1. A liquid reservoir for a refrigeration system, comprising:
a drum body, a gas-liquid separation chamber being defined therein; and
an air intake pipe, used for connecting to an evaporating pipe of an evaporator of the refrigeration system, and extending into the gas-liquid separation chamber from one end of the drum body, the end of the air intake pipe extending into the gas-liquid separation chamber being provided with a baffle opposite to a mouth of the air intake pipe, so that a mixture discharged from the air intake pipe hits the baffle and then is discharged into the gas-liquid separation chamber from an interval between the baffle and the air intake pipe,
wherein the pipe diameter of the part of the air intake pipe extending into the gas-liquid separation chamber gradually shrinks from the section of the air intake pipe in contact with the drum body to the end of the air intake pipe provided with the baffle with the increase of an extending length.
