Two heat exchanger E2 and the 4th heat exchanger E4 are required or the identical thermal power level specified, and the cubic metre of the first compressor C1 is also
Identical.Further, in the example that these are different, the rotating speed of two compressoies C1, C2 is identical, but this speed can root
Change according to operational circumstances, as described above.
Except the information having shown that in table 1, table 2 includes an indicated value, and it does not pass through the second heat exchange with being redirected
Device E2 air stream is correlated with relative to the mass percent of total air stream.Therefore, numerical value 0% represents that all air stream F are by second
Exchanger E2, numerical value 20% represent valve member 8 be positioned such that the 20% of the mass flow of air stream F be redirected and not
By the second heat exchanger E2 (therefore, the 80% of this mass flow passes through the second heat exchanger E2).
Table 2
It should be noted that the present invention only by change valve member 8 position, just can make device be easily adapted to different size or
Operating mode, in other words, makes device be applicable to the second heat exchanger E2 (for regulating the air in main cabin) and the 4th heat exchanger E4 (for cold
But battery) different thermal power level, and compressor C1, C2 have constant cubic metre (can be according to operation identical
Situation and change) rotate under speed.
