Description

technical field

[0001] The present disclosure relates to the technical field of refrigeration equipment, in particular to a mixed working medium refrigeration system and a dehumidifier. Background technique

[0002] The dual-temperature cycle can reduce the irreversible loss in the heat exchange process and improve the energy efficiency of the system, and to a certain extent, it can realize the cascade utilization of energy, so it has attracted widespread attention. In particular, the dual-temperature circulation system constructed by the mixed working fluid can reduce the irreversible loss in the heat exchange process and improve the energy efficiency of the system. However, considering the heat transfer characteristics of the mixed working fluid, there are two problems: there are difficult-to-condensate particles in the condensation process. Low-boiling-point gases will reduce the condensation heat transfer coefficient; the dual-temperature temperature is completely depend...
