The patented Reverse Cycle design provides the world's Save even more fuel when optional Inverter Control for thehighest efficiency. Solution Pump is applied.Fuel gas consumption can be reduced as follows compared to conventional models: TBG series: 9%

TEG series: 15%TUG series: 22%

Note Note

1. The standard calorific value of gas applied above is HHV=1237 BTU/scf. 1. 1.4 Series and 1.2R Series are equipped with inverter control as standard.

2. The capacity of the chiller in the above simulation is 210 USRT. 2. It is assumed that cooling water inlet temp is 89.6ᵒF at 100% load, 80.6ᵒF at

0% load and it varies proportionally while the load is changing.

3. The above graph shows plotted points of maximum COP and the actual

measured value may vary depending on site conditions.

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.
