目前,尚有不少水冷式制冷机在中小型冷库、冷藏箱中使用。其特点是冷却效果比风冷好。存在的问题是:一、浪费水太多;二、冷却水一但中断,机器因压力过高而易损坏。为此,我们对该制冷机进行了改进。具体办法是在冷却水的管道上加一个停水保护的水压开关和一个节水电磁阀。经使用效果良好,不但解决了制冷机因停水而被损坏的问题,而且又节约冷却用水。具体方法如下:
At present, there are still many water-cooled refrigerators used in small and medium-sized refrigerators and refrigerators. Its characteristic is that the cooling effect is better than air cooling. The problems are: First, waste too much water; Second, once the cooling water is interrupted, the machine is easily damaged due to high pressure. To this end, we have improved the refrigerator. The specific method is to add a water protection water pressure switch and a water saving solenoid valve to the cooling water pipeline. The use of good results not only solved the problem of the refrigerator being damaged due to water stoppage, but also saved cooling water. The specific method is as follows:
