Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the energy-saving injector refrigerating circulatory device peculiar to vessel of the utility model.
Fig. 2 is the structural representation of the utility model injector.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Energy-saving injector refrigerating circulatory device peculiar to vessel, comprise compressor 1, the condenser 2 that links to each other with compressor 1 pipeline, condenser 2 connects high temperature freezer 4 and low-temperature cold store 6 by a plurality of pipelines, at condenser and height, low-temperature cold store 4, has heating power expansion valve on 6 pipelines that connect, high, low-temperature cold store 4,6 by pipeline connection injector 5, injector 5 is connecting compressor 1 by pipeline, described injector 5 has two inlets 51,52 1 outlets 53, an inlet 51 of injector 5 connects high temperature freezer 4 by pipeline, another inlet 52 connects low-temperature cold store 6 by pipeline, and outlet 53 connects compressor 1 by pipeline.
Described injector 5 profiles are dumb-bell shape, the centre has the throat 54 of a constriction, the axial direction of throat's 54 1 ends has a high temperature freezer refrigerating agent import 51, side in high temperature freezer refrigerating agent import 51 has a low-temperature cold store refrigerant inlet 52, medial surface in high temperature freezer refrigerating agent import 51 and low-temperature cold store refrigerant inlet 52 has a tubaeform mixing chamber 55, and the other end of throat 54 is a tubaeform diffuser 56.
The course of work is as follows: compressor 1 will be become the gas of uniform temperature, certain pressure by the refrigerant vapor compression that muffler comes, through condenser 2 gaseous refrigerant is cooled to liquid then, be divided into two-way subsequently again and flow to high and low temperature freezer 4,6 through heating power expansion valve respectively, liquid refrigerant flashes to gaseous state in freezer, draw the heat in the freezer, thereby reach the effect of refrigeration.The high-pressure gaseous cryogen that high temperature freezer 4 evaporimeters come out is as the working fluid of injector 5, and the low pressure gaseous state cryogen that low-temperature cold store 6 evaporimeters come out is as the driven fluid of injector 5.Working fluid is through the nozzle adiabatic expansion, and pressure constantly reduces, and speed improves constantly, and reaches very high speed in the exit of nozzle, thereby has very big kinetic energy.The refrigerant vapour that high temperature freezer 4 flows out comes out from nozzle flow with very high speed, enters the receiving chamber of injector 5, and the lower driven fluid of pressure in receiving chamber is siphoned away.5 li of injectors, be that potential energy or the heat energy that the refrigerant vapour of high temperature freezer outflow takes place is transformed into kinetic energy at first.The kinetic energy of the refrigerant vapour that the high temperature freezer flows out, a part has been passed to the refrigerant vapour that low-temperature cold store flows out, along in the injector process of flowing, the speed of fluid-mixing is balanced gradually, so the kinetic energy of mixed refrigerant vapor changes potential energy or heat energy on the contrary in diffuser.The refrigerant vapour pressure that comes out from diffuser is between the refrigerant pressure that refrigerant vapour pressure that high temperature freezer evaporimeter comes out and low-temperature cold store evaporimeter come out.
In injector 5, two kinds of fluids carry out the momentum-exchange and the supercharging of slowing down, thereby high temperature evaporation pressure is reduced, low-temperature evaporation pressure raises, and the compressor admission pressure improves, and delivery temperature reduces, refrigerating effect per unit swept volume rises, and can reach purpose of energy saving, increases economic efficiency.
