Save and compensate cold for hot-pipe system, widen hot-pipe system operation temperature area.But utility model patent ZL201210037082.8 exists
Utilize secondary heat exchange mode to provide cold for end under refrigeration mode, reduce cooling system efficiency；And ZL201210037332.8
When refrigeration mode switches with heat pipe pattern both of which, it may appear that system cold output instability, excessive unstable state.
About the computer-room air conditioning system utilizing power type separate heat pipe to couple with vapour compression refrigeration system at present also
Not it has been proposed that, the most not it has been proposed that widen heat pipe operation temperature area at spring, autumn transition season, according to heat pipe condensation deficiency
Locating on-demand refrigeration, the most various patterns switch in outside, and the output of end cold maintains steadily.Two are used for epipodium temperature
Air entry difference evaporating temperature realizes supercool function, it is ensured that under epipodium temperature operating mode, system has the air conditioning system of stable cold output
At present the most not it has been proposed that.
