We have recently completed the installation of a new Samsung DVM Plus IV VRF system within an office. The system comprised of 8 no. fan coil units and 2 no. Heat recovery units with DX coils. The system was a 3-pipe heat recovery system allowing for simultaneous heating and cooling.
The heat recovery units extract warm stale air from the offices and the heat used to temper the incoming fresh air. The units incorporate DX coils, which will automatically maintain the correct fresh air temperature.
All of the indoor units are controlled via a central touch screen controller which is very user friendly.
