<p>A mechanical vapour recompression heat pump system wherein the working fluid is a saturated fluorohydrocarbon or fluorohydrocarbon ether having from 3to 5 carbon atoms or a fluorinated amine containing up to 6 carbon atoms and having the formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="24" wi="50" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein each of X and X', independently, represents hydrogen or fluorine,
<UnorderedLists id="ula01" listStyle="none"><ListItem>R represents hydrogen or a lower alkyl radical</ListItem><ListItem>n represents an integer from 1 to 4,</ListItem><ListItem>each of m and q represents an integer from 0 to 2,</ListItem><ListItem>p represents an integer from 0 to 4 provided that p is not zero when X' is fluorine, and</ListItem><ListItem>r represents an integer from 1 to 3;</ListItem></UnorderedLists>or the formula:
<Chemistry id="chema02" num="0002"><Image id="ia02" he="10" wi="45" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein W represents hydrogen or fluorine, a represents an integer from 3 to 5, b represents an integer from 1 to 3 and c represents an integer from 0 to 2 provided that c is not zero when W is fluorine.</p> |
