Factors affecting the performance, energy consumption, and carbon footprint for ultra low temperature freezers: case study at the National Institutes of Health

World Review of Science, Technology and Sustainable Development, 2013
The National Institutes of Health (NIH) recognises an opportunity to significantly reduce the energy consumption and its carbon footprint from plug load equipment can be realised by managing –86°C ultra low temperature (ULT) freezers. Energy meters were installed on ULT freezers operating in actual laboratory conditions to determine how their energy ...

Principal effective factors on the dynamic pull-down performance of a zeotropic mixture based ultra-low temperature freezer

Applied Thermal Engineering, 2021
Abstract Cascade technology with less than −80 ℃ has risen sharply with the development of the biomedical industry. Although appropriate refrigerant-couples and corresponding improving-approaches have been presented, dynamic parameters of operating stability and security rather than COP are more important to evaluate an ultra-low temperature freezer.

Experimental investigation on the pull-down performance of a -80°C ultra-low temperature freezer

International Journal of Refrigeration, 2020
Abstract This paper presents an experimental investigation on the pull-down performance of a -80°C ultra-low temperature freezer. Experiments were conducted in a two-stage cascade refrigeration system with an inner recuperative heat exchanger in low temperature cycle (LTC).

A procedure for converting an ultra-low temperature freezer for freezing biological material

Canadian Journal of Plant Science, 1991
A plan for a precise temperature-controlled freezing chamber for studying plant freezing responses to temperatures between 0° and −70 °C is described. The chamber is especially useful for conducting biological freezes requiring slow freeze-thaw rates and rapid response times. Key words: Ultra-low temperature freezer, controlled freezing chamber
