The main difference lies in the dry evaporator freon refrigerant flow in the pipe, and the refrigerant contained in the tube flow. After throttling the liquid Freon from the lower side of the end cap into the evaporator, after several processes leads from the upper end cap, the refrigerant flows in the tube with the air conditioning evaporator industrial continuous evaporation, so a part of the wall of the steam occupied, so it's not as effective as heat flooded. However, it has no effect on the evaporation temperature of the liquid column, and the high flow rate due freon (≥4m / s), the oil return is better. Furthermore, since the tube is filled with a large number of secondary refrigerant, thereby slowing the risk of frost. The amount of such charge within the evaporator refrigerant just flooded the 1/2 ~ l / 3 or less, it is called "dry evaporator." 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, easy to make Trane air conditioning evaporator, dry consume less storage within the warehouse due to non-packaged foods. However, the lower row of tubes finned heat transfer coefficient of air-conditioning evaporator, and the operation is difficult when defrosting 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.
