Description
Technical field
The utility model relates to a kind of rotary compressor, particularly a kind of variable-displacement rotary compressor.
Background technique
Air conditioner is generally used for making room temperature and/or humidity to remain on setting value, and the interior space is remained on comfort conditions.Air conditioner generally comprises a cover refrigeration system.This refrigeration system comprises: compressor is used for compressed refrigerant; Condenser is used for the compressed machine refrigerant compressed of condensation and heat is outwards discharged; Expansion valve is used to reduce the pressure through the refrigeration agent of condenser condenses; And vaporizer, be used to evaporate the refrigeration agent by expansion valve and absorb outside heat.In refrigeration system, when compressor in when energising and when work, the high-temperature high-pressure refrigerant that compressor is discharged is inhaled into compressor then successively by condenser, expansion valve and vaporizer.Said process repeats.
In said process, condenser produces heat, and vaporizer produces cool air by absorbing outside heat.The heat that cool air that vaporizer produces and condenser produce is fed the interior space selectively, the interior space being heated or freeze, thereby makes interior space maintenance comfort conditions.The compressor that constitutes refrigeration system is diversified.Especially, the compressor that is applied to air conditioner comprises rotary compressor, scroll compressor etc.
Along with the continuous anxiety of earth resource and the deterioration of environment, the energy-conservation constantly target of pursuit of air conditioner that becomes.In order to reduce the energy consumption of air conditioner, be that temperature regime is regulated air conditioner according to the load of the interior space of the device that installs an air-conditioner.In other words, when room temperature sharply raise, air conditioner was in big cold pattern, regulated so that produce a large amount of cool airs.Otherwise when room temperature changed among a small circle, air conditioner was in energy saver mode, kept the room temperature preset so that produce a small amount of cool air.
In order to realize this pattern, usually to controlling, so that change the refrigerating capacity of refrigeration system by the circulating load of the compressor compresses and the refrigeration agent of discharging.Wherein a kind of method as the volume of the cooling medium that is used for controlling compressor discharge is converter plant to be applied to compressor, thereby to change the rpm of the drive motor of compressor.According to the load of the interior space of the device that installs an air-conditioner, the rpm of the drive motor of control compressor, thereby the amount of the refrigeration agent that the control compressor is discharged.The cool air amount that heat that condenser produces and vaporizer produce is controlled by the amount of change from the refrigeration agent of compressor discharge.But, improved manufacturing cost of air conditioner because of converter plant costs an arm and a leg, thereby reduced the price competitiveness of air conditioner.
In recent years, by the control slide plate, it contact with rolling piston or breaks away from and thereby make the transfiguration control technique quilt of pressing chamber work or unloading study application widely.Its typical structure is shown in accompanying drawing 1-accompanying drawing 2, and this existing variable-displacement two-cylinder type rotary compressor comprises: form the housing 1 of outward appearance, form pressing chamber respectively and comprise separately vane slot and first cylinder 8 and second cylinder 2 in slide plate chamber.Wherein, first vane slot is communicated with first pressing chamber and the first slide plate chamber, second vane slot is communicated with second pressing chamber and the second slide plate chamber 3, first slide plate of first pressing chamber is cut apart in motion simultaneously in first vane slot, second slide plate 4 of second pressing chamber is cut apart in motion simultaneously in second vane slot, be communicated with the second slide plate chamber and the interconnecting part of high pressure or low pressure is provided to the second slide plate chamber, this interconnecting part communicates with pressure COMM communication 10, be used for first pressing chamber of airtight first cylinder and the main bearing and the central diaphragm 9 in the first slide plate chamber, be used for second pressing chamber of airtight second cylinder and the supplementary bearing 7 and the central diaphragm 9 in the second slide plate chamber, provide pressurized gas or low-pressure gas by pressure COMM communication 10 to the second slide plate chamber, may command second slide plate 4 contacts with second piston 6 or separates, and then forms the compression chamber pressurized gas or make cylinder idle running in second cylinder 2.Owing on second cylinder interconnecting part that joins with pressure COMM communication 10 will be set, so supplementary bearing 7 is big than the profile of main bearing, promptly this supplementary bearing 7 is bigger with the architectural difference of existing common supplementary bearing, the applying finish surface area of this supplementary bearing 7 and second cylinder 2 increases, can not adopt the production line of existing common supplementary bearing directly to process, need to drop into and to process after more cost is transformed the production line of existing common supplementary bearing, existing production line is an automatic line, the automaticity height, the reforming cost height of existing production line.Simultaneously,, cause the difficulty of processing of this supplementary bearing 7 and processing cost all to increase to some extent, be unfavorable for product promotion because the finish surface area that this supplementary bearing 7 and second cylinder 2 are fitted increases.
