How to use small cold storage in summer with good energy saving effect

Summer is the peak period for cold storage installation. When many people in the food-related industries are ready to consider cold storage installation, there are many factors to consider when installing cold storage in summer, especially in terms of energy saving. Cold storage is a building with relatively large energy consumption. Consider energy-saving issues at the beginning of installation, which can help users save a lot of costs in the future. Moreover, the service life of a cold storage is at least 15 years. In this case, energy saving should be a strategic consideration for cold storage installation, and users should give it. Enough attention.

　　 The energy-saving issues to be considered during the installation of small cold storage are mainly refrigeration equipment and refrigeration systems. Many small cold storages mostly use Freon refrigeration systems. This type of refrigeration system has its advantages when used in small cold storages. It has high automation, simple and compact structure, and users prefer it. The units generally use air-cooled condensation, and the ambient temperature is not very high. , The cooling effect is very good.

　　 However, the energy consumption of this kind of refrigeration system in summer is a real headache for many users. In summer, the ambient temperature is very high and the humidity is high. Although the condenser cooling area is designed enough, the ambient temperature cannot be changed, and the exhaust pressure will be particularly high. Especially small high-temperature warehouses, such as the acid storage warehouses used in the slaughter industry, have large quantities of goods, high heat and high cold consumption. Refrigeration efficiency should be greatly reduced, power consumption is large, and cooling is slow. This brings a certain risk to the cold storage friends. Sometimes some users have to take emergency measures, such as watering the condenser. Although the effect is good, after all, the long-term solution to the problem is not only a waste of manpower and financial resources, but also It will also cause corrosion to the condenser and affect its service life.

In view of the above situation, the best way to install refrigeration equipment is to install an "evaporative condenser" (in series), and customize the condenser (self-made if possible) according to the size of the refrigerator, with a cooling area >0.7㎡/hp ( Expanded area of ​​copper tube plus fin area) fin pitch>7mm.

　　 In terms of system installation, the main consideration is whether the selected units are fully matched, whether there is excessive production capacity that causes waste of energy, and the phenomenon of small horse-drawn carts due to insufficient production capacity. For example, the operation of the circulating water pump and the small fan are synchronized with the compressor, and the power of the water pump should not be too large (50W>100W, 220V).
