Effectiveness of using zeotropic working fluids in heat pumps

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 (Tni > 10 K) is an effective way of making...

Description
Summary: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 (Tni > 10 K) is an effective way of making the thermal processes more efficient.
