本发明提供一种制冷机用工作流体组合物，其是将氨制冷剂与在该氨制冷剂中溶解性极其优异的润滑油混合而成的。该工作流体组合物包含氨和一种或多种聚醚化合物的混合物，该制冷机的特征在于构成使该工作流体组合物循环的制冷循环或热泵循环。
The present invention provides a working fluid composition for a refrigerating machine obtained by mixing an ammonia refrigerant with a lubricating oil which is extremely excellent in solubility with the ammonia refrigerant. The working fluid composition comprises a mixture of ammonia and one or more kinds of polyether compounds; the refrigerating machine is characterized by constituting a refrigerating cycle or a heat pump cycle through which the working fluid composition is circulated.
