The discussion explores the feasibility of using hydraulic compression to create endothermic phenomena, particularly in the context of refrigeration systems. Participants examine the relationship between pressure, temperature, and the phase changes of water and other refrigerants, as well as the potential for miniaturized refrigeration systems for specific applications.
Participants generally agree that compression is a component of refrigeration but disagree on the effectiveness of water as a refrigerant and the feasibility of creating a compact refrigeration system. Multiple competing views remain regarding the use of hydraulic compression and the role of phase changes.
Limitations include the dependence on specific conditions for phase changes and the unresolved nature of how hydraulic compression might effectively replicate refrigeration principles.
This discussion may be useful for individuals interested in refrigeration technology, particularly in applications involving hydraulic systems or miniaturized cooling solutions.
Correct.deuel18 said:So in other words, correct me if I'm wrong, the compression process is just a fragment of the refrigeration process in which, the compression is the half part of the system?
Well, water is not a good working substance. You get better result using the phase transition from liquid to gas, then back to liquid (by compression), and this will not happen with water at the right temperature for reasonable pressures.deuel18 said:If the answer to my question above is yes, then, it implies that, in order to have a complete system of refrigeration, I must have a water compression part on one side and a water decompression part on the other side.
It is actually an advantage. The mass of fluid required is much less with a phase change. The pump can be significantly smaller.deuel18 said:Its seems rather difficult task, since phase change of evaporation and condensation requires tremendous amount of energy.
