Re: Hyundai Air Conditioning
Thank you for the site. However, i found an error in the description of
how an Thermal Expansion Valve operates in the site ; the text says : 'In an expansion valve air conditioning system, refrigerant flow to the evaporator varies according to the pressure in the suction line (evaporator outlet). This is detected by a sensing bulb mounted on the line, and relayed to the expansion valve via a capillary tube ' The refrigerant flow to the evaporator is varied NOT according to the pressure in the suction line , but rather is it based on the pipe surface TEMPERATURE as sensed at the outlet of the evaporator (suction line) by the sensing bulb that is strapped in close contact to the suction line. Its purpose is to maintain a certain superheat value (typically 8-12 degrees f.) so all of the liquid refrigerant is evaporated as it makes it journey thru the evaporator as well as picking up additional heat (superheat) to ensure that only vapor refrigerant exits the evaporator... as a compressor is only designed to pump 100% vapor to avoid possible damage. |

Further...under the Recharging Section of the site , there is another
error . The URL for this section in the site is as follows : Address:http://car-air-conditioning.blogspot...ng-method.html In each of the charging methods listed, it says to hook up the hose to the air conditioning systems' access port then to connect the can of Refrigerant and allow the freon to go into the system ; this is incorrect and a bad practice because air which is present the hose will be forced into the air conditioning system if these instructions are followed. Air and moisture are the two things which must not be allowed to enter any A/C system . The text should have explained the absolute necessity of purging the air out of the hose before releasing the freon into the system. This is one example of why disposable cans of freon should NOT be sold to the general public , as seldom does the average Consumer follow proper guidelines for recharging an A/C system, plus there is alot of danger handling freon in these containers. Summarizing, you have to know what you are doing when it comes to charging an A/C system and it must be properly and accurately metered in ; you do NOT just fill 'er up as you would a gas tank. There needs to be greater regulation concerning aftermarket A/C products that are sold to the general public before more people end up suffering bodily injury (eye injuries and burns mainly) to save money, in addition to messing up their A/C system ... only to have to take it to a qualified A/C mechanic anyway. |

Thanks Dave, i will fix that errors in short notice |
Re: Hyundai Air Conditioning
Your welcome, but, please consider that the general public is put at
great risk of injury when they start messing with substances that are of high pressure and can cause near instant severe burns upon skin contact Some things are better left to the Mechanics who are properly trained to handle refrigerant and who dont guess at how much to put into an A/C system. |
