Low Temperature Refrigeration
To start, let's define what we mean by low temperature refrigeration. The term low temperature refers to the cooler side of a general temperature range. In air conditioning, chilled water or glycol at 32°F (0°C) would be considered low. In industrial refrigeration, blast freezing at -50°F to -60°F (-45°C to -50°C) is considered low. In the realm of cryogenics, temperatures approaching -460°F or 0R (-273°C or 0 K) are suitably designated low. But none of these belong in the category discussed in this article.
