  1. 1
    41 CLAIMS 1. Device for removing moisture and/or another substance from ambient air or from a gas, the device being configured to operate alternately in an adsorption phase and a desorption phase, the device comprising:- a vessel comprising an entry and an exit which comprise valves allowing the exit and entry to be opened and closed;- a body of adsorption material positioned inside the vessel dividing the inside of the vessel in an upstream region and a downstream region;- a fan arranged in the vessel for blowing air or gas through the body of adsorption material from the upstream region to the downstream region;- a heating element arranged in the vessel for heating the air or gas inside the device;- a condenser loop, the condenser loop comprising: - a condenser located outside the vessel, - a branch conduit which extends from the vessel to the condenser and which allows a branch flow of air or gas to flow from the downstream region to the condenser, and - a condenser return conduit which extends from the condenser to the vessel and which allows the branch flow to return from the condenser to the upstream region of the vessel;wherein the device further comprises: - at least one main return conduit for returning a main return flow of air or gas from the downstream region to the upstream region while bypassing the condenser.
  2. 5
    Device according to any of claims 1, wherein - the body has a substantially tubular shape.
  3. 14
    Method of removing moisture or another substance from ambient air or from a gas, in particular an exhaust gas, the method comprising:- providing a device comprising - a vessel having positioned therein a body of adsorption material, said vessel further having an entry and an exit;and - a condenser;- operating said device alternately in an adsorption phase and a desorption phase, wherein - during the adsorption phase: - feeding ambient air or gas into the entry and through the body of adsorption material;- adsorbing moisture and/or another substance from the air or gas by the adsorption material;and - discharging the air or gas through the exit, - when the adsorption material is saturated, switching to the desorption phase, and - during the desorption phase: - closing the entry and the exit, - repeatedly circulating the air or gas through the body of adsorption material in a main loop of repeated flow bypassing the condenser while heating the air or gas, thereby desorbing the one or more substances from the adsorption material, and - while circulating the air or gas through the body of adsorption material in a main loop of repeated flow bypassing the condenser, circulating a portion of the air or gas from the vessel through a condenser located outside the vessel for removing moisture and returning the dried air or gas into the vessel after the condensation.
  4. 19
    System for cooling air, heating air, desalination of water and/or water purification, the system comprising:- two devices according to the claim 1 as a dehumidifier, wherein the devices are configured to operate alternately in adsorption mode and desorption mode.
  5. 30
    Evaporative air cooling device comprising:- a first, regenerative indirect evaporative air cooler comprising: - a primary air channel for conveying a primary air flow between a primary air inlet and a primary air outlet, - a regenerative air channel which is fed with a regenerative air flow to be used as a coolant, wherein the regenerative air channel is branched off from the primary air channel at a branch off point, - an evaporative water distribution system for distributing an evaporative water in the regenerative air channel for cooling the regenerative air flow, 48 - a heat exchange surface placed between the primary air channel and the regenerative air channel for conducting heat from the primary air flow to the regenerative air flow, - a second, direct evaporative air cooler, the direct evaporative air cooler device being arranged downstream from the indirect evaporative air cooler and coupled to the primary air outlet 5 of the indirect evaporative air cooler, - a third, auxiliary air cooler for cooling the regenerative air flow with an auxiliary air flow, wherein the third, auxiliary air cooler comprises: - an auxiliary air inlet for the auxiliary air flow, an auxiliary air channel, and an auxiliary air outlet for the auxiliary air flow, 10 - an auxiliary evaporative water distribution system for distributing an evaporative water in the auxiliary air channel for cooling the auxiliary air flow, - a heat exchange surface placed between the auxiliary air channel and the regenerative air channel for conducting heat from the regenerative air flow to the auxiliary air flow. 15 Dr. Mark Friedman LTD.
