The analysis of energy efficiency of heat pump-adsorption system of conservation of power equipment taking into account real processes of dehumidification and humidification of air in adsorption rotor in comparison with energy efficiency of standard system with electric heater of regenerative air is performed. The analysis shows that the heat pump-adsorption system is many times more energy-efficient under the condition of not only theoretical but also real (non-isoenthalpy) working processes in the adsorption rotor. It is also shown that there are optimal values of regeneration air temperature after the heat pump condenser at the inlet to the rotor, at which the energy efficiency of the heat pump-adsorption system reaches maximum values. It is established that the optimal values of regeneration air temperature change in a narrow range (at the level of 60...65 0С), and the maximum values of energy efficiency coefficient significantly decrease for a standard system with electric heater and increase for heat pump-adsorption system with decreasing ambient temperature.
