has applied frontal induction and discharge method for the first time on a VRF unit, therefore keeping the building interior safe from strong winds associated with high rise buildings.

Sirocco fans designed to withstand high building wind speeds

Building wind and reverse wind effect are stronger at higher floor levels, which can cause discharge air to short cycle back to the induction side affecting system control. It can also cause damage to the fans, which in turn will considerably reduce system performance.

However, is designed to generate very strong airflow (7m/s or more) to

overcome this problem. This makes ideal for use in such high rise applications.

No interference from the discharge air between units or between floors

Because of the symmetrical design characteristics of conventional VRF systems, high rise installation is not always recommended (due to heat columns affecting system control on

higher floors). solves such installation problems using powerful left and right air discharge fans which throw the air outwards rather than upwards, allowing high rise installation with no control problems on the upper floors.
