Technical field
The utility model relates to a kind of refrigerating plant, is a kind of frozen products insulated container refrigerating plant specifically.
Background technology
There is defect in structure and the refrigeration of domestic large-scale land transportation frozen products insulated container refrigeration plant at present, cause massive losses not only to land transportation frozen products insulated container user, do not meet the energy-conserving and environment-protective of China, the policy requirements of food security, restricted to a greater extent the benign development of low-temperature transport industry yet.
Domestic large-scale land transportation refrigerated container refrigerating device has two types at present, be respectively the special frozen products insulated container refrigeration plant of refrigeration plant, surface vehicle of sea-freight frozen products insulated container, these two types of refrigeration plant defects are as follows: the refrigerating device refrigeration structural design of sea-freight frozen products insulated container is not suitable for land vehicle-mounted transport, airflow radiating is unreasonable, middle refrigeration extreme difference travels, particularly exceed in external environment condition+30 DEG C time, refrigeration is poorer, both increase energy consumption, also do not reached the requirement of low temperature goods refrigeration.The special frozen products insulated container refrigeration plant that land transport vehicle uses is unreasonable because parts structure designs, automation control inaccuracy, and fault rate is high, difficult maintenance.There is following shortcoming in the extra large cabinet refrigerated container refrigerating device that land transport vehicle uses at present: 1, condenser wind direction is designed to dry from back to front, reverse with the airflow direction producing in Vehicle Driving Cycle, cause heat radiation unreasonable, fan resistance is large, poor refrigerating efficiency, uneconomical.Though this type can be realized temperature and accurately control, refrigerating capacity is less than normal, is not suitable for domestic land transport requirement.Though 2, condenser wind direction has changed the mode of drying from front to back into, due to its compressor and driving mechanism direct-connected, cause compressor shaft gland place easily to produce freon leakage.More complicated because of belt interlinked mechanism parts, fault rate is high, difficult discovery, difficult maintenance.Difficulty realizes temperature automation and accurately controls.
Summary of the invention
The utility model for address the above problem provide a kind of rational in infrastructure, airflow direction is evenly distributed, good refrigeration effect, frozen products insulated container refrigerating plant that energy consumption is low.
The utility model for the technical scheme that technical solution problem adopts is:
A kind of frozen products insulated container refrigerating plant described in the utility model comprises support and rack-mount compressor, condenser, condensation fan, described support is provided with compressor installing rack and condenser installing rack, described condenser installing rack is positioned at the top of compressor installing rack, described compressor is fixedly mounted on compressor installing rack, and described condenser is fixedly mounted on condenser installing rack; Described condensation fan is arranged on the rear of condenser; Rear at support is provided with supplying air bin, and the upper end of described supplying air bin is provided with air inlet, and described air inlet is provided with interior evaporation fan; In in the inner chamber of supplying air bin evaporation fan below be provided with interior evaporating heat exchanger.
On support below compressor installing rack, be installed with driving mechanism, described driving mechanism comprises engine, is connected to the generator of engine output, and the output of described generator is connected to the power end of compressor.
After high before described interior evaporating heat exchanger, lowland tilts to install.
Adopt after technique scheme, frozen products insulated container refrigerating plant tool described in the utility model has the following advantages: condenser is preposition, the radiating mode of bleeding before adopting rainproof drip-proof fan word backward, identical with the airflow direction producing in Vehicle Driving Cycle, be conducive to heat radiation, reduce fan resistance, improve refrigeration, reduce energy consumption; Unique internal structure, makes inner cold wind take lower air-out endless form, makes the temperature inside the box more even, and ensures that evaporimeter is relatively clean, is more conducive to heat exchange.
Brief description of the drawings
Fig. 1 is the structure cutaway view of an embodiment of the utility model.
Detailed description of the invention
As shown in the figure, a kind of frozen products insulated container refrigerating plant described in the utility model comprises support 1 and is arranged on compressor 2, condenser 3, the condensation fan 4 on support 1, is also provided with the functional parts such as expansion valve, reservoir, device for drying and filtering, check valve, manual service valve between compressor 2 and condenser 3.Described support 1 is provided with compressor installing rack 11 and condenser installing rack 12, described condenser installing rack 12 is positioned at the top of compressor installing rack 11, described compressor 2 is fixedly mounted on compressor installing rack 11, described condenser 3 is fixedly mounted on condenser installing rack 12, condenser 3 is arranged on higher position, is conducive to heat circulation, and compressor 2 installation sites are lower, be conducive to reduce noise, improve the stability of complete machine.
Described condensation fan 4 is arranged on the rear of condenser 3; Be provided with supplying air bin 5 at the rear of support 1, the upper end of described supplying air bin 5 is provided with air inlet, and described air inlet is provided with interior evaporation fan 6; In in the inner chamber of supplying air bin 5 evaporation fan 6 below be provided with interior evaporating heat exchanger 7.After the front height of described interior evaporating heat exchanger 7, lowland tilts to install.Described interior evaporating heat exchanger 7 can be connected in parallel with condenser 3, also can be connected in series, and forms two-stage heat exchange pattern.
Extraneous air is sucked from air inlet by interior evaporation fan 6, and after interior evaporating heat exchanger 7 heat exchange, the blower fan 4 that is condensed blows to front, then with condenser 3 heat exchange, form circularly cooling.
On support 1 below compressor installing rack 11, be installed with driving mechanism 8, described driving mechanism 8 comprises engine and is connected to the generator of engine output, and the output of described generator is connected to the power end of compressor 2.Generating set underlying is integrated, has avoided vehicle retrofitting, and compressor physical life is long, and failure rate is low for ease of maintenaince, meets national communication transportation safety policy.
Above corrective measure makes full use of the high wind speed backward that surface vehicle causes in running at high speed, and reduces radiator fan pressure at expulsion, has reduced fan rotor load, has improved radiator heat-dissipation efficiency, has reduced energy consumption.Make radiator fan more durable.This scheme technology is more than environment temperature+35 DEG C time, and refrigeration comparative advantages are particularly outstanding.
In addition, in order accurately to control cryogenic temperature, can also set temperature control circuit and electric heater unit.When work, first starter-generator group is powered to refrigeration machine, and condensation fan and evaporation fan move simultaneously, and when the temperature inside the box is during higher than design temperature, compressor operating, realizes refrigerating function.Under fresh-keeping mode of operation, in the time that case inner wind outlet temperature approaches design temperature, regulate refrigerating capacity, reach the regulation temperature difference to reaching air-supply with return air temperature.Under cryogenic freezing mode of operation, be as the criterion with return air inlet temperature, need not regulate refrigerating capacity, autostop when reaching set point of temperature.When the temperature inside the box is during lower than design temperature, electric heating system is started working, during to design temperature, and autostop.
