求翻译：当场地长度比较短，而冷却能力又要求比较大时，需要采用回转式胶片冷却机，此类型胶片冷却机在长度方向节省了空间，且能达到理想的冷却效果。是什么意思？

To relatively short length of the spot, and they require a relatively large cooling capacity, the need to use rotary film cooling machine, this type of film cooling machine saves space in the length direction, and can achieve the desired cooling effect.

When venues are relatively short length, and cooling capacity also requested a comparison, there is a need to use when the film cooling machines, rotary-type film cooling machines in the direction length save space, and is able to achieve the desired cooling effects.

The length quite is on the scene short, when cooling capacity requests quite in a big way, needs to use the rotation type film refrigerator, this type film refrigerator has saved the space in the length direction, also can achieve the ideal cooling effect.

When the venue length very short, and the cooling is required when comparing large requires a film cooling for rotary machines, this type of film cooling in the length direction saves space, and be able to reach the desired cooling effect.

To relatively short length of the spot, and they require a relatively large cooling capacity, the need to use rotary film cooling machine, this type of film cooling machine saves space in the length direction, and can achieve the desired cooling effect.
