WFC SC chillers from Yazaki are single stage hot water driven
chillers. Compared to electrically driven chillers the WFC SC series
can dramatically lower system operating costs when using waste heat.
Applications particularly well suited to the Yazaki WFC SC absorption
chiller include waste heat recovery from cogeneration or biomass,
waste heat from district power station or industry as well as solar
thermal. This makes absorption cooling an environmentally friendly and
cost-saving alternative to conventional air-conditioning systems. A low
electrical energy consumption results in low CO 2 emissions and provide
a relief for electricity grids by replacing conventional cooling demand
peaks. All chillers are pre-filled and ready for “plug & chill”. Natural gas-fired chiller/heaters CH K & CH MG from Yazaki work
with double effect thermo-cycle and may be used for both cooling or
heating distribution. Compared to electrically driven chillers CH K & CH
MG chillers can dramatically lower system operating costs.
Driving heat source hot water
WFC SC units can operate with entering hot water temperature from
70 to 95°C. Refrigerant cycle
The Yazaki CH K & CH MG high efficiency double-effect absorption
refrigeration cycle uses water as the refrigerant and lithium bromide
(non-flammable, non-toxic, ecologically benign and ozone-friendly) as
the absorbent. It is the strong affinity and ease of separation that these
two substances have for each other that makes the cycle work. The
entire process occurs in hermetic vessels in a near complete vacuum.

Direct fired chiller
Driving energy is provided by natural gas. Typically a COP of 1.0 or
above is achievable.
