Embodiment
The constant volume rotary compressor is made up of electric machine assembly 9, cylinder block 5, metal (upper end cap 1 and 7, intermediate clapboard, roll sleeve 3, blade, bent axle 14, exhaust valve plate.This device is that bearing face that will outlet valve be set has not designed a little movable sealing dististyle 2, under the high pressure scavenging action of first passage 6, little movable sealing dististyle and cylinder end face relief opening are combined closely, cylinder is in normal compression-loaded working state, solenoid valve 4 on first passage is received the unloading cut-offing instruction, solenoid valve turn-offs pressurized gas, little movable sealing dististyle action, connect second channel 16 simultaneously, connect with liquid-storage container 13 air cavitys of 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 in the cylinder, pressure outside is identical, and cylinder is in does not have the compression idling conditions; Solenoid valve on first passage receive again load electric instruction, solenoid valve is connected pressurized gas, little movable sealing dististyle action, block second channel simultaneously, the air-breathing low voltage terminal of cylinder is turn-offed, the pressurized gas of the interior compressed generation of cylinder this moment are flow in the high-pressure system by outlet valve and little movable sealing dististyle simultaneously fast, and cylinder is in the compression work state, to begin back and forth.Because the exhaust passage sectional area amplifies at double, therefore reduced compression power consumption, reduced delivery temperature, reduced exhaust noise.Among the figure 8 is shells, the 10th, and outlet pipe, the 11st, tenminal block, the 12nd, loam cake, the 15th, suction tude, the 17th, base.
Another strength member of this device feature is highly sensitive power on/off magnet valve 4, 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 digital variable-capacitance volume rotary compressor, it will replace the use status of frequency-changeable compressor in air-conditioner. It is compared with present widely used constant speed rotary compressor, and following characteristics is arranged:
1, with high content of technology, have good stability and energy saving. 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, and exhaust throttle loss is little, so compare it shake with the constant volume rotary compressor Move and to maintain a lower level. Therefore, the digital variable-capacitance volume rotary compressor has well stable Property and energy saving, noise is 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. It has the electronic circuit of more complicated, in case send out It is very inconvenient to give birth to the fault detect maintenance, is that the air-conditioning maintenance personnel have a headache the most, generally is with whole frequency converter Change. This all is a very big loss to air-conditioner producer and consumer. And digital rotary compressor is logical Varying capacity technology itself that cross has just solved power saving, no longer needs complicated frequency-variable electronic device control, from And reduced 10% circuit and the power consumption loss of electronic devices and components. Digital rotary compressor is handle Complicated power-saving technology is oversimplified, and lays a good foundation for following air-conditioning products upgrading, has saved simultaneously thousand The production cost of surplus yuan of frequency converter can say that also it is than frequency-changeable compressor energy-conservation 10%--20% also.
3, the digital variable-capacitance volume rotary compressor can be good at running under condition of ultralow temperature, and has higher Energy Efficiency Ratio. Digital rotary compressor only has 10% from " load condition " to the conversion loss of " unloaded state ", Be lower than the comprehensive energy loss of frequency-changeable compressor, and the digital variable volume rotation technique can allow compressor 10 Under % to 100% range of capacity, realize the step-less adjustment operation in the gamut, had outstanding season 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.
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.
Compare with digital single cylinder varying capacity rotary compressor, cylinder, roll sleeve and the suction tude of digital twin-tub varying capacity rotary compressor is two, and all the other are all identical.
