HORIZONTAL GAS-LIQUID SEPARATOR FOR AIR CONDITIONER, AND AIR CONDITIONER
FIG9 is a sectional view of a horizontal gas-liquid separator for an air conditioner according to an embodiment of the present invention 
According to some embodiments of the present invention, as illustrated in FIG9, the end of the refrigerant inlet pipe 120 has an elbow section, and the elbow section is gradually bent downwards in a direction from a fixed end of the elbow section to a free end of the elbow section. Thus, the gaseous refrigerant entrained with liquid refrigerant component can be further prevented from directly flowing out through the gas outlet 111 after the gas-liquid mixed refrigerant enters the cavity 110, which results in a phenomenon of poor gas-liquid separation effect. In some embodiments of the present invention, as illustrated in FIG9, the out end of the refrigerant inlet pipe 120 has a bent section, and the bent section is connected to a straight pipe section in a smooth transition. Thus, after entering the cavity 110, the gas-liquid refrigerant can flow to the right sidewall of the cavity 110 in a lower-right direction (left and right directions as shown in FIG9) and turns back, so as to increase the gas-liquid separation stroke, and improve gas-liquid separation effect.
