Asphyxia The displacement of oxygen in a room by the denser refrigerant. Azeotrope A blend of two or more components whose equilibrium vapor phase and liquid phase composition are the same at a given pressure. These refrigerants are given a 500-series ASHRAE designation and behave like a single refrigerant. They can be charged as a liquid or vapor. Bubble Point The temperature at which the non-azeotropic blend first begins to evaporate (boil). Capillary Tube A passive throttling device co...
