Modding a Haier HWR05XC5 window air conditioner

[RJARRRPCGP]

Does anybody else here have a Haier HWR05XC5 window air conditioner?

If anybody here does, I wonder if it would still continue to run if I just disconnect the temperature sensor?

I'm not familiar with the exact air conditioner, but in general you can do two things. Move the temp probe somewhere warmer (take it off the evap) or just figure out the wiring and bypass it. In general the wiring is VERY simple, like an adjustable thermostat with the temp probe connected to it, along with two wires. Just connect those two wires directly and you have seccessfully bypassed the thermostat.

I've never found moving the temp probe to be terribly effective. Just short the two wires connected to the thermostat. They're usually pretty obvious.

Stick the temp probe to the side of the compressor, that should certianly keep it warm enough to keep things running.

That said, I have never bothered with that sort of thing and just rewire the compressor with my own selection of control electronics. Moveing the temp probe is more of a solution for those who are affraid of wiring.

You'd think so, but somehow it never seems to want to anyways. It lets the temps get low, but for some reason the compressor doesn't run continuously.

When I move the temperature probe to another area, the compressor seems to keep on going, in fact, I had it on long enough for frost to accumulate on the evaporator!! :temper:

How can I stop the dreaded frost from occuring?

The frost occurs because you have a very cold surface in the open air. When the temperature of something drops below the dew point, condensation occurs. When it drops far below the dew point (usually 0°C and lower), the condensation freezes. If you want cold temps, you'll have to insulate the area around evap in some way. Usually people use neoprene, dielectric grease, and silicone for this.

Are you making a chiller or are you doing a direct die system?

Frost is ussualy a good sign. Well for computer cooling, on ac its called "coil icing" and is very bad as air wont flow though a block of ice lol. Are you trying to fix your ac or build a chiller or a DD for your computer?

mine was the hair 5000 btu unit

here is the specs on the compressors

Trying to fix the AC for air chilling.

[Pf.Farnsworth]

Air chilling for pc cooling or room cooling? If pc cooling I would recomend you put the evap in a rez and make a noob chiller, will work much much better. But if you dont have the time thats understandable.

Indeed you dont want ice on your coil if you want to cool air.

temp probe can (well not the probe itself but the information it provides) turn the compressor on/off, could vary the phase, many ways to controll an ac unit.

[Time4aMassiveOC]

basicly just make sure all the air going into the computer is from the airconditioner, as long as all the components in the computer are hotter or the same temp as the air inside and coming in the computer there will be no problems with condensation.

however like Pf said bending the evap so it can fit into a a water resevior would give you the best performance

however in retrospect buying a 100$ a/c unit and chilling the air to your pc is probly the cheapest and easiest way to get subambient temps

[greenmaji]

yea, but sub ambiant case air temperatures are far from the same as die load temps.

[Pf.Farnsworth]

better off using a pelt if you dont want to make a chiller.....
