| titleOfInvention | Dual refrigerant forced circulation refrigeration unit |
| abstract | The present invention uses the secondary refrigerant R-22 gas as the primary refrigerant R-23 gas to maintain the refrigeration temperature at a very low level through heat exchange between two refrigerants circulated along different paths. The present invention relates to a dual refrigerant forced circulation refrigerating device that performs cooling by circulating the R-22 gas after cooling to an extremely low temperature of 75 ° C. n An intercooler 12 supplying a refrigerant gas in a gaseous state to the condenser 13 by lowering the pressure of the primary refrigerant from the compressor 11; A first heat exchanger (30) for completely liquefying the primary refrigerant and raising the temperature of the secondary refrigerant through heat exchange between the primary refrigerant and the secondary refrigerant from the condenser (13); A high pressure receiver 14 for temporarily storing the primary refrigerant from the first heat exchange unit 30 and circulating only the primary refrigerant in the liquid phase; A second heat exchange part 35 for cooling the secondary refrigerant to cryogenic temperature by using latent heat of evaporation due to vaporization of the primary refrigerant; A gas injector 15 provided at an inlet end of the second heat exchanger 35 to inject a liquid primary refrigerant from the high pressure receiver 14 into the second heat exchanger; A low pressure receiver 20 in which a low temperature secondary refrigerant from the second heat exchange part 35 is stored; A first liquid pump (21) for supplying a liquid secondary coolant to the first heat exchange part (30) from a lower end of the low pressure receiver (20); An evaporator coil 25 for performing a freezing operation using latent heat of evaporation according to vaporization of the secondary refrigerant of the low pressure receiver 20; And a second liquid pump 23 for supplying a liquid secondary coolant to the evaporator coil 25 from a lower end of the low pressure receiver 20. n Therefore, the secondary refrigerant can be cooled to cryogenic temperature only by circulating the secondary refrigerant using a liquid pump without using a separate compressor as well as lowering the freezing temperature. n n Refrigerating unit, refrigerant, forced circulation, compressor, liquid pump, R-22, R-23, cryogenic |
