The present invention relates to the lubricant separator of separated oil from gas and be provided with the air-conditioner of lubricant separator, particularly relate to, be provided with according to installation environment optionally supply with the machine oil that uses in the compressor sump lubricant separator and be provided with the air-conditioner of lubricant separator.
Background technology
In general, air-conditioner is to utilize the heat exchange circulation that is made of compressor, condenser, evaporimeter, expander, to the device of the building that above-mentioned air-conditioner is installed or room cool-air feed or heating installation.Above-mentioned air-conditioner can be divided into detachable air conditioner and integral air conditioner substantially.
Above-mentioned detachable air conditioner and integral air conditioner have identical functions, wherein, detachable air conditioner is installed indoor heat exchanger (evaporimeter or condenser) in indoor set, outdoor heat exchanger (condenser or evaporimeter) and compressor are installed in off-premises station, and above-mentioned two devices that are separated from each other are connected by coolant piping; Integral air conditioner is installed on indoor heat exchanger and compressor, outdoor heat exchanger and expansion structure one in the device.
Include in the above-mentioned integral air conditioner: hang on the window air conditioner that window is directly installed; And connect to suck the air channel and discharge the air channel, and be installed on the air channel type air-conditioner etc. in the indoor outside.Include in the above-mentioned detachable air conditioner: vertically installed floor air conditioner; And hang on wall-hanging air conditioner that metope installs etc.
And above-mentioned air-conditioner also can be divided into: the refrigeration-type air-conditioner that only is used for refrigerating operation; And the heating pump type air conditioner that can be used for refrigeration/warm operation.
And also being extensive use of recently has combined air conditioner, and above-mentioned combined air conditioner is made of at least more than one off-premises station and a plurality of indoor set.
In above-mentioned air-conditioner, after refrigerant compresses, in condenser, carry out condensation in compressor, in above-mentioned expansion structure, expand subsequently, after in above-mentioned evaporimeter, evaporating, will be by can storing the reservoir of liquid refrigerants, and then be recycled in the above-mentioned compressor.
In addition, in above-mentioned air-conditioner, above-mentioned compressor obtains lubricated and cooling by machine oil, the machine oil that uses in the above-mentioned compressor will together be discharged with gas coolant in above-mentioned compressor, therefore, also include lubricant separator in the above-mentioned air-conditioner, the said engine oil separator makes the machine oil of discharging in the above-mentioned compressor separate with gas coolant, and then is recovered to above-mentioned compressor.
Fig. 5 is the profilograph of lubricant separator of the prior art.
As shown in Figure 5, include in the lubricant separator 50 of prior art: staving 52, its inside has set space; Inlet pipe arrangement 54 is used for internal feed gas coolant and machine oil to above-mentioned staving 52; Filter element 56, the net of being installed by the inside of above-mentioned staving 52 etc. constitutes, and refrigerant is passed through, and makes machine oil obtain filtering the back to drop to the lower inside of above-mentioned staving 52; Machine oil recovery tube 58 is used for the machine oil that the lower inside to above-mentioned staving 52 drops is recovered to compressor; Discharge pipe arrangement 60, make gas coolant discharge flow to condenser by above-mentioned filter element 56.
Below, will describe the operation of the lubricant separator of the prior art 50 of structure as mentioned above.
When compressor drives, gas coolant of HTHP (solid line) and machine oil will together be discharged from above-mentioned compressor, gas coolant of discharging in the above-mentioned compressor and machine oil will supply to the inside of above-mentioned staving 52 by the inlet pipe arrangement 54 of said engine oil separator 50.
