I had good luck with SimScale. The value is in their engineering assistance. With the paid subscription they will basically hold your hand through the beginning of the project, and as you get better at it they will log in and look at your model if you get stuck on something.
You can fiddle...
A hot gas bypass valve (regulator) is a pressure actuated valve that is connected to the discharge of the compressor (valve inlet) and to the suction side of the system. It can be hooked directly to the suction or in between the expansion valve and DX distributor. There are special distributors...
I used to buy them for our MRI chillers that were going to areas such as Las Vegas, Phoenix, etc.
We never took real data as to performance gains, but they ran when it was 120 F on the roof.
Some guy in AZ built them for us but can't remember his name (I don't work for that company anymore)...
It is a hot gas bypass valve and a desuperheating expansion valve connected toghether via a "desuperheating chamber."
You could do the same thing with installing the parts separately. I think it is marketed to HVAC applications because in a refrigeration system there is a good chance the system...
Sure, it will work. However, as posted, you won't get full modulation because you are only controlling on/off devices, but you will remove the offset like with a standard differential control.
Check out www.kele.com. They have this nifty contoller that will hook up to the output of a process...
I am having some problems with the automatic pipe fitting placement feature with the pipe routing command.
I took the standard ANSI butt weld 1" elbow, created a copy, and added it to the library. I then adusted the dimensions to create 4" elbow.
Using the database administrator I updated...
DOes anyone know of a manufacturer of chilled water storage tanks that specializes in HVAC applications. This is for a 120 ton Trane screw chiller with a short loop. Looking for around 700 gallons.
Does the tank have to be rated to 125 or 150 psi, even if the system pressure will never be over...
If you are looking for a completely packaged unit, that all you have to do is hookup power and water pipes, you need to look at a process chiller. Carrier Aquasnap as Chris mentioned is a good chiller for the price, but the smallest is 10 tons.
Process chiller guys make totally packaged systems...
I hope I can explain this without pictures.
Assuming a vertical accumulator...
There are two connections, the inlet and the outlet. The inlet connection extend into the inside of the accummulator a couple of inches, then just ends. The outlet connection extends into the accumulator all way to...
Sure it will work!
But...
*You will have less capacity than you did before.
*Need more refrigerant
*Need to run power to the condenser.
*Need considerations for head pressure control depending on where you are.
If this is something you are doing yourself, it will be cheaper than a new...
For this low of temperature you need the following:
1. Condenser flooding head pressure control. It is the only thing that will work. Sometimes called a "Headmaster" after the brand name of the valve by Alco controls.
2.Heated, insulated receiver. You will HAVE to have a receiver with the...
