another fucking AC question
well i finally got the ac to work in my car the only problem is the compressor clutch dosent turn on and off by ifself i got it rigged up. my question is how often should i be fliping it on and off ? every few mins or is it ok just to leave it on all the time

Re: another fucking AC question
the compressor clutch must be engaged for the a/c to work to its full potential. if you disengage it while you still have the fan running you are only going to get cool air until the evap coil is robbed of all its temperature and then you are just blowing air.

Re: another fucking AC question
it isnt supposed to cycle on a timed schedule. it works off of temp from the evaporator. if you leave it on too long you will freeze up your evap. if you dont run it enough the air wont be cold enough. as HMT as the switch is you should really get the temp sensor hooked up. also, it cycles more when you are moving and a lot less when you are at stop lights

Crazy low suction pressure builds ice.

Honduhs use thermostatic expansion valves in place of fixed orifices, the pressure switch is used as an emergency shut off and nothing more. If the system works correctly then the compressor is running all the time. |

Re: another fucking AC question
Sorry Joseph, Honda's cycle the clutch.AC Thermostat testing on pg 22-14 of my 1995 Factory manual
circuit open at 37 degress or less, circuit should close at 39 degrees or more |
Re: another fucking AC question
I've replaced over 14 THX valves on Honduhs. In the field the compressor doesn't cycle unless you have a problem with THX blockage - high side pressure goes up and the system shuts off the compressor.
The incoming warm air is going to keep temps above the freeze point. 38-42 degrees at the vent is what the thermometer says, no cycling. |
Re: another fucking AC question
so i should just put it on a switch and periodicly turn it on anf off ?
