FILLING METHOD USING MIXED REFRIGERANT INCLUDING TRANS-1, 3, 3, 3-TETRAFLUOROPROPENE |
摘要 |
An object of the present invention is to provide a method for filling a refrigerant mixture. This method enables composition changes of a non-azeotropic refrigerant mixture comprising HFO-1234ze(E) and HFC-32 during the transfer to fall within an acceptable range of refrigerant performance. The method for filling a refrigerant mixture comprising HFC-32 and HFO-1234ze(E), the HFC-32 being present in a liquid phase of the refrigerant mixture in an amount of 10 to 90 wt% based on 100 wt% of the total of the HFC-32 and HFO-1234ze(E), comprises, in transferring the refrigerant mixture in a liquid state to a target container or equipment from a feeding container, adjusting the proportion (initial composition) of the HFC-32 in the liquid phase of the refrigerant mixture in the feeding container immediately before the transfer to x + y 1 (minimum value) to x% (target upper-limit composition), so that the proportion of the HFC-32 in the liquid phase of the refrigerant mixture in the feeding container falls within a range from the target upper-limit composition (x) of the HFC-32 to the target upper-limit composition (x) - 4.0 wt% (target lower-limit composition) during initiation and completion of the transfer. |
