Refrigeration, an Uncommon card

The card carries these facts from its Wikipedia article.

• Early refrigeration uses consumable coolants such as ice and dry ice, while modern refrigeration is a self-sustaining heat exchanger process by which thermal energy is transferred against the temperature gradient via the use of a heat-transfer working fluid, which absorbs heat from a low-temperature medium and releases it to another higher-temperature medium, typically involving active phase…
• Energy transfer in refrigeration is traditionally driven by physical means, but it can also be driven by heat pump, magnetism, electricity, laser cooling, or other means.
• Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, and cool store air conditioning.
