Aircon And Heater

[mikej]

Ok this may sound a bit thick but can someone explain to me why the compressor is used in providing warm air, my car is a 2001 with climate control. I thought the compressor was only associated with the cold aircon but obviously i was wrong as it kicks in and out while my heaters are providing hot air, anybody ? and keep it simple please.... :huh:

if its working then dont worry about it :huh:

 

as advised from this forum using the aircon during winter helps keep the system working correctly,seals etc.and helps clear the front screen a bit quicker.

also the aircon(cold air)will not work below a certain temperature.

if its working then dont worry about it :huh:

 

I'm not worrying about it, just wondered why the compressor kicks in when my heater is set to hot or the highest temp, it works fine supplying the cold air as it should on those warmer days but don't really know why it would be used during the cold one's for example returning homelate one night this week outside temp is approx 3 degrees so i sets my heater to hot to warm us all up, with the window down slightly you can clearly hear the compressor engaging/disingaging etc as well as feel it in the revs. So the aircon works as it should when it's warm outside and supplies ice cold air but why would the compressor be kicking in when i am calling for warm or hot air, anyone know the answer or does anyone elses galaxy does this, is it normal etc???

Air conditioning is more than just heating or cooling. One of the benefits of cooling the air and then heating it up again (which is what happens with the climate control), is that humidity is removed, and this prevents the windows steaming up, and helps clear them if they are steamed up!

 

Also, not running the air con over the winter is quite a good way to encourage leaks as the lubricant included with the regrigerant doesn't get circulated!

 

Hope that answers the question.

Haven't you got an economy setting ( ECON ) as opposed to ( AUTO ).

 

The only difference is that the compressor is not engaged.

Er Nope :huh:

 

Big Kev yes mate i do have a econ setting, i shall try it tomorrow thanks.

After replacing two compressors and the condensor i know all about the benefits of a working system but malcolm.dobell are you saying my system firstly cools and then warms up the air with an outside temp of 3 degrees ? I only want to know what is the connection between my compressor kicking in/out when my heater is working on hot, just don't understand the need for a compressor to provide warm air? Sorry to sound stupid and all that ?? :25:

[mk2vr6]

yes the air passes over the condensor then over the heater matrix,the condensor removes moisture fron said air so when your system is running on AUTO and set to demist the ac will kick in to speed up the demisting process, this has been explain elsewhere several times :huh:

[mikej]

Thankyou for your explanation, i now understand the reason for the optional running of the condensor something i wasn't aware of, obviously i missed the other explanations :huh:

thanks again

mike....
