It is n
ecessary to install a dryer to dehumidify the residual moisture mixed in the
refrigerant in the cycling system. The specially defined molecular-sieve dryer is
advised.
(21) Use the refrigerant of specified brand. When the refrigerant not specified used, it will
possib
ly cause trouble of the performance and reliability of the compressor by the
impurities in the refrigerant.
(22) The lead wires should be connected to hermetic terminals without being touched on the
surface of the compressor.
(23) B
e careful of avoiding oxide scale while soldering during assembly of refrigerating
system.
(for example: flow or fulfill dry nitrogen)
(2
4) The quantity and kind of contamination (the process materials) in the cycle
should
be g
rasped and managed. Carry on reliability test that input contamination a lot than
anticipated contamination quantity.
(25) To avoid water and impurity into he refrigeration system and make sure no leakage of
refrig
erant during the operating course. It’s required to direct the erector and
maintenance man of air-conditioner.
(26) The start-up current and t
orsion of compressor
Adjust t
he start-up current of the compressor to get enough torsion by inverter. Confirm
and measure the start-up current if change the parts and design.
