Description
Technical field
The present invention relates to a kind of twin-stage positive displacement compressor and with its air-conditioning system.
Background technique
With the increasingly raising of national efficiency class requirement, existing twin-stage positive displacement compressor is solved by Gas-supplying enthalpy-increasing
The problem of low-temperature heating capacity deficiency, so that air-conditioning heating measures satisfaction.But twin-stage positive displacement compressor is due to there is hiigh pressure stage and low
Two cylinders of arbitrarily downgrading are compressed, for operating condition (name refrigeration, name heating, national standard operating condition, the worst cold case of heavier loads
Deng) for, pressure ratio is larger.Effectively pressure ratio can be allocated using Two-stage Compression, so that height is arbitrarily downgraded, cylinder can be rationally
Operation.For the light load conditions (such as IPLV operating condition, intermediate operating condition etc.) of air-conditioning system operation, pass through displacement-variable device
Carry out mesolow switching realize the transfiguration of single cylinder single-stage operating can effectively solve the problems, such as light industry condition operation when efficiency it is low, but in it is low
Crush-cutting is changed to be affected by operating condition, and pin, which may have malfunction, leads to handover failure.Specifically, existing scheme lower cylinder is sliding
Piece slot tail be connected to by partition air slot and lower cylinder air slot with intermediate cavity, by displacement-variable device realize in press and low pressure
Switching.Under twin-stage operation mode, intermediate cavity is middle pressure, and pressure difference suffered by pin is the pressure difference of middle pressure and low pressure.By operating condition
Be affected, it is understood that there may be mesolow pressure difference is less than spring force and the hidden danger that causes twin-stage to be unable to operate normally.
In current compressor, there are many movements that the lockable mechanism of form is used to control slide plate.One is pass through on-off
The movement of Electromagnetic Control pin, this method are related to the installation and reliability of electromagnet, and compressor complete machine structure and control are more multiple
It is miscellaneous；Another kind be by switch pin tail portion pressure of inspiration(Pi), pressure at expulsion, under the resultant force with spring force control pin movement from
And lock slide plate or operate normally slide plate, spring is set to the head of pin, needs to increase position limiting structure, causes structure multiple
Miscellaneous, in addition, this method is only applicable to the compressor set of low back pressure operation, and slide plate tail portion must install spring；In one kind
The slide plate slot tail for being unloading cylinder is sealing structure, passes through the pressure control vane motion for switching slide plate slot tail.Pin needs
Vane motion could be lockked in the case where there is pressure difference.And be mounted on the pin on lower flange installation it is complex, be mounted on down
The method limited in flange silencing cavity with muffler is higher to the hardness requirement of muffler.In addition, the high pressure of the patent is from oil
The high pressure oil that pond introduces, to guarantee the lubrication and sealing of slide plate, but also brings sliding vane groove oil accumulation to make in slide plate operational process simultaneously
The hidden danger that power consumption increases.
