Detailed description of the invention

As it is shown in figure 1, a kind of energy-saving steam compression-type refrigeration blood circulation, including compressor 1, condenser 2, subcooler 3, the hydraulic turbine 4, choke valve one 5-1, choke valve two 5-2, vaporizer 6, supercharger 7, shaft coupling 8, wherein compressor 1 is cold-producing medium Circulation provides power；Condenser 2 is refrigerant cooler, makes cold-producing medium heat release cooling under the effect of cooling medium；Supercool Device 3 is cold-producing medium supercooling apparatus；The hydraulic turbine 4 is the equipment that pressure can be converted to mechanical energy, according to the operation principle of the hydraulic turbine, choosing Select the hydraulic turbine and replace the expansion valve in the circulation of existing steam compression type refrigeration, make the pressure of refrigerant liquid to be within it converted to Mechanical energy drives supercharger work, thus improves the pressure of low-pressure refrigerant vapor, and makes compressor suck higher than evaporating pressure Refrigerant vapour, reduce the pressure reduction of turnover compressor refrigerant steam, thus reduce power consumption；Vaporizer 6 is cold-producing medium Evaporation endothermic device, makes refrigerant suction coolant media heat of vaporization；Supercharger 7 is refrigerant vapour supercharging equipment；Specifically, Compressor 1 import is connected with supercharger 7 outlet by pipeline, and compressor 1 is exported and is connected with condenser 2 import by pipeline, cold Condenser 2 is exported and is connected by the high pressure refrigerant inlet of pipeline with subcooler 3, and the high-pressure refrigerant outlet of subcooler 3 is by pipe Road is connected with the hydraulic turbine 4 import, and the low pressure refrigerant import of subcooler 3 is connected with choke valve one 5-1 outlet by pipeline, supercool The low pressure refrigerant outlet of device 3 is exported by pipeline be all connected with supercharger 7 import, vaporizer 6, and the hydraulic turbine 4 outlet is passed through Pipeline connects choke valve one 5-1, the import of choke valve two 5-2 respectively, and vaporizer 6 import is gone out with choke valve two 5-2 by pipeline Mouth connects, and supercharger 7 is exported and is connected with compressor 1 import by pipeline, and the hydraulic turbine 4 wheel shaft is by shaft coupling 8 and supercharger 7 Power transmission shaft connects, thus drives supercharger 7 to work.

Its operation principle is, first, refrigerant vapour is inhaled into compressor 1, and insulated is collapsed into superheated steam, so Refrigerant vapour under rear superheat state enters condenser 2, is become saturated liquid by level pressure condensation, this saturated liquid subsequently into Subcooler 3, continues to be cooled to subcooled liquid, and in then subcooled liquid enters the hydraulic turbine 4, acting, makes the pressure of refrigerant liquid Within it can be converted to mechanical energy thus drive supercharger 7 to work, in the hydraulic turbine 4, make the refrigerant liquid pressure of merit simultaneously Declining, be then divided into two parts, the most respectively by choke valve one 5-1, choke valve two 5-2 adiabatic throttling, pressure continues to reduce, joint Low-temperature low-pressure refrigerant after stream respectively enters subcooler 3, vaporizer 6, on the one hand in subcooler 3, and low-temperature low-pressure refrigerant Absorbing the high-pressure refrigerant heat of vaporization come from condenser 2, reduce high-pressure refrigerant temperature, high-pressure refrigerant was cooled into Cold liquid, high-pressure sub-cooled liquid enter hydraulic turbine work done, the temperature of subcooled liquid regard the hydraulic turbine 4 work do not produce vaporize and Fixed, it is ensured that pressure remains liquid condition when declining, and while ensureing that the hydraulic turbine 4 is properly functioning, play bigger system Cold effect；On the other hand in vaporizer 6, low-temperature low-pressure refrigerant absorbs coolant media heat of vaporization, and coolant media releases heat Amount temperature reduces, it is achieved refrigeration purpose, is finally entered by the low-temperature low-pressure refrigerant steam after subcooler 3, vaporizer 6 evaporation endothermic Row mixing, enters supercharger 7 supercharging, improves the pressure of refrigerant vapour, be inhaled into the most again compressor 1 after mixing, and The insulated refrigerant vapour being collapsed under superheated steam, superheat state enters condenser 2, is become saturated solution by level pressure condensation Body, continues to be cooled into subcooled liquid subsequently into subcooler 3, the most constantly circulation.
