R32 Refrigerant charging-step by step procedure Part 2

All the refrigeration systems are designed to run without moisture and non-condensable gases else it may not work as designed and is likely to fail prematurely.
The presence of moisture in the air conditioning system may lead to the formation of acidic sludge in the oil and may cause restrictions on various places like expansion valve and evaporator coils thereby reducing the overall cooling effect.
In case of a hermetic compressor, it may cause deterioration of the insulation winding which may lead to a short circuit and compressor motor burn out.
Non-condensable gases are just air which can enter during refrigerant charging, repair or maintenance. These gases take up space in the condenser and limit the amount of liquid refrigerant leading to reduced cooling efficiency.
Evacuation is carried out by using a vacuum pump and a recovery bottle, ones the system evacuates we need to wait for about 20-25 min to check the pressure gauge is holding the negative pressure (vacuum) as shown in the image.
This process may ensure that there are no leakages in the system as chances are air or moisture could enter via pipe cracks or leaky gasket or joints while performing evacuation procedures.
In the above image, we can see there are two devices fitted one is an analog pressure gauge showing the final negative reading and another one is a digital vacuum gauge showing 500 microns as final reading, connected to the same line to ensure the system is 100% evacuated

Thenks sir inverter AC ke aise hi video banao

[@Yunusiv]

Perfect work..hioki ka apms meter 1nmbr hai bhai

[@SMARTAIRCOOLSYSTEM]

Han bhai

[@Yunusiv]

@@SMARTAIRCOOLSYSTEM same meter Mai bhi use krta hoon

[@arifmalek8364]

Kya name Hai whaight machine ka Kaha milega

[@Ab_035]

Mera ek question tha, ye jo compressor blast hota hain ye Window AC bhi hota hain aur sirf Split AC?

[@SMARTAIRCOOLSYSTEM]

kya r 32 ko vapor main be charge kr skty hin ??

[@SMARTAIRCOOLSYSTEM]

Han kr skte hai

[@Shivanahudwivedi53341]

Sir kya jitni gas charge karni hai ek baar me dal skte hai

[@u.s1]

Humko bhi apne sath rakh lo bhai

[@goutamsutradhar9642]

Sir, R32 gas duplicate hota hai

[@AzharAli-ds2ht]

Nice
pr har insan tarazu le ke nhi chal sakta

[@SMARTAIRCOOLSYSTEM]

Right
