The main features of the vertical condenser are: Due to the high cooling flow and flow rate, the heat transfer coefficient is high, generally about K = 600 ~ 700 (kcal / m2? H? ℃). Vertical installation covers small areas, and can be installed outdoors. Cooling water flow directly and have high flow rate, so not need high water quality, the general water can be used as cooling water. Scales in pipe can be easy removed, and do not have to stop the refrigeration system work.But in the vertical condenser, the rise temperature of cooling water is generally only 2 ~ 4 ℃, logarithmic average temperature difference is generally about 5 ~ 6 ℃, so need much water. And because the equipment is placed in the air, the tube is susceptible to corrosion and is easier to find its leaking.
