REVERSIBLE AIR-TO-WATER HEAT PUMPS 30RQS 039-160
Features and advantages
Quiet operation
Hydronic module
Easy and fast installation
■■ Physical features
-- The unit has a small footprint and a low height (1330
mm) allowing it to blend in with any architectural
styles.
-- The unit is enclosed by easily removable panels,
covering all components (except air heat exchangers
and fans).
■■ Simplified electrical connections
-- A single power supply point without neutral
-- Main disconnect switch (option 70) 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.
CONTROLS
AIR TREATMENT
■■ Integrated hydronic module (option)
-- Centrifugal low or high-pressure water pump (as
required), based on the pressure loss of the hydronic
installation
-- Single or dual water pump (as required) with operating
time balancing and automatic changeover to the backup pump if a fault develops
-- Water filter protects the pump against circulating
debris
-- Pressure measurement, using two pressure
transducers and allowing indication of water flow rate,
water pressure and lack of water.
-- High-capacity membrane expansion tank ensures
pressurisation of the water circuit
-- Overpressure valve, set to 4 bar
-- Speed variator on the pumps (option) to ensure the
correct flow rate, based on the system requirements
-- Thermal insulation and frost protection down to
-20°C, using an electric resistance heater (see table of
options)
HEATING
■■ 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 support,
minimising vibration transmission (Carrier patent).
■■ Air evaporator/condenser (30RQ) section
-- Vertical condenser coils
-- Low-noise latest-generation Flying Bird IV 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).
