A building hybrid air conditioning system having a conventional refrigeration subsystem in combination with a liquid desiccant dehumidification subsystem that dehumidifies make-up ventilation air is provided with an additional and localized dehumidifier assembly that cooperates with the dehumidification subsystem liquid desiccant central supply to remove excess moisture from its localized zone in by-pass relation to system dehumidification of the make-up ventilation air.

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, comprising: a.) a plurality of 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 said system base latent heat load; b.) a refrigeration sub-system handling said system base sensible heat load and effecting temperature changes in recirculated air distributed to said separate building occupancy zones; c.) a first dehumidification subsystem handling said system base and additional intermittent local latent heat loads, effecting moisture content changes in recirculated air distributed to said separate building occupancy zones, and comprising a first desiccant dehumidifier unit, a first concentrated desiccant solution supply cooperating with said first desiccant dehumidifier unit, and a first dilute desiccant solution regenerator cooperating with said first desiccant dehumidifier unit and with said first concentrated desiccant solution supply; and d.) a second desiccant dehumidification subsystem comprising a second desiccant dehumidifier unit located within said one building occupancy zone, a second concentrated desiccant solution supply cooperating with said second desiccant dehumidifier unit, and means recirculating air within said one building occupancy zone in mass-transfer relation to said second desiccant dehumidifier unit to effect moisture content changed in air recirculated within said one building occupancy zone by said air recirculating means, said second desiccant dehumidification subsystem transferring moisture from said second desiccant dehumidifier unit for subsequent removal from the building through said first desiccant dehumidification subsystem dehumidifier unit and connected dilute desiccant solution regenerator.
