Abstract

As alternatives to refrigerants with a high global warming potential, blends of two or more refrigerants are being utilized as working fluids in heat-pump, air-conditioning, and refrigeration systems. Generally, these blends form zeotropes, which show temperature and composition changes during evaporation, condensation, or flashing process whether it be intended (i.e., through an expansion device) or unintended (e.g., a leak from a container or system). REFLEAK simulates leak and recharge processes for refrigerant zeotropic blends. This Windows- based simulation model provides an easy-to-use package that allows estimation of composition changes of zeotropic blends in leak and recharge processes for either vapor or liquid leaks under isothermal or adiabatic conditions.
