Description
?
[technical field]
The present invention relates to a kind of linear compressor, particularly relate to a kind of compressor of many power stacks;
The invention still further relates to a kind of chiller plant, specifically a kind of chiller plant that adopts the compressor of many power stacks.
[background technique]
According to investigations and patent retrieval, existing linear compressor great majority are moving-magnetic types, moving coil, three kinds of moving-iron type, their common feature is all the product that is based upon on existing theoretical foundation and increases resonance section, namely electric rotating machine is launched in the magnetic field of linear electric motor and approximate being interpreted as of the characteristics of motion, and thinks that both working principles are identical, that is to say, linear compressor its moving direction the same as rotary compressor is to carry out along the tangent direction of the magnetic line of force.Add on this basis upper spring resonance and develop various structure shapes and form linear compressor.Although the performance of linear compressor should have larger advantage than traditional rotary compressor in theory, because linear compressor has not had the driving mechanisms such as bent axle, make energy consumption, volumes etc. ought to reduce, but in actual applications, its efficiency is compared and is not had much raisings with traditional rotary compressor, go through a century although cause linear compressor, but still do not obtain much breakthroughs, even it would be better rotary compressor aspect some, such as in the control of stroke, linear compressor is not as rotary compressor, also not too large difference on volume, and the wearing and tearing of compressor when work are larger.
In addition, the stroke of moving coil linear compressor is shorter, and its winding wire is fragile and cause often breaking down; And the mover of moving-magnetic linear compressor is heavier, cause the resonant springs elasticity of needs larger, this but makes resonance wayward, thereby makes the actual compression effectiveness effect on deviation theory far away; And the moving-iron type linear compressor very easily produces radial force, cause piston serious friction cylinder wall.All these shortcomings, be all because in theory this mode of rotation motion to linear is not suitable for to linear compressor, makes current linear compressor be difficult to be applied widely always.
Moreover, spacing most employing step-by-step linear electric motor of conventional linear compressor, or in cylinder mounting spring, or displacement probe is installed in cylinder and is controlled the method such as compressor stroke by circuit and realize.These methods of controlling stroke are unsatisfactory.By above elaboration, be it seems, linear compressor will really be brought into play its advantage must be had and be different from traditional new theory and new technology.
Chiller plant comprises refrigerator and air conditioner freezer etc., and the main refrigeration modes of these equipment has steam compression type all the time, and the semiconductor cooling sheet is absorption etc., and wherein steam compression type refrigeration is because its technology is more ripe, and efficiency is higher and most widely used.And steam compression type has the several types compressor: the rotary crankshaft piston type, rotary, eddy type, Linear piston type etc.Wherein first three plants mode technology comparative maturity, although Linear piston type efficiency in theory can be than large in first three but technology is also little ripe, and efficiency is unobviously especially large, greatly about about 20-30%, but be exactly that these 20-30% scientific and technical personnel have still dropped into huge effort to linear compressor.The advantage of existing linear compressor is that structure is relatively simple, and the loss caused because of transmission reduces.But existing linear compressor is to be based upon the product drawn on rotary compressor working principle basis, namely the motor of linear compressor is that the rotary compressor motor launches.Therefore so both do not have much differences on principle, also being doomed existing linear compressor equally has larger limitation with rotary compressor, so break through because the efficiency that energy is conservation improves limited being difficult to.
It is that end to end magnetic pole formation loop forms that the magnetic field of electric rotating machine can be regarded as, so not very good breakthrough.And linear electric motor can make head and the tail disjunct; When work done produces positive and negative two kinds of energy simultaneously, if these two kinds of energy can be used altogether, institute's work will be larger than initial input energy so.
In order to overcome above-mentioned technical deficiency, the compressor of many power stacks that I invent is equally switched on to electromagnet, N and S will be produced in the electromagnet two ends, the energy provided with two utmost points of this positive and a negative output of doing work and superpose, and this is that traditional compressor and existing linear compressor can not have.Obviously, the Compressor Technology of many power stacks that I am invented will have important breakthrough for the efficiency of chiller plant, and this is also desirable.At present the situation of refrigerating appliance is multiplex rotary compressor on air-conditioning, and the slightly large scroll compressor of using, at the multiplex piston compressor of commercialization and refrigerator field.

The present invention compares produced beneficial effect with background technique:
The present invention has adopted above-mentioned technological scheme, and the principle of design is fully different from traditional linear compressor; And bring following advantage: 1, under traditional theory, the motion of linear compressor is to carry out along the tangent direction of the magnetic line of force, and the design's principle is to move to carry out along magnetic field axis, and the power that two magnetic poles produce can superpose.Although the magnetic force at magnetic pole two ends can reduce along with distance, after two magnetic force stacks, can better overcome this shortcoming.The thrust that the magnetic field obtained while for cylinder, being placed in the situation piston compression at moving element two ends produces is the magnetic force addition at the two poles of the earth, the power that the twice magnetic pole produces.Be placed in the situation of moving element one end for cylinder, the thrust that acts on when piston makes piston compression the magnetic field generation obtained by spring energy-storage is the twice of the magnetic force addition at the two poles of the earth, i.e. four times of power that magnetic pole produces.Conclusion can be inferred thus, and this design will make the efficiency of linear compressor have than quantum jump, and this is that conventional linear compressor is incomparable.Because conventional linear compressor is along magnetic line of force tangential motion, and there is no so much power stack.
2,, because the relative movement between moving element and stator does not have tangent condition, namely moving element does not have the condition tangent with the magnetic line of force, so copper loss and iron loss will easily better be controlled.
3, because the design's principle is fairly simple, but can obtain than high thrust, so the volume of newly-designed linear compressor can be done very littlely, low powerly accomplish that the syringe needle size should be out of question, powerful power is large, and volume is little.
4, because the motion of piston is moved along cylinder axis substantially, so easily accomplish without the oil operation.
5, because newly-designed linear compressor has several power stacks, thus larger stroke can be obtained under appropriate design, thus improve Energy Efficiency Ratio, because compressor work is only relevant with cylinder diameter and irrelevant with stroke.
6, the motion due to newly-designed compressor has several power additions, so easily obtain large starting torque, thereby make to compress the condition that functional adaptation is larger, changes, and makes to obtain in working life of compressor larger raising.
7,, due to the spacing gas spring that is equivalent to of piston, belong to flexible and slow down, so the noise of new compressor will easily be effectively controlled.
8, the invention still further relates to a kind of chiller plant, have energy-efficiently, compare traditional chiller plant and greatly improved power stage, the acting in conjunction of energy-saving safe and the stack of many power, be a kind of technical superior product.
