Gas-liquid separator and air conditioner

Abstract

The invention provides a gas-liquid separator and an air conditioner. The gas-liquid separator comprises a shell and at least one separation tank arranged in the shell, an outer containing cavity is formed between the separation tank and the shell, and an inner containing cavity is formed in the separation tank; and an air outlet pipe communicates with the exterior of the inner containing cavity and the exterior of the shell, air inlet pipe is arranged below the air outlet pipe and communicates with the exterior of the inner cavity and the exterior of the shell, and an outlet communicating with the outer containing cavity is formed in the lower portion of the inner containing cavity. The gas-liquid separator provided by the invention is provided with an inner cavity and an outer cavity, and the exhaust rate is increased and the re-dissolution of gas and liquid is reduced by utilizing the relatively compact space and the relatively short gas outlet distance of the inner cavity; the inner cavity is divided into an upper separation chamber and a lower separation chamber through a gas-liquid separation plate, gas entering the lower separation chamber from the air inlet is subjected to primary separation and then upwards enters the upper separation chamber through the gas-liquid separation plate, and in the process, secondary gas-liquid separation can be achieved, re-dissolution is further reduced, and the separation efficiency is improved; and a plurality of separation tanks which are connected in series can be arranged to realize a multi-stage separation effect, so that the gas-liquid separation is more thorough.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning gas-liquid separators, and more specifically relates to a gas-liquid separator with high separation efficiency and an air conditioner using the same. Background technique [0002] At present, in the large-capacity refrigeration systems on the market, such as air conditioners, due to the large amount of refrigerant, in some abnormal working conditions such as low-temperature heating, the compressor of the air conditioner after inhaling air has a liquid state. Refrigerant and lubricating oil mixture, so it is prone to liquid hammering, which will cause the compressor to start frequently with liquid, and long-term operation will cause damage to the compressor. In addition, due to the presence of liquid refrigerant in the suction air of the compressor under certain abnormal working conditions, when the gas carrying the liquid refrigerant enters the compressor, the lubricating oil in the compr...
