Applications of absorption chillers.

Summary

Absorption lithium bromide groups, for their type of operation and their characteristics, are particularly interesting not only in the ecological field but also in the field of energy saving. From the point of view of ecology should be noted that groups such as the working fluid absorption, the aqueous solution of lithium bromide, has practically no impact on the environment. The refrigerants used in compression machines instead of gas have an impact even on the small decrease of the ozone layer and global warming. In the field of energy conservation, the absorption units on the market today, particularly those produced EBARA, have been profoundly improved for efficiency and are particularly suitable for the reuse of all waste heat, are widespread in many industrial processes. In integrated production of electricity, as is known, heat is a by-product present at continuously variable thermal levels. Its non-use is a net loss of overall efficiency of the process. The action in these cases the recovery of heat absorption units can increase overall system performance to levels that will improve the economic situation. In any case represent a significant improvement in terms of energy savings. Groups to direct flame, due to high values of COP due to the continuous improvements introduced, have a lower consumption of primary energy in terms of the order of 27% compared to conventional technologies based on a gas compression refrigeration equipment. This percentage is not always fully reflected in economic, as the price of electricity and natural gas are different from case to case, it should not be forgotten, however, contributing to lower emissions of carbon dioxide in the same order of magnitude.
