Vertical tube evaporator coil and the common refrigerant in the evaporator tube refrigerator evaporator, the entire group immersed in the evaporator tubes containing refrigerant cabinets loaded (or pool, bath), in order to ensure the refrigerant contained in tank at a constant speed loop, inside welded longitudinal bulkhead and equipped with a propeller stirrer. Contained refrigerant flow rate is generally 0.3 ~ 0.7m / s refrigerator evaporator price, in order to enhance heat transfer. Both evaporator can be used only open-cycle system, it must be non-volatile secondary refrigerant substance, commonly used is salt and water. As with brine evaporator tube susceptible to oxidation, and hygroscopic brine leaving concentration. Both the evaporator can be directly observed in the secondary refrigerant flow brass refrigerator evaporator, ammonia is widely used as a refrigerant brine cooling system. Cooled exhaust pipe is a used evaporator cooling air. Widely used in a low temperature refrigerator, the refrigerant flows in the discharge tube was cooled and evaporated, the outer tube as a heat transfer medium is cooling air for natural convection. The biggest advantage cooled exhaust pipe is simple in structure, easy to manufacture, consume less dry storage within the warehouse due to non-packaged foods. But calandria lower heat transfer coefficient, and when defrost operational difficulties, is not conducive to automation. For direct ammonia cooling systems seamless welded, using a light pipe or coiled finned tube; Freon system, mostly using around the chip or set piece brass finned tube group. Refrigerator evaporator manufacturing | evaporator (certified) | refrigerator evaporator is provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
