Specific embodiment
Applicant it has been investigated that, in the course of work of compressor, suction atmidometer and clearance volume are to affect pressure
Two key factors of contracting engine efficiency, the wherein size of suction hole pore size influences inspiratory resistance, steam vent aperture is then to affect row
The important feature parameter of atmidometer and clearance volume.Suction air pressure in the course of work of convertible frequency air-conditioner, under middle operating mode
Difference is less than the suction draught head under declared working condition, and under middle operating mode compressor rotating speed it is relatively low, therefore suction gas opening
Flow velocity is compared declared working condition and is had and significantly declines so that suction atmidometer also declines to a great extent.Now, suction gas opening sets
The diameter for being impact of the clearance volume for compressor efficiency, reducing steam vent of meter overriding concern, can effectively reduce clearance appearance
The impact that product is brought to compressor efficiency；But meanwhile, if aerofluxuss bore dia is too small, the flow velocity that it brings rises can then cause aerofluxuss
Resistance rising is excessive, and so as to weaken clearance volume the positive influences brought to compressor efficiency are reduced.At present, the air-breathing of compressor
Ratio general satisfaction 1.2≤A1/A2≤2.9 of hole cross-sectional area A 1 and steam vent cross-sectional area A 2, but the ratio in the range of being somebody's turn to do
The requirement of energy conservation of compressor cannot be met.Therefore, it is necessary to carry out appropriate design to the size of suction pore, it is ensured that clearance volume shadow
While ringing reduction, the impact that exhaust resistance is brought also reduces.
Based on this, this utility model provides a kind of cylinder of rotary compressor, rotary compressor and convertible frequency air-conditioner, to solve
