Liquid-injected machines have a higher discharge mass flow rate of vapor so the quantity of heat recoverable is often greater than thermosiphon
or external oil cooled packages.
As discussed above, the thermosiphon
operates on a heat pipe principles.
The capacity of relief valves for the refrigerant-side of a thermosiphon
oil cooler should be determined based on the maximum rate of refrigerant vapor generated within the oil cooler driven by heat input from likely scenarios that could contribute to overpressure conditions on the refrigerant-side of the oil cooler.
(6) The values of the flow rate at other time periods are estimated based on the photothermal performance of the gravitative loop thermosiphon
Water circulation may occur in two ways: forced by pump or by natural convection thermosiphon
, where the water is at the collector to be heated by solar radiation (Kalogirou, 2014).
More recently a 12 L deuterium CNS was installed at FRM-II Germany and OPAL was commissioned with a 20 L deuterium CNS; both designs use a thermosiphon
for moderator cooling.
 drew a conclusion without consideration of frictional pressure that C[O.sub.2] thermosiphon
could produce similar amount of electric power with the same quantity of heat extraction compared to water but with simpler surface equipment.
The heat flux rate would be such that the liquid is evaporated over the length of the tube, similar to the case for a thermosiphon
flooded evaporator, as highlighted in Figure i.
The circulation in the buffer fluid circuit occurs according to the Thermosiphon
principle, or via forced circulation e.g.
This temperature range is beyond the supply capacity of conventional thermosiphon
and evacuated solar collectors.
systems are another type of passive design, and use the effect of hot water rising above cold to circulate the hot water to a storage tank, which can even be located inside a house so it loses less heat to the ambient temperature.
"The engine end is attached physically to a thermosiphon
, a copper pipe that wraps itself around the inside of the freezer." There's no mixing of the refrigerant.
