This atypical installa­tion – the units are situated under the sunbathing terrace – required a CFD analysis to consider the installa­tion possibi­lities. All outdoor units are equipped with central air deflectors to conduct the exhaust air away from the installa­tion site. All indoor hydromo­dules are hydrauli­cally connected to one system leading to an accumula­tion tank, from which the water is used for floor heating, AHU exchanger­s, pool exchangers and HDW exchanger­s.

The VRF V-II system secures the air-conditi­oning of the offices, shops, restauran­ts and cafés. The users control the system by wired remote controller­s. The central management is secured by SYSTEM CONTROL­LER software which monitors the system and collects data for electri­city charge apporti­onment.

Unique installa­tion of FUJITSU technolo­gy in Hotel Horal. All units provide cooling and heating of the whole hotel complex. The heat pumps are used for HDW in the hotel rooms, the main building with conferen­ce halls and kitchen. Industri­al exchanger with FUJITSU outdoor unit and control module ATW-C maintain constant tempera­ture of +12°C in the liquor storage ro­om.

Special installa­tion of outdoor units connected by means of VRF-Kits to AHU unit with five-circuit air exchanger. Total capacity of 200 kW to secure the required tempera­ture in the producti­on hall. Controlling is ensured by BMS with cascade control.

The VRF V-II system A consis­ts of one outdoor unit connected to AHU unit by means of VRF-Kit. It is used for cooling and heating the hotel kitchen and the restauran­t. Five standard units are also connected to the system, cooling the 2nd restauran­t. The VRF V-II system B is used for cooling the conferen­ce halls. All indoor units are connected to the central controlling system by means of ACC modules. The split type units are used in two hotel server rooms, hotel bar and spa centre. .

All indoor units are installed in the ceiling cavity without visible vents. The air is blown into the ceiling cavity and passes through the grid ceiling to the offices be­low.

The VRF systems are connected and monitored by BMS using BACnet gateway. The split type units used in server rooms are controlled by BMS by means of ACC modules.

An extensive installa­tion in two separate buildin­gs. The units are used to cool the offices of a renowned health insurance company. All VRF systems are monitored and controlled by SYSTEM CONTROL­LER software. The split type units are also connected to the software by means of VGGX convertor­s. SYSTEM CONTROL­LER also manages the energy saving operati­on – controls the set modes and tempera­tures, automati­cally switches off the units in the evening.

The VRF V and V-II systems are the only source of heating in the entire hotel complex. The heat distribu­tion is ensured by indoor units with special VRF-KITs. The remaining capacity of the system is used to heat the pool water and the HDW tank.
