The superfrs requires an additional precooler
, The so-called cool down and warm up unit (cwu) due to its enormous cold mass of roughly 1 500 t.
For example, the working fluid exchanges heat at the precooler
At the heart of the breakthrough is the development of the precooler
, made from inconel 718, a strong and highly corrosion-resistant aerospace alloy.
allows the hot compressed air from the turbines to be processed at a substantially cooler temperature than was previously possible, which, in turn, cools the aircraft's interior and prime mission equipment, as well as positively affecting other secondary systems.
For evaporatively cooled condensers, consider the example of an evaporative precooler
added to an air-cooled condenser, at AHRI standard conditions, as discussed in the Emerging Technologies column in the October 2011 ASHRAE Journal.
A desiccant wheel system with precooler
can be added as an option.
Hot water dip followed by cooling--By using hot water bath and forced air precooler
(Rinac India Ltd.
It is a heat pump system consisting of a two-stage rotary compressor, an oil separator, a preheater, a precooler
, a gas cooler, four expansion valves, a test section, an auxiliary evaporator, and an accumulator.
One of the unique features of the control system is its two large flat-panel displays of the Precooler
temperatures that are large enough for the fork lift drivers to see as they zip by.
This AD requires revising the Airplane Flight Manual and eventual disconnection of the precooler
differential pressure switches.
Optional factory-mounted precooler
or valve station for economized operation.
The coarse product is then put through a precooler
where it is sprayed with liquid nitrogen at -320 [degrees] or 195 [degrees] C.
