Evacuation is often called vacuum or pulling a vacuum and it s one of the most important parts of the hvacr installation and repair process where the refrigerant circuit is involved. Because all systems are designed to operate without moisture or non condensable gas in the system. It is also the reason behind the breakdown of the motor. Isolate vac pump and torr gauge then use ofn to bring pressure back up to 0 bar.

System has passed strength tightness test ofn vented off in a controlled manner. Non condensable gases in the system can cause chemical reactions which produces acids within the refrigeration system. This is the proper procedure on any us navy ship or. When done properly evacuation also yields which of the following benefit.

Hvac refrigeration evacuation technical refrigeration why is it necessary to evacuate a refrigeration system before charging it with refrigerant. It is important to keep the micron gauge mounted above the system piping this will prevent system oil from entering the micron gauge and possibly causing the gauge to malfunction.

Noncondensable gasses and moisture the two most common system contaminants can be removed through evacuation. Let me be clear from the start that my methods of evacuating a refrigeration circuit are based on experience education and an official guide produced by the us military and their specifications and proper procedures for evacuating a refrigeration system. 3 during this process a vacuum pump is used to draw the sealed hvac system into a vacuum. Our goal should be to keep the closed refrigeration circuit clean dry and tight just like i was taught since the very first week of hvac school.
