Temperature and humidity control methods, systems, and devices
Methods, systems, and devices provided in accordance with various embodiments are generally related to the field of thermal management systems for buildings (or volumes in general), such as cold storage, food processing, or other buildings that have areas that are kept below freezing. Embodiments generally pertain to the management of temperature and humidity within these spaces. Some embodiments include system for the management of moisture and temperature inside cold spaces. Some embodiments include a heat and mass transfer exchanger, such as a direct constant gas liquid heat and mass transfer exchanger. Examples of such heat and mass transfer exchangers generally include wet scrubbers. Embodiments also generally include a series of ducts, pipes, heat exchangers, dampers, and/or valves that may allow the system to provide useful temperature and relative humidity levels to one or more spaces or volumes.

7. The method of claim 6 , wherein passing at least the portion of the air from the first room in the facility through the recuperator increases the temperature of at least the portion of the air from the first volume after the air from the first room in the facility passes through the heat and mass transfer exchanger.
8. The method of claim 7 , further comprising combining the air from the first room in the facility with air from the second room in the facility prior to passing the air from the first room in the facility through the heat and mass transfer exchanger.
9. The method of claim 5 , wherein passing at least the portion of the air from the first room in the facility through the recuperator occurs after the air from the first room in the facility passes through the heat and mass transfer exchanger such that the temperature of at least the portion of the air from the first room in the facility increases through passing through the recuperator.
10. The method of claim 9 , further comprising combining the air from the first room in the facility with air from the second room in the facility prior to passing the air from the first room in the facility through the heat and mass transfer exchanger.
11. The method of claim 10 , further comprising positioning a blast freezer between the first room in the facility and the second room in the facility.
12. The method of claim 1 , further comprising combining the air from the first room in the facility with air from the second room in the facility prior to passing the air from the first room in the facility through the heat and mass transfer exchanger.
13. The method of claim 12 , further comprising combining ambient air with at least the air from the first room in the facility or the air from the second room in the facility prior to passing at least the air from the first room in the facility, the air from the second room in the facility, or the ambient air through the heat and mass transfer exchanger.
14. The method of claim 1 , further comprising:
removing air from the second room in the facility;
passing the air from the second room in the facility through the heat and mass transfer exchanger to decrease a temperature and a moisture content of the air from the second room in the facility; and
sending at least a portion of the air from the second room in the facility to the second room in the facility after passing the air from the first volume through the heat and mass transfer exchanger.
15. The method of claim 14 , further comprising at least passing the air from the second room in the facility through a recuperator before passing the air from the second room in the facility through the heat and mass transfer exchanger or passing at least the portion of the air from the second room in the facility through the recuperator after the air from the second room in the facility passes through the heat and mass transfer exchanger.
16. A method comprising:
removing air from a first volume;
passing the air from the first volume through a heat and mass transfer exchanger to decrease a temperature and a moisture content of the air from the first volume, wherein passing the air from the first volume through the heat and mass transfer exchanger to decrease the temperature and the moisture content of the air from the first volume includes passing the air from the first volume through a wet scrubber and wherein passing the air from the first volume through the wet scrubber includes flowing a brine counter to a flow of the air from the first volume and wherein a temperature of the brine is lower than a temperature of the air from the first volume;
passing at least a portion of the brine from the wet scrubber and at least the portion of the air from the first volume through a recuperator to decrease the temperature of the brine and to increase a temperature of at least the portion of the air from the first volume;
