Screw chiller summer use method

Screw chiller summer use method

In the hot summer days, the screw chiller is used more frequently. If you want the unit to operate normally, you need to pay attention to the following points. 1. Screw-type chillers are used more and more frequently in summer. Many customers who have used them for two years and three years may not have maintained the screw chillers. Maintenance and car oil change is a reason, used for a long time, the oil will be carbonized after high temperature, easy to cause oil return is not smooth, the filter is dirty, then the screw chiller should be maintained. The maintenance of the screw chiller will be better, the service life will be longer, the performance will be more stable, and it will be more energy efficient. 2, the most popular air-cooled screw chiller in summer is the high-pressure alarm, internal protection. Because the ambient temperature in summer is relatively high, heat dissipation is often not ideal. Therefore, the air-cooled condenser should be cleaned to ensure better heat dissipation. The main reason for the protection inside the machine is also the problem of heat dissipation, so the screw chiller should be maintained. 3, water-cooled chiller is the most prone to high-pressure alarms in the summer, the internal protection, the exhaust temperature is too high. The main reason may be that the water temperature of the cooling tower is too high, and the dirty and fouling of the water pipeline causes the condenser of the screw chiller to fail to achieve the desired heat exchange effect, resulting in high pressure and high exhaust gas temperature. It is necessary to clean the cooling tower and the water-cooled condenser. The main treatment method is to clean the condenser pipeline, use a special brush to clean the scale in the pipeline with a professional scale treatment agent, and filter on the cooling water. Also remove and clean, filter to replace 4, good customers usually clean the filter once every two months or so, cleaning the pipeline once every six months, in order to achieve the best operating conditions of the unit. Often such customers will allow the screw chiller to operate normally and will be more energy efficient.
