Heat transfer from one temperature level to some another can be carried out to produce cooling effect; to decrease the temperature of high-grade heat source for a specific purpose, for example, in the systems of heating and hot water supply, to increase the temperature of low-grade source. The article deals with the influence of internal heat regenerating rateon the energy efficency of the the cycles in absorbtion lithium bromide step-down thermal transformer, absorbtion lithium bromide refrigerating unit, and absorbtion lithium bromide step-up thermal transformer depending on the temeperture of heat source.

Keywords: heat transfer, cycle system, refrigerating unit, thermal transformer, coefficients of cycle energy efficiency, the temperature of heat source.
