Applying an Intelligent, High-Efficiency Energy Recovery System

January 22, 2015
1 p.m. – 2 p.m.
Eastern Standard Time

An intelligent, high-efficiency energy recovery system uses strategies that make it more efficient than other conventional systems such as run-around loops, energy recovery wheels, refrigerant heat pipes, or plate heat exchangers. It uses special coils with a high water pressure drop to keep turbulent flow through a wide range of flow rates, allowing a variable flow system. This system uses lower gallons per minute compared to a run-around loop resulting in similar pump horsepower. A single coil in the air handler performs energy recovery, preheat, and cooling by using one piping system with the correct temperature water needed to achieve the required air temperature. The pump skid has a control system that monitors supply and exhaust temperatures, heat recovery temperatures, and chilled and heating water temperatures to optimize the energy recovery water temperature, pump speed, and control valve operation. This system performs a numerical simulation once per second using three dimensional performance maps of coils, pumps, and valves.

During this webinar, Sean Convery of Cator, Ruma, & Associates and Mark Labac of Edge Mechanical Systems, Inc. will share how the University of Colorado Boulder Sustainability, Energy and Environment Complex (SEEC) implemented an intelligent, high-efficiency heat recovery system with evaporative cooling. In addition to the features of the system, they will share the financial and energy savings achieved by this project.

During the webinar, the presenters will:

  • Identify the conventional heat recovery systems used in laboratories along with their benefits and drawbacks.
  • Describe an intelligent, high-efficiency heat recovery system and its benefits.
  • Explain how to apply an intelligent, high-efficiency heat recovery system while keeping it cost neutral.
  • Share how the University of Colorado Boulder implemented a high-efficiency heat recovery system and the resulting energy savings it achieved.
