High-Efficiency Air-To-Water Heat Pumps Carrier is participating in the Eurovent Certification Programme. Products are as listed in the Eurovent Directory of Certified Products. AQUASNAP JUNIOR 3RHV 6-11 Fan coil application Nominal cooling capacity 4.4-8.5 kw Nominal heating capacity 6.-.2 kw Floor heating application Nominal cooling capacity 6.1-11.8 kw Nominal heating capacity 6.2-.9 kw These heat pumps have been designed for space heating and cooling and are suitable for both fan coil and floor heating applications. 3RHV heat pumps feature the latest technological innovations, incorporating scroll compressors and operating on the ozone-friendly refrigerant HFC-4A. An electronic, microprocessor-based auto-adaptive control system ensures intelligent control of the compressor start-up sequence, permitting operation at low system water volumes. Features Refrigerant R-4A is a blend of R-32 and R-125, ensures superior performances to those achieved with R-47C and offers an economical solution to environmental protection problems. It has no effect on the ozone layer. The components of these units are specifically designed for R-4A refrigerant, and all units have been submitted to the necessary laboratory tests to ensure perfect operation. The unit incorporates one or two two-speed axial fans with horizontal air discharge. The advanced design allows exceptionally low-noise operation. At part load conditions or at low outdoor temperatures the fan speed is automatically reduced by 5%, for even quieter operation. The control system also permits programming operation at reduced speed for a preset time period. 3RHV sizes 8 and 11 are equipped with a soft starter device to limit the starting current. The Pro-Dialog Junior operator interface integrated into the front panel permits easy user control of the main unit functions: start/stop, temperature selection, alarm code display. The compact dimensions and reduced weight of these units facilitate installation, even in very restricted spaces. The use of galvanised steel panels guarantees increased resistance to atmospheric conditions. These components have exceeded the stringent salt-spray corrosion resistance tests according to ASTM 117, with over 5 hours exposure to aggressive environments. The panels are removable for improved service and easier access to the internal components. The condenser coils are made of copper tubes, mechanically expanded into aluminium fins, with an increased heat exchange surface. The refrigerant-to-water heat exchangers are plate heat exchangers, ensuring optimum heat transfer at reduced dimensions. The plates are made of welded stainless steel. This heat exchanger type requires less refrigerant than traditional heat exchangers of the same capacity.
Scroll compressors run very quietly and vibration-free. They are known for their durability and reliability. The motors are fully cooled by suction gas and permit up to 12 starts per hour. These compressors are especially designed for operation with R-4A. Microprocessor-controlled automatic outdoor heat exchanger defrost cycles allow the unit to operate with high efficiency at low outdoor temperatures. PRO-DIALOG control system PRO-DIALOG is an advanced numeric control system that combines complex intelligence with great operating simplicity. PRO-DIALOG constantly monitors all machine parameters and safety devices, and precisely manages the operation of compressor and fans for optimum energy efficiency. It also controls the operation of the external water pump. A powerful control system The PID control algorithm with permanent compensation for the difference between entering and leaving water temperature anticipates load variations, and ensures intelligent leaving water temperature control. Dual set point: two different supply water temperature set points can be manually programmed or selected, according to the thermal load expected during the course of the day in the zones to be air conditioned. This always ensures maximum comfort at minimum energy consumption. PRO-DIALOG control is auto-adaptive for improved heat pump protection. Compressor cycling is automatically adapted to the characteristics of the application according to the inertia of the water loop and prevents dangerous compressor short cycling. Note: The hydronic module is not provided: the expansion tank, safety valve and water pump must be installed on site.
