  • Publication number: 20240167708
    Abstract: The present invention relates to a computer implemented method for controlling temperature and humidity of an air in stream, the method comprising receiving parameters indicative of a temperature and water content of an airstream in a downstream M section and of a temperature and water content of a medium in the system, and further determining in processing circuitry a desired temperature change and desired water content change of the first medium as a first function f1 based on the received parameters and also based on a second function that defines a relationship between the air temperature and the air water content as co-dependent variables; and also generating a first and second control signal configured to apply the desired temperature change and the desired water content change to the first medium. The invention also relates to a corresponding system.

  • Publication number: 20210199318
    Abstract: An air treatment unit (100) arranged for an intake of a first flow (110) of air into a space (120) in communication with the air treatment unit, and arranged for a discharge of a second flow (130) of air from the space. The air treatment unit comprises a heat-exchanging unit (140) arranged for thermal exchange between the second flow of air and the first flow of air, and a catalyst (150) configured to capture at least one impurity of the first flow of air. The catalyst is provided on at least a portion (160) of the heat-exchanging unit arranged to come into contact with the first flow of air during operation of the air treatment unit.

  • Patent number: 10941952
    Abstract: The present specification relates to a system for managing the condition of air in an enclosed environment comprising a flow path adapted to circulate a flow of air through the enclosed environment, the flow of air comprising at least one of a first portion comprising a gas comprising oxygen and a second portion comprising indoor air from the enclosed environment. The flow path selectively provides the portions. An air processing assembly is adapted to receive the flow of air. A first and a second air processing element is provided. A control system is adapted to determine the first portion of gas comprising oxygen and the second portion of indoor air from the enclosed environment and control the selectively coupling of the air processing elements to the flow path.
