Abstract

An energy-saving vortex machine for air conditioners, comprising a casing, a pair of vortex rotors and a vortex stator are packaged at both ends of the casing, the two vortex rotors are fixed on one end of the two crankshafts, the other end of the crankshaft and the middle of the casing The phase configuration of the motor can not only save energy, but also allow the use of gas working fluid that has no damage to the ozone layer when this scroll machine is used in the air-conditioning system to achieve pollution-free refrigeration.

Description

Energy-saving eddying machine for air conditioner

The present invention relates to a kind of scroll machine, relate to a kind of scroll machine that combines by scroll compressor and scroll expander specifically.

In the existing vapor compression air conditioning equipment, what generally adopt both at home and abroad is throttling refrigeration method, compare with the refrigerating method that adopts decompressor, though have identical effect aspect the pressure of refrigeration working medium, the temperature reducing, throttling refrigeration exist energy loss big, be subjected to shortcoming such as working medium kind restriction.

Order of the present utility model is to provide a kind of energy-saving eddying machine for air conditioner, adopt decompressor to replace throttle valve, not only can freeze, and when in air-conditioning system, adopting this scroll machine, allow to use the gas that ozonosphere is not had destruction as working medium, realize pollution-free refrigeration.

Accompanying drawing is a structure principle chart of the present invention.

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are elaborated.

With reference to accompanying drawing, the present invention includes a shell, be packaged with a pair of vortex rotor and vortex stator 1,2, two vortex rotors 1 are connected two bent axles 3,4 respectively by thrust ball bearing 9,10 a end in the two ends of shell respectively; The phase difference of bent axle 3,4 is 180 °, rotor 7 phase configuration in the middle of its other end and shell are interior; There is a lubrication system bottom surface of vortex rotor 1, this lubrication system comprises a partition ring 16 that is slidingly matched with frame 5,6, partition ring 16 is placed in the chute 22 on the frame 5,6, chute 22 is connected with the oil groove 23 of frame 5,6 sides, the spring 24 on configuration one guiding valve 14 and guiding valve 14 tops in the oil groove 23, guiding valve 14 has T type oil groove 25, and T type chute 25 and oil storage tank 28 are connected; There is a lubrication system side of vortex rotor 1, said lubrication system comprises out the chute 26 on frame 5,6, one end and the oil groove 23 of oil groove 27 communicate, and the oil supply hole road 15 on the other end and the vortex rotor 1 communicates, in the chute configuration one guiding valve 13 and on spring 27.

The working principle of this scroll machine is: gas enters the middle part of scroll machine by suction port 17, behind the cooling motor, enters the compressor air suction chamber by the passage of opening on frame 5,6 and vortex stator 2 18; Gas after being compressed is flowed out by vortex stator mider hole 19.Gas enters decompressor by hole 20 after the cooler cooling, the cooling back of expanding is flowed out by hole 21, enters heat exchanger and absorbs heat, enters the scroll machine middle part by suction port 17 again after the re-heat, finishes a circulation.

When partition ring 16 was subjected to the upper and lower motion of effect of vortex rotor 1, lubricant oil was inhaled into fuel supply chamber and is pressed into the epitrochanterian oil supply hole 15 of vortex, and lubricant oil flows to each lubricated surface by oil supply hole 15 through lubricating oil path, realized lubricated; When 1 motion of vortex rotor, oil is inhaled into fuel supply chamber through guiding valve 14 simultaneously, and when guiding valve 14 moved downward, oil was pressed into oil supply hole 15.

Scroll machine according to the present invention's development can obtain following effect:

1, scroll expander by eccentric shaft, can pass to scroll compressor as the parts of exportable mechanical work with expansion work, reduces power input to a machine effectively.

2,, all can produce cold effect through the decompressor back of expanding, thereby this machine permission use as working medium, realizes the purpose of pollution-free refrigeration to the gas of my destruction of ozonosphere regardless of the kind of expanding gas.

3, when this machine is done in the chiller plant to be, because under identical condition, working medium less than the working medium irreversible loss of throttle valve of flowing through, so can improve the efficient of refrigeration cycle, plays the purpose of indirect energy saving through the irreversible loss of decompressor.
