Agent pipeline is also classified into main road and bypass, and refrigerant compression is reentered by economizer after the heat of the refrigerant suction main road of bypass
Machine, the refrigerant of main road enter heat exchanger and carbon dioxide are freezed.The operating mode for condensing unit can be carried out as needed
Regulation.
Preferably, the condenser, which is set, presses table and refrigerant high pressure gauge in refrigerant low-pressure meter, refrigerant.Data are directly perceived, side
Just operating mode is adjusted according to expansion valve.
Preferably, the return line of the refrigeration compressor is provided with gas-liquid separator.Isolate and preserve compressor
Liquid in return duct is to prevent compressor liquid hammer.
Preferably, the heat exchanger uses stainless steel tubular heat exchanger.Evaporator uses stainless steel shell and tube, heat exchange
Effect is more preferable.
Preferably, the unit uses PLC control system, band text display can consersion unit running status directly perceived.
So that control is accurate, moreover it is possible to shows defect content, such as refrigerant high pressure, refrigerant low pressure, power phase failure.
The beneficial effects of the utility model are：Using carbon dioxide at different temperatures have different saturated vapor pressures this
One characteristic, by changing gas temperature and pressure, make co 2 liquefaction, so as to meet industrial production demand.Floor data is straight

Embodiment
The utility model is further described below by embodiment and accompanying drawing.
Embodiment is：As Figure 1-3, a kind of carbon dioxide cryogenic condensation unit, including installed in machine
Frame is used for the heat exchanger 3 of carbon dioxide condensation, the refrigeration system for refrigerant circulation and for separating refrigerant
And allow the oil circulating system of lubrication oil circulation.Heat exchanger 3 uses stainless steel tubular heat exchanger；Refrigeration system is included in frame
Refrigeration compressor 1, condenser 4 and the economizer 7 independently assembled, the return line of refrigeration compressor 1 are provided with gas-liquid separator
6；Oil circulating system is included in the oil eliminator 2 and oil cooler 5 independently assembled in frame；Refrigerant low pressure is set in condenser 4
Table and refrigerant high pressure gauge are pressed in table, refrigerant, and is provided with two expansion valves, respectively main road expansion valve and bypass expansion valve, phase
The refrigerant line answered is also classified into main road and bypass, is entered again by economizer 7 after the heat of the refrigerant suction main road of bypass
Enter refrigeration compressor 1, the refrigerant of main road enters heat exchanger 3 and carbon dioxide is freezed.
Working method is：Carbon dioxide enters the heat exchanger 3 of stainless steel shell and tube and refrigerant carries out heat exchange, from
And making carbon dioxide condensing, refrigerant circulates in refrigeration systems, and refrigeration compressor 1 is to pump out refrigerant out of heat exchanger 3
Steam is simultaneously compressed to it, continuously absorbs heat and cold out of stainless steel tubular heat exchanger 3 in phase transition process
Heat is released in condenser 4, so as to realize refrigeration purpose, is adjusted by heating power expansion valve, reducing pressure by regulating flow.Carry out condenser 4
High pressure liquid refrigerant be divided into two parts before economizer 7 is entered, fraction (bypass) absorbs big portion by throttling cooling
Divide the heat of (main road), so that the refrigerant temperature of main road reduces to form subcooled liquid.The supercooling refrigerant of main road passes through master
Expansion valve directly enters heat exchanger 3 and freezed, and the refrigerant of bypass is then by the interface of economizer 7, reenter refrigeration compressor 1 after
Continuous compression, into circulation, the method for operation of economizer 7 improves refrigerating capacity and refrigerating efficiency.The oily cyclic system of refrigeration compressor 1
System mainly has the parts such as oil eliminator 2, oil cooler 5, and refrigerant and lubricating oil enter oil eliminator 2, ensure lubricating oil and system
Cryogen is sufficiently separated, and lubricating oil enters oil cooler 5, reduces the temperature that lubricating oil enters before refrigeration compressor 1.
PLC control system is used in the unit of above-mentioned embodiment, band text display can consersion unit operation directly perceived
State, defect content（Such as refrigerant high pressure, refrigerant low pressure, power phase failure）Deng.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to
This, the utility model can be used on similar product, and any those skilled in the art is in field of the present utility model, institute
