Anleitung Zusammenfassung
They may be located in any area having unobstructed air circulation; the low silhouette permits installation in varied ground or roof locations. Each unit consists of a direct drive motor (or motors), fan (or fans), fan guards, motor mounts, condenser coil with integral subcooling circuit, wind deflector, and electrical junction box. Weather Armor* enclosures (which are also provided for 09DC016) have a baked enamel finish which provides maximum weather protection. Capacities 15 Tons and Over 09DC Air-Cooled Condensers are available in 15-, 20-, 25-, 30- and 40-ton sizes. The 25-, 30- and 40-ton sizes are designed for use in multiples to give capacities of 50, 60 and 80 tons. Each size has three direct drive fans, three motors and motor mounts, three guards, a junction box, and a condenser coil with integral subcooling circuit. The 20-, 25-, 30- and 40-ton units, all using vertical air flow, may have 2 or 3 circuits, each with an integral subcooling circuit. Each circuit may be used as a separate condenser for a single system. Double-weight, hot dipped, galvanized steel enclosures give maximum protection. FEATURES • Multiple Fans and Motors provide inexpensive, reliable system control in intermediate seasons. Standby protection is provided in case one fan motor fails. • Subcooling permits greater liquid lift in vertical risers without liquid flashing. Special coil circuiting cools liquid refrigerant below the saturated condensing temperature, extending system capacity without increasing motor horsepower. • Direct Drive Fans require no tensioning device or pulleys. Alignment problems, belt maintenance, and friction loss are eliminated. • Three Types of Head Pressure Control (Accessory) are available to maintain a refrigeration load by hold- ing a minimum head pressure and reducing condenser capacity at low outdoor temperatures. 1. Motormaster Electronic Control (9AB6, 8, 12 and 09DC016, single-phase) modulates condenser fan motor speed from zero to full rpm. 2. Fan Cycling Control cycles one fan (9AB8, 12) or two fans (09DC) for control during intermediate seasons. 3. Head Pressure Control Damper (09DC024, 084), mounted below unit at the uncontrolled fan section, further reduces capacity. • Winter Start Control — Optional package permits start-up of compressor regardless of low temperatures. © Carrier Corporation 1966 SINGLE FEATURE SHEET AVAILABLE Form 9AB, 09DC-2P PHYSICAL DATA UNIT 9 AB 0 9 D С 09DC054 (T WO 028’s) 09DC064 (Two 034’s) 09DC084 (Two 044’s) 6 8 12 016 024 028 034 044 RATING (tons)* 6.8 10.5 13.8 15.8 22.1 28.0 35.8 46.7 56.0 71.7 93.4 NET WEIGHT (lb)t 215 315 410 550 854 904 1225 1600 1808 2450 3200 FAN (Prop.), No. Prop.
