Dramatic Energy and Noise Reduction in New Ultra-Low Temperature Freezer Design
Dave Withee, Coollabsfande.com
Excessive energy consumption and noise pollution are considered nearly unavoidable constants within the laboratory environment, especially as laboratory use has shifted increasingly from chemistry to biology. However, it doesn't have to be that way, at least in the realm of ultra-low temperature (-85°C) freezers.
Typical ultra-low freezers use two compressors. This poster presentation chronicles the development and results of an innovative single-compressor design for use with ultra-low temperature freezers. The design is the result of collaboration between a Danish and a Japanese engineering team. The new single-compressor concept utilizes true single-stage technology. The results include exceptional benefits in four key areas:
- Energy savings of 35 to 50 percent
- Low heat dissipation
- Noise reduction
- Small footprint for improved space utilization
Carbon footprint reduction can and should come from all areas of the laboratory. Now, ultra-low temperature freezers will participate in the continued development of sustainability within the laboratory environment.
