The enthalpy traces show that at elevated condenser temperatures, the difference between the saturated vapor enthalpy and the saturated liquid enthalpy for R290 is critical. For that reason, for an identical mass circulation amount of refrigerant, R290 is able to absorbing a larger degree of condensation heat, bringing about a https://baidubookmark.com/story20432866/the-ultimate-guide-to-r290-heat-pumps
