We analyze the thermodynamic cycles of heat pumps using monofluids and zeotropes are used as the working fluids. We show that selecting zeotropic fluids with favorable thermodynamic properties and substantially nonisotropic phase transformation processes (ΔTni > 10 K) is an effective way of making the thermal processes more efficient.
