Compression under cryogenic conditions significantly reduces the power consumption of compression, but it outputs the same amount of enthalpy (cold loss) as the power consumption of compression to the cryogenic system. The negative power is responsible for the cold loss!From the point of view of effective energy, the power consumption of cryogenic compression is equal to the effective energy of cryogenic compression power consumption and refrigeration loss. Therefore, it can be said that cryogenic compression and cryogenic compression are equivalent, and cryogenic compression is not particularly advantageous, and specific problems need to be analyzed.
The advantage of ambient temperature compression is that the cost of the compressor can be reduced, and sectional compression can be used to save compression power when compression is relatively large. Of course, the disadvantage is obvious, that is, the reheating equipment needs to be increased relative to cryogenic compression, and at the same time, the positive and reverse resistance will increase the compression ratio and the cold loss caused by the temperature difference at the hot end of the reheating equipment.
