First day doing industrial refrigeration. Worked on an ammonia chiller and this video just simplified all the shit that I saw today. I bled out the oil into a bucket and got a good whiff of that good ole ammonia. Smells like death.!

Great explanation... I have an alternate method to this that is way more efficient than a cascade. We have hit -112c with a single stage system and can get much lower. Patent Pending!

[@vijithamuthugala1829]

Awesome presentation ! . I found this while searching for Amonia system issues as I am having prolong issue in my Ammonia compressor . Grateful if you could support me to solve it. We have a two stage ammonia compressor connected to Blast freezer of -40 C . At start it perform well and while room temperature down to -30 C Compressor oil pressure reduces gradually below to the set point ( 1,5 bar) and shuts down . All the components were checked , replaced ( bearing , pump , filters , oil etc ) . nothing didn't solve the issue. But one day in a test run suddenly , the machine picked up the oil pressure and run as normal. It continuously ran for two weeks without problem and all of a sudden again the same issue occurred . Now we are helpless . If anybody can support us, it is very much appreciated. !!

[@allanweitman]

I'm currently taking my power engineering level 5 and this is super helpful for understanding when you are just learning. The videos they have with the course are so boring/terrible/old. I'm so glad I found these

[@stevelamperta865]

The regulator valve and expansion valve are almost the same , the only difference is the expansion valve has much better and consistent adjustment for the very much important amount of liquid ammonia going into the evaporator . The regulator valve controls the pressure differential between the condenser and receiver . the head pressure runs around 125 an 150lbs , an the receiver runs at 75lbs pressure differentials are key , as that's how the system works. I was a manager of several companies with ammonia refrigeration systems .

[@pradnyashankardas6435]

Yes great, Pressure difference is the key

[@thomassim5600]

What will happen if there's a high pressure differential

[@brandonbarnard3660]

[@alnonymous9361]

slight error... the cascade condenser is the evaporator of the high temp circuit and the condenser of the low temp circuit. At 8:00 you said it backwards.

[@DavidFMayerPhD]

Questions: 1. What material is used to contain the ammonia? 2. How do you keep the ammonia dry? 3. Why do you use isenthalpic expansion instead of isentropic expansion which should be more efficient, at least, in principle? 4. What kind of seals are used on the compressors to keep the ammonia from contact with the motors?

[@juansalazar4325]

1. You can contain ammonia in tanks, while pressurized. 2. The only way the ammonia get wet is if there is a leak and air gets in, this happens in cases in which you are working in vacuum. To vent out the air, you use an air purger. 3. For this you need to understand the refrigeration cycle with a pressure vs enthalpy chart. In a sense, you need to keep the enthalpy in the same level after it passes through the condenser. 4. The motor is connected to the compressor through the shaft. The compressor would have a shaft seal to keep the ammonia within the compressor. There are videos on how a shaft seal works. Hope it helps!

[@DavidFMayerPhD]

@@juansalazar4325 Clarification: You wrote: "You can contain ammonia in tanks" What material are the tanks made of? "You need to keep the enthalpy in the same level after it passes through the condenser." Why?

[@CoastalSphinx]

@@DavidFMayerPhD Ammonia is contained in steel. Steel is adequate and inexpensive. Never use copper or copper alloy such as brass or bronze - ammonia will corrode them very rapidly. Isentropic expansion is difficult. A machine is needed to extract work. The fluid is a gas/liquid mixture so a controlled expansion is even more difficult. And the efficiency loss from the isenthalpic expansion is small because the amount of expansion is small, most of the expansion is due to isothermal evaporation. So even though isentropic expansion is best in theory, practical limits favor isenthalpic expansion.

[@entity6966]

1. stainless steel and black iron pipe 2. using purgers and to take out non condensable as well as getting anhydrous ammonia when you first fill up. 3. i dont know tbh 4. its a carbon and material that sits on the shaft of the compressor. called the shaft seal that prevents push back. it usually sits in oil to prevent any leakage and they get replaced every so often depending on the wear they get. usually there isnt any direct contact what so ever with the motors unless theres a huge problem.

One key factor that was forgotten is that ammonia is highly corrosive to anything containing water, including your skin. Copper also can’t be used on ammonia systems at all

[@bigkirbyhj666]

How about galvanized steel?

thank you for this vid. im gathering ideas for LIQUID AMMONIA :) keep it up!

[@JohnSmith-xk8rr]

NH3 systems require a T-machinary room classification. Without proper emergency pressure release systems, diffusion and fire suppression the risk of a toxic explosion is too high and therefore only certified techs can make physical changes to the system and certified RO/PE's can operate it. If you want to experiment with refrigeration, I'd recommend using something inert and learn about corrosion, piping codes first. I have personally rigged a commercial AC to the side of my house and use the heat in my greenhouse. It can take litres of water out of the air and cool my entire place below 60 degrees. The waste heat can become it's own project. If this field interests you there's extremely good jobs in heavy industry. I'd say it is less of a career because you will always be training and working on new systems unless you find a chief plant operations position but eventually you'll want a bigger system to operate as you gain more firing time and experiance.

[@gregorymalchuk272]

@@JohnSmith-xk8rr Do You have it rigged as a reversible heat pump, or did you just place a condenser in the greenhouse? There are some circumstances where you may need to cool a greenhouse too. Is the air conditioner new or an old unit removed from a residential home? What refrigerant does it use?

[@stevelamperta865]

The expansion valve and the regulating valve you have backwards ! The expansion valve goes in between the evap and ammonia pump . And normally a single stage system doesn't use ammonia pumps , they run off the receiver pressure . the regulator valve belongs in between the condensor and receiver to put a diff of head pressure of around 150lbs to 75lbs receiver pressure.

[@bradvincet1848]

Thanks for clearing that up, I was going to ask the same question. If they're going to make informational videos they need to get the facts straight.

[@entity6966]

they can and do have pumps. you're thinking of a single stage system with control pressure receiver and dump tanks, which have no pumps but instead rely on a set pressure of ammonia sitting in a vessel to be fed into a tank and then pushed by hot gas to the evaps.

In the video it is shown that cascade intercooler or heat exchanger is used to maximize the refrigerating effect.

2:12 You're forgetting that when Anhydrous ammonia reacts with water, it generates heat. At certain storage densities, this is bad… you get a runaway reaction which leads to a massive explosion. This is what happened in Beirut.

[@tobiasfate9422]

Hello sir, i would like to clarify and ask. The equalizing line's purpose is to equalize the pressure between the compressor outlet/condenser inlet with the ammonia receiver to allow the liquid refrigerant flow towards outside the condenser outlet more easily. Then, if there were no equalizing line existing between those two points, would there be an overflow, followed by back flow? Then the equalizing line's another purpose is to prevent the liquid refrigerant flowing back inside the condenser. Please correct me if I am wrong sir, thank you very much.

[@joshroberts243]

Question, you mention at the end in a cascade system that it sometimes uses 2 different refrigerants, allowing you to use less ammonia. But you said a couple times in the video the refrigerants never make cntact with air or water ad always sealed. That makes this a closed loop system and the refrigerants shouldnt be consumed no?

what's the difference between a liquid separator and liquid accumulator?

[@entity6966]

the accumulator just holds liquid and gets pushed out by the discharge pressure of the EQ line. A separator has liquid that has been pushed through from the accumulator and then it is sucked on by a compressor from the top. liquid stays at the bottom and the vapors get pulled through by the suction.
