1856 – James Harrison patented an ether liquid-vapour compression refrigeration system and developed the first practical ice-making and refrigeration room for use in the brewing and meat-packing industries of Geelong, Victoria, Australia. 1856 – August Krönig simplistic foundation of kinetic theory of gases.
Such a system usually runs in ice-making mode for 16 to 18 hours a day and in ice-melting mode for six hours a day. Capital expenditures are minimized because the chillers can be just 40 - 50% of the size needed for a conventional design. Ice storage sufficient to store half a day's rejected heat is usually adequate.
His 1856 patent was for a vapour-compression system using ether, alcohol, or ammonia. He built a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Victoria, and his first commercial ice-making machine followed in 1854. Harrison also introduced commercial vapour-compression refrigeration to ...

In refrigerators, defrosting (or thawing) is the removal of frost and ice. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency. Over time, as the door is opened and closed, letting in new air, water vapour from the air condenses on the cooling elements within the cabinet.
An all-in-one (AIO) cooling unit, installed in a case DIY water cooling setup showing a 12 V pump, CPU waterblock and the typical application of a T-Line Schematic of a regular liquid cooling setup for PCs. Liquid cooling is a highly effective method of removing excess heat, with the most common heat transfer fluid in desktop PCs being ...
A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation , to remove solvents using a rotary evaporator , or to perform a chemical reaction below room temperature ...
