18 Purge parts with dry nitrogen or dry air to remove remains in parts (dust, detergent, etc.)
before
assembly of system. Time fur purging: over one second for pipe; over three seconds for
heat exchanger. Purging pressure: 0.9±0.1MpaG. Dew point of dry air: Below –20℃.
The motor winding temperature should be less than 149℃and hermetic terminal body
temperature should be less than 177℃in process of manufacturing.
19 Apply for vehicle
The c
ompressor should not be used on moving equipment such as automobiles,trains,ships, etc.
20
Installation
The r
otational axis of compressor should be kept vertical during operation. But in actual
application the axis incline must be within 5°at all directions during operation.
21
Pipe vibration
The displacement of
the pipes, which connect from the compressor to other parts of the
refrigerate-or systems, should be less than 0.8mm(1/32”)when the compressor is operating at
allowable rotational speed range and voltage range of rated ±10%.
Displacement in excess of 0.8mm(1/32”) will require changing tube length and/or routing.
22 Connecting tube design
In designing and routing tubing that connect from the comprssor to the other parts of the air
conditioner, following should be considered.
