There are some differences in the principle of refrigeration and working methods of air-cooled screw-type cold water machines and air-cooled cold water machines. It is mainly reflected in the type of compressor and refrigeration method:

1. Compressor type:

Wind-cold screw-type cold water machine: Use screw compressor as the core component of the refrigeration system. The screw -type compressor compress the refrigerant through the rotation of the screw, which has efficient and stable refrigeration performance and is suitable for a large refrigeration system.

Cold-cold cold water machine: Usually a reciprocating compressor or screw compressor. Compared with the screw -type cold water machine, the type of compressor of the air-cooled cold water machine may be more diverse, but in some cases, the reciprocating compressor may be lower than the screw compressor, but the efficiency is usually lower.

2. Refrigeration method:

Wind-cold screw-type cold water machine: Use a fan to flow the air over the condenser, so as to cool the refrigerant and distribute the heat into the environment. This method can save water resources and suitable for the scene of water -free cooling system.

Cold-cold cold water machine: It also uses a fan to flow the air over the condenser, but its compressor type may not be limited to screw type, which can be duplex. This method can also distribute heat into the environment, but in some cases, more water resources may be needed to maintain the cooling effect.

In summary, the air -cooled screw -type cold water machine has some differences in the type and cooling method of the compressor and the cooling method. Screw -type cold water machines usually have higher energy efficiency and stability, suitable for the requirements of large refrigeration systems, while air-cooled cold water machines may have some advantages in the cooling method and cost, suitable for the needs of small and medium-sized refrigeration systems.
