The specific embodiment
Flat fast-freezer refrigerating plant, comprise cold drawing assembly 1, lower cold drawing assembly 2, compressor 12, condenser 5 and reservoir 7, described compressor 12 has two imports and two outlets for split-compressor, the first outlet is connected with condenser 5 by main line a, described main line a can be connected with precooling pipeline b before being communicated with condenser 5, and precooling pipeline b is unidirectional to be communicated with main line a after entering lower cold drawing assembly 2; Described main line a can be connected with the defrosting pipeline c that enters upper cold drawing assembly 1 and lower cold drawing assembly 2, and described defrosting pipeline c is communicated with end and is provided with the first magnetic valve 4a with main line a; Condenser 5 is connected with reservoir 7 by pipeline, and pressure measuring valve 6 and the second magnetic valve 4b are installed on pipeline, and the drying filter 3 of reservoir 7 is connected with the first import of compressor 12; The second outlet of compressor 12 connects refrigeration pipe d, after refrigeration pipe d branch, enter respectively cold drawing assembly 1 and lower cold drawing assembly 2, refrigeration magnetic valve 17 and expansion valve 16 are installed on the branch's refrigeration pipe on entering before cold drawing assembly 1 or lower cold drawing assembly 2, the pipeline that goes out upper cold drawing assembly 1 pipeline and lower cold drawing assembly 2 converges rear connection gas-liquid separator 18, and gas-liquid separator 18 is connected with the second import of compressor 12.
The pipeline that goes out upper cold drawing assembly 1 pipeline and lower cold drawing assembly 2 converges afterwards and is connected gas-liquid separator 18 by the 3rd magnetic valve 20 or pressure-regulating valve 19.During refrigeration, magnetic valve 20 is opened, because pressure-regulating valve 19 has back pressure, cold-producing medium all refluxes through magnetic valve 22 without pressure-regulating valve 19, during defrosting, magnetic valve 20 cuts out, and cold-producing medium refluxes through pressure-regulating valve 19, and pressure-regulating valve 19 can be controlled the pressure of the cold-producing medium of gas-liquid mixed state in the reasonable scope.
Described main line a is provided with muffler 9 and vibration damping pipe 8 at first port of export.In muffler 9, there is labyrinth type noise reduction passage, can eliminate high pressure liquid stream impact noise.The pipeline vibration that vibration damping pipe 8 causes for eliminating liquid flow impact, avoids generation of vibration noise and pipeline fatigue fracture.
At device for drying and filtering 3 and 12, compressor, be connected with and show liquid mirror 10.Show that liquid mirror 10 can observe easily the capacity of compressor refrigerant in compressor start running, compressor itself is also furnished with the liquid of showing window, also observable refrigerant charge.
What the present embodiment was illustrated is that upper cold drawing assembly is portable plate, the Flat fast-freezer that lower cold drawing assembly is fixed head, for guaranteeing the smooth and easy of portable plate motion, Hou Yi branch of refrigeration pipe d branch enters upper cold drawing assembly 1 through flexible steel in flat section tubing c15, another branch enters lower cold drawing assembly 2, go out upper cold drawing assembly 1 pipeline and converge through the pipeline of flexible steel in flat section tubing a13 and lower cold drawing assembly 2, defrosting pipeline c is connected with upper cold drawing assembly 1 by flexible steel in flat section tubing b14.If Flat fast-freezer is that upper cold drawing assembly 1 is fixing, lower cold drawing assembly 2 activities descend cold drawing assembly to adopt flexible steel in flat section tubing to be connected with pipeline.
As shown in Figure 4, the compressor 12 of Flat fast-freezer adapted is split-compressor to operation principle of the present utility model, has two imports and two outlets.While starting refrigeration program, compressor 12 is first by refrigerant compression, and the liquid high temperature refrigerant after compression enters condenser 5 via muffler 9 and vibration damping pipe 8, and now the first magnetic valve 4a of condenser 5 upper ends is in closed condition.When ambient temperature is higher, open hand sluice valve 11, liquid high temperature refrigerant after compression enters lower cold drawing assembly 2 inside, after lower cold drawing assembly 2 precoolings, through check valve 21a, get back to again main line, this bypass circuit is called pre-cooling cycle, be foregoing precooling pipeline b, utilize the precooling effect of lower cold drawing assembly 2, reduce the temperature of the liquid high temperature refrigerant after compression, to guarantee through the condensed refrigerant temperature of condenser 5 in the reasonable scope.Cold-producing medium is after condenser 5 is cooling, through pressure measuring valve 6 and the second magnetic valve 4b, enter reservoir 7, then drying filter 3 and liquid-sighting glass 10 feed back to compressor 12, cold-producing medium is after compressor 12 second-compressed, by outlet, through refrigeration magnetic valve 17a, expansion valve 16a and flexible steel in flat section tubing c15, be transported to upper cold drawing assembly 1, through refrigeration magnetic valve 17b, expansion valve 16b, be transported to lower cold drawing assembly 2.Together with the cold-producing medium of upper cold drawing assembly 1 of flowing through converges to the cold-producing medium of the lower cold drawing assembly 2 of flowing through through flexible steel in flat section tubing a13, now cold-producing medium is gas-liquid mixed state, through pressure-regulating valve 19, enter gas-liquid separator 18, gaseous refrigerant after separation feeds back to again compressor 12, completes a kind of refrigeration cycle.
After Flat fast-freezer is finished the work, can start defrosting program, now compressor 12 is first by refrigerant compression, liquid high temperature refrigerant after compression is via muffler 9, vibration damping pipe 8, the first magnetic valve 4a of condenser 5 upper ends, check valve 21b enters lower cold drawing assembly 2, through the first magnetic valve 4a, flexible steel in flat section tubing b14, check valve 21c enters cold drawing assembly 1, now the second magnetic valve 4b of condenser 5 lower ends is in closed condition, liquid high temperature refrigerant temperature up to 60 ℃ to 70 ℃, can melt fast and dry the frost that condenses in cold drawing assembly 1 and lower cold drawing assembly 2 working surfaces, complete after defrosting program, compressor 12 quits work automatically.
