Description
Technical field
The utility model relates to a kind of off-premises station of detachable air conditioner, particularly is applicable to the architecture advances technology of miniaturized outdoor unit casing.
Background technology
In order to control product cost, to enhance product performance, the design of the off-premises station of detachable air conditioner need be taken all factors into consideration from each side such as cost, quality, performances.
Existing application is in the single-cooling type of refrigerating capacity 2300～3200W or the off-premises station of refrigerating and heating type detachable air conditioner, and commonly used have economical small box and two kinds of specifications of the big casing of heavy duty detergent.Typical small box is of a size of 700 * 225 * 500 millimeters, because the restriction of physical dimension, can only the in line or single curved row's condenser of adapted list.About 490 millimeters of the in line condenser copper tube length of adapted list, the condenser fin area is about 6.0 square metres; About 650 millimeters of the curved row of adapted list condenser copper tube length of run, the condenser fin area is about 8.1 square metres.Calculate according to air-cooled heat exchange efficiency, the outside exchange capability of heat is lower, and refrigerating efficiency is low when being applied to the air-conditioner of 2600～3200W refrigerating capacity.A kind of design adopts thickening chamber body body, be of a size of 660 * 255 * 430 millimeters, the technical scheme of the two in line condensers of adapted can satisfy the needs of outside heat exchange area, but this scheme condenser area and cost rise about 50% and significantly increase cost, and the outside noise is higher.The design of some small box adopts the cancellation central dividing plate dwindling the scheme of box sizes, but causes the off-premises station noise very high owing to compressor is not closed.
Typical big box sizes is 760 * 255 * 540 millimeters, about 590 millimeters of the in line condenser copper tube length of adapted list, and the condenser fin area is about 8.1 square metres; About 760 millimeters of the curved row of adapted list condenser copper tube length of run, the condenser fin area is about 10.6 square metres.The outside exchange capability of heat is higher, comparatively is fit to the air-conditioner that refrigerating capacity is big, refrigerating efficiency is high and uses.But be applied to 2300～2600W refrigerating capacity, the condenser area was bigger than normal when refrigerating efficiency was about 2.6～2.8 air-conditioner, the cost of casing sheet metal component and condenser is all higher.In addition, the Package size of big casing is corresponding bigger, and the vanning amount when using the container transportation is low, and cost of transportation is higher during outlet.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of design of miniaturized outdoor unit casing is provided, and when guaranteeing the refrigerating efficiency of air-conditioner, reduces the volume and weight of off-premises station.That is to say, a kind of casing of air-conditioner miniaturized outdoor unit is provided, make its can adapted F7 millimeter copper pipe the condenser of single or two-row structure, again can adapted F9.52 millimeter copper pipe the condenser of single or two-row structure, then can realize multiple combinations such as outdoor condenser area 6.5,8.7,13.0,17.6, thereby satisfy the different needs of common efficiency level 2300～3200W refrigerating capacity air-conditioner and high energy efficiency level 2300～2600W refrigerating capacity air-conditioner, thereby realize the generalization and the miniaturization of products of different specifications.Simultaneously, the exploitation of this off-premises station casing also takes into account and reduces casing cost, cost of transportation, off-premises station noise that the vanning amount reflected and improve the aspects such as design flexibility of using different compressors.
Therefore, the exploitation of this off-premises station casing, at first to calculate to determine the demand of the air-conditioner of different refrigerating capacitys and refrigerating efficiency demand, and obtain the required copper pipe radical of various condenser forms by the different Cu length of tube in conjunction with the condenser that main flow condenser fin form and tube pitch propose F7 millimeter or F9.52 millimeter copper pipe, single or double totally 4 kinds of compound modes by theory to the condenser heat transfer area.This moment, the fin area of fractional distilling tube form may satisfy the design needs just, and then the possibility surplus is bigger for the fin area of fractional distilling tube form.Select different copper pipe lengths of run, when satisfying F7 millimeter or F9.52 millimeter copper pipe, single or double totally 4 kinds of condenser heat exchange area demands simultaneously, the ratio of the condenser fin area of actual design type selecting and minimum essential requirement condenser fin area is called the heat exchange area design margin.By being variable with the copper pipe length of run, the copper pipe when satisfying required heat exchange area separately with four kinds of condenser forms and the weighted average of aluminium foil cost are that object function is optimized, and can obtain several groups of suitable copper pipe length and pairing condenser fin areas thereof.Performance level when using on actual air-conditioner by heat exchanger heat transfer experimental verification aforementioned calculation result again, and heat exchanging device length is adjusted thus.At last, in conjunction with the air-conditioner vanning amount that the size measuring and calculating band of high cube container container peace cabinet container is packed,, and verified by experiment with the definite optimum heat exchanger and the design size of this miniaturized outdoor unit casing.
The part result of calculation of this technology is as shown in table 1.At first determined the off-premises station height, the radical when obtaining this off-premises station adapted F7 millimeter copper pipe simultaneously according to F9.52 millimeter radical.A, pitch of fins wide and tube pitch for the heat exchanger copper pipe of determining and fin form, sheet, and with the air quantity of existing product as test basis, measured the heat transfer coefficient of heat exchanger by heat exchanger performance test.Then, according to the common efficiency level of 23,26,32 machines measuring and calculating required minimum heat exchange area when the room type air regulator GB condition, heat exchanger can select that F9.52 is double, F9.52 is single, F7 is double, the single four kinds of forms of F7 during actual match, with heat exchange area the most approaching and greater than the heat exchanger form of the minimum heat exchange area of theoretical calculation as test basis, by the feasibility of this heat exchange scheme of analysis of experiments.If result of the test can not satisfy the performance requirement of air-conditioner, then need to use instead large-area slightly heat exchanger form.Heat exchanger area under the heat exchanger form that will confirm by test is called the heat exchange surplus with the ratio of the minimum heat exchange area of theoretical calculation, and the overall efficiency of more little then heat exchanger of heat exchange surplus and casing is high more.Calculate the weighting heat exchange surplus of casing in the production and marketing ratio of 23 machines 25%, 26 machines 40% and 35 machines 35%.As can be seen from Table 1, different body structures and corresponding heat exchanger form thereof, the heat exchange surplus when being used for different type of machines is different, and the weighting heat exchange surplus minimum of the outdoor casing of compatible 9 F9.52 millimeter copper pipes and 11 F7 millimeter copper pipes.According to similar method, by can further determine the optimum length and the thickness of outdoor casing to the multiple-objection optimization of weighting heat exchange surplus and vanning amount according to the heat exchanger length of run.
