Talking about the characteristics of water-cooled screw chillers

The water-cooled screw chiller is a central air-conditioning product that uses water as the cooling medium. Compared with the air-cooled unit with the same cooling capacity, its condenser and evaporator are made of special high-efficiency heat transfer tubes, so the structure is compact and the volume is Small size, high efficiency, but also because of its beautiful appearance, stable performance, stable operation, wide range of uses and other advantages, it is popular with everyone, and it is also very suitable for central air conditioning systems and process chilled water systems. However, many people do not understand its composition, so let’s give you a brief introduction.

1. The water-cooled screw chiller is composed of a semi-hermetic screw compressor, a shell and tube condenser, a filter drier, a thermal expansion valve, a shell and tube evaporator, and electrical control parts.

2. The freezing water temperature range of the water-cooled screw chiller is 3℃~20℃, so it is generally not used in home air conditioning systems, but mostly used in manufacturing or some public places, such as electroplating, plastics, food processing and other industries The refrigeration process requires the use of chilled water, and the areas that require the use of chilled water for centralized cooling in large shopping malls, subways, hospitals and other central air-conditioning projects;

3. The water-cooled screw chiller adopts a liquid crystal display man-machine interface, which is simple and convenient to operate, and the operating status is clear at a glance;

4. Water-cooled screw chiller models have single-compressor or multi-compressor combined refrigeration systems;

5. The structure of the water-cooled screw chiller is an open structure, and the whole structure is simple. The operation of the unit can be checked at any time, and the installation and maintenance are very simple.
