New approach to the estimation of heat pumps efficiencyKeywords: heat pumps , application , efficiency , power balance , exergy balance. Abstract: A new approach to the estimation of heat pumps efficiency on the basis of power and exergy balances is described in the paper. Some new parameters of efficiency estimation of the system "Thermal power station – thermal pump – consumer" are discussed. Parameters, which allow to fully estimate their efficien-cy and to provide the set time of recoupment at the stage when conditions of thermal pumps application are used, are established.
