An oil separator to separate oil from oil and refrigerant mixture. The oil separator includes inlets to allow entry of the oil and refrigerant mixture into the oil separator. The mixture flows and strikes on center of the one or more walls of the oil separator. The mixture then flows towards demister pads for filtration. The oil is separated from the mixture and exits the oil separator from the oil outlet. The refrigerant separated from the mixture escapes through the refrigerant outlet.

A multi-mechanism wet dust removal apparatus that circulates water and removes ambient dust, and a dust removal method. The multi-mechanism wet dust removal apparatus includes a dust collecting device, a dust settling and air-water separation device, a water circulating device, and a dust discharging device. The dust removal is achieved by dust collecting, dust settling, air-water separation and dust discharging. Water can be recycled and the dust removal method integrates multiple dust removal mechanisms.

An apparatus for removing moisture from exhaust gas is disclosed. The apparatus includes an inner chamber including an inner exhaust port, configured to discharge the exhaust gas flowing along a chimney, and an outer chamber, surrounding the inner chamber and including an outer exhaust port configured to discharge the exhaust gas discharged from the inner exhaust port, wherein an exhaust path is defined between the inner chamber and the outer chamber such that the exhaust gas discharged from the inner exhaust port flows along the exhaust path and is discharged through the outer exhaust port.

A system to collect liquid includes a wavy surface formed on a substrate, where the wavy surface includes a plurality of waves. The plurality of waves are configured to capture liquid from the air such that the liquid accumulates in valleys of the waves. The system also includes a liquid collection container configured to collect the liquid captured on the plurality of waves.

There is provided a breather chamber structure. An inner wall partitions a breather space surrounded by outer walls into a plurality of chambers including a first chamber, a second chamber, and a third chamber. An inlet allows the gas to flow into the first chamber. A first communication path communicates between the first chamber and the second chamber. A second communication path communicates between the second chamber and the third chamber. An outlet allows the gas in the third chamber to flow out of the breather space. An oil discharge port is configured to return oil separated from gas in the breather space to an oil reservoir. The third chamber has a volume equal to or greater than half of a volume of the breather space. The first chamber has a volume larger than a volume of any of the chambers except for the first and third chambers.

Disclosed is a desorber (20) for an air conditioning system with an integrated microemulsion-based air dehumidification system, the desorber having: a desorbing sheet that is wound to form an exterior end (21), an interior end (22), a top end and bottom end, wherein a collection tube (23) is disposed at the interior end and the desorbing sheet has: a plurality of de-entrainment mesh layers extending between the exterior end and the interior end of the desorbing sheet, and a plurality of substantially air impermeable connector layers extending between the exterior end and the interior end of the desorbing sheet, wherein the connector layers are interlaid with the mesh layers between the top end and the bottom end of the desorbing sheet.

A particle separator includes a housing through which a flow stream is directed. A number of guide vanes are disposed in the housing. The guide vanes have a profile wherein the flow stream is guided to follow the profile. The guide vanes have a wall surrounding an open interior that defines a vane plenum. A plurality of through-holes extend through the wall of the guide vane. The through-holes are open to the flow stream and to the vane plenum. A duct connects with the vane plenum and is configured to discharge particles collected in the vane plenum.

An intake system for an internal combustion engine may include an air inlet; a forced induction device downstream from the air inlet; an intercooler downstream from the forced induction device; and an intake conduit configured to guide air from the intercooler to an internal combustion engine. In addition, the system may include a condensate retaining structure associated with the intake conduit and configured to restrict the flow of condensate through the intake conduit.
