Accompanying drawing explanation
Fig. 1 structural principle schematic diagram of the present utility model.
The specific embodiment
Shown in Fig. 1, for a kind of single stage compress cryogenic refrigerating system, comprise compressor 1, the input of described compressor 1 is connected with the output of the first gas-liquid separator 17, and its output is connected with condenser 2; The output of described condenser 2 is connected with the input of the second gas-liquid separator 3, the first output of described the second gas-liquid separator 3 is connected to the first input end of the first heat exchanger 4 by the first expansion valve 6, the first output of described the first heat exchanger 4 is connected to the input of described the first gas-liquid separator 17;
The second output of described the second gas-liquid separator 3 is connected with the second input of the first heat exchanger 4, the second output of described the first heat exchanger 4 is connected to the first input end of the second heat exchanger 5 by the second expansion valve 7, the first output of described the second heat exchanger 5 is connected to the input of described the first gas-liquid separator 17; In single stage compress cryogenic refrigerating system of the present utility model, also comprise low temperature refrigerating medium container 16, its input is connected with the second output of described the second heat exchanger 5, and its output is connected to the second input of described the second heat exchanger 5 by coolant pump 15.
Wherein, the input of described compressor 1 is provided with inlet valve 9, and its output is provided with air bleeding valve 10; On described inlet valve 9, be provided with low-pressure meter 12, on described air bleeding valve 10, be provided with high pressure gauge 13, between described low-pressure meter 12 and described high pressure gauge 13, be connected with high-low pressure relay 11.In addition, on described condenser 1, can also be provided with ventilating fan 14, can accelerate so cooling.
Its operation principle is as follows:
During compressor 1 work, first the mixed refrigerant vapor of HTHP enters into carries out cooling and condensation process in condenser 2.Wherein, high temperature refrigerant A in the mixed refrigerant vapor of HTHP is condensed into liquid and enters the second gas-liquid separator 3, and become low pressure liquid through the first expansion valve 6 reducing pressure by regulating flows, then in the first heat exchanger 4, carry out evaporation endothermic, make the second heat exchanger 4 become low temperature environment, then the steam producing, after the first gas-liquid separator 17 separation, is reuptaked compression by compressor 1 again.
Meanwhile, due to the low-temperature refrigerant B in the mixed refrigerant vapor of HTHP, because do not meet condensing condition in condenser 2, although its pressure is promoted, low-temperature refrigerant B can not be condensed into liquid in condenser 2.Like this, the low-temperature refrigerant B after boosting, after the separation of the second gas-liquid separator 3, enters the second heat exchanger 4 and is condensed into highly pressurised liquid; Highly pressurised liquid, by after the second expansion valve 7 reducing pressure by regulating flows, becomes low pressure liquid, and then enters the interior evaporation endothermic of the second heat exchanger 5.Now, refrigerating medium in low temperature refrigerating medium container 16 is by the effect of coolant pump 15, enter in the second heat exchanger 5 and the generation of the low-temperature refrigerant B after step-down heat exchange, obtain-40 ℃ of following low-temperature refrigerants, the steam producing after the low-temperature refrigerant B obtaining evaporates, absorbs heat in the second heat exchanger 5, equally also, through the first gas-liquid separator 8 separation, finally by compressor 1, reuptaked compression again, so iterative cycles.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
