refrigeration
Let an agent handle refrigeration by technology, food safety temperatures, refrigerant regulation, energy use and safety.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle refrigeration by technology, food safety temperatures, refrigerant regulation, energy use and safety.
The process of removing heat from a space or substance to lower its temperature, used in refrigerators, freezers, cold storage, air conditioning and cryogenics, usually via vapour-compression cycles with refrigerants.
What it is for: Food preservation, medicines, comfort cooling and industry.
It can be explain refrigeration cycles; keep food and medicines at safe temperatures; understand refrigerant rules and leaks; improve energy efficiency.
Distinguishing features
Moves heat against a gradient
Uses refrigerants
Energy-intensive
Critical for food safety
What it looks like
Fridges, freezers, cold rooms, compressors and cooling units.
Physical character
typical fridge temperature: about 0-5 degC - food safety guidance
typical freezer temperature: about -18 degC
How it is recognised
Compressors, condensers and evaporators
Temperature displays
Ventilation moves air without cooling it below ambient
