Here a number of factors must be taken into consideration, such as the environmental standard of the area where the engine room is located, the fender structure of the engine room as well as the engine type, power level and the cooling air volume, etc. the core of the overall control is the concept of " equal sound insulation ", which means to apply a closed fender structure to isolate the engine unit from outside parts so as to cut the outward sound radiation
經過多年來與環保部門的合作，對油機房進行消噪聲處理，積累了一些治理經驗，主要是必須根據具體的機房項目來確定相應的控制方案，這其中應考慮機房所在區域的環境標準，機房圍護結構形式及油機機型、功率、冷卻風量等因素。綜合控制的核心是等隔聲概念，即用一封閉的圍護結構將機組與外界隔離開來，減少聲源對外的聲輻射。 -

The experiment ' s results show that the system is stable under the static pressure control and energy saving under the minimum total supply air volume control. although the terminal dampers ' s tuning time is prolonged under the minimum total supply air volume control, it can be reduced by adopting the appropriate sampling time when debugging the system. from all of this we can conclude thart the minimum total supply air volume control has a good application perspective
實驗結果表明，定靜壓控制方式下系統較為穩定，最小總送風量控制比定靜壓更加節能，但它延長了末端閥位的調節時間，在系統調試時，我們可通過選擇合適的采樣時間來縮短閥門的調節過程，所以最小總送風量控制具有廣闊的應用前景。 -
At present, variable air volume ( vav ) air - conditioning system is the main steam of the whole air conditioning system in china and abroad because of its large energy conservatioa however, since vav system is multivariable, strongly coupled, nonlinear and time variant, its design, performance and management are more difficult than constant air volume ( cav ) system, and stable control of the entire vav system is focused in particular in china study on the stability, the key condition of the vav operation, the paper divide the vav system into ahu part and terminal part based on the coordination control strategy
目前，變風量（ variableairvolume ， vav ）空調系統以其巨大的節能潛力逐漸成為國內外空調系統的主流。但是，變風量（ vav ）空調系統具有多變量、強耦合、非線性、時變的特點，因此它的設計、運行和管理都比定風量（ constantairvolume ， cav ）系統難度大。這也是限制vav系統更廣泛應用的一個重要原因。 -
