Description
Technical field
The present invention relates to a kind of compressor of air conditioner, be especially capable of Energy Efficiency Ratio height, centrifugal compressor is successively decreased in low and life-span length the closing of noise.
Background technology
At present, known compressor of air conditioner is the core component in air-conditioning, the performance indications of its each side are to weigh the main standard that air-conditioning is good and bad, existing can be divided into reciprocating compressor according to operation principle, positive displacement compressor, centrifugal compressor etc., although it is high that traditional positive displacement gas compressor and reciprocating gas compress airtight coefficients comparison, but occur between part and part, there is very big frictional force due to inside the machine that positive displacement gas compressor and reciprocating gas compress, and a lot of energy of these frictional force losses undoubtedly, plus remaining seam loss, cause that the Energy Efficiency Ratio of positive displacement gas compressor is very low, although traditional centrifugal compressor overcomes the frictional force of various aspects, but the shortcoming that centrifugal compressor occurs in that surge, airtight coefficient is low, capacity is excessive, thus make the Energy Efficiency Ratio of air-conditioning decline, resource is caused waste.
Summary of the invention
In order to solve the problem that existing centrifugal compressor Energy Efficiency Ratio is low, noise is big and airtight coefficient is low, the present invention provides closing to successively decrease centrifugal compressor, this closing is successively decreased the shortcoming that centrifugal compressor overcomes traditional compressor, achieve adaptation Energy Efficiency Ratio high (up to 16-30), operating voltage range width (90V~260V), airtight coefficient high (more than 96%), noise low (below 30db), energy gas transmission continuously, save the energy.
The technical solution adopted for the present invention to solve the technical problems is: this closing centrifugal compressor that successively decreases includes: centrifugal wheel disc, wheel pan arrest, a cylinder, air inlet pipe, radiating tube, a end cap, bolt hole, housing, runner gas outlet, spring, a bearing, main shaft, rotor, stator, b cylinder, exhaustor, b end cap, b bearing, binding post, wiring, rosette, runner, this closing centrifugal compressor that successively decreases is provided with the centrifugal wheel disc of a ring discoid, centrifugal wheel disc is uniformly provided with bolt hole, to facilitate connecting bolt to use;Centrifugal wheel disc is evenly distributed with the runner being gradually reduced degression type from the center of circle to circumference, the sectional area of runner longitudinal direction every bit is to carry out computing according to the thermodynamic behaviour being used in this compressor coolant and determined by test of many times, gas is progressively compressed by runner under the drive of centrifugal wheel disc, this addresses the problem the surge phenomenon of transmission centrifugal compressor; Centrifugal wheel disc is connected with wheel pan arrest by bolt, the pan arrest body that wheel pan arrest periphery has multiple runner gas outlet, center is perforate, and extended end is hollow axle; Centrifugal wheel disc one side is connected with wheel pan arrest by bolt, and another side is connected with a end cap super close distance micro chink precision-fit by a cylinder, and the center of a end cap is connected to air inlet pipe, and air inlet pipe aligns centrifugal wheel disk center opening; The side of air inlet pipe is connected with the b end cap super close distance micro chink precision-fit of housing by radiating tube, and b end cap outside is respectively equipped with a rosette and exhaustor, and b cover internal is connected with wheel pan arrest super close distance micro chink precision-fit by b cylinder; Connecting centrally through spring, a bearing, b bearing, main shaft super close distance micro chink precision-fit of b cylinder and a cylinder, main shaft is connected to spring through the hollow axle of wheel pan arrest; It is sequentially provided with rotor, stator and housing outside the hollow axle of wheel pan arrest; Stator is connected with the binding post in rosette by wiring; The two ends of housing are connected with a end cap and b end cap super close distance micro chink precision-fit respectively; During use, gas enters centrifugal wheel disc by air inlet pipe, under the drive of wheel pallet, gas progressively compresses in the runner effect of centrifugal wheel disc, the principle utilizing cylinder and the centrifugal wheel disc closing degression type carry out super close distance micro chink connection, to reach to stop return-air, high airtight coefficient, purpose without surge and little capacity, while raising compressor operating efficiency, compressor own wt can also be alleviated, reduce volume, reduce production cost.
Beneficial effects of the present invention: this closing is successively decreased the shortcoming that centrifugal compressor overcomes traditional compressor, owing to almost without mechanical friction, reducing operating mode standard without lubricating oil to improve cold and hot exchange rate, so very energy-conservation, Energy Efficiency Ratio rises to more than 16 from the 8.6 of drive technology; Simultaneously because the sectional area of runner successively decreases gradually from the center of circle to circumference, have also been obtained volume reduction compression, then flow out from runner gas outlet while air current flow, the pressure ratio altitude chamber of runner gas outlet is high, does not have backflow phenomenon, thus having stopped surge; All being connected by super close distance micro chink precision-fit plus the present invention, altitude chamber inner high voltage gas only has minimal amount of string back into trachea, makes airtight coefficient rise to more than 96% from traditional 50%~70%; Also having accomplished that structure is more traditional simpler, volume is little, lightweight, and production cost is low, produces in batches; The adaptation voltage range also making compressor has expanded 90V~260V to; Improve the stability of compressor, extend service life, saved the energy, be a kind of great technological break-through.
