1 Absorption Chillers TGG, TBG, TEG, TUG, 3.9 TBS, Gene-Link series Stable Chilled Water Outlet Temperature PID control is applied to maintain constant chilled water outlet temperature. When the cooling load changes, the chiller adjusts the amount of heat used to regenerate the desiccant. Temperature control is +/- 1.0ᵒC. Automatic De-crystallization System To 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 Temperature Setpoints can be changed from the HMI on the chiller or remotely through LonWorks communication. High Airtight Structure The 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 have been 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 Dual fuel combustion - switching from oil to natural gas Marine waterboxes Large temperature difference to reduce the powe of auxiliary pumps Inverter control for solution pumps LonWorks for BAS Remote control Scope of Supply Item LiBr Solution & Refrigerant Water Thermal Insulation Spare Parts Auxiliary Equipment (Pumps, Cooling Tower) Piping Work Electric Power & Primary Interlock Wiring Start-up and Commissioning at Job Site Utilities Required for Commissioning PPI Factory Provided Factory - required Factory - optional Factory - required Provided Notes For larger machines, LiBr will ship separately.

2 Gene-Link Hybrid Hot Water + Direct Fired Sigma Ace TBJ, TUJ series Hybrid Double Effect Direct Fired w/ Waste Heat Hot Water Energy Recovery for Maximum Energy Savings. No Gas Firing Required at Partial Load Hot water provides the first stage of cooling. Direct firing boosts the output as required at high efficiency. Seamless transition to/from hot water consumption and back to double effect gas firing. Perfect for Solar Thermal and Tri-Generation (CCHP). Also operates as a water heater in winter at 85% efficiency. Fuel Gas Consumption Rate (BTU / Full Load Ton) Higher Waste Heat Rate at Partial Load Designed for maximum hot water utilization As load increases, LiBr solution temperature must increase. Minimizes solar thermal costs - maximizes return. No need for secondary boiler for solar backup or wintertime. Inverter controlled pumps included as standard. Waste Heat Recovery Rate Standard Mode - All Gas Hybrid Mode With Waste Hot Water 100% Savings at Part Load Free cooling up to 57% load 0% 20.0% 40.0% 60.0% 80.0% 100.0% Cooling Load (% of Nominal Tonnage) 38% Savings at Peak Waste Heat BTU's Used per Full Load Ton Free Cooling from Waste Hot Water 0% 20.0% 40.0% 60.0% 80.0% 100.0% Cooling Load (% of Nominal Tonnage) Gas Firing Note Waste heat hot water temperature 90ᵒC (194ᵒF) Note The waste heat recovery rate is greater during partial load because the LiBr solution temperature must increase during full load operation. Less heat can be recovered at higher temperatures.

8 Piping Procedure Direct Fired Gene-Link Steam Absorption The 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 operating pressure 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 during the heating mode.

9 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.
