Row tube refrigerator: temperature in 18 ~ 20 degrees Celsius.Control in large cold way, civil engineering is the most common type of cold storage refrigeration system, the top row tube is cooling pipe installed on the top of the refrigerator, the installation due to the exhaust pipe from the ground, do not take up the inventory space, and not easy to knock against, the use of safe, exhaust pipe produced by the air conditioning top-down natural convection, uniform temperature inside.Row tube refrigerator in refrigeration work, located at the top of the rolls tube of the surrounding air, the first row of pipe cooling, the cooled air are smaller and the proportion of increase, affected by the gravity of natural decline, while the food and the surrounding air temperature is higher than the former, the proportion of less than the former, natural increase, result in the cold storage within cold and hot air natural convection, can not help but is beneficial to the cooling of food, and air flow rate is low, the loss of dry food is light, is advantageous to the food storage quality is suitable for storage: frozen meat, seafood, ice cream, buns, frozen fruit, frozen goods and so on.
