A vapor-air thermocompressor intended for recuperation of low-potential heat is examined. A modernized sliding-vane vacuum compressor (4 kW) and appropriate jet blower are basic components of the thermocompressor. Experiments with various types and cross sections of nozzles in the jet blower are described. Water flows discharging from the nozzle are analyzed, and various mixing shafts tested. The interrelation between the coefficient of ejection and the geometric characteristics of the jet blower is established for the case in question on the basis of experimental data. A procedure is cited for detailed analysis of the effective circuit of the thermocompressor and its basic components: jet blower, vacuum compressor, circulating pump, and heat exchanger of the recuperator and condenser. An example is cited for analysis of a 20-kW thermocompressor with an effectiveness E > 3 on the basis of a vacuum compressor manufactured by the Tekhnolit Plant (Polotsk) and a designed jet blower.
