Shell-and-tube condensers installed in cold storage are divided into vertical and horizontal types. Vertical shell and tube condenser. Porous tube plates are welded at both ends of the cylinder, and heat transfer tubes are correspondingly arranged in the holes for cooling the refrigerant. Its characteristics are huge structure and many consumables; Cooling water has low flow rate, easy scaling and large consumption, and is suitable for areas with sufficient water sources and poor water quality.
The structure of horizontal shell-and-tube condenser is similar to that of vertical condenser. When the refrigerant is ammonia, the heat transfer tube adopts seamless steel tube, and when the refrigerant is Freon, the heat transfer tube adopts low-ribbed copper tube. Horizontal shell-and-tube condenser has high heat transfer coefficient, less cooling water consumption, but higher water quality requirements, and is widely used in ammonia and Freon refrigeration systems of large, medium and small cold storage.
