摘　　要：An analysis of the thermal characteristics of the industrial thermocompression heat pump systems is presented in this paper By using thermocompression, waste heat is thermotransformed to a higher temperature level to be convenient for its usage in thermal processes. The thermocompression heat pumps can be optimally applied in various industrial plants （production of fruit, grape and tomato concentrates, in beer, sugar and dairy industries, in chemical and pharmaceutical industries etc.）. The range of optimal application of the turbo compressor, screw compressor and ejector thermocompression is estimated. The complex thermal and flow phenomena in the processes of thermocompression, evaporation and condensation are discussed. The theoretical and experimental results of the investigations on the experimental grape vacuum concentrator and on the industrial NaOH concentrator are presented. A significant increment of the energy efficiency can be achieved by optimal application of the thermocompression in the thermal concentrating processes. A significant feature and great advantage of the concentrating technology with thermocompression are a possibility for realization of the low temperature concentrating processes, which is very important for the quality of many concentrating products with high energy efficiency technology.
