Stanford’s Heat Recovery System

Stanford University has implemented an innovative heat recovery system that significantly reduces its energy consumption and environmental impact. This system captures and reuses waste heat generated from various sources on campus, transforming it into valuable energy for heating buildings, providing hot water, and powering other processes.

Technologies Employed

Stanford’s heat recovery system utilizes a variety of technologies to capture and utilize waste heat effectively. These technologies include:

• Heat exchangers: These devices transfer heat from one fluid to another without direct contact. In Stanford’s system, heat exchangers are used to capture waste heat from sources like exhaust air from buildings and hot water from cooling towers. This captured heat is then transferred to a secondary fluid, such as water, which can be used for heating or other purposes.
• Absorption chillers: These chillers use heat to drive a refrigeration cycle, producing chilled water for air conditioning. Stanford’s system utilizes waste heat from sources like natural gas combustion or industrial processes to power absorption chillers, reducing the need for electricity-powered chillers.
• Thermal storage: This technology stores heat for later use. Stanford uses thermal storage tanks to store excess heat captured from various sources. This stored heat can be used during peak demand periods or when other sources are unavailable.

Waste Heat Sources

Stanford’s heat recovery system captures waste heat from various sources on campus, including:

• Exhaust air from buildings: Air conditioning and ventilation systems in buildings often exhaust warm air. Heat exchangers capture this waste heat and transfer it to a secondary fluid for heating or other applications.
• Hot water from cooling towers: Cooling towers used for air conditioning systems release hot water. Heat exchangers capture this heat and transfer it to a secondary fluid for heating or other applications.
• Industrial processes: Certain industrial processes, such as steam generation or chemical reactions, produce waste heat. This heat can be captured and used for heating buildings or powering other processes.
• Natural gas combustion: The combustion of natural gas for heating or power generation produces significant waste heat. Stanford uses heat exchangers to capture this heat and transfer it to a secondary fluid for heating or other applications.

Applications of Recovered Heat

The recovered heat from Stanford’s system is used for various purposes, including:

• Heating buildings: Recovered heat is used to warm air and water for heating buildings during the winter months, reducing the need for fossil fuel-based heating systems.
• Providing hot water: Recovered heat is used to preheat water for showers, sinks, and other uses, reducing the energy required to heat water from cold sources.
• Powering absorption chillers: Recovered heat is used to power absorption chillers, which provide chilled water for air conditioning, reducing the need for electricity-powered chillers.
• Other processes: Recovered heat can also be used to power other processes, such as greenhouse heating or industrial processes.
