An ice pack Shipment of vaccine in insulated box with gel packs An ice pack or gel pack is a portable bag filled with water, refrigerant gel , or liquid, meant to provide cooling. They can be divided into the reusable type, which works as a thermal mass and requires freezing, or the instant type, which cools itself down using chemicals but can ...
A thermal bag to keep pizzas being delivered hot was invented by Ingrid Kosar in 1983, and is commonly used now. [ 5 ] [ 6 ] A cool box is very similar in concept, but typically larger and in the form of a rigid box.
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
Maximum storage time for (pre-frozen) food is 1 week min temperature: −12 °C (10 °F). Maximum storage time for (pre-frozen) food is 1 month min temperature: −18 °C (0 °F). Maximum storage time for (pre-frozen) food is between 3 and 12 months depending on type (meat, vegetables, fish, etc.) min temperature: −18 °C (0 °F).

The rapid evaporation to the moving air could keep the milk sufficiently cool. [2] Prior to the widespread usage of home refrigeration, iceboxes were used for the cool storage of food items. [5] The California cooler could be used to free up valuable space in the ice box by storing items that did not require as much refrigeration.
The scope of this thermal energy application is wide-ranging of solar heating, hot water, heating rejection (i.e., cooling tower), and dry cooler circuitry thermal energy storage applications. Since PCMs transform between solid–liquid in thermal cycling, encapsulation [ 21 ] naturally became the obvious storage choice.
