Air-to-Water Heat Pumps with Integrated Hydronic …

1 1 This new generation of Air-to-Water heat Pumps features the latest technological innovations, incorporating scroll compressors and operating on the ecological refrigerant HFC-407C. The 30RH heat Pumps from Carrier have an Integrated Hydronic module, with pump and expansion tank, limiting the installation to simple operations like connection of the power supply and the water supply and return auto-adaptive control system ensures intelligent control of the compressor start-up sequence. Featuresn refrigerant R-407C is a blend of R-32, R-125 and R-134a, ensures similar performances to those achieved with R-22 and offers an economical solution to environmental protec-tion problems. It has no effect on the ozone layer and can be used as a replacement for R-22 in air conditioning appli-cations with small and medium The components of these units are specifically designed for R-407C refrigerant , and all units have been submitted to the necessary laboratory tests to ensure perfect The unit incorporates two axial fans with horizontal air dis-charge.

2 The advanced design allows exceptionally low-noise Compact unit dimensions facilitate installation of these units in restricted Prepainted steel Removable panels for improved service and easier access to all The condenser coils are constructed of high-quality copper tube, expanded into pre-treated aluminium fins to offer high corrosion resistance in industrial and marine The refrigerant -to- water heat exchangers are plate heat exchangers, ensuring excellent heat transfer at reduced dimensions and low weight. The plates are made of welded stainless steel. This heat exchanger type requires only minimum refrigerant quantities, compared with traditional heat The scroll compressors run very quietly and vibration-free. They are known for their durability and reliability. The motor is fully cooled by suction gas and permits up to 12 starts per hour. The advanced concept of the scroll allows reverse rotation due to incorrect wiring, without impairing the operation of the compressors are especially designed for operation with The Hydronic module is factory-installed.

3 This eliminates the need to install the necessary components on site, making the unit more compact and easy to install. Carrier is participating in the Eurovent CertificationProgramme. Products are as listed in the EuroventDirectory of Certified Products. 30RH 017-033 Nominal cooling capacity kWNominal heating capacity kW Air-to-Water heat Pumps with Integrated Hydronic Module AQUASNAP 2 water fill system: - Spherical check valve- Pressure reduction valve- Safety valve Hydronic kit - Flow switch- Suction pressure gauge- Expansion tank- Spherical shutoff valve- Filter- Pressure pump- Spherical control valve- Discharge pressure gauge- Automatic purge. PRO-DIALOG Plus control PRO-DIALOG Plus is an advanced numeric control sys-tem that combines complex intelligence with great opera-ting simplicity. PRO-DIALOG Plus constantly monitors all machine parameters and safety devices, and precisely manages the operation of compressor and fans for optimum energy efficiency.

4 It also controls the operation of the water pump. A powerful control systemn The PID control algorithm with permanent compensation for the difference between entering and leaving water tem-perature anticipates load variations, and ensures intelligent leaving water temperature Reset of the leaving water temperature set point (according to the outdoor air temperature or the return water temperature).n PRO-DIALOG Plus 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 com-pressor short cycling. Clear and easy-to-use control systemn The operator interface is clear and user-friendly: LEDs and numeric displays ensure immediate verification of the unit operating A simple push of the button positioned on the synoptic heat pump diagram gives you immediate display of the usual parameters: temperatures, pressures, set point, compressor run times 10 menus offer direct access to all machine controls, including fault history, for rapid fault diagnosis.

5 Extended communications capabilitiesn PRO-DIALOG Plus offers a standard wired remote control with multiple functions for easy integration into any buil-ding management system: on/off control, cooling/heating mode selection, power demand limit or dual set point and a general alarm The optional CCN Clock Board offers enhanced control possibilities: Time scheduling of the unit with up to eight sequences, cascade operation of two units, remote control by communication bus through its RS 485 serial port, time scheduling for low-speed fan operation.
