CONDENSER: One condenser shall be provided for each compressor. The condensers shall be shell-and-tube design with removable heads and mechanically cleanable tubes. Condenser tubes shall be nominal inch. O.D. copper. Condenser waterside working pressure shall be 400 psig. Unit will allow condenser water piping to be brought to the condensers from the right side of the unit. All water piping including economizer valve package shall be manifolded into a single inlet and outlet and extended to the exterior of the unit. EVAPORATOR: The evaporator coil shall be seamless copper tubes expanded into aluminum fins. Tubes shall be -inch O.D. with internally enhanced surfaces. The coil shall have a staggered tube arrangement with interlaced circuiting and no more than 12 fins per inch. The drain pan shall be fabricated of stainless steel and be insulated with -inch of one pound density fiberglass. Drain piping shall be provided to the exterior of the unit. REFRIGERANT CIRCUIT: Shall be independent and completely piped including filter driers, sight glasses, distributors, expansion valves with adjustable superheat and external equalizer, and high pressure relief valves with a -inch SAE flare connection. The circuits shall be tested, dehydrated and then charged with oil and Refrigerant-22. SUPPLY FAN, DRIVE AND MOTOR: The supply fan shall be dual, forward curved medium pressure fans secured to a solid steel shaft with grease-lubricated bearings designed for 200,000 hours. The drive components shall include fixed-pitch sheaves and multiple V-belts sized for 150 percent of nominal motor horsepower. The supply fan motor shall be high efficiency open drip-proof. The supply fan motor shall have a standard T-frame. The entire fan assembly, including drive components, shall be mounted on a common base. The fan base shall be isolated inside the unit. The entire assembly shall be statically and dynamically balanced at the factory to a maximum tolerance of 3 mils peak to peak. FAN MODULATION: The variable volume unit shall operate at design airflow based on fan and motor drive selections. Fan and motor sheaves will be selected for a rpm to develop airflow at design static pressure. INLET GUIDE VANES: Airflow modulation shall be by inlet guide vanes. The inlet vanes, complete with electric actuator, linkage and controller shall be factory-installed and adjusted. The static pressure setpoint shall be adjustable. A duct static pressure sensing probe shall be provided for field-installation. FILTERS: Two-inch medium velocity throwaway filters shall be provided for unit operation. UNIT CONTROLS: Unit Control Module -- The microprocessor controller shall control all unit functions, including the economizer, mechanical refrigeration and fan modulation and monitor diagnostics. All controls shall be factory installed and adjusted. The controller shall include a switch to place the unit in Auto Remote, Auto Local or Stop/Reset mode; an indicator display to show unit operating status, diagnostics and setpoints; and adjustable setpoints for supply air temperature, supply air pressure, economizer minimum position, supply air temperature control band and supply air pressure high static limit. The three-position switch and indicator display shall be accessible without opening any unit panels. ENTERING AIR TEMPERATURE PROTECTION: A single-point sensor is used to detect entering air temperature to the unit. If entering air temperature to the unit exceeds 135 F or falls below 37 F, the unit will shut down and dispay a diagnostic code. Manual reset is required when the entering airtemperature rises above 135 F. RATINGS: Design cooling capacity shall be 30 tons nominal based on standard ARI conditions. Designs airflow shall be 11,000 CFM @ 0.65" E.S.P. Power supply shall be 208 volts, 60 Hertz, 3 phase.
