refrigeration
Artificial temperature reduction
Refrigeration is the process of cooling something, especially to preserve food or other perishables.
The term covers both the technology and the act: Before refrigeration, people relied on ice houses and root cellars.
Industrial refrigeration keeps warehouses cold; domestic refrigeration happens in your kitchen.
The word also applies to air conditioning systems that cool spaces rather than preserve goods.
