capacities ranging from 360kW to 1.1MW and impressive EER values of between 5.2 and 5.35 at full load, rising as high as 8.0 at 50% partload. Chilled water is supplied at between 4 and 16 C with a leaving condenser water temperature of between 30 and 50 C. For process or ice-storage applications chilled water down to -5 C is optional.

single screw compressor with high efficiency motor, optimised for use with R-134a. Modulating the sliding valve position according to chilled water temperature enables the compressor to closely match capacity requirements resulting in high part load efficiencies and stable chilled water temperatures with better control regulation. Capacity control of the single circuit EWWD unit in fact, is infinitely variable between 25 and 100%.

(Air Conditioning System)

This hybrid HVAC tech is so cool and so hot - including the possibility of using direct solar collectors to cool and heat our buildings- we're surprised it hasn't had very much media coverage of late. From the Yazaki Energy Systems, Inc. web site (Plano Texas, USA) Yazaki water fired SINGLEEFFECT chillers or chiller-heaters have cooling capacities of 10, 20 and 30 tons of refrigeration and produce chilled water for cooling or hot water for heating in comfort air conditioning applications. The absorption cycle is energized by a heat medium (hot water) at 158F to 203F from an industrial process, co-generation system, solar energy or other heat source and the condenser is water cooled through a cooling tower. Absorption Principle:The Yazaki absorption chiller or chiller-heater uses a solution of lithium bromide and water, under a vacuum, as the working fluid. Water is the refrigerant and lithium bromide, a nontoxic salt, is the absorbent. Refrigerant, liberated by heat from the solution, produces a refrigerating effect in the evaporator when cooling water is circulated through the condenser and absorber.
