REVERSIBLE AIR-TO-WATER HEAT PUMPS 30RQS 039-160
Features and advantages
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).
Easy and fast installation
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)
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.
