You should be getting a good Lift on with this chiller. Is your cooling tower a crossflow or counterflow type or evaporative tower.
@corporatefacilitiesgroupin9291 Жыл бұрын
Thank you for joining us and your comments and question. Usually the lift is solid; sometimes on colder days before we turn over to the economizer, the lift can vary a bit. Generally, the chillers are very solid and reliable. It is a crossflow tower.

Mr Paul what was evaporator your approach temperature on these chillers? 4-6°F approach
@corporatefacilitiesgroupin9291 Жыл бұрын
Thank you for your joining us and your question. I will need to pay more attention, but I would say you are very close at 4-6 degrees F. Perhaps, 3 to 5 F might be closer. I will say that the old R-11 Trane units, were capable of colder chilled water than these newer units are. It is not really noticeable in the building climate control or performance.

That's very odd that you're using pneumatic actuator, so you need an air compressor for air supply. These Daikings chillers use R-134a refrigerant. Now I have a question, is this plant a load based system or a flow based? Are your AHU'S VALVE TWO WAY OR A THREE WAY VALVE SYSTEM? IF THE VALVES ON THE AHU'S THREE WAY IS A FLOW BASED SYSTEM. IF ITS A 2 WAY VALVE THEN ITS A LOAD BASED SYSTEM.
@corporatefacilitiesgroupin9291 Жыл бұрын
Hello. Thank you for your comments and questions. Yes, this plant does use pneumatic actuators and a very large multi-stage air compressors. The air is used in other applications in the facility. The building is very high and even with extensive lightning protection, we had terrible time with lightning strikes and surges. Many electronic devices in the plant are affected. We have found electronic actuators slightly fussy and unreliable. In over twenty years, even after retrofit, we have only had to rebuild two actuators. Very reliable. The system is load-based. It uses 2-way CW valves at the AHU's. Thank you again for your interest and joining us on the channel.

Is this chiller facility a 14-18°F Delta T plant? What's your current COP? and how much kW/ton does it consume. Also what's the EER? I imagine you have either an airside or waterside economizer
@corporatefacilitiesgroupin9291 Жыл бұрын
Thank you for joining and for your comments and questions. You are close on the Delta T. Maybe 15 to 20 degrees is closer. Yes, we have a waterside economizer. I am not privy to any costs or electrical bills so I cannot comment on that with any accuracy. The building owners have commented that the electrical costs are much reduced (obviously) over the old chillers.

You said condensing pumps take water from condenser and pressure it to the cooling tower and this is wrong .. The condensing pump pressure cold water from cooling tower to condenser and it is found in return side from cooling tower to make sure there is always enough flow of water to absorb heat from hot gas refrigerant
@luigiluigini95007 жыл бұрын
Yes the electric actuators fail all the time. Those pneumatic valves are hard to beat as far as reliability and longevity. Looks like a nice facility. I'm always stuck working in shitholes with lack of maintenance. Those chillers say daikin mccquay, I hope they are better quality than these new daikin units that Goodman was putting out.

Some York YMC2 chillers would have been a better choice :) Cool video though! -York Chiller Mechanic
@luigiluigini95007 жыл бұрын
Derek Conner I have serviced /repaired them all and I must say York is by far the worst. They are quality , however their software is not user friendly and plagued with bugs. We've also had several issues with poor connections causing weird alarms that will come and go at their own will. Trane is by far the best platform. I do speak of equipment thats down in Florida. The high levels of humidity may come into play with my opinions on these machines. I don't know how yorks do up north.
@derekconner49937 жыл бұрын
Luigi Luigini Hmmmm that is interesting considering I have never had any of those particular issues with any York, water cooled or air cooled. I'm not biased, but I am master factory trained by York and know most issues that they bring a customer. I'm interested in the bugs, and connection issues. Are we talking about old York machines or newer? Huge difference between them.

Derek Conner Yes 15 + yr old YCAV Air cooled screw chillers. I may have exaggerated a bit but the York's are definitely the least user friendly for someone who is not specifically trained for York's.

im going to correct you on a couple of misleading things in the video :) first of all its not important but the old refrigirant that you called r11 is achually called r12. and the newer gas that the new plant is using (r134a) is not toxic but it deprives oxygen in the room if there is a big leak so you will suffocate without even knowing that there is no breatable air in the room and possably die. that is why there is a saftey system in place. not saying this to be a smartass but i like pople to learn correct information. :)
@corporatefacilitiesgroupin92918 жыл бұрын
Thank you for your interest in our video. I am going to have to say that while we appreciate your input, you are incorrect. The machines removed from this chiller plant were indeed 450 ton Trane R-11 machines. R-11 was used in old chillers frequently, and while it was a very good refrigerant, it was a ozone killer. Chillers of this type are low pressure appliances and R-11 was used. R-12 is primarily used in other appliances and applications. As far as toxic properties for 134a, a discharge in this plant of this amount of refrigerant would not be a good event. There is occupied office space below the plant. If there was a fire present, the 134a turns into a bad scene. Displacement of oxygen is toxic enough for me! Why take a chance? Treat all chemicals with care, read the safety sheet and limit exposures.
@TheSteelArmadillo8 жыл бұрын
R-11 is a thing. If the man says he had it, we must believe him. However, the distinction that you make regarding the word toxic is significant. A toxic gas and an asphyxiant gas are thoroughly different, and the terms should not be used interchangeably, as they are responded to in completely different ways. These Magnitude 400D chillers should be charged with approximately 1240lbs of 134a each. Were one to rupture, it would dilute the oxygen (not necessarily displace, like argon) in that space greatly, posing a health risk. However, a toxic release would warrant a shutdown of air moving equipment to restrict its coverage, whereas an asphyxiant release would warrant the introduction of forced outside air. In any case, tell the chief he has a nice setup.
