Features and advantages
The AquaSnap Greenspeed heat pump systems can be used with a wide choice of Carrier terminal fan coil units - cassettes, low, medium and high-pressure satellite units, console units, underceiling units and high-wall units. Ecodesign is the European Directive that sets mandatory requirements for Energy related Products (ErP) to improve their energy efﬁciency. Carrier supports initiatives to reduce the environmental impact of its products. Air heat exchanger section - Vertical air heat exchanger coils - The latest-generation low-noise fans are now even quieter and do not generate intrusive low-frequency noise - Rigid fan installation for reduced start-up noise.
Easy and fast installation
Integrated hydronic module (option) - Fixed speed water pump or variable speed circulator - Water ﬁlter protecting the water pump against circulating debris - High-capacity membrane expansion tank ensures pressurisation of the water circuit (option) - Overpressure valve, set to 3 bar - Thermal insulation and frost protection down to -20°C, using an electric resistance heater and pump cycling. - Integrated water ﬁll system to ensure correct water pressure (option) No additional buffer tank required, simplyﬁng and speeding up the installation process (to be checked with the water volume of installation). Physical features - Advanced circuit design and component selection has resulted in a compact unit with an exceptionally small footprint that is easy to transport even through narrow doors. Reduced operating weight and a handle on the unit panels to facilitate transport. - The unit is enclosed by easily removable panels, covering all components (except air heat exchanger and fans). A neutral color (RAL 7035) to facilitate the intregration in residential area Simpliﬁed electrical connections - Main disconnect switch with high trip capacity (option) - 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.
Compressors - Low-noise INVERTER Twin rotary compressor with low vibration levels - Advanced technology providing maximum energyefﬁciency with high capacity available at peak conditions and optimised efﬁciency at low and mid compressor speeds. The AquaSnap Greenspeed heat pump DC inverter uses Intelligent Power Drive Unit (IPDU) hybrid inverter technology. An electronic management logic is used to optimised compressor opartion in all conditions, minimised temperature ﬂuctuation to give a perfect individual comfort control with signiﬁcant reduction of energy comsuption : • PWM: pulse width modulation of the direct current controls the compressor at partial load conditions, adjusting the frequency at ﬁxed voltage. The compressor speed is ﬁne-tuned and the system provides high-level comfort (no temperature ﬂuctuations) at exceptionally efﬁcient working conditions. Compressor frequency is increased continuously up to the maximum level. This ensures that there are no current draw peaks in the start-up phase. Inverter ramp-up speed makes soft starts unnecessary and ensures immediate maximum power. - The two rotary compression cylinders, offset from each other by 180°, and the DC brushless motor with the shaft in perfect balance ensure reduced vibration and noise, even at very low operating speeds. This results in an extremely wide range between minimum and maximum capacity with continuous operation, guaranteeing that the system is always optimised and provides maximum comfort at exceptionally high efﬁciency levels. - Twin-rotary cylinders, low vibrations and low load to the shaft ensure highest compressor reliability and a long trouble-free operating life. - All DC brushless twin-rotary compressors are equipped with internal system to secure the motor against oil issues due to colder climate. - A double compressor shield for acoustic insulation further reduces noise levels.
