Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to vortex rotator type twin-stage air condition compressor of the present invention.
See accompanying drawing 1,2, vortex rotator type twin-stage air condition compressor, comprises housing 1, low pressure compression pocket 2, high pressure compressed room 3, liquid-storage container 4, motor 5, oil feed pump 6, middle air jet pipe 7, outlet pipe 8, muffler 9 and Direct box 10.Motor 5 is arranged on the middle part of housing 1; Low pressure compression pocket 2 is single rotor pressing chamber, is arranged on the bottom of motor 5, is connected with liquid-storage container 4; High pressure compressed room 3 is scroll compression room, is arranged on the top of motor 5, is connected with the outlet pipe 8 at housing 1 top; Middle air jet pipe 7 is connected with housing 1, is arranged on the middle part of housing 1; Muffler 9 is connected with liquid-storage container 4, and muffler 9 is arranged on the top of liquid-storage container 4; Liquid-storage container 4 is arranged on the side of compressor, and oil feed pump 6 is arranged on the bottom of housing 1; Direct box 10 is arranged on the top of housing 1.
Vortex rotator type twin-stage air condition compressor can be applicable to constant speed or frequency-changeable compressor, DC frequency-changing or AC frequency conversion compressor.
Working principle of the present invention is as follows: motor 5 operates, and liquid-storage container 4 delivered to by the refrigerant gas cooled via return air pipe 9 of low-temp low-pressure, and suck low pressure compression pocket 2, first compression is the gas of medium temperature and medium pressure, and gas is discharged in housing 1.After the medium pressure gas that middle air jet pipe 7 sucks mixes in housing 1 with the gas that low pressure compression pocket 2 compresses, suck high pressure compressed room 3, secondary compression is the gas of High Temperature High Pressure, discharges from outlet pipe 8.Now oil feed pump 6 operates, and refrigeration oil supplies in whole housing 1 through oil feed pump, plays lubrication effect.
Existing single stage compressor is at operating pressure than time large, and its leakage loss and mechanical loss can increase, and the efficiency of compressor significantly reduces.And adopt vortex rotator type two-stage compression to construct, its leakage loss and mechanical loss reduce to minimum, operating pressure than compressor efficiency time large without reduction, compare existing compressor, efficiency significantly promotes more than 30%, can realize operating range wide, significantly high efficiency.
Existing air injection enthalpy-increasing compressor, directly jet in pressing chamber, refrigerant gas losses by mixture can be produced time jet, affect compressor efficiency.Under ultra-low temperature surroundings, heating capacity has decay in various degree, and when usual-7 DEG C, heating capacity is 80% of standard heating capacity; When-20 DEG C, heating capacity only have standard heating capacity less than 50%.And adopt vortex rotator type two-stage compression+middle jet structure, suck pressing chamber again after refrigerant gas mixing, gas and vapor permeation loss can be reduced, improve compressor efficiency.By the jet increase circulating mass of refrigerant in centre, the liquid refrigerant circulating load entering vaporizer is reduced, and compressor horsepower reduces, and Energy Efficiency Ratio promotes, and under realizing ultra-low temperature surroundings, heating capacity is undamped, and when-7 DEG C, heating capacity reaches standard heating capacity; When-20 DEG C, heating capacity is 70% of standard heating capacity, and Energy Efficiency Ratio significantly promotes.Compare existing compressor, when-20 DEG C, heating capacity promotes 25%, and Energy Efficiency Ratio promotes more than 50%.
Existing compressor adopts crankshaft heater to compressor preheating usually, can start and heat under making low temperature environment.And vortex rotator type compound compressor makes the effective preheating of compressor by loss phase heating.Direct box 10 blocks 1 in 3 wires connecting motor 5 in advance, increases the load of motor 5, makes motor 5 self-heating, and then compressor entirety is reached a high temperature.Use a small amount of electric power to the prior preheating of compressor, just can start rapidly and heat.Without the need to crankshaft heater, stand-by electric is low.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
