Abstract
A refrigeration cycle apparatus, refrigerating machine oil and refrigerant leakage prevention agent. The refrigeration cycle apparatus contains a working fluid which contains a refrigerant composition including a refrigerant and a refrigerating machine oil including resin particles of which D50 and D90/D10 are 2.0 μm to 10.0 μm and 4.0 to 14.0, respectively.
Claims2
A refrigeration cycle apparatus comprising a working fluid for a refrigerator, the working fluid comprising:
- a refrigerator oil comprising polytetrafluoroethylene particles having a D50 of 2.0 μm to 10.0 μm, a D90/D10 of 4.0 to 14.0, and a melt viscosity at 380° C. of 1×102 to 7×105 Pa·s;
- and
- a refrigerant composition comprising a refrigerant,
- wherein a particle size distribution of the polytetrafluoroethylene resin particles has a standard deviation of 3.0 μm to 8.0 μm.
A refrigerant leakage prevention agent comprising a refrigerator oil which comprises polytetrafluoroethylene resin particles having a D50 of 2.0 μm to 10.0 μm, a D90/D10 of 4.0 to 14.0 μm, and a melt viscosity at 380° C. of 1×102 to 7×105 Pa·s,
- wherein a particle size distribution of the polytetrafluoroethylene resin particles has a standard deviation of 3.0 μm to 8.0 μm.
