Fig. 2 is the plan view of Fig. 1.
Embodiment
Digital varying capacity rotary compressor is made up of electric machine assembly 9, cylinder block 2, metal (upper end cap 1,7, intermediate clapboard, roll sleeve 3, blade, bent axle 13, exhaust valve plate.This device is with the former position that outlet valve is set of bearing face, removes exhaust valve plate and valve block backboard, baffler lid, and has redesigned a little movable sealing valve block, back pressure spring, spring jam assembly 5 and shared air vent.This shared air vent is communicated with the housing 8 outer two-position three way magnetic valves 4 that are provided with, solenoid valve high pressure air vent 6 communicates with electric machine rotor lower end in the shell through the two sleeve pipes of water-cooled vaporization cooling, pressurized gas after the cooling are through the electric machine rotor upper end, discharged by loam cake outlet pipe 17, solenoid valve low pressure air vent 15 communicates with the air cavity of liquid-storage container 12.Solenoid valve gets, shared air vent is communicated with high pressure air vent 6, little movable sealing valve block plays the effect of outlet valve, cylinder is in normal compression-loaded working state, when solenoid valve is received the unloading cut-offing instruction, solenoid valve moment shutoff pressurized gas, little movable sealing valve block action, simultaneously shared air vent is connected low-pressure channel, liquid-storage container air cavity moment connection with the air-breathing low voltage terminal of cylinder, the interior pressurized gas of cylinder this moment rush down the air-breathing low voltage terminal of cylinder fast, make the inside and outside pressure of cylinder identical, and cylinder is in does not have the compression idling conditions; When solenoid valve receive again load electric instruction, solenoid valve is connected high-pressure channel, little movable sealing valve block action, block low-pressure channel simultaneously, the pressurized gas of the interior compressed generation of cylinder this moment flow in the high-pressure system simultaneously via little movable sealing valve block fast, cylinder is in the compression work state, to begin back and forth.Owing to the two sleeve pipes of high pressure-temperature gas process water-cooled vaporization cooling, reduced delivery temperature, return in the compressor housing, countercylinder assembly, electric machine assembly 9 are lowered the temperature very favourable, and the while has also been reduced exhaust noise.
The 10th, tenminal block, the 11st, loam cake, the 14th, suction tude 16 is bases.
As shown in Figure 2: the two sleeve pipe water intakes 19 of water-cooled vaporization cooling are connected with the air conditioner condensate water pipe, and the two sleeve pipe water outlets 18 of water-cooled vaporization cooling communicate with atmosphere.Its purpose can reduce pump assembly, electric machine assembly operating temperature, reduces the heat exchange area of air-conditioner condenser, reduces the air conditioner cost of production.
Another strength member of this device feature is highly sensitive power on/off magnet valve, and it can realize the action more than 500-2000 time in per minute, and this solenoid valve is a special two position three-way valve, when electric high-pressure gas circuit logical, the low pressure gas circuit is logical during outage.Understand the digital varying capacity of compressor and regulate, first let us is learnt about the notion of " cycle time ".The one-period time comprises " load condition " time and " unloaded state " time.The capacity regulating of the combination decision compressor of these two time phases.For example: in 30 second cycle time, if the load condition time is 15 seconds, the unloaded state time is 15 seconds, and the compressor regulated quantity is (15 seconds * 100%+15 second * 0%)/30 seconds=50%.If in identical internal burden state time cycle time is 20 seconds and the unloaded state time is 10 seconds, then the compressor regulated quantity is about 66.7%.Capacity is load condition and the time averaging summation of unloaded state.By changing load condition time and unloaded state time, compressor just can provide the capacity output (10%-100%) of any size.
Under load condition, the rotary compressor full capacity is output as (1), and under unloaded state, the compressor capacity no-output is (0).Because in the cycle of setting, therefore conversion between 1 and 0 is called digital rotary compressor.
Another strength member of this device feature is digital varying capacity controller, and it is by environment temperature sensor, and temperature becomes send amplifier, and program counter amplifies final controlling element and forms.When environment temperature sensor sampling amplification compares calculating with setting temperature, calculator sent the instruction motor with fully loaded constant volume running when ambient temperature was spent greater than 2, calculator sends and instructs motor to turn round with the varying load varying capacity when the difference of ambient temperature and setting temperature is spent less than 2, just the solenoid valve unit time gets the resulting cold of electric ratio (heat) and just in time balances each other with at that time environment heat dissipating capacity, this moment, ambient temperature was consistent with setting temperature, accomplished accurate operation, energy-saving run.
The invention of digital variable-capacitance volume rotary compressor, it will replace the use of frequency-changeable compressor in air-conditioner The status.

Because the digital variable-capacitance volume rotary is pressed The contracting machine has been taked unique operation principle in design, and the torque fluctuations that gas compression causes during startup is littler, Starting current is also very little, so compare with the constant volume rotary compressor, its vibration can maintain one Low level. Therefore, the digital variable-capacitance volume rotary compressor has good stability and energy saving, noise Relatively low.
2, complex technology is oversimplified, belonged to the higher product of technology content. The energy-conserving product of current trend As technical support, although convertible frequency air-conditioner has good energy-saving effect, convertible frequency air-conditioner is with frequency conversion Realize energy-saving and frequency-variable with the Electronic Control switch technology. The electronic circuit that more complicated is arranged is in case take place The fault detect maintenance is very inconvenient, is that the air-conditioning maintenance personnel have a headache the most, generally is whole frequency converter is changed Fall. This all is a very big economic loss to air-conditioner producer and consumer. And digital rotary compressor Varying capacity technology by itself has just solved power saving, no longer needs complicated frequency-variable electronic device control, Thereby 10% circuit and the power consumption loss of electronic devices and components have been reduced. Digital rotary compressor Be that complicated power-saving technology is oversimplified, lay a good foundation for following air-conditioning products upgrading, save simultaneously The production cost of over thousands of first frequency converter and the production cost of anti-interference device, can say that also it compresses than frequency conversion Machine is also wanted saving energy 10%--20%, and decrease air-conditioner complete machine production cost is conducive to energy-conservation simultaneously The popularization of product.
3, the digital variable-capacitance volume rotary compressor can be good at running under condition of ultralow temperature, and has more High Energy Efficiency Ratio. Digital rotary compressor only has 10 from " load condition " to the conversion loss of " unloaded state " % is lower than the comprehensive energy loss of frequency-changeable compressor, and the digital variable volume rotation technique can allow compressor exist Under 10% to 100% range of capacity, realize the step-less adjustment operation in the gamut, had outstanding season The joint Energy Efficiency Ratio.
4, realized that by the partial structurtes that change the bearing cylinder end cap compressor is in 10% to 100% range of capacity, reach the step-less adjustment operation, this structure great advantage is just can produce the varying capacity rotary compressor on the production line of existing production constant volume rotary compressor, and product has been realized upgrading.Compressor manufacturing enterprise increases investment hardly, just realized the production model change of whole rotary compressor industry, profit margin has very big lifting, air conditioner manufacturer is not needed to join type, change lower margin, save the investment of production line frock jig, go into operation fast transition, reduces the air conditioner cost of production.Can seize commercial opportunity fast.5, its interference that do not generate electromagnetic waves of digital variable capacity rotary compressor does not have impact, noiseless to electrical network, and is noiseless to wireless device, and human body is not had hurt of electromagnetic wave, belongs to nuisanceless, energy-conservation, green, environment-friendly products.Belong to Chinese independent intellectual property right, favourable to exporting.
6, the employing of water-cooled vaporization cooling double-tube structure form can reduce the heat exchange area of condenser, saves copper pipe, aluminium, reduces the air conditioner cost of production.
Solution is such as vibration, noise, improves Energy Efficiency Ratio, the variable-frequency electromagnetic wave interference is hurted sb.'s feelings, and these are the rotary compressor industry technology personnel goals to fight for of seek assiduously.Several key technical problems above digital rotary compressor has well solved.
