【課題を解決するための手段】
上記目的は、冷凍サイクル内に気液分離器を有し、この気液分離器から圧縮機の圧縮中間部にインジェクションを行う、冷房および暖房運転可能な空気調和機において、前記気液分離器は、縦長の円筒状の側壁部と、上壁部と、下壁部と、この側壁部内面と下壁部内面に接し気液分離器下部を第１空間部と第２空間部とに仕切る仕切板と、前記上壁部を貫通し前記第１空間部内にて前記下壁部に対向して開口する第１冷媒管と、前記上壁部を貫通し前記第２空間部内にて前記下壁部に対向して開口する第２冷媒管と、前記上壁部を貫通し上部にて前記下壁部に対向して開口する第３冷媒管とを備え、前記第１冷媒管の開口部から前記下壁内面までの距離と前記第２冷媒管の開口部から前記下壁内面までの距離を異なった距離に形成することにより達成される。 [0005]
[Means for Solving the Problems]
The above object is an air conditioner having a gas-liquid separator in a refrigeration cycle and performing injection from this gas-liquid separator to a compression intermediate portion of a compressor, wherein the air-liquid separator is capable of cooling and heating operation. A vertically long cylindrical side wall portion, an upper wall portion, a lower wall portion, and a partition which is in contact with the inner surface of the side wall portion and the inner surface of the lower wall portion to divide the lower portion of the gas-liquid separator into a first space portion and a second space portion A plate, a first refrigerant pipe passing through the upper wall and facing the lower wall in the first space, and passing through the upper wall and the lower wall in the second space And a third refrigerant pipe which penetrates the upper wall and is opposed to the lower wall at the upper part and is opened from the opening of the first refrigerant pipe. In forming the distance to the lower wall inner surface and the distance from the opening of the second refrigerant pipe to the lower wall inner surface at different distances Ri is achieved.

【０００６】
特に、前記第１冷媒管の開口部から前記下壁内面までの距離と前記第２冷媒管の開口部から前記下壁内面までの距離は、冷房運転と暖房運転のうち冷媒封入量が少ない運転時における、前記気液分離器内の冷媒流下流に位置する前記第１冷媒管若しくは前記第２冷媒管の先端開口部から前記下壁部内面までの距離が大きくなるように決めることにより達成される。 [0006]
In particular, the distance from the opening of the first refrigerant pipe to the inner surface of the lower wall and the distance from the opening of the second refrigerant pipe to the inner surface of the lower wall are the cooling operation and the heating operation among the cooling operation and the heating operation. This is achieved by increasing the distance from the tip opening of the first refrigerant pipe or the second refrigerant pipe located downstream of the refrigerant flow in the gas-liquid separator to the inner surface of the lower wall in time. Ru.

Claims

In an air conditioner capable of cooling and heating operation, having a gas-liquid separator in a refrigeration cycle and injecting from the gas-liquid separator to a compression intermediate portion of the compressor,
The gas-liquid separator is in contact with the longitudinally long cylindrical side wall, the upper wall, the lower wall, the inner surface of the side wall and the inner surface of the lower wall, and the lower part of the gas-liquid separator is a first space and a second A partition plate that divides into a space, a first refrigerant pipe that penetrates the upper wall and opens in the first space to face the lower wall, and penetrates the upper wall and the second space And a third refrigerant pipe which penetrates the upper wall and is open at the upper portion so as to face the lower wall. An air conditioner, wherein the distance from the opening of the refrigerant pipe to the inner surface of the lower wall and the distance from the opening of the second refrigerant pipe to the inner surface of the lower wall are different.

In Claim 1, the distance from the opening of the first refrigerant pipe to the inner surface of the lower wall and the distance from the opening of the second refrigerant pipe to the inner surface of the lower wall are the refrigerant charge amount in the cooling operation and the heating operation. Is determined such that the distance from the tip opening of the first refrigerant pipe or the second refrigerant pipe located downstream of the refrigerant flow in the gas-liquid separator to the inner surface of the lower wall section during operation with a small amount of Air conditioner.
