Features and advantages Features Easy and fast installation The main features of this product range are: ■■ Integrated hydronic module (option) -- Multi-speed centrifugal water pump, based on the pressure loss of the hydronic installation. -- Water filter protects the water pump against circulating debris. -- Pump protected against cavitation by a pressure transducer that measures the entering water pressure. -- Overpressure valve, set to 4 bar. -- Thermal insulation and frost protection down to -20°C, using an electric resistance heater (see table of options). ■■ Physical features -- The unit has a small footprint and a low height (1329 mm) allowing it to blend in with any architectural styles. -- The unit is enclosed by easily removable panels, covering all components (except condensers and fans). ■■ Simplified electrical connections -- Single power supply point without neutral. -- Main disconnect switch with high trip capacity. -- Transformer for safe 24 V control circuit supply included. ■■ Fast commissioning -- Systematic factory operation test before shipment. -- Quick-test function for step-by-step verification of the instruments, electrical components and motors. ■■ Energy savings The 61AF range is certified to the Eurovent energy efficiency class A with a coefficient of performance (COP) of over 4. This complies with the COP required by the Ecolabel certification. ■■ Ease-of-installation The high-temperature AquaSnap heat pumps incorporate an optional hydronic module with a multi-speed pump. ■■ Easy integration The low noise levels of the 61AF heat pump and its very compact chassis reduce the noise disturbance from the unit. ■■ Application flexibility The operating range allows outside temperatures down to -20°C and leaving water temperatures up to 65°C for domestic hot water applications. -- Intelligent unit control permits unit operation in extreme conditions, minimising unit shut-down times. -- Hot water production at 65°C is available continuously. HEATING Carrier quality is your guarantee for the safety and durability of the installation. The AquaSnap high-temperature heat pumps incorporate the latest technological features: -- scroll compressors with vapour injection -- low-noise fans made of a composite material -- auto-adaptative microprocessor control -- electronic expansion valve -- multi-speed pump. The AquaSnap high-temperature heat pumps can be equipped with a hydronic module that is integrated into the heat pump chassis, limiting the installation to straight-forward operations like the wiring and the connection of the hot water supply and return piping. Quiet operation ■■ Compressors -- Low-noise scroll compressors with low vibration level. -- The compressor assembly is installed on an independent chassis and supported by anti-vibration mountings. -- Dynamic suction and discharge piping supports, minimising vibration transmission (Carrier patent). ■■ Evaporator section -- Vertical evaporator coils -- Protection grilles on anti-vibration mountings to protect the heat exchanger against possible shocks. -- Latest-generation low-noise Flying Bird fans, made of a composite material (Carrier patent), are now even quieter and do not generate intrusive low-frequency noise. -- Rigid fan installation for reduced start-up noise (Carrier patent). 414 Economical operation ■■ Increased energy efficiency -- Eurovent energy efficiency class A (in accordance with EN14511-3:2011). -- The exceptional energy efficiency level (COP) of the high-temperature AquaSnap heat pumps in the heating mode is the result of a long qualification and optimisation process. -- The electronic expansion device (EXV) allows operation at a lower condensing pressure (COP optimisation). -- Dynamic superheat management for better utilisation of the condenser surface. ■■ Reduced maintenance costs -- Maintenance-free scroll compressors with vapour injection. -- Pro-Dialog+ control offers fast diagnosis of possible incidents and their history. Environmentally balanced ■■ Non ozone depleting R-407C refrigerant -- Chlorine-free refrigerant of the HFC group with zero ozone depletion potential. -- Very efficient - ensures an increased energy efficiency ratio (COP). ■■ Leak-tight refrigerant circuit -- Brazed refrigerant connections for increased ­leaktightness. -- Reduction of leaks due to elimination of capillary tubes (TXVs). -- Verification of pressure transducers and temperature sensors without transferring refrigerant charge.
