A crisper drawer (also known as a crisper) is a compartment within a refrigerator designed to prolong the freshness of stored produce. Crisper drawers have a different level of humidity from the rest of the refrigerator, optimizing freshness in fruits and vegetables. Some can be adjusted to either prevent the loss of moisture from produce, or to allow ethylene gas produced by certain fruits to escape in order to prevent them from rotting quickly.
The first known use of the word "crisper" in relation to a crisper drawer was in 1835. [1]
Crisper drawers operate by creating an environment of greater humidity than the rest of the refrigerator. Many crisper drawers have a separate humidity control which closes or opens a vent in the drawer. When the vent is in the closed position, airflow is shut off, creating greater humidity in the drawer. High humidity is optimal for the storage of leafy or thin-skinned vegetables. When the vent is in the open position, airflow keeps humidity in the crisper drawer low, which is beneficial for the storage of fruits. Additionally, because some fruits emit high levels of ethylene gas, the open vent allows the ethylene gas to escape, preventing these foods from rotting. The ability to separate low-humidity fruits from high-humidity vegetables using the different crisper drawers also prevents ethylene gas from damaging the latter. [2] [3] [4] Crisper drawers which do not have a humidity control are, by default, high humidity crispers. [2]
Appliance manufacturers have reported that many refrigerator owners are unaware of the purpose or operation of crisper drawers. [2] [5] A 2010 survey commissioned by Robert Bosch GmbH found that 55 percent of surveyed Americans "admit to not knowing how to use their crisper drawer controls". [6]
In the UK, sources often use the term "crisper drawer" in conjunction with a nearby explanation, like the Vegetable Expert advice website calling them "special compartments or 'crisper drawers' to store fruits and vegetables", [7] the consumers' organisation Which? calling it a "salad crisper drawer [...] for storing your fruit and veg", [8] and some appliance companies calling it a "fridge/freezer salad crisper".
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.
The Japanese kitchen is the place where food is prepared in a Japanese house. Until the Meiji era, a kitchen was also called kamado and there are many sayings in the Japanese language that involve kamado as it was considered the symbol of a house. The term could even be used to mean "family" or "household". Separating a family was called kamado wo wakeru, or "divide the stove". Kamado wo yaburu means that the family was broken.
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).

In refrigerators, defrosting is the removal of frost and ice.
Kegerator, a portmanteau of the words keg and refrigerator, is a refrigerator that has been designed or altered to store and dispense kegs.
Modified atmosphere packaging (MAP) is the practice of modifying the composition of the internal atmosphere of a package in order to improve the shelf life. The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen. In food, oxygen is readily available for lipid oxidation reactions. Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. From a microbiological aspect, oxygen encourages the growth of aerobic spoilage microorganisms. Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological spoilage. Oxygen scavengers may also be used to reduce browning due to lipid oxidation by halting the auto-oxidative chemical process. Besides, MAP changes the gaseous atmosphere by incorporating different compositions of gases.

Auto-defrost, automatic defrost or self-defrosting is a technique which regularly defrosts the evaporator in a refrigerator or freezer. Appliances using this technique are often called frost free, frostless, or no-frost.
Cold chain is defined as the series of actions and equipment applied to maintain a product within a specified low-temperature range from harvest/production to consumption. An unbroken cold chain is an uninterrupted sequence of refrigerated production, storage and distribution activities, along with associated equipment and logistics, which maintain a desired low-temperature interval to keep the safety and quality of perishable or sensitive products, such as foods and medicines. In other words, the term denotes a low temperature-controlled supply chain network used to ensure and extend the shelf life of products, e.g. fresh agricultural produce, seafood, frozen food, photographic film, chemicals, and pharmaceutical products. Such products, during transport and end-use when in transient storage, are sometimes called cool cargo. Unlike other goods or merchandise, cold chain goods are perishable and always en-route towards end use or destination, even when held temporarily in cold stores and hence commonly referred to as "cargo" during its entire logistics cycle. Adequate cold storage, in particular, can be crucial to prevent quantitative and qualitative food losses.

An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers to the stand-alone appliance.
A pot-in-pot refrigerator, clay pot cooler or zeer is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot containing an inner pot within which the food is placed. The evaporation of the outer liquid draws heat from the inner pot. The device can cool any substance, and requires only a flow of relatively dry air and a source of water.
A root cellar, fruit cellar or earth cellar is a structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods. Its name reflects the traditional focus on root crops stored in an underground cellar, which is still often true; but the scope is wider, as a wide variety of foods can be stored for weeks to months, depending on the crop and conditions, and the structure may not always be underground.
A kimchi refrigerator is a refrigerator designed specifically to meet the storage requirements of kimchi and facilitate different fermentation processes. The kimchi refrigerator aims to be colder, with more consistent temperature, more humidity, and less moving air than a conventional refrigerator, providing the ideal environment for fermentation of kimchi. Some models may include features such as a UV Sterilizer.

A refrigerator death is death by suffocation in a refrigerator or other air-tight appliance. Because, by design, such appliances are air-tight when closed, a person entrapped inside will have a low supply of oxygen. Early refrigerators could only be opened from the outside, making accidental entrapment a possibility, particularly of children playing with discarded appliances; many such deaths have been recorded. Modern designs close with a magnetic mechanism that can be opened from the inside, reducing the danger of accidental entrapment.
