HEATING
Features and advantages
Features
The main features of this product range are :
■■
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 a hydronic module with a variable speed pump , in option .
■■
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 .
■■
Availability --
Intelligent unit control permits unit operation in extreme conditions , minimising unit shut-down times .
--
Hot water production at 65 ° C is available continuously .
Carrier quality is your guarantee for the safety and durability of the installation .
The high-temperature heat pump range incorporates 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 high-temperature AquaSnap heat pumps can be equipped with a hydronic module that is integrated into the heat pump chassis , limiting the installation to straightforward 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 are now even quieter and do not generate intrusive lowfrequency noise .
-- Rigid fan installation for reduced start-up noise .
Easy and fast installation
■■
Integrated hydronic module ( option ) --
Variable speed water pump , based on the pressure loss of the hydronic installation .
--
Water filter protects the water pump against circulating debris ( option ).
--
Overpressure valve , set to 3 bar for the 61AF 014 and to 4 bar for the 61AF 019 .
--
Thermal insulation and frost protection down to -20 ° C , using an electric resistance heater .
■■
Physical features --
The unit has a small footprint and a low height ( 1103 mm for the 61AF 014 and 1550 mm for the 61AF 019 ), 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 with neutral .
--
Main disconnect switch with high trip capacity ( standard only for 61AF 019 ).
--
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
■■
Increased energy efficiency --
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 .
