FIELD: heating, ventilation.
SUBSTANCE: invention refers to the device and method to be used with air conditioning cycle. A turbine for power generation includes a rotor, a chamber and at least one nozzle for supply of a fluid medium to activate the rotor. Flow of the fluid medium out of the nozzle output is periodically interrupted with at least one device of the flow brake to increase fluid medium pressure inside the nozzle. In a thermo dynamic cycle two such turbines can be used; at that the first turbine is located after a compressor and before a heat exchanger, and the second turbine is located after an evaporator and before the compressor. The invention facilitates upgrading of a total efficiency owing to recuperation of a portion of energy.
EFFECT: upgraded efficiency of an air conditioning device.
