Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1, a kind of high energy efficiency centrifugal refrigerating device, including centrifugal compressor 1, condenser 2, tonifying Qi section Energy device 3, downward film evaporator 4, oil pump 5, oil strainer 6, oil cooler 7, low fuel tank 10 and device for drying and filtering 20, centrifugal pressure Contracting machine 1 connects condenser 2, and the bottom of condenser 2 connection device for drying and filtering 20, device for drying and filtering 20 connects oil cooler 7, and oil cooling is but The left side of device 7 connection oil strainer 6, the connection centrifugal compressor 1 of oil strainer 6, the connection oil pump 5 of centrifugal compressor 1, oil pump 5 It is connected to the right side of oil cooler 7, the connection downward film evaporator 4 of oil cooler 7, the connection jet pump 11 of centrifugal compressor 1, injection Pump 11 connects low fuel tank 10, and downward film evaporator 4 connects jet pump 11 by stop valve 12, and condenser 2 is connected by jet pump 11 Connect low fuel tank 10, the connection tonifying Qi of centrifugal compressor 1 energy-saving appliance 3, the first angle valve 18 of the bottom of condenser 2 connection, the first angle valve 18 Connect the first visor 17, the first visor 17 connects the first electric expansion valve 16, the connection tonifying Qi energy-saving appliance of the first electric expansion valve 16 3, tonifying Qi energy-saving appliance 3 connects the second visor 15, and the second visor 15 connects the second electric expansion valve 14, and the second electric expansion valve 14 connects Connect the second angle valve 13, the connection downward film evaporator 4 of the second angle valve 13.
The top of downward film evaporator 4 is connected with the safety valve 9 of liquid storage pot valve 8 and first.
The top of condenser 2 is connected with the second safety valve 19.
Centrifugal compressor 1 connects downward film evaporator 4.
The component of centrifugal compressor mainly includes front and back stages impeller, diffuser, bend, return channel and spiral case.Impeller It is critical piece, refrigerant gas are done work by impeller, makes gas obtain speed and energy.Impeller adopts backward leaning vane formula leaf Wheel, the leaf road of impeller is longer, and blade flexibility is less, and leaf road sectional area gradually increases, and gas is not easy when Ye Daonei flows The separation in boundary layer is produced, it is possible to reduce the gas flow loss in impeller, so as to improve the efficiency of compressor.Diffuser is main The conversion of gas energy form is realized, flow velocity after diffuser is entered from the impeller gas with larger speed out and is reduced, moved Pressure energy can be effectively converted into.Second level compressional zone, Jing rear classes are entered from diffuser gas Jing bends out and return channel After wheel compresses, gas pressure is further improved, and gases at high pressure are pooled in spiral case, is discharged by exhaust outlet, completes whole pressure Compression process.
In this compression kind of refrigeration cycle, the compression process of first stage is the low pressure refrigerant vapor of flash-pot in future Bring prime impeller workspace into, gas does centrifugal motion under prime impeller-driven, and air velocity and pressure get a promotion.This portion The gas of lease making primary compression carries out cooling during rolling process with the flash gas from economizer, and liquid refrigerant returns to evaporation Device, gas enters second level compressional zone.The refrigerant flow of second level compressional zone is because adding the flash distillation that Economy of Intermediate Form device is produced Gas and be more than the refrigerant flow of low-pressure stage, bigger refrigerating capacity can be produced for single stage compress.It is simultaneously premenstrual The refrigerant gas of level compression have passed through cooling during rolling process before compressing into next stage, will the exhaust of low-pressure stage be cooled to Subordinate's compression is entered back into after saturated vapor under intermediate pressure, the wasted work that can make compressor exports reduction.
The above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover in the middle of right of the present utility model.
