This　paper　mainly　introduces　Air　Handling　Unit　control　in　the　Variable　Air　Volume　air　condition　system.　Combined　with　engineering　experiences,　it　introduces　some　experiences　of　supply　air　temperature　control　of　AHU,　and　makes　a　comparison　with　the　constant　static　pressure　control　strategy,　the　optimized　static　pressure　control　strategy,　and　the　total　air　volume　control　strategy,　to　give　some　recommendations　for　the　VAV　system　control.　©　2009　IEEE.
