This document is a comprehensive HVAC design and specifications package for the Tularosa Basin National Desalination Research Facility, prepared by Malcolm Pirnie, Inc., the engineer/architect, with Lacuna Construction Company, Inc., as the prime contractor. The package is dated December 2006 and includes detailed mechanical system plans, sections, and equipment schedules.

The HVAC system design encompasses multiple components across the main building and support structures. Key equipment includes two self-contained air-cooled air conditioning units (ACU-1 and ACU-2) serving the office and conference areas with capacities of 7,200 and 1,200 CFM respectively; three air-handling units (AHU-1, AHU-2, and AHU-3) for the mezzanine and various facility spaces; one air-cooled condenser (ACCU-1) supporting the main system; one self-contained evaporative unit (ECU-1) for the testing area; and six exhaust fans (EF-1 through EF-6) serving the lab roof, restrooms, storage, and other facility areas. The design also includes 20 variable air volume boxes (VAV-100 through VAV-129) distributed throughout offices, conference rooms, testing areas, and administrative spaces. The system utilizes refrigerant-based cooling and includes detailed specifications for ductwork, controls, and supporting mechanical infrastructure, with all equipment rated for standard commercial HVAC applications and voltage at 480/3 phase electrical supply.
