If the air conditioner within the automotive doesn’t work nicely, then as an alternative of freon there’s water. Water is very harmful. If through the winter the automotive was pushed with out an air conditioner, a big quantity of water might kind in its system. Typically as much as half a glass of liquid accumulates within the hoses. As well as, corrosion is fashioned from water.
In winter, sometimes it’s endorsed to activate the air conditioner within the automotive. However it may be tough to do as a result of, at sub-zero temperatures, the electronics won’t permit it to activate.
The presence of air within the automotive air conditioner is undesirable. It’s harmful that the air is 70 % nitrogen, which has totally different bodily properties, not like freon. Due to this, the load on the compressor will increase considerably. It is strongly recommended to activate the air conditioner sometimes (a minimum of as soon as a month) in winter. In order that water and air don’t accumulate – and the system stays operational, even when it’s not getting used.
Because of the buildup of water within the air flow system, disagreeable odors seem. After all, it causes inconvenience. Having correct AC in your automotive is necessary through the summer season warmth. You may freely seat in your machine, play stay on line casino on-line video games, and relaxation. Within the following article, we’ll evaluation the problem of AC meticulously and how one can repair that.
Is AC Recharged?
In trendy vehicles, as an alternative of the beforehand used freon (R-12), which is harmful for the ozone layer, the much less environment friendly, however safer R-134a freon is used. When recharging, you have to roughly 0.5 kg of refrigerant (for small and medium-class vehicles).
When to Recharge Freon?
This occurs as fluid leaks from the system. As a result of the air con tools within the automotive consists of assorted tubes, then through the operation of the automotive, slight leakage is allowed as a consequence of vibrations. Roughly 10-15 % of the fluid is misplaced per 12 months. Because of this freon is recharged with a totally purposeful system as soon as each 3-5 years.
Causes for Recharging Freon
The air conditioner within the automotive works, nevertheless it doesn’t cool as earlier than;No freon leaks;There aren’t any traces of conditioned oil in any respect joints within the system;The automotive is greater than 5 years outdated or refilled with freon greater than 3 years in the past.
If the air conditioner within the automotive has stopped cooling sharply and the freon has fully leaked out (the system won’t activate – you received’t hear the fan noise), then be sure you undergo the diagnostics. That is performed within the service. Maybe the freon leaked as a consequence of a spot or a rupture within the hose. If the trigger isn’t eradicated, then it should all stream out of the system in 2-3 hours.
Is There a Freon?
You may all the time test the presence of freon with your personal arms. It’s vital to seek out and unscrew the protecting cap from the filling valve on a thick tube (return). After which press the tip of the nipple. Solely right here it is advisable be extra cautious. If there is no such thing as a response or there’s a slight hiss, then there is no such thing as a refrigerant within the system.
Recharging Course of
Listed below are the steps of the freon recharging course of:
Removing of the outdated fluid from the system. Earlier than recharging the air conditioner within the automotive, it is advisable take away the outdated freon (if any). That is performed to seek out out precisely how a lot refrigerant to recharge and to take away oil from it;Leak take a look at – earlier than filling with new freon, it is advisable make it possible for there aren’t any leaks;Oil refill. There’s a small quantity of oil within the system (about 15 grams) to lubricate the friction elements contained in the compressor.Pumping new fluid. After it is advisable activate the air conditioner within the automotive at full energy and test the standard of cooling.
If the air conditioner isn’t totally charged, then there shall be an absence of oil within the compressor. As well as, a poorly charged system doesn’t produce sufficient chilly. Whether it is charged an excessive amount of, elevated stress is fashioned, which additionally results in poor efficiency and system failure.
Recharging By Your self
To fill the air conditioner with freon in a automotive with your personal arms, you have to a can of R-134a freon and a particular package. It features a manometer and connecting hoses. Now let’s take a look at how the method takes place:
We join the canister with the system alongside the thread with the valve wrapped;We connect the filling becoming to the return line (thick tube);We decide the stress within the system on the manometer;If the stress is ample (the stress gauge needle is nearer to the center of the inexperienced zone or reveals greater than 2.5 bar), then it’s not an absence of refrigerant;If the stress is inadequate, then we begin recharging by opening the valve a bit;Be calm and don’t rush. Convey the stress as much as 3 bar. Attempt beginning the automotive’s air conditioner and make it possible for the air from the deflectors comes out at a temperature of about 5-9 ° C. If the temperature is decrease (1-3 ° C) – take out extra freon.
The method isn’t the simplest, the effectivity is common. That is as a result of absence of a vacuum stage and the whole removing of the outdated refrigerant, air, and moisture.
Typically issues seem after a full recharge of the air conditioner within the automotive. Extra usually it happens when driving for a very long time with an empty air conditioner. Water accumulates in it, which causes rust. This may be corrected by topping up the oil and operating the compressor at excessive speeds. However this technique doesn’t work in all circumstances. Therefore, it is advisable completely handle your AC, so as to not disrupt the concord of your automotive.
