レータに関する。The present invention relates to an accumulator for a two-cylinder rotary inverter compressor.

As shown in FIG. 2, a two-cylinder rotary inverter compressor incorporating a system intake and two cylinders 3a and 3b separated by a motor 2 and an intermediate partition plate 3c inside a closed case 1 as shown in FIG. And the accumulator 4 is disposed close to the outside of the closed case 1.

されている。Each of the suction ports 5 of the two cylinders 3a and 3b communicates with the inside of the accumulator 4 via two suction pipes 6, and the two suction pipes 6 are connected to the two suction ports 5 respectively by two curved pipe sections. 7 are connected, and the two curved pipe sections 7 extend into the accumulator 4 as two straight pipe sections 8.
アキュムレータ４は取付用金具（図示せず）を用いて
密閉ケース１に取り付けられている。The accumulator 4 is attached to the closed case 1 by using a fitting (not shown).
（ハ）発明が解決しようとする課題 吸入管の長さと回転式圧縮機の性能との関係について
は、既に、単気筒回転式圧縮機にて冷媒流量は吸入管長
が一次共振長さに近いところで最大となることが知られ
ており、その一次共振長さは次式で表わされる。(C) Problems to be Solved by the Invention Regarding the relationship between the length of the suction pipe and the performance of the rotary compressor, the flow rate of the refrigerant in a single-cylinder rotary compressor has already been measured when the suction pipe length is close to the primary resonance length. It is known to be maximum, and its primary resonance length is expressed by the following equation.
ｌ＝λc/2πｆ ……（１） l:一次共振長さ λ：π/2 c:音速 f:周波数 ところが、冷媒流量が最大となる吸入管長は（１）式
に示すように周波数ｆに反比例するため、周波数ｆの低
い領域では下シリンダ3bの吸入量が大となるように、
又、循環量が増える高周波数領域では吐出抵抗の少ない
上シリンダ3aの吸入量が大となるように、上シリンダ3a
の吸入管長を短くするとともに下シリンダ3bの吸入管長
を長くするのが望ましいという問題があった。l = λc / 2πf (1) l: primary resonance length λ: π / 2 c: sound velocity f: frequency However, the suction pipe length at which the refrigerant flow rate is maximum is inversely proportional to the frequency f as shown in equation (1). Therefore, in a region where the frequency f is low, the suction amount of the lower cylinder 3b is large,
Also, in the high frequency region where the circulation amount increases, the upper cylinder 3a has a lower suction resistance so that the suction amount of the upper cylinder 3a having a smaller discharge resistance is larger.
However, there is a problem that it is desirable to shorten the suction pipe length of the lower cylinder 3b and increase the suction pipe length of the lower cylinder 3b.
その場合上シリンダに連なるアキュムレータは密閉ケ
ースに設置されるが、下シリンダに連なるアキュムレー
タはユニットサイドに設置されることになる。In that case, the accumulator connected to the upper cylinder is installed in the closed case, but the accumulator connected to the lower cylinder is installed on the unit side.
