Currently the centrifugal chiller is using a water cooled condenser. I am investigating the advantage of using an evap. condenser (cooling tower) to increase efficiency but was concerned about possible problems with lower head pressure.
Thanks for your help!
How would one determine the heating load for a warehouse where all that needs to be heated is the area near the ceiling to 45-50F. All they want to do is keep the pipes from freezeing. How should I determine the heating load for such a case?
Any help would be appreciated.
Thanks!
Thanks again for your help. I will explain my situation..
We have a cylinder of recovered R22 and at 60F we have a pressure of 211 psi. We were using the R22 as part of the high side of cascade refrigeration system with R23 on the low side. We figured there must be a leak in the cascade...
Okay so I tried to validate this sum of partial pressures idea with a blend of R503 [R23/R13(40.1/59.9)] at a temperature of 60F and assumed 100 grams of R503. My numbers just didn't work out. Am I missing something? After taking a look at the ideal GAS law, does it not work for a saturated...
Thank you for your input. I actually have an accidental blend of R23 and R22. Since there is no specific 400 series or 500 series with this makeup, I was wondering the total pressure of the blend at ambient temp. So, Roger, I should assumbe the pressure gauge on this bottle would read the...
How do you figure the total pressure of a cylinder with a mixture of two refrigerants? Will the total pressure be the pressure of the higher pressure refrigerant?
(I am not a military engineer....i am a mechanical engineer...i don't know how that got there.)
I am trying to estimate the total charge in my system and was wondering if anyone knew how much liquid refrigerant would be present in an evaporator coil during normal operation. I was told to assume 25% liquid and 75% vapor in the coil. Is this correct?
