Air Conditioning Air-Water Generator (AC-AWM)

General Description

The air-cooled, AC-AWM is operated off the ammonia absorption chiller coolant and brings to the market 4 varying sizes of Air Water Generators. Savings on energy can be significant as the AC-AWM is operating from the Absorber which is operated from free energy. Where the chiller is fired almost entirely by waste heat the AC-AWM requires only minimal power to run the fans dragging ambient air over the fins at varying speeds and depending on local atmospheric conditions. With the addition of the AC-AWM to a conventional CHP MultiGen set-up we can deliver tri-generation, or CCHP, allowing the simultaneous delivery of Electricity, cooling a space and water from the atmosphere in one system of true tri-generation.

In particularly dry RH climates, the additional Water Booster can be attached, doubling RH of the air to be treated, prior to moisture removal allowing greater water manufacturer in such conditions. This feature suits RH from 10%-45% RH. This feature is unique to this technology.

* Available for use 50Hz and 60Hz environments





Sizes and weight vary dependent on the system chosen i.e. 5,10,20 Ton system to be connected in series to the MultiGen Absorption chillers. Please ask for details.
