Absorption Chillers and Heat Pumps
Cool. Cap.: 17-176 kW, single-stage hot water
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 CO2 emissions and provide a relief for electricity grids by replacing conventional cooling demand peaks. All chillers are pre-filled and ready for “plug & chill”.
The Yazaki WFC SC high efficiency single-stage 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.
