Evaporative cooling chambers (ECCs), also known as "zero energy cool chambers" (ZECCs), are a type of evaporative cooler, which are simple and inexpensive ways to keep vegetables fresh without the use of electricity. Evaporation of water from a surface removes heat, creating a cooling effect, which can improve vegetable storage shelf life.
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.
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).
An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.
Most of the land that makes up the region was originally owned by the Kern County Land Company. That company later became Tenneco West and is currently known as Castle and Cooke. Growth started in the early 1950s but accelerated by the 1960s. Most of the growth in Bakersfield between the 1960s and 1980s occurred in the southwest. [1]
Vacuum cooling is a rapid cooling technique for any porous product that has free water and uses the principle of evaporative cooling.Vacuum cooling is generally used for cooling food products that have a high water content and large porosities, due to its efficacy in losing water from both within and outside the products.
Later, additional districts were added to East Bakersfield and the Southeast. [3] In 1984, a third focus was added to the department. The city created the Bakersfield Historical Preservation Commission. Traditionally, historical identification and preservation fell to private organizations (such as the Kern County Historical Society).
Some modern tests have shown that the interior of the safe would achieve temperatures 3–9 °C (dependant on breeze) cooler than the atmospheric temperature during the middle of the day. [2] It was usually placed on a veranda where there was a breeze. The Coolgardie safe was a common household item in Australia until the mid-twentieth century.
