pressure at gas exhausting tube and returning tube will get balance, thus
causes sound of compressor.
(4) At the starting of compressor, if the voltage is low, the hammer
type-starting relay will make loud sound. Even if stabilizer is equipped with,
measurement should be made in time. If it cannot reach the requirement of
stabilizing, there must be quality problem with it, please don
’t use in case
the voltage output is low.
For the previous reasons, freezer makes sound at starting and stopping.
12.6.15 Why sometimes noise at far distance is greater
than at near distance?
Answer: Because the transfer of freezer noise has relations with freezer
position, room space, etc. The sound wave giving out at freezer operation
will reflect when it touches wall or furniture. So it is possible that at a far
distance, it is noisier than near distance. So it is not correct to make
decision of big sound just by it can be heard meters away.
