PROJECT OVERVIEWDrake Well Museum

• Site of the world’s first oil well, birthplace of the modern petroleum industry

• Located in Titusville, Pennsylvania

• Museum is undergoing renovations to improve the HVAC system and building envelope

Problem Definition

• Develop energy efficient HVAC system that meets Owner’s Requirements

• Determine heating and cooling loads

• Correctly size heating, ventilation, and air-conditioning systems

Project Constraints

• Comply with ASHRAE standards 55-2004, 62.1-2007, and 90.1- 2007

• Maintain 45% RH, 68-72˚F for collection spaces at all times

• Design must be flexible, sustainable, and achieve a minimum LEED Silver

• Temperature and humidity control must meet PHMC Category I criteria

Energy Efficiency

The VRF system has several key properties that substantially increases its energy efficiency.

• Heat recovery between outdoor units

• Simultaneous heating and cooling operation with heat recovery between indoor units

• COP of 5.0
