多联机定义 ,[object Object],[object Object]
多联机定义 按外机配置的压缩机种类分 定频多联机、变频多联机、变频加定频多联机,变容多联机 ( 本片特指定频多联机 ) 按内机配置数量分类 一拖二、一拖三、一拖四 ……等等、内机数量不固定的变频自由拖 ARV 、变容自由拖等
一拖二多联机的工作原理
多联机的适用场所 多联机与低静压风管机一样,广泛应用于小型超市、宾馆、酒楼、餐厅、办公室、会议室等 多联机特别适合多房间小面积、有一定层高吊顶装修的中高档场合,如对外机数量有限制的场所尤其适合,如宾馆、娱乐包厢、别墅等,可作为现代家庭空调(分体机、柜机等)的换代产品
二、产品介绍 1 、型号命名规则 2 、产品型谱 3 、机组结构介绍 4 、奥克斯多联机的优点 5 、功能介绍 6 、产品技术参数表
多联机与其他机型的优缺点 1 、费用较家用机高 2 、维修维护比家用机复杂 3 、对层高有一定要求 1 、风口与室内装修协调,档次高 2 、室内气流好,整个房间内温差小 3 、可引入新风避免空调病; 4 、吊顶安装不占室内空间 5 、冷凝水可做到有组织排水。 6 、 在相同数量的室内机情况下,室外机 所占用的空间大大减少。 家用空调 1 、控制器出现故障时影响全部室内机使用 。 1 、只用一个室外机。设计配置灵活,安装方便美观 2 、设备及工程费用低,能减小运行费用。  3 、控制灵活方便,可单台多台内机运行。可实现网络控制集中管理。 4 、长配管、高落差安装随意、方便 风管机组 1 、室外机数量多,有时不好摆放 2 、档次相对低点 3 、铜管长度限制 1 、安装工程简单,安装成本低,比起水系统低 30% 左右 2 、维护简单,冬季室外温度低于 0℃ 的地区不需要考虑系统的防冻 3 、各个房间基本上可实现独立控制,冷热随心。 4 、运行、维护成本低。 户用水机 模块机等水系统 多联机缺点 多联机优点
