Do you know the degree of leak for you to know that the freon can be gone in 1 day?


I'm no expert either. I just happen to have experience working in one of the biggest airconditioning manufacturers in the world with a BS degree in Engineering.

Cheers!
Well sir, not to offend your BS Engineering Degree (for whatever it is) meaning you're not an engineer ? If you are indeed an engineer you will not hesitate to call yourself Engineer or simply you could say I am an Engineer. There no such thing as a Bachelor of Science and not a degree holder? (BS na nga eh tapos Degree pa? me ganun?) And working in one of the biggest air conditioning manufacturer ? Afraid to divulge your company for it may seems that it is not the biggest manufacturer? I bet you are just an employee. hmmm tsk tsk tsk

Though what you've said about the moisture were correct (since you may have read it also from the internet (google maybe)) I agree with you.

The reason why I mentioned that shaft seal leak is the worst simply because, that seal act like a pressure valve. It can only hold certain amount of pressure (300 psi in some compressor model) before it gave in. Once open it will let huge amount of refrigerant out of the cooling system. Pinhole at the shaft seal cannot hold even 100 psi pressure.

May I ask you a question sir, do you know what will happen to the "freon" if it will leak somewhere in the cooling system ? will that part be cold as if the "freon" is leaking thru it? i'll tell you sir, it will not. what you can see is just a stain of leaked freon.

"The compressor is merely a pump. Its a to pump the freon to a compressed state & heat it up." --- pump indeed sir.. the relationship of compressed gas(pressure) to temperature is "directly proportional"... to enlighten you sir.... as the pressure increases , temperature also increases. converting gaseous state refrigerant back into liquid state. and at lower pressure goes lower temperature; liquid state into gaseous state. that's why discharge side/hose of the compressor is hot to touch and sir heat is not rejected through a/c condenser in front of your car and radiator but it merely lowers down the pressure as for the temperature of liquefied refrigerant

"then expanded again for evaporation (at the cooling coils/eveaporator). "--- correction sir it is not "expanded again for evaporation" it is expanded as it passes through TXV or an orifice that regulates the refrigerant flow into the evaporator.

We're both members of this forum/group since I believed, we both want to help others (not to mislead them) and we're both eager to explore and learn new things that we merely knew.

Cheers also to you sir..
