Zusammenfassung:	The utility model discloses a noise reduction device for a normal-temperature screw water chilling unit. The device comprises a base, a noise reduction cotton structure, a bottom plate and a protection damping structure, the top end of the base is fixedly connected with the noise reduction cotton structure, the inner wall of the noise reduction cotton structure is fixedly connected with the protection damping structure, the bottom plate is arranged in the middle of the noise reduction cotton structure, and the top end of the bottom plate is fixedly connected with a detachable structure. According to the utility model, a power supply is connected; controlling a chiller to start working, when the cooling-water machine makes a sound; when sound is transmitted to the position of the N-shaped sound insulation cotton. According to the noise reduction device for the normal-temperature screw water chilling unit, the noise reduction holes are formed in the middle of the N-shaped sound insulation cotton, the N-shaped s
