Re: Lets talk AC again

Oh well.

High voltage electricity powers the electric motor, generator, air conditioning compressor and inverter/converter. All other automotive electrical devices such as the headlights, radio, and gauges are powered from a separate 12 Volt auxiliary battery. Numerous safeguards have been designed into the Prius to help ensure the high voltage, approximately 201.6 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle (HV) battery pack is kept safe and secure in an accident.

I'd prefer to have a cooling system with its own engine. They used to have them but the name eludes me.

Re: Lets talk AC again

Ease and costs in repair and replacement need to be kept in mind.I looked into ThermoKing since we had a big repair/installation facility in Chattanooga (only 60 miles away from us a the time). This was for our Eagle 05. ThermoKings are expensive to buy and repair. But it was for a "coach" and like everyone else, we felt the expensive shell validated the more expensive "thing". Not just the air conditioner but everything we were putting in. The reason I pulled back from the ThermoKing (other than the overall costs) was how sparsely the repair shops were spread out. I had visions of the unit pooping out on us and having to drive 150 miles (a real distance) to get to the nearest repair shop during a South GA heatwave and have to wait a week in Atlanta while the unit was repaired. At the time David was the one who was working. That was not a feasible option.

We have set the BlueBird up to where we can repair almost everything on/in it by stopping at Home Depot, Lowes, ACE, TruValue, Wal-Mart and either make repairs or replace. Because we have found one or more of these stores in almost every decent sized own on the primary highways that we like to travel on.

Re: Lets talk AC again

Here is a company that sells replacement refrigerant for automotive AC.....it's 85% propane and 15% butane.

http://www.coolearthinc.com/faq.htm

This is the website that convinced me to use propane as a refrigerant.

my theory on why propane isn't used more often as a refrigerant......because there is no money in it. I think that corporations like DOW work very hard to make sure the chemical they own the patent on is the one that gets used.

according to wiki, freon (r12) when exposed to heat creates phosgene, also known as mustard gas.

Quote:
Phosgene may also be produced during testing for leaks of older-style refrigerant gases. Chloromethanes (R12, R22 and others) were formerly leak-tested in situ by employing a small gas torch (propane, butane or propylene gas) with a sniffer tube and a copper reaction plate in the flame nozzle of the torch. If any refrigerant gas was leaking from a pipe or joint, the gas would be sucked into the flame via the sniffer tube and would cause a colour change of the gas flame to a bright greenish blue. In the process, phosgene gas would be created due to the thermal reaction. No valid statistics are available, but anecdotal reports suggest that numerous refrigeration technicians suffered the effects of phosgene poisoning due to their ignorance of the toxicity of phosgene, produced during such leak testing. Electronic sensing of refrigerant gases phased out the use of flame testing for leaks in the 1980s. Similarly, phosgene poisoning is a consideration for people fighting fires that are occurring in the vicinity of freon refrigeration equipment, smoking in the vicinity of a freon leak, or fighting fires using halon or halotron.

Re: Lets talk AC again

this last trip , we got into some very hot days, what we did was use a curtain behind the portable a\c , works ok keeping the cab of the bus cooler, you have to run the jenny, but that's ok the cold air is needed more then just burning a little gas in the jenny

Re: Lets talk AC again

I am interested in this thread. At first I was thinking.... UMMMM NO PROPANE IS FLAMMABLE......but the more I thought about it, some of us will have propane lines and bottles on board so the risk will be there regardless. So why not use it? I am currently going through HVAC school for residential and commercial applications. So I am seeing, reading, and experiencing those things in labs so it is exciting to maybe put them in place in my bus.


Keep the ideas going. Very interesting
