There are disclosed refrigeration working fluid compositions comprising tetrafluoroethane refrigerants and certain polyol esters of C7-C10 branched alkanoic acids or mixtures of such branched acids with linear C7-C10 monoalkanoic acids. The polyols are mono-, di- or technical grade pentaerythritol or ...
Film cooling in combination with regenerative cooling is presently considered as an efficient method to guarantee safe operation of liquid rocket engines having higher heat flux densities for long duration. This paper aims to b
A direct expansion type heating and cooling system is provided with means for supplying a heat exchange coil with proportioned mixtures of liquid refrigerant and hot refrigerant gas. Constant temperature is maintained in the conditioned area at any point from full cooling to full heating, by proporti...

Air cooling requires significant energy and takes up a lot of space, so HPC operation with air cooling is only possible in 2 U racks. Through liquid cooling, the HPC chip can now be operated in a 1 U rack for the first time, resulting in a 50% reduction in footprint. The success ...

liquid; cooling and directing a first part of the third liquid into the lights-ends fractionation column, to thereby condense C 2 's and heavier components while the methane is evaporated in the light-ends fractionation column to thereby obtain fourth residue vapor and liquid, heating and ...
The crystals thus formed are buoyant and float up, thereby displacing heavier liquid downward and releasing gravitational energy. Here we show that distillation interrupts the cooling for billions of years and explains all the observational properties of the unusual delayed population. With a steady ...
Experiments have been carried out to investigate the use of direct contact cooling techniques for the separation of different organic mixtures by melt suspension crystallization. Air as a gas coolant, water and sodium chloride solution as liquid coolants were used at atmospheric pressure to cool down...
