See Fig. 2; Compressor body 12 comprises housing 15, upper cylinder 17, dividing plate 18, lower cylinder 14, lower flange 19, lower cover plate 20, compressor exhaust pipe 1 and increases enthalpy pipe 13; Upper cylinder 17, dividing plate 18, lower cylinder 14, lower flange 19 and lower cover plate 20 are from top to bottom successively in the fitting seat housing 15; The first liquor separator outlet pipe 9 is communicated with the first intakeport 14c of lower cylinder 14, and the second liquor separator outlet pipe 8 is communicated with the 3rd intakeport 17a of upper cylinder 17.The volume of upper cylinder 17 is less than the volume of lower cylinder 14, and upper cylinder 17 is 0.3 to 0.95 with the volume ratio of lower cylinder 14.Carry out the compression second time because refrigerant enters into upper cylinder 17 after lower cylinder 14 once compresses, the density of compression back refrigerant becomes big for the first time, so the volume of upper cylinder 17 diminishes, the scope of best volume ratio is 0.6 to 0.8.
See Fig. 3, Fig. 4, lower cylinder 14 is provided with vane slot 14b, and the afterbody of lower cylinder 14 vane slot 14b does not have spring eye, is closed body.On the outer side surface of lower cylinder 14, be provided with the first intakeport 14c, the second intakeport 14d and relief opening 14f; The first intakeport 14c and relief opening 14f communicate with the inner chamber 14a of lower cylinder 14; Relief opening 14f is connected with the other end of by-pass stack 10; The second intakeport 14d is communicated with the afterbody of vane slot 14b through inclined hole 14e, and the second intakeport 14d is communicated with the 3rd mouthful of C of three-way valve 5 through connecting tube 7.Angle theta between the center line of the center line of the first intakeport 14c of lower cylinder 14 and its second intakeport 14d is that 30 degree are to 150 degree.Angle δ between the center line of the center line of the first intakeport 14c of lower cylinder 14 and its relief opening 14f is that 35 degree are to 150 degree.The diameter of inclined hole 14e is 1mm to 6mm, and the angle between inclined hole 14e center line and the vane slot 14b center line is that 35 degree are to 60 degree.
See Fig. 5, on dividing plate 18, be provided with boss 18a, dividing plate 18 closely cooperates through boss 18a and lower cylinder 14, prevents that refrigerant from leaking from inclined hole 14e.
See Fig. 6, on lower flange 19, be provided with boss 19a and expansion silencing cavity 19b, closely cooperate through boss 19a and lower cylinder 14 on the lower flange 19, prevent that refrigerant from leaking from inclined hole 14e.Expansion silencing cavity 19b with increase enthalpy pipe 13 and be communicated with, carrying out compressor when heating, the refrigerant in the condenser enters into flash vessel and flashes to gaseous coolant, enters into lower flange 19 and carries out tonifying Qi and increase enthalpy through increasing enthalpy pipe 13 subsequently, directly improves the heating capacity of compressor.Lower flange 19 closely cooperates with lower cover plate 20 and forms the intermediate pressure cavity of airtight band silencing function, reduction noise that can be by a relatively large margin with improve air compensation.
The working principle that the varying capacity twin-stage of the foregoing description increases the enthalpy compressor is following:
(1) when the operating mode of air-conditioning system is cooling condition: solenoid valve 11 is opened, and first mouthful of A and the 3rd mouthful of C conducting of three-way valve 5 are behind the compressor start; The low pressure refrigerant that sucks from liquor separator suction tude 2 enters into the afterbody of lower cylinder 14 vane slot 14b through connecting tube 4, three-way valve 5 and connecting tube 7, because the pressure of low pressure refrigerant is identical with the pressure of refrigerant in the lower cylinder 14, the interior slide plate two ends of vane slot 14b can not form pressure difference; Slide plate can not slide; Refrigerant in the lower cylinder 14 just enters into the second liquor separator outlet pipe 8 from by-pass stack 10 without overcompression, compresses to upper cylinder 17, because the volume of the volume of lower cylinder 14 and lower cylinder 14 and inequality again; The volume of lower cylinder 14 is much larger than the volume of upper cylinder 17; By this movement process, have only the refrigerant of upper cylinder 17 to circulate, reduced the cold medium flux in the system; Reduction system input power, the Energy Efficiency Ratio of raising system.
(2) when the operating mode of air-conditioning system is heating condition: solenoid valve 11 cuts out; Second mouthful of B and the 3rd mouthful of C conducting of three-way valve 5; Behind the compressor start; The HTHP refrigerant that sucks from compressor exhaust pipe 1 enters into the tail end of the vane slot 14b of lower cylinder 14 through connecting tube 3, three-way valve 5 and connecting tube 7, because the pressure of HTHP refrigerant is greater than the pressure of refrigerant in the lower cylinder 14, the slide plate two ends in the vane slot 14b form pressure difference; Slide plate under the effect of pressure, be pushed to lower cylinder 14 in lower roller contact that (it is through the spring that is contained in the spring eye slide plate to be contacted with lower roller that existing twin-stage increases the enthalpy compressor; Therefore, the varying capacity twin-stage of present embodiment increases the enthalpy compressor can save spring eye and spring in the lower cylinder), thus refrigerant is compressed.Owing to there is not refrigerant from by-pass stack 10, to discharge; All refrigerants in the lower cylinder 14 all compress, the refrigerant in the lower cylinder 14 all enter into lower flange 19 and from the refrigerant of condenser 22 and flash vessel 21 after the expansion silencing cavity 19b of lower flange 19 mixes again through dividing plate 18; Enter into upper cylinder 17 again and carry out the compression second time; This moment, the cold medium flux of compressor was more, and the input power of compressor is higher, can in system, obtain higher heating capacity and heating energy efficiency ratio.
This shows; Adopt the varying capacity twin-stage of the utility model to increase the adjusting that the enthalpy compressor adopts single twin-stage switching way realization capacity; Can be applied in preferably in the low-cost high energy efficiency air-conditioning system; Ultra-low temperature surroundings below can safe and reliable being applied in-20 degree centigrade has higher heating capacity and Energy Efficiency Ratio simultaneously.
More than be merely the specific embodiment of the utility model, do not limit the protection domain of the utility model with this; Do not violate any replacement and the improvement of being done on the basis of the utility model design, all belonging to the protection domain of the utility model.
