DISCHARGE TEMP ON AIR COOLED RECIPROCATING CHILLER
DISCHARGE TEMP ON AIR COOLED RECIPROCATING CHILLER
(OP)
Hi guys---
What would be considered an excessive discharge temperature on an air cooled reciprocating chiller?
Thanks for your time.

I'm taking a test with 120 questions and only got about 25 of them right.
I've only just completed a 6 month training in the basics of
HVAC/R and we did not go over anything in depth relating to the "Big Stuff" such as centrifugal chillers, cooling towers, boilers, and basically any thing over 5 tons.
The job I'm currently interviewing with looks like they are going to hire me and give me the training to work on the larger equipment.
The lead tech I'm going to be training under told me to go out and find as many answers as I could by any means.
I've been surfing the net, going to the library and making phone calls. It seems to me that a lot of this information
I'm seeking is stored away in company manuals that cost major $$$. So I will keep searching.
@ MintJulep--- I think you are right-- 958 C would be toasty.

R-22 applications require an oil cooler when (absolute)
pressure ratio is greater than 5.0; oil cooler and
water-cooled heads required when discharge temperature
is greater than 250 F.
R-134a applications require an oil cooler and watercooled
heads when the discharge temperature is
greater than 275 F.
R-507/404A applications require an oil cooler when
the SST is less than –20 F and require an oil cooler
and water-cooled heads when the discharge temperature
is greater than 275 F.
Good luck with the job. By the way you can get a lot of the manuals on the web.
It will vary somewhat on the compressor.
RE: DISCHARGE TEMP ON AIR COOLED RECIPROCATING CHILLER
With no details about the compressor or application, there really is no way to answer the question.

Generally if you take the discharge temperature and add 75 degrees that is the aprox. temperature of the vapor/oil at the discharge valves.
I'm not a real engineer, but I play one on T.V.

I think a copy of this thread stapled to the question
should work as a acceptable answer.
One thing I've noticed is that a question without spec's is very hard to answer indeed.
@MintJulep---LOL, I kinda thought you was test'n me

Your end compression temperature is following your suction superheat
when u working with a very high suction superheat,your oil it will get hot and that it will effect your end compression temperature,so try to keep your suction superheat as low possible,in that way u be able to cool your oil and keep your end compression temperature with in normal condition
