Description
Technical field
The utility model relates to Compressor Technology fields, and in particular to a kind of compressor and the air conditioner with it.
Background technique
Low pressure compressor in shell, it is different from high voltage type compressor in current common shell, for the latter, steamed in system
Low pressure refrigerant after hair is directly entered in compression cylinder through air entry to be compressed, and compressed high pressure refrigerant is discharged into compressor housing
It is interior, high pressure in shell, then be discharged by the outlet of compressor housing, into system high pressure condensation side；For the former, compression case
It is in vivo air-breathing low pressure, the low pressure refrigerant in system after evaporation is directly entered compressor housing from the air entry of compressor housing
Interior, refrigerant cools down motor by motor cavity, then is entered in compression cylinder by the air entry on the pump housing and compressed, and presses
High pressure refrigerant after contracting is expelled directly out compressor, or is first discharged into a closed discharge chamber, is then exhausted from compression after carrying out oily separation
Machine, into system high pressure condensation side.
Low pressure compressor in this shell, the low pressure refrigerant after evaporation initially enter in compression case body, and in shell
Heat is generated when motor operation, and temperature is much higher than the low pressure refrigerant after evaporation, therefore the heat that motor generates can be low to low temperature
The refrigerant of pressure is heated, and compression chamber is entered after heating and carries out refrigerant compression.During this, motor heats refrigerant, on the one hand
Increase the specific volume into the refrigerant of compression chamber, i.e., mass per volume declines, and then under refrigerant circulation decline, refrigerating capacity
Drop；On the other hand, compression chamber refrigerant suction and discharge point enthalpy also changes, and causes compression power consumption under unit mass to increase, finally
Compressor efficiency is caused to decline, under same operating, pump housing suction temperature is higher, and compressor refrigerating capacity and COP sharply decline, power consumption
It sharply increases.Therefore in this low back-pressure structure, reduce that the motor feels hot to the heat effect of air-breathing, to improving compressor, system
The efficiency of cooling system is very effective.
