空調(diào)系統(tǒng)的減振設(shè)計(jì)對消聲和減振有哪些措施？
What measures does the vibration reduction design of the air conditioning system have for noise reduction and vibration reduction?

1.在空調(diào)系統(tǒng)中，空調(diào)機(jī)組應(yīng)最好采用彈簧減震器,按機(jī)組功率及安裝位置不同選擇不同的撓度的彈簧減震器,大功率設(shè)備可選用40MM撓度的彈簧減震器,較小功率空調(diào)主機(jī)可使用25MM常規(guī)彈簧減震器。同空調(diào)主機(jī),風(fēng)機(jī)水泵也應(yīng)用彈簧減震器做減振處理.并且適情況增加減震基座.除了對風(fēng)機(jī)、水泵等產(chǎn)生振動的設(shè)備設(shè)置彈性減振支座外，還應(yīng)在風(fēng)機(jī)與風(fēng)管之間采用軟管鏈接，風(fēng)管接頭宜采用人造材料或帆布材料制作。6號以下風(fēng)機(jī)，軟管的合理長度為200mm；8號以上的風(fēng)機(jī)，軟管合理長度為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、冷水機(jī)組、風(fēng)機(jī)盤管、空調(diào)機(jī)組等設(shè)備與水管之間用軟管連接，不使振動傳遞給管路。軟管有兩類：橡膠軟接管和不銹鋼波紋管。橡膠軟接管隔振減噪的效果很好，缺點(diǎn)是不能耐高溫和高壓，耐腐蝕性也差。在空調(diào)與采暖的水系統(tǒng)中多用橡膠接管。不銹鋼波紋管能耐高溫、高壓和耐腐蝕，但價格較貴，一般用于制冷劑管路的隔振。
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、穿墻處使用非燃軟性材料填充做減振處理。振動較大的設(shè)備吊裝時，采用吊式彈簧減震器。
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.選用高效、低噪聲水泵、風(fēng)機(jī)，并使水泵、風(fēng)機(jī)在最高效率點(diǎn)附近運(yùn)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.按噪聲標(biāo)準(zhǔn)控制風(fēng)管、風(fēng)口風(fēng)速，以滿足房間噪聲要求。
5. Control the wind speed of air duct and tuyere according to the noise standard to meet the room noise requirements.

6.空調(diào)機(jī)房內(nèi)壁表面貼附吸聲材料及吸聲孔板，機(jī)房門采用消聲密閉門，使墻體有吸聲能力，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
