Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one. Refrigeration is an artificial, or human-made, cooling method.
A grotto is a natural or artificial cave used by humans in both modern times and antiquity, and historically or prehistorically. Naturally occurring grottoes are often small caves near water that are usually flooded or often flooded at high tide. Sometimes, artificial grottoes are used as garden features. The Grotta Azzurra at Capri and the grotto at Tiberius' Villa Jovis in the Bay of Naples are examples of popular natural seashore grottoes.
A dugout or dug-out, also known as a pit-house or earth lodge, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archaeologists, and the same methods have evolved into modern "earth shelter" technology.
A refrigerator, colloquially fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. Refrigeration is an essential food storage technique around the world. The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is 3 to 5 °C. A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half. The United States Food and Drug Administration recommends that the refrigerator be kept at or below 4 °C (40 °F) and that the freezer be regulated at −18 °C (0 °F).
A windcatcher, wind tower, or wind scoop is a traditional architectural element, originated in Iran (Persia), used to create cross ventilation and passive cooling in buildings. Windcatchers come in various designs, depending on whether local prevailing winds are unidirectional, bidirectional, or multidirectional, on how they change with altitude, on the daily temperature cycle, on humidity, and on how much dust needs to be removed. Despite the name, windcatchers can also function without wind.
A yakhchāl is an ancient type of ice house, which also made ice. They are primarily found in the Dasht-e Lut and Dasht-e-Kavir deserts, whose climates range from cold (BWk) to hot (BWh) desert regions.
An icebox is a compact non-mechanical refrigerator which was a common early-twentieth-century kitchen appliance before the development of safely powered refrigeration devices. Before the development of electric refrigerators, iceboxes were referred to by the public as "refrigerators". Only after the invention of the modern electric refrigerator did early non-electric refrigerators become known as iceboxes. The terms ice box and refrigerator were used interchangeably in advertising as long ago as 1848.
A hut is a small dwelling, which may be constructed of various local materials. Huts are a type of vernacular architecture because they are built of readily available materials such as wood, snow, ice, stone, grass, palm leaves, branches, clay, hides, fabric, or mud using techniques passed down through the generations.
Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. Waste heat from industrial process can similarly be stored and be used much later or the natural cold of winter air can be stored for summertime air conditioning.
Ardgillan Castle is a country house near Balbriggan, County Dublin, Ireland. It is set in the 200-acre (0.81 km2) Ardgillan Demesne, a public park in the jurisdiction of Fingal County Council.
District cooling is the cooling equivalent of district heating. Working on broadly similar principles to district heating, district cooling delivers chilled water to buildings like offices and factories. In winter, the source for the cooling can often be seawater, so it is a cheaper resource than using electricity to run compressors for cooling. Alternatively, District Cooling can be provided by a Heat Sharing Network which enables each building on the circuit to use a heat pump to reject heat to an ambient ground temperature circuit.
Frozen dessert is a dessert made by freezing liquids, semi-solids, and sometimes solids. They may be based on flavored water, on fruit purées, on milk and cream, on custard, on mousse (semifreddo), and others. It is sometimes sold as ice-cream in South Asia and other countries.
Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. Alternative power sources such as solar can also use the technology to store energy for later use. This is practical because of water's large heat of fusion: one metric ton of water can store 334 megajoules (MJ) of energy, equivalent to 93 kWh.
The Archaic–Early Basketmaker Era was an Archaic cultural period of ancestors to the Ancient Pueblo People. They were distinguished from other Archaic people of the Southwest by their basketry which was used to gather and store food. They became reliant on wild seeds, grasses, nuts, and fruit for food and changed their movement patterns and lifestyle by maximizing the edible wild food and small game within a geographical region. Manos and metates began to be used to process seeds and nuts. With the extinction of megafauna, hunters adapted their tools, using spears with smaller projectile points and then atlatl and darts. Simple dwellings made of wood, brush and earth provided shelter.
The ice trade, also known as the frozen water trade, was a 19th-century and early-20th-century industry, centering on the east coast of the United States and Norway, involving the large-scale harvesting, transport and sale of natural ice, and later the making and sale of artificial ice, for domestic consumption and commercial purposes. Ice was cut from the surface of ponds and streams, then stored in ice houses, before being sent on by ship, barge or railroad to its final destination around the world. Networks of ice wagons were typically used to distribute the product to the final domestic and smaller commercial customers. The ice trade revolutionised the U.S. meat, vegetable and fruit industries, enabled significant growth in the fishing industry, and encouraged the introduction of a range of new drinks and foods. It only flourished in the time between the development of reliable transportation and the development of widespread mechanical refrigeration.
The Knickerbocker Ice Company was an ice company based in New York State during the 19th century.
Bastani, locally known as bastani sonnati or bastani sonnati zaferani, is an Iranian ice cream made from milk, eggs, sugar, rose water, saffron, vanilla, and pistachios. It is known widely as Persian ice cream. Bastani often contains flakes of frozen clotted cream. Sometimes, salep is included as an ingredient.
A game larder, also sometimes known as a deer or venison larder, deer, venison or game house, game pantry or game store, is a small domestic outbuilding where the carcasses of game, including deer, game birds, hares and rabbits, are hung to mature in a cool environment. A feature of large country houses and sporting lodges in Britain and parts of northern Europe from the 18th century, game larders continue to be used by shooting estates.

The Park Crescent West ice well is a 9.5m deep underground brick structure in the City of Westminster, London, England. It was built by Samuel Dash in 1780 for the storage of ice gathered from local ponds and canals. The structure came into the ownership of William Leftwich, a leading figure in the London ice trade, who used it to store imported Norwegian ice which he sold to the food and drinks industry. The well was abandoned in the mid-to-late 19th century and covered over. It was rediscovered in good condition during development works in 2014. The well was listed as a scheduled monument in 2015 and there are plans to make it available for visits by the general public.
