The invention provides a liquid storage device, comprising a compressor device thereof and an air-conditioning system including the compressor device. Excess liquid refrigerant may be prevented from entering a compressor by decreasing flow equivalent diameter of a lower reflow hole, and by setting an upper flow hole with suitable flow equivalent diameter at a height above the lower reflow hole, when levels of the liquid refrigerant and frozen engine oil in the liquid storage device reach the upper reflow hole, the frozen engine oil flows into an exhaust pipe of the liquid storage device through the upper reflow hole and enters a compressor cylinder for oil reflow; the liquid storage device considers both liquid reflow and oil reflow, ingeniously solves the problems of excess liquid reflow and possible insufficiency of oil reflow and is applicable particularly to variable frequency air-conditioning systems.
Description
technical field [0001] The invention belongs to the field of air conditioning, and relates to a liquid accumulator, a compressor and an air conditioning system. Background technique [0002] In the compressor of the prior art, in the process of inhaling the refrigerant, the refrigerant more or less contains incompletely vaporized liquid refrigerant. In order to prevent liquid refrigerant from entering the compressor cylinder, a gas-liquid separator (also called a liquid receiver) for gas-liquid separation is installed at the intake pipe of the compressor to separate the incompletely vaporized liquid refrigerant and ensure that it enters the compressor. The refrigerant in the cylinder of the machine is dry steam. The liquid accumulator is generally arranged on one side of the hermetic housing of the compressor, and is directly and sealingly connected with the air inlet of the cylinder in the compressor assembly through a connecting pipe. [0003] However, after the compress...
