Abstract: Disclosed are a vapour-liquid filter mesh, a heat exchanger and an air conditioner. The vapour-liquid filter mesh includes a first area located in the middle and a second area located at the periphery of the first area, and the thickness of the second area is greater than the thickness of the first area.

Abstract: A refrigerant purification apparatus, comprising a main shell and a separation baffle, a liquid separation space and a liquid collection space located under the liquid separation space are formed in the main shell; the liquid separation space in communication with the liquid collection space by means of a collection pipe. The baffle is provided at a position adjacent to a first refrigerant inlet within the liquid separation space to collide with moisture-containing refrigerant injected by means of the first refrigerant inlet, such that the refrigerant and the water in the water-containing refrigerant are separated and layered in the liquid separation space; the pipe configured to introduce the refrigerant located at a lower layer in the liquid separation space into the liquid collection space; and a water outlet configured to discharge the moisture located at a upper layer in the liquid separation space.

Abstract: Some embodiments of the present disclosure provide an air conditioner oil separator, a condenser, and an air conditioner. The air conditioner oil separator includes: a gas inlet for introducing a refrigerant to be separated, a gas outlet for outputting a separated refrigerant, and a filter component disposed at the gas outlet. The filter component includes: a first filter area; a second filter area, which is closer to the gas inlet than the first filter area; and a third filter area, which is closer to the gas inlet than the second filter region. A separation efficiency of the first filter area for the refrigerant is lower than a separation efficiency of the second filter area for the refrigerant; and/or, a refrigerant separation efficiency of the third filter area for the refrigerant is lower than the separation efficiency of the second filter area for the refrigerant.
