氧化冷水機間接冷卻與直接冷卻的區別

2022-11-16

1. 直接冷凍的制冷原理和方式

冷卻塔底盆的水經水泵送至冷水機冷凝器冷卻,再回流冷卻塔進行噴涂。當水被冷卻塔頂部的風扇冷卻后,回流到冷卻塔底部的水池中,重復這個操作。同時,冷凝器中的制冷劑被液化,然后在冷槍中流入蒸發器進行蒸發。蒸發過程中吸收熱量,使冷槍中的硫酸(浴液)得到冷卻。冷卻后的硫酸通過水泵輸送到電鍍(氧化)槽,這是一個循環過程。

2. 間接制冷的原理和方式

冷卻塔底盆的水通過水泵輸送到冷水機冷凝器,對冷凝器進行冷卻。當水流回冷卻塔進行噴涂時,由冷卻塔頂部的風機進行冷卻,再流回冷卻塔底部盆。同時,冷凝器中的制冷劑被液化,然后流入水箱中的蒸發器進行蒸發。在蒸發過程中,熱量被吸收,從而使水箱中的水冷卻。冷卻水通過水泵(中間是分開的,一邊是水,一邊是硫酸)輸送到熱交換器,再通過換熱過程冷卻硫酸,這是一個循環過程。本產品的優點是安裝方便,使用壽命比直接冷凍更長,酸堿不易腐蝕冷水機。

陽*氧化冷水機間接冷卻與直接冷卻的區別

1. 標準冷水機的溫差為5度(20度減少15度)。如果一臺10馬力冷水機的標準冷水機流量為每小時5立方米。

2. 當你試冷水機時,你不能只看冷水機的流量,還要看你需要多少溫度。如果你嘗試的溫度從28度降低到7度,如果溫差大,每小時的冷凍水流量將從3.5立方米降低到1立方米以上。
