Features / Benefits

16DNH offers a viable alternative to traditional electric driven chillers. Fired by natural gas or light oil, 16DNH reduces

costly electricity bills and qualifies for utility rebates and incentives as a gas cooling product. 16DN can operate in the

heating mode to provide hot water, thereby reducing the size of the required boiler or even eliminating the need for a

boiler.

Excellence Efficiency

COP=1.36 ( cooling water inlet temperature is 30°C)

High quality plate heat exchanger and tubes contribute to a high efficiency, more compact profile, lighter weight.

Uniquely designed flue gas heat exchanger fully recover exhaust heat, increase efficiency and decrease flue gas

temperature.

Environmentally Friendly Chiller

Using water and lithium bromide which are natural as refrigerant medium, no CFCs;

Fired by clean burning natural gas, light oil, few electricity cost.

Few moving parts enable quiet and vibration-free operation.

Superior Part Load Performance

Concentration control system allows stable, part-load operation at cooling water temperatures as low as 15°C ( 60.8 F )

without a cooling tower bypass.

For maximum efficiency, a VFD pump automatically maintains optimum solution flow rate at all operating conditions.

Continuous operating range from 100% to 25% capacity for gas-fired series and 100% to 30% for oil-fired series, based

on minimum fire requirements for the burner.

Reliable Operation

Microprocessor control center continuously monitors machine operation, ensuring precise control.

Superior corrosion protection.

Automatic, motorless purge system extends machine life and ensures optimum efficiency and performance.

Rugged machine construction.

Anti-crystallization controls maintain proper solution concentration.

Advanced Control System

Human friendly interface between chiller and user, all text strings for display and all alarm messages are provided in

several languages.

Excellent algorithms provide precise capacity control and optimize chiller operation.

Automatically calculates a solution concentration with cycle temperature and prevents a solution crystallization by

control the fuel input.

Having the ability to communicate with central control system and telecommunicate with telephone network.

Operation Cycle

Cooling cycle

Water is used as the refrigerant in evaporator maintained under low highly vacuum state. In the cooling mode, the chiller operates on the principle that under vacuum, water boils at a low temperature, thereby cooling chilled water.To make the cooling process continuous, refrigerant vapor must be removed as it is produced. A lithium bromide solution (which has a high affinity for water) is used to absorb refrigerant vapor. As this process continues, lithium bromide becomes diluted, reducing its absorption capacity. A solution pump then transfers this weak solution to the high temperature generator where it is heated and re-concentrated to a medium concentration solution by the heat from the combustion of fuel. The medium concentration solution flows to the low temperature generator where it is heated and re-concentrated to a strong solution by the high temperature water vapor released from the solution in high temperature generator.The water vapor released in the shell-side of low temperature generator, in addition to the condensed water vapor from the tube- side of low temperature generator, enters the condenser to be cooled and returned to a liquid state. The refrigerant water then returns to the evaporator to begin a new cycle.To remove heat from the machine, cooling water is first circulated through the tubes of the absorber to remove the heat of the evaporator. Then it is circulated through the tubes of condenser. The strong solution from the low-temperature generator flows back to the absorber to begin a new cycle.

Heating cycle

High temperature water vapor produced in the high temperature generator is passed directly to the evapora-tor via absorber where it condenses and transfers its heat to hot water circulating through the evaporator tubes. This condensed water then flows to the absorber where it mixes with the concentrated solution returning from the high temperature generator. The diluted solution is then pumped back to the high-temperature generator to repeat the vapor generation phase for the heating function.

1. Please refer to “Overall Dimension” & “ Physical Data” for pipe connection positions and sizes. 2. Positions of the equipment such as chilled (warm) water pump, cooling water pump, expansion tank, etc. shall take account of water level difference and static pressure to ensure the gauge pressure of the unit does not exceed 1.0MPa (it is the non-standard model if water pressure is greater than 1.0MPa). 3. Each unit shall be configured with relevant special chilled water pump, cooling water pump and cooling tower. Meanwhile, each unit shall be connected to other units so that they can serve as standby for each other. 4. (8～10 meshes) filter shall be installed in front of the inlet of chilled water and cooling water system tube of the unit. 5. Pressure gauge (0～1.5MPa) and thermometer (0～100°C) shall be set at the inlet/outlet of the chilled water and cooling water of the unit. 6. Air vent valve shall be set at the position where chilled water and cooling water system pipe higher than each water chamber, and drain valve shall be set the bottom of the inlet pipe of chilled water and cooling water. 7. Air vent (R3/4”) shall be set at the top of the water chamber of evaporator and absorber of the unit. 8. Drainage outlet (R3/4”) shall be set at the bottom of the water chamber of evaporator and absorber of the unit, where pipe to the drainage ditch shall be installed.9. If cooling water inlet temperature tends to decrease to below 15°C, a bypass valve shall be installed at the place indicated with dashed line in the figure to maintain cooling water temperature not lower than 15°C.10. Please set water flow adjusting valve at the inlet pipe of cooling water.11. Please provide support for piping. All pipes shall carry no load.12. While the unit stops during heat supply operation in winter, it must guarantee that the water in the unit and pipes can be drained completely to prevent from frost damage to the pipe.13. During heat supply operation of the unit, outer wall temperature of the pipes connected to the absorber may reach over 80°C. High temperature resistant material shall be used for thermal insulation for a section of cooling water pipe close to the absorber. 14. Connecting hose shall be set at the connecting part of the unit and each pipe. 15. Water pressure detection for chilled water and cooling water system must be carried out in accordance with relevant standard. It is strictly forbidden to adopt air pressure detection. 16. It would be better to set expansion tank on chilled water system. 17. To measure flow in chilled water pipe, it is recommended to set flowmeter on the pipe. 18. Please refer to relevant contents for chilled water and cooling water quality control to decide whether water treatment equipment should be set or not. 19. Cooling tower should be set at well-ventilated place, in the upwind direction of smoke, dust, etc.. 20. Machine room environment: poor ventilation may cause the machine room to become humid, which may corrode machine. Too high temperature may damage electric components of the unit, while too low temperature may lead to frost crack of copper tube. Temperature in machine room shall be controlled within 5～40°C, and humidity shall be controlled below 95%.

Hoisting & Shipping

Hoisting & Shipping

An absorbing pad should be placed below the support of the unit to reduce vibration during the shipment. Transport personnel should decelerate when driving on bumpy road to prevent unit from damage due to intense vibration. Note: (1)Please hoist the unit carefully. Ensure no part will be damaged. If lifting rope contacts wearing part, length of lifting rope shall be adjusted to avoid contacting wearing part. (2)When lifting down the unit, please keep the horizontality of the unit. Ensure base frame of the unit contacts ground simultaneously. (3)Bed plate only serves as an anti-vibration tool, instead of standard component part of the unit; When the unit is installed in place, bed plate shall be removed.

Placement

(1)Before the installation, confirm that concrete foundation has enough hardness. (2)After the installation, adjust the longitudinal and horizontal level of the unit based on level benchmark point of the tube plate of the unit. Adjusted level error shall be less than 1/1000. (3)After level adjustment is completed, pour concrete mortar into square foundation bolt holes, and tighten founda-tion bolts used to fix the unit after concrete mortar is hardened.
