F型自然冷却型，这种机型可通过空气/氟盘管（直接膨胀制冷）或空气/冷冻水盘管将室内空气冷却，水被室外干冷器冷却，（1）当室外温度高于ZET值时，水通过室内水/氟里昂板式换热器换热。（2）当室外温度低于ZET值时，水被室外空气冷却后通过水/空气盘管将室内空气冷却。

The F type free cooling model through the air/fluorine coil (direct expansion refrigeration) or air/frozen water coil is used for indoor cooling. Water was cooled by the outdoor dryer. (1) When the outdoor temperature is higher than the ZET values, water through the water/Freon heat exchanger changes the heat. (2) When the outdoor temperature is lower than the ZET values, water was cooled by outdoor air through water/air coil for indoor cooling.

This chart is for reference only, the new design of components and structures for the unit will change depending on the actual situation.

此工程图仅供参考，新机型所使用的元件及机组内部的设计会根据实际状况而有所变动。
