The innovative 2-step evaporator and absorber design is more efficient than a conventional cycle. This ingenious
design splits the absorption process into two steps, similar to how a series-counter-flow arrangement splits the work
between two chillers. The result of the design allows the YHAU-CL to perform the absorption function with lower
solution concentrations than conventional designs, increasing efficiency and reliability, and decreasing cost of
ownership.
Reliability is enhanced because the solution concentrations are lower leaving the absorber, which allows the entire
cycle to operate at lower concentrations virtually eliminating the possibility of crystallization.Efficiency is enhanced because the YHAU-CL can take advantageof lower than normal hot water temperatures in the generator. This is because
at lower concentrations the solution will boil at a lower temperature in the generator.
Lastly, total operating cost decreases because of the lower concentration of the solution entering the generator, a wider
temperature range of hot water can be used, reducing pumping horsepower.
As a standard feature, the unit has a fully automatic purging system comprising of electronic vacuum transmitter,
solenoid valves and trending capability that ensures design performance and improves reliability. The operator does
not have to worry about the sequence of purging for removing the non-condensable gases.
The YHAU Control Center, standard on each chiller, provides the ultimate in efficiency, monitoring, data recording, chiller protection and operating ease.
The LCD display allows graphic animated display of the chiller, chiller sub-systems and system parameters; this allows the presentation of several operating parameters at once. In addition, the operator may view a graphical representation of the historical operation of the chiller as well as the present operation. The panel is capable of communication with
building management systems and is available in multiple languages.
