Localized air dehumidification system
This patent describes a building air-conditioning system for effecting air temperature and moisture content changes in air distributed to, flowed through, and recirculated from multiple separate building occupancy zones. It comprises separate building occupancy zones which together source a system base sensible heat load and a system base latent heat load, and which has at least one building occupancy zone which sources a system intermittent local latent heat load which is in addition to the system base latent heat load; a refrigeration sub-system handling the system base sensible heat load and effecting temperature changes in recirculated air distributed to the separate building occupancy zones; a first dehumidification subsystem handling the system base and additional intermittent local latent heat loads, effecting moisture content changes in recirculated air distributed to the separate building occupancy zones, and comprising a first desiccant dehumidifier unit; a second desiccant dehumidification subsystem comprising a second desiccant dehumidifier unit located within the one building occupancy zone, a second concentrated desiccant solution supply cooperating with the second desiccant dehumidifier unit.
