For both the GSAC models (chillers alone), as well as for GSAH types (with additional heat-pump switchover function), there are now for both model groups 5 new systems for 230-V and 6 new systems for 400-V connection. The cooling capacity for the smallest unit is now 4.6 kW (until now: 5.5 kW), and the cooling capacity for the largest unit is now 14.6 kW (until now: 11.1 kW). The heating capacity covers a range of 5.7 kW (until now: 5.9 kW) to 16.8 kW (until now: 12.4 kW). In spring and autumn the heat pump of the GSAH models can effectively heat rooms climate-controlled by GEA acqua 2, since it functions at outside temperatures of -7 to 20°C.
Each of the new chiller groups is now available in one version for outdoor installation (for locations behind buildings or on the roof, for example) or as a version for installation inside buildings. As a result, a total of 44 different units are available: which means that GEA acqua 2 will effectively cover requirements for single-family homes, or for the climate control of shops or other small commercial facilities.
These new chillers adjust the fan speed as a function of condensation pressure. They also offer a speed-controlled water pump, as well as further features for energy-efficient and demand-driven operation. The chillers are also very quiet, so as not to disturb a quiet home.
Systems may be installed without a refrigeration certificate
The complete GEA acqua 2 system consists of chillers and quiet fan-coil units for installation in climate-controlled rooms. During winter the fan-coil units perform the heating function, and cool the room air in summer. Depending on demand, the fan-coil units use the heating circulation system of the normal central-heating system, or they take their useful energy from the chiller or from its heat pump.
Since the GEA acqua 2 uses water circulation systems to distribute its useful energy throughout a building, the system may also be installed by fitters who do not have refrigeration certification. As a result, heating-system installation staff can now enter the field of climate control with cooling features, since they are essentially installing a heating system that can also cool.
