Patent ID: 7886557

Claim:
A water producing device configured to remove moisture from the air to for potable water and provide additives thereto, the water producing device comprising: a) a refrigeration cycle comprising: a water condensation member in thermal communication with the operating fluid that is adapted to transfer heat from the operating fluid, an expander downstream of the condenser coil and upstream from the water condensation member, a compressor interposed in a fluid circuit between an evaporator coil and a condenser coil, b) the water condensation member positioned above a collection tray, the water collection tray having a conduit for communication with a main tank adapted to have water contained therein, c) an additive depositor configured to insert additives to water collected from the water condensation member, d) an additive control system comprising an additive water content sensor configured to measure the content of dissolved additives of the water in the main tank, the additive control system configured to circulate the water through the additive depositor when the content of additives in the water content sensor detects an additive content in the water that is below a prescribed additive content level of the additive control system.
