There are many types of lithium bromide absorption chiller, such as the two-stage lithium bromide absorption chiller, which can effectively use high pressure heating steam; Two-stage absorption lithium bromide absorption chiller, which can effectively use the low temperature thermal energy; Direct fired lithium bromide absorption refrigerating machine can be heated directly by oil or gas combustion.
The lithium bromide absorption refrigerating machine can also form a combined unit with the back pressure steam turbine. The exhaust steam of the steam turbine is used as the heating steam of the lithium bromide absorption refrigerating machine. In this way, the utilization rate of water steam can be improved and several requirements can be met at the same time, such as refrigeration and power generation. According to this idea, a refrigeration unit with lithium bromide absorption chiller and centrifugal freon chiller has been designed.
It uses the back pressure steam turbine to drive the centrifugal compressor directly, and uses its exhaust steam to heat the lithium bromide absorption refrigerator. This unit can produce large cooling capacity, and can also produce cooling capacity at different evaporation temperatures. This kind of unit not only has good economy (low steam consumption rate), but also has good low load characteristics, that is, it can still maintain high economy at partial load.
