Wood Fired Cooling

When the heat medium inlet temperature exceeds 154.4°F, the cooling unit springs into action. Max cooling is with 190.4F; very doable with out 75%+ efficient wood boiler!

Power Consumption is a little as 48 Watts, single phase for their smallest unit and 210 Watts (3 phase) for the next size up, on up to 670 Watts for their 600 MBTUh model and even LESS for their BIGGEST 1200 MBTUh unit!  VERY MINIMAL compared to a typical power hungry A/C unit!  That is the rating on the Yazaki unit alone and does not include external pumps or fan motors.  

Much like an auto air conditioning system, this uses an orifice; where refrigerant liquid accumulates in the condenser sump and then passes through an orifice into the evaporator.

Features and Benefits

•

• Ideal for heating when used in a two-pipe system 
with properly sized water coils. (WFC-SH models only)

 

• Mode and Enable/Disable condition can be selected remotely.

 

••Only a 30-minute changeover delay between cooling and heating modes. (WFC-SH models only)

 

• The absorption cycle is energized by hot water. 

• This hot water can be from any source such as a wood boiler, 
cogeneration, solar, or any waste heat source as long as it can be provided

to the chiller or chiller-heater at a temperature between 158°F to  203°F, which the Hyprotherm boilers will easily do!

 

• Extended capacities available when supplied with cooling water colder than design standard of 87.8°F 
(WFC-M designstandard 85°F) and/or heat medium warmer than design standard of 190.4°F (WFC-M design standard 194°F)

.

• Faster cold start-up time (as quick as 90 seconds) than similar chillers with flooded generators.

• Working fluids of lithium bromide and water operate

under a vacuum at all times and are safe, odorless and non-toxic.

 

• Only one rotating part: the hermetically sealed solution pump.

 

• Vacuum vessel fully hermetically sealed at the 
factory for a level of vacuum integrity that is unmatched in the industry.

No field welding necessary.

 

• Helps to prevent crystallization by utilizing a 
solution pump and gravity drain-back design.

 

• Chilled and hot water outlet temperatures controlled by a built-in microprocessor with outputs to 
control a 3-way heat medium bypass valve, all relevant pumps, and even 
the cooling tower fan (if so desired). All valves and pumps are

field-supplied. Alternatively, the valves are available as a factory-supplied 
but field-installed option.

 

• Built-in logic will shut down the unit under abnormally high heat medium and/or cooling water 
temperatures to help prevent crystallization and other service-related issues.

 

• Proprietary solution and inhibitor blends ELIMINATE

the need for regular chemical analysis of working

fluids within the unit, resulting in much simpler regular 
maintenance when compared with most other manufacturers.

 

• All chillers and chiller-heaters are supplied with

UL50E Type 3R cabinets that are suitable for indoor

or outdoor installation without modification. See Wood Fired Cooling Brochure for sizes

 

• Factory charged and run tested. Solution balancing

done at the factory so that it does not need to be

done in the field at startup potentially eliminating DAYS of 
necessary commissioning time when compared with 
other manufacturers.
