5. The compressor of LG refrigerator is generally proced by LG. In the 2005 new proct and Guibing refrigerator, the compressor adopts TCM compressor, which has two intelligent operation modes of forward rotation and reverse rotation. It has the advantages of small power consumption, strong refrigeration effect and low-pressure start-up. General compressor: a kind of driven fluid machinery that promotes low pressure gas to high pressure gas, which is the heart of refrigeration system. It sucks the refrigerant gas with low temperature and low pressure from the suction pipe, drives the piston to compress it through the operation of the motor, and then discharges the refrigerant gas with high temperature and high pressure to the exhaust pipe to provide power for the refrigeration cycle, so as to realize the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
6. Turn on and off frequently. It takes a long time to preheat the copier before it works every time. Only when it is preheated, can the copier start to work. Under normal circumstances, we will use the copier to a large number of documents, but it does not rule out the frequent use of the machine in the case of multiple applications. Although this kind of frequent switch on and off is also in line with the operation steps, frequent start-up of the copier will damage the internal optical components of the copier to a certain extent, and long-term persistence will shorten the service life of the copier, in other words, make the copier overworked.
