Description
Technical field
The present invention relates to art of refrigeration units, specifically a kind of wide temperature feed flow liquid low-temperature receiver.
Background technology
Along with Highgrade integration and the scale of electronic device, cooling is also had increasingly stricter requirement by the heat-producing device such as laser, radar, it is necessary to adopt special liquid low-temperature receiver to provide its normal operation of coolant guarantee.
The feed flow temperature range of liquid low-temperature receiver is had different requirements by different electronic equipments, meanwhile, even if same electronic equipment also has different requirements to for liquid temp under different working conditions.For ensureing the normal operation of these electronic equipments, it is necessary for requiring that liquid low-temperature receiver is to its self-adjustable ability that must have in a big way for liquid temp；In the relatively low situation of feed flow temperature requirement, adopt the conventional compressor refrigeration system can normal operation, if and in the higher situation of feed flow temperature requirement (more than 25 DEG C), conventional compressor refrigeration system there will be, in running, the problem that evaporating temperature is too high and suction temperature is too high, the too high meeting of evaporating temperature causes the overload of compressor electric motor, suction temperature is too high, can cause exceeding standard of compressor exhaust temperature, and under both operating modes, long time running all can cause the shortening in refrigeration compressor life-span.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wide temperature feed flow liquid low-temperature receiver, solves the too high problem causing compressor electric motor to transship of evaporating temperature.
The technical scheme is that
A kind of wide temperature feed flow liquid low-temperature receiver, include refrigeration system, coolant circulation system and electric-control system, described refrigeration system includes sequentially circulating the compressor of connection, condenser, throttling arrangement and vaporizer, coolant circulation system includes liquid storage water tank and solution feed pump, the liquid outlet of liquid storage water tank is connected with the refrigerating medium inlet of vaporizer by solution feed pump, the refrigerating medium liquid outlet of vaporizer, liquid storage water tank inlet be connected with external heat load respectively；The liquid outlet of described condenser passes sequentially through electric control valve, choke valve is connected with the inlet of compressor；The pipeline that the air vent of described compressor and the air inlet of condenser connect is provided with temperature sensor；Described temperature sensor, electric control valve are connected with electric-control system respectively.
The gas returning port front end of described compressor is connected to pressure-regulating valve, the outlet of described choke valve, vaporizer gas outlet be all connected with pressure-regulating valve.
Described pressure-regulating valve selects crankcase pressure to regulate valve.
Advantages of the present invention:
The delivery temperature of collect and process machine is responsible in the temperature sensor of the present invention, it is then transferred to electric-control system, when the temperature collected is too high, electric-control system can open electric control valve, making the liquid outlet of condenser connect with the inlet of compressor, the liquid refrigerant of fractional distilling tube condensation becomes the gas-liquid two-phase state of low-temp low-pressure through throttling valve action, then with the gas hybrid cooling of the higher temperature of evaporator evaporation, the problem avoiding compressor electric motor overload, improves the service life of unit；The crankcase pressure of the present invention regulates valve and ensures that compressor return air pressure is less than setting value, it is ensured that unit normal operation；The present invention adopts automatization's sensing control mode, and control mode is simple, safeguards that monitoring is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
See Fig. 1, a kind of wide temperature feed flow liquid low-temperature receiver, include refrigeration system, coolant circulation system and electric-control system 9；Refrigeration system includes sequentially circulating the compressor 1 of connection, condenser 2, throttling arrangement 3, vaporizer 4 and crankcase pressure and regulates valve 5, realize the function that the coolant flowing through vaporizer 7 is lowered the temperature, and the liquid outlet of condenser 2 pass sequentially through electric control valve 6, choke valve 7, crankcase pressure regulate valve 5 be connected with the inlet of vaporizer 4, being provided with temperature sensor 8 on the pipeline that the air vent of compressor 1 and the air inlet of condenser 2 connect, temperature sensor 8, electric control valve 6 are connected with electric-control system 9 respectively；Coolant circulation system includes liquid storage water tank 10 and solution feed pump 11, and the liquid outlet of liquid storage water tank 10 is connected with the refrigerating medium inlet of vaporizer 4 by solution feed pump 11, the refrigerating medium liquid outlet of vaporizer 4, liquid storage water tank 10 inlet be connected with external heat load respectively.
The operation principle of the present invention:
The delivery temperature of collect and process machine 1 is responsible in temperature sensor 8, it is then transferred to electric-control system 2, when the temperature collected is too high, electric-control system 2 can open electric control valve 6, the liquid outlet of condenser 2 is made to connect with the inlet of compressor 1, the liquid refrigerant of fractional distilling tube condensation can be substituted by the capillary tube of suitable length and caliber through choke valve 7() act on the gas-liquid two-phase state becoming low-temp low-pressure, then with the gas hybrid cooling of the higher temperature of vaporizer 4 evaporation, the gas of mixing regulates valve 5 adjustment through crankcase pressure and makes the not super setting value of compressor 1 back pressure, finally it is drawn back in compressor 1 and is compressed, then circularly cooling successively.
