Single Effect hot water driven absorption chiller

YHAU-CL / CH
Two Step Evaporator and Absorber Design
Efficiency , Reliability , Cost of Ownership 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 seriescounter-flow arrangement splits the work between two chillers . The result of the design allows the YHAU-CL / CH 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 / CH can take advantage of 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 .
Full Automatic Purging System 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 .
Chiller control 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 .
