The Carrier Corporation has more than 100 years experiencein providing HVAC systems and equipment around the world.Sanyo is a leading manufacturer in the field of high-efficiency absorption chillers. Carrier-Sanyo absorptionchillers, produced by Sanyo for Carrier, provide a uniquechoice of models for all absorption chiller applications.
Features■ The Carrier-Sanyo 16TJ single-effect absorption chillers are
designed for cooling applications where low-pressure steamis available as waste heat.
■ They can tie into district steam systems.■ Carrier-Sanyo absorption chillers allow diversification of
critical cooling requirements. Critical cooling loads are metwith minimal electrical power input.

■ They allow smaller emergency generators compared to anelectrical driven chiller.
■ The units are ozone-safe and CFC-free. Cooling require-ments are met without chlorine-based refrigerants.
■ They reduce the contribution to global warming andminimize the global impact by greatly reducing electricityconsumption and production of greenhouse gases.
■ The solution inhibitor has no impact on the environment.■ An absorption chiller does not utilize a large motor-
compressor, and this leads to quiet, vibration-free operation.■ The use of high-efficiency heat transfer surfaces has reduced
the space required for installation of the absorption chiller,resulting in a smaller footprint.
Carrier-Sanyo is the industry leader in compact absorptionunits.

Figure 1 - Simplified absorption cycle
The absorption cycleThe absorption cooling cycle, like the mechanical vapourcompression refrigeration cycle, utilizes the latent heat ofevaporation of a refrigerant to remove heat from the enteringchilled water. Vapour compression refrigeration systems use achlorine-based refrigerant and a compressor to transport therefrigerant vapour to be condensed in the condenser. Theabsorption cycle, however, uses water as the refrigerant andan absorbent lithium bromide solution to absorb thevaporized refrigerant. Heat is then applied to the solution torelease the refrigerant vapour from the absorbent. Therefrigerant vapour is then condensed in the condenser.The basic single-effect absorption cycle (see Figure 1)
includes generator, condenser, evaporator and absorber withrefrigerant (liquid) and lithium bromide as the workingsolutions. The generator utilizes a heat source (burner, steamor hot water) to vaporize the diluted lithium bromide solution.The water vapour that is released travels to the condenserwhere it is condensed back into a liquid, transferring the heatto the cooling tower water. Once condensed, the liquidrefrigerant is distributed over the evaporator tubes, removingthe heat from the chilled water and vaporizing the liquidrefrigerant. The concentrated lithium bromide solution fromthe generator passes into the absorber, absorbs the refrigerantvapour solution from the evaporator and dilutes itself. Thediluted lithium bromide solution is then pumped back to thegenerator where the cycle is started again.

Carrier-Sanyo control system■ The Carrier-Sanyo control system surpasses other
proportional only control systems available today. The digitalPID (proportional plus integral plus derivative) controlmaximizes unit performance by maintaining a ±0.5 Kvariance in leaving chilled-water temperature from thesetpoint. Proportional controls can typically only maintain a±1 K variance from the setpoint. The controller’s innovativedesign also incorporates the ability to start and stop thesystem chilled/hot and cooling water pumps. Duringshutdown these pumps are sequenced to ensure a completedilution cycle.
■ The leaving chilled-water temperature is measured every fiveseconds and steam input is changed according to the gradientof the leaving chilled-water temperature curve. Systemtemperatures, setpoints, and operational records are displayedalong with indicator lights for the chiller and pumps.
■ The Carrier-Sanyo control system offers its users self-diagnostics by constantly monitoring the chiller status andwill automatically shut the chiller down should a fault occur.The cause of shutdown will be retained in the memory andcan be displayed for immediate operator review. Thecontroller’s memory will also retain and display the cause ofthe last three system fault conditions. This method ofretaining fault conditions is extremely useful for maintainingan accurate record of unit performance and fault history.

Fast digital PID control■ The introduction of new digital PID control to the J-model
stabilizes the chilled/hot-water temperature with higheraccuracy than the previous E-model. It quickly responds tothe load fluctuation and supplies stable chilled/hot-watertemperature. It is suitable for air-conditioning intelligentbuildings which require sophisticated control.
Saving energy with the inverter (option)■ Balancing the load and flow rate with the absorbent pump’s
inverter control enables efficient and energy-saving operation.As a result, it reduces input energy and electric powerconsumption. Running cost is decreased by 5% compared tonon-inverter control.

Purge system■ The high-performance purge system maintains the required
operating pressure, preserves chiller performancecharacteristics, minimizes chiller maintenance to one purgeoperation per season (for year-round operation).
Steam valve opening control■ At the start-up the opening angle of the steam control valve is
controlled in three stages, reducing the amount of steam andthe time needed to reach the desired level, compared with theprevious model.
■ Adjusting the opening speed of the steam control valve at thesecond and third stage, it is possible to set up the mostsuitable conditions for the site auxiliary equipment.

General remarks on piping1. Work outside the area surrounded by this line shall be
undertaken at the expense of the owner.2. For pipe connections and diameters refer to the dimensional
drawings and specification tables.3. Steam pressure at the inlet of the machine cannot exceed 146
kPa. Please refer to the diagram to install a pressure reliefvalve near the chiller to release pressure above 146 kPa. Therelief valve should be piped to the outdoors.
4. Even if a reducing valve is not required, a strainer, pressuregauge and drain trap should be provided for each machinenear the steam inlet.
5. The back pressure of the steam drain outlet pipe should becontrolled below 19.6 kPa.
6. Determine the location of the chilled and cooling waterpumps with due consideration of the pump’s hydrostatic head.The machine should not be subject to a pressure larger than1034 kPa at any water headers.
7. Cooling water minimum entering control has to be supplied(please refer to the Installation Manual).
8. Provide a thermometer and a pressure gauge at the coolingwater and chilled water outlet and inlet.
9. Provide an air vent valve in each of the chilled and coolingwater lines at a point higher than the header for chilled waterand cooling water.
10. Drain pipes from the evaporator and absorber should be pipedto the drain channel.
11. Provide a blow-down valve in the cooling water line for waterquality control.
12. All external water piping is to be designed for maximum unitwater-side pressure (to cover any options used).
13. Be sure to provide a shutoff valve to prevent steam flow intothe chiller during shut-down.In case two or more chillers are installed, provide anautomatic shutoff valve.
14. Be sure to design the location of the cooling tower to preventcontamination of cooling water by exhaust gas from flues.
15. If required, fit the rupture disk on the chiller according to therupture disk manual.
16. Separate chilled and cooling water pumps should preferablybe provided for each chiller.
17. Provide an expansion tank in the chilled-water line.18. There should be sufficiently large clearance for easy access to
the evaporator, absorber and condenser, to facilitateinspection and cleaning work.
