Introducing the SANYO absorption chillers:

SUPER ABSORPTION

SANYO absorption chillers highlights

SANYO, as a leading company in this field more then 20 years in domes- tic market in Japan, now brings the high efficiency of double-effect steam chillers and double-effect direct-fired chiller/heaters to the world market.

The SANYO absorption chillers and chiller/heaters give building owners a better solution for many new and retrofit applications. Installation of a direct-fired chiller/heater eliminates the need for the boiler required with conventional installations. This reduces the initial cost of the system, mak- ing a SANYO chillers/heaters competitive with conventional chiller/boiler system.

The SANYO absorption chillers and chiller/heaters offer a number of other advantages:

• Excellent for peak shaving during high electrical demand periods.

• Replaces existing inefficient single-stage absorption chillers without an

expensive electrical service upgrade.

•Allows for smaller emergency generators to be utilized since the elec- trical load associated with an absorption chiller is minimal when com- pared to an electrical driven chiller.

•Ozone safe, CFC free. Cooling requirements are met without chlorine based refrigerants.

•Reduces contribution to global warming. Minimizes global impact by greatly reducing electricity consumption and eliminating the use of greenhouse gases.

•Low noise and vibration. The absorption chiller does not utilize a large motor-compressor, and this leads to quiet, trouble-free operation.

•Small footprint. The high efficiency associated with the double-effect chiller has reduced the space required for installation.

SANYO is the industry leader in supplying compact units.

•CE marking is applicable if requested.

With the ever-changing requirements of building owners and continual changes in building designs, SANYO introduces to the world market the next generation of high efficiency gas and steam fired, double-effect ab- sorption chillers.

Electrical peak power shaving

By using a combination of electric driven and absorption chillers for air conditioning loads, a central plant can take advantage of lower base elec- tricity rates during times of high electricity demand. The absorption unit is used to shave peak power demands during summer operation, while operating the electric chiller below the assigned demand limit, avoiding costly demand charges and saving money all year-round.

In many parts of the world, the cost of electricity and penalties adminis- tered through demand limits, inverted rates, time-of-day rates, ratchet clauses, etc., have forced the need for alternative chiller systems to be developed.

With the aging of the world power plants and environmental and financial concerns blocking construction of new ones, many areas are faced with extremely high demand charges and escalating electricity costs. In these areas, the entire cooling load can be handled by SANYO absorption units, allowing the allotted electricity to be used elsewhere in the building where there are no practical alternatives.

• Has the ability to tie into district steam systems with an efficient double-

effect chiller.

• Allows diversification of critical cooling requirements. Critical cooling

loads are met with minimal electrical power input with gas or steam

fired chillers.

Heating and cooling operation

Many applications

The SANYO offers the broadest range of equipment and operating con- ditions in the entire industry: 23 discrete unit sizes from 100 tons to 1500 tons incorporating either direct-fired or steam-fired generators. With natural gas as one of the heat sources for direct-fired types, the customer can be assured of a fuel that is clean burning and environmentally friendly.

The SANYO steam-fired, double-effect chiller satisfies the building owner's need for high efficiency replacement/retrofit units plus an optimal solu-

tion to new high pressure steam chilling systems. A SANYO double-ef- fect steam chillers is the perfect complement to a district steam heating system, offering single source heating and cooling.

The SANYO hot water-fired chillers is applicable not only combined in Co-generation system but utilized the waste heat as a driving heat source in the various applications.
