THERMAL PUMP Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: thermal pump includes evaporator 1, compressor 2 and condenser 3 connected in series. Compressor is driven by electric motor 4; condenser 3 is provided with condensate drain branch pipe 5. Evaporator 1 has closed reservoir 6 with device 7 for finely dispersed spraying of water low-potential loop through recirculating pump 9. Condenser 3 is connected to high-potential loop through recirculating pump 10. Device 7 for finely-dispersed spraying consists of central dispensing pipe line 11 for delivery of water of low-potential loop and circular pipe lines fitted with spraying injectors and brought in communication with this loop. Circular pipe lines are fitted on central pipe line 11 at pitch; injectors of each circular pipe line have different length. EFFECT: enhanced efficiency. 3 cl, 2 dwg
