Vaha is designed for the Mediterranean and coastal Aegean climate, where winters are mild and summers long and hot. In these regions the temperature rarely drops below zero in winter, while in summer the cooling load exceeds the heating load. Its design point is A +2 / W 55: at +2 °C outdoor air it delivers its rated capacity and produces 55 °C water.
Tuned for cooling
Because it will be cooling for most of the year, the series is tuned for cooling efficiency as much as for heating. The R32 cycle keeps its cooling efficiency even when it gets very hot outside. The compressor is DC inverter and the fan BLDC.
One outdoor unit, several indoor units
Up to three indoor units can be connected to one outdoor unit. In holiday homes and small tourist facilities, each unit of the building has its own indoor unit while a single outdoor unit serves them all. The indoor unit can be the wall-hung HİD / HİT, HİDRA with its tank or HİDREM with direct-expansion cooling. Underfloor heating, radiator and fan coil circuits are supplied from a shared system; domestic hot water comes from the indoor unit's tank or from an external cylinder. Remote monitoring and solar energy integration can be added.
Selection
Homes, holiday homes, tourist facilities and cooling-dominated offices on the Mediterranean and Aegean coasts are the typical projects for this series. For a project in Marmara that also has to get through the winter without trouble, the Poyraz series is the better fit. There are three capacities: 12, 14 and 16 kW. The model is determined by the heat loss calculation, which follows from the insulation, the orientation of the façades and how the building is used.
