Chapter 9. Characteristics of each part
9-1. Cycle part function and operating principle
9-1-1. Compressor function and operating principle (Back and forth movement type)
Compressor is composed of the piston part compressing the refrigerant gas from low to high pressure, the motor part for the
operation, and lubricant to accelerate the cooling process and to lubricate the movement.
The low pressure refrigerant is distributed overall within the internal space of the compressor and after being compressed,
the high pressure refrigerant is exhausted through the pipe connected to the external heat emitter.
Caution
u The compressor for service is supplied with nitrogen gas charged and the rubber cap sealed.
This is to prevent internal oxidization and the prevent moisture in the atmosphere from penetrating.
When removing the cap for exchanging the compressor, you can hear a "pik" sound with nitrogen gas
emitting, which means it is a normal product.
If the nitrogen gas is emitted already it means that it is a poor product with moisture penetrated already and
this must not be used.
u The center axis of the compressor is easily shifted from external impact. Therefore you must be especially
careful from impact when carrying or storing the product.
