Synchronous condenser installation at Templestowe substation, Melbourne, Victoria, Australia. Built by ASEA in 1966, the unit is hydrogen-cooled and capable of three-phase power at 125 MVA . In electrical engineering , a synchronous condenser (sometimes called a syncon , synchronous capacitor or synchronous compensator ) is a DC-excited ...
The Likens-Nickerson apparatus is a piece of laboratory glassware devised by Sam T. Likens and Gail B. Nickerson for the detection of hop oil constituents in 1964. [1] The apparatus performs a simultaneous steam distillation and extraction.
(Typical steam to condenser would be at a few millimeters absolute pressure and on the order of 5 °C (41 °F) hotter than the cooling water temperature, depending on the condenser capacity.) In cogeneration this steam exits the turbine at a higher temperature where it may be used for process heat, building heat or cooling with an absorption ...
Synchronous motors fall under the category of synchronous machines that also includes synchronous generators.Generator action occurs if the field poles are "driven ahead of the resultant air-gap flux by the forward motion of the prime mover".
Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. [1] Similar to ductless mini-split systems, VRFs use refrigerant as the primary cooling and heating medium, and are usually less complex than conventional chiller-based systems.
The condenser coil of a refrigerator. In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In doing so, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many ...
If the condenser can be made cooler, the pressure of the exhaust steam is reduced and efficiency of the cycle increases. Diagram of a typical water-cooled surface condenser. [10] [11] [14] [15] The surface condenser is a shell and tube heat exchanger in which cooling water is circulated through the tubes.
The uncondensed steam is fed into a condenser, mixed with condensate from the separators, fed by the first-stage condensate pump to a chemical (ion-exchange) purifier, then by a second-stage condensate pump to four deaerators where dissolved and entrained gases are removed; deaerators also serve as storage tanks for feedwater.
