Abstract
The utility model relates to a modular dual-system refrigeration unit for refrigeration transport, which is designed for solving the problems that the unit can not be maintained and cause losses as which is in failure. The utility model is characterized in that: a compressor, an evaporator, a condenser, a cooling accessory and an engine are arranged on a frame; the condenser is arranged on the top of the frontage of the frame; the evaporator is arranged at the back of frame which relatives to the condenser; two engines are positioned at the lower part of the frame; two compressors are arranged on the central section of the frame and are driven by an engine respectively; two independent circulation pipelines are arranged inside the evaporator and the condenser, and each compressor is connected with an independent circulation pipeline of the evaporator and the condenser. The downtime and failure rate of the refrigeration unit is decreased to 1 / 40000 from the 0.5 percent of the single refrigeration system. The refrigeration unit can implement refrigeration and heating to the goods in the +- 40 DEG C environmental temperature range, and the temperature of the goods can be kept between -24 DEG C to +14 DEG C.
Description
The utility model relates to a kind of air temperature modification device, the modular dual system refrigerating unit that specifically a kind of refrigerated transport is used.
At present, refrigerated transport is made by single refrigeration system with refrigerating unit, compressor, evaporator, condenser, refrigeration annex and engine installation (as driving engine) etc. promptly are installed on frame, compressor is by engine installation drive work, from evaporator, suck refrigerant vapour, enter condenser after the compression, behind forced cooling, become liquid, enter liquid receiver, after some valve regulation and control throttlings, enter evaporator again.Liquid refrigerant absorbs the heat of air in the freight hold and vaporizes, and is sucked by compressor again, goes round and begins again, thereby reaches the purpose of continuous cooling.In transportation, after unit breaks down, can not in time be keeped in repair, and can only be shut down, the freight hold temperature rises, and causes goods damage.Annual fault owing to the refrigerating unit appearance, it all is very big making the expense of freight department's reparations loss of goods.
The purpose of this utility model just provides a kind of refrigerated transport special cell formula dual system refrigerating unit of high reliability, to reduce equipment failure rate, reduces the generation of goods damage.
The purpose of this utility model is achieved in that modular dual system refrigerating unit is that compressor, evaporator, condenser, refrigeration annex and driving engine are installed on frame, condenser is arranged on the front upper of frame, evaporator is arranged on the frame relative with condenser behind, in frame lower two driving engines are housed, at central rack two compressors are housed, and each is driven by a driving engine, two independent loops pipelines respectively are housed in evaporator and condenser, and each compressor is connected with an independent loops pipeline in the condenser with evaporator respectively.
Design philosophy of the present utility model is exactly to utilize cover evaporator of one in the refrigerating unit and condenser, the separate fridge equipment of two covers is set, a cover is when fault occurring therein, but another set of fridge equipment normal operation does not still occur goods damage to guarantee goods before unit obtains maintenance.Through design, experiment and measuring and calculating, the machine halt trouble incidence of this refrigerating unit drops to 1/40000 by 5 ‰ of original single refrigeration system unit, and unit reliability is greatly improved.Because the two cover shared evaporator of refrigeration system and condensers of this unit, so it is different from the simple superposition of two cover refrigeration systems.The mode of this shared evaporator and condenser owing to work simultaneously, is replenished mutually, has reduced device volume, can satisfy the requirement that conveying arrangement takes up room to refrigerating unit.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a Facad structure scheme drawing of the present utility model.
Fig. 2 is a side direction structural representation of the present utility model.
Fig. 3 is the lateral plan that two refrigeration system circulation lines are arranged in evaporator, the condenser.
As shown in Figure 2, in the front upper of square frame shape frame 1 condenser 14 of built-in two independent loops pipelines is housed, there are door assembly 2 protection the outside.Be fixed with the evaporator 9 of built-in two independent loops pipelines by adapter plate 11 at the back side of frame 1, insulation cladding 12 separates evaporation section and condensation portion.Among Fig. 1, two independently propulsion source driving engines 6,7 are housed in frame 1 bottom, two compressors were located at frame 1 middle part in 5,8 minutes, each compressor by the driving engine of its underpart by belt transmission drive work, each compressor also is connected with an independent loops pipeline in the condenser with evaporator respectively, connect again with two cover refrigeration annexes, promptly constitute two independently refrigeration system devices.
As shown in Figure 3, two the independent loops pipelines 16,17 in the evaporator 9 of this unit are between the upper and lower every, staggered form, and wherein the pipeline of fine line is a circulation line 16, and the pipeline of heavy line is another circulation line 17.Each circulation line joins by connecting copper pipe and a compressor.This two shared evaporators of refrigeration system and structure of condenser form not only meet transportation and take requirement with the volume of refrigerating apparatus, and the dual system co-operation compares with original single system refrigerating unit, and main economic and technical indices all is significantly improved.Through the experiment test contrast, can reach 8.7w/kg by worst cold case unit weight refrigerating capacity, improved 65%, the unit volume refrigerating capacity can reach 3068w/m
3, improved 90%.Because unit has powerful high temperature cold, is applicable to the occasion of precooling deficiency more, and when worst cold case, also can be by single refrigeration system work, to save the energy.
As shown in Figure 1 and Figure 2, two pairs of evaporation fans 10 and condensation fan 13 are housed on this unit, the every pair of evaporation fan and condensation fan connect a transmission shaft 15 altogether, two transmission shafts connect the gear case 4 that is positioned at central rack altogether by belt transmission, and gear case 4 joins with two driving engines 6,7 respectively by two power-transfer clutchs and the belt transmission at two ends.Adopt the coaxial ways of connecting of evaporation fan and condensation fan, and the driving of passing through driving engine, power-transfer clutch and gear case, saved blower motor, dwindled blower fan and taken up room, so the volume weight of more original two the single refrigeration system units of the volume weight of this unit obviously reduces.
Among Fig. 1, on frame 1, also be equiped with control housing 3, be used for the usefulness of the detection maintenance of unit, be furnished with the remote control electrical control cabinet in addition, utilize the automatic guidance of microcomputer controller realization difference in functionalitys such as this unit refrigeration, heating and defrostings.This unit can freeze to goods in ± 40 ℃ ambient temperature range or heat, and keeps the freight hold temperature between-24 ℃～+ 14 ℃, and this unit can be used for mechanically refrigerated truck and highway refrigerated semitrailer.
