Abstract
The utility model provides a coolant overcooling jet expansion steam compression refrigerator, which is characterized in that the high-pressure coolant liquid of a condenser, via an electric adjusting valve is adjusted at pressure, but not via prior jet pump input, and via a gas-liquid separation overcooling device is overcooled to be guided into a jet pump input, to be mixed with the coolant steam in a evaporator, leaded by a jet opening of the jet pump, to be compressed into the gas-liquid separation overcooling device. The high-pressure overcooling coolant liquid, via pressure adjustment and overcooling, is leaded into the input of a jet pump, thereby improving the efficiency of jet pump, and further improving system efficiency. And the high-pressure coolant liquid via a gas-liquid separation overcooling device is overcooled, to accelerate the evaporation of coolant liquid in the gas-liquid separation overcooling device, and eliminate the over accumulation of coolant liquid in the overcooling device, to make the refrigerating system normally work.
Description
Technical field
The utility model relates to a kind of steam compressing refrigerating device, and particularly a kind of cold-producing medium is crossed cold shooting flow expanding steam compressing refrigerating device.
Background technology
In conventional vapour compression refrigeration system, after high pressure refrigerant liquid is discharged from condenser, be throttled to evaporating pressure through choke valve, can cause energy loss, in order to reclaim the energy that loses in the cold-producing medium step-down process, propose at present with the high pressure refrigerant liquid of condenser and by refrigerant vapour in the evaporimeter of jet pump air entry injection, be compressed to the vapour-liquid separator by jet pump together, like this, stockpile part of refrigerant liquid, enter evaporimeter through the second throttle valve, and the refrigerant vapour in the vapour-liquid separator is directed to the suction compressor inlet at the vapour-liquid separator, compressed machine compression is delivered to condenser, continues systemic circulation.Above-mentioned vapor compression refrigeration system because jet pump efficient is low, causes the vapour-liquid separator to stockpile too much refrigerant liquid easily, influences systemic circulation and normally carries out.
Summary of the invention
The purpose of this utility model is to provide a kind of cold-producing medium to cross cold shooting flow expanding steam compressing refrigerating device, by improving jet pump efficient, reduces the vapour-liquid separator and stockpiles too much refrigerant liquid, and systemic circulation is normally carried out.
In order to realize above-mentioned purpose, the technical solution of the utility model is: condenser separates subcooler through electric control valve and links to each other with vapour-liquid, vapour-liquid is separated subcooler and is linked to each other with the high pressure refrigerant liquid input port of jet pump, make the high pressure refrigerant liquid of condenser output, by the existing jet pump input port of directly guiding into, change into earlier through the electric control valve pressure regulation, it is cold excessively to separate subcooler through vapour-liquid again, guide the jet pump input port into, after refrigerant vapour in the evaporimeter that the jet pump ejecting port sucks mixes, be compressed to vapour-liquid separation subcooler by jet pump together.
The high pressure refrigerant liquid flow path of above-mentioned condenser output, make high pressure refrigerant liquid through pressure regulation, cross cold after, guide the technical measures of jet pump input port again into, the efficient and the evaporation that helps refrigerant liquid in the vapour-liquid separator of jet pump have been improved, eliminate in the vapour-liquid separation subcooler and stockpile too much refrigerant liquid phenomenon, the refrigeration pump systemic circulation is normally carried out.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 forms schematic diagram for the utility model structure.
Fig. 2 is the utility model thermodynamic cycle figure.
The specific embodiment
Referring to Fig. 1, the utility model cold-producing medium is crossed cold shooting flow expanding steam compressing refrigerating device and is comprised: compressor 1, and condenser 2, electric control valve 3, jet pump 4, evaporimeter 5, vapour-liquid is separated subcooler 7.Wherein, condenser 2 links to each other with the high pressure refrigerant liquid input port of jet pump 4 through electric control valve 3 and vapour-liquid separation subcooler 7.During the utility model operation, the high pressure refrigerant liquid of condenser 2 is cold excessively through electric control valve 3, vapour-liquid separation subcooler 7, after ejecting port by jet pump 4 refrigerant vapour that sucks evaporimeter 5 mixes then, by jet pump it is compressed to vapour-liquid together and separates subcooler 7; Vapour-liquid is separated the air inlet that refrigerant vapour in the subcooler 7 is inhaled into compressor 1, and a refrigerant liquid part enters evaporimeter 5 evaporations through second throttle valve 6, and another part evaporative cooling is from the high pressure refrigerant liquid of condenser 2, and makes it cold excessively.8 for placing the temperature sensor at compressor 1 air intake place, and control electric control valve 3 and second throttle valve 6 make the vapor compression refrigeration system periodic duty in optimum state.Second throttle valve 6 can adopt forms such as heating power expansion valve, electric expansion valve, orifice plate.In addition, remainder of the present utility model is identical with conventional system.
Referring to Fig. 2, among the thermodynamic cycle figure of the present invention.11-12 is the compression process that is compressed to condensing pressure from the refrigerant vapour that subcooler is discharged compressor; 12-13 is a condensation process; 13-13 ' is the cold process of mistake of the high pressure liquid refrigerant that the cold condenser of the evaporative cooling of cold-producing medium comes out in the subcooler; The 13 '-14th, the expansion process of liquid refrigerant in jet pump; 14-15 and 0-15 are jet cold-producing mediums and by the mixed process of injection refrigerant vapour; 15-16 is the compression process of mixed cold-producing medium at the jet pump diffuser; 17-18 is that refrigerant liquid in the subcooler is to the throttling expansion process of evaporimeter; The 18-0 cold-producing medium is in the evaporation process of evaporimeter.State point 14 is on saturated liquid line MN in the circular chart.
Beneficial effect
The utility model refrigeration agent over cool ejection flow expansion steam compression refrigeration adopts in the future self cooling condenser High pressure refrigerant liquid through vapour-liquid separate subcooler cross cold after, improved vapour-liquid and separated in the subcooler The evaporation of refrigerant liquid, the refrigerant liquid of having eliminated in the vapour-liquid separation subcooler stockpiles phenomenon, with The time, because high pressure is crossed the jet of cold cold-producing medium, improved the efficient of jet pump, therefore improved refrigeration system The efficient of system has guaranteed normally carrying out of systemic circulation.
