Icebox used in cafés of Paris in the late 1800s. An icebox (also called a cold closet) 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 ...
The ground floor formerly housed the business centers, the basement was used as stores and the upper floors were used for residential purpose by the owner and his family. Even at the time it was built, the building had many modern facilities such as refrigerator that functioned on ice, telephones, and attached toilets and bathrooms with each room.
Yakhchāl of Moayedi, Iran. A yakhchāl (Persian: یخچال 'ice pit'; yakh meaning 'ice' and chāl meaning 'pit') 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.
Kelvinator ad from 1920 Kelvinator refrigerator, c. 1926 The enterprise was established on September 18, 1914, in Detroit , Michigan , United States, by engineer Nathaniel B. Wales , who introduced his idea for a practical electric refrigeration unit for the home to Edmund Copeland and Arnold Goss.
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
Temperature control of the sample within the cryostat is typically performed by controlling the flow rate of cryogen into the cryostat together with a heating wire attached to a PID temperature control loop. The length of time over which cooling may be maintained is dictated by the volume of cryogens available.
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
