Features and advantages
Low sound level
Coil section with ﬁxed speed fans (30RQM models): - Coils in V-shape with an open angle, allowing quieter air ﬂow across the coil - Low-noise 4th generation Flying Bird fans, made of a composite material (Carrier patent) - Rigid fan installation for reduced noise (Carrier patent). Coil section with Greenspeed® variable-speed fans (30RQP models recommended by Carrier for even quieter operation): - Exceptional acoustic signature during part-load operation through smooth fan speed variation. Speciﬁc control functions or features to reduce noise level during night or unoccupied periods: - Night time sound control with capacity and fan speed limitation - Low-noise scroll compressors with low vibration level - The compressor assembly is installed on an independent chassis and supported by ﬂexible anti-vibration mountings. - Dynamic suction and discharge piping support, minimising vibration transmission (Carrier patent) - Acoustic compressor enclosure, reducing radiated noise emissions (option). Integrated hydronic module with Greenspeed® variable-speed pump (option recommended by Carrier) - Easy and fast electronic setting of the nominal water ﬂow at unit commissioning thus eliminating the water ﬂow control valve adjustment - Automatic control of the pump speed based on constant speed, constant pressure difference or constant temperature difference. Simpliﬁed electrical connections - A single power supply point without neutral - Main disconnect switch with high trip capacity - 24 V control circuit without risk from a transformer included. Fast unit commissioning - Systematic factory test before shipment - Quick-test function for step-by-step veriﬁcation of the instruments, electrical components and motor.
Reduced installation costs
Optional Greenspeed® variable-speed pump with hydronic module (option recommended by Carrier) - Elimination of the water ﬂow control valve cost - Water system design with variable primary ﬂow (VPF) can provide signiﬁcant installation cost savings compared with traditional constant primary-variable secondary systems; elimination of the secondary distribution pump, etc. - Water system design with fan coils ﬁtted with 2-way valves instead of 3-way valves.
Non-ozone depleting R410A refrigerant Reduced direct warming potential (10% of total equivalent warming impact): - Low R410-A refrigerant charge - Leak-tight refrigerant circuit with minimum brazed refrigerant connections - Qualiﬁed Carrier service people for refrigerant servicing - ISO 14001 manufacturing site. Reduced indirect warming potential (90% of total equivalent warming impact): - Reduced unit energy use (high full- and part-load efﬁciency) - Pumping energy use can be reduced up to 2/3 using Greenspeed® variable-speed pump.
Fast and easy installation
Compact design - The AquaSnap units are designed to offer compact dimensions and low weight for easy installation. Integrated hydronic module (option) - Low or high-pressure water pump (as required) - Single or dual pump (as required) with operating time balancing and automatic changeover to the back-up pump if a fault develops - Water ﬁlter protecting the water pump against circulating debris - Pressure transducers for direct numerical display of the water ﬂow rate and water pressures - Thermal insulation and frost protection down to -20 °C, using an electric resistance heater (option) - High-capacity membrane expansion tank (option).
