Phase outside (unheated) - Page 2

post #11 of 20
Actually such a large change in temperature change from the tuned condenser temp WILL produce issues. As the temperature decreases, as will the high side pressure. This would normally be seen in lower suction pressure, and thus lower temperature. But at the same time, the driving flow will drop as well due to a decrease in pressure difference. Thus you will begin to lose load.
It is not possible to predict the total change, but I have seen units go from 250W to 80W when the workshop is just straight up TOO cold.
Scott you should know better.

It will not work if it gets too cold. I tried it with a cascade and posted a thread on xs. At one point my 2nd stage rose to the -40c range. I finally put it in a heated room

Derek this is a single stage cased unit and It will work fine if its cold out but it will struggle under heat.

Derek your single stage also worked fine when it was very cold...

Crazy9000 it may be easier if you call me

Actually I never tried it with the ss. I was advised to put a fan/pressure switch on the 1st stage so I guess I wrongly assumed you'd run into the same problems with an ss. sorry Scott

This is exactly what happened when I ran a blast of cold air though the condenser by opening the door in the middle of winter. The high side would drop in pressure and the evap would get colder until a certain point-- it would completely loose it's ability to cool the CPU and the CPU temperature would shoot up.

The condenser fan needs a fan with thermostat so that it will turn off when the condenser gets too cold.

It took me a while to figure out why you found that funny. "The fan needs a fan" LMAO! I had to type that last bit up quickly right before I ran out the door-- no time to proofread.

I intended to say: The condenser fan needs to be wired to a thermostat so that the condenser temperature doesn't drop too low. Also, It helps to have an oversized condenser and blower fan so that the freon can still condense in 100 degree weather.
