Generally speaking , studies concerning about the energy , saving for hvac systems are carried out passively or initiatively , this paper intend to discuss the impacts produced by different hvac indoor air temperature control strategies , humidity control strategies and outdoor air control strategies in different hvac systems in terms of energy consumption and indoor environment parameters 一般而言,研究空調系統的節能主要是從兩個方面進行:被動方面和主動方面。本文是從后者出發探討空調系統中的室內溫度、濕度和新風控制策略對空調系統運行能耗的影響,同時也涉及到不同的控制策略對室內環境參數的影響分析。

This paper analyzes the impacts in energy consumption and indoor environment parameters by different hvac indoor air temperature control strategies , humidity control strategies and outdoor air control strategies equipped with in hvac systems , and presents some means and measures to achieve energy saving and obtain disable indoor air environment in terms of these control strategies and operating management 本文對所確立的研究對象從空調系統的室內溫度、濕度和新風控制策略出發多方位、多角度地研究了它們對空調系統運行能耗和室內環境參數的影響,并從控制策略和設計、運行管理上提出了實現空調系統節能運行同時兼顧室內環境參數的辦法和措施。

The mssr mode s technology , which was introduced firstly for the purpose of air tranfic control ( atc ) system , is based on the individually addressing and selective interrogation technology . the mode s can overcome many problems exist in mode a / c , such as signal interference , limited aircraft identification , garble and fruit , and provides the ability to build digital data link . many countries and organizations do them best to support researches about the communication , navigation and surveillance technology , which are all based on the mode s , and many productions have been adopted step by step by the international civil aviation organization ( icao ) . so , to research the key technologies of mode s will contribute a lot to the development of domestic aviation system , especially for the air control system , identification friend foe and navigation system 它建立在獨立編址、選擇性詢問的基礎之上,能夠解決在模式a / c中存在的信號干擾、有限的信息編碼、幻影( garble )和異步應答( fruit )等問題,同時在數據鏈路方面有著巨大的潛力。國際上,模式s的數據鏈技術得到了廣泛的關注,許多國家和組織大力支持基于模式s的通信、導航和監視技術以及航空管理新技術的研究,許多成果正逐步被國際民用航空組織( icao )所采用。因此,對模式s核心技術的深入研究對于我國在航空管理、敵我識別、導航等方面的發展有著重大的意義。

* the huge american market results from huge military helicopter demand , oil crisis in 1970s , government policy and etc . but chinese market is confined by comparatively lower gdp , weak military demand , preliminary air control and powerless industry association . * facing the keen competition , catic should further strengthen its competitive advantage in helicopter sales ability , extend its business line to supply service for helicopters such as fixed base operation *面對日益激烈的競爭環境,中航技公司應該大力增強其在銷售領域的競爭優勢,圍繞航空產品和技術進出口這一核心業務向外圍擴展,進入直升機運營領域開展直升機服務業務及運營通用航空服務站,在新產品的研發方面則應以起飛重量不超過4噸的單發渦軸直升機為主,采用合資合作等方式。
