About this file
This is a technical specification document for a rooftop-mounted HVAC unit for the West Virginia Air National Guard (WV ANG) Coonskin Armory Drill Hall RTU replacement project. The specification details an AAON model RN-018-C-A-8 rooftop unit designed to provide cooling and heating for the drill hall facility. The unit is configured as an 18-ton air-cooled packaged system with a cooling capacity of 206 megabytes per hour (MBH) and natural gas heating capacity of 270 MBH with four-stage staging for both cooling and heating. The RTU features a single 7.5-horsepower supply fan delivering 7,000 cubic feet per minute (CFM) of airflow, an evaporator coil with standard 4-row configuration, R-454B refrigerant charge of 229 ounces, and MERV 8 filters in a 25x20x2-inch cartridge format with six units. The unit is equipped with an economizer for outside air control, DDC (direct digital controls) with isolation relays, a clogged filter switch, and remote safety shutdown capabilities.
The RTU specifications include detailed performance ratings indicating cooling efficiency rating (EER) of 12.05 BTU/hW at AHRI standard conditions and application EER of 9.2 BTU/hW, with a total system static pressure of 3.17 inches water gauge and maximum duct static pressure of 3.52 inches when airway is blocked. The unit is specified for 208 volts, 3-phase, 60-hertz power with total full-load amperage of 85 amps and minimum circuit amperage of 91 amps. The cabinet is galvanized double-wall construction with R-16 foam insulation and premium AAON gray paint finish. The unit measures 138 inches wide by 64 inches long by 60 inches high with an approximate operating weight of 3,229 pounds. The document includes comprehensive acoustic data, electrical specifications, control terminal descriptions, dimensional drawings showing clearance requirements and gas heat exchanger access details, and roof live load rating certification indicating the unit can support maximum concentrated loads of 200 pounds and uniform loads of 35 pounds per square foot.

Reference: Equipment Roof Live Load Rating Certification Statement Rooftop Mounted Mechanical Equipment
AAON A/C Unitary Large Package Unit (11 to 30 Tons) Model No.: RN-C* Cabinets
Based on the manufacturers cut sheets for the referenced rooftop equipment, I have performed a rational analysis to determine the equipment roof live load rating capacity for compliance with minimum requirements per UL 60335 and UL 1995.
Analysis results demonstrate that the roof component for the referenced equipment exceeds minimum said requirements with the following maximum concentrated and uniform load rating capacities and panel deflections less than 0.6”:
a. Max static concentrated force of 200 lbs applied in the vertical direction at the most unfavorable location, distributed over a 6” diameter circular area.
b. Max uniform load of 35 psf distributed over the entire roof surface.
