空调系统的减振设计对消声和减振有哪些措施？
What measures does the vibration reduction design of the air conditioning system have for noise reduction and vibration reduction?

1.在空调系统中，空调机组应最好采用弹簧减震器,按机组功率及安装位置不同选择不同的挠度的弹簧减震器,大功率设备可选用40MM挠度的弹簧减震器,较小功率空调主机可使用25MM常规弹簧减震器。同空调主机,风机水泵也应用弹簧减震器做减振处理.并且适情况增加减震基座.除了对风机、水泵等产生振动的设备设置弹性减振支座外，还应在风机与风管之间采用软管链接，风管接头宜采用人造材料或帆布材料制作。6号以下风机，软管的合理长度为200mm；8号以上的风机，软管合理长度为400mm.
1 in the air conditioning system, the air conditioning unit should be the best use of spring shock absorber, according to the unit power and installation position of different choice of different deflection of the spring shock absorber, large power equipment can choose the 40MM deflection of the spring shock absorber, smaller power air conditioning host can use 25MM conventional spring shock absorber.In addition to the vibration of the fan, water pump and other vibration equipment set up elastic vibration damping support, should also be used between the fan and the duct hose link, duct joint should be made of artificial materials or canvas materials.For fans below no.6, the reasonable length of the hose is 200mm;For fans above no.8, the reasonable length of hose is 400mm.

2.水泵、冷水机组、风机盘管、空调机组等设备与水管之间用软管连接，不使振动传递给管路。软管有两类：橡胶软接管和不锈钢波纹管。橡胶软接管隔振减噪的效果很好，缺点是不能耐高温和高压，耐腐蚀性也差。在空调与采暖的水系统中多用橡胶接管。不锈钢波纹管能耐高温、高压和耐腐蚀，但价格较贵，一般用于制冷剂管路的隔振。
2. Connect water pumps, chillers, fan coils, air conditioning units and other equipment with water pipes with hoses, so that vibration is not transmitted to the pipes.There are two types of hoses: soft rubber nozzles and stainless steel bellows.Rubber soft noise-isolation effect is very good, the disadvantage is not able to high temperature and high pressure, corrosion resistance is also poor.Rubber nozzles are used in air conditioning and heating water systems.Stainless steel bellows can withstand high temperature, high pressure and corrosion resistance, but the price is more expensive, generally used for refrigerant pipeline isolation.

3.在管路的支吊架、穿墙处使用非燃软性材料填充做减振处理。振动较大的设备吊装时，采用吊式弹簧减震器。
3. Use non-combustible soft materials to fill the support and hanger and through the wall of pipelines for vibration reduction.Vibration of the larger equipment when hoisting, the use of hanging spring shock absorber.

4.选用高效、低噪声水泵、风机，并使水泵、风机在最高效率点附近运行。
4. Choose high efficiency and low noise water pump and fan, and make the water pump and fan run near the highest efficiency point.

5.按噪声标准控制风管、风口风速，以满足房间噪声要求。
5. Control the wind speed of air duct and tuyere according to the noise standard to meet the room noise requirements.

6.空调机房内壁表面贴附吸声材料及吸声孔板，机房门采用消声密闭门，使墙体有吸声能力，等等
6. Sound absorption material and sound absorption hole plate are attached to the inner wall surface of the air conditioning room. The door of the machine room is closed with muffler, so that the wall has sound absorption ability, etc
