The compressor

Today is my first day to write blog on the net after I started to work .I hope that I can write somethings about my  life and work everyday. now,I want to introduce something about my work.The compressor is the heart of refrigeration system,and it is a fluid machiner that promoting to high pressure gas to low pressure gas. It sucts low temperature low pressure refrigerat gas from air suction pipe , and a piston, which run by a motor, compresses it.the exhaust pipes of high temperature and high pressure refrigerant gas, to provide power for refrigeration cycle, so as to realize the compression and the condensation - inflation - evaporation refrigeration cycle (heat)
