Abstract: A heat exchanger (10?) arranged to exchange energy with a flow (F) of air, said heat exchanger (10?) comprises a housing (11) arranged to receive said flow (F) of air through a first end (11a) and at least one conduit arrangement (12) arranged inside said housing (11) whereby said flow (F) of air will pass along the at least one conduit 5 arrangement (12) when said flow (F) of air is received by said housing (11), wherein the heat exchanger (10?) is arranged to be used in a a system where air is carrying particles, such as a marine environment, a kitchen system or a dryer system.

Abstract: A self-cleaning particulate separator unit (10) for use in a ventilation system is provided. The unit is configured to receive a flow of exhaust air containing pollutants, and the particulate separator unit (10) comprises at least one conduit (11) with an outer surface. The conduit (11) is configured to receive a refrigerant. The conduit is configured to have a first temperature and a second temperature. When the conduit has the first temperature condensation and a particle layer of pollutants is formed on the outer surface of the conduit (11), and when the conduit has the second temperature the condensation and the particle layer freezes and subsequently cracks such that the particle layer is detached from the conduit (11). Thus, self-cleaning is obtained.

Abstract: A ventilation system configured to be self-cleaning, wherein said ventilation system includes: a filtration unit configured to filter exhaust air led through it by at least one air duct; a condensation chamber configured to collect condensation water from the exhaust air; a heating element configured to heat the condensation water to a temperature equal to or above 65 degrees Celsius; and a sprinkler system configured to sprinkle the condensation water in one or more of the filtration unit, at least one of the at least one air duct, and/or the condensation chamber, wherein the ventilation system is thus configured to provide a self-cleaning of the ventilation system utilizing the condensation water.
