has anyone here ever worked with ammonia as a refrigerant?
what training is needed?
where do you get the training?
where do you purchase ammonia equipment and refrigerant?
How much more efficient is ammonia over R-22?
What should the discharge air be on a make up air handler unit in the summer (cooling) mode of operation? The make up air unit has 2 stages of DX cooling and a hot water reheat coil with a three way modulating valve. I want the coldest discharge temp so not to load the existing mech cooling...
question???
i have a 1075rpm 240v 2hp electic motor. If I connect it's shaft to a 10hp gas engine. Will it product 240volts while the gas engine is spinning at 1075rpms??
Discharge Superheat is a subject i would like to know alot more about.
I know it is the Discharge temperature minus the condensing saturated temperature.
Example: Discharge temp. = 142*
Condensing Sat. temp. = 91*
so the discharge superheat would be = 51*.
i was told that you should only...
I am relaying a question?
A screw compressor is scraping the housing at letters A,R,Q. What do you think the problem is? (¿¿¿Bad thrust bearings MAYBE???)
i'm working on a trane compressor m# CRHR600C-7RA0
s# J08031266AR which was installed about 6-months ago. it is making a unusual noise (sound like metal on metal) the compressor has a one-year warranty from the rebuild company. i want to try to get it replaced while it is still under warranty...

previously i asked about hydrogen when i should have wrote helium.
i'm looking for a pressure-temp chart for helium in PSIG and deg. F..or any other form.
if i were to install a suction line accumulator in an R22 refrigeration system right before the compressor. for the propose of preventing any liquid refrigerant from getting back to the compressor. how does the oil get back to the compressor with out the liquid getting back.
i am looking for a pressure-temp chart for hydrogen in PSIG and deg. F
i am trying to condense hydrogen into a liquid by compressing it to xxxx psi and then cooling it xxxx degrees. but i would like a chart in imperial conversions.
I’m having problems with a YORK 230 ton air cooled screw machine.

Roughly, for the past year, once every three months, it trips out ckt#2 with this fault message: “High DSCH Temp”. Now it is appearing more frequently.
According to troubleshooting guide in the...
