1. A compressor which uses a refrigerant containing 1,1,2-trifluoroethylene as a working fluid, and uses a polyol ester oil as a compressor lubricating oil, comprising
a fixed scroll and a revolving scroll each having a spiral lap rising from an end plate;
a compression chamber which is formed by meshing the fixed scroll and the revolving scroll;
a discharge hole which is provided at a center position of the end plate of the fixed scroll, and is open to a discharge chamber;
a bypass hole which is provided in the end plate of the fixed scroll, and communicates with the compression chamber and the discharge chamber at a timing different from a timing at which the compression chamber communicates with the discharge hole; and
a check valve which is provided in the bypass hole, and allows a flow from a compression chamber side to a discharge chamber side,
wherein the working fluid is selected from the group consisting of
a mixed working fluid comprising 1,1,2-trifluoroethylene and difluoromethane, the difluoromethane being at least 30% by weight to at most 60% by weight in the mixed working fluid,
a mixed working fluid comprising 1,1,2-trifluoroethylene and tetrafluoroethane, the tetrafluoroethane being at least 30% by weight to at most 60% by weight in the mixed working fluid, and
a mixed working fluid comprising 1,1,2-trifluoroethylene, difluoromethane, and tetrafluoroethane, a combination of the difluoromethane and the tetrafluoroethane being at least 30% by weight to at most 60% by weight in the mixed working fluid,
wherein the polyol ester oil is a mixed lubricating oil which is a mixture of an oil additive and a base oil, a viscosity of the oil additive is adjusted to be equivalent to a viscosity of the base oil, and the oil additive is a mixture of:
a terpene type or a terpenoid type additive and a lubricating oil, an amount of the terpene type or the terpenoid type additive is equal to or greater than 1% and less than 50% of the mixed lubricating oil, and the lubricating oil has a higher viscosity than the viscosity of the base oil, or
the terpene type or the terpenoid type additive and the lubricating oil, the amount of the terpene type or the terpenoid type additive is equal to or greater than 1% and less than 50% of the mixed lubricating oil, the lubricating oil has a super-high viscosity, and an amount of the lubricating oil is equal to or greater than the amount of the terpene type or the terpenoid type additive.
