How to use refrigerant to empty the air conditioner after installation

Air, moisture and impurities contained in the air will cause pressure increase, current increase, noise increase, and power consumption increase in the air conditioner system, which will reduce the cooling (heat) capacity, and may also cause ice blockage and dirty blockage.

The influence of machining on fatigue life

The residual compressive stress introduced by shot blasting/shot peening is a percentage of the final tensile stress strength, and this ratio increases as the strength/hardness of the part material itself increases. High-strength/hardness metals are more brittle and more sensitive to surface defects. Shot blasting/shot peening will allow these high-strength metals to be used in fatigue-prone working conditions. Aircraft landing gear is usually designed with a fatigue strength of 300 ksi (2068 MPa), combined with shot blasting/shot peening.
