Abstract

The displacement volume of a compression mechanism (40) is defined as Vc [cc], the density of a refrigerant at 1.9 Mpa and 75°C as Dg [g/cm<3>], the number of revolutions of a rotary shaft (30) as N [rps], the volume of a primary space (S1) as V1 [cc], the volume of a secondary space (S2) as V2 [cc], the height of the primary space (S1) as H1 [cm], the height of the secondary space (S2) as H2 [cm], the density of refrigerating machine oil at 15°C as Do [g/cm<3>], and the solution viscosity of the refrigerating machine oil present at a level of a suction port (71a) or lower as η [mPa·S]. The rotary compressor satisfies relational expressions: N ≥ 100 [rps]; and ((8.19 × 10<-8> × Vc × Dg + 0.000327) × Vc<3.657> × N<3.126>)/(V1 × V2 × H1<1.867> × H2<1.556> × Do × η) ≤ 1.0. <img class="EMIRef" id="9bc56977-2269-4b63-9ad7-c8054ca75a0e-ia01" />
