AIR-TO-WATER HEAT PUMPS 30RQ 017-040
Features and advantages
Easy and fast installation
■■ Increased energy efficiency at part load
-- Eurovent energy efficiency class A and B (in
accordance with EN14511-3:2013) in cooling and
heating mode. The exceptionally high energy efficiency
of the AquaSnap unit is the result of a long qualification
and optimisation process.
■■ Reduced maintenance costs
-- Maintenance-free scroll compressors
-- Fast diagnosis of possible incidents and their history
via the Pro-Dialog+ control
-- R410A refrigerant is easier to use than other
refrigerant blends
Environmentally balanced
■■ Non-ozone depleting R410A refrigerant
-- Chlorine-free refrigerant of the HFC group with zero
ozone depletion potential
-- Very efficient - gives an increased energy efficiency
ratio (EER)
■■ Leak-tight refrigerant circuit
-- Brazed refrigerant connections for increased leak-
tightness
-- Verification of pressure transducers and temperature
sensors without transferring refrigerant charge
Superior reliability
■■ State-of-the-art concept
-- Cooperation with specialist laboratories and use of
limit simulation tools (finite element calculations) for
the design of the critical components, e.g. motor
supports, suction/discharge piping etc.
■■ Auto-adaptive control
-- Control a lgorithm prevents excessive compressor
cycling and permits reduction of the water quantity in
the hydronic circuit (Carrier patent)
■■ Exceptional endurance tests
-- Corrosion resistance tests in salt mist in the laboratory
-- Accelerated ageing test on components that are
submitted to continuous operation: compressor
piping, fan supports
-- Transport simulation test in the laboratory on a
vibrating table.
CONTROLS
■■ Integrated hydronic module
-- High-pressure centrifugal water pump
-- Water filter protecting the water pump against
circulating debris
-- High-capacity membrane expansion tank ensures
pressurisation of the water circuit
-- Overpressure valve, set to 4 bar
-- Pressure gauge to measure the system pressure.
-- Automatic purge valve positioned at the highest point
of the hydronic module to remove air from the system.
-- Thermal insulation and frost protection down to
-10°C, using an electric resistance heater and pump
cycling.
-- Integrated water fill system to ensure correct water
pressure (option)
■■ Physical features
-- With its small footprint the unit blends in with any
architectural styles.
-- The unit is enclosed by easily removable panels,
covering all components (except air heat exchanger
and fans).
■■ Simplified electrical connections
-- A single power supply point (power supply without
neutral available as an option and in standard for units
size 40kW)
-- 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.
Economical operation
HEATING
■■ Compressors
-- Low-noise scroll compressors with low vibration levels
-- The compressor assembly is supported by anti-
vibration mountings
■■ 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.
