Abstract :
In this era, the world temperature is rising.
Manufacturers in the air conditioning industry are
developing environmentally friendly compressors and
refrigerants. However, the current refrigerant, R32, has a
very high pressure, which negatively affects the copper
pipes of the air conditioner, making them prone to leaks.
To save costs, a brazing method is often used to connect the
pipes, but this method often causes repeated leaks in the
welded area. This study was conducted experimentally by
testing the welded pipes, applying pressure, and examining
the microhardness. The purpose of this study is to analyze
the microhardness of the welding results of copper
material on 0.41mm, 0.58mm, 0.61mm AC pipes. The
results of reading this journal provide insight into the
welding results of copper pipes in air conditioning systems
by pressure test and hardness test.
