1. Introduction

The Atlantic Oceanographic and Meteorological Laboratory, located on Virginia Key Florida is a 6-story (5 floors and basement) research facility owned by the National Oceanic and Atmospheric Administration. The facility is served by a single York Codepack Chiller system (which replaced the facilities original chiller), located in the 4th floor, is connected to a cooling tower, via condenser water pumps and chilled water pumps. The main chiller is in good working order. An off peak thermal ice storage chiller and storage system, located in the ground level, was added to the plant via a program with Florida Power & Light (FP&L). There are currently 2 years remaining on this 10-year energy services project arrangement with FP&L.

2. Scope This Statement of Work (SOW) details the requirements for replacement, installation and testing of mechanical and electrical components to change the coils system inside the ground level chiller.

3. General

3.1. Chiller specifications

The ground level chiller is located on ground level, close to the south side of the building towards the Rickenbacker Causeway.

• Volts/Ph/HZ: 460V/3/60Hz

• Tonnage: 180 tons

• Model Number: YCAS0180EC46YFA

• Refrigerant: R22

NOTES:

1. Placement on a level surface free of obstructions (including snow, for winter operation) or air recirculation ensures rated performance, reli-able operation and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable air flow patterns and possible diminished performance. YORK’s unit controls will optimize operation without nuisance high pressure safety cutout; however, the system designer must consider potential performance degradation. Access to the unit control center assumes the unit is no higher than on spring isolators. Recommended minimum clearances: Side to wall - 6'; rear to wall - 6'; control panel end to wall - 4'; top

- no obstructions allowed; distance between adjacent units - 10'. No more than one adjacent wall may be higher than the unit.
