水冷式水从金属移去热量要比空气快得多,这样对于相同的容量,水冷冷凝器比风冷冷凝器要紧凑得多水具有这种增加传热率的优点是由于改善了表面散热系数。由此,水冷冷凝器与风冷冷凝器相比,其工作时的冷凝制冷剂和水之间的温差比风冷冷凝器工怍时的冷凝制冷剂和周围空气之间的温差低,风冷冷凝器的温差通常为30℉(16.67℃),
Water-cooled water removes much more heat from the metal than air, so water-cooled condensers are much more compact than air-cooled condensers for the same capacity. The advantage of this increased heat transfer rate is the improved surface heat dissipation coefficient . As a result, the temperature difference between the condensed refrigerant and water during operation of the water-cooled condenser is lower than that of the air-cooled condenser over the temperature difference between the condensed refrigerant and the ambient air when the air-cooled condenser is operating, The temperature difference of the condenser is usually 30 ° F (16.67 ° C)
