Jawaban:

Diketahui:

Koefisien performansi k = 6

T1 = 27°C = 300 K

Gunakan persamaan koefisian performasi pada mesin pendingin.

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell k space end cell equals cell space fraction numerator T subscript 2 over denominator left parenthesis T subscript 1 minus T subscript 2 right parenthesis end fraction end cell row 6 equals cell fraction numerator T subscript 2 over denominator left parenthesis 300 minus T subscript 2 right parenthesis end fraction end cell row cell 1800 minus 6 T subscript 2 end cell equals cell T subscript 2 end cell row cell 7 T subscript 2 end cell equals 1800 row cell T subscript 2 end cell equals cell 257 space K end cell end table end style

Sehingga diperoleh suhu yang paling rendah sebesar 257 K atau -15°C
