（1）系统简洁、节省投资
机组具有防太阳暴晒、防锈蚀、防暴雨等性能，露天安装在屋顶，无需机房，节省宝贵的土地资源。整个空调系统无需设计、安装冷却塔和锅炉及相关管道，也无需冷却水泵和风机盘管等配套设备，节省了初投资。整个空调系统施工简单，安装快捷。
Simple system and capital saving
The unit has functions of anti-sun exposure, anticorrosion and anti-rainstorm. It can open-air installed on the roof without using the engine room, saving valuable lａnd resources. The whole central air-conditioning system does not require the design and installation of cooling tower, boiler or relevant pipelines, as well as the cooling water pump or fan coil, saving the initial investment. The construction and installation of the whole central air-conditioning system is easy and convenient.
（2）高效节能、功能扩展方便
采用全空气系统，换热盘管直接冷却/加热空气，没有中间传热媒体，避免了利用载冷剂换热所造成的能量损失，提高了机组运行效率。
机组可以配备多种功能段，可方便实现空气除湿、加湿、中效过滤，消声、杀菌以及全新风等功能。
Energy-efficient and convenient function expansion
It uses the full-air system and the heat exchange coil that is used for cooling/heating air directly without having to use intermediate heat transfer medium, avoiding the energy loss caused by refrigerating medium and enhancing the efficiency of unit operation.
The unit is equipped with a variety of functions, conveniently realizing air dehumidification and humidification, medium air filtration, noise elimination, sterilization, and all fresh air, etc.
（3）空气品质高、运行宁静
机组带有过滤、新风装置，可为大空间提供高品质的新鲜空气，机组运行平稳，整机噪声低。
High air quality and quiet operation
The unit has filter and fresh air device, providing high quality fresh air for large space. The whole unit has stable operation and low noise.
（4）安装灵活、维护方便
机组结构设计合理紧凑，占地面积小，安装灵活，运输方便，室外侧采用可开启式箱板结构，室内侧检修部位设有检修门，门上装有拉手型开关，机组日常观察和维护方便。
Flexible deployment and maintenance friendly
The structural design of the unit is reasonable and compact, covering a small area of land. It can be flexibly installed and be easily transported. Open-type plate structure is adopted outside, and the access door with a handle-type switch is designed inside. The daily observation and maintenance of the unit is convenient.
（5）优良的机组组件
机组选用高效半密闭式螺杆压缩机，可靠性高；高效内螺纹紫铜管/铝翅片换热盘管，保证机组从空气中充分高效地换取热量；采用大风量低噪音轴流式风扇和室内侧离心式风机；采用厂家的干燥过滤器、电子膨胀阀等系统配件，确保机组具有较高的性能水平。
Well-equipped assembly of the unit
The unit chooses the high efficiency semi-hermetic screw compressor which has a high reliability; high efficiency copper tubular with internal thread/aluminum finned exchanger ensures that the unit can be fully efficiency in exchange for heat from the air; it adopts the tube-axial fan that has large blowing rate and low noise, and the indoor centrifugal fan; by using branded system accessories such as dry filter and EEV, the high performance unit can be ensured.
