1 Packaged Rooftop/Cooling Units 0036 Carrier is participating in the Eurovent Certification Programme. Products are as listed in the Eurovent Directory of Certified Products. 50 AZs Nominal cooling capacity kw The 50AZ packaged rooftop units are versatile and efficient air conditioners, designed for outdoor installation. The units are self-contained and can be installed in commercial and industrial applications. Features The new refrigerant R-407C, a blend of R-32, R-125 and R-134a, offers an economical solution to environmental proteciton problems. The components of these units are specifically designed for the new refrigerant, and the units have been submitted to necessary laboratory tests to ensure perfect operation. The unit cabinet is made of powder painted sheet metal, especially suitable for outdoor use. Reduced size and weight make these units ideal for today s lightweight building structures. Models 016, 024, 028 have scroll compressors; the other sizes have reciprocating hermetic compressors. All are designed for use with R-407C and include a thermal cutout to protect the motor against overloads and over temperatures. The compressors are mounted on vibration isolators. Crankcase heaters are standard for 034, 040. Double-inlet indoor fans have forwarded-curved blades. The revolutionary, low-niose, two-speed Flying Bird II fan is made of a composite recyclable material and employs a multi-blade design and rotating shroud, as used in the aeronautical industry. It is exceptionally quiet, and does not generate the low-frequency noise, irritating the human ear. At part load or low outdoor temperatures the fan automatically switches to the low speed. The heat exchangers are made of high-quality staggered copper tubing, mechanically bonded in precoated corrugated Aluminum fins, with a high level of corrosion ad UV protection. The refrigerant circuit uses deoxidized and dehydrated copper tubes with obus type access valves. It includes a full refrigerant charge, expansion valves, and all components required for correct unit operation.
2 The units are fully wired in accordance with EN standards and include thermo magnetic circuit breakers and a main disconnect switch. All pipes and refrigeration components are welded except for the compressors which are connected via rotolock connections. Pressure sensors are mounted directly on the pipes. Electrical connections are simplified, and the standard equipment includes a main disconnect switch and a single entry point of the three-phase without neutral power supply to the whole unit. PRO-DIALOG Plus Control PRO-DIALOG Plus is an advanced numeric control system that combines complex intellegence with great operating simplicity. PRO-DIALOG Plus constantly monitors all machine parameters, optimizing the operation of compressors and fans. A powerful control system The PRO-DIALOG Plus Control is auto-adaptive and guarantees total protection of the compressors. The system permanently checks the operating parameters and responds simultaneously to avoþd excessive cycling and maintain the ideal operating range for the compressor (temperatures and pressures out of range etc.). By taking corrective action before the fault occurs, the auto-adaptive control frequently prevents a shutdown of the cooling only due to a faulty condition. To optimize power consumption, PRO-DIALOG Plus automatically resets the space temperature setpoint in accordance with the outdoor air temperature or uses a second set-point (example occupied / unoccupied). Clear and easy-to-use control system The operator interface is clear and user-friendly: LED s and two numeric displays ensure immediate verification of all unit operating data. Buttons, conveniently positioned on a synoptic cooling only diagram, offer immediate display of the operating parameters: temperatures, pressures, set point, run times etc. 10 menus offer direct access to all machine controls, including a history of possible faults, for rapid and complete cooling only fault diagnosis. Extended communications capabilities PRO-DIALOG Plus allows remote control. Voltfree contacts regulate: start/stop, power demand limit or selection of the second set point. The system permits remote signaling of any possible anomaly for each refrigerant circuit. PRO-DIALOG Plus ensures the time schedule programming of the cooling only: - start/stop, -operation at the second set point (e.g.unoccupied mode), -low-speed fan operation (e.g. during the night) -This also controls the operation up to 6 units in a master/slave assembly and offers a serial RS 485 communication port.
