"WebThe thermodynamic cycle. The operating principle of a heat pump is based on the physical property that the boiling point of a fluid increases with pressure. By lowering pressure, a medium can be evaporated at low temperatures while an increase of pressure will lead to a high boiling point. The graph at the left side shows this principle.
