Absorption Chillers

TGG, TBG, TEG, TUG, 3.9 TBS, Gene-Link series

Stable Chilled Water Outlet TemperaturePID control is applied to maintain constant chilled water outlet temperature. When the cooling load changes, the chiller adjuststhe amount of heat used to regenerate the desiccant. Temperature control is +/- 1.0ᵒC.

Automatic De-crystallization SystemTo prevent crystallization, the concentration of the LiBr solution is controlled by adjusting the heat input. The chiller monitors the temperature of Chilled Water, Cooling Water,and Solution for this purpose.If the Cooling Water temperature decreases or the load decreases, the chiller will automatically decrease the heat input to prevent crystallization.

Easy Setting of Chilled Water Outlet TemperatureSetpoints can be changed from the HMI on the chiller or remotely through LonWorks communication.

High Airtight StructureThe body of the chiller is robotically welded and checked for leaks by filling with helium in a controlled space. No sight glasses and the minimum number of valves and screws havebeen used to achieve maximum airtightness. This prolongs the life of the chiller and decreases the maintenance.

Standard Features:Automatic restart in case of a power failure Maximum operating pressure of 784 kPa (114 psi)No requirement for operation of Chilled/Cooling Water Pump during the diluting operation of the desiccant.

Optional Items:Oil fired combustion Inverter control for solution pumpsDual fuel combustion - switching from oil to natural gas LonWorks for BASMarine waterboxes Remote controlLarge temperature difference to reduce the powe of auxiliary pumps

Piping Procedure

Direct Fired Gene-Link

Steam AbsorptionThe Stop valve shall be installed in the Inlet/Outlet piping for Chilled/Hot Water,

Cooling Water, and Waste Heat Hot Water.Pressure gauges and thermometers shall be installed near Inlet/Outlet piping for both

Chilled/Hot Water and Cooling Water.The flow rates shall be controlled to be stable. If the Chilled/Hot Water Flow Rate

drops suddenly, the chiller may stop for safety reasons.The positions of the pumps and expansion tanks shall be designed taking into

consideration their pump head, static water head, and the maximum operatingpressure of the Chiller.

Do not exceed the maximum operating pressure of the chiller.Install the air vent valve in the appropriate place for all water circuits. Pipe to drain pit.Waterboxes contain drain valves for service. Allow for access and drain to floor.Two stop valves shall be installed for chemical cleaning of the Cooling Water System.Necessary measures shall be taken to avoid freezing of water in the piping and inside the

Chiller during non-operationg of the Chiller in winer.The piping shall be removable for service. See Detail A.If the Chiller is installed at the same level as the Cooling Tower, it is required to take

measues to prevent reverse flow drainage during non-operation.The necessary measures shall be taken to avoid the combustion exhaust gas from entering

the Cooling Tower or fresh air intake.Heat resistant piping shall be installed for the Cooling Water System if the Chiller is also

used for heating. The Cooling Water temperature may go up to approx. 90ᵒC duringthe heating mode.

Cooling Water Control

1. Take care so that the cooling water inlet temperature is above 22ᵒC.2. Install blow-down valve in the cooling water piping before the cooling tower to prevent excess concentration of contaminants in the cooling water.3. Clean the cooling tower periodically to reduce biological growth that will reduce performance and shorten equipment life.4. Cooling water control shall be done in accordance with the guideline of JRA (JRA-GL-02=1994) or in consultation with specialized water treatment chemical dealer.
