Compressor parts, such as compressor body, exhaust tube, noise
eliminator in compressor, supporting spring, etc., will cause resonance
sometimes and give out sound.
(5) Collision between body and shell
Compressor body is suspended by three pieces of spring or supported by
spring in the shell. At starting or stopping, forces acted on compressor
changes greatly and sometimes make the body contact its shell and makes
sound. This situation is of shore duration.
(6) The electromagnetic sound a hermetically sealed motor, is relatively
small
12.6.3 How is the sound of water flowing generated?
Answer: When liquid refrigerant is flowing especially through the
evaporator, there will sound like water flowing. This sound is different, for
the evaporator used and assembly technologies during producing are
different. If there is not this sound at freezer operation, and evaporator
cannot make refrigeration, condenser is not hot, this means there is
restriction or there is a refrigerant leak.
