VRF Condenser Design and Installation in Various Situation
For air conditioning system designers, it is always difficult to find space to install outdoor units without sacrificing performance. Outdoor unit installation in severe conditions tends to cause discharged air short circuits. As a result, wasting energy and shortening machine life. For VRF outdoor unit systems to operate properly, it to ensure proper fresh air supply and exhaust of discharged air. This guide shows optimum layouts for outdoor units in various situations.
Air Short Circuit
It refers to a phenomenon when discharged air (exhaust heat) from the condenser is drawn back into the suction vent.
If air short circuit occurs:
- Efficiency of cooling operations will decrease.
- Shortage in capacity.
- High pressure cut-off will occur (operation stops).
- The lifespan of the outdoor unit will be shortened.
VRF Condenser Design and Installation In Case of Severe Condition
After making one part of the wall into a louvre, place the exhaust vent in a position higher than the wall. And make sure that intake air and exhaust air do not mix.
