10% of the effective volume of the cold storage.
The air-cooled unit is the preferred form of small cold storage, which has the advantages of simplicity, compactness, easy installation, convenient operation, and less auxiliary equipment. This kind of refrigeration equipment is also relatively easy to see. The refrigerator of the refrigeration unit is the heart of the refrigeration equipment. Common compression refrigerators are divided into open type, semi-closed type and fully closed type. The fully enclosed compressor has small size, low noise, low power consumption, high efficiency and energy saving. It is the first choice for small refrigerators. It is an air-cooled refrigeration unit mainly composed of a fully enclosed compressor. It can be made into a form like a split air conditioner and mounted on the wall. The best fully enclosed refrigeration compressors on the market are imported from developed countries or sino-foreign joint venture refrigeration equipment products are more reliable in quality, but the price is more than 50% higher than that of domestic compressors, which is more suitable for small urban cold storage refrigeration equipment. Design points of small-scale cold storage Small-scale prefabricated cold storage with cold storage temperature below 0 degrees (-16 degrees) needs to set up 10# channel steel overhead on the ground (under the storage board) to make it naturally ventilated. There are two common construction methods for cold storage projects, one is the prefabricated cold storage project, and the other is the civil cold storage project. Most of the civil cold storage projects use PU polyurethane spray foam as the thermal insulation storage board. The selection of refrigeration equipment for cold storage projects mostly uses Freon refrigeration units, large cold storages are mostly water-cooled, and small cold storages are multi-purpose air-cooled units; imported German Bitzer cold storage refrigeration units and French Miyule units, running smoothly, low energy consumption, low failure rate , is the preferred unit for cold storage. It is very important to pay attention to whether the refrigeration equipment of the cold storage project is reasonably configured. This is because a Refrigerating Unit with reasonable matching and reliable performance can not only meet the refrigerating capacity of the cold storage required by the product and the requirements of the storage refrigeration process, but also save energy and have a low failure rate. Some enterprises and individuals who want to build cold storages blindly pursue low prices, ignoring whether the matching of cold storage equipment is reasonable, resulting in the failure to achieve the cooling effect after use. Reasonable setting and matching of refrigeration equipment for cold storage projects may increase investment when building cold storage, but in the long run, it saves a lot of money and effort. The after-sales service of cold storage equipment is also very important, as is the operation and maintenance of cold storage equipment and technical services. The vast number of warehouse construction enterprises should investigate various aspects before building a cold storage, listen to the opinions of other enterprises on the configuration of cold storage refrigeration equipment, and finally determine a practical cold storage plan. Build your own cold storage with a high starting point and high standards, and strive for the best benefits for yourself.
